Lnk between Literacy and Unemployment Research Paper

Lnk between Literacy and Unemployment - Research Paper Example A five step hypothesis test of data pertaining to the selection will be carried out and a description of the results will be carried out to answer the research question. Research question To what extent does the literacy level in a country impact on its unemployment rate? The sample is obtained from global demographics data about different countries and this information is provided. Since the crux of the report is to establish the link between literacy and unemployment rates in different nations, two countries namely Switzerland and Algeria have been chosen for this study to test the hypothesis. For instance, Switzerland has the lowest unemployment rate while Algeria has the highest rate of unemployment. Therefore, a critical analysis of this raw data will be carried out to test these statistics obtaining on the ground in view of the literacy rates of the respective countries. Formulation of the hypothesis As aptly stated by Struig & Stead (2001), a hypothesis depicts the relationshi p between two or more variables. In some instances, there is no relationship between the variables in a particular research. In this case, the null hypothesis is: There is no link between the literacy level and unemployment rate in a country. ... Hypothesis testing Step 1: The null hypothesis suggests that there is no link between literacy and unemployment rates in a given country and this is represented by H0: ?a= ?b. On the other hand, the alternative hypothesis is of the view that there is a correlation between literacy and unemployment rates in a given country and this is represented by H1: ?a ? ?b . Step 2: It is assumed that the probability of unemployment rate is higher when the literacy level of that particular country is lower. As going to be shown numerically below, the raw data presented is going to be calculated in order to establish if this assertion is true with regards to the stated question in the research problem above. Step 3: Test static value from the sample data provided from the two population proportions namely Switzerland and Algeria is going to be obtained through calculating the mean variance of the data. The table below shows the mean variance of the data between the two countries. Name of country L iteracy rate percentage Switzerland 99% Nigeria 57.1% Mean 78.05 From the statistics obtained from the table above, it can be seen that the mean static value is 78.05% and this is going to be used to evaluate the static. Step 4: The evaluation of the static is based on the mean obtained from the data provided about these two countries. The mean average static is 78.05 and it can be observed that from the raw data about the unemployment rates in the population proportions given, Switzerland has 1.9 % unemployment rate while Nigeria has 28 %. In terms of literacy rate, Nigeria has 57.1 % and is below the mean static of 78.05 % while Switzerland is above the mean static with 99 %. Step 5: from the results obtained above, it can be noted that the null

What more could happen if two large companies will merge? And these companies happen to cater services that are of importance to our fast moving lives- the telecommunications services? On November 24, 2011, an article entitled â€Å"AT&T Merger with T-Mobile Faces Setbacks† was published on nytimes.com by Edward Wyatt and Jenna Wortham. They talked about the problems that the two mobile companies, AT &T and T-Mobile, are facing with their planned merging. AT&T is one of the largest telecommunications services provider in the United States and even worldwide. Its services include wireless communications, local exchange services, long-distance services, data/broadband and Internet services, video services, managed networking, wholesale services and directory advertising and publishing. In March of 2011, it announced its plan to merge with T-Mobile which is owned by Deutsche Telekom. The former agreed to buy T-Mobile from Deutsche Telekom for $39 billion. But of course, the merger was subject to F.C.C. approval because the joining of the two companies would have required transfer of licenses to use public airwaves for cellular phone signals and wireless Intern et access (Wyatt & Wortham, 2011). Being a monopoly or even just a big player in an industry yields many advantages and if not properly monitored will affect the consuming individuals negatively. In the case of these telecommunications merger, different sectors from the society are paying close attentions. The Justice Department for example has said that the merger would severely restrict competition, Federal Communications Commission officials have added that AT&T’s confidential filings indicate the merger would eliminate jobs and consumer groups who closely monitored the actions of the authorities said that their combined actions indicated

Assessing Selective Human Genetic Engineering

