This paper provides a comprehensive explanation for the lift force acting on freely deformable bubble rising in linear shear flow and examines how scales with undisturbed rate cases governed by different mechanisms. Four distinct mechanisms are identified from previous studies, associated bubble-induced vorticity dynamics outlined. We provide theoretical framework to qualitatively explain terms...

Submit Manuscript | http://medcraveonline.com electromagnetic wave was firstly shown by Oleinik [4]. However, the theoretical proof of the attraction possibility was given by Kazantsev and Sokolov for interaction of classical relativistic electrons in the field of a plane wave [5]. It is worth noting the work [6]. It is very important to point out, that attraction of classical electrons in the ...

The vertebrate musculoskeletal system is composed of skeletal levers powered by muscles. Effective mechanical advantage (EMA) and muscle properties influence organismal performance at various tasks. Anatomical mechanical advantage (AMA) is a proxy for EMA that facilitates the study of preserved specimens when many muscles or many species are of interest. AMA is the quotient of in-lever to out-l...

Continuing the analysis of fracture size effect in Part I, which was focused on the maximum force in vertical penetration of ice, Part II tackles the problem maximum force that can be applied by a moving ice plate on an obstacle presented by a fixed structure. Based on an asymptotic approach, approximate solutions for are obtained for the size effects of ice thickness, effective structure diame...

In recent decades, aging population of most advanced countries has increased sharply, and elderly health care has become economically a big social issue. One way to cope with this problem is to introduce various service robots such as an arm-wrestling robot proposed in the article into our daily lives, which are able to promote elderly health and to save elderly welfare cost. For successful exe...

The dynamical friction force experienced by a body moving at relativistic speed in a gaseous medium is examined. This force, which arises due to the gravitational interaction of the body with its own gravitationally-induced wake, is calculated for straight-line and circular motion, generalizing previous results by several authors. Possible applications to the study of extreme mass-ratio inspira...

A charge e, moving with the velocity v through a time-constant space-varying magnetic potential field A, experiences a force of motional induction given by F v A = − ⋅ ∇ e c a f. Although the magnetic field is zero, B = 0; this force acts on the electrons passing on the two sides of a long sole-noid to produce the phase shift difference observed in the Aharonov-Bohm effect. PACS 03.65 – Quantum...

A number of problems of dynamic deformation in the presence of moving contact surfaces are considered. A grid characteristic method using a two-dimensional irregular triangular grid and a hybrid scheme with 1-2 order of approximation is adapted. An algorithm for calculating the force of friction and the force of static friction is proposed. The numerical solution to wheel rolling and shear wave...
