Reusability and Flexibility in Parametric Surface-based Models: A Review of Modelling Strategies
(Taylor and Francis Ltd., 2021)
CAD systems are indispensable tools in the product design and development process. Through the creation of parametric 3D models,they increase productivity, enable the design of highly complex parts, improve ...
An analytical approach to calculate stress concentration factors of machined surfaces
(Elsevier Ltd., 2021)
Machining operations affect the properties of the final surface layer, and these can impact on its functional per- formance, particularly on fatigue behaviour. Among the properties of the machined surface, surface topography ...
Retinal thickness predicts the risk of cognitive decline in Parkinson's disease
(Wiley, 2021)
Objective: To analyze longitudinal changes of retinal thickness and their predictive value as biomarkers of disease progression in idiopathic Parkinson’s disease (iPD).
Methods: Patients with Lewy body diseases (LBDs) ...
A coupled 3D wear and fatigue numerical procedure: Application to fretting problems in ultra-high strength steel wires
(Elsevier Ltd., 2021)
This work presents a coupled 3D wear and fatigue numerical procedure for fretting problems in ultra-high strength steel wires that combines Archard’s wear equation with the Smith–Watson–Topper parameter to predict crack ...
Sensor signal selection for tool wear curve estimation and subsequent tool breakage prediction in a drilling operation
(Taylor & Francis, 2021)
Tool condition monitoring have an important role in machining processes to reduce defective component and ensure quality requirements. Stopping the process before the tool breaks or an excessive tool wear is reached can ...
Human‑centred design in industry 4.0: case study review and opportunities for future research
(Springer, 2021)
The transition to industry 4.0 has impacted factories, but it also afects the entire value chain. In this sense, human-centred factors play a core role in transitioning to sustainable manufacturing processes and consumption. ...
A novel formulation for radial fretting wear: Application to false brinelling in thrust bearings
(Elsevier Ltd., 2021)
Radial fretting is defined as the damage caused by the relative motion of a ball under a variable normal load. The conducted experimental tests proved the existence of this damage even in contacting bodies with similar ...
Computerized generation and tooth contact analysis of spherical gear couplings for high misalignment applications
(Elsevier Ltd., 2021)
Spherical gear couplings are a type of toothed coupling where the external spline usually requires highly crowned tooth surfaces to absorb high misalignments. The teeth of the external spline (or hub) may present cross ...
Web Augmentation as a Technique to Diminish User Interactions in Repetitive Tasks
(IEEE, 2021)
The use of the World Wide Web has experienced extraordinary growth in the last decades. The Web has become the main source of information for millions of users. The number of websites offering content to users is countless. ...
Ofermod y heroísmo humilde: sobre la interpretación de Tolkien
(Universidad de La Laguna, 2021)
El presente trabajo estudia la interpretación del heroísmo germano por Tolkien tomando como punto de partida su ensayo-poema «The Homecoming of Beorhtnoth Beorhthelm’s Son» sobre La Batalla de Maldon. A través de textos ...
