Performance Analysis of Routing Algorithms[ ] [References]


As an emerging and advanced technology, Network-on-Chip (NoC) may become the alternative of the traditional bus-based System-on-Chip (SoC). In an interconnection network structure, interconnected routers are the core of the whole system and the network's performance mainly depends on their performance. There are many significant factors which determine the working mechanism of a router and its performance, such as topology, switching strategy, routing algorithm, and flow control mechanism. The switching mechanism plays a vital role to move the data from an input channel and place it on an output channel. Virtual cut through (VCT) and wormhole (WH) switching techniques are widely used in NoC architecture. In this paper, Wormhole and VCT technique has been proposed for Network on chip architecture and its performance is analyzed using the parameters such as area and speed. In this paper the designing and implementation of Wormhole and Virtual Cut through router have been discussed. The simulation of Wormhole system and VCT is done in Modelsim-SE as a simulation & debugging tool. The design is synthesized in Xilinx ISE 9.1i as well as in Quertus 8.1 for the packet size of 16 bits (0-15) on the platform of family automotive spartan2 for device-XC2S200, PQG208 package and speed -5.

Transformer Health Condition Monitoring Through GSM Technology[ ] [References]


Transformers are a vital part of the transmission and distribution system. Monitoring transformers for problems before they occur can prevent faults that are costly to repair and result in a loss of service. Current systems can provide information about the state of a transformer, but are either offline or very expensive to implement. Transformers being the essential part of power transmission system are expensive, as is the cost of power interruptions. Because of the cost of scheduled and unscheduled maintenance, especially at remote sites, the utility industry has begun investing in instrumentation and monitoring of transformer. On-line transformer diagnostics using conventional technologies like carrier power line communication, Radio frequency based control system, and Supervisory control and data acquiring systems, Distributed control systems and Internet based communications are having their own limitations. GSM is an open, digital cellular technology used for transmitting mobile voice and data services. This project objective is to develop low cost solution for monitoring health condition of remotely located distribution transformers using GSM technology to preent premature failure of distribution transformers and improving reliability of services to the customers. An Embedded based hardware design is developed to acquire data from electrical sensing system. It consists of a sensing system, signal conditioning electronic circuits, advanced embedded hardware for middle level computing, a powerful computer network for further transmission of data to various places. A powerful GSM networking is designed to send data from a network to other network for proper corrective action at the earliest. Any change in parameters of transmission is sensed to protect the entire transmission and distribution. The performance of prototype model developed is tested at laboratory for monitoring various parameters like transformer over load, voltage fluctuations, over temperature, oil quality and level etc.

Voice over IP Mobile Telephony Using WIFI[ ] [References]


Voice telephony over mobile is currently supported at a cost using service provider such as GSM, or using IP service provider at cheaper cost. The purpose of this research is to design and implement a telephony program that uses WIFI in p2p (Peer -to- Peer) or WLAN (Wireless Local Area Network) as a means of communication between mobile phones at no cost. The software will use a correlation between current address books available in mobile phones to convert phone numbers into IP addresses. The system will allow user to make voice conversation, sending SMS (Short Message Service) as well as MMS. Inbox and outbox services, message delivery reports, and message drafts will be used for SMS and MMS management. The current system will only allow for one call per connection, and no call waiting, or conference calls. Different security services relevant for VoIP are presented and we argue that end-to-end authentication and encryption should be provided by default. For media protection we evaluate the possibility of using either SRTP or IPsec, and we examine several alternatives of how a secure VoIP call can be established. The solution we suggest is based on SRTP for media protection, S/MIME and MIKEY for end-to-end authentication and keying, and TLS for hopby- hop protection of SIP messages.

Optimization of Principal Dimensions of Radial Flow Gas Turbine Rotor Using Genetic Algorithm[ ] [References]


The choice of principal dimensions of turbine rotor for a given set of inlet design specification can be found by solving aerodynamic equations. An analytical method is indeed difficult and can be very time consuming, especially if the complete procedure has to be repeated for different cases. In view of this, numerical optimization technique can be useful tool to problems involving a large number of variables. Among the heuristics algorithms, most common and used ones are the Evolutionary algorithms, and in particular the Genetic algorithm (GA). They are most robust, since they can be used for real and discrete variables, in highly or weakly non-linear problem types. In this paper an attempt is made to solve the numerical optimization problem for radial flow gas turbine rotor using Genetic Algorithms.

Crystallographic Properties and Surface Analysis of Spin Coated YSZ Thin Films by Raman Spectroscopy, X-ray Diffraction and Scanning Electron Microscopy[ ] [References]


Yttria Stabilized Zirconia (YSZ) thin films (<10 µm) were fabricated by spin coating technique on steel (Fe/ Cr18/ Ni10). The concentration ratio of YSZ powder to solvent were varied accordingly. The effects of these variations were investigated and discussed. Using X-ray Diffraction and Raman Spectroscopy, the crystal structure of the samples were determined. The 8-YSZ thin films have cubic fluorite structure. The X-ray diffraction patterns were in agreement with the samples' Raman spectra. In the case of the 30YSZ: 70ethanol YSZ thin film on steel substrate, the Raman and XRD peaks shifted because of the stress-strain interaction between the steel and the YSZ thin film. Pores were evident on single coated substrates but were minimized using higher YSZ concentrations.

