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 automated detection of focal EEG signals using empirical wavelet transform Abstract-In the first place,the determination of epileptogenic area is a prime task in presurgical evaluation. The seizure activity can be prevented by operating the affected areas by clinical surgery. In this paper, an automatic approach has been presented to detect electroencephalogram…
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 Color Image Encryption Scheme Using Rectangular Transform-Enhanced Chaotic Tent Maps Abstract– In recent years, the chaos-based cryptographic algorithms have attracted a lot of attention. Specially, chaotic tent map (CTM)-based schemes show some good performances in randomness properties and security level. However, several shortcomings still can be found from them. In this paper, based…
A Novel Continuous Blood Pressure Estimation Approach Based on Data M ining Techniques Abstract-Continuous blood pressure (BP) estimation using pulse transit time (PTT) is a promising method for unobtrusive BP measurement. However, the accuracy of this approach must be improved for it to be viable for a wide range of applications. This study proposes a…
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…
A Novel Data Mining Approach for Soil Classification Abstract? Decision tree is a well known approach for classification in data mining. C4.5 and Classification and Regression Trees (CART) are two widelv used decision tree algorithms for classification. The main? drawback of C4.5 algorithm is that, it is biased towards attributes with more values while CART…
A Novel DC-Power Control Method for Cascaded H-Bridge Multilevel Inverter Abstract– The cascaded H-bridge converter has been widely used in industry. The ability of dealing with unequal power generation among dc links is necessarily required in many applications, such as large-scale photovoltaic power plants and electric vehicles.A simplified modulation strategy is introduced to implement the…
