AbstractDue to aspect-oriented mechanisms explosion, their concepts arrive to distributed systems tackling concepts as security, persistence, or synchronization, especially in middleware approaches. Regarding distributed databases, the research has been focused mainly on object-oriented databases. Based on the great impact of…

The concept of “approximate” searching has applications in a vast number of fields. Some examples are non-traditional databases (e. g. storing images, fingerprints or audio clips, where the concept of exact search is of no use and we search instead…

EQUIVALENCE OF SOME STRINGS. THESE ARE LOWERCASE VERUS UPPERCASE MATCHING, MORPHOLOGICAL INFLECTION, DERIVATION, AND SYNONYMY OF WORDS: E.G. GIVE A QUERY COMPUTER, FIND COMPUTER COMPUTING, WORKSTATION. THE LATTER PROBLEMS ARE VERY IMPORTANT IN LANGUAGES WITH RICHER MORPHOLOGY AND LESS STABLE…

Este artículo presenta un detector de aristas y esquinas, implementado en el dominio del proyecto GEIST (un Sistema de Información Turística Asistido por Computador) para extraer la información de aristas rectas y sus intersecciones (esquinas en la imagen) a partir…

THE GOAL OF THIS PAPER IS TO DOCUMENT THE USE OF TIME SERIES IN COLOR MATCHING. ALTHOUGH TIME SERIES ARE NOT COMMONLY USED FOR THIS PURPOSE, THE RESULTS OBTAINED, BASED ON THE PRINCIPLE OF SIMILARITY IN TIME SERIES USING THE…

Software engineering has entered a new era, the Internet and its associated technologies require a different conceptual framework for building and understanding software solutions.
Users ask to develop applications more rapidly, and software engineers need to ensamble systems from preexisting…

A Federated System is a collection of independent, cooperative, possibly heterogeneous and autonomous computer systems (usually database systems) which allows sharing all or some of its data. A Service-oriented Architecture is an application architecture whose functionalities are defined as independent…

SE REALIZÓ UN ANÁLISIS TEMPORAL Y ESPACIAL DE LA TEMPERATURA DEL AIRE EN EL DOSEL URBANO DE LA CIUDAD DE MEXICALI, B. C. Y ALREDEDORES RURALES. A UNA BASE DE DATOS DE LARGO PERÍODO (1950-2000) SE APLICARON VARIAS PRUEBAS ESTADÍSTICAS…

Nowadays, data intensive applications are in constant demand and there is need of computing environments with better intelligent capabilities than those present in today's Database Management Systems (DBMS). To build such systems we need formalisms that can perform complicate inferences,…

This paper presents a data structure based on Sparse Spatial Selection (SSS) for similarity searching. An algorithm that tries periodically to adjust pivots to the use of database index is presented. This index is dynamic. In this way, it is…
