Khaled Hosseini Essay At parties, when all six-foot-five of him thundered into the room, attention shifted to him like sunflowers turning to the sunTranslating a book into a movie can be a very elusive task for many reasons. This is due to the fact that a book has many key points in it and compressing them all into a certain time frame can be very challenging. Mark Forster’s adaptation of Khaled Hosseini’s novel the Kite Runner is a weak portrayal of what the author had originally wrote. The movie consisted of some bad casting choices. It also consisted of some significant and harmful cuts to the novel. Although the director’s intention to recreate a very well written story into a movie was a great idea, the author could have given more attention to some critical and important aspects of the novel. The directors casting choices changed some of the important traits, which took away the true understanding of the characters. In the book, Khaled Hosseini states that Hassan is a descendant of Mongol heritage, which was an indicator of his status in society. As a Hazara young Hassan’s actor in the movie, blended in with the rest of the actors, as he did look like a Mongol. Another obvious flaw in Hassan’s character in the movie was the fact that he did not have a harelip, which represented the fact that he was a Hazara and had no money for it to be replaced. Baba is also another great example of how the director made some bad casting choices for the movie. In the book Baba’s character was described as a strong, intelligent and intimidating man â€Å"At parties, when all six-foot-five of him thundered into the room, attention shifted to him like sunflowers turning to the sun†.

Antenna Systems For Radar Applications Information Technology Essay

Antenna Systems For Radar Applications Information Technology Essay The project will examine a variety of beam forming techniques which can be used in order to make radar electronic beam steering feasible. Commonly used mechanical rotating antennas for a 360 degrees views coverage are difficult to operate and expensive to implement. Thus, electronic beam forming is an attractive solution. This report is mostly interested in radar applications performing in 24 GHz frequencies, which can be used by car industries, in order to avoid obstacles on the road, for example, or security radars, covering 360 degrees views. Radar 2.1. Radar Definition Radar means radio detection and ranging, determining thus the original and still significant application of radar. The main reason for using radar is to estimate certain characteristics, such as the position, motion and presence of the specific surroundings in which the user is interested. Radar is actually a sensor which transmits electromagnetic energy into the surroundings and detects energy which is reflected by objects. If a directive antenna transmits electromagnetic energy through a narrow beam it is easy to predict the bearing of an object because of the energy reflected of it. The time needed for the transmission and reception of the energy represents the distance between the radar and the object. [21] Kinds of Radar There is a great variety of radars. Some radars provide navigation aid and safety on small boats and their size might be less than 15cm. Others are widely used by the police in order to measure the speed of the vehicles. Moreover, there are some radars so large as to cover many kilometers of land, long arrays of antennas and they all work together in order to supervise the flight of astronomical bodies or space vehicles. In addition, there are many radars at airport, with a more common size and rotating antennas. Finally, there are several radars, more complex, for mobile use. [21] Radars can be classified in many categories. As much as the waveforms are concerned, radars can be classified in 2 categories, they can be either Continuous Wave (CW) or Pulsed Radars (PR). CW radars use different antennas for transmission and receiving, and they emit electromagnetic energy continuously. Unmodulated CW radars precisely determine the target radial velocity and angular position, while information about the target range have to use some form of modulation in order to be gathered. In order to search and track target velocity, primarily unmodulated CW radars are used. Pulse Radars (PR) use a series of pulsed waveforms, mostly with modulation and can be separated based on the Pulse Repetition Frequency (PRF) in 3 categories, high, medium and low PRF radars. CW and PR radars are both able to determine target range and velocity by using different forms of modulation. [23] Continuous Wave Radar (CW) CW radar sets continuously transmit a high-frequency signal. Then, the received signal is permanently processed. In such a system, two problems have to be solved: avoid a direct connection between the transmitted and received energy (feedback connection), conduct the received echoes into a time system capable of doing run time measurements. A feedback connection can be prevented by: spatial separation   between the transmitting and receiving antenna frequency dependent separation  by the  Doppler-frequency  during the measurement of speeds. [4] Frequency Modulated Continuous Wave Radar (FMCW) CW radars are not capable of measuring distance, because the timing mark necessary lacks, preventing thus the system to time precisely the transmit and receive cycle and exchange the measured round-trip-time into range. This problem can be solved by using phase or frequency shifting techniques. As far as the frequency shifting method is concerned, a signal is used, which continuously changes in frequency around a specific reference, in order to identify stationary objects and measure the range. In order to achieve an up-and-down or a sawtooth-like alternation in frequency, Frequency-Modulated  Continuous  Wave radars (FMCW) are used, changing the frequency in a linear fashion. By constantly changing the frequency, there will be a difference between the frequency of the echo signal and the one transmitted. Thus, the difference  transmitters frequency shift will be relative to round trip time  and so the range  of the target too. The frequencies can be examined, when a reflec tion is received, and by comparing the received echo with the actual step of transmitted frequency, a range calculation like using pulses can be done. Consequently, the range of the stationary objective is given by comparing the transmitted and received frequencies. It is difficult to make a broadcaster able to send out random frequencies cleanly, and as an alternative, this frequency-modulated continuous-wave radar, use an easily changeable ramp of frequencies up and down. If the frequency modification is linearly over a broad area, by making a comparison among frequencies within this region, the distance can be easily determined. It is possible to measure only the complete value of the difference and thus, the results with increasing frequency modification signify a decreasing frequency change at a static scenario. [4] Characteristics e of FMCW radar: measuring the distance is potential by comparing the definite frequency of the received signal to a given reference (regularly direct the transmitted signal) the time required for transmitting a signal as longer than the duration of the measurement of the installed maximum range of the radar [4] By selecting the appropriate frequency deviation per time unit, the radar resolution can be different, and choosing the frequency shift duration, the maximum range can be varied. For instance, if the linear frequency of radar increases over 1  ms duration, the time-limited maximum range might be 150  km. If the maximum frequency deviation is 65 MHz, then stay about 433 Hz per meter for the filter for analysis. It is important that the amount of frequency modulation is considerably greater than the estimated Doppler shift otherwise, the outcome will be affected. The most common and easy way to modulate the wave is by linearly increasing the frequency. In this way, the transmitted frequency will change at a continuous rate. If a single antenna is used, a ferrite circulator has to separate the transmit and receive. However, using to different antennas, one for transmission and one for reception, is easier and cheaper to perform. On a ordinary substrate transmitting and receiving ant enna are placed exactly above each other as an antenna array. The direction of the linear  polarization  is rotated