We propose a new compression algorithm that is tailored to database applications It can be applied to a collection of records and is especially e ective for records with many low to medium cardinality elds and numeric elds In addition this new technique sup ports very fast decompression Promising application domains include decision sup port systems DSS since fact tables which are by far the la...

Search engines are an essential tool for modern life. We use them to discover new information on diverse topics and to locate a wide range of resources. The search process in all practical search engines is supported by an inverted index structure that stores all search terms and their locations within the searchable document collection. Inverted indexes are highly optimised, and significant wo...

The speciication and derivation of substitution for the de Bruijn representation of-terms is used to illustrate programming with a function-sequence monad. The resulting program is improved by interactive program transformation methods into an eecient implementation that uses primitive machine arithmetic. These transformations illustrate new techniques that assist the discovery of the arithmeti...

The article describes a new data structure called neuro-index. It is an alternative to wellknown file indexes. The neuro-index is fundamentally different because it stores weight coefficients in neural network. It is not a reference type like ”keyword–position in a file”.

In the relevant literature, there has been a lack of discussion to focus particularly on the relationship between entrepreneurship and international trade. It is more restricted when one intends to seek an interaction between international trade and the indexes of the 3A approach of entrepreneurship, including entrepreneurial attitude, activities and aspirations which are collected from Global ...

One of the fundamental tasks that data warehouse (DW) administrator needs to perform during the physical design is to select the right indexes to speed up her/his queries. Two categories of indexes are available and supported by the main DBMS vendors: (i) indexes defined on a single table and (ii) indexes defined on multiple tables such as join indexes, bitmap join indexes, etc. Selecting relev...

Dua and Miller (1996) created leading and coincident employment indexes for the state of Connecticut, following Moore’s (1981) work at the national level. The performance of the DuaMiller indexes following the recession of the early 1990s fell short of expectations. This paper performs two tasks. First, it describes the process of revising the Connecticut Coincident and Leading Employment Index...

A CARDINAL GOAL of librarians of institutions of higher learning is to build up collections of permanent value. For a non-fiction work to serve this purpose, we would expect it to be read in whole or in part and to be referred to for such things as facts, opinions, ideas, or felicitous phrasing. College librarians have to buy books selectively, a task made more difficult by the rising cost of b...
