Study of Astroloy powder compaction at high temperature under hydrostatic load using finite elements
(Elsevier, 2021)
The results of existing constitutive models describing the behaviour of metal powder during compaction processes are very different. This reveals the high sensitivity of the mechanical behaviour of porous materials to the ...
A general kinematic model for lubricated ball bearings based on the minimum energy hypothesis
(Elsevier, 2024)
Accurately predicting the performance of lubricated rolling elements is critical for certain key bearing applications. A widely employed simulation technique is quasi-static models, which although computationally efficient ...
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 ...
Dielectric Flow and Tab-Based Battery Thermal Management System For EV High Performance Application
(Elsevier, 2023)
From the perspectives of security, durability, and proper operation, effective temperature control via thermal management systems (TMSs) on lithium-ion batteries is crucial for electric vehicle use. In this regard, a novel ...
Stability tool for electric power systems with a high penetration of electronic power converters
(Elsevier B.V., 2022)
The increasing use of electronic converters is making possible the development of more sustainable, efficient, and reliable electric power systems, but it is also introducing new challenges that need to be addressed. Power ...
Perceived academic self-efficacy of adolescents and the relationship with physical activityAutoeficacia académica percibida de los adolescentes y la relación con la actividad física
(Federación Española de Asociaciones de Docentes de Educación Física (FEADEF), 2024-05-01)
Given the challenges and levels of competitiveness that exist at the educational level, it is necessary to analyze the different
factors that determine academic effectiveness, in consideration of sedentary tendencies and ...
Error estimation in current noisy quantum computers
(Springer Nature, 2024)
One of the main important features of the noisy intermediate-scale quantum (NISQ) era is the correct evaluation and consideration of errors. In this paper, we analyse the main sources of errors in current (IBM) quantum ...
Non-destructive experimental technique to determine ball contact load in rolling machine elements
(Elsevier, 2024)
Rolling machine elements, such as ball bearings, ball screws, or guiding systems are commonly used in diverse industrial applications. These components typically assume uniform load distribution among the balls or rely on ...
Synchronized Switching Modulation to Reduce the DC-Link Current in SRM Drives
(IEEE, 2020)
Switched Reluctance Machines (SRM) are emerging as a possible alternative in terms of cost and supply stability to rare earth based electric vehicle traction systems. However, because of the huge amounts of energy stored ...
Study of powder densification under hydrostatic loads at high temperatures using finite element method
(Elsevier, 2020)
Many different constitutive models that describe the behaviour of metal powder during hot isostatic processes are found in literature. A quantitative comparison of these material laws shows a huge discrepancy among the ...