against each other by 180  degrees. An extra shielding plate reduced a direct cross talk (i.e. a direct coupling of both antennas) usually. From this direct coupling, arises a signal, which is suppressed due to the same frequency, since the measurement is performed to as a frequency difference between transmit and receive signal. [4] Radar Beamforming In order to create a beam with the appropriate and desired characteristics, radar beamforming, which combines signals from a set of sources, is essential. As much as an RF antenna system is concerned, each source may be a single array element or a subarray. A steerable beam is able to control the combination process electronically. Moreover, it can be replicated so as to create various independent beams, limited by hardware difficulty, complication and losses. [22] 3.1. Analog Beamforming A feed system is a network used in order to connect the antenna input to its radiators. The main reason for using such a system is to transmit power to the elements or collect signal from them. (transmit mode, or receive mode). While being on transmit or receiving mode, the required phase and amplitude excitations needed for the radiation performance must be maintained. The feed network is able to scan the beam, select among different antenna beam shapes and communicate with active sectors, by containing several switches and other devices, appropriate to execute such processes. Moreover, the feed network may contain amplifiers and other active devices. There are also many new developments, such as Switch matrix systems, Butler matrix feed systems and Vector transfer matrix systems, but the most significant are the RF lens feed systems. [1] 3.1.1. RF Lens One of the biggest problems when using a transmission line feed network is that amount of losses. Therefore, systems which are based on RF/optical principles are preferred. There is a large variety of RF Lens and many RF/optical feed systems also incorporate different types of beam scanning functions. RF refractive lenses are similar to their classical optical counterparts, which function by using the refraction amongst different materials. When using constrained lenses, the waves are forced to follow some specific paths, like in a geodesic lens. Another type of lens is the bootlace lens which in which the signals between the input surface and the output surface are routed on transmission lines. Occasionally, a conformal array feed uses different combinations of lens types, or lenses and matrices. Small array antenna elements are used by an RF lens as input/output probes that couple to the lens region. These probes exist in an array environment which is characterized by reflections a nd mutual coupling and the associated design problems. In particular in circular lens designs, there can also be standing waves caused by reflections from the opposite side of the lens. Another problem is the variation of the element phase center with frequency. [1] Rotman Lens A Rotman lens is a parallel-plate structure used as the beam forming network (BFN) for a linear array of radiating antenna elements. It is easy to form a beam forming network suitable for use with a planar array, by stacking numerous lenses. Rotman lenses are preferred because of the advantages that they offer, such as ease of manufacture, light weight, low cost, monolithic construction and availability of many beams at the same time. Rotman lens is capable of extremely wide-band operation, because it is a true time-delay device which produces frequency-independent beam steering. Because of these characteristic, Rotman lens is a possible candidate for use in multi-beam satellite-based applications. [2] The electrical area that a Rotman lens occupies is very large (usually hundreds of square wavelengths) and because of this, an entirely precise analysis is not possible. The planar circuit approximation applies to structures which are electrically thin in one dimension, like parallel-plate lenses. The effort required for their analysis is reduced to that of solving a (line) integral equation for the relationship between the RF voltage and current at the periphery of the structure. [2] The R-2R Lens The R-2R lens feed (Figure 1) has feed ports on the perimeter of a parallel-plate lens with radius R, in order to illuminate the output ports on the opposite side of the lens. These output ports are linked to the element ports on the 2R radius circular array with cables of equal length. The number of feeding ports is half the number of element ports. This type of arrangement allows all feed points to be ideally focused, resulting in a plane-phase front. In order to scan the antenna beam at angle ÃŽÂ ¦, the feed point has to be moved an angle 2ÃŽÂ ¦. One illumination taper can be achieved, by combining three to four adjacent feed ports, resulting in lowered sidelobes. [1] Figure1: The R-2R lens feed system [1] It is essential to add several switches on the lens ports, in order to scan the beam. One has to be allowed to use numerous beam ports at the same time in order to achieve a multiple beam generation. This problem could be solved by using half the lens for beam ports and connect the other half to a 90 ° arc array. R-2R lens are considered to be a special case of the Rotman lens, which is typically used for linear array feeds. Furthermore, for circular arcs up to 90 °, the Rotman lens can be used. Actually, the curvature does not have to be circular, as the design in general, curvature of lens input and output lines, cable lengths, and so on can be optimized together with the array shape. It is possible to achieve ideal focusing in the Rotman lens only for three beam directions. [1] The R-kR Lens The R-kR lens feed system has as much ports on the lens as there are radiators on the circular array. In order to cover 360 ° views, the lens ports have to be used more than once, both as feeding points and for connecting to the radiating elements. In order to achieve this, switches are used, circulators (Figure 2), or two lenses at the same time. The radiators placed on radius R are connected by cables of the same length to the ports of the circular lens with radius kR. When k is about 1.9, a planar phase front for rays within a sector of about 120 ° is obtained. This shows that the lens is nearly two times the size of the circular array, thus, it cant fit inside the circular array if it is not filled with a dielectric with permittivity more than 4. If broadband radiators are used, the R-kR lens-fed circular array can be very broadband. The bandwidth could be limited by using switches or circulators. The phase center of the radiators is a design parameter of critical importance and must be located on the design radius R. [1] Figure 2: The R-kR lens, here with circulators. [1] In order to limit the focusing performance, several types of element have a phase center which is able to change position with frequency. [1] Mode-Controlled Lenses A radial transmission line which forms a circular parallel-plate lens is possible to act like a circular array feed. If it is excited by several probes placed close to the center, the modes generated will direct the energy toward a part of the lens periphery. Therefore, by controlling the modes using phase shifters or a hybrid network connected to the input probes commutates the excitation. Then it is easy to connect these pick-up probes to the radiating elements, via additional phase shifters if needed. [1] Luneburg lenses In order to achieve wide angle scanning, the Luneburg lens, is the appropriate and desired device. As far as land mobile operations are concerned, an antenna able to scan in a two-dimensional (2D) plane is required, particularly if the scan angle is large. The Luneburg Lenses are used in order to provide single or multiple mechanically scanned beams, at microwave frequencies. Nevertheless, because of the advent of phased arrays the lenses are now usually used for radar applications as a wide angle passive reflector. This is why nowadays there are appropriate lens configurations which can be established by permitting the inclusion of controllable dielectric material into a Luneburg Lens so as to make the lens suitable for electronic scanning at 24 Ghz. [1] Digital Beamforming When performing beamforming in the digital area, it is called digital beamforming. The realization can demand huge volumes of digital information to be processed at extremely high rates, but current improvements