للكاتبين : Hassan Shaheen and Amir Atiya Department of Computer Engineering Faculty of Engineering, Cairo University , Giza , EGYPT ABSTRACT This work deals with the problem of forecasting a complex environment behavior. The word “complex behavior” is here used in the sense that the environment may be modeled as an almost random walk environment. Stock market prediction is known …

للكاتبين : El-Desouky N., Ghali N., Zaki M. Faculty of Science (for girls)- Al-Azhar University- Cairo – Egypt ABSTRACT In this paper we propose a new approach to weight variation in Particle Swarm Optimization (PSO) called Exponential Particle Swarm Optimization (EPSO). EPSO depends on exponential variation for the inertia weight; which under all testing cases makes the particle swarm converges …

للكاتب : A.M. KOHAIL Mech Eng., Prod. Dept.(R), MTC , Cairo ABSTRACT Laser drilling has been widely used in industry. The laser drilling process occurs when the laser beam is focused with enough intensity to melt and vaporize the drilled substrate. The high throughput energy rate is one of the most important laser drilling advantages. Most of laser material processing …
