Numerical Modelling of the Segmental Lining of Underground Structures
There are several methods for analysing the behaviour of underground structures under different loading conditions. Most of these methods have many simplifications; therefore, in some cases, the results are too conservative and a very high safety factor, usually of more than 2 is needed. On the other hand, for stability analysis and the designing of support systems, these methods consider segme...
متن کاملthe algorithm for solving the inverse numerical range problem
برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.

متن کاملNumerical modelling of induced rip currents by discontinuous submerged breakwaters
Submerged breakwaters are one of the shore protective structures. Any discontinuity in these breakwaters causes changes on current parameters including speed and water surface profile. In this paper, discontinuous submerged breakwaters were modelled to investigate the changes in the wave and flow pattern.To investigate the phenomenon, three models including a shore with constant slope, a shore ...
متن کاملIntracavity pumped OPO Interferometry
In this paper I present an overview of optical parametric oscillator-the basic mechanism and several advantages of it. One application of using OPO as a differential interferometer is explained in detail. The basic mechanism of OPO OPO is short for optical parametric oscillator, which consists essentially of an optical resonator and a nonlinear optical crystal. It is driven by a pump beam and g...
