Popular Content Distribution in Public Transportation Using Artificial Intelligence Techniques
(University of Waterloo, 2019-08-20)Outdoor wireless networks suffer nowadays from an increasing data traffic demand which comes at the time where almost no vacant frequency spectrum has been left. A vast majority of this demand comes from popular content ... -
Population-level Indicators of Physical Activity, Sedentary Behaviour and Sleep in Canada based on Twitter
(University of Waterloo, 2018-08-17)Social media platforms contain large amounts of freely and publicly available data that could be used to measure population characteristics across different geographical regions. Analyzing public data sources such as ... -
Pose Estimation and Segmentation for Rehabilitation
(University of Waterloo, 2015-10-01)The global population is getting older and the aging demographic is increasing demands on health-care industry. This will drive the demand for post stroke, joint replacement, and chronic disease management rehabilitation. ... -
Post-mapping Topology Rewriting for FPGA Area Minimization
(University of Waterloo, 2009-08-26)Circuit designers require Computer-Aided Design (CAD) tools when compiling designs into Field Programmable Gate Arrays (FPGAs) in order to achieve high quality results due to the complexity of the compilation tasks involved. ... -
Power Analysis of Sub-threshold Logics for Security Applications
(University of Waterloo, 2012-09-26)Requirements of ultra-low power for many portable devices have drawn increased attention to digital sub-threshold logic design. Major reductions in power consumption and frequency of operation degradation due to the ... -
Power Characterization of a Digit-Online FPGA Implementation of a Low-Density Parity-Check Decoder for WiMAX Applications
(University of Waterloo, 2014-06-17)Low-density parity-check (LDPC) codes are a class of easily decodable error-correcting codes. Published parallel LDPC decoders demonstrate high throughput and low energy-per-bit but require a lot of silicon area. Decoders ... -
Power Characterization of a Gbit/s FPGA Convolutional LDPC Decoder
(University of Waterloo, 2012-08-31)In this thesis, we present an FPGA implementation of parallel-node low-density-parity-check convolutional-code (PN-LDPC-CC) encoder and decoder. A 2.4 Gbit/s rate-1/2 (3, 6) PN-LDPC-CC encoder and decoder were implemented ... -
Power Generation Shortage in Developing Countries: Causes, Challenges and Solutions
(University of Waterloo, 2015-08-14)Electricity consumers in developing countries are seeking reliable electricity services to subsidize the economy and assist the rising population. Underprivileged electricity services are major concerns for these consumers ... -
Power Management for Deep Submicron Microprocessors
(University of Waterloo, 2008-07-18)As VLSI technology scales, the enhanced performance of smaller transistors comes at the expense of increased power consumption. In addition to the dynamic power consumed by the circuits there is a tremendous increase in ... -
Practical interference management strategies in Gaussian networks
(University of Waterloo, 2016-09-14)Increasing demand for bandwidth intensive activities on high-penetration wireless hand-held personal devices, combined with their processing power and advanced radio features, has necessitated a new look at the problems ... -
Practical Multi-Interface Network Access for Mobile Devices
(University of Waterloo, 2012-09-25)Despite the growing number of mobile devices equipped with multiple networking interfaces, they are not using multiple available networks in parallel. The simple network selection techniques only allow for single network ... -
Practical Routing in Delay-Tolerant Networks
(University of Waterloo, 2006)Delay-tolerant networks (DTNs) have the potential to connect devices and areas of the world that are under-served by traditional networks. The idea is that an end-to-end connection may never be present. To make ... -
Precise Timing of Digital Signals: Circuits and Applications
