Power optimization is the paramount technique to reduce the power consumption in digital VLSI circuits. It is analyzed through relative analysis of the conventional FPGA routing technique with the proposed low-power FPGA routing technique. The proposed technique works in three various modes namely low-power, high-power and sleep mode. The FPGA switching circuitry shows reduced leakage power and area overhead in low power versus high speed mode. The conventional circuitry is reconfigured to surpass the existing method in terms of power and area. The simulation results show that the power dissipation in the proposed system is less than the existing system. Source

In this study, aluminium AA6063 plate of 6mm thickness plate were welded by friction stir butt joint using different tool probe of Square and pentagon with constant parameter of rotational speed transverse speed and axial force of 1500 rpm, 35 mm/min and 5kN.The effect of welding parameter was evaluated in different mechanical properties of hardness distribution and tensile properties for axial weld zone. The significant optimal transverse feed is achieved with high weld quality and excellent joint properties when compared to square tool. In this square tool gives the excellent result was obtained both tensile strength as well as hardness in order to improve productivity. © (2015) Trans Tech Publications, Switzerland. Source

This work investigates the effect of variable compression ratio on the performance and emission characteristics of a single cylinder, direct injection diesel engine powered by waste plastic pyrolysis oil blended with diethyl ether. Experiments were conducted with different compression ratios of 15, 16, 16.5 and 17 at various load conditions with a constant speed of 1500 rpm. Two blends of WD05 and WD10 on volume basis have been tested and compared with respect to waste plastic pyrolysis oil and diesel fuel. Brake thermal efficiency was slightly higher with respect to diesel fuel. It was observed that the exhaust emissions are significantly decreased with increase in diethyl ether waste plastic pyrolysis oil (DEE-WPPO) at full load conditions. By increasing the compression ratio from 15 to 17, produces lower smoke opacity, hydro carbon (HC), Oxides of nitrogen (NOx) and carbon monoxide (CO) respectively. Source

Construction industry has accomplished extensive growth worldwide particularly in past few decades. For a construction project to be successful, safety of the structures as well as that of the personnel is of utmost importance. The safety issues are to be considered right from the design stage till the completion and handing over of the structure. Construction industry employs skilled and unskilled labourers subject to construction site accidents and health risks. A proper coordination between contractors, clients, and workforce is needed for safe work conditions which are very much lacking in Indian construction companies. Though labour safety laws are available, the numerous accidents taking place at construction sites are continuing. Management commitment towards health and safety of the workers is also lagging. A detailed literature study was carried out to understand the causes of accidents, preventive measures, and development of safe work environment. This paper presents the results of a questionnaire survey, which was distributed among various categories of construction workers in Kerala region. The paper examines and discusses in detail the total working hours, work shifts, nativity of the workers, number of accidents, and type of injuries taking place in small and large construction sites. © 2015 S.

The cloud computing is visualized as next generation framework for IT enterprise. The technology shifts the software and database to huge fixed central centers where the data management and services are not trustworthy. The technology gives rise to challenges in security which is of prime focus. The study focuses on ensuring security in storing data into cloud system. The third party auditor is allowed on behalf of cloud user for verifying the integrity of dynamicity of data stored into cloud. The third party auditor removes the participation of users through auditing of whether the data hoarded into cloud is certainly intact which is important in achieving the economy for cloud computing. The dynamicity in data is achieved via general forms of data like chunk alteration inclusion and removal which is a significant because the services in cloud systems are not limited for archiving the data. The conventional schemes on assuring data integrity do not support public audits or data dynamicity. The problems in identifying the complexity and security with updates in dynamic data from the earlier works and paved a way for designing a verification scheme for aggregating the above features. In order to achieve data dynamics and for supporting multiple auditing tasks a technique for combining signature are proposed which performs the task of auditing continuously. The security and performance analysis of the proposed scheme are effective and secure. © Medwell Journals, 2016. Source
