Shared memory in a parallel computer provides prowith the valuable abstraction of a shared address space--through which any part of a computation can access any datum. Although un...
Many emerging application domains require database systems to support efficient access over highly multidimensional datasets. The current state-of-the-art technique to indexing hi...
Practitioners and researchers often refer to error rates or accuracy percentages of databases. The former is the number of cells in error divided by the total number of cells; the...
We study a routing problem in wireless sensor networks where sensors are duty-cycled. When sensors alternate between on and off modes, delay encountered in packet delivery due to ...
Recent text and speech processing applications such as speech mining raise new and more general problems related to the construction of language models. We present and describe in...
