Impact of COVID-19 on the Use of Public Transport Differs According to Social Class: a Case Study of Donostia-San Sebastian City Bus System
(Scientific Research Publishing, 2023-10-31)
Almost three years into the pandemic, COVID-19 continues to have an impact on mobility around the world. Public transport was particularly hindered, since people may perceive it as unsafe and decide to avoid it. Many studies ...
Improving the precision of recordings acquired with digital occlusal analyzers: A dental technique
(Elsevier, 2023-09-01)
A technique to improve the precision of recordings acquired with the 2 main digital occlusal analyzers on the market (T-Scan and OccluSense) is presented. This technique consists of using digital occlusal analyzers with a ...
Analysis and Characterization of the Behaviour of a Variable Geometry Structure
(SAGE, 2007-11)
The study about a variable geometry truss is presented. The first step is a kinematic design and later an analysis using the MSC/Adams code. Then, the finite-element method with the MSC/Nastran code was used to develop a ...
Evaluation of efficiency and mechanical properties of Inconel 718 components built by wire and powder laser material deposition
(Emerald Publishing Limited, 2017-10-17)
PurposeThe purpose of this paper is to evaluate and compare powder and wire laser material deposition (LMD) processes.Design/methodology/approachIn the present paper, Inconel 718 tensile test probes were built layer by ...
Internal characterization and hole formation mechanism in the laser percussion drilling process
(Elsevier, 2013-09-09)
Laser percussion drilling is increasing its relevance in many industrial applications, being used particularly in the aircraft industry in performing the micro-holes in nickel based alloys turbine blades for cooling, or ...
Repeatability and reproducibility of 2 digital occlusal analyzers for measuring the right- and left-side balance of occlusal contact forces: An in vitro study
(Elsevier, 2023-09-01)
Statement of problem. Although different digital occlusal analyzers have been marketed, comparative studies are lacking. Purpose. The purpose of this in vitro study was to compare the repeatability and reproducibility of ...
New Transport Visual Mapping Method Combining Time, Cost and Sustainability Applied to the Barcelona Region
(Open Access Library Journal, 2022-11-29)
This article presents a new methodology (Visual Mapping Method of Transport: VMMT) in order to produce practical maps easy to understand for transport users. These maps would be really useful to identify what the most ...
Numerical assessment of the analytical models used to determine flexural and shear moduli in I-Beams when the tensile and compressive moduli are different
(Elsevier, 2020-01-30)
The different compressive and tensile moduli of fibre reinforced composites have been considered in the analysis of the flexural and shear moduli of I-beams. Firstly, the neutral axis has been determined analytically and ...
Numerical assessment of an experimental procedure applied to DCB tests
(Elsevier, 2020-02)
Numerical analysis of the analytic model of an experimental procedure to determine the crack length, the compliance and the energy release rate has been developed. As a first step, bending tests at different spans have ...
Rigid pavement performance models by means of Markov Chains with half-year step time
(Taylor & Francis, 2019-07-03)
[EN] Pavement management systems employ pavement performance models to plan the most effective allocation of public funds. The most used models are the deterministic and the probabilistic or stochastic ones. Among stochastic ...
