Publish/subscribe middleware provides efficient support for loosely coupled communication in distributed systems. A number of different distributed message-filtering algorithms have been proposed. So far, a systematic comparison and analysis of these filter algorithms is still missing. This paper proposes a classification scheme for distributed filter algorithms that supports the theoretical an...

because of a lack of means to match the traditional operating rules and regulations with time dependent variant of water needs in the present irrigation networks, a considerable portion of available water is wasted in these systems. this makes research on methods of operation and determination of types of controls as well as optimization approaches, attainable through using hydrodynamic models ...

in this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twomechanisms s...

Speech quality and intelligibility might significantly deteriorate in the presence of background noise, especially when the speech signal is subject to subsequent processing. In particular, speech coders and automatic speech recognition (ASR) systems that were designed or trained to act on clean speech signals might be rendered useless in the presence of background noise. Speech enhancement alg...

In this paper, a mechanism is designed for integration of inertial navigation system information (INS) and global positioning system information (GPS). In this type of system a series of mathematical and filtering algorithms with Tightly Coupled techniques with several objectives such as application of integrated navigation algorithms, precise calculation of flying object position, speed and at...

In this paper, we give a cross-disciplinary survey on “population-based” Monte Carlo algorithms. These algorithms consist of a set of “walkers” or “particles” for the representation of a high-dimensional vector and the computation is carried out by a random walk and split/deletion of these objects. The algorithms are developed in various fields in physics and statistical sciences and called by ...

The key objective of this paper is to provide an idea for VLSI Implementation of RLS algorithm for noise cancellation with real time analog inputs. In this paper, we present an efficient architecture for the implementation of distributed arithmetic based multiplier less adaptive filter. The throughput rate of update and concurrent implementation of filtering and weightupdate operations. The con...

We address the recursive computation of the filtering probability density function (pdf) pnjn in a hidden Markov chain (HMC) model. We first observe that the classical path pn 1jn 1-pnjn 1-pnjn is not the only possible one that enables to compute pnjn recursively, and we explore the direct, prediction-based (P-based) and smoothingbased (S-based) recursive loops for computing pnjn. We next propo...

This paper presents a novel approach for designing a linear phase digital high pass FIR filter using Improved Particle Swarm Optimization (IPSO) algorithm. Design of FIR f ilter is a multi-modal optimization problem. The conservative gradient based optimization techniques are not efficient for digital filter design. Given the specifications for the filters to be realized, IPSO algorithm generat...
