A humongous development in the study of Nyquist filter has been observed in the recent years. This paper presents a review of the work done on a Nyquist filter in the last decade. Nyquist filter is called M th band filter because it has zero coeffient at every M th sample except its middle coefficient. Different filter methods have been proposed with the focus of improving filter parameters lik...

This paper presents a comparative analysis between two current control strategies, constant source power and generalized Fryze current, used in Active Power Filter (APF) applications having three different modulation methods. The Hysteresis Band (HB) and first-order Delta-Sigma Modulation (DSM) as well as the second-order DSM is applied. The power section of the active power filter is viewed as...

Efficient representation of visual information lies at the foundation of many image processing tasks, including compression, filtering, and feature extraction. Efficiency of a representation refers to the ability to capture significant information of an object of interest in a small description. For practical applications, this representation has to be realized by structured transforms and fast...

Filter cake is one of the main waste products of zinc processing industries and it contains a high amount of toxic heavy metals. In this research in order to reduce heavy metals leachability in filter cake, Portland cement, natural pozzolan, diammonium phosphate (DAP), triple superphosphate (TSP), lime, zinc oxide and ground granulated blast furnace slag (GGBFS) have been used. This research’s ...

Information about the opponent is essential to improve automated negotiation strategies for bilateral multi-issue negotiation. In this paper we propose a negotiation strategy that combines a Bayesian technique to learn the preferences of an opponent during bidding and a Tit-for-Tat-like strategy to avoid exploitation by the opponent. The learned opponent model is used to achieve two important g...

The efficiencies of firms should be evaluated, based on their historical financial data. Here a process for evaluation is proposed. Each historical data set is reduced to a distribution function with a mean and a variance estimated by Kalman filter. Then, a stochastic efficiency model is applied to this reduced data. Then a new efficiency measure is proposed and compared with existing measures....

This paper describes an experimental study on the extent of capture efficiency in a fluidized bed system under controlled conditions. Using aerosols as tracer compound, the capture efficiency in a fluidized bed was quantitatively measured as a function of contact distance (time). The paper presents the experimental technique as well as the results relating the capture efficiency to the bed hydr...

A new scheme for the implementation of programmable FIR digital filters with 100% operational efficiency is presented in this paper. The term 100% operational efficiency implies that no zero bits have to be inserted between successive in−put data words in order the filter input to be synchronized with the filter output. Both the input data and the filter out−put are in two’s complement LSB−firs...
