Fractional pel motion compensation generally improves coding efficiency due to more precise motion accuracy and low path filtering effect in generating image at fractional pel positions. In H.264, quarter pel motion compensation is applied, where image at half pel position is generated by 6 tap Wiener filter. And the adaptive interpolation filter technique, which adaptively changes filter chara...

In Digital Signal Processing FIR Filter is used to remove the noise or unwanted components from a signal. This paper Presents an efficient VLSI Architecture of a Multi-Standard Digital Up Converter (DUC) based FIR filter that is used to remove the noise in the received channel data bits effectively. The proposed DUC based FIR filter consists of weight update block with Shift add architecture to...

Several approaches have been introduced in literature for active noise control (ANC) systems. Since FxLMS algorithm appears to be the best choice as a controller filter, researchers tend to improve performance of ANC systems by enhancing and modifying this algorithm. In this paper, the existing FxLMS algorithm is modified which provides a new structure for improving the noise reduction and conv...

objective: this study aimed to investigate the mediating role of maladaptive schemas between childhood emotional maltreatment and psychological distress among college students. methods: this was a descriptive-correlative and after the fact study. a total of 315 students were selected with multistage cluster sampling from students of tehran universities. the participants completed the lifetime o...

Quagga is a software routing suite which provides implementations of various routing protocols for UNIX based platforms. It supports implementations of RIP, OSPF and BGP version 4. Path-exploration damping is one possible approach to filter out the path hunting phenomenon in BGP, in which a single prefix withdrawal event at the original announcement’s origin may generate a large volume of subse...

In Active noise control (ANC), the secondary path has usually a time varying behavior. For these cases, an online secondary path modeling method that uses a auxiliary noise as a training signal is required to ensure convergence of the system. The modeling accuracy and the convergence rate are increased when a auxiliary noise with a larger variance is used. A sudden change in the secondary path ...

In this paper, a novel Bayesian image restoration method based on a combination of priors is presented. It is well known that the Total Variation (TV) image prior preserves edge structures while imposing smoothness on the solutions. However, it tends to oversmooth textured areas. To alleviate this problem we propose to combine the TV and the Poisson Singular Integral (PSI) models, which, as we ...
