in many computer vision applications, segmenting and extraction of moving objects in video sequences is an essential task. background subtraction, by which each input image is subtracted from the reference image, has often been used for this purpose. in this paper, we offer a novel background-subtraction technique for real-time dynamic background generation using color images that are taken fro...

To avoid undesirable disconnection of healthy wind generators (WGs) or a wind power plant, a WG protection relay should discriminate among faults, so that it can operate instantaneously for WG, connected feeder or connection bus faults, it can operate after a delay for inter-tie or grid faults, and it can avoid operating for parallel WG or adjacent feeder faults. A WG protection relay based on ...

Zero-sequence currents in high-voltage power systems during normal operation can have a significant influence on nearby infrastructure. It is therefore necessary to gain insight into typical levels of zero-sequence variety operational situations. Measurements provide this insight. When performing measurements, one needs know the uncertainty associated with measurement draw accurate conclusions....

In this paper, we describe a generative process planning system for robotic sheet metal bending press-brakes. This process planning system employs a distributed planning architecture. Currently, our system consists of a central operation planner and three specialized domain speci c planners: tooling, grasping, and moving. The central operation planner proposes various alternative partial sequen...

In any CAPP system, selection of machining operation sequence is one of the most important activities for manufacturing a part as per the technical specification and part drawing. Any fixed sequence of the operations that is generated in a process plan cannot be the best possible sequence for all the production periods or for the criteria such as quality and machine utilization. Thus an aim sho...

A database specification consists of static and temporal constraints and a set of database operation descriptions. A database iS viewed as a dynamic object and a sequence of database states constitutes an evolution of the database. A formal method for verifying database specifications is proposed. The method checks if the static constraints are consistent, analyses the database operation descri...

Data mining techniques can be used for discovering interesting patterns in complicated manufacturing processes. These patterns are used to improve manufacturing quality. Classical representations of quality data mining problems usually refer to the operations settings and not to their sequence. This paper examines the effect of the operation sequence on the quality of the product using data min...
