We propose a predictive location based relaying for hybrid cellular and ad-hoc systems that can provide interference minimization to uplink transmission. In the case of dense netw...
Within the public sector, the deployment of enterprise architecture is often an attempt to address the decentralization/centralization relationships to improve the links between t...
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...
Abstract In this paper we present a real automatic meteorological information system that, not only provides friendly voice access to real-time data coming from automatic sensors, ...
Bitmap indexes are widely used in Decision Support Systems (DSSs) to improve query performance. In this paper, we evaluate the use of compressed inverted indexes with adapted quer...