Assessing Selective Human Genetic Engineering Nora Sheskey Selective Genetic Engineering For millions of years, genetic selection has been the result of natural selection. Who someone is, natural abilities, physical characteristics, and a wide range of other personal attributes were the result of genetic recombination and accidental mutation. Furthermore, children are often born with hereditary conditions which are set by factors we have no control over. However, the advent of modern medicine has brought us to the brink of a time when we can choose to redirect nature and repair maladies in children, where we can artificially modify the very codes which guide their looks, which diseases they are resistant to, and even their personalities. Considering the facts concerning genetic engineering, the benefits which can be achieved far outweigh the potential risks with regard to both the reduction in human suffering and the likely increase in lifespan. The opponents of human genetic engineering often refer to a number of dangers involved in artificially manipulating genetic codes which result in such medical issues as Down’s syndrome, Hemophilia, and even anxiety and stress. With the completion of the Genome project, we can now more accurately map the human DNA than ever before, identifying the locations of defects that cause many of the maladies that have plagued mankind for millennia. Opponents of genetic manipulation are quick to point out that a slight error in the manipulation process can result in changing other sequences that could result in unforeseen and undesired effects. For instance, researcher Russell Powell has speculated that human genetic engineering might result in a lower genetic diversity which could lead to future generations that are more prone to having some types of diseases and which could, potentially, lead to the human race becoming extinct. Part of his research showed how genetic manipulation of cr ops in order to increase the availability of desirable crops increased the likelihood of catastrophic crop failure due to those crops becoming less genetically diverse over time and having reduced resistance to environmental factors which a wider genetic base would have prevented. He studied how such factors led to the nineteenth century Irish Potato Famine and how the organism Phytophthora was able to decimate much of the potato crop in Ireland due to this reduction in genetic diversity because of the farming methods in use in that region during that period of history. His research demonstrates that by reducing human genetic diversity through such techniques as genetic manipulation those human beings could set themselves up for a similar fate (Powell, R. 2012, pp. 204-5). Also, the work of Charles Gillespie, et. al., into how genetics affect the human stress response found that stress related genetic mutations in developing human fetuses increased the individual’s susceptibi lity to disorders such as depression and post-traumatic stress disorder later in life. They found that natural genetic manipulation due to a change in the hypothalamic-pituitary-adrenal balance lead to an increase in susceptibility to stress related disorders in the associated human beings (Gillespie, C. F., 2009, p. 990). Opponents of genetic manipulation point out that accidentally manipulating the incorrect gene sequences could result in the same type of condition. Opponents use facts such as these in their outspoken aversion to the practice. Proponents of genetic engineering rebut the opponents by pointing out that the benefits of curing medical issues like Down’s syndrome and Hemophilia far outweigh the possible risks. They counter the opposition with a number of research studies. As part of his research, Powell determined that human genetic diversity is due to a combination of both mutation and recombination (Powell, R. 2012, pp. 215). He found that a number of different phenotypes can result from a single genotype which led him to conclude that accidental activation of inactive or incorrect sequences is unlikely to produce feared dramatic issues often spoken of by human genetic manipulation opponents. Additionally, he found that focusing on only DNA adaptive variation involved in human genetic manipulation would not result in an extensive homogenization of the human DNA feared by opponents and that other environmental factors play a significant part in human genetic diversity (Powell, R. 2012, pp. 207-8). In ad dition, Gordon and Hen found that properly utilized genetic manipulation can provide many useful results with an acceptable margin of safety. They studied twins to determine how anxiety response is genetically associated and how DNA sequencing and correction could help to treat the condition. They document that comparisons of fraternal and identical twins showed that 30% to 50% of risk of developing anxiety disorders comes from genetic factors with the remainder being attributed to environmental causes. They also used studies of rats and mice to show that anxiety is a genetic condition and could be treatable using genetic manipulation techniques (Gordon, J. A., Hen, R., 2004, pp. 195-6) Opponents of human genetic engineering further turn to natural selection in their opposition to the practice. They point out that altering how nature and evolution have brought things about can have unintended consequences. As evidence of this, they look at the research of Richard A. Miller. Miller found that manipulating certain genes associated with aging in what he refers to as UM-HET3 mice, a group of 1800 specimens, sometimes actually shortened rather than lengthened the average lifespan as well as hastened the onset of reduced cognitive abilities in the mice which received such treatments. He additionally found that when other specific genetic sequences were modified, the result was an increase in the occurrence of and age at which cancer occurred in some cases. His research also showed that not only could the aging process be sped up due to genetic manipulation but could also increase the severity of old age issues. Additionally, some of the traits which occurred later in life could not be detected in the early stages of life. Miller found that these traits affected a number of aspects such as bones, eyes, hormones, weight, and what kills the individual. Miller eventually admits that there are things which nature has brought about which we cannot yet reproduce in the laboratory and opponents of genetic manipulation question if such research is worth the risks (Miller, R.A., 2005, pp.S284-5) Opponents of genetic engineering also refer to the work of Brown who examined that practice from a viewpoint of Rawlsian Justice. He points out that such a practice still needs to be considered from both a moral and a legal framework. He states that â€Å"The important point is that until now, theories of justice have regarded one’s genetic endowment as a fixed fact of nature rather than as a matter of justice.