Flow visualization techniques using tracer markers such as die, smoke, hydrogen bubbles, etc., have been widely used in experimental investigations of large scale structures of a variety of flow fields. They have played an important role in understanding the physics of the coherent structures formation and evolution in the transitional as well as the turbulent regions of the flow fields. Howeve...
Drawing of square section rod from round bar can be done with two die shapes. In the first die shape, deformation starts from corners of the square and in second die shape, deformation starts from sides of square. This article has compared the drawing force for both die shapes and as a result optimum die shape was determined. Due to complexity of metal flow inside the die, analyzing of actual p...
Abstract The Nuclear dossier has been a hot topic since 1945 and after more than 80 years it is far from being closed.

After 20 years of research the first natural language AI Systems are beginning to enter the commercial market. Although computational models for many of the linguistic, communicative and cognitive abilities underlying intelligent language behavior are still open issues for basic research, an engineering discipline for natural language interfaces is emerging. The paper surveys the state-ofthe-ar...
