the control problem and dynamic programming is a powerful tool in economics and management. we review the dynamic programming problem from its beginning up to its present stages. a problem which was involved in physics and mathematics in i 7” century led to a branch of mathematics called calculus of variation which was used in economic, and management at the end of the first quarter of the 20” ...

One of the most important technical problems in optical WDM network is the dynamic routing and wavelength assignment (dynamic RWA) problem, which is to set up lightpaths and assign wavelengths dynamically in order to establish a channel between optical source and destination nodes. Previous studies have solved many variations of the dynamic RWA problem under the assumption of ideal conditions r...

This paper presents a new modeling of elevator group intelligent scheduling system with destination floor guidance. The traditional input mode of separate hall call registration and the destination selection is improved to a single-input mode. On this basis, dynamic partition method in up-peak traffic is studied. This method means dynamically adjust division of floor region based on flow rate a...

At present, the video background extraction algorithm of static scene has been nearly mature. However, video background extraction in dynamic scenes remains a challenge. In order to solve this problem, this paper proposes a dynamic scenes video background extraction algorithm. Here, our dynamic scene is based on camera movement. Firstly, we detect saliency target of video frame according to con...

Orthonormal subspace analysis (OSA) is proposed for handling the decomposition issue and principal component selection in traditional key performance indicator (KPI)-related process monitoring methods such as partial least squares (PLS) canonical correlation (CCA). However, it not appropriate to apply static OSA algorithm a dynamic since pays no attention auto-correlation relationships variable...

The well-founded model provides a natural and robust semantics for logic programs with negative literals in the bodies of rules. Although various procedural semantics have been proposed for query evaluation under the well-founded semantics, the practical issues of implementation for eeective and eecient computation of queries have been rarely discussed. This paper investigates two major impleme...
