Two recent, moderate earthquakes (March 27, 1996, =5.4; January 21, 1997, =5.4), which occurred close to the town of Pinotepa Nacional, Oaxaca, Mexico, were recorded at the near-source VBB station of PNIG and by several other stations of the Mexican…

Mean flow and stratification data obtained from an eight-layer quasigeostrophic model of the California Current System are used to feed a linearized model, from which a stability problem is solved. Frequencies, phase speeds, group velocities, growth rates and vertical structures…

, El lenguaje es una de las áreas que se ven influidas debido al contacto cultural. Este artículo trata sobre la convivencia del porhé con el español desde sus primeros contactos y la influencia mutua de las dos lenguas, basándose…

DATA INTEGRATION IS A PROCESS OF RETRIEVING, MERGING AND STORING OF DATA ORIGINATED IN HETEROGENEOUS SOURCES OF DATA. THE MAIN PROBLEM FACING THE DATA INTEGRATION IS THE STRUCTURAL AND SEMANTIC HETEROGENEITY OF PARTICIPATING DATA. A CONCERN OF RESEARCH COMMUNITIES IN…

Half-hourly estimates of solar radiation were obtained from satellite data for the Yaqui Valley in Sonora, Mexico for the period November 1998 to March 1999. Estimates were made on a 50 km grid using the Global Energy and Water-Cycle Experiment…

, LOS DATOS SUPONEN UNA PARTE FUNDAMENTAL DE LOS SISTEMAS DE INFORMACIÓN. CONSEGUIR CONTROLAR LA COMPLEJIDAD APORTADA POR ELLOS RESULTA, POR TANTO, IMPRESCINDIBLE. UNA FORMA DE REALIZAR ESTE CONTROL ES MEDIANTE LA UTILIZACIÓN DE MÉTRICAS ESPECÍFICAS PARA BASES DE DATOS,…

EN ESTE TRABAJO PRESENTAMOS UNA NUEVA FORMALIZACIÓN DEL CONCEPTO DE OBJETO SIMBÓLICO DE MODO TAL QUE CONSTITUYE UNA BASE SOLIDA PARA UNA TEORÍA DE OBJETOS SIMBÓLICOS, LA QUE CONTENDRÁ COMO CASO PARTICULAR LA TEORÍA DE ANÁLISIS SIMBÓLICO DE DATOS DE…

Geothermal Inflow Performance Relationships (GIPR) may be used to estimate formation permeability, by overlapping the well inflow curve with different theoretical GIPR curves. This method does not require field measurement of the well inflow curve. The complete well inflow curve…
