All of the. foregoing indicates the importance of the X-ray diffraction study of liquids and adds. strong evidence in favor of the interpretation on the basis of a molecular space array. The existence of this array or cybotaxis is of fundamental interest in an understanding of physical phenomena in liquids. 1 Stewart and Morrow, Physic. Rev., 30, 9, 232 (1927). 2Adam, Proc. Roy. Soc., Alol, p. ...

In this work we attempt to show in a clear and simple manner the fundamental ideas of the Renormalization Theory. With that intention we use two well-known problems of the Physic and Engeneering undergraduate students, the calculation of the electrostatic and vector potential of a infinite line charge density and current, respectively. We still employ different regularization methods (cut-off, ...

The long liner position sensor is a kind of position sensor that can measure the distance between the detected point and the receiving point by calculating the duration of the excitation and the receipt of ultrasonic waves. In our experiment, the unsymmetrical phenomenon of elastic waves was detected under different initial condition with the symmetrical sensor system, due to the anisotropy of ...

this paper presents a class of theoretical and iterative method for linear partial differential equations. an algorithm and analytical solution with a initial condition is obtained using the reduced differential transform method. in this technique, the solution is calculated in the form of a series with easily computable components. there test modeling problems from mathematical mechanic, physi...

Homogenization method is applied to topology optimization of a weakly coupled two physics problem, where structures are made periodically perforated material. The microscopic periodic cell macroscopically modulated, the design characterized by material density and its homogenized Hooke’s law at each point domain. coupling weak because involved solved consecutively: first, fluid determined using...
