 Abstract

The unsteady two-dimensional flow of a non-Newtonian fluid over a stretching surface having a prescribed surface temperature in the presence of radiation and suction/injection is investigated. The Casson fluid model is used to characterise the non-Newtonian fluid behaviour. Similarity transformations are employed to transform the governing partial differential equations into ordinary differential equations. The transformed equations are then solved numerically by Bvp4cMatlab olver. The flow features and heat transfer characteristics for different values of the governing parameters viz. unsteadiness parameter, Casson parameter, radiation parameter, Prandtl number and suction/injection parameter are analyzed and discussed in detail. Fluid velocity initially decreases with increasing unsteadiness parameter and temperature as well as concentration decreases significantly due to unsteadiness. The effect of increasing values of the Casson parameter is to suppress the velocity field. But the temperature and concentration is enhanced with increasing Casson parameter. Both the momentum and thermal boundary layer thicknessdecreases in an increasing suction/injection parameter. Magnitude of skin-friction reduces,but the rate of heat transfer increases with raising the suction/injection parameter.

 Abstract

In this age of globalization the service sectors shows great promise as one with tremendous growth potential.. In this regard, employee stress is perhaps the most contributing factor to work performance. This paper attempts to find the impact of work stress on performance among the managers executives in three service sectors namely hospital, hotel and bank in Nilgiri district . The data was collected from 490 respondent and was analyzed statistically using SPSS 19 software. The statistical tools used were independent sample t-test, one way ANOVA, and Pearson bivariate correlation.The findings of the study revealed that tourism employees face more stress when compared to hospital and bank employees.. The results confirmed that job stress had a negative effect on job performance. Hence organization needs to focus on these stress creating factors and try to minimize or overcome the same.

 Abstract

Web applications are one of the most prevalent platforms for information and services delivery over Internet today. As they are increasingly used for critical services, web applications become a popular and valuable target for security attacks. Although a large body of techniques has been developed to fortify web applications and mitigate the attacks toward web applications, there is little effort devoted to drawing connections among these techniques and building a big picture of web application security research. This paper likewise gives an outlined examination of talked about assaults against picked critical parameters. Likewise, observational information about assaults by means of Emails over some undefined time frame is additionally displayed. The paper closes by saying the need of such studies and research openings here.

 Abstract

GDP growth in Indian economy is losing its momentum and the economy is passing through a slowdown phase. It fell sharply from 9.2 percent in Q4 FY 2017 to 5.7 percent in Q1 FY 2018, and recovered a little by 0.6 percent in Q2. Falling numbers are wakeup calls for the policy makers to initiate reviving measures, because economic growth matters a lot for India, which is emerging as an economic power amidst a lot of structural issues. The present study explores the recent macro-economic developments in the economy closely and examines the applicability of different policies.

 Abstract

Detectors is used in Process Industry to Detect Fire or gas release and automatically Initiate audible and visual alarm in the respective designated Emergency response area, Control room. They are designed to operate continuously expect for periods of maintenance or fault repair. By early Detection of a potential hazardous event and carrying out predetermined actions to mitigate the effects, Detector helps to ensure 1. Protection of personnel, protection of environment, protection of plant, In the absence of useful Flame detection, Process Industry is vulnerable to a potentially significant and disproportional increase of Main hazards: (1) Fires can basis of injury to people and have the probable to raise the hazard to adjacent vessels, piping or equipment. This paper explained how to set up optimization simulation and How to interpret the Coverage, Fitness for Flame gas Detector by Using Detect3D software. Also Study of pre-incident planning assessment by considering the scenario of Pin hole leak & Fire in downstream HP line of vessel.

 Abstract

There is a vast usage of binary addition in digital circuits as it is the basic arithmetic operation and it became indispensable in most of the digital systems counting ALU, microprocessors and DSP. Adders are the fundamental building blocks in digital integrated circuit based designs. Ripple Carry Adder (RCA) gives the most solid design but takes more computation time. The time crucial applications employ Carry Look-ahead scheme (CLA) is used to derive fast results but they lead to increase in area. Carry Select Adder is a concession between RCA and CLA in terms of area and delay. This paper shows a great vision on the design analysis of carry select adder based on Multiplexer using Verilog. The delay (9.069ns), power (20.98mW) is minimized and total coverage is 100%. The proposed architecture of carry select adder is simulated and verified in ModelSim10.1e, synthesized in Xilinx ISE14.7 and power analyzed in Quartus II9.1.

 Abstract

Filariasis , is a major public health problem in tropical countries like India, China , Indonesia, Africa & the far east. We are describing a case of W. bancrofti presenting as a subcutaneous swelling which is an unusual presentation. Aspiration cytology often helps in demonstration of filaria from uncommon diverse areas like breast, thyroid, effusion fluid, soft tissue swellings, etc. In endemic area diagnosis of filariasis should always kept in mind , even in asymptomatic cases, which can lead to correct diagnosis and prompt patient management.
