Individuality in 1984 essays

Individuality in 1984 essays In the end the party would announce that two and two made five, and you would have to believe it. It was inevitable that they should make the claim sooner or later: the logic of their position demanded it. Not merely the validity of experience, but the very existence of external reality was tacitly defined by their philosophy. The heresy of heresies was common sense. And what was terrifying was not that they would kill you for thinking otherwise, but that they might be right. For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable-what then?" Freedom is individuality, and individuality is freedom. The denial of the rights to think and act upon unique thoughts is the basis of the partys power to control the mindless masses of Oceania in George Orwells hellish vision of 1984. In this passage, Orwell reveals his fear of the distinct possibility of the complete loss of individuality in modern society. Through the control of thought and stripping of human emotion, the party is able to abolish all diverse thought and action to ensure a stable environment robbed of all human dignity. And what was terrifying was not that they would kill you for thinking otherwise, but that they might be right. This forms the basis of Orwells fears of mind control. He illustrates here the partys ability to completely brainwash an entire society. If a single body can create a society in which every one of its members believes something that is not true, they are capable of anything. If facts are alterable in an instant, and lies can become truth, than opinions can be manipulated even easier. Individuality is the complexity and variation of thought, but the party values single-mindedness and ignorance. The people of Oceania are all conditioned ...

Priority Health Issue Report and Critical Analysis of Health Promotion Essay

Priority Health Issue Report and Critical Analysis of Health Promotion Initiatives - Essay Example Third is through the use of a priority area to be determined by examining the cost to individuals and the community. A higher cost will imply a higher level of prevalence (Diabetes Australia & Australian Diabetes Society, 1988). Potential to change is also a method that may be used. Having evaluated the health status of the country, the government has pinpointed the following health priority issues. First are the groups that are currently experiencing some forms of health inequities. Second are the rapidly increasing levels of preventable chronic diseases such as mental complications, cardiovascular diseases, permanent disability and increased mortality rate. Third are the growing and the ageing population, as Australia’s life expectancy rate continues to increase. The Australian health care system has made great contributions in the improvement and maintenance of good health status for the Australians. The healthcare system works with the government to fund the healthcare of public and private bodies. This is in addition to rehabilitation, treatment and diagnosis systems. The system has also extended its cover to all citizens and people can now participate in private health insurance to extend their healthcare coverage. Australia’s healthcare system has also focused on improve technology to better their services to the people. To improve the health status, the Australian healthcare system in collaboration with the federal government has put in place professional and regulatory associations that look on the credibility and applicability of the laid down healthcare approaches and their benefit to the public (Scoggins, RAND Europe, & Rand Corporation, 2008). To address Australia’s health priorities, various actions will be of great importance. First is the use of the public health approach through what has been defined as

Morocco Country Risk Assessment Essay Example | Topics and Well Written Essays - 1000 words

Morocco Country Risk Assessment - Essay Example Having been inhabited back in the Paleolithic times, most of the citizens are either Arabs or Berbers with the latter ethnic group forming the bulk of the population. Other ethnic groups that form part of the population include Haratin and Gnaoua. Additionally, the country is inhibited by more that 100,000 foreigners including Spanish and French who have invested in various sectors thus improving the country economic performance. Culturally, Morocco is known for being an ethnically diverse nation based on its hosting various foreigners who come from the East, South and other regions. Some of the key visitors who have contributed to the cultural growth of the country include Carthaginians, Arabs, Phoenicians, Romans, Andalusians, Jews and Vandals among others. Due to the interaction of the various groups in the country, Moroccan literature has continued to experience an expansive growth. For example, western and Middle East literary models have enhanced the growth of poetry and tradit ional Moroccan genres (Yahya 49). Similarly, the country rich cultural values have attracted expatriates academic and social writers such as Paul Bowles and Pierre Loti among others. Infrastructure One of the major factors that make Morocco a good country for investors is the highly developed infrastructure system as compared to other African countries. For instance, the country is served by more that 35, 946 miles and 18,800 miles of primary roads and secondary roads respectively. As a result, the cost of transporting raw materials and finished products within the country is low thus resulting to high profits by the local and foreign investors. Additionally, the government has continued to issues large number of licenses to... This paper stresses that a vital factor that makes Morocco a viable country for investors is the electrical power development. National Office of Electricity is the main government-owned firm that is responsible for providing electricity power in the country. Even though the country has significant oil reserves, most of the power was earlier generated from imported fuels from Saudi Arabia. This report makes a conclusion that Morocco is ruled under the constitutional monarchy with the prime minister holding major powers while the king hold few executive powers including dissolving the parliament. Two major chambers in Morocco parliament are the assembly of councilors and the assembly of representatives. To ensure justice in the country judicial system, the country constitution provides for an independent judiciary. In this way, politicians do not have much impact on the country court system thus reducing the level of corruption in the country. One of the remarkable political initiatives that occurred in 2011 was the drafting of new constitution that brought about major reforms in the country political system. For example, the king was given power to appoint a prime minister from the party with the majority seats in parliament. Similarly, the prime minister was given power to appoint high level diplomats and chief executive officers of the government owned organizations. It is worth noting that the constitutional also gave power to all citizens by ensuring freedom of creation, ideas, thought among others.

