Design robust controllers for load reduction in wind turbines
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2013)
This thesis determines a design methodology of robust and multivariable controllers based on the H∞ norm reduction and on LPV (Linear Parameter Varying) techniques for load reduction in wind turbines. In order to do this, ...
Machine generated vertical vibration in elevators
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2013)
Vertical vibration deteriorates passenger comfort during an elevator travel. The drive system is a source of vertical vibration as well as the source of energy of the system. This report presents the results of a study of ...
Nanocomposites bioabsorbibles para aplicaciones biomédicas
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2013)
The longer life expectancy and the sports injuries have increased the need to address
chronic and/or orthopedic diseases which cannot be met by conventional healing techniques.
Tissue Engineering, combining the research ...
Development of biodegradable magnesium alloy scaffolds for tissue engineering
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2013)
Magnesium and its alloys are currently considered to be a promising metallic biomaterial. The increasing interest in magnesium alloys is due to their biocompatibility, biodegradability and in particular to their mechanical ...
Numerical modelling of cold crucible induction melting (CCIM) process and fabrication of high value added components of titanium and its alloys
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2013)
This dissertation concerns the development of a numerical modelling of cold crucible induction melting (CCIM) and the fabrication of high value added components of titanium and its alloys.
Titanium and its alloys have ...
Behavioral modeling for anomaly detection in industrial control systems
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2013)
In 1990s, industry demanded the interconnection of corporate and production networks. Thus, Industrial Control Systems (ICSs) evolved from 1970s proprietary and close hardware and software to nowadays Commercial Off-The-Shelf ...
Multi revolution finite element model to predict machining induced residual stresses in Inconel 718
(Elsevier, 2013)
Inconel 718 is commonly used in structural critical components of aircraft engines due to its mechanical thermal properties at high temperatures, which makes it to be considered as a difficult to machine material. In these ...
A sensibility analysis to geometric and cutting conditions using the particle finite element method (PFEM)
(Elsevier, 2013)
The (PFEM) is employed to simulate orthogonal metal cutting of 42CD4 steel. The objectives of this work are mainly three: The first one is to validate PFEM strategies as an efficient tool for numerical simulation of metal ...
Simulation of distortion due to machining of thin-walled components
(Elsevier, 2013)
The distortion of components is strongly related to the residual stress state induced by manufacturing processes like heat treatment, forming or machining. Each process step affects the initial stress state of the following ...
Direct control strategy for PMSMS in railway traction application
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2013)
En esta tesis se ha presentado y validado el control directo denominado DSC como una nueva propuesta para el control de motores de imanes permanentes en aplicaciones de tracción ferroviaria. Esta hipótesis ha sido analizada ...