in processing hardware have made Digital Beamforming a useful alternative to RF combining in many ways. Moreover, it has allowed the formation of systems which were not practical with legacy technologies. Below are presented the benefits of Digital Beamforming. [22] Simplicity of hardware If the RF and analog hardware becomes a minimal device, collecting data, it would be an ideal case. Then, all the difficult and complicated process of the signal is done in firmware, which is a more flexible and gainful way of processing comparing to RF plumbing. In addition, it is possible that the overall size of the system, as long as its weight, will be reduced a lot, and this is particularly significant in airborne systems. [22 Replication Digital beamforming is the best option when many independent beams are needed. By using digital beamforming, it is easy to form each beam completely digitally, without any analog or RF hardware further required. The quantity of beams like these is then partially limited by power, speed and synchronization of the processing elements, which become even more cost-effective and flexible each year. [22] Scanning and Tracking It is not possible to steer electronically each beam (e.g., to track a moving source). However, by using the precisely same stream of digital samples from each antenna element, it is potential to turn each independent beam to a different source. Thus, it is easy to reduce extremely difficult receiver scenarios to firmware buildings blocks which are now usual. [22] Flexibility These digital systems can be adapted without any difficulty to varying requirements, such as multipath combination, application bandwidth, tracking requirements or interference rejection. A SMOP (Simple Matter of Programming) is able to perform numerous adaptations. [22] Radar An array antenna which is a low Cost Transmit/Receive one provides agile beams to track multiple targets at the same time. [22] Anything that can be done by using an analog beam forming can easily be done digitally too. Choosing to do everything digitally might lead to several difficulties because of the extreme requirements on data transmission, storage, and signal processing. However, nowadays such problems are easily solved because of the rapid growth of computer power, either software or hardware. When using an analog reception beam forming, the element signals are combined with weights determined by feed networks and/or phase and amplitude controlled receiver modules. In digital computer, it is possible to do the same operations on the element signals just by converting analog signals to digital ones. Thus, the formation of many receive beams can take place at the same time, without feed losses, which are common when using analog systems. Moreover, the element modules in the digital systems have low noise amplifiers (LNA) preceding the analog-to-digital conversion. A lossless beam forming is created as t he LNAs set the signal-to noise ratio, so that it is not affected by transmission losses. The advantages of a digital beam forming in this case are not so obvious. After the transmission of the beam, it is not possible to change the beam shape or to perform any other signal processing. Nevertheless, digital synthesis of the transmitted waveform on the element level combined with DBF on reception can offer remarkable system capabilities in terms of, for example, LPI (low probability of intercept) radar with jamming resistance. A wide transmission beam illuminating the area of interest and multiple, narrow, digitally formed receive beams has also been suggested for LPI systems-ubiquitous radar and OLPI radar (Omnidirectional LPI). There are many aspects which can best be performed digitally, such as the need for amplitude and phase control, polarization control, switching of the active sector, compensating for element patterns in the beam steering algorithms and calibration. A DBF ant enna system has a combination of numerous subsystems and components. Receiver channel imbalance, , A/D converter offset errors, amplitude and phase errors and frequency dependent errors are some of the possible imperfections in these subsystems and component which can influence the performance of the overall system. The type and requirements of each processing used influence the importance of such imperfections. Usually, array calibration and special error correction schemes are included in the antenna system design. [1] 3.3. Beamforming Transmitter Architectures Several beamforming transmitter architectures exist, suitable for integrated circuit implementation as well as many well-known topologies for separate implementations of phased array transmitters. The goal is topologies appropriate for performance in consumer products at 24 GHz. Electrical beamforming is achievable if the phase of the signal to each antenna element in the array is separately set. Moreover, a larger number of patterns can be achieved and the sidelobe level can be reduced compared to uniform power distribution if the power to each antenna element is set individually. [3] 3.3.1. Baseband Phase Shifting In the baseband phase shifting architecture the phases and amplitudes of the signals are created in the digital baseband. The phase control is very accurate, but the architecture demands an entire signal path between the baseband and the antenna for each element (Figure 3). Also, the architecture can be called digital array, because the beamforming is being performed in the digital domain. Such an architecture lead in a large hardware cost and power spending because there are many signal paths, but also in big flexibility. As a result, this architecture is perhaps very complex for radar at 24 GHz. In order to transmit individual information in various directions, in MIMO systems (multiple input multiple output), the flexibility of the architecture with parallel paths is available too. [3] Figure 3: Transmitter architecture for baseband phase shifting [3] 3.3.2 Local Oscillator Phase Shifting Phase shifting can occur in the LO path as well (Figure 4) Moreover, it is likely to use phase shifters in the signal path, at IF or RF. Whether performing the phase shift at LO or RF or place them at different places, the same amount of hardware is achievable. If they are placed in the LO path, amplitude variation among dissimilar phase settings is less significant if the mixers are driven hard. In this way, amplitude variation in the LO path will not influence the signal path a lot. Thus, it is easier to implement the phase shift in the LO path. [3] Figure 4: Transmitter architecture for phase shifting in the local oscillator path, polar modulation [3] 3.3.3. Offset Local Oscillator Phase Shifting If the power amplifier and local oscillator are used at the same frequency, injection pulling is possible to occur. It might not be easy to accomplish a sufficient isolation so as to avoid the corruption of the oscillator signal by the PA. To moderate this on an architectural level, offset LO phase shifting may be used as shown in Figure 5. Beamforming transmitters have applications like radar (24 GHz and 77 GHz) and WLAN (60 GHz) which are placed at high frequencies. It is valuable to use the lowest frequencies possible on the chip, and multiply the frequency close to the PA. A reduced VCO frequency makes allows a wider tuning range, and the increasing MOS varactor quality factor. [3] Figure 5: Offset local oscillator phase shifting for beamforming transmitter [3] 3.3.4. Ring Oscillator Based Phase Shifting A ring oscillator which has a tunable phase shift among the oscillating elements is used in such architecture (Figure 6). The tuned oscillators in the ring are separately detuned from their center frequency. The LC-loads is capable of sustaining up to +-90 degrees phase shift. It is important that the phase shift around the ring is constantly equal to 360 degrees, or a multiple thereof. The phase shift among consecutive elements is zero degrees if each oscillating element is non-inverting, and no excess phase shift is introduced in the loop. By putting an excess phase shift of KÃŽÂ ´ degrees it will have as a result a phase shift of ÃŽÂ ´ degrees in each of the equal K oscillators in the loop. [3] Figure 6: Transmitter architecture for variable phase ring oscillator in a phase locked loop [3] 3.3.5. Radio Frequency Phase Shifting The phase shifting which is the most hardware efficient, including numeral building blocks, is to carry it