† He indicates that manipulating individuals alters their right to have an equal claim to the same equalities and fair equalities as others. The o pponents of genetic manipulation take the viewpoint that altering who has what rights is inherently wrong and does not actually improve the overall human condition (Brown, 2007, pp. 83-84) Proponents of human genetic engineering, on the other hand, believe that we, as human beings, are finally able to improve on that which nature has brought about after millions of years of evolution. They point out that nature has evolved such things as cancer and shortened lifespans in their support for genetic manipulation. They also look to the work of Miller and say that in spite of some cases where the lifespan was indeed shortened that in many other cases the lifespan is nonetheless longer. Their viewpoint is that by performing an analysis of the differences between DNA of the long and short lived mice that researchers will be able to eventually track down which genes do lead to longer lives. Miller himself states that there are genes which influence the age at which the various mice die, such as a pair of genes on chromosomes 2 and 16, which lead to mice living up to 173 days longer than mice that do not have this particular DNA sequence. Likewise, Miller states that there are also DNA sequences which also affect the age at which certain cancers occur in some of the mice in his study. He goes on to say that his research indicates that there may be â€Å"a specific aging process that we can learn enough about to modify or prevent.† Miller ends his paper by stating â€Å"Will genetic manipulation or pharmacologic agents suggested by genetic research offer a realistic possibility of life expectancy at birth of 110 or 120 or more years? Twenty years ago, this was a science fiction question, but no more, and it is interesting to speculate based on current evidence. I believe the answer is yes.† (Miller, R.A., 2005, pp. S284-5) After having examined information from both those opposed to and those in favor of human genetic manipulation, we can most certainly say that both sides have some strong arguments in favor of their viewpoints. Those opposed to the practice would appear to come from a traditional perspective, fearing the changes necessary in order to make the necessary strides that will be required in order to bring about substantial gains to be realized from genetic engineering. Taking history as a guiding principle, they see how the best intentions often result in severe negative results before gains can be realized. They see in the work of researchers like Gordon and Hen, Miller, Powell, and Gillespie the backing to state that the possible gains are either not possible or are not warranted by the necessary costs that will be imposed. The proponents of the practice of human genetic engineering believe that any time we can relieve human suffering and eradicate disease that the benefits outweigh the c osts. They are motivated by the belief that any change which improves the human condition is worth the risks and that any time we can repair genetic defects that we are doing humanity a much needed service, even when that service means that we alter the very codes which determine who a person is. They acknowledge the risks posed but believe that a future without birth defects, without Down’s syndrome, and without other such genetically linked issues is worth risking for. They find in the works of Miller, Powell, Gillespie, and Gordon and Hen an exciting roadmap to a world where human suffering based on the genetic structure has been eliminated. Personally, I am inclined to agree with those who say that we must go boldly forward and take the necessary risks in order to improve the human condition in every way possible. History has shown us that such journeys are not without risk but almost always inevitably prove beneficial to future generations. If we are to let fear guide us, we would have never developed such medical miracles as penicillin, the polio vaccine, or the heart transplant. No valiant effort in human history has ever come without costs and moving forward with research in genetic manipulation is sure to impose upon mankind the same kinds of costs imposed by the research of Pasteur, Salk, and Fleming. Mankind has never been the type to simply not advance and the next frontier would appear to be human genetic engineering. In conclusion, we have finally come to an age in human history where we can choose to modify the very codes that define who we are and how we develop. We can decide whether to allow such disorders as Down’s syndrome, Hemophilia, and severe anxiety to continue to plague the human race. The advent of modern medicine has brought us to the brink of a time when we can choose to redirect nature and repair maladies in children, modifying the very codes which guide their looks, which diseases they are resistant to, and even their personalities. The opponents of genetic manipulation believe that the risks involved far outweigh the potential gains. The proponents believe that we cannot let fear hold us back from improving the human condition in any way we can. So, considering the facts concerning genetic engineering, we can at this point say that based on the research and evidence at hand, the benefits which can be achieved far outweigh the potential risks with regard to both the reduct ion in human suffering and the likely increase in lifespan.

