Conventional arterial-line filters commonly use a large volume circular shaped housing, a wetted micropore screen, and a purge port to trap, separate, and remove gas bubbles from extracorporeal blood flow. Focusing on the bubble trapping function, this work attempts to explore how the filter housing shape and its resulting blood flow path affect the clinical application of arterial-line filters...

This paper aims at successful tracking of beach volleyball athletes during competition using only a single camera. Due to the wide range of possible motions and non-rigid shape changes, the tracking task becomes quite complex. We propose a novel method based on integral histograms, to use a high dimensional model for a particle filter without drastic increase in runtime. We extend integral hist...

This paper presents design of a defected ground structure coupled miniaturized dual-mode bandpass filter realized using a square patch. Two slots orthogonal to each other are cut on the patch to increase the path length of the fundamental mode while keeping the second mode current path almost unaffected. An inclined aperture cut on the ground plane right beneath the center of the patch is used ...

A Kalman-filter method for power control is proposed for broadband, packet-switched TDMA wireless networks. By exploiting the temporal correlation of co-channel interference, a Kalman filter is used to predict future interference power. Based on the predicted interference and estimated path gain between the transmitter and receiver, transmission power is determined to achieve a desired signal-t...

This paper presents a low-cost and highperformance programmable digital finite impulse response (FIR) filter. The architecture employs the computation sharing algorithm to reduce the computation complexity. In the traditional computation sharing algorithm, critical path constraint on the output summation stage is a bottleneck, thus, the canonic-sign-digit representation is utilized for filter c...

One case is the problem of acoustic echo cancellation, where the digital filter employed has to identify as close as possible the acoustic echo path that is found to be highly nonlinear. In this situation a better system identification can be achieved by a nonlinear filter. The problem is to find a nonlinear filter structure able to realize a good approximation of the echo path without any sign...

This paper introduces the Path Relinking Particle Filter (PRPF) algorithm for improving estimation problems in human motion capture. PRPF hybridizes both Particle Filter and Path Relinking frameworks. The proposed algorithm increases the performance of general Particle Filter by improving the quality of the estimate, adapting computational load to problem constraints and reducing the number of ...
