The DASH (Doppler Asymmetric Spatial Heterodyne) is used to detect the upper atmospheric wind velocity by its imaging Fizeau interference fringes. There are two measurement methods: Fourier series method (FSM) and popular transform (FTM). However, accuracy of FTM greatly influenced window function, calculation amount relatively complicated. Four-point algorithm (FPA) for DASH’ s proposed in thi...

In this paper, buckling behavior of moderately thick functionally graded rectangular plates resting on elastic foundation subjected to linearly varying in-plane loading is investigated. The neutral surface position for a functionally graded plate which its material properties vary in the thickness direction is determined. Based on the first-order shear deformation plate theory and the neutral s...

− A number of Functional Size Measurement (FSM) methods have been proposed in the literature, but so far there has been no systematic evaluation of these methods. A major criticism is that little attention has been paid to the empirical validation of FSM methods. By empirical validation we refer to the evaluation of the efficacy of the method and its likely adoption in practice using experiment...

Partitioning has been shown to be an effective method for synthesis of low power finite state machines. In this approach, an FSM is partitioned into two or more coupled sub-machines such that most of the time only one of the sub-machines is active. In this paper, we present a GA based approach for simultaneous partitioning and state assignment of finite state machines with power reduction as th...

In this work, we study the convergence of an efficient iterative method, the fast sweeping method (FSM), for numerically solving static convex Hamilton–Jacobi equations. First, we show the convergence of the FSM on arbitrary meshes. Then we illustrate that the combination of a contraction property of monotone upwind schemes with proper orderings can provide fast convergence for iterative method...

one of the serious problems of iran’s watersheds is soil erosion and can be considered as one of the main obstacles to achieve sustainable agricultural development and natural resources. in most countries of the world, because of absence of accurate data for the sediment erosion, deposition utilizing models to estimate erosion is inevitable. in order to apply effective management in natural res...

We consider elastic waves in materials with cylindrical orthotropy, this being a plausible model for wood. For time-harmonic motions, the problem is reduced to some coupled ordinary differential equations. Previously, these have been solved using the method of Frobenius (power-series expansions). We use Neumann series (expansions in Bessel functions of various orders), motivated by the known cl...

ABS’I’RA(’.T. In this paper, we study initial value problems for couph’d second order delay" differcntial equations with variable coefficients. By means of the application of the method of st,ps al the method of Frobenius, the exact solution of the problem is constrcted. Then, in a toain, a fitite analytic solution with error bounds is provided. C, iven an admissible error t, we give the number...

In this paper we introduce concepts of a potential fault latency and a real fault latency for Finite State Machines (FSMs). The potential latency defines a minimal value of the possible latency for an FSM, while the real latency relates to the certain implementation of the FSM. A method for investigation of latencies for online checking FSMs is described. This technique is based on selection of...