Analysis Of The Ending Of death Of A Salesman :: essays research papers

Analysis of the Ending of "Death of a Salesman" The play "Death of a Salesman" shows the final demise of Willy Loman, a sixty- year-old salesman in the America of the 1940's, who has deluded himself all his life about being a big success in the business world. It also portrays his wife Linda, who "plays along" nicely with his lies and tells him what he wants to hear, out of compassion. The book describes the last day of his life, but there are frequent "flashbacks" in which Willy relives key events of the past, often confusing them with what is happening in the present. His two sons, Biff and Happy, who are in their 30's, have become failures like himself. Both of them have gone from idolizing their father in their youth to despising him in the present. On the last few pages of the play, Willy finally decides to take his own life ([1] and [2]). Not only out of desperation because he just lost his job, with which he was hardly earning enough to pay ordinary expenses at the end. He does it primarily because he thinks that the life insurance payout [3] will allow Biff to come to something [4], so that at least one of the Lomans will fulfill his unrealistic dream of great wealth and success. But even here in one of his last moments, while having a conversation with a ghost from the past, he continues to lie to himself by saying that his funeral will be a big event [2], and that there will be guests from all over his former working territory in attendance. Yet as was to be expected, this is not what happens, none of the people he sold to come. Although perhaps this wrong foretelling could be attributed to senility, rather than his typical self-deception [5]. Maybe he has forgotten that the "old buyers" have already died of old age. His imagined dialogue partner tells him that Biff will consider the impending act one of cowardice. This obviously indicates that he himself also thinks that it's very probable that Biff will hate him even more for doing it, as the presence of "Ben", a man whom he greatly admires for being a successful businessman, is a product of his own mind. But he ignores this knowledge which he carries in himself, and goes on with his plan. After this scene, Biff, who has decided to totally sever the ties with his parents, has an "abprupt conversation" (p.99) with Willy. Linda and Biff are in attendance. He doesn't want to leave with another fight, he wants to make peace

Narcissus and Echo: Focus on Oedipus in the Story Essay

Echo and Narcissus is one of the tales penned by Roman poet Ovid in Metamorphoses. These 15 books of Metamorphoses, tells the creation and history of the ancient world. It still holds the honor of being the most popular work on Greek and Roman mythology. Echo and Narcissus, the tale of a nymph and hunter, has long been considered by most scholars as one of the most tragic tales of all times. The metamorphosis of Oedipus is a tragedy to bring a particular ethical conclusion to fruition. The character, Oedipus, in the beginning had to disclose his tragic flaw. In the beginning he was a brilliant conqueror and but became a blind man in the end. However, the moral the tale presents is not merely the consequences of trying to avoid one’s fate. â€Å"But Tiresias shook his head his gray head in warning: ‘Blindness†¦Might be blessing in your case, to keep you ever looking on the rites of Bacchus, The day is near, I know, when the new god shall come, the son of Semele, whose due is I worship from you; if you scorn his temple, you will be torn into a thousands pieces, your blood pollute the wood, and it defilement spatter your mother and your mother’s sisters†. (Ovid, 73) His fate was put in place before he started his journeys, while Tiresias was his inverse at the time of blindness. Although Oedipus has no knowledge or awareness that he has killed his father and going to marry his own mother. Sooner he becomes conscious that the prophecies have come to pass because of and despite him. Oedipus conquered the Sphinx and then grew weaker and weaker until he finally discovered he was the guilty of sexual immorality. â€Å"Oedipus experienced a metamorphosis in which he was originally the greatest man, but by placing himself and his ‘wisdom’ above the gods or God’s, he fell†.

