Pons Poblet, Josep Maria (Date of defense: 2014-09-16)
The present project is aimed to analyze the steel structure from an evolutionary point of view. The study¿s context has been the 20th century on the Catalan capital city in order to see how the historical, normative and ...
Dávalos Chargoy, César Emilio (Date of defense: 2014-06-19)
The aim of this work is to present a new procedure for modelling industrial processes that involve granular material flows, using a numerical model based on the Particle Finite Element Method (PFEM). The numerical results ...
Dialamishabankareh, Narges (Date of defense: 2014-03-12)
This thesis deals with the numerical simulation of welding processes. The analysis is focused either at global level, considering the full component to be jointed, or locally, studying more in detail the heat affected zone ...
Coll Sans, Abel (Date of defense: 2014-07-01)
Nowadays large part of the time needed to perform a numerical simulation is spent in preprocessing, especially in the geometry cleaning operations and mesh generation. Furthermore, these operations are not easy to automatize ...
Casariego Vales, Pedro (Date of defense: 2014-07-08)
Since a few decades ago, the cold-formed steel industry has developed a press-forming procedure to bend trapezoidal commercial steel sheeting into an arched shape. The main quality of these arches is to be self-supporting, ...
Moreno, E. (Elvira) (Date of defense: 2014-02-26)
The objective of this thesis is to develop and evaluate a methodology for the solution of the Navier-Stokes equations for Bingham Herschel-Bulkley viscoplastic fluids using stabilized mixed velocity/pressure finite elements. ...
Ortega, E. (Enrique) (Date of defense: 2014-05-12)
This work deals with the development and application of the Finite Point Method (FPM) to compressible aerodynamics problems. The research focuses mainly on investigating the capabilities of the meshless technique to address ...
Rodríguez Prieto, Juan Manuel (Date of defense: 2014-03-06)
Metal cutting or machining is a process in which a thin layer or metal, the chip, is removed by a wedge-shaped tool from a large body. Cutting is a complex physical phenomena in which friction, adiabatic shear bands, ...
Bernat Masó, Ernest (Date of defense: 2014-02-07)
A significant number of buildings are supported by load-bearing masonry walls. The preservation of these worldwide used structures is a sustainable alternative. However, there is little research about the structural response ...
Musté Rodríguez, Marta (Date of defense: 2013-12-05)
In canine traumatology, one of the most common knee pathologies is torn cruciate ligament (ACL), the diagnosis and treatment costs were 1.32 billion dollars in the U.S. during 2003. The short-term effects are instability ...
Pérez Guindal, Elsa (Date of defense: 2013-12-05)
The knee joint is the largest and most complex both in humans and in canines. The internal forces that govern it, are not known exactly. Canine knee injuries are recurrent, especially in the anterior cruciate ligament, a ...
González González, David (Date of defense: 2014-01-29)
Today, 3.5 and 4G systems including Long Term Evolution (LTE) and LTE-Advanced (LTE-A) support packet-based services and provide mobile broadband access for bandwidth-hungry applications. In this context of fast evolution, ...
Bonada Bo, Jordi (Date of defense: 2014-01-23)
Cold-formed thin-walled steel sections are frequently used in pallet rack structures. This type of cross-sections are normally used as a columns and contains perforations uniformly distributed enabling the connection between ...
Pérez Martínez, M. (Marco) (Date of defense: 2012-02-06)
Composite laminates offer decisive advantages compared to more traditional materials, especially in structural applications where weight is a design-limiting factor. However, they have also shown a susceptibility to impact ...
Kouhi Esfahani, Mohammad (Date of defense: 2013-09-30)
This work covers a contribution to two most interesting research elds in aerodynamics, the fi nite element analysis of high-speed compressible flows (Part I) and aerodynamic shape optimization (Part II). The fi rst part ...
Diego Íñiguez, Javier (Date of defense: 2013-07-03)
Cell migration is a fundamental element in a variety of physiological and pathological processes. Alteration of its regulatory mechanisms leads to loss of adhesion and increased motility, critical steps in the initial ...
Silva Araujo Monteiro, Virginia (Date of defense: 2013-06-10)
La propuesta de una vejiga artificial es un obstáculo a trasponer. El cáncer de vejiga está entre los casos más frecuentes de enfermedades oncológicas en Estados Unidos y Europa. Ese cáncer es considerado un problema médico ...
Kamram, Kazem (Date of defense: 2013-06-21)
The development of efficient algorithms to understand implosion dynamics presents a number of challenges. The foremost challenge is to efficiently represent the coupled compressible fluid dynamics of internal air and ...
Paredes López, Jairo-Andrés (Date of defense: 2013-11-11)
Esta tesis surge de la necesidad de establecer un método racional y práctico para identificar, a través del cambio de las frecuencias naturales , el daño en estructuras de hormigón armado. Por lo que se desarrolla un nuevo ...
Sánchez Molina, David (Date of defense: 2013-11-07)