Wooden Bat or Metal Bat Essay Example | Topics and Well Written Essays - 250 words

Wooden Bat or Metal Bat - Essay Example Using a wooden bat or a metal one has always been a controversial issue for baseball players. Wooden versus metal bat debate is not new for baseball fans who love to discuss what kind of bat is suitable for a bigger hit. This paper compares and contrasts the two types of bats. Wooden bats are heavier than metal because they are solid. Metal bats are hollow from within. Wooden bats require more effort to sway than metal oness. They also have a smaller sweet spot (Zumerchik 52) due to which the hit remains within range. Metal bats are lighter because of larger sweet spot which makes the hit swing higher. Wooden bats are safer than metal because the exit speed of the ball from a wooden bat is much slower. Thus, the ball comes off with slow speed, which is good, for it reduces the danger of injury if another player or pitcher hits the ball. Metal bats, as they are lighter, can easily get tossed away to injure another player. A wooden bat, due to its solid mass, does not compress when the ball hits it. But when the ball hits a metal bat, it causes the latter to compress which has a negative effect on the exit speed of the ball, though the exit speed is enhanced by the center of gravity being placed near the handle. In wooden bats, there is no issue of compression. To conclude, wooden bats are heavier, safer, and are affordable in price. Metal counterparts provide larger hit zone, are lighter and easy to handle. Major League Baseball makes the players use wooden bats due to their certain advantages over metal equivalents.

