A major concern of researchers who seek to improve human-computer communication involves how to move beyond literal interpretations of queries to a level of responsiveness that takes the user's misconceptions, expectations, desires, and interests into consideration. At Maryland, we are investigating how to better meet a user's needs within the framework of the cooperative answering system of Ga...

To reuse one or several existing systems in order to develop a complex system is a common practice in software engineering. This approach can be justified by the fact that it is often difficult for a single Information System (IS) to accomplish all the requested tasks. So, one solution is to combine many different ISs and make them collaborate in order to realize these tasks. We previously prop...

IEEE 802.15.4 is a global standard designed for the low power consumption, low cost, and low data rate. Thus, this standard is advantageous to implement ubiquitous sensor network (USN). However, researchers do not have been studied to employ cooperative communication in this system. Cooperative relaying system has been shown to help the destination to get the spatial diversity. It is possible t...

Cooperative communications are gaining much interest in modern communications because they allow to improve the information transmission between a source and a destination using various intermediate terminals. This project is a complete study of cooperative systems, analyzing its performance and comparing the use of a single terminal with the use of the Alamouti code, which uses two terminals. ...
