Actor-critic continuous state reinforcement learning for wind-turbine control robust optimization
(Elsevier, 2022-04)
[EN] The control of Variable-Speed Wind-Turbines (VSWT) extracting electrical power from the wind kinetic energy are composed of subsystems that need to be controlled jointly, namely the blade pitch and the generator torque ...
Microstructure and Phase Formation of Novel Al80Mg5Sn5Zn5X5 Light-Weight Complex Concentrated Aluminum Alloys
(MDPI, 2021-12-01)
In this work, three novel complex concentrated aluminum alloys were developed. To investigate the unexplored region of the multicomponent phase diagrams, thermo-physical parameters and the CALPHAD method were used to ...
Transient thermal parameters correlation of spacecraft thermal models against test results
(Elsevier, 2022-10)
There are always differences between the computer predicted temperatures of a spacecraft thermal model and the temperatures measured during the mandatory laboratory thermal tests. As a consequence, the model must be ...
Influence of process parameters on the particle-matrix interaction of WC-Co metal matrix composites produced by laser-directed energy deposition
(Elsevier, 2022-11)
The prediction of the in-service behaviour of metal-matrix composites produced by laser-directed energy deposition is a fundamental challenge in additive manufacturing. The interaction between the reinforce-ment phase and ...
On the friability of mussel shells as abrasive
(Elsevier, 2022-11)
The spread of raft-farming of mussels in river estuaries around the world produces about 1.4 million tons of shell waste which mainly ends up in landfills. In addition, the United Nations and the European Union promote the ...
Evaluation of the Radar Speed Cameras and Panels Indicating the Vehicles’ Speed as Traffic Calming Measures (TCM) in Short Length Urban Areas Located along Rural Roads
(MDPI, 2021-12-05)
Traffic calming measures (TCMs) are implemented in urban areas to reduce vehicles’ speed and, generally speaking, results are obtained. However, speed is still a problem in rural roads crossing small villages without ...
Managing Traffic Data through Clustering and Radial Basis Functions
(MDPI, 2021-03-05)
Due to the importance of road transport an adequate identification of the various road network levels is necessary for an efficient and sustainable management of the road infrastructure. Additionally, traffic values are ...
Analysis and Economic Evaluation of the Use of Recycled Polyamide Powder in Masonry Mortars
(MDPI, 2020-11-11)
Due to the considerable amount of waste plastics and polymers that are produced annually, the introduction of these waste products in construction materials is becoming a recurrent solution to recycle them. Among polymers, ...
A Series of Vertical Deflections, a Promising Traffic Calming Measure: Analysis and Recommendations for Spacing
(MDPI, 2020-05-13)
Traffic calming measures (TCM) are placed in urban areas to improve road safety, and among them, vertical TCMs are widely employed. Many researches are focused on the influence of the geometry of each measure on speed ...
Analysis of the Efficiency of Traffic Lights Turning Red in Case of Exceeding Speed Limit
(Universidad Nacional de Colombia, 2021-04)
Due to the presence of various traffic calming measures (TCM) and traffic lights in urban areas, the speed of vehicles is maintained low. Nevertheless, a problem arises in the frontier between urban and non-urban areas ...