Simulation Of Inmarsat C Channels Using Matlab

Simulation Of Inmarsat C Channels Using Matlab This report is all about Inmarsat-c channels its standards and simulation of C channels using matlab. The use of satellites for control, command, communications and navigation is an area of high end technology which has grown significantly over the last decade and been primarily dominated by the military. The establishment of mobile satellites is offering services to the public and commercial fleet operators the opportunity to take advantage of these developments. This communication channel implements Global Maritime Distress and Safety System and data transfer functions between INMARSAT-C compatible terminal and a land earth station. Compatible software, installed on embedded system controller is used for simulation of Inmarsat terminal. This controller transfer data to simulated Inmarsat satellite using a wireless transmission network. The satellite functions are implemented into another embedded system controller. This satellite communication controller is linked with Inmarsat ter minal via wireless transmission network and with another land earth station using a secondary wireless channel. The land earth station is software implemented in a PC linked with simulated satellite using a wireless network. This center is able to manage messages received from Inmarsat terminal, via simulated satellite, and convert them into short text messages, automatically delivered to local network workstations, in faxes format or mail messages. The system can be consists as base for a GMDSS simulator. 2. INTRODUCTION Inmarsat is an international organization which works for the satellite system for the support of mobile communication system. Another major function performed by this organization is radio determination services. The organization provides this radio determination service through out the world according to the necessity of certain area in the whole world. The organization was established in 1979 and now comprises 56 member countries and since 1982 it has operated a global network of L-band satellites. These services were earlier provided for ships, then the after certain time passed and new technology grew this service was also provided for the aircraft and now, according to the recent convention the land users of mobile can also get the service throughout the world. In the report software algorithms for the inmarsat C channels modulators and demodulators is discussed. Normally Sophisticated algorithms, including a fast Fourier transform (FFT)-based burst acquisition algorithm, carrier phase tracker, an innovative Doppler tracker, and acquisition symbol synchronizer, are developed and extensively simulated for reliable burst reception. The compact digital signal processor (DSP)-based demodulator hardware uses a unique personal computer test interface for downloading test data files. Inmarsat provides services according to established international standards which enables the mobile to roam and operate throughout the world. But the criterion is the international licensing requirements should be strictly followed in the applicable regions. This thing is very beneficial for the user as the servicing terminal is global and the operating cost could be saved. Another important perspective regarding this service is for manufacturer point of view that manufacturers can build large market and great number of users and the production cost of equipment could be reduced to the minimum extent. The Inmarsat Standards System has placed its foundation stone into the land mobile communications. Equipment is now being produced by many manufacturers throughout the world to technical standards introduced by IMWRSAT. This does not slow up innovative design or applications but ensures that all manufacturers of equipment operate efficiently through the satellites and fixed earth stations which provide access from the mobile to public and private telecommunications networks. Pre-operational services started in 989 in the Atlantic Ocean and are being expanded to the Pacific in the latter part of the year. The system is giving the users and manufacturers and opportunity to experience with the system throughout most of the world prior to full global commercial service which would be used globally at very frequent rate. The actual range of Standard-C facilities includes two ways of storing the messages and forwarding the data messaging as short burst of data. Todays fleet operators are facing increasing competition and a plethora of legislation which regulates their industry. It has therefore become essential that the truck operator be able to maximize the utility of the vehicle and drivers hours while staying within the law. This requires careful real-time fleet management which is an area where recent developments in on-board computer systems, vehicle navigation system, personal computers, reliable mobile telecommunications and fleet management software now provide the operator with the required tools at an affordable price. Throughout the world, truck owners face the same problems in maximizing the earning potential of the vehicle whenever it is on the road. In same countries return loads are not allowed to be carried by foreign vehicles while in others, companies find it difficult to identify potential cargoes. While the former may take time to overcome, the latter is now being addressed in many countries with cargo brokers and clearing houses operating data bases which show what cargoes are available and their destination. With many trucks still being owner operated, services such as these are likely to assume even greater importance as competitive market forces increase. The mergence of reliable navigation and communications systems throughout the world is now making it feasible for the truck operator to implement real-time fleet management solutions which will significantly improve his efficiency and profitability in the 1990s. In particular, the introduction of mobile satellite communications will integrate the truck and office and make the truck an integral part of the companies manageable assets. 3. BASIC DETAILS Satellite is basically any object that revolves around a planet in an elliptical or circular orbit. Natural satellite of earth is moon. Else there are also the manmade artificial satellites orbiting around the earth. These satellites are very help full in resolving many issues and provide great technological benefits for human beings on the earth. The path which a satellite usually follows is called an orbit. In the orbit, the farthest away point from Earth is the apogee, and the closest point is the perigee. Artificial satellites generally are not mass produced. Most satellites are custom built to perform their intended functions. Exceptions include the GPS satellites and the Iridium satellites. Satellites need to have certain ways of communication with Earth. Satellite need to get information and transmit the information it collects. It can relay information sent to it to another site on Earth. This is generally done using some type of antenna. The information is transmitted using radio waves that move at the speed of light, this method allows for very fast communications. All satellites must have a means of storing and analyzing the data collected, and ways of controlling its various systems. The satellite subsystem that completes this role is called telemetry tracking and control. Telemetry Tracking and Control is the main part or central part of the satellite and its operating system. It stores every activity of the satellite and receives information from the ground station, takes care of any general thing the satellite needs to do Telemetry Tracking and Control is made up of three components: Telemetry, Tracking, and Control Every satellite needs a source of power Factors to consider are cost, durability, and effectiveness. Satellites use up a lot of electricity Some possible power sources for satellites include: Solar panels Batteries , Nuclear power and Heat generators 4. INMARSAT Since 1982 INMARSAT has been providing high quality service of direct dial telephony to the maritime community throughout the world, 24 hours a day. In February of this year British Airways began providing similar services to aircraft crossing the North Atlantic. By the end of 1989 aeronautical data and voice services will be available worldwide on many airlines for public calling and airline operational requirements. Following the mobile reallocation of the L-band spectrum in October 1987 an Extraordinary session of the INMRSAT Assembly in January 1989 approved further enhancement to INMRSATs convention to provide land mobile communication services. Now, with the start of pre-operational Standard service, is poised to bring the benefits of satellite communications to all land mobile users throughout the world who have reason to travel beyond cellular or F3R coverage. Today, INMARSAT is the only organization with a space segment role to provide land mobile satellite communication services throughout the world. It is therefore in a unique position to rapidly respond to the needs of user community and to provide services giving both public and private closed user group access. In anticipation of these recent developments INMARSAT has, during the past year conducted an extensive series of trials and demonstrations of a low cost data and messaging service. These took place in East and West Europe, Australia and North America, and conclusively showed that the INWRSAT Standard C system is externally reliable and suited for land mobile use under all types of conditions and in all terrains. 5. STANDARD SATTELITE COMMUNICATION SYSTEM The overall system design meets the goals of standardized system. Elements and details of this overall communication system described below 5.1. COMS At the remote site COMS is a low-power DC computer, INMARSAT-C radio, and independent power system in a single package. A message can be sent via INMARSAT-C to or from any device on the local-area network. COMS simply act as a filter, rejecting any packets that are not correct. GPS time messages are available from the INMARSAT- c radio, and COMS broadcast regular time packets onto the local area network. 5.2. Local Area Network. An EIA485 1ocal area network provides a simple digital communication link to elements of the ARCS. The LAN is reliable, low power, and noise immune. 