Performance and Detection of M-ary Frequency Shift Keying in Triple Layer Wireless Sensor Network

This paper proposes an innovative triple layer Wireless Sensor Network (WSN) system, which monitors M-ary events like temperature, pressure, humidity, etc. with the help of geographically distributed sensors. The sensors convey signals to the fusion centre using M-ary Frequency Shift Keying (MFSK)modulation scheme over independent Rayleigh fading channels. At the fusion centre, detection takes place with the help of Selection Combining (SC) diversity scheme, which assures a simple and economical receiver circuitry. With the aid of various simulations, the performance and efficacy of the system has been analyzed by varying modulation levels, number of local sensors and probability of correct detection by the sensors. The study endeavors to prove that triple layer WSN system is an economical and dependable system capable of correct detection of M-ary events by integrating frequency diversity together with antenna diversity.Comment: 13 pages; International Journal of Computer Networks & Communications (IJCNC) Vol.4, No.4, July 201

A Classical Approach in Simple Nuclear Fusion Reaction 1H2 + 1H3 using Two-Dimension Granular Molecular Dynamics Model

Molecular dynamics in 2-D accompanied by granular model provides an opportunity to investigate binding between nuclei particles and its properties that arises during collision in a fusion reaction. A fully classical approach is used to observe the influence of initial angle of nucleus orientation to the product yielded by the reaction. As an example, a simplest fusion reaction between 1H2 and 1H3 is observed. Several products of the fusion reaction have been obtained, even the unreported ones, including temporary 2He4 nucleus.Comment: 3 pages, 2 figures, submitted to International Conference on Advances in Nuclear Science and Engineering (ICANSE) 201

The Effects of Cell Clustering on Cell Differentiation in Human Pancreatic Ductal Epithelial Cancer Cells

The thesis was funded by the College of Engineering by the Undergraduate Research Scholarship, when the project proposal was approved in April 2011.For diabetes mellitus type I, regular insulin therapy is not enough to completely control the disease. Ineffective control of blood glucose levels can lead to complications in other parts of the body, including kidney failure, neuropathy, cardiovascular disease, blindness, and acute hypoglycemic attacks. Although pancreatic transplants are one possible solution to reduce the effects of diabetes, it is not the best option. The proposed work of this research project is new and innovative with respect to hypothesis and methodology. It follows the goal to identify the role of cell clustering for differentiation of β cells so that the option of pancreatic islet transplantation can be substituted completely. Work by Boretti and Gooch in their paper “Induced Cell Clustering Enhances Islet β Cell Formation from Human Cultures Enriched for Pancreatic Ductal Epithelial Cells” was relevant to this project as it established the importance of clustering for differentiation of precursors cells into β cells. I used this work as a motivation to further research the amount of clustering required for the expression of insulin. My project speculates that the number of cells per cluster is essential for differentiated β cells to form. Further, there also must be a certain number of cells per cluster in order for proper insulin expression to take place. Upon experimentation, the results showed that cluster sizes of at least 4 cells per cluster were successful in expressing insulin as differentiated β cells. Whereas, small cluster sizes with only 1-2 cells per cluster were not able to express insulin. Further an area-to-perimeter analysis showed that ratios greater than 4.5 were common among insulin-expressing large cluster sizes. Although the results are quite preliminary, the investigation of the role that cluster size has on differentiation of β cells has a lot of potential for further research.The Ohio State University, College of Engineering, Undergraduate Research Scholarship (URS)No embarg
