As the normal particle filter has an expensive computation and degeneracy problem, a propagation-prediction particle filter is proposed. In this scheme, particles after transfer are propagated under the distribution of state noise, and then the produced filial particles are used to predict the corresponding parent particle referring to measurement, in which step the newest measure information i...

Abstract Aiming at GPS dynamic filtering method, this paper uses the method of multi-scale analysis, combines the “current” statistical model of automotive carrier with multi-scale signal transformation which is based on statistical characteristic, establishes the new algorithm of multi-scale data fusion for GPS dynamic filter combining with normal Kalman filter algorithm, at last achieves the ...

In this paper we define a new bi-adaptive mesh denoising algorithm for efficient features preserving restoration of noisy models acquired from 3D scanners. The new filter is based on two recently introduced adaptive algorithms for triangle mesh denoising which show good results over previous methods. We adapt the MMSE filter noise threshold adaptive equation to compute new triangles normal vect...

Abstract: In this paper the author have designed and implemented an Extended Kalman filter (EKF) on the simulated model of the three-phase induction motor. An extensive simulation study has been carried out to asses the performances of the filter under various machine operating conditions and model uncertainties. In this work, it has been shown that the performance of EKF is found to be better ...

A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...

Simultaneous psychophysical tuning curves were obtained from normal-hearing and hearing-impaired listeners, using probe tones that were either at similar sound pressure levels or at similar sensation levels for the two types of listeners. Tuning curves from the hearing-impaired listeners were flat, erratic, broad, and/or inverted, depending upon the frequency region of the probe tone and the fr...

Although Covid-19 caused by the SARS-COV-2 virus, is a deadliest disease, many people experienced mild symptoms and were recovered soon. In this paper, coronavirus can be easily detected using CT scan images of affected patients. Initially, are pre-processed filters like Median filter Noise adaptive fuzzy switching median filter, then quality measurements MSE, PSNR calculated. After preprocessi...

odor emission is a common environmental problem in septic tank. the feasibility of using trickling filter to eliminate the malodorous gases from the septic tank was studied. a trickling filter is set up at the outlet of the waste gases of the septic tank, which was attached to the university's cafeteria. in this investigation, the trickling filter system was used, measuring the hydrogen sulfide...
