Lack of association of cranial lacunae with intracranial hypertension in children with Crouzon syndrome and Apert syndrome: a 3D morphometric quantitative analysis
(Springer Berlin Heidelberg, 2019)
Purpose Cranial lacunae (foci of attenuated calvarial bone) are CT equivalents ofBcopper beating seen on plain skull radio-graphs in children with craniosynostosis. The qualitative presence of copper beating has not been ...
A mechanistic model to predict cutting force on orthogonal machining of Aluminum 7475-T7351 considering the edge radius
(Elsevier B.V., 2019)
The ploughing force related with action of edge radius is an important factor which influences flow stress, chip formation or surface integrity. Some fraction of the cutting forces are called parasitic (additional) forces ...
How to negotiate with dominant suppliers? A game-theory perspective from the industry
(Universidad Politécnica de Madrid; Asociación de Ingenieros para el Desarrollo de la Ingeniería de Organización, 2019)
The negotiation with dominant suppliers usually drives to locked-in situation in which buyers have no choice but to accept the given conditions. Commonly found in the industry, there is a need to provide new insights to ...
On the Role of a ZDDP in the Tribological Performance of Femtosecond Laser-Induced Periodic Surface Structures on Titanium Alloy against Different Counterbody Materials
(MDPI, 2019)
Laser-induced periodic surface structures (LIPSS, ripples) with ~500–700 nm period were produced on titanium alloy (Ti6Al4V) surfaces upon scan processing in air by a Ti:sapphire
femtosecond laser. The tribological ...
Artificial Neural Network Based Reinforcement Learning for Wind Turbine Yaw Control
(MDPI AG, 2019)
This paper introduces a novel data driven yaw control algorithm synthesis method based on Reinforcement Learning (RL) for a variable pitch variable speed wind turbine. Yaw control has not been extendedly studied in the ...
Analysis of technological architectures for the new paradigm of the industry 4.0Análisis de arquitecturas tecnológicas para el nuevo paradigma de la industria 4.0
(DYNA Publishing, 2019)
The present work defines an interoperable and scalable architecture that will allow the servitization of the machine tool sector. ICT and the Internet of Things make possible to interconnect different devices and controllers, ...
Design of a Solid-State Circuit Breaker for a DC Grid-Based Vessel Power System
(MDPI, 2019)
Electric propulsion and integrated hybrid power systems can improve the energy efficiency
and fuel consumption of different kinds of vessels. If the vessel power system is based on DC grid
distribution, some benefits ...
Development of a Modular Fretting Wear and Fretting Fatigue Tribometer for Thin Steel Wires: Design Concept and Preliminary Analysis of the Effect of Crossing Angle on Tangential Force
(MDPI AG, 2019)
This work presents the design of a modular ad-hoc fretting fatigue and fretting wear tribotester for thin steel wires. The working principles of the diffrent modules are described, such as the displacement and contact ...
Automation of Simulation Based Design Validation and Reporting of a Valve Family
(Elsevier B.V., 2019)
Valves are mechanical devices for controlling fluid-flow in pipes of different diameter and service pressures used in several industry sectors. Most demanding industry sectors add custom design requirements and require ...
Neuro-Sliding Control for Underwater ROV’s Subject to Unknown Disturbances
(MDPI, 2019)
Proposed in this paper is a model-free and chattering-free second order sliding mode control(2nd-SMC) in combination with a backpropagation neural network (BP-NN) control scheme for underwater vehicles to deal with external ...
