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 ...

(2020-07-16)
a tecnología ¿Single Point Incremental Forming¿ (SPIF) muestra un gran potencial para producir competitivamente series pequeñas de piezas de diversas aleaciones metálicas. Sin embargo, pese a las ventajas que presenta, ...
A Review on Strain Gradient Plasticity Approaches in Simulation of Manufacturing Processes
(MDPI, 2020-09-03)
Predicting the performances of a manufactured part is extremely important, especially for industries in which there is almost no room for uncertainties, such as aeronautical or automotive. Simulations performed by means ...
Corrosion Fatigue Numerical Model for Austenitic and Lean-Duplex Stainless-Steel Rebars Exposed to Marine Environments
(MDPI, 2020-09-10)
Steel rebars of structures exposed to cyclic loadings and marine environments suffer an accelerated deterioration process by corrosion fatigue, causing catastrophic failure before service life ends. Hence, stainless steel ...
Analysis of Photodiode Monitoring in Laser Cutting
(MDPI, 2020-09-19)
The paper presents the results of an analysis based on the photodiode monitoring signals obtained during the laser cutting of aluminum and stainless steel plates. The mean level of the monitoring signal was measured and ...
On the Relationship between Mechanical Properties and Crystallisation of Chemically Post-Processed Additive Manufactured Polylactic Acid Pieces
(MDPI, 2020-04-18)
Nowadays, improvement of the surface finish of parts manufactured by fused deposition modelling is a well-studied topic. Chemical post-treatments have proven to be the best technique in terms of time consumption and ...
Effect of WEDM Process Parameters on Surface Morphology of Nitinol Shape Memory Alloy
(MDPI, 2020-11-03)
Nickel–titanium shape memory alloys (SMAs) have started becoming popular owing to their unique ability to memorize or regain their original shape from the plastically deformed condition by means of heating or magnetic or ...
Chatter avoidance in the milling of thin floors with bull-nose end mills: Model and stability diagrams
(Elsevier, 2011-01)
The milling of thin parts is a high added value operation where the machinist has to face the chatter problem. The study of the stability of these operations is a complex task due to the changing modal parameters as the ...
Integración de las ecuaciones de la dinámica de sistemas multicuerpo mediante diferencias centrales de orden dos.
(2019-10-23)
Se ha desarrollado una metodología de análisis de la dinámica de sistemas multicuerpo para sistemas formados por sólidos rígidos. La novedad reside en que el sistema de ecuaciones diferenciales de segundo orden se resuelve ...
