Ubiquitous computing which is providing various convenient services to user will prevail in future. To realize ubiquitous service, analyzing technical and information factors for service implementation is necessary. This paper defines ubiquitous service model to satisfy user demands and we analyze technical and information factors in order to realize services. Based on the factors, we extracts and classifies common compositions of ubiquitous services to suggest guidelines of service design.

Optimal generation dispatch algorithm is developed using L.P and load dispatch method. The algorithm is composed with three steps. Fist phase, analytical algorithm is adopted to solve to minimize quadratic cost functions which fits well for planning purpose. Second phase uses L.P method for obtain economic redispatch that satisfies line constraints. When there is no solution whitch satisfy line constraints load shedding algorithm solves the problem.

The global least squares method (Gl-LSQR) is a generalization of LSQR method for solving linear system with multiple right hand sides. In this paper, we present how to apply this algorithm for solving the image restoration problem and illustrate the usefulness and effectiveness of this method from numerical experiments.
