Aquesta tesi tracta el problema del posicionament de robots mòbils quan, en el decurs del moviment, es realitzen mesures angulars relatives al robot de l'orientació de la recta entre un dels seus punts i punts de l'entorn ...
Selective laser melting process is an additive manufacturing technique that allows obtaining, from a 3D model, a physical model through a layer-by-layer manufacturing strategy. Several machines are commercially available, ...
During the design phase, it creates and transforms ideas into products. It needs to know the manufacturing aspects for ensuring success and calculating the product cost while developing of designs. However, the choice one ...
El desarrollo de la sostenibilidad en la edificación ha realizado un gran avance en los últimos diez años, mejoras en la eficiencia energética de los edificios con la incorporación del certificado de eficiencia energética ...
La selección de centros de mecanizado de alta velocidad es un proceso complejo que requiere de mucha experiencia, puesto que en él intervienen un gran número de variables, tanto tecnológicas como económicas. Existen ...
Modelo de predicción de la geometría final de una pieza de chapa, radio y ángulo de doblado final, producida mediante un proceso de doblado al aire.
En el proceso de diseño se toman decisiones que pueden afectar a la fabricabilidad del producto. Cuando el diseñador es experto, considera las limitaciones, las propiedades y el coste de fabricación en la fase de materialización ...
The main motivation of this work was to analyse the feasibility of the current stent’s manufacturing process to produce the new bioresorbable stents (BRS) as well as study new manufacturing methods. Fibre Laser Cutting ...
Nontraditional manufacturing processes (NTM) appeared to answer the growing demands of market productivity. Needs of higher quality products in less time and new demands such as new exotic work materials, innovative geometric ...
The development of new products with micro-metric characteristics and complex geometries has been a manufacturing trend in different industrial sectors, particularly for electronic, military, biomedical and aerospace ...
Polymeric materials, which are suitable for high performance applications for example human implants are one of the most expensive available polymers. Standard injection micromoulding process, dedicated for mass production, ...
The use of adhesive joints in industrial structural applications is currently growing. Nevertheless, the designing process is still a challenge for engineers because there is a lack of effective models to predict their ...
The primary objective of this research is to modify the models regularly used to record and monitor the implementation costs of public works projects from the perspective of the promotor, the project directors or the project ...
El uso de los composites en la industria aeronáutica ha experimentado un fuerte crecimiento en los últimos años debido a la utilización de componentes de composite que realizan funciones estructurales. A menudo, para ...
This document presents a methodology that (using tunable finite element models) allow validating during the development phase of the project, the behavior that equipment and mechanical systems will have once they are ...
La feina feta en aquest treball de tesis s'ha desenvolupat a partir de tres objectius vertebradors, que fonamentalment són:<br/>·El primer dels objectius d'aquest treball de tesis és presentar un recull dels factors que ...
Triple negative breast cancer (TNBC) accounts for 15-20% of the breast cancers and displays an aggressive profile, poor prognosis, high relapse risk and does not have a targeted therapy. In the last years, breast cancer ...
In this thesis two all-steel BRB have been designed, manufactured and tested, and both satisfy the testing protocols required by EU and US codes. They are composed of a steel slotted restraining unit which stabilizes the ...
Since the beginnings of the automotive driven with internal combustion engines all the cycles used in the alternative motors share a thermal characteristic, a large amount of heat released by the fuel is lost in the form ...
Advanced joining technologies such as bonded joints play an important role to develop more efficient and durable structures. The present Thesis gives a step forward and proposes different solutions to characterise the ...
