A Highly Reliable and High Efficiency Quasi Single – Stage Buck – Boost Inveter Abstract? To regulate an output ac voltage in inverter systems having wide input dc voltage variation, a buck-boost power conditioning system is preferred. This paper proposes a novel high efficiency quasi single-stage single-phase buck-boost inverter. The proposed inverter can solve current…
Civil Registry (Android App) Abstract– To regulate an output ac voltage in inverter systems having wide input dc voltage variation, a buck-boost power conditioning system is preferred. This paper proposes a novel high efficiency quasi single-stage single-phase buck-boost inverter. The proposed inverter can solve current shoot-through problem and eliminate PWM dead-time, which leads to greatly…
A Hybrid Image Compression Scheme using DCT and Fractal Image Compression Abstract?A Hybrid Image Compression Scheme using DCT and Fractal Image Compression. We introduce a new way to use fractal coding for image compression, based on the parallel use of a fractal encoder and a DCT encoder. The two encoders are given the complementary roles…
A hybrid particle swarm optimization for feature subset selection byintegrating a novel local search strategy Abstract?tFeature selection has been widely used in data mining and machine learning tasks to make a modelwith a small number of features which improves the classifier?s accuracy. In this paper, a novel hybridfeature selection algorithm based on particle swarm optimization…
A Hybrid Wavelet Transform and Neural- Network-Based Approach for Modelling Dynamic Voltage-Current Characteristics of Electric Arc Furnace Abstract? A Hybrid Wavelet Transform and Neural- Network-Based Approach for Modelling Dynamic Voltage-Current Characteristics of Electric Arc Furnace. This paper proposes a discrete wavelet transform (DWT) and radial basis function neural network (RBFNN) based method for modeling the…
A Kernel Clustering Algorithm With Fuzzy Factor: Application to SAR Image Segmentation Abstract?A Kernel Clustering Algorithm With Fuzzy Factor: Application to SAR Image Segmentation. The presence of multiplicative noise in synthetic aperture radar (SAR) images makes segmentation and classification difficult to handle. Although a fuzzy C-means (FCM) algorithm and its variants (e.g., the FCM_S, the…
A Look-Ahead Clock Gating Based on Auto-Gated Flip-Flops Abstract?Clock gating is very useful for reducing the power consumed by digital systems. Three gating methods are known. The most popular is synthesis-based, deriving clock enabling signals based on the logic of the underlying system. It unfortunately leaves the majority of the clock pulses driving the flip-flops…
A Low Cost Speed Estimation Technique for Closed Loop Control of BLDC Motor Drive Abstract-At the first place, proposes a sensorless speed control technique for Brushless DC Motor (BLDC) drives by estimating speed from the hall sensor signals. Conventionally, the speed is measured using precision speed encoders. Since these encoders cost almost half of the…
A Low-Complexity Turbo Decoder Architecture forEnergy-Efficient Wireless Sensor Networks Abstract-A Low-Complexity Turbo Decoder Architecture forEnergy-Efficient Wireless Sensor Networks. Turbo codes have recently been considered for energy-constrained wireless communication applications, since they facilitate a low transmission energy consumption. However, in order to reduce the overall energy consumption, lookup table-log-BCJR (LUT-Log-BCJR) architectures having a low processing energy…
A Low-Complexity, Sequential Video Compression Scheme Using Frame Differential Directional Filter Bank Decomposition in CIE La? b ? Color Space Abstract– In the first place, proposes a novel differential directional filter bank (DFB) decomposition-based video coding scheme. DFB decomposition is generally preceded by Laplacian pyramid decomposition, as in contourlet transform, in order to separate the…
A Low-Latency and Low-Power Hybrid Scheme for On-Chip Networks Abstract?Network-on-chip (NoC) has emerged as a vital factor that determines the performance and power consumption of many-core systems. This paper proposes a hybrid scheme for NoCs, which aims at obtaining low latency and low power consumption. In the presented hybrid scheme, a novel switching mechanism, called…
A Low-Power Robust Easily Cascaded PentaMTJ-Based Combinational and Sequential Circuits Abstract?Advanced computing systems embed spintronic devices to improve the leakage performance of conventional CMOS systems. High speed, low power, and infinite endurance are important properties of magnetic tunnel junction (MTJ), a spintronic device, which assures its use in memories and logic circuits. < final year...
