In this paper, the two dimensional (2-D) frequency sampling fllter system function described in reference [1] is further developed for frequency sampling filters that have linear phase and frequency sampling fllters that have linear phase and fourfold symmetry. Theresulting system functions are computationally more efficient for implementing frequency sampling filters with linear phase and freq...

Collection of appropriate qualitative and quantitative data is necessary for proper management and planning. Used the suitable inventory methods is necessary and accuracy of sampling methods dependent the inventory net and number of sample point. Nearest neighbor sampling method is a one of distance methods and calculated by three equations (Byth and Riple, 1980; Cotam and Curtis, 1956 and Cota...

Systems undergoing ®rst-order phase transitions are accompanied by free energy barriers which separate the free energy minima characterizing the co-existing phases. These barriers grows with increasing system size. With conventional Monte Carlo simulation methods the characteristic time for crossing the barriers grows exponentially with system size and the system will necessarily get trapped in...

We introduce an extension to the weighted ensemble (WE) path sampling method to restrict sampling to a one-dimensional path through a high dimensional phase space. Our method, which is based on the finite-temperature string method, permits efficient sampling of both equilibrium and non-equilibrium systems. Sampling obtained from the WE method guides the adaptive refinement of a Voronoi tessella...
