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. […]
In this paper, voltage sag is compensated by the DVR (Dynamic Voltage Restorer) in distribution systems. This device is applied between the sensitive load and the supply in order to inject voltage in series to correct the voltage sag. Subsequently, all the other various DVR compensation techniques in the distribution system are explained. Due to […]
In this paper, we propose a wavelet based watermarking system. The system use wavelet transform for red, green and blues channel independently. We use space-time coding for encoding the watermark message before data embedding. The bit-error-rate of recovered message is calculated. The embedding factor is selected in such a way that the host video maintains […]
One of the main focus areas in human body reconstruction is the regeneration of bone tissue in different body zones by using various reconstruction applications. In the last two decades, different efforts have been undertaken for developing new bone reconstruction methods, and supporting techniques for stimulating bone healing mechanisms. It has been shown that during […]
In this article, the design procedure of a low latency Booth multiplier has been proposed. With the help of a novel 4-2 compressor, a high-performance 16×16 bit Booth multiplier has been implemented, which depicts high operating frequency. To achieve this, the proposed 4-2 compressor has been utilized successively in the Partial Product Reduction Tree (PPRT) […]
Due to the high amounts of sugarcane residue or bagasse which was produced by sugarcane plants in Iran, this study was aimed to optimize power generation from bagasse biomass in sugarcane plants using Particle Swarm Optimization (PSO) algorithm by data obtained from several case studies which had been simulated with SQP (Sequential quadratic programming) algorithm. […]
Penetration of distributed generation resources including wind power and solar photovoltaic units in distribution system has been increased, and it is important to examine their impact on the distribution systems’ operation in term of reliability. In this paper, the multi-objective dynamic feeder reconfiguration is introduced as an efficient approach for providing an energy management schedule […]
Nowadays, power systems should be operated in the highest level of utilization and near their stability limits because of economic reasons. So stability assessment of the power system to determine the stability limits has been always considered. In SCADA/EMS systems a constant value called security margin and steady-state stability limit are used to determine transient […]
In this paper, a novel lossless snubber is introduced that provides ZVS conditions for both On and Off instant of converter switches. On one hand, the energy of the snubber is optimally transmitted to the output so that no significant losses are imposed on the converter. Since the converter diodes are switched off as ZCS, […]
Hundreds of millions of homes worldwide already Have Fiber to The Home (FTTH) broadband connections since this technology holds many advantages over current technologies. The need for higher bandwidth by customers persists the network providers to upgrade their networks. The FTTH is the use of fiber optic cords to deliver communications signals from an operator’s […]
