Effect of Added Mass Location on Manual Wheelchair Propulsion Forces
(2020-01-01)
This study investigated the influence of mass distribution on the handrim forces during manual propulsion in four different mobility tasks: Straightforward motion at self-selected speed; straightforward sprint; zero radius ...
The influence of handrim design on the contact forces on hands'surface: a preliminary study
(Elsevier B.V., 2014-11-01)
This study is aimed at investigating how contact forces are distributed over the hand's surface during manual wheelchair propulsion with two different designs of handrim. Twenty able-bodied subjects performed a ...
Possible Means of Electrostatic Propulsion According to the Mbelek–Lachièze-Rey Scalar-Tensor Theory of Gravitation
(Springer, 2018-07)
As was shown recently, the scalar-tensor theory of gravitation proposed by Mbelek and Lachièze-Rey allows for a possible explanation of the forces reported in asymmetric microwave cavities. We show here that the theory in ...
Diversity of self-propulsion speeds reduces motility-induced clustering in confined active matter
(Royal Soc Chemistry, 2021)
Self-propelled swimmers such as bacteria agglomerate into clusters as a result of their persistent motion. In 1D, those clusters do not coalesce macroscopically and the stationary cluster size distribution (CSD) takes an ...
Multi-disciplinary design optimization for conceptual design of hybrid-electric aircraft
(Universidade Federal de UberlândiaBrasilEngenharia Aeronáutica, 2020)
Análise numérica das características aerodinâmicas de uma asa de baixo alongamento com propulsão distribuída
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA MECÂNICAPrograma de Pós-Graduação em Engenharia MecanicaUFMG, 2020-06-15)
Distributed propulsion concept expands the boundaries of aircraft designs, therefore, the study of aerodynamic effects due to propulsion/wing interaction is extremely important for the elaboration of a wing as efficient ...
