An emergency communication system (ECS) is any system (typically, computer-based) that is organized for the primary purpose of supporting one-way and two-way communication of emergency messages between both individuals and groups of individuals. These systems are commonly designed to integrate the cross-communication of messages between a variety of communication technologies, forming a unified communication system intended to optimize communications during emergencies. ....etc

ABSTRACT

The demand for high-capacity wireless services is bringing increasing challenges, especially for delivery of the last mile . Terrestrially, the need for line-of-sight propagation paths represents a constraint unless very large numbers of base-station masts are deployed, while satellite systems have capacity limitations. An emerging solution is offered by high-altitude platforms (HAPs) operating in the stratosphere at altitudes of up to 22 km ....etc

ALTERNATIVE COMMUNICATION SYSTEMS DURING DISASTERS

PSTN or the public switched telephone network is the prime network responsible for transmitting and receiving voice, fax and data. All government and private offices, police stations, fire stations, hospitals and majority of homes and business places are serviced by the PSTN line.

. Amateur Radio operation does not use ground based infrastructure. Moreover these have limited power needs which can easily be met by batteries and generations. Therefore, it has been experienced that Amateur R ....etc

This seminar presents the manufacturing processes of thermoplastic structures including piezoceramic patches (PZT). The objective of the study reported here was to find a trade-off between the manufacturing conditions and the thermal endurance of the PZT patches. We studied the influence of high temperatures on the PZT efficiency during manufacturing. Two processes were considered: injection molding and thermoforming. The studied object consists of a polypropylene plate containing a PZT patch integrated at different positions. On the one hand, ....etc

Ham Radio is also know as Amateur radio.It is a community of people that use radio transmitters and receivers to communicate with other Amateur radio operators. If you were to ask a dozen different amateurs what ham radio meant to them chances are you would get 12 different answers. Amateur radio operators are often called ham radio operators or simply hams and frequently the public is more familiar with this term than with the legal term Radio Amateur. The source of this nickname is for all practical purposes lost from the beginning.

ABSTRACT

This paper describes in detail, field experiments performed on a single-phase, distribution transformer to study the behavior of transformer terminal parameters during internal winding faults. A custom-built transformer provided with external taps was used for these tests. The taps were used to stage various internal winding faults in the transformer. Terminal values of voltages and currents were monitored and the results presented. A comparison of these results with simulation results is also presented