out just before the power amplifier. The power amplifiers are the only circuit components that have to be duplicated (Figure 7). The disadvantage is that the phase shifting is being performed at the highest frequency and signal level in the system. When an envelope modulation scheme is used, the linearity of the phase shifters may be a problem while noise is not as significant when the power level is high. It might be useful to implement the phase shifters at the highest frequency. If transmission lines are used as separate phase shifters, they become shorter with frequency. This is an ordinary architecture in radar systems. Several fixed phase shifts are in that case implemented and switches controlled by selection logic determine the phase shift. Certainly, the transmission lines are linear and thus, these phase shifters can easily be used in envelope modulated systems. Moreover, the delay is stable over a wide bandwidth. A set of fixed phase shifts is then implemented and switches controlled by a selection logic choses the phase shift. Of course the transmission lines are linear so these phase shifters can very well be used in envelope modulated systems. Another advantage is that the delay is constant over a wide bandwidth. [3] Figure 7: Transmitter architecture for phase shifting in the radio frequency path. [3] Applications for 24GHz Radar Sensors Modular 24 GHz Radar Sensor for Digital Beamforming on Transmit and Receive In order to increase the angular resolution, numerous switched transmitters are preferred, as they need less hardware effort. The FMCW radar sensor is the best solution, providing up to eight transmitters, switchable ones, and eight receiving channels which provide parallel receiving, and they all allow digital beadforming. An innovative switching technique via switchable amplifiers is preferred. [5] Four Channel 24-GHz FMCW Radar Sensor with Two-Dimensional Target Localization Capabilities Results on the angular measurements are improved when using an FMCW radar sensor, compared to standard beamforming methods, as far as the target localization is concerned. Furthermore, the determination of other characteristics required will be allowed, such as the range or velocity. [6] . 24-GHz Automotive Radar Transmitter with Digital Beam Steering in 130-nm CMOS (Complementary metal-oxide-semiconductor) Many Pas are connected to different antenna elements so as to control the steering of the beam. The output phases of the PAs are controlled separately through 360 degrees by binary weighting of quadrature phases. The circuit has 18 PAs,and each one of them delivers 0 dBm to the antenna, ensuring an output power of 13 dBm. The antenna array, which is constituted of 18 elements, will be 11 cm at 24 GHz and will have 12 dB directivity and a half power beam width of 5 degrees. [7] Design and Performance of a 24-GHz Switch-Antenna Array FMCW Radar System One transmitter, one transmitting antenna, four receiving antennas, one receiving channel and an SP4T switch (single-pole four-throw) are the elements which compose a 24-GHz FMCW radar system. In order to increase the inter-connection loss and create a compact whole size, radio-frequency (RF) and intermediate-frequency (IF) circuits are integrated in the antennas. The receiving antennas are sporadically switched to the receiving channel. Beamforming methods are used in order to evaluate the performance of such a developed system, by estimating the angle, velocity and range. [8] Imaging Radar Sensor Front-End with a Large Transmit Array Automotive applications need medium range imaging radars, such as the 24 GHz imaging radar front-end. In this radar, a large switched transmit antenna array is combined with a coherent FM-CW architecture. It permits two dimensional electronic scanning in range and cross range with excellent crass range resolution over a wide angle of new using very low EIRP. The advantage of using such radar is that it requires just a small number of active millimeter wave components. [9] Novel Photonic Rotman-Lens Design for Radar Phased Array Antennas A new microwave photonic implementation of a Rotman-lens is proposed in this project, providing superior performance and functionality. The scanning unit presented is an optical element, where photo-detectors attached to the transmitting/receiving antennas are the interfaces, doing conversions among the RF signals and their particular optical waves. Actually, the optical module is a photonic Rotman lens, designed like its RF complement. Despite the advance of practicing the solution in a photonic module, the recommended photonic Rotman lens superior design is able to realise a linear phase profile with a varied slope at the output of the lens for any potential spot at the input to the lens. This is contrary to what is presently accessible with the usual RF Rotman lens, where output phase front linearity is achieved for a small quantity of input spots. A better performance is achieved by increasing the curves of the photonic input and output surfaces of the lens, having an off-centere d elliptical profile, and not the typically used spherical curvatures. [10] Virtual Antenna Beamforming (VAB) for Radar Systems by Using Orthogonal Coding Waveforms An original way of creating virtual transmitting and receiving radar antenna beams at the same time is to use orthogonal coding waveforms from the antenna elements and deal out digitally their echoes at the receiver. Many virtual transmitting-receiving radar antenna beams can be produced at the same time by using the same quantity of beamforming filters with no any increase on the transmitted power or antenna gain or resolution loss. Both virtually formed antenna beams and common phased arrays of equal size are able to achieve the same antenna gains and spatial resolutions. Since the antenna radiation pattern can be completed almost isotropic, the original system has low probability of intercept (LPI) property. While the transmitting and receiving beams are both virtually implemented through digital filtering, expensive radiation phase shift used in phased arrays is unnecessary for beam scanning in this actual system. [11] Compact Two-Layer Rotman Lens-Fed Microstrip Antenna Array at 24 GHz A new way of realizing a compact Rotman lens-fed antenna array is presented in this paper. The lens-fed antenna has the construction of two layers, which is an original option of reducing the Rotman lens size. This is performed at 24 GHz approaching automotive sensing radar. The lens has a metal layer on the top, a dielectric, a regular ground, a dielectric, and a metal layer on the bottom, in sequential order. The antennas are put on the top layer, while the layout of the lens body is positioned on the bottom layer. They are both connected electrically via slot transitions. This structure, composed of two layers, offers many advantages, because it reduces the entire size of the lens, as well as the total loss of the delay lines, as the lines can be as short and straight as possible. This two-layer Rotman lens-fed antenna array is evaluated in terms of scattering parameters and beam patterns. [12] Cylindrical arrays with electronic beam scanning In order to provide a continuously 360 degrees scan by the directional pattern of a cylindrical array using electronic means, there are several methods proposed. It is important that the circular aperture distribution related to the far-field directional pattern is subjected to rotation comparative to the fixed array. With the intention of synthesizing appropriate forms of directional pattern, there are various techniques describing the independent control of the amplitude and phase of the aperture distributio

Typology Of Organisation And Relation To Servicescape Complexity Business Essay