5.3. MACS The monitor and control system is a low power DC computer, collection platform and independent power system in a single package. MACS collect hourly averaged scientific data from the DMS and utility data from the node data units then sends out the coded GOES data message. Monitor and control system can also send the same diagnostic data via INMARSAT if GOES is unavailable. It monitors van status and generates alarm messages. Monitor and control system has the ability to collect data sets from some instruments in the event the DMS is not operating. 5.4. DMS The data management system is the data collection workhorse for ARCS. It is a highly reliable implementation of a Sun workstation with copious tape recording capability. All elements of the DMs are redundant, including the processors. 5.5. NDu The node data units are small micro-power data collection devices that are placed in the network as required throughout the ARCS system. They perform monitor and control tasks on command and initiate certain alarm messages. One NDU is located in each sea container. 5.6. COMSAT COMSAT is a U.S. service provider for the INMARSAT satellite system. Messages can be transmitted to the ARCS in several different ways: (a) Direct transmission from an INMARSAT-c radio; (b) dial-up service to COMSAT; (c) Internet email service provided by COMSAT. 5.7. ARCS Base Station The ARCS communication base station is a multi-tasking computer that performs several tasks: (a) Monitor INMARSAT message traffic. (b) Provide an operator interface for sending control commands to the remote sites. (c) Routinely dial up and collect GOES data and forward them on to analysis sites. (d) Send alarm announcements when emergency messages are received. 6. STANDARD C SYSTEM The INMARSAT C system is the satellite system which usually provides two-way data communications from any place in the world. INMARSAT C terminals are very simple, cost effective and small in size to install any where at any point for example on vehicle ,air craft and easy to hand carry from one place to another place. Communications via the INMARSAT C system are usually data or could be message based. Any information that can be encoded into data bits could be transmitted using the INMARSAT C system. Any kind of Messages whether short or long are transferred from C terminal at information rate of 600 bits per sec. Frequencies are from 1626.5 MHz to 1645.5 MHz for the transmit, and 1530.0-1545.0 MHz for the receiving. C system is available in all four satellites of INMARSAT and its coverage area is from all oceans through 40 or more earth stations. A NCS in each region controls communications traffic. All INMARSAT maritime systems make use of 2-digit codes to facilitate transmission and reception of various types of maritime information. The typical INMARSAT C mobile earth station has a small omni-directional antenna. Antenna light weight and simplicity make it easily mounted on any place. Directional antennas are available which could be installed in fixed and movable modes. The main electronics unit is nearly 3 kg. Briefcase type terminals are available also and give benefit to international business travelers and field operators. Network architecture is shown below. Figure 1 . Network Architecture Some terminals have facility of built-in message preparation and display. Other terminals have serial port so that users can link their own personal computers or any other equipment for data transmission and reception. The power requirements of C terminals are good and can be easily achieved from battery and other resources. More than 100 different terminal models made by nearly 40 manufacturers are now approved to operate with C system. Communication system using a cost effective mobile earth station suitable for installation and use on any type and size of mobile platform. The system is providing two way messaging service and data communications on a store and forward strategy, one way position and data polling and enhanced group Call broadcast service able to address both groups and specific geographic areas. The system interconnects with both Public and Private Networks to provide International, Regional or National services. The store and forward feature enables the system to interconnect with any terrestrial message or data network. To keep the mobile equipment low costs and to minimize a very low G/T of -23dB/k at 50 elevations was selected to permit the use of a non-stabilized, unidirectional antenna. BPSK modulation is used and this coupled with the relatively low EIRP requirement of l2dBw can be achieved with a class HPA using existing semiconductors. To alleviate the effects of multi-path propagation on a very low gain antenna it was necessary to design a highly robust modulation and coding scheme. Transmissions frame the mobile take place between 1626.5 1646.5 M k and reception between 1530.0- 1545.0 MHz with tuning increments of 5 KHz. Standard C is therefore able to operate throughout all frequencies available on INMARSATs existing and next generation satellites which are already assigned for Land Mobile use. The narrow channel spacing also helps ensure maximum efficiency in the use of limited spectrum. The system has been designed with considerable flexibility in the access control and signaling protocols so that it can handle future new services and applications. The all digital design enables any type of data to be passed through the traffic channels due to the transparent nature of the transmission medium. Current INMARSAT satellites have global beams providing coverage of about 1/3 the earth surface and to satisfy the design link budget requires a relatively high satellite EIRP of 21dbW is used. Third generation satellites now being specified will have spot beams and the Standard C system will be able to automatically identify the appropriate beam. Because of the high power requirements the forward carriers operate in a demand assigned mode when network conditions require. In addition the store and forward mode ensures maximum loading of the carriers at any given time which results in a highly cost effective service and mode of operation. Network Coordination Station Each Satellite Network Region is served by an NJS which manages central resources such as traffic channels for demand assigned operation together with signaling and traffic control. Each NJS transmits a NJS communication signal which is received by all MESs when the message transfer is not occurring. The Communication Channel is used to announce calls to mobiles waiting at the LESS, for broadcasting E messages and at various stages for protocol signaling packet transfer. Land Earth Stations Each LES serves as a gateway between the ground network and INMARSAT Standard communications and network system. The different types of interface provided at the LES are decided by the earth station operator; however, Telex and E message processing are mandatory. All mobile earth stations that are active in the network region are required to register with the Key. The copy of the list of registered mobile earth stations are held at each LES and used as a reason for accepting or rejecting calls originating from the terrestrial network. In addition the location of every registered mobile earth station is held at the LES so that calls received at the LES for mobile earth stations that is on another ocean region can be redirected and the will call not be lost. Figure 2. SES Example 7. BENEFITS AND APPLICATIONS 7.1. ENHANCED GROUP CALL INMARSAT C terminals can receive multiple numbers of address messages known EGC. A specific header is inserted to the text to reference the group of mobiles and direct to the area for which the message is sent. Enhanced Group Calls can be transmitted in variety of languages and alphabets. There are two main types of Enhanced Group Calls: SafetyNET It provides an efficient and cost effective means of transmitting maritime safety and security information to vessels at sea and it is normally facilitated for different search and rescue coastguard co-ordination authorities. Short messages can be directed to mobiles and from mobile to any approaching specific regions. FleetNET It allows information to be sent to a virtually limitless number of mobile terminals simultaneously which are pre-designated. It is highly recommended for use by services specializing in the advertisement of news, reports and any other information regarding roads and ports. 7.2. SERVICES In bidirectional messaging INMARSAT C system can handle messages up to 32 kilo bytes in length. Every message from a mobile earth station is transmitted in data packets through satellite to a land earth station, where it is re-assembled and then sent to the final addressee via the local and international telecommunications networks. On the other side in the reverse direction callers can send messages to a single mobile earth station or to a group of mobile earth stations. 7.3. Data reporting and polling Many INMARSAT C system users need to acquire information from vehicles to cross-examine automatic data collection platforms at fixed or variable intervals. Data reporting allows the transmission of packets containing information of 32 bytes on request or on the base of pre-arranged intervals. On the other side polling allows the user base to interrogate a mobile earth station at any point of time, generating automatic transmission of the required information. 7.4. POSITION REPORTING INMARSAT C terminals can be connected with a wide range of navigation systems to provide a highly consistent, 24 hours position reporting capability. Position data can be derived from the earth based efficient systems and satellite based position fixing systems as global positioning system. 7.5. Distress alerting In the event of emergency threat alerting equipment gives the signal. The equipment is attached with Maritime INMARSAT C terminals. An emergency signal is automatically generated and information in distress alert signal contains position and any other information to a rescue coordination centre. 7.6. INTERNET EMAIL Most land earth stations offer internet electronic using the INMARSAT C service. 7.7. APPLICATIONS INMARSAT C is used in the road transports fishing boats, land mobile and aeronautical military aircraft, helicopters and also used by news agency members, international business travelers and people doing work for aid collection and for remote monitoring plus data collection. 