The current work presents an algorithm for recognition of partially occliided shapes in a cluttered scene The images are represented by a sequence of angles subtended at the corner points. The cost due to comparison between the input cluttered scene and the stored images is obtained from a cost function designed to storo the obtained information in the form of a cost matrix which is presented to the input of an optimization network. The parameters of the optimization network are determined so as, to minimize an energy function, the minima of which occur at the solutions of the problem. The results, as obtained in different domains (2D shapes and projected 3D shapes) with different degrees of occlusion, provide intereSting insights into the operation of the algorithm as well as avenues for future research.
Consumers are increasingly sending e-messages, purchasing products, managing finances, and locating information on-line by accessing the World Wide Web via the Internet. The demand for e-services and the installation of telecommunications and Internet equipment is occurring at a very rapid pace resulting in the construction of many Internet data center (IDC) facilities. The productivity and profits of IDCs, Internet Service Providers, and e-businesses solely depend upon providing power through an appropriately-size utility service feeder(s) for the operation of missioncritical equipment 7 days a week, 24 hours a day (i.e., 24 x 7), no exceptions. This growth has caused concerns among utilities regarding capacity planning requirements of IDCs. Additionally, the reliability of utility power-99.9 % (39's)-is also a concern when IDCs try to meet the power reliability and availability requirements of 99.9999 % (69's) and higher that IDCs are contracted to provide to e-businesses who lease IDC space. Through a better understanding of the power requirements and loads in IDCs, this paper addresses the capacity planning issues associated with IDCs and how distribution generation and alternative energy-storage technologies may be applied to provide high-availability power. Collaborative power quality research and testing being conducted by EPRI and EPRI PEAC to identify solutions to these problems is also discussed