Sms Based E Notice Board

Abstract The goal of this project is to design an embedded device which can control up to 8 devices by sending a specific SMS message from a cell-phone. This controller is extremely handy at places where we have to control the ON and OFF switching of the devices but no wired connection to that place is available. To implement this, a GSM modem is connected to a programmed microcontroller which would receive the SMS from a reference cell phone. The control signal part of the received SMS is extracted and is changed to microcontroller-preferred format.In regular intervals, the modem would also send the local temperature We have selected GSM because the ubiquity of its standard makes international roaming very common between mobile phone operators, enabling subscribers to use their phones in many parts of the world. A PC which is connected to the micro-controller using a serial communication through RS232 can be used for monitoring and transmission of the control signals to the modem. T he monitoring is also done by interfacing a LCD to the microcontroller. AT commands were used for controlling the functionality of modem. Main hardware requirements:Renesas SKP16C62P Starter Kit Plus This contains the micro-controller. (used for controlling the different external devices connected as per the SMS received ) GSM modem (GM28 from Sony-Ericsson) This GSM/GPRS terminal equipment is a powerful, compact and self contained unit with standard connector interfaces and has an integral SIM card reader. It is used for receiving the SMS from the mobile device and then to transmit to the Renesas SKP. A MAX232 chip This converter chip is needed to convert a TTL logic from a Microcontroller (TxD and RxD pins ) to standard serial interfacing for PC (RS232) A DB9 connectorThis takes the signals coming form the MAX232 chip to the PC. The typical applications of this serial modem is for developing a wide range of equipment like Security and alarms devices Monitoring and control devices Vending machines Utilities devices Fleet Management devices Embedded Project- ECE 5101 Page 3 2. Project Description Renesas SKP16C62P Starter Kit Plus Device 1 Device 2 MAX 232 Device 8 DB9 Connector DB9 Connector GM28 (GSM Modem with SIM card working in 850 MHz /1900 Hz) Antenna Computer (For displaying the received SMS) Figure 1: Block diagram of the project setupInitially the SMS is received from the person authorized to use this setup (destination) by the GSM modem (GM28) & is transferred to the Renesas SKP16C62P SKP with the help of a MAX 232 chip. As per the AT commands given by the microcontroller to the modem, the control signal from the SMS is extracted and is used to control the devices connected to it. We have to convert the ‘septets' of the phone to ‘octets' because the micro-controller need bytes with 8 bits length ( The ‘septet' is 1 byte with 7 bits length and ‘octet' is 1 byte with 8 bits length). All this process is necessary to decode the m essage from SMS.A program (for extracting the control signal part from received SMS) is loaded into Renesas SKP16C62P SKP, and then the circuit is connected to the modem. The microcontroller now tries to read the SMS from the 1st memory location of the modem and it keeps trying again until the modem receives any (programmed for every one second). Before implementing the control signal part of the SMS, the modem extracts the number from the SMS and verifies if this number has the access to control the device or not. For controlling the devices, the message will be sent in hexa decimal format.The hex data is converted to the equivalent binary and the particular output is enabled. For example if the message is â€Å"AB† the equivalent binary is â€Å"10101011† this implies that the output 1, 3, 5, 7, 8 are enabled and the remaining ports are disabled. We have connected LEDs to the ports of microcontroller to show the output and their status indicates whether the ports are set to ‘ON’ or ‘OFF’. The microcontroller is also programmed to read the temperature from the thermistor every 15 minutes and to send a SMS to the destination number. Embedded Project- ECE 5101 Page 4 3. Device Description 3. 1. Renesas SKP16C62P Starter Kit PlusThe SKP16C62P StarterKit Plus (SKP) is a low-cost environment for evaluating M16C/62P group of microcontrollers (MCU) and Renesas Technology America, Inc. software development tools. The SKP board provides an evaluation and development environment for the M16C/62P group of MCU. It has pushbutton switches, LED’s and LCD for user interface. Standard connector ports are available to expand the range of applications through the use of expansion boards, etc. The kit comes with an integrated software development environment, HEW (IDE, C-compiler, assembler, and linker), KD30 Debugger, and FoUSB (Flash-overUSBâ„ ¢) Programmer.A real-time, source-level debug environment is implemented using the K D30 debugging software with the RTA-FoUSB-MON Flash Programmer/In-Circuit Debugger (ICD). The Flash-over-USBTM (FoUSB) Programmer software, with the ICD, allows in-system programming of the M16C/62P flash MCU. The ICD and firmware provide a convenient USB (Universal Serial Bus) interface between the SKP16C62P board and the host PC. This interface reduces resource requirements on the M16C/62P MCU, allows faster code downloads and, can also be used with many other Renesas Flash MCU’s, SKP’s, and user’s target board.Figure 2: SKP16C62P System Connectivity (From the hardware manual of SKP16c62P ) Embedded Project- ECE 5101 Page 5 3. 2 GSM modem: (GM28 from Sony-Ericsson) Figure 3. a Figure 3. b Figure 3. c Figures 3. a, 3. b and 3. c show the different views of the GSM modem GM28 (From the Hardware Manual of GM28 Modem) The Global System for Mobile Communications (GSM) is the most popular standard for mobile phones in the world.