8. STANDARD-C CHANNELS 8.1. General Different types of channels are used in INMARSAT standard C system. The channels are usually used not only in direct way communication from shore to ship but also inter-station links from shore to shore are used for network control process and monitoring. 8.2. NCS Common Channel The Network co-ordination station channel is a common channel which is time division multiplexed carrier transmitted continuously by the Network co-ordination station to all Satellite earth stations in the ocean region. Satellite earth stations tune to the Network control signal common channel when they are not operating. The channel operates on 1200 symbols per second with frame length of fixed standard of 8.64s. The information is encoded at half rate convolution and interleaved on a frame to frame base. Data rate is therefore 600 bits per seconds and all messages and signaling information is transferred in the form of packets. In each one of the frame total of 639 bytes are available for packets. The very first packet in each frame is board packet. After this packet number of signaling channel descriptor packets are transferred which are used to transfer information concerning satellite earth station usage of the signaling channels associated with that TDM carrier. 8.3. CES TDM Channel The forward link is used with the help of CES TDM channel when the CES is communicating with a satellite earth station. The structure of CES TDM is similar to the Network co-ordination station common channel described in details above, and is used for carrying out call set up signaling shore-to-ship message and acknowledgement messages and call clear down signaling. A CES can operate more than one CES Time division multiplexing channel and every channel is demand assigned by the NCS. 8.4. SES Signaling Channel The Satellite earth station signaling channels associated with each forward time division multiplexing channel are received both by the network control stations and by the CES mainly for signaling from the Satellite earth station to the shore stations. Access by Satellite earth stations to a Satellite earth station signaling channel is done with the help of algorithm known as slotted ALOHA scheme and the addition of one mechanism over it is reservation of slots in the channel. If more than one Satellite earth station transmits the data at the same slot collision occurs as seen at the receiving CES. To reduce the time elapsed before Satellite earth station is aware that its transmission is unsuccessful. Signaling channel descriptor packet in the forward time division multiplexed indicates the current status of all slots associated with that signaling channel. Slot timing is based on the time division multiplexed frame of 8.64s. Fourteen slots are allocated for the time of one data frame and 28 slots for future generation satellites. Any kind of Information which is to be transmitted in any slot is scrambled and half rate convolution encoded. The transmission rate is 600 symbols per second for current generation satellites and 1200 symbols per second for future generation satellites. Burst 120 information bits could be adjusted in one slot. The bursts do not contain acquisition preamble which are transmitted in the slots. This thing helps to maximize the signaling channel capacity. 8.5. SES MESSAGE CHANNEL Satellite earth station message channels are used by Satellite earth stations to transmit their messages to the chosen control earth satiations. Satellite earth station signaling channel is used in the call setup phase, but the message itself is sent on Satellite earth station message channel assigned by the control earth station. Access to the channel by Satellite earth stations is on a time division multiple accesses. The destination control earth satiations instructs each Satellite earth station to wait for the proper time to transmit, the time at which it can start transmitting. Once assigned a start time Satellite earth station will transmit its entire message without interruption. Any Information which is to be sent is formatted into fixed packets with fixed size and placed into the frames. Different frame sizes are available although the size is fixed for a particular transmission. Frame can contain between one and five packets depending on its size. Each packet contains 127 b ytes of information. Frames are scrambled, at half rate convolution and interleaved. A preamble is added before transmission. Transmission rate is only 600 symbols for current generation satellites and it will reach to 200 symbols per second for future satellites. 8.6. Inter-station Links Control earth stations offering C services have bidirectional links with the network control signal of the same region. This type of link is used to transfer announcements and Enhanced Group Calls messages from a Control earth station to the network control signal for the subsequent transmission on the network control signal common channel. In addition, signaling is shared on this link to make sure synchronization of access to Satellite earth stations and for the allocation of Control earth stations time division multiplexed channels by the network control signal. The transmission rate is 1200 bits in one second with no error correction techniques are employed. 8.7. Inter-Region Link Each network control signal is linked to the other Network control signals by inter region link channel. Mainly this channel is used to update other regions of any registration process by Satellite earth stations in a particular region. Automatic dial-up voice band data channels is used by this link over the public switched telephone network. These links operate at 600 bits per second, using CCITT V22 full duplex modems. 9. CHANNEL CHARACTERISTICS 9.1. Link Budget Considerations The performance of customary analogue data links is specifically defined for a specific threshold value at the receiver demodulator and the link accessibility is defined as the %age of time that certain threshold value is likely to be achieved. Standard C uses ARQ technique to re-transmit error packets. Due to this reason changes in demodulator do not affect the standard quality of the received message but it affects only the counts of re-transmissions needed to make sure that the complete message can be decoded without error at the receiver. In order to reduce the loading on the satellite the sum of energy per message transfer transaction must be reduce to limited extent. The forward link is more critical in terms of satellite resources and power reduction for this will degrade the demodulator receiver and the error rate for the packets will increase. Therefore more repeat packets will be required and result will be satellite capacity utilization. And all this is because of extra total message energy required in transmitting the repeat packets. Over this the drawback one additionally drawback is the time needed to complete the message transfer would increase. For best satellite capacity operation the satellite power should adjusted such a level that the sum of all message energy could be minimized. For this practice one forward TDM may serve many satellite earth stations and the power could be set to ensure a distribution of rate of error in packet across the satellite earth station population. 9.2. Signal Processing Features For the forward error correction half rate convolution is used on all the channels. A relatively short length allows the usage of maximum likelihood decoding techniques which can provide power in the region of 5 dB gain in an un-faded link. Similarly as a baseline for perfect performance limits, a decoder (Viterbi) has been assumed operating on three bit soft decision samples. A data bit going through the encoder is capable to influence group of 14 consecutive symbols and thats why the fading bandwidth is much less as compared with the actual data rate. All fourteen symbols could be affected by a fade. Now for time division multiplexing and message channels encoded symbols are assembled in a block before its transmission. After that they are transmitted in a different order. This interleaving has great effect on signal transmission. This interleaving process spreads transmission of the fourteen symbols connected with a given data bit over entire length of time which is large as compared to the fade duration. De-interleaving of the encoded symbols at the receiver side is used to convert successfully the long duration fades into the arbitrary noise which the decoder is capable to tackle because only 14 symbols could be corrupted due to a usual fade. The redundancy established in to the transmitted symbol stream allows restoration of the original data. For the Satellite earth station signaling channel with burst mode, interleaving is not employed as the bursts are very short duration for any kind of major effect. Data scrambling is also used on all the channels and it is necessary to ensure enough symbol transitions for clock recovery on demodulator side. Each packet contains the 16-bit checksum field which is transmitted on any of the INMARSAT C channels. Then it follows de-interleaving, decoding and descrambling operations, on the receiver checksum is calculated for each packet in order to find if the packet has been received is free of error or not. Channel time is given in figure below Figure 3. Channel time 10. DEVELOPMENT TOOLS 10.1. Simulation In the simulation environment characteristics of the Standard-C system in respect of the channel environment and the protocols are used because the analysis by conventional techniques is not suitable for examining the performance of system and many types of simulators have been used. Some of the simulations techniques and software programs are briefly described below: 1. Software program based on the TOPSIM language has been prepared to analyze the packet error rate in the forward and return links and the effect that various channel exhibit on performance. 2. LOTUS 123 has been used for analyzing the effect of certain traffic loading on a given network configuration. Using this software the results have been very useful in showing the capacity of the network and delays expected under different scenarios. 3. Simulator of testing demodulators is also there. This simulator allows the testing of demodulator functions in the multi-path fading conditions. Such kind of test equipment is not present in the market. 4. HOCUS simul

