USE OF SMART PHONES FOR ACADEMIC PURPOSE BY FACULTY MEMBERS OF BHARATHIAR UNIVERSITY

Purpose: To study the use of smart phones for academic purpose by faculty member of Bharathiar university. The Smartphone has become an indispensable device for effective communication and information-gathering. Aim: The study aims to assess the level of use of smart phones for academic purpose by the faculty members of Bharathiar University. Design/Methodology/Approach: Data has been collected through questionnaire from faculty members of Bharathiar University using a random sample technique. The data were analyzed using SPSS and MS Excel. Findings: The finding of the study shows that everybody uses a Smartphone. The top three reasons for using a Smartphone are communication, browsing, and academic purpose. Majority of the respondents reported that they use smart phones for reading academic papers. Overall, the significance of smart phones helps to generate and exchange information, improve the learning and assist in projects

Socio-economic Impact Assessment of Livelihood Security in Agriculture, Animal Husbandry and Aquaculture on the Tsunami-hit Lands of Andaman

Indian subcontinent is highly vulnerable to major natural disasters such as earthquakes, cyclones, floods, droughts, landslides and bushfires. Tsunami, which is a recent addition to this list, had occurred in the early morning of 26th December 2004, after a massive earthquake of 9.2 magnitude on the Richter scale in Andaman & Nicobar islands, resulting in the submergence of large area of farmland, and subsequent drying up of water bodies. It caused moisture stress for the standing crops, livestock and fisheries and affected the livelihood of the people to a large extent. In this context, the present study has been carried out to make the socio-economic impact assessment of livelihood security in agriculture, animal husbandry and aquaculture on the tsunami-hit lands of Andaman. Data have been collected from 150 sample respondents and the survey has been conducted for two periods, pre-tsunami and post-tsunami. The results have indicated that tsunami has ravaged the households, standing crops, farm inputs such as seed, feed and implements, livestock and poultry population, their sheds, fish ponds, etc., thereby affecting the basic livelihood security of the people in Andaman. The rehabilitation measures taken by the government and NGOs have improved their livelihoods by reviving agriculture considerably in the subsequent years and by creating employment opportunities in various farm and non-farm activities. The paper has suggested creating profitable livelihood security to vulnerable sections of the society in the existing socio-economic penury with holistic intervention of the community, government and NGOs.Agricultural and Food Policy,

Durability Map for The Friction Stir Welding Tools with Flat Faced Pins

In friction stir welding, tools made with flat faced pins deliver comparatively higher strength joints than circular pins. However, its non-axisymmetric cross section about the rotational axis results in fluctuating stress along its surface that leads to premature tool failure. This requires a systematic definition for process parameter selection domain based on the number of flat faces in the pin to improve tool life. Temperature dependent strength of the material to be joined in the stir zone is the only source of opposing force for the tool movement. To predict opposing force, temperature gradient developed by the different levels of process parameters in the stir zone is numerically quantified with an experimentally validated model. Based on the estimated temperature, maximum stress acting on the tool pin is quantified with a remodified temperature dependent analytical model. The effect of increase in process temperature on the strength of the weld joint is experimentally analysed through the investigation of change in hardness value in heat affected zone. Obtained results are used to develop tool durability maps for tools with flat faced pin in a domain on which higher and lower limits are fixed by considering satisfactory level of joint strength and tool life respectively. These maps provide flexibility in the parameter selection with an acceptable level of compromise in joint strength or in tool life based on the quality requirement of weld joint

User interface design and development: the role of open source systems

Open Source movement has tremendously influenced Information industry, in particular the Digital Library Environment where the Information Systems and services are inevitable. This has helped the Library and Information Centers in developing User Interface to render web based services to the patrons. Wherever the network infrastructure and the target users are in place, the design and development of IR user interface using Open Source system for a specific application is very much possible. This paper highlights the role of Open Source Systems in detail and explains a prototype IR User Interface which was developed in-house at Indira Gandhi Centre for Atomic Research, Kalpakkam

An Algorithm on Generalized Un Sharp Masking for Sharpness and Contrast of an Exploratory Data Model

In the applications like medical radiography enhancing movie features and observing the planets it is necessary to enhance the contrast and sharpness of an image. The model proposes a generalized unsharp masking algorithm using the exploratory data model as a unified framework. The proposed algorithm is designed as to solve simultaneously enhancing contrast and sharpness by means of individual treatment of the model component and the residual, reducing the halo effect by means of an edge-preserving filter, solving the out of range problem by means of log ratio and tangent operations. Here is a new system called the tangent system which is based upon a specific bargeman divergence. Experimental results show that the proposed algorithm is able to significantly improve the contrast and sharpness of an image. Using this algorithm user can adjust the two parameters the contrast and sharpness to have desired output
