Towards a comprehensive treatment

Heart failure constitutes an increasing health hazard with major demands on health care resources. Recent major advances in drug treatment have yet to be translated into increased survival of heart failure patients in the community at large. Failure of diagnosis is a major factor in delaying early and adequate treatment. Echocardiography probably provides the most reliable and inexpensive instr...

Ccef to Extend Network Lifetime in Wsns

The pervasive application of wireless sensor networks (WNSs) is challenged by the scarce energy constraints of sensor nodes. En-route filtering schemes, especially commutative cipher based en-route filtering (CCEF) can saves energy with better filtering capacity. However, this approach suffer from fixed paths and inefficient underlying routing designed for ad-hoc networks. Moreover, with decrea...

Towards Semantic City Models

3D city modeling is a very demanding task. It suffers from the same problems as general bottom-up 3D acquisition processes. Whatever the 3D acquisition system, there are always objects and surfaces that yield meager performance. Often the problems are fundamental and cannot be resolved through more sophisticated bottom-up processing. If however, one knows what kind of objects are to be modeled ...

Towards Comprehensive Web Search

Towards Comprehensive Web Search by Erik Warren Selberg Chair of Supervisory Committee Associate Professor Oren Etzioni Department of Computer Science & Engineering The World Wide Web has rapidly become a key medium for information dissemination to all members of society. However, its disorganized nature and sheer size can make it difficult for people to find information. Web search services ha...
