The rise of ad-hoc data-intensive computing has led to the development of data-parallel programming systems such as Map/Reduce and Hadoop, which achieve scalability by tightly cou...
In this paper, we focus on tradeoffs between storage cost and rekeying cost for secure multicast. Specifically, we present a family of algorithms that provide a tradeoff betwee...
Advancement in wireless infrastructure for data access through third generation wireless and wi-fi technologies makes it possible to use mobile devices for various activities and ...
This paper presents two algorithms for maintaining Btree index consistency in a DBMS which does not use write-ahead logging (WAL). One algorithm is similar to shadow paging, but i...
A system for the acquisition, storage, indexing, and retrieval of map images is presented. The input to this system are raster images of separate map layers and map composites. A ...
