Typicality-Based Collaborative Filtering Recommendation Abstract? Collaborative filtering (CF) is an important and popular technology for recommender systems. However, current CF methods suffer from such problems as data sparsity, recommendation inaccuracy, and big-error in predictions. We borrow ideas of object typicality from cognitive psychology and propose a novel typicality-based collaborative filtering recommendation method named TyCo. A…
U-Skyline: A New Skyline Query for Uncertain Databases Abstract? U-Skyline: A New Skyline Query for Uncertain Databases.U-Skyline: A New Skyline Query for Uncertain Databases The skyline query, aiming at identifying a set of skyline tuples that are not dominated by any other tuple, is particularly useful for multicriteria data analysis and decision making. For uncertain…

Recent research…
ubiSOAP A Service Oriented Middleware for Ubiquitous Networking. Abstract? The computing and networking capacities of today’s wireless portable devices allow for ubiquitous services, which are seamlessly networked. Indeed, wireless handheld devices now embed the necessary resources to act as both service clients and providers.< Final Year Projects > However, the ubiquitous networking of services remains…
Ultralow-Voltage High-Speed Flash ADC Design Strategy Based on FoM-Delay Product Abstract? The ultralow-voltage (ULV) design strategy for high-speed flash analog-to-digital converters (ADCs). A lower supply voltage decreases the energy consumption at the cost of conversion speed. A new index, the figure-of-merit (FoM)-delay (FD) product, is introduced to provide a balance between the energy efficiency and…
Unified VLSI architecture for photo core transform used in JPEG XR Abstract? In JPEG XR image compression technique the unified photo core transform is used. It is designed to support high dynamic range and high definition formats thus this type of JPEG XR image compression with unified photo core transform is widely used in real…
UNION: A Unified Inter/Intrachip Optical Network for Chip Multiprocessors Abstract?As modern computing systems become increasingly complex, communication efficiency among and inside chips has become as important as the computation speeds of individual processing cores. Traditionally, to maximize design flexibility, interchip and intrachip communication architectures are separately designed under different constraints. Jointly designing communication architectures for…
Universal Network Coding-Based Opportunistic Routing for Unicast Abstract?Universal Network Coding-Based Opportunistic Routing for Unicast. Network coding-based opportunistic routing has emerged as an elegant way to optimize the capacity of lossy wireless multihop networks by reducing the amount of required feedback messages. Most of the works on network coding-based opportunistic routing in the literature assume that…
Unprivileged Black-Box Detection of User-Space Keyloggers Abstract?Software keyloggers are a fast growing class of invasive software often used to harvest confidential information. One of the main reasons for this rapid growth is the possibility for unprivileged programs running in user space to eavesdrop and record all the keystrokes typed by the users of a system.<...
Unraveling the Effect of Textured Contact Lenses on Iris Recognition Abstract?Unraveling the Effect of Textured Contact Lenses on Iris Recognition. The presence of a contact lens, particularly a textured cosmetic lens, poses a challenge to iris recognition as it obfuscates the natural iris patterns. The main contribution of this paper is to present an in-depth…
Unsupervised Colour Image Segmentation using Dual-tree Complex Wavelet Transform Abstract?a novel image segmentation technique for noisy colour images, in which the heavy-tailed characteristics of the image are modelled by Cauchy distributions. First, the RGB colour bands of the noisy image are decomposed into multiresolution representations using the dual-tree complex wavelet transform.< Final Year Project >…
Unsupervised Feature Selection with Controlled Redundancy (UFeSCoR) Abstract? Unsupervised Feature Selection with Controlled Redundancy (UFeSCoR). Features selected by a supervised / unsupervised technique often include redundant or correlated features. While use of correlated features may result in an increase in the design and decision making cost, removing redundancy completely can make the system vulnerable to…
