To provide enough power for modern cities as well as elegant appearance of urban city, the indoor substation has been widely constructed. But the poor ventilation problem of main transformer room also appears. Although the traditional calculation method of air supply volume of ventilator is easy to use, the factor of air surrounding the transformer is not under consideration. So in this paper, a computational...
Adhering only to logic consistency principle, this paper first makes a systematical logic examination and arrangement over the classical electromagnetism created by Maxwell, pointing out that Maxwell's equations cannot directly construct a proper boundary value problem and have many logic improprieties or inconsistency implied in the old theorem.
Bispinor is a differential operator endowed with objective connotation and lots of particular characters, and thus becomes a key and unavoidable concept in electromagnetic theory. This paper points out that it is impossible or even purely self-deceptive for us to suppose forms of gauges in order to replace bispinor with other mathematical forms. Based upon a rather systematic analysis of bispinor,...
Dexterous robotic arms have gained increasing attention in the robotics community in recent years, especially snake-like robots. A cable-driven snake-like robot arm (CDSLRA) owns a number of promising advantages such as: light-weight structure, low energy consumption, high speed motion due to low moment inertia and it is suitable to work in constrained work-conditions. A prototype consisting a series...
The ability of Vertical and/or Short Take-Off and Landing is the objective of advanced fighter and shipboard fighter. In this paper we proposed a prototype of tailless configured STOVL aerial vehicle. Based on which, the mathematical model was studied by mechanical analysis and CFD (Computing Fluid Dynamics) computation. Besides, an intelligent adaptive based control law was proposed and the optimization...
