The problem of handwritten recognition considered to be very important problem because of its numerous applications and theoretical values in the domain of pattern recognition.In this research, models of Neural Networks are used to recognize written characters, applying Artificial Neural Network (ANN) of three types, which are: - Kohenen All Classes in One Network (ACON), Kohenen  One Class in One Network(OCON), and Learning Vector Quantization (LVQ).The feature extraction process made use of Haar Wavelet Transformation to extract the parametric features of the

In the past few years, the world has witnessed a rush towards the use of clean renewable energy sources in order to reduce environmental pollution, energy cost, fuel consuming. Therefore, this work focused toward an important sector in renewable energy, which is wind energy, where the work was divided into four objectives namely;- Wind statistics: This  item  presents  a  statistical  analysis  of  the  wind resources at five selected sites (Ali Al-karbee, Baghdad, Basrah, Nasiriya, Kerbala) conducted on annual and monthly basis.

A quantum statistical mechanics model for the BEC phenomenon in fractal media is formulated. This model is based upon the generalized nonextensive Tsallis thermostatistics. The thermodynamic behavior this formulation (the temperature dependence of the condensate thermodynamic properties) is also investigated.
