A Pan-Sharpening Based on the Non-Subsampled Contourlet Transform Application to Worldview-2 Imagery Abstract?A Pan-Sharpening Based on the Non-Subsampled Contourlet Transform Application to Worldview-2 Imagery. Two pan-sharpening methods based on the non-subsampled contourlet transform (NSCT) are proposed. NSCT is very efficient in representing the directional information and capturing intrinsic geometrical structures of the objects. It has…
A Parallel Edge Preserving Algorithm for Salt and Pepper Image Denoising Abstract? A Parallel Edge Preserving Algorithm for Salt and Pepper Image Denoising. In this paper a two-phase filter for removing ?salt and pepper? noise is proposed. In the first phase, an adaptive median filter is used to identify the set of the noisy pixels;…
A Pareto-based Genetic Algorithm for Optimized Assignment of VM Requests on a Cloud Brokering Environment Abstract– In the first place, deal with cloud brokering for the assignment optimization of VM requests in three-tier cloud infrastructures. We investigate the Pareto-based meta-heuristic approach to take into account multiple client and broker centric optimization criteria. We propose a…
A Performance Investigation of a Four-Switch Three-Phase Inverter-Fed IM Drives at Low Speeds Using Fuzzy Logic and PI Controllers Abstract? A speed controller using a fuzzy-logic controller (FLC) for indirect field oriented control(IFOC) of induction motor (IM) drives fed by a four-switch three-phase (FSTP) inverter. In the proposed approach, the IM drive system is fed…
Investigation of a Switch Power Electronic Projects – iShuffle: Improving Hadoop Performance with Shuffle-on-Write Abstract– This paper presents a speed controller using a fuzzylogic controller (FLC) for indirect field-oriented control (IFOC) of induction motor (IM) drives fed by a four-switch three-phase (FSTP) inverter. In the proposed approach, the IM drive system is fed by an…
A Personalized Web Search Based on User Profile and User Clicks Abstract? A Personalized Web Search Based on User Profile and User Clicks. Generally web search engines are built to serve all users, independent of the individual needs of any user. Personalization of web search is to carry out retrieval for each user incorporating their…
A Power-Efficient Reconfigurable Output-Capacitor-Less Low-Drop-Out Regulator for Low-Power Analog Sensing Front-End Abstract-A power efficient reconfigurable output-capacitorless (OCL) low-drop-out (LDO) voltage regulator for low-power analog sensing front-end is proposed in this paper. This LDO consists of a floating-gate nMOS pass transistor, an adaptively biased error amplifier, and capacitive circuits for voltage reference generation and for feedback…
A Power-Efficient Signal-Specific ADC for Sensor-Interface Applications Abstract– A novel signal-specific power-efficient analog-to-digital converter (ADC) is proposed for sensorinterface applications. Instead of digitizing each analog sample independently, the proposed ADC determines the digital code corresponding to each new input sample by digitizing the difference of two consecutive samples. Therefore, for the applications with low-varying input…
A Pre-Authentication Approach to Proxy Re-encryption in Big Data Context Abstract-In the first place,Big Data growing amount of data, the demand of big data storage significantly increases. Through the cloud center, data providers can conveniently share data stored in the center with others. However, one practically important problem in big data storage is privacy Cloud…
A Precoding-Based Multicarrier Non-Orthogonal Multiple Access Scheme for 5G Cellular Networks Abstract-Non-orthogonal multiple access (NOMA) has become one of the desirable schemes for the 5G cellular network standard due to its better cell coverage capability, higher data rate, and massive connectivity. Orthogonal frequency division multiplexing (OFDM) can be combined with NOMA to get the higher…
A Precoding-based PAPR Reduction Technique for UF-OFDM and Filtered-OFDM Modulations in 5G Systems Abstract-In the first place, the universal filtered-orthogonal frequency division multiplexing (UF-OFDM) (also called universal filtered multicarrier (UFMC)) and the filtered-OFDM (F-OFDM) are candidates to be alternative to the OFDM modulation in the upcoming 5G systems thanks to their improved spectral occupation and…
A Predictive Cross-Layered Interference Management in a Multichannel MAC with Reactive Routing in VANET Abstract? Vehicular ad hoc networks (VANETs) represent a particular mobile technology that permits communication between vehicles, offering security and comfort. Nowadays, distributed mobile wireless computing is becoming a very important communication paradigm, due to its flexibility to adapt to different mobile…