Discipline and Students with Disabilities Essay -- Special Education

Public Law 94-142: The Education for All Handicapped Children Act of 1975, now called Individuals with Disabilities Education Act (IDEA), requires states to provide free, appropriate public education (FAPE) for every child regardless of disability. This federal law was the first to clearly define the rights of disabled children to receive special education services if their disability affects their educational performance. A parent of a special education student also has basic rights under IDEA including the right to have their child evaluated by the school district and to be included when the school district meets about the child or makes decisions about his or her education. If a child is identified as in need of special education services, the school district must devise a written individual education program (IEP) for the child, which includes related services. An IEP is a statement of a student’s special education and related services including speech services, psycholog ical services, physical and occupational therapy, counseling and assistive technology and transportation. In addition, this legally binding, individualized plan outlines reasonable educational goals for the student and is reviewed and updated yearly. The Individualized Education Program is developed by a team that includes the parents of the student, a general education teacher, a special education teacher, a school representative (principal), a person knowledgeable about evaluation (school psychologist), and others at request of IEP participants. The primary job of the IEP team is to plan a program of special education and related services that is reasonably calculated to provide a meaningful education benefit. The IEP Process includes a review of assessme... ...behavior was not a manifestation of the student's disability and the student is suspended beyond 10 days, educational services, including access to the general curriculum, must continue. Special education services may not to be interrupted during the manifestation process or long-term suspension. Works Cited Fischer, L., Schimmel, D., & Stellman, L. (2007).

