This paper introduces a new type of CMOS-based current conveyor: current controlled fully balanced second generation current conveyor (CFBCCII) element which has a pair of differential Y terminals, a pair of differential X terminals and two pairs of Z terminals. The proposed circuit offers electronic tuning possibilities by means of a current adjustable intrinsic resistance at its X terminal. A...

We present a technique to implement three-dimensional (3-D) object recognition based on phase-shift digital holography. We use a nonlinear composite correlation filter to achieve distortion tolerance. We take advantage of the properties of holograms to make the composite filter by using one single hologram. Experiments are presented to illustrate the recognition of a 3-D object in the presence ...

In this paper we present two time invariant models mobile position tracking in three dimensions, which describe the movement in x-axis, y-axis and z-axis simultaneously or separately, provided that there exist measurements for the three axes. We present the time invariant filters as well as the steady state filters: the classical Kalman Filter and Lainiotis Filter and the Join Kalman Lainiotis ...

A filter F on a group G is a T -filter if there is a Hausdorff group topology τ on G such that F τ −→ 0. This notion can be specialized for sequences, in which case we say that {an} is a T -sequence. In this paper, T -filters and T -sequences are studied. We characterize T -filters in non-abelian groups, show that certain filters can be interpreted as topological extensions of the notion of ker...

slow sand filters are as a proper technology for pre-treatment of raw water, with a fine and medium trubidity in small communities in developing countries. thus, with a minimum operation cost and minimum need for expest bodies have the maximum efficiency. the purpose of this research is carried out to evaluate the efficiency of two processes of horizontal flow roughing filter and vertical flow ...

In this paper, the results of both normal-hearing, and profoundly hearing-impaired adults, tested with spectrum compressed speech via the modified chirp-z algorithm, with and without visual stimuli, are reported. Ten normal-hearing adult listeners and three profoundly hearingimpaired adult listeners were asked to identify nonsense syllables presented auditorily and bimodally (audition and visio...

Received Nov 13,2012 Revised Jan 05, 2013 Accepted Jan 12,2013 In this paper, we have proposed a framework to count the moving person in the video automatically in a very dense crowd situation. Median filter is used to segment the foreground from the background and blob analysis is done to count the people in the current frame. Optimization of different parameters is done by using genetic algor...

Radio Frequency Interferences (RFI), such as strong Continuous Wave (CWI), can influence the Quality of Service (QoS) communications, increasing Bit Error Rate (BER) and decreasing Signal-to-Noise Ratio (SNR) in any wireless transmission, including a Digital Video Broadcasting (DVB-S2) receiver. Therefore, this paper presents an algorithm for detecting mitigating Multi-tone Interference (MCWI) ...
