Particle filters are important approximation methods for solving probabilistic optimal filtering problems on nonlinear non-Gaussian dynamical systems. In this paper, we derive novel moment conditions for importance weights of sequential Monte Carlo based particle filters, which ensure the L convergence of particle filter approximations of unbounded test functions. This paper extends the particl...

Abstract-This paper presents a comprehensive simulation study of PI Controlled Three phase Series active power filter to improve power quality. The series active power filter employs a method for the reference compensation current based on Fast Fourier Transform Passive, L-C filters have disadvantage of fixed compensation and not fit for fast varying condition while by using auto tuned active p...

Discrete coefficients filter banks reduce the computational complexity for subband image coding system. A new time domain formulation is proposed for the design of near-perfect reconstruction filter banks with discrete coefficients. It can be shown that the proposed design method yields l 2 optimal solution which is considered to be practical in image coding applications. In addition, special e...

This paper presents two techniques for the design of digital filters with wordlength-constrained coefficients, the bit-flipping algorithm improved since it was first presented in [l] and the Downhill Simplex Method [2] modified to deliver fixed-point filter coefficients. Both techniques can be applied to design of filter coefficients from scratch or to the optimisation of their floatingpoint ve...

This paper provides a detailed analysis of how anisotropic diffusion filters work on seismic data. The conventional trace mixing filter is shown to be an implementation of a specific d i ffusion process. Diffusion filters have diff e rent forms, ranging from the simplest linear isotropic (L-I) diffusion to the most complex nonlinear anisotropic (NL-AI) diffusion. The NL-AI diffusion filter can ...

We propose a new nonmonotone filter method to promote global and fast local convergence for sequential quadratic programming algorithms. Our method uses two filters: a global gfilter for global convergence, and a local nonmonotone l-filter that allows us to establish fast local convergence. We show how to switch between the two filters efficiently, and we prove global and superlinear local conv...

A (distributive) p-algebra is an algebra 〈L;∨,∧, ∗, 0, 1〉 whose reduct 〈L;∨,∧, 0, 1〉 is a bounded (distributive) lattice and whose unary operation ∗ is characterized by x ≤ a if and only if a ∧ x = 0. If L is a p-algebra, B(L) = { x ∈ L : x = x } and D(L) = { x ∈ L : x = 1 } then 〈B(L);∪,∧, 0, 1〉 is a Boolean algebra when a ∪ b is defined to be (a∗ ∧ b∗)∗, for any a, b ∈ B(L), D∗(L) = { x ∨ x∗ ...