Typology Of Organisation And Relation To Servicescape Complexity Business Essay The following essay critically analyses the strategic role that physical evidences play in a holistic environment, called the servicescape. The essay discusses the combination of environmental dimensions and their influence on customers and employees and how their behaviour can be mediated by the cognitive, emotional and physiological responses. This article is a practical reflection on the article by Ms. Mary Jo Bitner in which she related the combination of environmental dimensions to the internal responses of individuals, their behaviour and the ultimate effect on the organisational objectives. The researcher also visited two restaurants for the objective of completing this essay and the findings have been presented here under. This essay will conclude by defining different ways in which the effects of a servicescape are established on the organisations outcomes. Servicescape Framework Initially, Kotler (1974) suggested that a servicescape framework is the design of buying environments to produce emotional effects in the buyer that enhance his or her purchase probability. Later, Bitner used the term to describe the physical setting in which a commercial exchange is performed, delivered, and consumed within a service organisation. In her seminal article, she demonstrated that three types of objective and measurable physical stimuli exist in an organisation and merge together to form a servicescape. She further elaborated that these stimuli could be controlled by the organisation and were able to improve or hamper both the customers and employees attitude towards the organisation. She further classified the numerous examples of such physical and derived stimuli into three dimensions of environmental stimuli (Bitner, 1992). The term has now been enhanced to include any tangible component that facilitates performance or communicates the service (Bitner and Zeithaml, 2 003). Consequently, the physical evidence can be likened to a landscape. As with any landscape of an area, it includes both the interior facilities and the exterior facilities of the organisation. The interior facilities include the interior design and decoration, the layout, equipment, air quality, signage as well as the temperature and ambience. The exterior would include facilities such as the landscape, parking, road and building signage, exterior design, and the surroundings. But the physical evidence goes on to include other tangibles such as the Stationery, brochures, business cards, employee uniforms, business reports, credit statements, and other intangibles such as webpages and blog posts. The physical environment where services are delivered and experienced by the customers plays an important part in the formation of the perceptions of the customers and their future expectations about similar services (Bitner, 1992; Baker et al., 2002; Grewal et al., 2003). Hoffman and Turley (2002) described that a lot of different organisational objectives can be achieved and enhanced through a critical examination of the servicescape. According to Bitner (1992), most organisations are invariably affected by their physical environments but to different degrees. Some service organisations such as hotels, restaurants, clubs and insurance companies are affected to a greater extent by the physical environment than other organisations such as ATMs and hot dog stands. It should be noted here that the physical environment does not just influence clients but it also has a significant impact on the employees. Bitner noted that satisfied employees generate satisfactory services that go on to satisfy customers. Therefore, the business environment should not only cater to the needs and demands of the customers but also concurrently to those of the employees. The following figure has been extracted from the original treatise by Ms. Mary Jo Bitner (1992) to describe the different types of service organisations based on the variation in the form in usage of the servicescape. The vertical aspect of the typology describes the type of organisation based on who performs actions within the servicescape. It has been categorised into a self service (customer only), interpersonal services (both customer and employee) and remote service (employee only). On one side, service is performed by the customer only in the level of employee activity is almost non-existent. The other extreme is signified by the remote service organisations where customer involvement and interaction are non-significant (in relation to the servicescape). The figure, the horizontal aspect describes the complexity of the servicescape. It has also been categorised as lean and elaborate. Lee refers to those servicescape settings where there are very few elements involved and their intricacy is minimal. Other servicescapes that are very complicated and involve a bigger mix of elements and variables are termed as elaborate. C:UsersKhalidDesktopo_c44bab260d23dc1e_002.jpg Fig. 1: Typology of Organisation and Relation to Servicescape Complexity As can be seen, some organisations such as a Golf Club are very client-oriented with huge emphasis on the servicescape. In such organisations, the servicescapes are well-developed to attract and satisfy customers. Other organisations also employing a significant emphasis on the servicescape at which are employee oriented include many professional services organisations, and here, the servicescapes are developed to satisfy the employees. On the other hand, there are organisations that do not depend a lot on the servicescape design and minimal effort is dedicated to the development of their servicescapes. However, attention is paid to whether the organisation is customer oriented or employee oriented to achieve maximum output from invested effort. As has been described, the physical setting can enhance or hinder the realization of both internal organisational objectives and external marketing goals. Thus, the servicescape can enhance or diminish customer satisfaction and employee motivation and concurrently help in attracting and maintaining customers. The overall servicescape framework consists of physical environmental dimensions which contribute to the holistic environment of the organisation. These physical dimensions, in combination, are termed as the perceived servicescape of the organisation and elicit internal responses from both employees and the customers. These internal responses contribute to both the individual behaviour of the customers and employees and their social interactions. These behaviours, in turn, contribute to the achievement of the objectives and goals of the organisation. Thus, organisations focus on achieving an optimal mix of physical environment factors and try to moderate the internal responses of both employees and customers to realize favourable behaviours and ultimately achieve the organisational objectives. Untitled.png Fig. 2: Bitners Servicescape Model The Physical Environmental Dimensions Bitner (1992) classify the physical environment into three dimensions: Ambient Conditions: This aspect of the physical environment refers to the conditions surrounding employees and customers that can be sensed through the human five senses. These are the general conditions of the environment of the organisation and include temperature, voice, odour, air quality, et cetera. The conditions are usually prominent when they are extreme (either very cold or hot), the customer spends a lot of time in the environment, and they do not match his expectations. Spatial Layout And Functionality: These refer to the seamless layout of the organisation, especially equipment and furnishing, which is used to achieve maximum productivity in the most efficient and effective manner. These environmental conditions are most noticeable in self service settings and in circumstances where tasks are complex and there is little time to achieve them. Signs, Symbols, Artefacts And Branding: These refer to the signage, icons and signals that amplify the message from the organisation to the intended customers. They also include the personal artefacts of the employees and staff members in the style and colour of the decor used to furnish the organisation. These are most important when repositioning a service, forming first impression, and when communicating new service ideas. They are also highly essential in highly competitive organisations where they are used to differentiate and achieve uniqueness from the competition. Internal Responses to the Servicescape Internal responses of both employees and customers in service organisations to the physical dimensions of the surroundings are classified as cognitive, emotional, and physiological. As such, these responses elicit overall behaviour of the participants in the servicescape and this behaviour can be classified as a function of the internal responses to the perceived servicescape. In fact, perceptions of the servicescape are the real reason that causes certain beliefs, emotions and physiological feelings that influence behaviours. Cognitive responses: Cognition refers to beliefs and as such, these responses influence peoples beliefs both about the place, and the people and products found in that place. These responses include general beliefs, categorisations and assigning symbolic meanings to different objects to employees and customers. Emotional responses: According to Mehrabian and Russell, the emotion-eliciting qualities of an environment can be described along two dimensions; the pleasure-displeasure quality and the degree of arousal that place can elicit. These two dimensions describe peoples emotional response to the environment of the organisation. Typically, the environment of any organisation can be located on these two dimensions. Research has shown that predictions about behaviour along these two dimensions are usually accurate. For example, environments that make people happy and cause them to enjoy themselves are likely to be places where people spend most of their time and money. In contrast, people usually avoid places that cause feelings of displeasure. Similarly, environments that cause arousal will usually be the places that people usually inhabit. Physiological responses:

The Healing Power of Poetry Essay -- Writing Essays

"The Healing Power of Poetry" The devastations and repercussions of war are inimitable, and can sometimes be left unhealed. However, men and women have had to find cures to lick their wounds and resettle the turbulence existing within their minds. In Pat Barker's emotionally powerful war novel Regeneration, we are introduced to a war journal, called the Hydra, on page 84, which served as healing tool for WWI soldiers. This journal contained articles, cartoons, poetry, letters, and all kinds of other different types of writing. Barker uses the Hydra in her novel to mark the healing power of writing in the lives of these men. Poetry therapy has a long history, being recognized as far back as the first songs chanted around the camp-fires of primitive people. To these people, the chant is what heals the heart and soul. In the English language, the word "therapy" comes from the Greek word "therapeia," which means to nurse or cure through expressive arts such as dance, song, poem and drama. The Greeks have also informed us that Asclepius, the god of healing, was the son of Apollo, the god of poetry, medicine and the historical arts (Longo). In addition, mythological beliefs say that Oceanus told Promethus that "words are the physician of the mind diseased." The use of poetry therapy has therefore been discovered by numerous cultures since the beginning of language (Longo). Once recognized for its healing power, this therapy quickly moved to the North American continent. Within the American colonies, the first American hospital to care for the mentally ill was founded in 1751 by Benjamin Franklin, called the Pennsylvania Hospital. This hospital is known to have included reading, writing, and then also the actual publishing of... ...f writing to these men. Not only does it convey the effects of writing, it may also project the idea that reading poetry may also be just as therapeutic. Poetry therapy is not a theme that people would generally relate to the cure of barbaric men at war, which is indeed what makes this novel so brilliant. Soldiers too have a sensitive side, and Barker has proven to acknowledge and praise it. Works Cited Barker, Pat. Regeneration. New York: Plume, 1993. Lee, Stuart. "The Hydra."

Feminism in Pop Culture

Many myths and misconceptions float around the term ‘Feminism’. It is a movement that is frequently projected as being violent, aggressive, and full of ‘bra burning’ extremists. The word alone often evokes reactions among people that are negative, uncomplimentary and stereotypical. The disturbing of the patriarchal paradigm was a phenomenon that became prominent only in the Twentieth Century. Historically speaking women have always numerically outnumbered men, but through the system of patriarchy they have been suppressed by political, economic and social machinery. The difference between Gender and Sex When trying to examine feminism we must keep in mind the subtle difference between ‘gender’ and ‘sex’. For example, if a man were to dress or behave like a woman, it would not change the fact that he is still biologically a man, and here is where the difference lies. When we use the term ‘gender’, we are referring to a social construct, a store knowledge that has developed over generations that helps us in our identification of a person as a man or a woman. A person’s sex on the other hand is purely biological. A primary argument of feminist theory is that arbitrary allocations such as this that are constructs of society are completely devoid of any genuine value. Thus the duty of feminism, in one sense, involves the subversion of existing patriarchal paradigms by questioning phallocentric, or penis-centred, sources of power. Patriarchy and the Woman The term ‘Patriarchy’ itself can be broadly defined as an ideological system of belief that privileges males over females. This is a complex system that employs androcentric values, rituals and practices in order to maintain status quo. Another means of control involves patriarchy passing itself off as the so-called ‘norm’ or the ‘right’ way in which a society must divide itself, and regards the Female as a departure from this ‘norm’ and treats her as ‘the other’, a notion that only reinforces the sharp cleavage between the two sexes. As a result of this treatment, the decisions of a society are based on whatever the man decides, whereas everything else is lumped together as ‘the other’, the Female. It is however ironic that patriarchy itself requires the co-operation of the Female in order to subjugate her, making her a willing participant in her own suppression. As the French feminist Simone de Beauvoir put it so aptly in her seminal book, ‘The Second Sex’, published in 1949, ‘One is not born, but rather becomes a woman. ’, a statement that raises our consciousness to the disparity between the male ‘norm’ and the female ‘other’. It was indeed French Feminism that first brought to light the fact that all western languages are irredeemably male-engendered, male constituted and male-dominated. Discourse itself is phallocentric as seen in its vocabulary, syntax, rules of logic and its tendency for classification and opposition as well as the need for objective knowledge. Definitions of Feminist Literary Criticism There are multiple definitions that can be applied to Feminist Literary criticism. It differs from other schools of critical theory in that it does not derive its literary principles from a single authoritative figure or from a body of sacred texts. This is quite unlike other approaches such as Psychoanalysis, Marxism or Deconstruction, which can all be attributed to their primary exponents, Freud, Marx and Derrida respectively. Feminist theory has evolved from several sources, with several feminist thinkers contributing to the canon. Moreover, critical theory used in readings of Woman’s literature borrows from other disciplines such as History, Anthropology, Linguistics, Psychoanalysis and Marxism. It was a form of criticism created by literary and academic women who participated in the women’s liberation movement in the late 1960s. Kate Millet’s book, ‘Sexual Politics’ (1870) was the first major treatise on feminist criticism, and also represented a strong political argument for women’s rights. The Dictionary of Concepts in Literary Criticism and Theory defines Feminist Criticism as ‘The understanding and analysis of and response to literary works, and/or language and/or the institution of literary study or theory from the point of view of women’s experience. ’ â€Å"Feminist Criticism†, says Elaine Showalter, in her book ‘New Feminist Criticism’, â€Å"has established gender as a fundamental category of literary analysis. † Her article, ‘Dancing through the Minefield’ has also made some observations on the politics and practice of feminist criticism. She also points out that the earlier groups of feminist critics were preoccupied with the gender bias in writing, whereas the later group of gynocritics studied women as writers. Another columnist, Annette Kolodny, defines feminist criticism as â€Å"An acute and impassioned attentiveness to the ways in which primarily male structures of power are encoded within our literary inheritance, and the consequences of that encoding for women†¦ not only for a better understanding of the past