A ray-based method has been proposed as a neutral description method for various kinds of 3-D images. In this paper, we propose a new method for converting a set of range and color data of 3-D objects obtained by a range finder into ray data. This method enables us to handle range data in the same manner as other kinds of 3-D images and to use conventional image processing techniques to improve...

A pipeline is a linear array of processors with an input node at one end and an output node at the other end. This paper presents k-gracefully-degradable graphs which, given any set of up to k faults, contain a pipeline that uses all the healthy processor nodes. Our constructions are designed to tolerate faulty input and output nodes, but they can be adapted to provide solutions when the input ...

In complex event processing (CEP), load shedding is performed to maintain a given latency bound during overload situations when there limitation on resources. However, implies degradation in the quality of results (QoR). Therefore, it crucial perform way that has lowest impact QoR. Researchers, CEP domain, propose drop either events or partial matches (PMs) cases. They assign utilities PMs by c...
