Special persons are the part of every culture all over the words. There are different types of special persons (like blind, deaf, physically disabled and mentally distorted persons). This research work only contribution for special persons who are deaf. Communication is a way by which persons can

The College of Education at the University of Northern Iowa (UNI) established collaborative partnership agreements with nine major school districts in Iowa where UNI student teachers were placed. One collaborative project connected the campus coordinator with the nine off-campus sites through the campus computer network (Caucus). In the 1993-94 school year the transition to Internet is being made. This paper describes: (1) how the UNI computer network (Cauls) was developed and extended; (2) projects that caused practitioners to become active partners in the UNI Teacher Education program; (3) projects such as newsletters, establishment of mentor programs for student teachers, and the organization of seminars and local educational programs that were organized through the network; (4) practitioner's use of the network to serve on University committees, to help plan conferences in

This thesis investigates the idea of using phoneme recognition as a telephone communication aid aimed at heating-impaired people. A laboratory ASR system has been developed with which on-line trials (user studies) have been conducted in order to investigate and evaluate the idea of using state

We introduce a system for sensing complex social systems with data collected from one hundred mobile phones over the course of six months. We demonstrate the ability to use standard Bluetooth-enabled mobile telephones to measure information access and use in different contexts, recognize social

A summary table displays the results of the data analysis for each of the libraries and each of the categories: (1) availability of core collections; (2) specific requests; (3) reference queries; (4) special telephone lines; (5) advertisement of services; (6) a librarian

The Internet presents numerous sources of useful information---telephone directories, product catalogs, stock quotes, weather forecasts, etc. Recently, many systems have been built that automatically gather and manipulate such information on a user's behalf. However, these resources

Although useful in practice there are still circumstances where it is not ideal. For instance, if the called

of designing signal processing and communications systems, ranging from algorithms and communication strategies, simulation, hardware and software design, parallel computing, and generating real-time prototypes. To accommodate this breadth, Ptolemy must support a plethora of widely-differing design styles

suggests ways to solve these currently open problems. It also discusses how the theories of communication and computation are beginning to provide the tools to solve cryptographic problems of long standing.
