(2022-05-27)
El objeto de este trabajo es desarrollar una metodología integral de diseño mecatrónico de mecanismos paralelos tipo compliant, es decir, cuyo movimiento se consigue gracias a la deformación de determinados puntos del ...
Cosserat thermo-mechanics under finite deformations: theory and finite element implementation
(2022-05-23)
The objective of this thesis is to propose a theory that is able to capture specific phenomena during machining operations on metals. Recent investigations proved that dislocations-driven mechanisms at molecular or atomic ...
Multiple Sensor Monitoring of CFRP Drilling to Define Cutting Parameters Sensitivity on Surface Roughness, Cylindricity and Diameter
(MDPI, 2020-06-21)
Machining parameters affects the final quality of components made in carbon fiber reinforced plastic (CFRP) composite materials. In this framework, the work here presented aims at studying the right combination of cutting ...
Self-Tuning Algorithm for Tuneable Clamping Table for Chatter Suppression in Blade Recontouring
(MDPI, 2021-03-13)
The production and repair of blades for aerospace engines and energy turbines is a complex process due their inherently low stiffness and damping properties. The final recontouring operation is usually performed by milling ...
Effect of Land Use/Cover Changes on Urban Cool Island Phenomenon in Seville, Spain
(MDPI, 2020-06-12)
This paper analyses Seville’s surface urban heat island (SUHI) phenomenon, comparing spatial and temporal patterns of land surface temperature (LST) during July 1987, 2000 and 2017. Landsat data captured throughout three ...
A Comparison of Numerical Approaches for the Design of Mooring Systems for Wave Energy Converters
(MDPI, 2020-07-16)
This paper analyses the numerical outcome of applying three different well-known mooring design approaches to a floating wave energy converter, moored by means of four catenary lines. The approaches include: a linearized ...
