Contemporary commercial databases are placing an increased emphasis on analytic capabilities. Data mining technology has become crucial in enabling the analysis of large volumes of data. Modern data mining techniques have been shown to have high accuracy ...

The exponential growth in the volume of publications in the biomedical domain has made it impossible for an individual to keep pace with the advances. Even though evidence-based medicine has gained wide acceptance, the physicians are unable to access ...

Martin Marietta Data Systems is designing and implementing for Martin Marietta Orlando Aerospace, a major defense contractor, a system to computerize and integrate all unclassified CAD/CAM graphic outputs related to a large defense project. The system ...

Normalization of relations to third normal form is often a difficult concept for students to grasp and working through examples helps. This tool is a simple tutorial implemented in JavaScript which takes the student through the multi-step process of ...

Manchego sheep breeding represents an important factor in the economy in the region of Castilla-La Mancha, Spain. For this reason, the selection scheme for Manchego sheep (ESROM) was created to improve milk production in ewes belonging to the Manchego ...

This work discusses the problem of generating association rules from a set of transactions in a relational database, taking performance and accuracy of found results as the essential aspects for comparing association mining algorithms. We do a critical ...

Query optimization for relational database systems is a combinatorial optimization problem, which makes exhaustive search unacceptable as the query size grows. Randomized algorithms, such as Simulated Annealing (SA) and Iterative Improvement (II), are ...

Continuous K nearest neighbor queries (C-KNN) are defined as finding the nearest points of interest along an enitre path (e.g., finding the three nearest gas stations to a moving car on any point of a pre-specified path). The result of this type of query ...

This paper presented a new kind of query, global nearest neighbors query, which is based on a special distance, global distance, between two objects during given time interval. According to the relationship with continuous nearest neighbor query, a native ...

In the last years, the main orientation of formal concept analysis (FCA) has turned from mathematics towards computer science. This article provides a review of this new orientation and analyses why and how FCA and computer science attracted each other. ...

This paper presents the architecture, the system implementation and the performance evaluation of an innovative Internet-based service for object position tracing and tracking (T&T). It supports "full" T&T, as tracking data are not limited only to warehouse ...

In this paper, a new probe-based distributed deadlock detection algorithm is proposed. It is an enhanced version of the algorithm originally proposed by Chandy's et al. [5,6]. The new algorithm has proven to be error free and suffers very little performance ...

The uncertainty management problem for moving objects databases has been well studied recently, with many models and algorithms proposed. However, very limited work has dealt with the index of uncertain trajectories for a running moving objects database. ...
