one of the problems associated with adaptive fir filters in the identification of systems with long impulse responses, is their excessive computational complexity. recently a new kind of adaptive filters, based on three-level clipping of the input signal has been presented for reduction of their computational complexity. in this paper, a theoretical analysis of the steady-state misalignment of ...
Abstract Introduction: Nowadays, the greatest of process type used in treatment of beverage water is conventional treatment. That it cannot remove organic matter effectively. Filtration is one of the most important treatment processes used in water treatment plant.The one of approaches, modification of conventional rapid sand filters into dual or multimedia filters. Methods: This study wa...
introduction: the purpose of this study is to define the optimal parameters for the tomographic reconstruction procedure in a routine single photon emission tomography. the hoffman brain phantom is modified to evaluate the reconstruction method. the phantom was imaged in a 3 and 2-dimensional conformation and the results were compared. materials and methods: the 2d phant...
