Recent work on the problem of detecting synonymy through corpus analysis has used the Test of English as a Foreign Language (TOEFL) as a benchmark. However , this test involves as few as 80 questions , prompting questions regarding the statistical significance of reported results. We overcome this limitation by generating a TOEFL-like test using WordNet,(More)

Advances in communication and processing have made ad-hoc networks of wireless devices a reality. One application is home entertainment systems where multiple Home-to-Home (H20) devices collaborate as peers to stream audio and video clips to a household. In this study, we investigate the feasibility of IEEE 802.11a protocol in combination with both TCP and(More)
— In an ad-hoc network of mobile devices, a device is termed a zebroid when it carries a data item residing on a server-device to a client-device referencing that item. The system employs a zebroid when its travel path intersects that of the server and the client and this information is known in advance. The motivation for use of a zebroid is to minimize(More)
We present a fast yet highly effective stochastic algorithm, Simmered Greedy Optimization (SG(N)) for solving the co-clustering problem: to simultaneously cluster two finite sets by maximizing the mutual information between the clusterings. (Clustering one set by this criterion is a special case.) This is a combinatorial optimization problem of great(More)
