Dr. Nirmal Kumar Kund
Abstract - Familiar air cooling exercise is not applicable for high heat flux electronics instruments. For that, the thermal management of electronics module is very much important to its smooth operation. The present study involves an electronics module kept horizontally at the base, inside a square shaped chamber filled with nanofluid as coolant. Three different water based nanofluids, specifically Water-TiN, Water-TiC and Water-Fe, are considered as coolants in the present investigations. The numerical studies are performed to obtain the heat transfer behavior of electronics module for maintaining its temperature within the safe limit. For that, a 2D numerical model is being developed which also includes thermal buoyancy. The continuity, momentum and energy equations are solved to predict the thermal behavior. Simulations are conducted to predict the temperature fields and temperature contours. The trends of results are along the expected lines. Simulation results predicted with three different water based nanofluids are analyzed and compared for realizing the relative importance of the stated nanofluids. The key model parameter considered is heat flux of 70 W/cm2 associated with the electronics module. The Water-TiC is observed as the nanofluid providing relatively higher cooling effect to electronics module with no such failure on account of bulk temperature.

8 Design of Low Power and Area Efficient 256 Bits Shift Register Using Pulsed Latches
T. Mounika, G. Mahesh Kumar
Abstract - In low-power digital design, especially in shift registers, flip-flops (FF) plays a significant role. In move enrolls, the power utilization of framework clock is assessed to be half of the general framework control. This paper proposes a low-power and territory proficient move enlist utilizing computerized beat locks. The region and power utilization are lessened by supplanting flip-flops with beat hooks. This technique takes care of the planning issue between beat locks using various non-cover deferred beat clock motions rather than the ordinary single beat clock flag. A 256-piece move enroll utilizing beat hooks was created utilizing a 0.18um CMOS process with VDD = 1.8V. The proposed move enroll spares 37% region and 44% power contrasted with the traditional move enlist with flip-flops. In advanced circuits, a move enroll is a course of flip lemon, having a similar clock, in which the yield of each flip-tumble is associated with the "information" contribution of the following flip-slump in the chain, bringing about a circuit that movements by one position the "bit exhibit" put away in it, moving in the information show at its information and moving out the last piece in the cluster, at each progress of the clock input. All the more by and large, a move enroll might be multidimensional, to such an extent that its "information in" and organize yields are themselves bit exhibits: this is executed basically by running a few move registers of a similar piece length in parallel.

Abstract - The waste asbestos sheet used in concrete making leads to greener Eco-Friendly environment. Use of waste asbestos sheet in concrete is an interesting possibility for economy on waste disposal sites and for conservation of natural resources. This project examines the possibility of using waste asbestos sheet as a replacement in coarse aggregate for a new concrete preparation. Natural coarse aggregate partially replaced (0%,5%, 10%, and 15%) with waste asbestos sheet. Compressive strength and flexural strength up to age of 28 days are compared with those age of concrete made with natural coarse aggregates. Fineness modulus, specific gravity, moisture content, water absorption for aggregate are studied. The test results indicate that it is possible to manufacture concrete containing waste asbestos sheet with characteristics similar to those of natural coarse aggregate concrete provided that the percentage of waste asbestos sheet as coarse aggregate is limited to 10-15%, respectively.

Ajit B. Kanase, Sachin R. Gengaje
Abstract - Since electric distribution network reconfiguration accounts for various operational constraints it is a combinatorial optimization problem. This paper presents a fuzzy multi-objective approach to improve the efficiency of radial electric distribution network by reducing active power loss and node voltage deviation. Multiple objectives considered are minimizing the active power loss and minimizing node voltage deviation, subject to a radial network structure in which all loads must be energized. Evaluations of imprecise nature of these two objectives are modeled with fuzzy sets. Depending on relative importance weighing factors can be assigned to each objective. The effectiveness of the proposed method is tested with IEEE 33 bus radial distribution system for minimization of system active power loss and reducing node voltage deviation.

