We present a method for performing linear regression on the union of distributed databases that does not entail constructing an integrated database, and therefore preserves confidentiality of the individual databases. The method can be used by statistical agencies to share information from their individual databases, or to make such information available to others.

Aggregate functions are particularly useful when dealing with extremely large volumes of data. In business and statistical databases, aggregate queries have been leveraged by powerful methods such as On-Line Analytical Processing (OLAP). In contrast, current technology for raster image databases is lagging behind. A comparative study between raster image and business databases has shown similar...

An accurate statistical energy function that is suitable for the prediction of protein structures of all classes should be independent of the structural database used for energy extraction. Here, two high-resolution, low-sequence-identity structural databases of 333 alpha-proteins and 271 beta-proteins were built for examining the database dependence of three all-atom statistical energy functio...

The recent enormous increase in the use of networked information access and on-line databases has led to more databases being available in languages other than English. The Centerfor Intelligent Information Retrieval (CIIR) at the University of Massachusetts is involved in a variety of industrial, government, and digital library applications which have a needfor multilingual text retrieval. Mos...

The global investigation of disasters in recent years shows that their number has increased annually and the number of affected people and costs of disasters are increasing
