Improving autonomous driving systems with CPU extensions for point cloud processing
(English) Autonomous Driving Systems (ADS) are at the cusp of large-scale adoption, promising accident reduction and market potential. However, the complex software and sensor data pressure for better hardware support in ...
Procesamiento mediante extrusión de material del termoplástico híbrido PLA/PHB: caracterización mecánica
(English) In this thesis, the mechanical behavior of parts manufactured by Material Extrusion Modeling (MEX) has been evaluated, using a copolimer of polylactic acid (PLA) and polyhydroxybutyrate (PHB), commercially known ...
Optimization with spin glass models
(English) With applicability on almost every aspect of our lives, optimization problems are ubiquitous to a broad range of fields within both scientific research and industrial environments. As such, these are growing in ...
New approach of power calculation for droop-controlled inverters supplying nonlinear loads
(English) This thesis framework is that of the control of single-phase inverters in alternate current (AC) microgrids. In this context, voltage sourced inverters present difficulties in coping with power quality issues ...
Hipòtesis sobre una línia : nuclis urbans i estacions a les línies interiors catalanes
(English) "Hypothesis on a Line" analyses the impact that the construction of the railway has had on the urban centres along the interior lines of the Catalan network. The integration of a territorial mobility infrastructure ...
Propagation of polarized light through turbid media: application of LiDAR technology in foggy environments
(English) In recent times, there has been a growing interest in LiDAR imaging systems for outdoor applications involving computer vision, such as automotive systems, surveillance, and robotics. LiDAR sensors have the ability ...
Modelo de priorización de inversiones de soluciones tecnológicas en smart buildings con criterios de desarrollo sostenible
(English) This Doctoral Thesis addresses aspects of interest for designers, promoters, owners, and managers of office buildings, with the intention of providing clarity on the Smart Building paradigm, as well as identifying ...
Manuel de Solà-Morales, escritura y pensamiento
(English) The written work of Manuel de Solà-Morales deserves a central place in his intellectual biography, along with the pedagogical experience and the urban projects he developed; teaching, practice and writings are ...
Escenarios hacia una economía circular de los plásticos: caracterización del sector del envasado y evaluación de la idoneidad del reciclado open loop de la fracción mezclada de los residuos de envase
(English) This thesis aims to deepen in the understanding of the circular economy of plastics through a scientific and design approach. It has focused on packaging waste as it is the sector with the highest priority and ...
Análisis comparativo del ciclo de vida de edificaciones construidas con prefabricación industrializada en latitudes mediterránea y tropical
(English) This research focuses on the study and comparative analysis of buildings constructed with industrialized prefabrication systems, based on the premise that industrialization implies resource optimization, technological ...
Contributions to eco-friendly satellite lean design for a sustainable space environment
(English) Currently, half of the satellites do not reach 20% of their expected lifetime. The possibility of recycling these "zombie satellites" (ZS) with limited capabilities would optimize this on-orbit infrastructure, ...
Innovative modular pour plating microbiology culture media technology
(English) The current methods used in microbiological quality analysis rely on the use of traditional and manual methods, such as the pour plate method. The need to perform more analyses of different matrices makes it ...
Objective evaluation on the effectiveness of vergence vision training based on the analysis of eye movements
(English) When an object of interest is detected in the visual field, a saccadic movement is made and the attention and gaze are centred on it. During this visual fixation, optokinetic eye movement occurs to maintain the ...
Canonical realizations of Bondi-Metzner-Sachs–like symmetries in field theory
(English) The BMS group appears as an infinite-dimensional group of isometries of asymptotically flat spacetimes first introduced by Bondi, Metzner, van der Burg, and Sachs in 1962. This group has gained interest recently ...
Tijuana, un puzle de fragmentos urbanos. Origen y evolución de una ciudad fronteriza
(English) The present research is an urban study about Tijuana, whose purpose is to understand the historical processes that have outlined it from its regional origins, the evolution of urban processes and its built ...
Architectural strategies to enhance the latency and energy efficiency of mobile continuous visual localization systems
(English) The emergence of new applications such as autonomous machines (e.g., robots or self-driving cars) and XR (Extended Reality) promises to revolutionize how society interacts with technology in the rapidly advancing ...
Ground and marine resilient integration technology of multi-source sensors for navigation and positioning
(English) The present thesis focuses on the resilient terrestrial and marine technological integration for navigation and positioning based on the Global Navigation Satellite System (GNSS), the Inertial Navigation System ...
Valorar i conservar el patrimoni arquitectònic en un territori perifèric. Continuïtats i discontinuïtats a la Comissió Provincial de Monuments Històrics i Artístics de Lleida, 1844-1938
(English) The 19th century witnessed both the initial and the most significant steps to be taken by the Spanish government with respect to preserving architectural heritage, in steps that were closely linked to the country's ...
Contribution to prognostics and health management of complex systems. Application to energy systems
(English) This thesis presents contributions to model-based Prognostics and Health Management (PHM) for online Remaining Useful Life (RUL) forecasting of degraded systems. The major issue in such a prognostics approach is ...
Numerical optimisation of worm locomotion on frictional substrates
(English) Optimal control theory provides a framework to determine optimal inputs for mechanical systems modeled as initial value problems. The resulting minimisation problem may be solved with known direct and indirect ...
