Radar, TV, and Cellular Bands: Which Spectrum Access Technique for Which Bands?
(2014)Opportunistic access has been considered by regu- lators for a number of different spectrum bands. In this paper, we discuss and qualitatively evaluate techniques used in the discovery of spectrum opportunities, also ... -
Radical plumbers and playpumps
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2011)This thesis analyses the PlayPump, a water pump powered by a children's roundabout, which is designed for use in the developing world. The PlayPump is analysed as an example of 'design for development', an area of current ... -
Radio Access Network and Spectrum Sharing in Future Mobile Networks
(2016)Future mobile networks will be characterized by wide-spread resource sharing, and a more nuanced view of what it means to offer a mobile service. The traditional view of a mobile network as a system that simply delivers ... -
Rapid Thermal Oxidation of Ge-rich Strained Layers
(IEEE, 2004)In this paper, we repolt for thejirsr time the electrical properties ofultrathin oxides grown using rapid thermal oxidation (RTO) on strained Ge-rich layers on relaxed-SiGe buffers. Rapid thermal oxidation on strained ... -
Real-time out-of-band interference reduction for OFDM-based systems
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)Interference reduction for OFDM-based systems is of increasing interest in new technologies such as dynamic spectrum access networks. In the past decade, many approaches have been proposed for reducing the interference of ... -
Real-time zero-day Intrusion Detection System for Automotive Controller Area Network on FPGAs
(2023)Increasing automation in vehicles enabled by in- creased connectivity to the outside world has exposed vulnerabilities in previously siloed automotive networks like controller area networks (CAN). Attributes of CAN such ... -
Reconfigurable OFDM systems
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2005)Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier wireless transmission technique. OFDM is used for robust, high quality and high data-rate music, voice, images, video, news and data broadcasts. It is ... -
Reconfigurable software radio systems
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2004)Software radio has been heralded as a significant evolutionary step for wireless technology as it allows dedicated analogue radio hardware to be replaced with flexible digital signal processing. Due to current technological ... -
Relationship between the molecular interaction and the structure of the bent core liquid crystals in the nematic phase
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)The relationship between the molecular interaction and the molecular structure of the bent core mesogens in the nematic phase is investigated in detail. Various physical phenomena are observed and interpreted. -
Relaxation time for nonlinear response of a Brownian particle subject to a step external force: Analytical solutions for one-dimensional models
(American Physical Society, 1997)The nonlinear response to a step external force of a system with relaxational dynamics governed by a one-dimensional Fokker-Planck equation is considered. An exact analytical expression for the step response nonlinear ...
