Fabrication and Characterization of A356.2-Rice Husk Ash Composite using Stir casting technique
D.SIVA PRASAD,,Dr .A. RAMA KRISHNA
International Journal of Engineering Science and Technology , 2010,
Abstract: Fabrication and characterization of A356.2 alloy reinforced with rice husk ash (RHA) particles are dealt in the present study. The metal matrix composites (MMC’s) were prepared by addition of 2, 4 and 8 wt% RHA particulates through stir casting technique. Scanning electron microscope equipped with energy dispersive X-ray analyzer is used for micro structural characterization and the presence of silicon particles in the composites. Mechanical properties like density and hardness were measured for the composites. As the percentage of RHAparticles increases, the density of the composites decreases and there is slight increase in the hardness were observed.

Journal of Medical and Allied Sciences , 2011,
Abstract: In order to understand the mechanism of molecular interactions at active sites of trafficking protein particle complex (TRAPPC) subunit 3-like protein (Accession number Q5T215) homology modeling and docking studies were taken up. We generated a three-dimensional (3D) model of target protein based on the Crystal structure of Human BET3 protein (PDB code 1SZ7) using modeller software. Under the process of homology modeling 25 models were generated, and the model having the lowest modeler objective function value was chosen for further assessment. The generated model was assessed and validated using PROCHECK software and found to be reliable.With the generated model, we carried out a flexible docking study using the FlexX docking tool available on the Sybyl Software in order to find better antagonist site for drug binding. We carried out a flexible docking with the Palmatic acid and Donepezil as ligands; these were found to bind at LEU87, LYS84 and THR90 residues on given generated protein in our studies. We therefore concluded that the above mentioned residues were the key residue sites for ligand binding showing strong hydrogen bonding contacts.The target protein is more prevalently seen in the amygdala region of brain which forms one of the key subunit of TRAPP complex. As per functional similarity with BET3, target protein might play key role in trafficking abnormally folded A-beta and tau proteins along endoplasmic reticulum to Golgi apparatus there by leading to formation of senile plaques in various regions of brain, whose accumulation causes Alzheimer’s disease.
SANKEERNA: A LINEAR TIME, SYNTHESIS AND ROUTING AWARE, CONSTRUCTIVE VLSI PLACER TO ACHIEVE SYNERGISTIC DESIGN FLOW
Santeppa Kambham,Siva Rama Krishna Prasad Kolli
International Journal of Advances in Engineering and Technology , 2012,
Abstract: Standard cell placement is a NP complete open problem. The main objectives of a placement algorithm are to minimize chip area and the total wire length of all the nets. Due to interconnect dominance, Deep Sub Micron VLSI design flow does not converge leading to iterations between synthesis and layout steps. We present a new heuristic placement algorithm called Sankeerna, which tightly couples synthesis and routing and produces compact routable designs with minimum area and delay. We tested Sankeerna on several benchmarks using 0.13 micron, 8 metal layer, standard cell technology library. There is an average improvement of 46.2% in delay, 8.8% in area and 114.4% in wire length when compared to existing placement algorithms. In this paper, we described the design and implementation of Sankeerna algorithm and its performance is illustrated through a worked out example.

Abstract: To create standards-based secure access to patient’s personal data and medical records by using RFID tags and Web Service with the help of hardware kit. This system uses Web service interfaces to support standard Electronic Health Records for patient record interoperability. Customers can view and update their personal medical information via the web site, which seamlessly sync with one another. Because the system is built on Web services, it is easy to update, adapt and grow. Trying to identify an unconscious patient or patient who is unable to communicate can lead to delays in treatment. With this system emergency departments improve efficiency while enhancing the level of patient care. This project uses the hardware kit to get the patient id. The hardware kit will send the patient id to the serial port of the system. Hence tracking and monitoring of patients, their case sheets and medical equipments can be efficiently carried out. However, the reality of RFID adoption is far behind earlier expectation. This study reviews the literature on RFID applications in healthcare based on a formal research framework. We aim to identify current opportunities, potential benefits and adoption barriers. Our study shows that most care providers indicated that RFID to be functional and useful in asset tracking and patient identification. Major barriers to RFID adoption in healthcare include prohibitive costs, technological limitations, and privacy concerns. Although RFID offers healthcare practitioners advantages to enhance clinical practice, better designed RFID systems are needed to increase acceptance and proper use of RFID in healthcare.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.1010068
Abstract: The effect of various process parameters like welding current, torch height, welding speed and plasma gas flow rate on front melting width, back melting width and weld reinforcement of plasma arc welding on aluminum alloy is investigated by using factorial design approach. Variable polarity plasma arc welding is used for welding aluminum alloy. Trail experiments are conducted and the limits of the input process parameters are decided. Two levels and four input process parameters are chosen and experiments are conducted as per typical design matrix considering full factorial design. Total sixteen experiments are conducted and output responses are measured. The coefficients are calculated by using regression analysis and the mathematical models are constructed. By using the mathematical models the main and interaction effect of various process parameters on weld quality is studied.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2012, DOI: 10.4236/jmmce.2012.112010
Abstract: Nickel alloys had gathered wide acceptance in the fabrication of components which require high temperature resistance and corrosion resistance, such as metallic bellows used in expansion joints used in aircraft, aerospace and petroleum industry. In the present paper an attempt is made to study various weld quality characteristics like weld bead geometry dimensions, micro hardness, microstructure, grain size and tensile properties of Pulsed Current Micro Plasma Welding of Inconel625sheets. Weld joint was prepared by fusing the two parent metals of Inconel625 sheets. Square butt joint is used and welding was carried out using Pulsed DCEN, without filler wire. Peak current, back current, pulse and pulse width are considered as the main influential input variables during the welding.

Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.37017
Abstract:

Many researchers have studied the effect of corruption on Foreign Direct Investment (FDI) and majority of them have come to the conclusion that higher levels corruption in a country deter FDI. This paper is a case-based comparative study of the effect of corruption on FDI in China and India. Corruption in India has negatively affected FDI, whereas that is not true in China. This study finds that while corruption does affect FDI inflows into a country, the effect also depends on nature of corruption and not only on size of corruption.

An Effective Solution to Reduce Count-to-Infinity Problem in Ethernet
D. Ganesh,Venkata Rama Prasad Vaddella
International Journal of Computer Science Issues , 2010,
Abstract: Ethernet is currently the most popular networking technology because of its high performance, low cost and ubiquity nature. Ethernets rely on the dynamic computation of a cycle-free active forwarding topology. For that it uses rapid spanning tree protocol. Unfortunately, it exhibits count-to-infinity problem that may lead to forwarding loops under certain network failures. These consequences are considered serious since network can become highly congested and even packet forwarding can fail. In this work, a simple and effective solution to reduce count-to-infinity problem, called RSTP with epochs is proposed. This eliminates the count-to-infinity induced forwarding loop and improves the convergence time.
