The study of discriminative stimulus control of responding maintained by positive reinforcement has a long-standing and dominant role in the behavioral literature. In contrast, the literature on discriminative stimulus control of response suppression by punishment is small and moribund. Investigating…

The proper orthogonal decomposition (POD) is shown to be an efficient model reduction technique for simulating physical processes governed by partial differential equations. In this paper, a POD reduced model of a barotropic ocean circulation for coastal region domains was…

Se investigó el efecto de la absorción móltiple de fotones en la ionización, MPI, y disociación, MPD, del Naftaleno. Para ello se utilizó radiación láser de 266 nm con anchos de pulso de 4.5 ns, e intensidades del orden de…

Two main research areas in Pattern Recognition are pattern classification and pattern restoration. In the literature, many models have been developed to solve many of the problems related to these areas. Among these models, Associative Memories (AMs) can be highlighted.…

In some industries such as logistics services, bank services, and others, the use of automated systems that deliver critical business information anytime and anywhere play an important role in the decision making process. This paper introduces a “Generic model to…

IN THIS DISSERTATION THE GEONTOMET METHODOLOGY IS PRESENTED. IT IS ORIENTED TO FORMALIZE THE GEOGRAPHIC DOMAIN CONCEPTUALIZATION ACCORDING TO THE SPECIFICATIONS OF THE INSTITUTO NACIONAL DE ESTADÍSTICA, GEOGRAFÍA E INFORMÁTICA (INEGI). THE MAIN GOAL IS TO PROVIDE SEMANTIC DESCRIPTIONS, WHICH…

THIS PAPER PROPOSES A NOVEL AND PRACTICAL MODEL-BASED LEARNING APPROACH WITH ITERATIVE REFINEMENT FOR SOLVING CONTINUOUS (AND HYBRID) MARKOV DECISION PROCESSES. INITIALLY, AN APPROXIMATE MODEL IS LEARNED USING CONVENTIONAL SAMPLING METHODS AND SOLVED TO OBTAIN A POLICY. ITERATIVELY, THE APPROXIMATE…

Para conocer el valor que los caracteres estructurales tienen para la reconstrucción filogenética de la subtribu Oncidiinae se realizó un análisis de parsimonia combinado con base en datos anatómico foliares, morfológicos y secuencias de ADN de las regiones matK e…

Analysis of the general rainfall trend is vital in understanding the underlying features, for the purpose of forecasting and in identifying the changes and impacts that are very crucial for an agro-based economy like the one of India. Situated on…

Se realizaron mediciones de metales e iones inorgánicos presentes en muestras de PM10 colectadas en cinco sitios distribuidos en las ciudades de San José, Heredia y Belén. Las muestras fueron colectadas con muestreadores de alto volumen marca Thermo Andersen sobre…
