Dynamic excitation of any machine tool structure is based on natural frequency of the structure and corresponding mode shape. Initial work of the thesis presents a systematic procedure and details of the use of experimental analysis and finite element modal analysis technique for determining the structural dynamic response of end milling machine.The simplified experimental modal analysis of dif...

1. (10 pts) The term migratory insertion is often used to describe the general process of a neutral metal bound ligand reacting with a cisoidal anionic ligand to produce a new coupled anionic ligand. For example, the reaction of 3a,b(mono) to produce 4a,b. There are separate, more specific descriptions for this general process called migration and insertion. An insertion specifically refers to ...

Dear Editor, It was with great sadness that we learnt of the death of Prof Barrie Jones on 19 August 2009 in Tauranga, New Zealand, aged 88. He was admired worldwide for his work in developing the concept of prevention of blindness and for establishing the International Centre for Eye Health (publishers of the Community Eye Health Journal) in 1981. He was in fact responsible for encouraging the...

of Prof. Yau's lecture, Monday, April 2 [with additional references and remarks] (for people who missed the lecture) A geometric structure on a manifold is a cover by coordinate systems [a " sub-atlas " ] in which the transition functions from one coordinate system to another are not arbitrary mappings but rather belong to some specific set of mappings from (open subsets of) Euclidean space to ...

propose: the stratification of iranian knowledge and information science academic member in viewpoint of presence and effectiveness and scientific and professional performance are the main aims of this article. methodology: in this applied research, descriptive survey and webometrics methods were implemented. the research population included the iranian knowledge and information science academi...

Almost all of his students were older than him! Through intellect and hard work, he made rapid academic progress, and was appointed as Professor of Psychology in 1988. While at Birkbeck, he was appointed the Ronald Tress Prize for advancements in his field, the first of many such awards. During his time in Birkbeck an equally important step in his life was made by meeting his wife Jane. Both of...

My research is primarily concerned with problems related to the theoretical aspects of the analysis and design of algorithms. Although I have studied many classical problems including those that can be found in standard textbook in algorithms (for example, string matching [16, 25, 34, 35], k-connectivity problems in graphs [9, 18, 20], and the problem of finding an optimum order of multiplying ...
