Due to the advances in the Micro-electro-Mechanical systems (MEMS) and low power integrated circuits, digital electronics gave rise to the development of micro sensors (Sohrabi,2000)[12]. In the past few years there was a great research done by Kanchan Verma Dept. of Computer science and engineering, Punjab Institute of Technology (PTU main campus) Kapurthala, (INDIA) E-mail: kanchanverma252@gm...

A brief review is presented of the stability domain of threeand fourcharge ground-states when the constituent masses vary. Rigorous results are presented, based on the scaling behavior and the convexity properties deduced from the variational principle. They are supplemented by accurate numerical computations. Talk given at the Workshop Critical Stability, Les Houches, Oct. 8–12, 2001, to appea...

The deuteron-proton elastic scattering is studied in the multiple scattering expansion formalism. The contributions of the one-nucleon-exchange, singleand double scattering are taken into account. The Love and Franey parameterization of the nucleon-nucleon t-matrix is used, that gives an opportunity to include the off-energy-shell effects into calculations. Differential cross sections are consi...

This study mainly concentrates on metallurgical structure of the ferrous ancient crafts, specially the discovered ferrous man-made pieces in Ilam which are aged more than 3000 years. The pieces were discovered in Ize a town located in the south east of Ahvaz , in the southern of Iran. The crafts include an ferrous bar, a 3-side and a 4 side bayonets which were microscopically studied by Electro...
