ASSEMBLY BY PRESTRESSED OR HIGH-STRENGTH BOLT[Full-Text ]
CHAOUFI.ALI, AHMED TAFRAOUI

The analytical method provides a very good approximation of the tightening of a bolted assembly. Consequently, one can be satisfied with a fast analytical calculation to rather precisely check the tightening of a bolted assembly. A model finite element is hardly more precise at least of a point of considering total. One could still look further into these problems by determining in experiments the constraints in the screw and the part of a pre stressed bolted assembly. It would be also interesting to see more precisely, how evolves locally the constraints in the part and the screw.

A Cayley graphs for Symmtric group on Degree four[Full-Text ]
S:V IJAY AKUMAR, C:V:R:HARINARAY ANAN

In this paper, we determine all of subgroups of symmetric group S4. First, we observe the multiplication table of S4, then we determine all possibilities of every subgroup of order n, with n is the factor of order S4. We found 30 subgroups of S4. The diagram of Cayley graphs of S4 is then presented.

Preservation and Conservation of Architectural Heritage of Pabna City[Full-Text ]
Audity Biswas

Heritage building conservation , adaptive re-use of buildings is often the only way that the historic aesthetic values can be saved economically and heritage buildings can be brought up to contemporary standards. Under the colonial discourses, rapid changes have been occurred in every aspects of socio-cultural and economical perspective in whole Bengal As a part of its continuation a large number of colonial buildings of are exits in Pabna city most of them are in a vulnerable condition. This study aim to a straight –forward practical solution and alternative approach that may be adopted for compliance with building archaeology of pabna city .This paper describes the historical site of Pabna in respect of planning tools- “preservation and Conservation’’ .Methodology is build up in respect of identification of Heritage Sites in detailed Area Plan description and review primary and secondary documents.

The Tidal Oscillations Under The Sea Levelrise Effects In Central Vietnam[Full-Text ]
Nguyen Quoc Trinh, Nguyen Minh Huan, Pham Van Tien, Nguyen Quang Vinh

Tide is one of the most important phenomena in the oceans. In all over the world as well as in Vietnam, the tide has been studied very early and such great achievements have been recorded.However, under the impact of climate changes and sea level rise, the local-to-regional-scalechanges will cause significant changes in the coastal system. This paper gives some results ofresearch on the tidal changes in the central region of Vietnam by using the hydrodynamic modeland data analysing model. The simulation results of the tide in the central coast of Vietnam showthat the tide can change both in the amplitude and phase distribution of the tidal constituents as M2,S2, K1 and O1. Specifically, the results of the average values of M2 are 0.1 m and 10.20; for S2 are0.12 m and 12.50; for K1 are 0.2 m and 17.20; for O1 are 0.21 m and 20.20. Some results of thisstudy showed that the most important contribution to the change of the tide in the region is thechange of topography and the submerged areas.

Capturing Semantics of Web Page using TAGs-Based Approach for Information Retrieval[Full-Text ]
R .Vishnu Priya

A web search engine has been developed and used for retrieving the relevant information. One of the critical issues of the engine is to provide relevant information to the user query. This is due to the ranking mechanism used by the conventional system is not effective. This demand has spurred to develop an approach that supports to improve the precision of retrieval. In this paper, the terms related to the TAGs of web pages are considered and weighted according to the characteristics. This ranking will retrieve the users‟ desired web pages in top-k results. From the experimental result, we have observed that the performance of the proposed approach is encouraging compared to the recent web search engine.
