A Multi-Hop Broadcast Protocol for Emergency Message Dissemination in Urban Vehicular Ad Hoc Networks Abstract?In vehicular ad hoc networks (VANETs), multi-hop wireless broadcast has been considered a promising technology to support safety-related applications that have strict quality-ofservice (QoS) requirements such as low latency, high reliability, scalability, etc. However, in the urban transportation environment, the efficiency…
A Multilevel Index Model to Expedite Web Service Discovery and Composition in Large-Scale Service Repositories Abstract? The number of Web services has grown drastically. Then how to manage them efficiently in a service repository is an important issue to address. Given a special field, there often exists an efficient data structure for a class of…
A New Cascaded Switched-Capacitor Multilevel Inverter Based on Improved Series?Parallel Conversion With Less Number of Components Abstract? The aim of this paper is to present a new structure for switched-capacitor multilevel inverters (SCMLIs) which can generate a great number of voltage levels with optimum number of components for both symmetric and asymmetric values of dc-voltage…
A new fusion model for classification of the lung diseases using genetic algorithm Abstract? Automatic classification of lung diseases in computed tomography (CT) images is an important diagnostic tool for computer-aided diagnosis system. In this study, we propose a new image based feature extraction technique for classification of lung CT images. A novel fusion based…
Hybrid Job-Driven Scheduling for Virtual MapReduce Clusters Abstract? Power electronics solutions based on multiple converter configurations offer cost-effective solutions by integrating a number of components at input or output power stages. A new multiinput isolated three-level converter for renew-able and sustainable energy systems adopting high dc link voltage. Multiple dc sources are integrated to the…
A Normal I/O Order Radix-2 FFT Architecture to Process Twin Data Streams for MIMO Abstract? Many applications require simultaneous computation of multiple independent fast Fourier transform (FFT) operations with their outputs in natural order. Therefore, this brief presents a novel pipelined FFT processor for the FFT computation of two independent data streams. The proposed architecture…
A Novel Approach for Denoising and Enhancement of Extremely Low-light Video Abstract? a novel approach for noise reduction and enhancement of extremely low-light video is proposed. For noise removal, a motion adaptive temporal filtering based on a Kalman structured updating is presented. Dynamic range of denoised video is increased by adjustment of RGB histograms using…
A Novel Approach for Efficient Usage of Intrusion Detection System in Mobile Ad Hoc Networks Abstract? Mobile Ad hoc Networks (MANET) are self-configuring, infrastructureless, dynamic wireless networks in which the nodes are resource constrained. Intrusion Detection Systems (IDS) are used in MANETs to monitor activities so as to detect any intrusion in the otherwise vulnerable…
A novel approach to generate MCQs from domain ontology: Considering DL semantics and open-world assumption Abstract? Ontologies are structures, used for knowledge representation, which model domain knowledge in the form of concepts, roles, instances and their relationships. This knowledge can be exploited by an assessment system in the form of multiple choice questions (MCQs). The…
A Novel Approach to Segment Skin Lesions in Dermoscopic Images Based on a Deformable Model Abstract? Dermoscopy is an imaging technique that has been widely used in the diagnosis of skin lesions. However, its accuracy largely depends on the dermatologist?s experience; thus, computer-aided diagnosis techniques are required. In this paper, a novel approach based on…
A Novel Clustering-Based Spectrum Sensing In Cognitive Radio Wireless Sensor Networks Abstract? A cognitive radio wireless sensor network (CR -WSN), where each sensor node is equipped with cognitive radio. A typical concern in CR-WSN is energy consumption due to resource-constrained nature of sensor nodes. Moreover, additional energy is consumed in a CR-WSN to support CR-exclusive…
A Novel Cost-Based Model for Data Repairing Abstract? Integrity constraint based data repairing is an iterative process consisting of two parts: detect and group errors that violate given integrity constraints (ICs); and modify values inside each group such that the modified database satisfies those ICs. However, most existing automatic solutions treat the process of detecting…
