On the Use of a Simplified Slip Limit Equation to Predict Screw Self-Loosening of Dental Implants Subjected to External Cycling Loading
(MDPI, 2020-09-26)
Self-loosening of the prosthetic screws is a major mechanical problem affecting roughly 10% of dental implants, according to the literature. This phenomenon may lead to micro-movements that produce crestal bone loss, ...
Evaluating Disruptive Innovation Project Management Capabilities
(MDPI, 2020-12-22)
Firms must adapt to a business environment in constant flux. Economic and political factors and the constant interruption of new technologies force firms and organizations to change and to adapt, so that they are not left ...
Compound Formation And Microstructure Of As-Cast High Entropy Aluminums
(MDPI, 2018-03-09)
The aim of this work is to study the microstructure of four high entropy alloys (HEAs) produced by large scale vacuum die casting. Al40Cu15Mn5Ni5Si20Zn15, Al45Cu15Mn5Fe5Si5Ti5Zn20, Al35Cu5Fe5Mn5Si30V10Zr10, and ...
Optimization study of the structural HACFRA composition (Self Compacting Concrete Steel Fiber Reinforced)
(Instituto de Ciencias de la construccion Eduardo Torroja, 2015-03)
The interest of HACFRA (self compacting concrete reinforced with steel fibers), is the combination of the residual strength increase and cracking decrease compared to plain concrete by the introduction of steel fibers in ...
Design of an active reconfigurable 2R joint
(Springer, 2019-06-14)
The increasing flexibility requirements in the manufacturing processes has led to the development of novel reconfigurable mechanisms to be implemented in ma-chine heads and tables. This is the case of the reconfigurable ...
Research Trends in Pavement Management during the First Years of the 21st Century: A Bibliometric Analysis during the 2000–2013 Period
(MDPI, 2018-07)
A bibliometric analysis based on Scopus database was carried out to identify the global research trends related to pavement management area from 2000 to 2013, and to improve the understanding of the research topics in that ...
IRI Performance Models for Flexible Pavements in Two-Lane Roads until First Maintenance and/or Rehabilitation Work
(MDPI, 2020-01-22)
Pavement performance models play a vital role in any pavement management system. The Regional Government of Biscay (RGB) (Spain) manages a 1200 km road network and conducts pavement data collections, including the International ...
On the study of train-track dynamic interactions caused by rail welds on discrete supported rails
(Elsevier, 2014-06-15)
The paper studies the influence of rail weld dip on wheel-rail contact dynamics, with particular reference to freight trains where it is important to increase the operating speed and also the load transported. This has ...
Design of an optimised wheel profile for rail vehicles operating on two track gauges
(Taylor & Francis, 2013-01)
This paper sets out an optimum synthesis methodology for wheel profiles of railway vehicles in order to secure good dynamic behaviour with different track configurations. Specifically, the optimisation process has been ...
SEM and EDS Characterisation of Layering TiOx Growth onto the Cutting Tool Surface in Hard Drilling Processes of Ti-Al-V Alloys
(Hindawi Publishing Corporation, 2011)
Scanning electron microscopy (SEM) has been used to identify and analyse the secondary adhesion effect precursors formed during
the dry drilling processes of Ti-6Al-4V alloy over the rake face and flute of the drilling ...
