Dayananda Sagar College of Engineering , started in 1979, was founded by Sri R Dayananda Sagar and is run by the Mahatma Gandhi Vidya Peeta Trust. It is on 28 acres of land on a hillock in Kumaraswamy Layout, Bangalore South. Research programmes sponsored by AICTE, AR&DB, KSCST are undertaken. The college organizes seminars, workshops, teaching talks, sports and extracurricular activities. With 1850 systems, student information system and several digital classrooms, it was one of the first education centers to go WiFi in the country. Wikipedia.

Micro array is a powerful Technology, that is useful in analyzing expression levels of thousands of genes simultaneously, which is important in biological and medical investigation. Micro array image analysis consists of three stages: gridding, segmentation of spots and finally Quantification. Segmentation is a process of separating the foreground signal from the background and it is a crucial stage in the analysis. In this paper we propose a method for performing accurate spot segmentation of noisy micro array images. The k-means classification method is refined, so that classification of foreground / background is accurate which works best even for noisy spots, weakly expressed spots and spots with artifacts. Comparison of the proposed method with existing methods shows promising results.

This paper focuses on the optimal power flow solution and enhancement of system performance without sacrificing the security of the system via optimal location and optimal sizing of Thyristor Controlled Series Compensator (TCSC) when the system is operating under normal and network contingency conditions. The paper presents a secured optimal power flow solution by integrating TCSC with the optimization model developed under normal and contingency cases. The optimization model developed in this paper is solved by using linear programming method. New indices called Thermal Capacity Index (TCI) and Contingency Capacity Index (CCI) are proposed for placing the TCSC at appropriate location under normal and network contingency conditions respectively. Once the location to install TCSC is identified, the optimal setting of TCSC is determined through the software code written in MATLAB. The proposed approach is carried out on 6-bus, IEEE 14-bus and IEEE 118-bus test systems and the simulation results are presented to validate the proposed method. © 2011 Elsevier Ltd.

This paper aims to explain the basic physics concept of friction in a better way as it highlights the behavior of the body during motion considering the effect of friction. The paper combines physics and mathematics with equations and graphs. The investigation focuses the characteristics of a body in motion by keeping eye on friction by making graphical approach and also by quantitative study. The research establishes certain facts and points on friction. It establishes certain equations which helps the concept to understand better. A simple demonstration has been made for better understanding the concept. MATLAB software is used to draw the graphs. An algorithm has also been framed for step by step understanding and bringing clarity to the concept. © Springer International Publishing Switzerland 2015.

This paper presents the multi-input renewable source inverter which is interlinked with AC grid link. Photovoltaic and fuel cell energy sources are connected to the current fed half bridge converters, which perform soft switching action without any additional snubber circuit. Series connection of the HF transformer secondary terminals provides further extension of energy sources converters. A simple H-bridge inverter is being used at final stage which is linked to grid line. Analysis and design of the proposed multi-input renewable source inverter has been presented. Simulation analysis is done for 200watts inverter using simulation tool PSIM 9.0.3 to verify the design considerations and analysis. © 2015 IEEE.

A compact model for the quasi-ballistic cylindrical gate-all-around MOSFET was developed by supplementing the ballistic framework previously disclosed by us with an original energy quantization model. The ballistic mobility is calculated for both degenerate and nondegenerate conditions under collision-free transport. The conventional device electric current showed a remarkable decrease compared with the quasi-ballistic current. The results so obtained have been compared with those obtained from Sentarus device simulator and are found to be in good agreement. Copyright © 2015 Trans Tech Publications Ltd, Switzerland.