GM28 in a Communication System Figure 10, Illustrates the main blocks of a wireless communication system using the TT4030 (SE-GM28). It also shows the communication principles of the system. The definitions in the figure are in accordance with the recommendations of GSM 07. 7. The MS (mobile station) represents the TT4030 (SE-GM28) modem plus SIM card. The modem excluding SIM card, is known as the ME (mobile equipment). The TE (terminal equipment) is a micro-controller and is a part of the application. Figure 10. a Main blocks in communication between the GM28 (modem) and the microcontroller (TE) (From the Hardware Manual of GM28 Modem) The end-to-end communication path to be established between the external telemetry/ telematics application and a remote terminal or host, via the GSM network is done through the serial communication.Serial data with flow control according to the RS232 signaling protocol operates between the modem and the external application. The modem performs a set of telecom services (TS) according to GSM standard phase 2+, ETSI and ITU-T. Control of the TT4030 (SE-GM28) is by the external application, via the RS232 serial interface, using a set of AT commands. The TT4030 (SEGM28) supports the full set of AT commands according to GSM 07. 05 and GSM 07. 07. It also supports an extended set of Ericsson proprietary AT commands to add extra functionality. Embedded Project- ECE 5101 Page 10AT commands are used to operate the modem a nd have a broad range of Functions including: Configuring general parameters of the modem (SE-GM28) Setting up and controlling communications to and from the GSM Network Configuring the modem to communicate across the RS232 serial interface Obtaining GSM network status information. Figure 10. b Interface between the GM28 (modem) and microcontroller (TE) (From the Hardware Manual of GM28 Modem) The modem also supports the Voice, Data, Fax services but since these are not required for the current application, they are not taken into consideration as of now. . AT commands The AT command set is the fundamental interface with the modem. An AT command is simply a string of characters preceded by the AT prefix that is sent to the modem. The commands typically instruct the modem to perform some action or set some characteristic within the modem. The modem has two states: command state and on-line state. In command state, the modem will accept and respond to AT commands. In the on-line state , the modem will transmit data, but ignore AT commands. Typically the modem is in the on-line state after dialing.AT commands has the following format: The command is prefixed with AT (Attention) The command is terminated by a carriage return (except the A/ command and escape sequence). The commands can be entered in upper case or lower case. The AT prefix can be in upper case or lower case, but both the A and the T must be the same case. Characters that precede the AT prefix are ignored. Multiple commands can be strung together on a single line and spaces may be included between commands but are not necessary. The command line interpretation begins upon receipt of the carriage return.These commands are used for request information about the current configuration or operational status of the mobile phone/modem and test availability and request the range of valid parameters, when applicable, for an AT command.

Installation and Functionality of modem To install this modem in the communication system to PC, the following procedure is adopted: †¢ †¢ †¢ Select the phone and modem options from the control panel. By browsing the disk for the modem drivers, the modem is selected and configured to a particular port through which it is connected to the PC. The terminal package like HyperTerminal is selected in the initial stage to check the functionality of the AT commands to control the GSM modem and later this hyper terminal is just used to monitor the serially received output.Hence finally a three way communication is established, the modem directly communicates with the micro controller to control the switching of devices externally and the hyper terminal package in PC is used just for monitoring the results (hence only receive and ground of connected to the PC). Embedded Project- ECE 5101 Page 12 †¢ †¢ The parameters for serial communication can be set in two ways; either by terminal equipment or by serial communicat ion with the micro controller. It should be noticed that the DTR pin should be enabled high in the initial tage to turn-on the modem, for this flow control of hardware is to be taken and the communication initially is 115200 bauds/second with 8-n-1 configuration (i. e. 8-Data bits, Parity none and 1-Stop bit). Later the baud rate can be changed to 9600 bps through the AT command: AT+IPR = . The settings for the hyper-terminal should have the default input translation and ASCII setup, the emulation can be either VT100 (preferable) or Auto-detect. To setup the serial port the following