The main object of study of this thesis is the development of scalable and robust solvers based on domain decomposition (DD) methods for the linear systems arising from the finite element (FE) discretization of transient ...
The fast evolution of data analytics platforms has resulted in an increasing demand for real-time data stream processing. From Internet of Things applications to the monitoring of telemetry generated in large datacenters, ...
In the last decades, high-performance large-scale systems have been a fundamental tool for scientific discovery and engineering advances. The sustained growth of supercomputing performance and the concurrent reduction in ...
The combination of unique properties -high electrical mobility, thermal conductivity, transparency and mechanical flexibility- make graphene promising for a wide variety of applications, including transparent electrodes, ...
(English) Deep learning techniques have an enormous impact on the state-of-the-art in many fields, such as computer vision, natural language processing, audio analysis and synthesis, and many others. The increasing computing ...
La heterogeneidad de la conductividad hidráulica es bien conocida, pudiendo cambiar varios órdenes de magnitud en poca distancia. Esto afecta nuestras observaciones de los procesos naturales. Para poder explicar la realidad ...
System codes along with necessary nodalizations are valuable tools for thermal hydraulic safety analysis. Qualifying both codes and nodalizations is an essential step prior to their use in any significant study involving ...
Els avanços en neurociència han portat el desenvolupament de models complexes de neurones artificials semblants a les seves contraparts biològiques. Aquests models han millorat la funcionalitat de les xarxes neuronals ...
In recent years, high-performance computing research became essential in pushing the boundaries of what men can know, predict, achieve, and understand in the experimented reality. HPC Workloads grow in size and complexity ...
In many situations, the resources in organizations are employed to satisfy some demand (or services) requirements, which are repeated with some periodicity. These recurrent services appear in a large variety of processes ...
El inminente lanzamiento de la misión Soil Moisture and Ocean Salinity (SMOS, humedad del terreno y salinidad del mar) de la Agencia Espacial Europea (ESA) permitirá la recuperación sistemática y a escala global de la ...
L’oceanografia per satèl•lit ha esdevingut una integració consolidada de les tècniques convencionals de monitorització in situ dels oceans. Un coneixement precís dels processos oceanogràfics i de la seva interacció és ...
(English) The Global Navigation Satellite Systems (GNSS) are large, stable and calibratecl sets of spaceborne L-band microwave transmitters with very well characterized properties. They provide global and permanent coverage ...
Searching and tracking are important behaviours for a mobile service robot to assist people, to search-and-rescue and, in general, to locate mobile objects, animals or humans. Even though searching might be evident for ...
Arctic sea ice plays a central role in the Earth’s climate. Changes in the sea ice on seasonal-to-interannual timescales impact ecosystems, populations and a growing number of stakeholders. A prerequisite for achieving ...
Modelling seawater intrusion (SWI) has evolved from a tool for understanding to a water management need. Yet, it remains a challenge. Difficulties arise from the assessment of dispersion coefficients and the complexity of ...
Freshwater quality and availability in coastal areas are affected by seawater intrusion into coastal aquifers. While coastal water quality and coastal ecosystems can be significantly affected by pollutants discharged into ...
Este trabajo resuelve el problema de gran interés para la industria aeronáutica: el cálculo de la sección recta (RCS) de blancos radar complejos en tiempo real. Para ello basta una estación de trabajo con un acelerador ...
The PhD project, entitled "Second harmonic generation in disordered nonlinear crystals: application to ultra-short laser pulse characterization", is devoted to the study of second harmonic generation in nonlinear ferroelectric ...
Photonic crystals emerged at the end of the last decade as a new frame to control the interaction between radiation and matter. The potential advances that such structures could report in photonics technology has lead to ...
