El aumento de la competencia en el área de la fabricación moderna ha propiciado una mayor preocupación por la reducción de los costes, por el aumento de la calidad del producto y por la reducción progresiva del tiempo entre ...
(English) People with spinal cord injury (SCI) may suffer lifelong sequels that influence every aspect of their lives, including motor and/or sensory impairment, difficulty breathing and/or swallowing, bladder/bowel weakness, ...
En aquest treball s'ha realitzat una anàlisi de la junta T-bolt aplicada a la unió de laminats gruixuts amb elements metàl·lics. Més concretament, l'estudi es centra en el tipus de juntes T-bolt emprades en la unió entre ...
The acoustic field inside a car cabin for low driving speeds is dominated by the engine or the tire noise. However, for mid to high velocities, the noise generated by the interaction of the car with the external air becomes ...
La tesi "Contribució a l'estudi de l'acústica dels tubs axisimètrics" és un treball centrat en l'estudi del comportament acústic dels tubs dels instruments musicals de vent amb simetria de revolució en el qual es fa ...
La present tesi doctoral s’ha centrat en el repte d’aconseguir, mitjançant Fabricació Additiva (FA), models per a assaig quirúrgic, sota la premissa que els equips per fer-los haurien de ser accessibles a l’àmbit hospitalari. ...
One of the main problems presented due to the defects in the profiles of the railway wheels is the generation of vibrations and noise, and their propagation towards the environment. Defects in wheels, such as surface pitting ...
The present work composes a contribution towards the Construction of World models for its implementation in 'Agile Manufacturing Architectures', aiming to take a step further the control programs for manufacturing systems, ...
This thesis is focused on the enhancement and development of advanced methodologies for the dynamic characterisation of resilient elements used in railway applications. On the one hand, this thesis proposes several ...
In recent decades, there has been a digitalization in all areas and faetones have not been been exempt from of this phenomenon, incorporating CAD I CAM I CAE systems, as well as automatas, robots, and real-time control ...
This thesis is the result of collaboration between the university (UPC) and the company (Fluidra SA) within the framework of the program of industrial doctorates of the agency AGAUR (Agencia de Gestión de Ayudas Universitarias ...
The production of components of the moulds and dies sector is increasingly demanding. On the one hand, a better manufacturing quality is required, that requires, among other aspects, the improvement of the surface finish, ...
La principal causa de las vibraciones generadas por la circulación de un tren reside en el contacto rueda-carril, concretamente en las fluctuaciones de la fuerza de contacto provocadas por las irregularidades del perfil ...
Since the first models developed in the late 19th century, the applications of piezoelectric materials have been progressively growing in number. The capacity of these materials to couple electric and mechanic fields makes ...
(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 ...
Els robots caminadors presenten alguns avantatges respecte als tradicionals robots mòbils amb rodes, que es resumeixen en major mobilitat i capacitat de superació d'obstacles. Un dels principals problemes actuals en el ...
This thesis is focused on the calibration of the Acoustic Emission (AE) technique to detect and identify damage mechanisms in tool steels. The AE measurement procedure has been calibrated for two mechanical tests: fracture ...
Lab-on-a-Chip (LOC) integrated microfluidics has been a powerful tool for new developments in analytical chemistry. These microfluidic systems enable the miniaturization, integration and automation of complex biochemical ...
La tesi descriu dos algorismes relatius al transport públic que actuen en sèrie. El primer genera una xarxa d'autobusos urbans entesa com a un conjunt de línies o be en modifica una de ja existent de forma que minimitzi ...
The thesis presented is performed with the aim of studying the effect of electropulses (EPs) in machining processes such as drilling and round turning processes for different materials. When the EPs of short duration are ...
