inverse problem is one of the most important problems in geophysics as model parameters can be estimated from the measured data directly using inverse techniques. in this paper, applying different inverse methods on integration of s-wave and gpr velocities are investigated for estimation of porosity and water saturation. a combination of linear and nonlinear inverse problems are solved. linear ...

در این پایان نامه مباحثی در مورد نیم گروه های معکوس توپولوژیکی اولیه (مطلقا) h-بسته و فشرده (شمارایی) بدست می آوریم و ساختار نیم گروه های معکوس توپولوژی فشرده شمارایی و نیم گروه های معکوس توپولوژی همنهشت-آزاد را توصیف می کنیم و نشان می دهیم که نیم گروه دو دوری نمی تواند در نیم گروه معکوس توپولوژی فشرده شمارایی نشانده شود. we present some discussions about compact (countably) and (absolutely) h...

Efficient codes have been used effectively in both computer science and neuroscience to better understand the information processing in visual and auditory encoding and discrimination tasks. In this paper, we explore the use of efficient codes for representing information relevant to human movements during locomotion. Specifically, we apply motion capture data to a physical model of the human s...

In this paper we generalize the iterated refinement method, introduced by the authors in a recent work, to a time-continuous inverse scale-space formulation. The iterated refinement procedure yields a sequence of convex variational problems, evolving toward the noisy image. The inverse scale space method arises as a limit for a penalization parameter tending to zero, while the number of iterati...
