The efficacy of the energy management systems at dealing with energy consumption in buildings has been a topic with a growing interest in recent years due to the ever-increasing global energy demand and the large percentage ...
This dissertation formulates a proposal for a real time implementable energy management strategy (EMS) for plug-in hybrid electric vehicles. The EMS is developed to minimize vehicle fuel consumption through the utilisation ...
The global seismic activity is extensively studied and well characterized by seismic networks focused on the seismic hazards derived from earthquakes. However, a specific study on volcano seismicity is not widespread, due ...
This thesis deals with the further development of an existing underwater vehicle for autonomous navigation. The vehicle was conceived to navigate over the sea surface and, at certain fixed points, to dive vertically in ...
Sleep monitoring is of major importance for various medical areas such as the detection and treatment of sleep disorders, assessment of different medical conditions or medications' effects over sleep quality, and mortality ...
Due to the growing popularity of video-based methods for physiological signal measurement, and taking into account the technological advancements of these type of devices, this work proposes a series of new novel methods ...
Nowadays, energy management has gained attention due to the constant increment of energy consumption in industry and the pollution problems that this fact supposes. On this subject, one of the main industrial sectors, the ...
The present thesis is focused on the control of three-phase power converters using sliding-mode control (SMC) in abc frame. This work has been based on previous publications about the SMC applied to three-phase power ...
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 ...
Today, the most common form of mass-production semiconductor device fabrication is Complementary Metal-Oxide Semiconductor (CMOS) technology. The dedicated Integrated Circuit (IC) interfaces of commercial sensors are ...
The study of the seas is a field of science that is in constant development. At the technological level, in recent years, important advances have been made in the design of platforms and measurement systems for oceanographic ...
This thesis focuses on the control methods applied to current source resonant converters, especially in two different applications of switching power supplies and wire-less power transfer systems. In fact, the existing ...
The increasing use of DC electronic devices connected to mains lead to numerous complications of harmonic distortion and efficiency reduction in electrical energy transmission. These devices behave as a marked non linear ...
The environmental and economic benefits related to the reduction of both carbon dioxide emission and transmission losses have made distributed renewable generation systems became a competitive solution for future power ...
Condition Based Maintenance is a program that recommends actions based on the information collected and interpreted through condition monitoring and has become accepted since a decade ago by the industry as a key factor ...
Equipped with appropriate control strategies, permanent magnet (PM) machines are becoming one of the most flexible types of actuators for many industrial applications. Among different types of PM machines, five-phase BLDC ...
The application of the sliding mode control in power converters has a well-known inconvenient from the practical point of view, which is to obtain fixed switching frequency implementations. This thesis deals with the ...
The work underlying this Thesis, has contributed to the main study and characterization of diffusive systems. The research work has been focused on the analysis of two kind of systems. On the one hand, the dynamics of ...
This thesis deals with the automatic detection of features in signals, either extracted from photographs or captured by means of electronic sensors, and its possible application in the detection of morphological structures ...
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 ...