procedure has been followed: †¢ †¢ †¢ Select system from the control panel and thereby select the device manager in the hardware option.Now the exact serial COM port where the modem is configured is selected manually. Select port settings and then bits per second to get the exact baud rate. Now that the modem is configure it’s the task of setting up the volatile profile and enter t he AT commands required to select the SIM memory and then extract the text message. Hence, serial communication is established between GM28 and the microcontroller using a DB9 connector with a level shifter (MAX232). A level shifter is connected between the microcontroller (SKP) and the modem/computer and null modem connection is connected for the DB9 connector.The above discussed points are depicted in the Figure 9. Figure 9 Circuit for connecting the microcontroller to the modem/computer Embedded Project- ECE 5101 Page 13 9. Short Message Service (SMS) The GSM GM28 Modem supports the following SMS services. Sending, MO (mobile-originated) with both PDU (protocol data unit) and text mode supported. Receiving, MT (mobile-terminated) with both PDU and text mode supported. CBM (cell broadcast message), a service in which a message is sent to all subscribers located in one or more specific cells in the GSM network. This feature is network dependent.SMS STATUS REPORT according to GSM 03 . 40. SMS COMMAND according to GSM 03. 40. It should be noted that the maximum length of an SMS message is 160 characters when using 7- bit encoding. For 8-bit data, the maximum length is 140 characters. The Modem supports up to 6 concatenated messages to extend this function. Before we start working on the application design we should ensure the network subscription status Before the application is implemented, we must ensure that the chosen network provides the necessary telecommunication services. Else, the service provider should be contacted to obtain the necessary information.Since SMS features are used in this application, we have to ensure that these are included in the (voice) subscription. 10. PDU SMS format: There are two ways of sending and receiving SMS messages: by text mode and by PDU (protocol description unit) mode. We can switch from text mode to PDU mode and vice versa by selecting the AT+CMGF command. If AT+CMGF = 0 then PDU mode is selected and if the mode is 1 then text mode is selected. The text mode is just an encoding of the bit stream represented by the PDU mode. If we read the message on the phone, the phone will choose a proper encoding.An application capable of reading incoming SMS messages can thus use text mode or PDU mode. If text mode is used, the application is bound to the set of preset encoding options. In some cases, that's just not good enough. If PDU mode is used, any encoding can be implemented. The PDU string contains not only the message, but also a lot of metainformation about the sender, its SMS service center, the time stamp etc. But as of now for our application we require the phone number of the caller for authentication and the length of the message and the text message which contains the binary message.Let us take a example for the text message of â€Å"abcdef†. This message contains apart from the basic text message a lot of redundant data (meta information about the sender). In PDU mode the SMS looks li ke: 07914140279542F7000B816187220731F700006010413283900A0661F1985C3603 In TEXT mode the SMS looks like: +CMGR: â€Å"REC READ†,†16782270137†³,,†06/01/14,23:56:1720†³,129,0,0,0,†+14047259247†³,145,6 abcdef Embedded Project- ECE 5101 Page 14 The octets of the PDU message contain lots of information, in the above example the PDU can be divided and different octets signify the following information: 07 Length of SMSC information. 1 Type of address of SMSC. 4140279542F7 Encoded Service center number. 00 First octet of SMS delivery message. 0B Address length of the sender message. 81 Type of address of the sender number. 6187220731F7 Sender number with a trailing F. (number is 16872270137). 00 TP-Protocol Identification Address. 00 TP-Data coding Scheme. 601041328390 TP-SCTS Time stamp. 0A TP-User data length. 0661F1985C3603 Encoded Message â€Å"abcdef†. All the octets are hexa-decimal 8-bit octets, except the Service center number, the send er number and the timestamp; they are decimal semi-octets.The message part in the end of the PDU string consists of hexa-decimal 8-bit octets, but these octets represent 7-bit data. Basically the transformation of the septets to the octets is based on the GSM 03. 38 standard. This is helpful when we try to communicate with the PDU mode but if we use the CMGF command then text mode is activated to get the converted text message. So to get the message in the Text message we need to send the following commands AT+CMGF=1 to activate the text mode AT+CMGS=1 to check whether the modem supports the SMS message or not.AT+CMGR=I to read the message at the location I in the SIM card. 11.

