Stress Analysis of Prithvi Missil Wing Subjected to Aerodynamic Forces
The stress problem of Prithvi missile wing is investigated .
The analysis is carried out by the finite element method by using the ASKA software package. Finite element analysis is carried out for pressure loading, and thermal loading arising from aerodynamic heating . The,analysis for pressure loading indicates that there is stress concentration at the wing root region results obtained for various cases of this loading are presented and discussed. The distortion of the wing produced by aerodynamic heating has also been displayed
Centralization of Educational Resources in UGC Funded Institutions: A proposal for Open Online Catalogue
Reducing duplication of works across library platforms is a highly discussed subject. Bringing together different bibliographic records of various types of documents (books, journals, theses and other types of materials) that are situated in particular libraries of UGC funded institutions would largely help in avoiding duplication efforts. In India, there are handful of such initiatives are taking place to make information services as centralized on a common platform and several similar activities are under work in progress. In-line with such developments having a common integrated centralized Online Public Access Catalogue (OPAC) across higher edcation sector is a must. In this article authors have made an attempt to put forward a proposal for developing a centralized OPAC for UGC funded institutions
Polynomial Kernels for Generalized Domination Problems
In this paper, we study the parameterized complexity of a generalized
domination problem called the [] Dominating Set problem. This
problem generalizes a large number of problems including the Minimum Dominating
Set problem and its many variants. The parameterized complexity of the
[] Dominating Set problem parameterized by treewidth is well
studied. Here the properties of the sets and that make the
problem tractable are identified [1]. We consider a larger parameter and
investigate the existence of polynomial sized kernels. When and
are finite, we identify the exact condition when the [] Dominating Set problem parameterized by vertex cover admits polynomial
kernels. Our lower and upper bound results can also be extended to more general
conditions and provably smaller parameters as well.Comment: 19 pages, 6 figure
Self-actualization from an Eastern Perspective—A Preliminary Exploration
Growth of the branches of humanistic and positive psychology has brought in a paradigm shift in the understanding of human nature and behavior from the reductionistic and mechanistic perspectives. Emphasis on the study of the self necessitates greater use of a qualitative subjective methodological framework. In this respect, the current Western approach falls short in front of the Eastern philosophy, which has an array of such procedures and methodologies, which practitioners of humanistic and positive psychology are now exploring. The Indian systems of thought elaborate on the means to realizing or knowing the true nature of the self within, through the multi-faceted and individualized process of Yoga. Alternative systems of Yoga are provided that could be practiced by individuals based on their subjective preferences and suitability. The major alternatives that have been identified are Bhakti, Jnana, Karma and Raja Yoga. In this context, the present study is a pilot attempt to explore self-actualization among practitioners of two paths of Yoga i.e. Bhakti Yoga and Jnana Yoga. The opinions and beliefs of the practitioners on variables related to the self and its actualization, as also their world-views are explored. Implications on personality, distinguishing characteristics and the functioning of self are proposed, to enable an individual to adopt a suitable path
Assessing Risks in Two Projects: A Strategic Opportunity and a Necessary Evil
McFarlan\u27s IT Project Risk Assessment Framework (Applegate, et al., 1996), identifies three main areas of IT project risk: project size, project structure, and technology familiarity. According to this framework, if two IT projects are of similar size, a project which is designed primarily around emerging technologies will entail significantly higher risks than a project which is designed primarily around traditional technologies. This paper analyzes two comparably-sized IT projects. One - a telemedicine initiative at Fletcher-Allen Health Care in Vermont -- is designed primarily around emerging technologies. The other - the year 2000 compliance program at the New York Metropolitan Transportation Authority (MTA) - is focused primarily on fixing and testing existing systems on traditional platforms. Our assessment identified two additional salient criteria which, when applied to the two projects revealed higher risks at the MTA. These criteria are time constraints (i.e., the immovable deadline of the year 2000) and system interdependence (i.e., the need for applications to share data with other applications, both within the MTA and with numerous external parties). When these two factors are taken into account, it becomes evident that Year 2000 initiatives represent far higher project risks than the emerging technology projects that are considered to be on the bleeding edge
Identification of polymorphic microsatellite loci in the queenless, ponerine ant Diacamma ceylonense
Diacamma ceylonenseis a queenless, ponerine ant whose colonies are headed by a single, mated, egg-laying worker referred to as the gamergate. Thus, new colonies are a result of dispersal by wingless gamergates. This is expected to influence patterns of colony dispersal and spatial distribution of genetic variablity. In order to facilitate the study of population genetic structure we have identified six unique, polymorphic, microsatellite loci. We have used fluorescence tagged primers to detect polymorphism at these loci
