El sistema de acondicionamiento de potencia es clave para el funcionamiento correcto del resto de sistemas eléctricos de un satélite. Los reguladores conmutados continua - continua son las piezas que enlazan los paneles ...
El treball parteix de la idea que l'arquitectura és essencialment geomètrica i vol demostrar que el coneixement de la geometria és imprescindible per a arribar a fer una obra d'arquitectura.<br/>S'estudien uns 30 exemples ...
The SDN (Software-Defined Networks) architecture separates the data and the control planes of the networks. It logically centralizes the control of a network in a central point that is an SDN controller, which acts as a ...
El control de convertidores de potencia conmutados CC/CC es un área de investigación muy activa tanto en electrónica de potencia como en teoría de control automático. Debido esencialmente, a la actual demanda de este tipo ...
The installation of power generation systems based on renewable energy sources has been increasing exponentially over the last decades. However, in spite of the well-known merits of such energy sources, the expansion of ...
The present doctoral thesis focuses on designing control schemes for three-phase three-wire voltage-sourced inverters connected to the grid under voltage disturbances. The research recognizes the large-scale integration ...
Un tema central en la ciencia y la tecnología es la exploración y explotación de sistemas cada vez más pequeños por medio de técnicas ópticas. A menudo, la longitud de onda viene dictada por el sistema de interés: los ...
Power system is undergoing an unpreceded paradigm shift: from centralized to distributed generation. As the renewable-based generations and battery storage systems are increasingly displacing conventional generations, it ...
The present PhD thesis analyzes the modelling and control of the two main topologies of large scale variable speed wind turbines, the doubly fed induction generator and the permanent magnet synchronous generator wind ...
Microgrids are the near future candidate to reduce the dependence on the carbon-based generation, towards a more environmentally friendly and sustainable energy paradigm. The popularization of the use of renewable energy ...
(English) The control strategies implemented in exoskeletons play a crucial role in determining the interaction between the device and user. However, it is unclear what is the most suitable control strategy and settings ...
(Enlish) In the past years, battery electric vehicles have been gaining market share. These vehicles are progressively seen as a viable option by customers of all kind. However, although manufacturers and research institutions ...
Distributed Generation (DG) provides an alternative to the Centralized Generation (CG) by means of generating electricity near to the end user of power with the employment of small-scale technologies to produce electricity, ...
Aquesta tesi presenta treball original i aplicat en l'àrea del control i la col·locació de sensors/actuadors (S/A) en sistemes de Control Actiu de Soroll (ANC). Primer, s'han aplicat tècniques de control i identificació ...
The multiphase synchronous buck converter is universally used today for powering low voltage, high current and high slew-rate loads, such as CPUs and other high performance digital ICs. This converter demands control ...
The last decades have witnessed impressive technical advances in all the fields of quantum science, including solid-state systems or atomic, molecular, and optical physics, allowing one to control materials at the microscopic ...
The emission and detection of light is a main pillar of both fundamental research and the advancement of modern technologies. From digital communications and quantum computing to novel cancer treatments and faded jeans, ...
The modelling of convective transport processes involving heat and mass transfer in an incompressible Newtonian fluid in cylindrical domains is a relevant research subject both for theoretical research and for industry. ...
En la tesis doctoral Convección térmica en un anillo cilíndrico en rotación se estudian diferentes aspectos de la dinámica lineal y no lineal de un fluido Boussinesqconfinado en un anillo cilíndrico, en rotación alrededor ...
(English) The main objective of this thesis is to propose solutions for implementing dynamic RAN slicing and Functional Split (FS) along with MEC placements in 5G/B5G. In particular, this thesis is divided into three parts. ...