Good exercise and diet  habits are key aspects not only in appearance but in living long, healthy lives. One may look fabulous, both fit and healthy while being just as unhealthy as an obese person. The exact opposite is true, also. A person may be a little overweight but have a healthy heart and diet. The only way to find out if one is eating healthy and getting the proper amounts and types of exercise is by looking at their diet and activity level. Diet Is a Way of Life It is important to first start with a good eating plan. Age, health issues, and level of physical activity are just a few factors that should be taken into consideration when writing a meal plan for a person. For example, a young, healthy, and active person can eat more freely than an older person with high cholesterol who does not get much physical activity. On average, a person should try to eat 6-11 servings of grains, 3-5 servings of fruits, 3-5 servings of vegetables, 2-3 servings of dairy, 2-3 servings of meat, and consume fats and sugars sparingly each day. One should shoot for this range until he/she can have an eating plan written for them. Diet is just as big of a part of your health as exercising, that’s why it is so crucial to eat well balanced healthy meals. This requires knowing what you are eating; you can obtain this by the dietary label present on the back of the food when you buy it in the grocery store. â€Å"Water is an essential for being healthy; you should drink 8-ounce glasses per day. Most people do not have a well-balanced diet like they should, but instead, have a diet high in fat and are not consuming enough fiber† (Gebhardt, 72). The best way to start towards a healthy diet is to start consuming more natural whole foods, such as fruit, vegetables, bread, cereals, potatoes, and pasta. You have six different food groups one of which would be a good idea to eliminate completely from your diet, the sweets. The other five groups which you need to focus on are the dairy group, meat group, vegetable group, fruit group, and the bread group. It is a good idea to try and eat a little from each of these groups with each meal. Also keep in mind that you need to be paying attention to the amount of protein, fiber, salt, vitamins, and minerals which you consume as well. These are a little bit harder to keep track of and have always caused more confusion. Customize Your Exercising Plan Diet is not the only thing that should be factored into a healthy lifestyle. Exercise is just as important as a nutritious diet. There are many benefits of physical activity besides the obvious advantage of having a better physical appearance. Exercise can reduce the symptoms of anxiety and depression and improve ones mood and feelings of well-being. Besides helping you look great it helps you feel great, too. There are different types of exercises which give different results. Strength training, such as lifting weights, produces dramatic differences in physical appearance and raises ones metabolic rate. It also improves athletic performance and builds stronger bones. Cardiovascular training builds a powerful heart and strong lungs. It helps prevent hypertension, obesity, heart disease, and Type Two diabetes. Exercise is not all about physical looks, it also has to do a lot with your actual health and well being. For example, many overweight people tend to be more susceptible to higher cholesterol and blood pressure. Well, by working out and adding an exercise routine into your normal everyday life, you can help to decrease risk factors drastically. It is said that over 60% of American grown-ups are on the heavier side, or overweight. Only about 15% actually engage in the slightest amount of exercise. â€Å"Obesity alone makes a person very vulnerable to heart disease, but also susceptible to an additional 65% chance of having at least one added risk for heart disease, diabetes and or stroke and a 50% possibility of having two or more of these as possible risk factors. Some other possible risks are high blood pressure, high blood sugar, cholesterol and blood fats that are not all curable with insulin and are considered the Metabolic Syndrome† (Lissner, 886-92). This becomes an even bigger risk when areas of fat accumulate around a person’s middle area and the organs in which the fat surrounds. Basically, people become obese by consuming more calories than should be consumed for a whole day and not using up that energy that has been consumed in calories by exerting it in a physical manner such as exercise. Some people have a fast metabolism which would be the people you see eating whatever they want and still look fit or have the average metabolism where you are what you eat, which makes it a lot harder to stay fit and lean. Exercise has also had a tremendous effect on the aging process of the body. Apparently, the increase in exercise has an enormous effect on nerve cell health and with how long those cells are alive. By maintaining these healthy cells it helps to promote the production of antioxidants which help to protect cells from damage, this is the leading cause of aging. No matter what your age is you can still benefit from exercise not only mentally but also help to prolong your ability to function later on in life. But most importantly â€Å"you will be reducing the chance of having a stroke and clotting which can result in deep vein thrombosis and death, which is more critical as we age† (Tremblay, 814-18). Keeping up a regular cardio routine is a great way to get in shape and also it helps benefit you in various prolonging ways. It is still a good idea to have weight lifting as a part of your routine too. There are six different muscle groups that you can work on with weights. You have arms, back, chest, shoulders, legs, and then abs. You want to try and keep them all worked out pretty evenly. Keeping it switched up and by not concentrating on lets just say bench press, you keep your body guessing and keep it from getting immune to the exercise. Instead of just doing bench press all the time you can switch it up to one week doing dumbbells, maybe cables the next, or maybe even just doing flat out push ups. Then you have the machine style workout which you can substitute in one week. Also, you can switch the focus point up, maybe you want to concentrate on your upper chest this week and lower or mid chest the following week. With this type of confusion, your muscles will grow much stron ger and you will notice much more of an improvement. Exercise and diet  are key factors in staying physically and mentally healthy. It is a known fact that if you look great and feel great you will live a longer and happier life. It is important to take ones age, health, and current physical activity level into consideration when writing an exercise and diet plan. There are many people out there, such as nutritionists, personal trainers, and even personal doctors, who can help develop a diet and exercise plan that is right for him/her. There are so many facilities out there to help keep you alive and healthy. Gebhardt, S.E., Matthews, R.H. (2006).
