This article proposes a cascade proportional-integral second-order sliding mode control (PI-SMC) method for matrix converter-fed brushless doubly fed induction machine (BDFIM). The PI-SMC consists of PI speed controller with an inner-loop (SMC). provides reference to the SMC constraints according system requirements in terms maximum current and speed. As discontinuous sign function traditional ...

Aim: Both hepatitis B virus (HBV) and hepatitis C virus (HCV) replicate in the liver and show resistance against innate immunity and interferon (IFN) treatment. Whether 45 there is interference between these two viruses is still controversial. We investigated the interference between these two viruses and the mode of resistance against IFN. Methods: We performed infection experiments of either ...

As a result of investigation of interference into FM systems, a new algorithm for the process of demodulation is proposed. When compared to the method using the conventional limiterdiscriminator, it offers better immunity against the baseband interference noise. Desired signal processing is performed by the functional devices added to the conventional limiter-discriminator in such a way that th...

Wavelet Packets (WPs), multiuser detection, diversity and suppression filters are very effective in reducing the interferences in Coded Division multiple access communication (CDMA) systems. In this paper, we analyzed a WP Multi-Carrier (MC)-CDMA system that employs decorrelating multiuser detector. This type of detector, supports a higher number of users, suppresses the multiple access interfe...

The prevalence of pacemaker patients among the general population and of conducted energy devices (CED) for law enforcement and self-defence is increasing. Consequently, the question whether cardiac pacemaker (CPM) patients are on particular risk becomes increasingly important. The risk of Taser X26 electric interference with implanted CPM has been investigated by numerical simulation at MRI-ba...

The radiated immunity of passenger cars and commercial vehicles is validated using electromagnetic interference from off-vehicle radiation sources in an anechoic chamber according to the procedure ISO 11451-2. Common electrical or electronic vehicle systems, including dual flash, monitors, entertainment must be a standardized evaluation procedure. However, Automated Driver Assistance System (AD...

The processes of intelligent data processing in computer vision systems have been researched. problem structural image recognition is relevant. This a promising way to assess the degree similarity objects. approach provides simplicity construction and high reliability decision making. main an effective description characteristic features distortion fragments analyzed reasons for changing input ...

This paper presents the conducted assessment of noise immunity request signal transmission channel and response for flight information secondary radar systems as part aircraft responders. The considered system is an open single-channel queuing with refusing due to action in intentional unintentional correlated uncorrelated (intra-system) interference ground-based receivers that receive, process...

Antiviral immunity in insects and plants is mediated by the RNA interference (RNAi) pathway in which viral long double-stranded RNA (dsRNA) is processed into small interfering RNAs (siRNAs) by Dicer enzymes. Although this pathway is evolutionarily conserved, its involvement in antiviral defense in mammals is the subject of debate. In vertebrates, recognition of viral RNA induces a sophisticated...

The paper presents an overview of the works devoted to video compression algorithms based on artificial intelligence methods. Two main directions for development such are identified - these modules post-processing results work classical and that completely replace existing codecs. problems performance evaluation criteria considered. It was found calculation standard deviation, as PSNR, cannot b...
