Study of the structural behaviour and analytical characterization of wire-race slewing bearings
(2022-03-25)
La presente tesis doctoral tiene como objetivo presentar los últimos avances en el campo de los rodamientos de vuelco con pista de rodadura alámbrica (wire-race bearings). Debido a la escasa literatura científica disponible ...
A skid resistance prediction model for an entire road network
(Elsevier Ltd., 2020-11-30)
[EN]This article predicts the available minimum skid resistance in the road network of Biscay (Spain) with data collected in the summer season when friction values are at a minimum. Firstly, it was observed that pavement ...
Active flow control on airfoils by reinforcement learning
(Elsevier, 2023-11-05)
Active flow control is a widespread practice for airfoil aerodynamic performance enhancement. Within active flow control, reactive strategies are very effective, but the adequate design of these strategies is often complex. ...
Influence of the Geometrical Design on Ball and Crossed Roller Wire Race Bearing Behavior under Axial Load
(Elsevier, 2020-12-05)
Wire bearings are becoming popular these days in applications such as defence, robotics, medical devices or shipping industry. They provide weight and inertia reductions, good shock load and vibration absorbing capacity, ...
Comparative study of finishing techniques for age-hardened Inconel 718 alloy.
(Elsevier, 2021-11-20)
Inconel 718 is a widely used alloy in the aeronautic sector due to its excellent mechanical
and corrosion wear resistance under high temperature conditions. However, its good
mechanical properties can be a double edge ...
Friction improvement via grinding wheel texturing by dressing
(Springer, 2020-05-20)
The economic and environmental cost of friction in machinery and transport is significantly remarkable, the machine tool being one of the most affected. In this sector, the movements are fully affected by the friction ...
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 ...
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 ...
