Two-Level QR Code for Private Message Sharing and Document Authentication Abstract? The quick response (QR) code was designed for storage information and high-speed reading applications. We present a new rich QR code that has two storage levels and can be used for document authentication. This new rich QR code, named two-level QR code, has public…
Two-Way OFDM-Based Nonlinear Amplify-and-Forward Relay Systems Abstract? We derive closed-form outage probability expressions for fixed-gain (FG) and variable-gain (VG) two-way amplify-and-forward (AF) relay networks subject to a nonlinear transmission at the relay. We then derive an explicit expression for the relay gain that optimizes the network?s performance. Finally, we show that, if the source nodes…
Two-Way Satellite Relaying With Estimated Channel Gains Abstract? we consider the two-way relaying of the data of two earth stations (ESs) via satellite links. The satellite is considered to be of transparent type, which only receives the signals over the uplink and broadcasts these signals with some transponder gain over its downlink frequencies. The two-way…
Ultra-Low Power, Highly Reliable, and Nonvolatile Hybrid MTJ/CMOS Based Full-Adder for Future VLSI Design Abstract– Very large-scale integrated circuit (VLSI) design, based on today?s CMOS technologies, are facing various challenges. Shrinking transistor dimensions, reduction in threshold voltage, and lowering power supply voltage, cause new concerns such as high leakage current, and increase in radiation sensitivity….
Ultrasound Image Denoising using a Combination of Bilateral Filtering and Stationary Wavelet Transform Abstract?Abstract Medical image degradation has a significant impact on image quality, and thus affects human interpretation and the accuracy of computer-assisted diagnostic techniques.Unfortunately, Ultrasound images are mainly degraded by an intrinsic noise called speckle. Therefore, despekle filtering is a critical preprocessing step…
Uncertain Data Clustering in Distributed Peer-to-Peer Networks Abstract-In general, Uncertain data clustering has been recognized as an essential task in the research of data mining. Many centralized clustering algorithms are extended by defining new distance or similarity measurements to tackle this issue. With the fast development of network applications, these centralized methods show their limitations…
Underwater Image Restoration based on Image Blurriness and Light Absorption Abstract?Abstract Underwater images often suffer from color distortion and low contrast because light is scattered and absorbed when traveling through water. Such images with different color tones can be shot in various lighting conditions, making restoration and enhancement difficult. We propose a depth estimation method…
Unified Opportunistic Scheduling for Layered Multicast over Cognitive Radio Networks Abstract?We investigate the multicast of layered multimedia content in single hop cognitive radio (CR) networks and ways of improving the subscriber utility. < final year projects > [numbers_sections number=”1″ title=”Including =Packages=” last=”no” ] Complete Source Code Complete Documentation Complete Presentation Slides Flow Diagram Database File…
Unified power flow controller based reactive power dispatch using oppositional krill herd algorithm Abstract?Abstract Medical image degradation has a significant impact on image quality, and thus affects human interpretation and the accuracy of computer-assisted diagnostic techniques.Unfortunately, Ultrasound images are mainly degraded by an intrinsic noise called speckle. Therefore, despekle filtering is a critical preprocessing step…
Unsupervised Deep Feature Extraction for Remote Sensing Image Classification Abstract? The use of single layer and deep convolutional networks for remote sensing data analysis. Direct application to multi- and hyper-spectral imagery of supervised (shallow or deep) convolutional networks is very challenging given the high input data dimensionality and the relatively small amount of available labelled…
Unsupervised Visual Hashing with Semantic Assistant for Content-based Image Retrieval Abstract?Abstract As an emerging technology to support scalable content-based image retrieval (CBIR), hashing has been recently received great attention and became a very active research domain. In this study, we propose a novel unsupervised visual hashing approach called semantic-assisted visual hashing (SAVH).Distinguished from semi-supervised and…
Uplink Energy-Delay Trade-Off under Optimized Relay Placement in Cellular Networks Abstract? Relay nodes-enhanced architectures are deemed a viable solution to enhance coverage and capacity of nowadays cellular networks. Besides a number of desirable features, these architectures reduce the average distance between users and network nodes, thus allowing for battery savings for users transmitting on the…
