Ship Detection From Optical Satellite Images Based on Saliency Segmentation and Structure-LBP Feature Abstract-In the first place, automatic ship detection from optical satellite imagery is a challenging task due to cluttered scenes and variability in ship sizes. In the same way, a detection algorithm based on saliency segmentation and the local binary pattern (LBP) descriptor…
Similarity Based Rating Prediction For Cold Start User In Recommendation System Abstract-A recommender system (RS) aims to provide personalized recommendations to users for specific items (e.g., music, books). Popular techniques involve content-based (CB) models and collaborative filtering (CF) approaches. In this paper, we deal with a very important problem in RSs: The cold start problem….
Similarity Group-by Operators for Multi-Dimensional Relational Data Abstract?Abstract The SQL group-by operator plays an important role in summarizing and aggregating large datasets in a data analytics stack. While the standard group-by operator, which is based on equality, is useful in several applications, allowing similarity aware grouping provides a more realistic view on real-world data that…
Simple T wave metrics may better predict early is schema as compared to ST segment Abstract?Abstract Recently, security issues are obstructing the development and using of cloud computing services. Authentication plays an important role in the cloud security, and numerous concerns have been raised to prevent an unauthorized users to access the entities? resources (sender…
Simulation Modelling Practice and Theory Abstract?Abstract The inverted pendulum problem is one of the most important problems in control theory and has been studied excessively in control literatures. When a control system have more than two PID controllers, the adjustment of PID parameters is not an easy problem. In this paper, PID controllers are applied…
Simultaneous Sensing and Transmission for Cognitive Radios With Imperfect Signal Cancellation Abstract-In conventional cognitive radio systems, the secondary user employs a ?listen-before-talk? paradigm, where it senses if the primary user is active or idle, before it decide to access the licensed spectrum. However, this method faces challenges, with the most important one being the reduction…
Single Bit-Line 7T SRAM Cell for Near-Threshold Voltage Operation With Enhanced Performance and Energy in 14 nm FinFET Technology Abstract?Although near-threshold voltage (NTV) operation is an attractive means of achieving high energy efficiency, it can degrade the circuit stability of static random access memory (SRAM) cells. < final year projects > [numbers_sections number=”1″ title=”Including =Packages=”…
Single-Ended Schmitt-Trigger-Based Robust Low-Power SRAM Cell Abstract? a Schmitt-trigger-based single-ended 11T SRAM cell, which significantly improves read and write static noise margin (SNM) and consumes low power. Simulation results show that the cell also achieves the lowest leakage power dissipation among the cells considered for comparison. We also investigate the impact of process, voltage, and…
Stochastic Resource Provisioning for Container ized Multi-Tier Web Ser vices in Clouds Abstract-The increasing need for high-speed logic circuits is causing the conventional flip-flop (FF) designs to migrate to differential FF designs. With the small magnitude of input voltages (and the resulting small noise margins) needed for proper operation, sense-amplifier based FF designs (SAFF) are…
Online Allocation of Virtual Machines in a Distributed Cloud Abstract– This paper proposes a new single-phase inverter topology and describes the control method for the proposed inverter. The inverter consists of an energy buffer circuit, a dc-dc conversion circuit and an H-bridge circuit. The energy buffer circuit and H-bridge circuit enable the proposed inverter to…
Single-phase Microgrid with Dual Photovoltaic Array for Efficient Power Balance based on Power Conditioning System Abstract?Abstract This paper proposes a single-phase microgrid based on a power conditioning system with dual photovoltaic array and an energy storage. A grid-connected inverter and battery charger are adopted for energy conversion from the two arrays of different construction. The…
Single-Phase to Three-Phase Converters With Two Parallel Single-Phase Rectifiers and Reduced Switch Count Abstract? Two single-phase to three-phase conversion systems for a three-phase load application. The load is connected to a single-phase grid through an ac?dc?ac single-phase to three-phase converter. The single-phase rectifier is composed of two parallel single-phase half-bridge rectifiers. The first proposed topology…