but also for an improved recording of the present and the future. This form of criticism, as a self-aware and concerted approach to literature came into being in the late 1960s, as a part of the international woman’s movement. One of the first areas it looked into and challenged was literature, where it was always assumed that the representative reader, writer and critic were all male. The historical background and watershed marks in Feminist Criticism Behind the movement in the 1960s, however, lay two centuries of struggle, represented only by a few texts such as Mary Wollstonecraft’s ‘The vindication of the Rights of Women’ (1792). A later book, this time by John Stuart Mill, ‘The Subjection of Women’ (1869) was also brought to the fore. It suggested that the Wife was a family’s source of sustenance, and therefore the empowerment of the generations could be achieved only by empowering The Woman. The next seminal work in Feminist Criticism was penned by Virginia Woolf in 1929. Called ‘A Room of One’s Own’, the book talked about the major directions in which feminist explorations of literature needed to develop. The book is rich with insights about the absence of women writers and readers, and the probable fate to which the hypothetical ‘Sister of Shakespeare’, blessed with equal or greater genius, would have been consigned to thanks to socio-cultural obstacles of the age. In it, Woolf’s contention is that ‘A woman must have money and a room (referring to space, privilege and opportunity) of her own if she is to write [fiction]. † Other significant books include Toril Moi’s ‘Sexual/Textual Politics’ (1985) and Sandra Gilbert and Susan Gubar’s ‘No Mans Land: The Place of the Woman Writer in the 20th Century’. These texts introduced the principles of feminist literary theory to the world. Their purpose was to offer feminist readings of texts that looked at the images and the stereotypes of women in literature as well as the omissions and misconceptions about women in criticism and ‘women-as-sign’ in semiotic systems. This kind of criticism concerns itself with developing a specifically female framework for dealing with works written by women, in all aspects of their production, including analysis and interpretation in ll literary forms and expressions, including journalism and popular culture, like Patricia Mayers-Spack’s ‘The Female Imagination’, Ellen Moer’s ‘Literary Women’, Elaine Showalter’s ‘A Literature of their Own: British Women Novelists from Bronte to Lessing’, or Gilbert and Gubar’s ‘The Mad Woman in the Attic’, a reference to Bertha Mason, who is ‘usually in some sense the author ’s double, (the other) an image of her own anxiety and rage. ’ Through the women’ liberation movement, literary criticism drew a connection between the lived lives of thousands of women who studied and taught literature. An important area of research was the limited secondary roles of fictional heroines and other feminine stereotypes in canonical literature. The Role of Feminist Criticism Feminist criticism, developing in tandem with the women’s liberation movement brought in a dual perspective that brought about a reappraisal of texts, looked at the construction of gender through language and the gendering of text, and examined the representation of women in literature and the exclusion of women as fictional characters, authors and readers. As far as literature is concerned, the role of Feminist criticism was to look at canonical literary works and the manner in which they represent women as stereotypes, and to develop theories for sexual differences in reading, writing and literary interpretation. It brings to the fore and establishes ‘gender’ as a fundamental category of literary analysis, and takes into account the fact that the vast majority of what is conceded to be the ‘literary canon’ is by and large authored by men, based on masculine norms and values, and women’s writing therefore is either excluded or undervalued in canonical literature, criticism and theory. Feminist critics also look at the representation of female experiences in literature. They reason that because a major aspect of literature is the reporting of our biological sense experiences, it would be impossible for the male to authentically capture an entirely feminine experience such as menstruation or childbirth. Feminist criticism also bases itself on two other primary assumptions: That gender is constructed through language (by way of political incorrect words and phrases such as ‘chairman’, ‘male nurse’ or ‘actor and actress’), and that writing strategies are sex-related and therefore misogynistic. Feminist criticism also shows that women readers, critics and writers bring different perceptions and expectations to their literary experiences, and insist that women have important stories to tell of their own culture. This kind of criticism opened space that now extended beyond the study of only women writers and now included the reappraisal of all literature that makes up our heritage. Feminist critics look at literary representation of sexual differences, and how literature shapes masculine and feminine values, privileging one set over another. The aim of feminist criticism therefore becomes to re-examine male texts, emphasize writing by women by charting a new literary history that includes neglected texts, a female tradition created by a sub-community of women writers who found support from their literary foremothers and so become role models for younger female writers. They also look at the oral tradition and other extra-literary expressions. Another aim involves the creation of new reading and writing collectives, libraries, publishing houses, social centres, colleges and so on. Feminist criticism confronts the problem of the feminist reader by offering new methods and fresh critical evaluation of issues, such as the mother-daughter cultural and relational aspect. Another major concern of Gynocritics is to identify what is taken to be distinctly feminine subject matter in literature written by women, the idea of sisterhood and female bonding, domesticity, gestation, birth, motherhood, mother-daughter or woman-woman relationships, etc. They also undertake to show that there is a distinctive feminine mode of experience or subjectivity in thinking, feeling, valuing and perceiving the self and others. French Feminism Related to this is the specification of the traits of women’s language and its distinctive style of speech and writing. Women must write in a way in which they can avoid the pitfalls of phallocentric language mentioned earlier, in a style represented by the term ‘ecriture feminine’ or writing in the feminine, a concept that was a product of French feminism. Helene Cixous, its main exponent, credited with authoring its manifesto, ‘The Laugh of Medusa’ (1975), stated that ecriture feminine is to be found in metaphors of female sexuality and women’s libidinal differences. Another critic, Luce Irigary, talks about women’s writing and its evasion of the male monopoly by replacing the monolithic phallus by the diversity, fluidity and multiple possibilities represented by female sexuality. These critics believe that women must try to resurrect the ‘feminine-feminine’ which possibly lies in the unconscious of all women. Julia Kristeva speaks of a pre-natal, pre-linguistic, pre-oedipal and unsystematic signifying language between the mother and the infant centred on the mother that she labels as semiotic and abstract, as opposed to the symbolic or letter based language of the father. Semiotic writing disrupts phallocentric writing because it is free from oppressive order and rationality. Both men and women can write in this mode, which deconstructs masculine structures of knowledge and attacks patriarchy and its language. The overall aim of ecriture feminine is therefore to allow a woman to write of, from and about their bodies. French feminist theory has contributed significantly to feminist literary criticism by studying the relationship between women, psychology and language. Currently feminist criticism employs a wide range of approaches and addresses a variety of issues of feminist interest. This is called ‘Playful Pluralism’. The oft-asserted goal of feminist critics has been to enlarge and re-order, or in some cases entirely displace the (patriarchal) literary canon. Feminist studies have served to raise the stakes of many female authors who were erstwhile neglected or even overlooked.

