Human“computer interaction (HCI) is the study of interaction between people (users) and computers. It is often regarded as the intersection of computer science, behavioral sciences, design and several other fields of study. Interaction between users and computers occurs at the user interface (or simply interface), which includes both software and hardware, for example, general-purpose computer peripherals and large-scale mechanical systems, such as aircraft and power plants. The Association for Computing Machinery defines human-computer i ....etc

This paper is an overview of the sources and nature of various transient over voltages and the problems that may result in a low voltage ac distribution system. Voltage transients may be repeatable transients or random impulses and they have got remarkable effects on semiconductors, electrochemical contacts, insulation etc. Switching parallel loads on the same branch of distribution system as well as lighting are responsible for these transient overvoltages. Low voltage ac mains system should be protected from these transient overvoltages. For ....etc

ABSTRACT
The Human-Computer Interface is a multidisciplinary field concerned with the design and evaluation of interacting computer systems from the user perspective. It deals with the way that computers and their users communicate. It pertains to the performance of tasks by humans and machines, the structure of human-machine communication, the engineering aspects of designing, building and specifying interfaces so that computers are easy to use and do what people want them to do. HCI requires the understanding of the capabi ....etc

Definition
Local Multipoint Distribution Service (LMDS), or Local Multipoint Communication Systems (LMCS), as the technology is known in Canada, is a broadband wireless point-to-multipoint communication system operating above 20 GHz that can be used to provide digital two-way voice, data, Internet, and video services. The term Local indicates that the signals range limit. Multipoint indicates a broadcast signal from the subscribers; the term distribution defines the wide range of data that can be transmitted, data ranging anywhere from v ....etc

Abstract:
Through an examination of the emerging domain of cognitive systems, with a focus on attention-centric cognitive systems used for notification, this document explores the human-computer interaction challenges that must be addressed for successful interface design. This document asserts that with compatible tools and methods, user notification requirements and interface usability can be abstracted, expressed, and compared with critical parameter ratings; that is, even novice designers can assess attention cost factors to deter ....etc

With the increasing loads, voltages and short-circuit duty of distribution substation feeders, distribution over current protection has become more important today than it was even 10 years ago.

The ability of the protective equipment to minimize damage when failures do occur and also to minimize service interruption time is demanded not only for economic reasons but also because the general public just expects ?reliable? service. This publication will attempt to review some of the present distribution practices, particularly with regard to ....etc

Electric power utilities throughout the world are undergoing considerable change in structure, operation, and regulation. One of the major effects of this change is increased importance of distribution automation. With improved Distribution Automation (DA), both the reliability and the efficiency of electric power distribution can be increased. Communication system is essential to performance of automated distribution systems. It is necessary to perform reliability assessments of communication facilities in carrying out the control functions. T ....etc
