Radio Frequency Identification (RFID) Technology: Gaining A Competitive Value Through Cloud Computing
Radio Frequency Identification (RFID) uses radio waves to track the movement of goods through the Supply Chain system. The identity of an object is captured with a unique serial number that is transmitted wirelessly to a computer system. Small businesses are facing RFID implementation barriers. The barriers range from the perspective of the consumer-goods manufacturers and retail organizations. We propose implementing RFID technology using cloud computing framework to alleviate or reduce the implementation cost which is the most prevalent barrier.
Analysis Of The Effectiveness Of Error Detection In Data Transmission Using Polynomial Code Method
Data transmitted from one location to the other has to be transferred reliably. Usually, error control coding algorithm provides the means to protect data from errors. Unfortunately, in many cases the physical link can not guarantee that all bits will be transferred without errors. It is then the responsibility of the error control algorithm to detect those errors and in some cases correct them so that upper layers will receive error free data. The polynomial code, also known as Cyclic Redundancy Code (CRC) is a very powerful and easily implemented technique to obtain data reliability. As data transfer rates and the amount of data stored increase, the need for simple and robust error detection codes should increase as well. Thus, it is important to be sure that the CRCs in use are as effective as possible. Unfortunately, standardized CRC polynomials such as the CRC-32 polynomial used in the Ethernet network standard are known to be grossly suboptimal for important applications, (Koopman, 2002). This research investigates the effectiveness of error detection methods in data transmission used several years ago when we had to do with small amount of data transfer and data storages compared with the huge amount of data we deal with nowadays. A demonstration of erroneous bits in data frames that may not be detected by the CRC method will be shown. A corrective method to detect errors when dealing with humongous data transmission will also be given

Students Perceptions Of Cheating And Plagiarism In Higher Institutions
There is a growing body of evidence that cheating and plagiarism are prominent problems in many universities. In informal conversations, it seems that different students perceive plagiarism differently. In this paper, we conducted a survey at Howard University to examine or to follow up with this growing trend. Specifically, team leaders in school of business were surveyed early in the Spring Semester of 2010 at a meeting and Freshmen were given the same survey at the end of the semester after their final examination. From the data generated in this survey, we determined the prevalence of cheating and the reasons why students cheat. This report is of great importance because it exposes the extent of academic dishonesty and, if successfully implemented, it could provide resources that would aid universities in solving the cheating problem
Effect of tripanosomicide benznidazole (Rochagan®) on the biodistribution of sodium pertechnetate (Na99mTcO4) in Wistar rats
Benznidazole, a drug with specific anti-Trypanosoma cruzi activity, is used in the treatment of Chagas' disease. The radiopharmaceutical sodium pertechnetate (Na99mTcO4) is used to obtain diagnostic images of the stomach, thyroid, parathyroids, salivary glands, brain and in the study of esophageal reflux and blood flow. This study aimed at evaluating in vivo the influence of benznidazole treatment on the sodium pertechnetate biodistribution in Wistar rats. The percentage of radioactivity per gram (%ATI/g) of various organs (brain, heart, esophagus, stomach, small intestine, large intestine, spleen, liver, muscle and blood) was determined. Comparing the treated rats with the controls, we observed that sodium pertechnetate biodistribution did not change when administered to rats treated for thirty days with benznidazole.<br>O benzonidazol é um quimioterápico com atividade específica anti-T. cruzi utilizado por milhares de pessoas para tratamento da doença de Chagas. O radiofármaco pertecnetato de sódio (Na99mTcO4) é utilizado na obtenção de imagens diagnósticas do estômago, tireóide, paratireóides, glândulas salivares, plexo coróide, cérebro e de estudos de refluxo esofágico e de fluxo sanguíneo. Esse trabalho objetivou avaliar in vivo a influência do tratamento crônico com o benzonidazol na biodistribuição do radiofármaco pertecnetato de sódio em ratos Wistar. O percentual de radioatividade por grama (%ATI/g) de vários órgãos (cérebro, coração, esôfago, estômago, intestino delgado, intestino grosso, baço, fígado, músculo e sangue) foi determinado. Comparando-se o grupo controle e o tratado observou-se que o pertecnetato de sódio não possui sua biodistribuição alterada quando administrado em ratos tratados por trinta dias com a droga benzonidazol, mostrando não prejudicar a interpretação de diagnósticos por imagem