Brave New World & “Bokanovsky’s Process”

The conflict between individuality and communal identity forms a central theme of Huxley's Brave New World. From the opening page of the novel, it is clear that Huxley's satirical utopia is supported by an over-riding sense of civic authority and communal identity. The World State celebrates its law and ethical paradigms by way of sloganism and its herald: â€Å"†in a shield, the World State's motto, COMMUNITY, IDENTITY, STABILITY†; the three words in rapid succession suggest that the religious trinity of Father-Son-Holy-Ghost have been replaced by communal identification.The words seem to lead into one-another, blurring their meanings together and suggesting a cause and effect: that â€Å"community† allows for â€Å"identity† and â€Å"stability†; community in the World State, in fact, is identity and stability, (Huxley). As the novel's first extended scene gets underway, the reader begins to enter the utopian world and realizes that individuality, as recognized by contemporary real-world readers, is placed at a very low priority in the World State. The mass-production of cars and other factory-built products has been applied to human beings.Students attend a medical lecture on the â€Å"Bokanovsky's Process† which generates mass-human production: One egg, one embryo, one adult-normality. But a bokanovskified egg will bud, will proliferate, will divide. From eight to ninety-six buds, and every bud will grow into a perfectly formed embryo, and every embryo into a full-sized adult. Making ninety-six human beings grow where only one grew before. Progress. (Huxley) From the very beginning of life in the World State, individuality is sacrificed in the name of community and in the name of progress.Huxley's satirical inversion of the associations most commonly associated with human infants: those of possibility and uniqueness and joy and subsumed beneath his Ford-factory-utopian abstraction of babies born in labs on conveyer b elts. With this single image and scene, Huxley sets up the central dichotomy of Brave New World, the conflict between individual liberty and self-actualization and communal of State-controlled power and State mandated â€Å"happiness.† Because Huxley's intention is to critique the â€Å"inhumanity† of man, his vision of the complete eradication of individuality, by necessity, must begin at birth. The coldly biological and assembly-line imagery establishes the depth and breadth of the conflict between individuality and community identification with urgency and immediacy. To further extend the comprehensiveness of the conflict, Huxley must demonstrate the loss of individual sexual impulse and reproductive rights right along with his vision of the State run assembly-line incubators.To completely subsume individuality, it is necessary to demystify eroticism and sexual acts: sex is permitted freely in the World State although the kind of sex which is depicted is cold and un feeling and not at all what one would associate with human sexual impulse and romantic relationships as we now know them. Because human sexuality begins with self-image, Huxley's depiction of Lenina's grooming and dressing routine plays a key role in showing how individuality is eradicated by the Stare sponsored eroticism and fashion: â€Å"Lenina got out of the bath, toweled herself dry, took hold of a long flexible tube plugged into the wall[†¦] A blast of warmed air dusted her with the finest talcum powder. Eight different scents and eau-de-Cologne were laid on in little taps over the wash-basin. † Because Lenina is later revealed to harbor serious radical thoughts regarding sexuality and love, the preceding scene of her bath and dressing serves to show how her inborn beauty and natural sexuality have been obscured beneath synthetic-ism and communal homogeny, (Huxley).Lenina's desired state of sexuality is in stark conflict with the professed sexual morals of the Worl d State where past ideas about love, sex, and romance are vilified and seen as limitations to true human expression: â€Å"Family, monogamy, romance. Everywhere exclusiveness, a narrow channelling of impulse and energy†; in the new, progressive society, â€Å"every one belongs to every one else,† and there is no such thing as individual love or romance or monogamy.This inversion of sexual permissiveness — like Huxley's conflation of assembly-lines and nurseries — is an ironic technique which is meant to signal the perils of the breakdown of individuality and spontaneous :chemistry† between people. Huxley is saying, in effect, that is human individuality is sacrificed in the name of progress, then true progress will also have been sacrificed altogether. By demonstrating the grotesque nature of State sponsored Eros and State sponsored births, Huxley attacks the core-experiences of humanity and sets his satirical sights on clarifying through horror, th e grave importance of individuation in society.In response to the axiom that â€Å"everyone belongs to everyone† and thus has no personal will whatsoever, the young students in the lecture merely accept this axiom as truth: â€Å"The students nodded, emphatically agreeing with a statement which upwards of sixty-two thousand repetitions in the dark had made them accept, not merely as true, but as axiomatic, self-evident, utterly indisputable,† and with his observation, Huxley makes it clear that the stifling of individuality leads to a stifling of the mind, the imagination, and the will to discover truth as opposed to convenient but possibly corrupt or false explanations, (Huxley)If borth adn reproduction play a very large role in the fundamental elements of Huxley's satirical examination of the conflict between individuality adn community in Brave New World, the issue of death — and more specifically of grieving — play an equally important role in present ing a Utopian nightmare where the basic attributes and experiences of humanity have been paved over by homogenized experience and unemotional interpersonal relationships. A good example of this sub-theme in the novel is the scene between the Savage and the nurse in the hospital when the Savage's mother lies dying.Normal grieving is looked at as a deep weakness in the social order of the World State: â€Å"Startled by the expression of distress on his pale face, she suddenly broke off. â€Å"Why, whatever is the matter? † she asked. She was not accustomed to this kind of thing in visitors. (Not that there were many visitors anyhow: or any reason why there should be many visitors. ) â€Å"You're not feeling ill, are you? † He shook his head. â€Å"She's my mother,† he said in a scarcely audible voice. The nurse glanced at him with startled, horrified eyes; then quickly looked away. (Huxley).Huxley's novel is satirical in essence, but it is horrifying in experienc e and the strength of its visceral message about the urgency of preserving individuality is in many ways made acutely powerful by Huxley's satirical inversion of primary modes of human experience including: birth, love, sex, friendship, self-image, and even death. By demonstrating the horror of utopia through the loss of personal individuality, Huxley adroitly satirizes many of the conventions and technologies which have steadily risen as a threat in society to the sanctity of the individual.