A Tragedy Revealed: A Heroines Last Days

A Tragedy Revealed: A Heroines Last Days Today you are going to read an amazing story wrote by a man named Ernst Schnable, this story is about a young girl named Anne Frank. Anne Frank lives in Amsterdam. Anne and her family must go into hiding at the Secret Annex to hide from the Nazi’s. After two years of hiding they are found and taken away to a concentration camps. Today I will be telling you about Anne and some characteristics about her. Anne is very confident, energetic, and also very caring.Anne is confidant in many ways, she is confident because when things go wrong or people start to think negative Anne stays strong, and positive. Anne always sees things on the bright side why think negative when you can think about things in a positive way. Anne also does not give up when she is taken away from her family and friends and sent away to a concentration camp. While Anne is away at the concentration camp she is kind of happy to be there because she gets to feel the cool b reeze, smell the air, and see the sky.When other people saw how confident Anne was they thought why not be confident to and have hope in being free soon. Anne is energetic because she is always talking, smiling, and playing around trying to have some fun. Before Anne went to the Secret Annex, she went to school and did normal things just as we do now. One day while she was at school she was talking so much that her teacher called her Ms. Quack Quack. Even though Anne has went into hiding she still trys to have some fun, though she must be quiet all day she still manages to have fun in any way possible.Anne is also caring because she loves to be around people. She always loves to help anyone when they are in need of something. Though at times Anne may argue with her mother about helping her do house work Anne really has a soft heart. The one thing that I found very touching was that Anne stayed by her sister Margot’s side the whole time she was ill until she passed away. Now y ou know some characteristics about Anne Frank, but their are many more than just the three I have listed. I recommend this story to any age or skill level reader.This story teaches you a lesson on what we should think about people and things, and that we should take a second look at the different things in life. I hope this story will delight you as how she did me, and to imagine what she felt when she was in this situation, and try to relate with one of your own experiences. I hope you enjoy this lovely story about a girl named Anne Frank. Also think of other characteristic than just confident, energetic, and caring, and see the bright side of things as did Anne. Do pass on this story as a reminder that threw good or bad everything happens for a reason.

The genre that I have chosen is comedy Essays

The genre that I have chosen is comedy Essays The genre that I have chosen is comedy Essay The genre that I have chosen is comedy Essay Essay Topic: The Chosen The genre that I have chosen is comedy is comedy. The reasons for why I have chosen this genre are that I know a lot about this genre as I usually watch comedy films in my spare time, so I also enjoy it to. The aspects that make a comedy a comedy are the 1 liners, the toilet humour, people hurting themselves humour, sexual innuendos and the fact that most comedy are funny in their own little way. Comedies are light-hearted dramas that are used to provoke laughter and amusement for the audience watching it. The comedy genre achieves this by exaggerating the situation, the language, actions and characters. There are many different forms of comedy including: Slapstick This is comedy with broad, aggressive, physical action, including harmless or painless cruelty and violence and sight gags, e.g., a custard pie in the face, collapsing houses, a fall in the ocean, a loss of trousers or skirts, runaway crashing cars, people chases, etc. The most recent of this type of film is Ace Ventura: Pet Detective (1993) Verbal Comedy This was classically typified by the cruel verbal wit of W. C. Fields, the sexual innuendo of Mae West or the verbal absurdity of dialogues in the Marx Brothers films, or later by the self-effacing, thoughtful humour of Woody Allen. Screwball Screwball comedies are light-hearted and romantic stories, commonly focusing on a battle of the sexes. They usually include visual gags, wacky characters, a fast-paced plot, and rapid-fire wisecracking dialogue reflecting sexual tensions and conflicts in the blossoming of a relationship (or the patching up of a marriage) for an attractive couple with on-going differences. Parody or Spoofs These types comedy are usually humorous take-offs of more serious films. These types completely over exaggerate the plot, the action and especially the characters in order to have its mocking type of effect. The most recent of these types of films is Scary Movie 1 2, both a take off of successful horror films. Cinematic comedy can be considered as the oldest film genre, it was ideal for the early silent films as it was dependent on visual action. The earliest comedy made was produced by the Lumiere Brothers in 1895 and was titled Watering the Gardener There have been many comedies released over the last century the most recent releases have been: American pie 1 2 Road Trip Scary Movie 1 2 Other films that fit in with this genre include: Shriek if you know what I did last Friday 13th Ace Ventura Dude, wheres my car? Dogma Plot The plot of comedies usually depends on the type of comedy the film, whether it being spoof comedy or screwball comedy they all differ. Although there are a few similarities, all comedies use sight gags, 1 liners etc, in order to stay with that genre. Examples, Road Trip use many visual gags. Characters In most comedies the characters can be easily stereotyped. There is always a Cheerleader or Captain of a football team, there is always a Dumb Blonde who never gets the jokes and there is always a Sexually Frustrated Geek. Occasionally, the comedy genres add a Goth or Rocker or someone of an alternative scene into a film. Examples Scary Movie and Cant Hardly Wait. Narrative The way in which the story is told revolves around the 1 liners, the sexual innuendos etc Stars The stars that are most likely to be associated with this genre are: Charlie Chaplin, Harry Lloyd and Buster Keaton and a more recent actor Seann William Scott etc. The 2 film covers above are American Pie 2 and Scary Movie. American Pie 2 and Scary Movie have many differences, the most obvious of which is that American Pie 2 has some relation to Screwball comedies and Scary Movie has relation to Parody or Spoof comedies. Whilst American Pie 2 exaggerates aspects of the film, Scary Movie overly exaggerates the film mocking most slasher movies, i.e. Scream, I Know What You Did Last Summer etc. The Films both rely on visual gags, but Scary Movie uses much more of them to add to its mocking tone. Soundtracks, American Pie 2 uses a romantic sort of soundtrack whilst Scary Movie uses a more haunting soundtrack in order to stay as a parody of slasher films. In similarities, both American Pie 2 and Scary Movie have the stereotypical characters of the comedy drama; there is the Cheerleader Buffy in Scary Movie and Captain of the team Oz in American Pie, there are the sexually frustrated geeks, Jim and Bobby.

