  • Mixing driven by radiative and evaporative cooling at the stratocumulus top 

    de Lozar, Alberto; Mellado González, Juan Pedro (2015-12-01)
    Article
    Open Access
    The stratocumulus-top mixing process is investigated using direct numerical simulations of a shear-free cloud-top mixing layer driven by evaporative and radiative cooling. An extension of previous linear formulations ...
  • Analysis and prediction of COVID-19 for EU-EFTA-UK and other countries 

    Català Sabaté, Martí; Cardona Iglesias, Pere Joan; Prats Soler, Clara; Alonso Muñoz, Sergio; Álvarez Lacalle, Enrique; Marchena Angos, Miquel; Conesa, David; López Codina, Daniel (2020-05-29)
    External research report
    Open Access
    The present report aims to provide a comprehensive picture of the pandemic situation of COVID-19 in the EU countries, and to be able to foresee the situation in the next coming days. We employ an empirical model, verified ...
  • Experimentally well-constrained masses of 27P and 27S: implications for studies of explosive binary systems 

    Sun, Lijie; Xu, Xinxing; Hou, S.Q.; José Pont, Jordi (Elsevier, 2020-03-10)
    Article
    Open Access
    The mass of 27P is expected to impact the X-ray burst (XRB) model predictions of burst light curves and the composition of the burst ashes, but large uncertainties and inconsistencies still exist in the reported 27P masses. ...
  • Learning by Back-Propagation: a systolic algorithm and its transputer implementation 

    Millan Ruiz, José del Rocio; Bofill, Pau (1989)
    External research report
    Open Access
    In this paper we present a systolic algorithm for back-propagation, a supervised, iterative, gradient-descent, connectionist learning rule. The algorithm works on feedforward networks where connections can skip layers and ...
  • Restriccions d'integritat en bases de dades deductives 

    Costal Costa, Dolors (1988)
    External research report
    Open Access
    This work describes the theory and implementation of a general theorem-proving technique for checking integrity of deductive databases called "Consistency Method", and presents examples in order to study the aplicability, ...
  • Viabilidad de protección sísmica de edificios con disipadores de energía histerética 

    Domínguez Santos, David; López Almansa, Francisco (Asociación Chilena de Sismología e Ingeniería Antisísmica, 2019)
    Conference report
    Open Access
    Este documento explora la viabilidad del uso de disipadores de energía en edificaciones de baja y mediana altura ubicados en zonas sísmicas. Este estudio podrá ser aplicado en edificaciones nuevas y existentes. Para ello, ...
  • Logarithmic advice classes 

    Balcázar Navarro, José Luis; Schöning, Uwe (1988)
    External research report
    Open Access
    Karp and Lipton [9] introduced the notion of non-uniform complexity classes where a certain amount of "side information", the advice, is given for free. The advice only depends on the length of the input. Karp and Lipton ...
  • Calibración con cálculos dinámicos no lineales del método de Newmark para análisis de estabilidad sísmica de laderas 

    Dong, Shan; López Almansa, Francisco; Ledesma Villalba, Alberto (Asociación Chilena de Sismología e Ingeniería Antisísmica, 2019)
    Conference report
    Open Access
    El método de Newmark es un procedimiento simplificado para analizar la estabilidad de laderas sometidas a acciones sísmicas. En esta formulación se considera un bloque infinitamente rígido situado sobre una superficie ...
  • Identificación no lineal de movimientos sísmicos en el lecho rocoso ingenieril a partir de registros tomados en la superficie 

    Rodríguez Sánchez, Julio; López Almansa, Francisco; Ledesma Villalba, Alberto (Asociación Chilena de Sismología e Ingeniería Antisísmica, 2019)
    Conference report
    Open Access
    En ingeniería sísmica, los registros disponibles suelen ser superficiales y, en consecuencia, los movimientos en las capas inferiores deben ser estimados conociendo el perfil estratigráfico del terreno; estos movimientos ...
  • Enabling Ada and OpenMP runtimes interoperability through template-based execution 

    Royuela Alcázar, Sara; Pinho, Luís Miguel; Quiñones, Eduardo (Elsevier, 2020-05)
    Article
    Open Access
    The growing trend to support parallel computation to enable the performance gains of the recent hardware architectures is increasingly present in more conservative domains, such as safety-critical systems. Applications ...
