The phenomenon of the thermoinduced jumps of the step domains length in imperfect magnetic films with perpendicular with anisotropy is studied. For describing of the strip domain transitions into other metastable states, the stochastic equation of its head movement is used. In this equation the spatial non-uniformities of the medium are modeled by the restricted random function, and thermal fluctuations by the Gaussian white noise. The dependences on the temperature and the bias field of the mean time of strip domain stay in a metastable state were calculated by the methods of the Markovian processes theory

In this paper, we describe a new method for image denoising. We analyze properties of the Multiwavelet coefficients of natural images. Also it suggests a method for computing the Multiwavelet transform using the 1st order approximation. This paper describes a simple and effective model for noise removal through suggesting a new technique for retrieving the image by allowing us to estimate it from the noisy image. The proposed algorithm depends on mixing both soft-thresholds with Mean filter and applying concurrently on noisy image by dividing into blocks of equal size (for concurrent processed to increase the performance of the enhancement process and to decease the time that is needed for implementation by applying the proposed algorith

The navigational problem is an important and challenging problem in the field of robotics. The robots often find themselves in a situation where they must find a trajectory to another position in their environment, subject to constraints posed by obstacles and the capabilities of the robot itself. On-line navigation is a set of algorithms that plans and executes a trajectory at the same time. The system adopted in this research searches for a robot collision-free trajectory in a dynamic environment in which obstacles can move while the robot was moving toward the target. So, the ro
