One of the fundamental structures of inverters with soft switching is the use of quasi-resonant DC link (QRDCL) circuits, in which element switching occurs in the zero voltage (ZVS) and / or zero current (ZCS) conditions and also the use of pulse width modulation (PWM). One of the indices of distinction and superiority of these […]
One of the most important problems in heart signal processing is the extraction of fetal electrocardiogram (FECG). One of the reasons that we are interested in FECG extraction is that this signal consists of important characteristics about healthy conditions of fetus. Based on available conditions, Blind Source Separation is a suitable method for this problem. […]
Surface electromyography (SEMG) from respiratory muscles is a non-invasive and effective method of studying neuromuscular diseases, muscle fatigue, enhancement of muscular function and also human-computer interface. This signal is contaminated by different noises. These include environmental noises like power line noise and also internal noises such as electrocardiographic noise. The clean EMG signal can be […]
Intrusion Detection System (IDS) deals with very large amount of data that includes redundant and irrelevant features. Therefore feature selection is a necessary data pre-processing step to design IDSs that are lightweight. In this paper, a novel feature selection method based on data mining techniques is proposed which uses fuzzy association rules to obtain the […]
In this article, a combined method is used to improving transient stability. In power systems, the maximum use of existing capacities along with the increased powers transferred through the transition lines make transient stability studies even more important. When the fault occurs, the kinetic energy of system is increased, and if the system kinetic energy […]
With the growing demands of home networking, the existing networking technologies couldn’t satisfy user expectations any more. Today networking technologies is interested that don’t need new cable and have high bandwidth. HomePNA (Home Phoneline Networking Alliance) is a solution.HomePNA3.0 and Ethernet was similar in MAC sublayer; hence, HomePNA3.0/Ethernet reconfigurable implementation was appeared cost-effective. But the […]
Autonomous vehicle present a several problems in the modern commercialized electric vehicle (EV). One of the weakest points of electric vehicles is the battery system, vehicle autonomous depend on the battery state of charge (SOC). In this paper novel strategy of EV power electronics studies based on direct torque space vector modulation technique in the […]
Electricity market plays an important role in improving the economics of electrical power system. Transmission network is vital entity in an open access restructured electricity market. Whenever transmission network congestion occurs in an electricity market, it divides the market in different zones and the trading price of electricity will no longer remains the same for […]
An important technique in image and video processing is global motion estimation (GME). The common GME methods can be classified in direct and indirect categories. Whereas the direct global motion estimation techniques boast reasonable precision they tend to suffer from high complexity. As with indirect methods, though presenting lower complexity they mostly exhibit lower accuracy […]
In this paper the transient stability of an electric power system is improved by fuzzy logic controlled superconducting magnetic energy storage (SMES). The effectiveness of the proposed fuzzy controlled SMES is compared with a conventional proportional integral (PI) controlled SMES. In addition to it a comparison between the fuzzy controlled SMES and fuzzy controlled braking […]