This experiment was carried out using potted plants to assess the effect of keratin-based organic fertilizer produced from microbially hydrolysed feathers on cowpea's. The fungus isolated and used for the hydrolysis of feather during the production of organic fertilizer was identified as Aspergillus niger. The results showed that the organic fertilizer was very effective on plants with soils amended with the hydrolysed feathers, as the plants exhibited better yields and productivity. Data for plant height (cm), weight of plant, number of leaves per plant and number of pods per plant were taken at weekly interval for a period of 9 weeks.. The various treatments used were 1kg/10kg of soil, 2kg/10kg of soil, 3kg/10kg of soil while 0kg/10kg served as control. Based on observation, the treated plants were less susceptibile to diseases compared to the non-treated plants. It was revealed that organic fertilizers application rate of 3kg/10kg had the highest performance in terms of growth and yield, and least susceptibility to diseases, the converse was observed for control. The result of this study was indicative that feather which is cheap, readily available and environmentally friendly offers a promising prospect in agriculture both as an organic fertilizer and in the control of disease in cowpea if applied at recommended rates and time.

Prediction Of Performance For Web Application By Performance Modeling With Jmeter[ ] [References]


Performance analysis and modeling of web application [1] allows users to record many different parameters relevant to web application's performance. Our goal is the identification of the most influential parameters which determine the factors improving performance of web-application with the help of performance modeling. We create performance model with respect to stages of SDLC as Performance problems are frequently introduced early in the design. We first identify application scenarios and performance objectives. Performance objectives can be measured in terms of response time, throughput (how much work in how much time), and resource utilization (CPU, memory, disk I/O, and network I/O).We apply performance scenarios into steps and assign performance budgets. These budgets are used to set constraints across performance objectives and this will help to predict the performance of web application.

Advertisements: Marketing & Branding-the OTHER WAY[ ] [References]


It has been observed that government of various countries/states place advertisements/claim to generate jobs for public either to improve their image/brand to lure public for votes or to make brand of their own government. It is common practice in country like India and is spreading to other countries like U.S also. PSEUDO JOB POSTINGS- PSEUDO jobs are jobs which do not exist in reality but are placed on job portals/Television/radio/print media to get attention of public, so that name of company can be placed/instilled in public mind/brain, which is a form of branding and advertisement for the company. However it has to be noted that no candidate is called for interview /test on the basis of pseudo jobs, so that public interest is not harmed in any way and sanctity of company is maintained.

Second suggestion, disappear the sensitive data (sensitive attributes) of the end users and appointments one responsible only for that data.

Experimental Determination of Thermal diffusivity of Teak Wood as a Function of Water Content[ ] [References]


The wood of teak is much used as building materials in Benin. The quest of comfort conditions in housing needs a better knowledge of thermal performance of the materials forming the walls of building structures. The goal of this study is to estimate the thermal diffusivity of teak as a function of water content using the regular state method. The analysis of the results shows that teak can be used as a good thermal insulating material which allows realizing thermal comfortable apartments in fair conditions.

Nuclear Structure Of Even-even 104-110Mo ISOTOPES[ ] [References]


From the E-Gamma Over Spin (E-GOS) curve and the energy level ratios, we have deduced that the 104-110Mo isotopes lies between the vibrational U(5) and axial deformed rotor SU(3) limits and most of them display the X(5) symmetry features. We have compared the results obtained by interacting boson model IBM-2 for the above isotopes with those of the X(5) limit and then given a clear description about the validity of the Hamiltonian parameters used in this study.

Classification And Clustering Of Brain Seizure Activity Using Wavelet Transform And Radial Basis Neural Network[ ] [References]


Electroencephalogram (EEG) is the record of the brain electrical activity and it contains valuable information related to the dif-ferent physiological and pathological states of the brain. Epilepsy is known to be the most prevalent neurological disorder in humans and seizure discharge is the main characteristics of the epilepsy. EEG is an important clinical tool for the diagnosis and monitoring of seizures. Epileptic seizure occurs irregularly and unpredictably manner due to temporary electrical disturbance of the brain. The aim of this project is Epileptic seizure detection in multichannel EEG. This paper presents a novel method for automatic epileptic seizure detection, useing recurrent rates derived from discrete wavelet transform in combination with a radial basis function neural network for classification and clustering of the pattern feature of EEG signals. The output of the neural network aids in finding existence or absence of seizures in the EEG data. We have used discrete wavelet transform (DWT) of Daubechie's wavelet order 4 to decompose the EEG signal at different levels in extracting approximation and detail coefficients. We have evaluated a unique dynamical parameter (recurrence rate) from the wavelet co-coefficients of EEG of different subjects (normal and epileptic). The recurrence rate has been used in a radial basis function neural network for seizure detection. The performance of the network has been evaluated in terms of the accuracy, specificity and sensitivity detecting in unknown EEG time series.