HIGHBALL What is highball? An exaggeration of the truth to benefit the person that is highballing. To stretch the truth. To extend the truth to fit one’s idea of what should have been the truth in their mind. An outright LIE! You’re going to class and you see a fellow classmate and you both have Biology together.

An example of this would be when a salesperson is asked what their yearly average is, and they respond that they average 10 units a month. In actuality this salesperson has only sold 10 units one of the months out of the whole year. The salesperson has just highballed his average so that it would sound as if he was averaging about 10 units each month. The same can go for customers. I personally have been a sales associate.

International trade theory Essay Example | Topics and Well Written Essays - 1500 words

International trade theory - Essay Example Economists beginning from the age of Adam Smith nevertheless, have vehemently refuted this theory and established the concept of comparative advantage which could arise only when the scope of international trade is open. Comparative advantage theory which is widely followed today states that factors of production are not available uniformly around the world. It is wise for a nation not to invest in producing all its needs; rather it could specialise in the production of the good which could be produced most efficiently and at the cheapest rates (Peng, 2008, p. 127). This is the innate strategy being followed by most successful nations in the world today. Hence, it could be claimed that mercantilism is a bankrupt theory that has no place in the modern world. Answer to Question 2 Free trade is an economic phenomenon which supports an unbarred flow of goods and services across international boundaries. Since there is no government intervention in this case, the actual demand and supply positions of the commodity in question is reflected through its market price. Since there are no mark ups to prices, such a policy is advantageous for the producers as well as consumers of the concerned commodity. However, government intervention could be regarded as necessary in case of certain exhaustible resources whose supply needs to be rationed to guarantee future consumption as well. Such a restriction cannot be imposed in situations where free trade exists. A good example is that of oil prices which had been at pretty low rates prior to 1971, when these values were guided by market mechanism. However, concerns about the precious resources being replenished compelled the World Trade Organisation to sanction its restrictive use. Answer to Question 3 There has been an increasing tendency among developed nations to assume a protectionist position in many aspects of international trade. Many of them who had previously sought the services of less developed or emerging nations to c ater to the needs of their residents, have turned dead against such a strategy, posing a view that such a mindset could hamper employment opportunities in the recipient nation. They have termed it as â€Å"unfair† import competition due to the potential loss of jobs that such practice is leading to. Such a standpoint however has differentiated impacts upon various sections of the recipient nation. (a) It might be of high interest for the union houses who often adopt practices to apparently pacify the workers and show them the former’s alignment to them. (b) The people who are represented by the unions might be benefitted if the national government adopts such policies, since in the short run, they would be rewarded with higher employment opportunities. (c) The nation however, is likely to land up in a worse situation since they have to subsidise the companies which adhered to such practices. Even if they decide not to fund their needs, they would be in an inferior posi tion given that the companies no longer reap as wide a profit margin as before which reduces the national income statistics. Answer to Question 4 A free-trade regime had been supported by Ricardian economic theory after David Ricardo pointed out the scope of comparative advantage that partner

Proposal Assignment Example | Topics and Well Written Essays - 750 words

Proposal - Assignment Example These factors raised issues for the company with regard to Supply Chain Management (SCM) which further caused substantial decrease in stakeholders’ confidence. In this regard, the company will be provided with the opportunity of devising as well as implementing better policies and standards with the objective of improving business operations of its suppliers on a global context (Wal-Mart Stores, Inc., â€Å"Ethical Sourcing†). Solution In order to mitigate the above described SCM related issue, Walmart decided to undergo a massive restructuring process. In this context, the suppliers of the company were required to be ISO 9000 certified in order to provide goods to the company adhering to the specified quality standards which would not only assure an effective holistic approach in its SCM practices, but shall also prove beneficial in revitalizing stakeholders’ confidence. Moreover, with the ISO certification of suppliers, the company also expected to vitalize its ability to assure that the goods procured are in accordance with the specified quality standards. ... All these initiatives have apparently aided the company and its suppliers to perform their business operations applying increased ethical concerns in terms of quality and transparency (Plambeck and Denend, â€Å"The Greening of Walmart’s Supply Chain†). Why did you pick this topic? SCM is determined to be an important element for retailing and other related companies to perform their business operations in an effective manner. Moreover, with the growing demand for superior quality of goods and/or services are observed among consumers in worldwide market segments. The case of Walmart in relation to the SCM issues has been adopted for identifying the importance of ISO 9000 certification among companies which presents a relatively challenging and unique doctrine to be studied. What is it about this topic that interests you? The topic is based on the notion which signifies that SCM practices, within the organizational context are determined to be an important element which is essential to procure quality goods or services in an efficient manner. It is worth mentioning in this context that with the development of technology and globalization effects, the market competition has intensified. In this respect, consumers are also recognized to be demanding for superior goods at competitive prices. This particular understanding can be apparently observed with reference to the SCM practiced within Walmart wherein the suppliers are required to be ISO certified in order to assure that the goods procured are in accordance with the specified quality standards. Moreover, this topic also seemed to be emphasizing on the importance of principles and standards for conducting SCM operations in an ethical manner within the global periphery. What
