this paper presents simplified hydrodynamics model for a biomimetic robot fish based on quantitative morphological and kinematic parameters of crangiform fish. the motion of four pangasius sanitwongsei with different length and swimming speed were recorded by the digital particle image velocimetry (dpiv) and image processing methods and optimal coefficients of the motion equations and appropria...
In this paper, the equation of motion for an incompressible transversely isotropic fibre-reinforced elastic solid is derived in terms of a scalar function. The general solution of the equation of motion is obtained, which satisfies the required radiation condition. The appropriate traction free boundary conditions are also satisfied by the solution to obtain the required secular equation for...

برخلاف ربات هایی که پایه آنها متصل به زمین است، پایه ربات های معلق اصولا تماسی با زمین ندارد. که این مسیله به خودی خود سبب افزونگی درجات آزادی (البته از نظر سینماتیکی) آنها می شود. هر چند که این افزونگی، به عنوان یک مزیت مهم، سبب می شود که فضای گازی ربات افزایش یابد و یا ربات توانایی انجام چندین خواسته را داشته باشد، ولی کنترل این دسته از ربات ها را سخت تر و پیچیده تر می کند. در این پایان نامه ...
In this paper, a comparison is made between direct and indirect perturbation approaches to solve the non-linear vibration equations of a piezoelectrically actuated cantilever microbeam. In this comparison, the equation of motion is considered according to Euler-Bernoulli theory with considering the non-linear geometric and inertia terms resulted from shortening effect. In the direct perturbatio...
air-jet weaving is an advanced weaving method with high efficiency and productivity. it is one of the most widely used methods of weaving in the world. in air-jet filling insertion, the motion of weft yarn is caused by friction between weft yarn and air blown through nozzle. after declamping and subjecting the yarn to air stream, its motion is not active but very complicated and influenced by s...
in this paper we obtain exact solutions of the generalized kuramoto-sivashinsky equation, which describes manyphysical processes in motion of turbulence and other unstable process systems. the methods used to determine the exact solutions of the underlying equation are the lie group analysis and the simplest equation method. the solutions obtained are then plotted.