K. Roopa Reddy, Akhila .V
Abstract - The induction motor drive set with B4 inverter was proposed for reducing the inverter cost, however, the instability in the current due to the fluctuations of dc link voltage is the major drawback .Keeping the factors in view, the torque and stator flux were controlled in a predictive way. Balancing the currents is achieved forcefully by stator flux control method which leads to better results. The effects of the voltage offset due to the two dc-link capacitors are also modeled and controlled in a best possible way using predictive control. To enhance the results of the cost function instead of PI controller, the fuzzy logic controller has been used which helped in giving a good dynamic performance by creating good torque reference values. The simulations of proposed techniques were carried out in the MATLAB/Simulink environment. The torques, as well as stator flux ripples, were comparatively less in the fuzzy logic controller using predictive model.

22 Multimedia Mining: Multimedia World
N.Sivakumar, V.Vidhya, R. Selvapriya
Abstract - For many years, statistics have been used to analyze data in an effort to find correlations, patterns, and dependencies. However, with advancement in technology, more and more data are available, which greatly exceed the human capacity to manually analyze them. Before the 1990's, data collected by bankers, credit card companies, department stores and so on have little used. But in recent years, as computational power increases, the idea of data mining has emerged. Data mining is primarily used today by companies with a strong consumer focus - retail, financial, communication, and marketing organizations. It enables these companies to determine relationships among "internal" factors such as price, product positioning, or staff skills, and "external" factors such as economic indicators, competition, and customer demographics. Data mining software analyzes relationships and patterns in stored transaction data based on open-ended user queries. Several types of analytical software are available: statistical, machine learning, and neural networks. Data mining, the discovery of new and interesting patterns in large datasets, is an exploding field. Media mining refers to a technique whereby a user can retrieve, organize, and manage media data. Audio mining is a technique by which the content of an audio signal can be automatically analysed and searched. Video Mining is changing the way in-store insights are gathered and applied by automating the collection of shopper behavior and segmentation data. Image mining has led to tremendous growth in significantly large and detailed image databases. The discovery by computer of new, previously unknown information, by automatically extracting information from a usually large amount of different unstructured textual resources. In Text Mining, the input is free unstructured text, whilst web sources are structured. With the exponential increase in media data on personal computers and the Internet, it is critical for end users to efficiently manage metadata to find the information they are looking for. This paper is an outcome of the study on data, media, audio, video, image, text and web mining from exiting literature.

24 Numerical Studies on Supersonic Turbulent Flow over a Backward Facing Sharp Edge Step Using Hybrid RANS-LES
Dr. Nirmal Kumar Kund
Abstract - In the present study, a two dimensional numerical model is developed to investigate supersonic turbulent fluid flow over a backward facing sharp edge step by using both RANS (relating to the standard k-e model) and hybrid RANS-LES (pertaining to the Spalart-Allmaras model involving viscosity-like variable) models. The model also involves additional important factors namely production, diffusion and destruction terms besides the very common aspects related to the present research problem. The numerical simulations are performed using the stated turbulence models with the inflow free stream Mach number of 2.5 along with the free stream pressure and velocity of 15350 N/m2 and 651.9 m/s2, respectively. The simulation predictions are compared with the corresponding experimental results available in the literature. Even though the simulation predictions from both RANS and hybrid RANS-LES models yield satisfactory results, however, the hybrid RANS-LES model gives fairly better and consistent results over the RANS model (which provides very good results within the vicinity of the wall region only) throughout the entire flow region and hence, only the hybrid RANS-LES is considered for further investigations. It is also noticed that the sudden viscous layer separation is the prime cause for the generation of reattachment shock. In addition, the uneven pressure recovery is owing to the sudden expansion flow over the sharp edge step. Further, the sudden expansion flow increases the intensity of the shock which leads to uneven flow behaviours. Definitely, the present test case results are very highly beneficial to understand the flow characteristics of supersonic turbulent fluid flow over the backward facing sharp edge step flows.
