3-dimensional solder paste inspection using Structured Light techniques
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2002)Re-modelling of three-dimensional solder paste constructed from optical profilometry has gathered ever-increasing attention in different inspection and process control sectors of the electronics Printed Circuit Board ... -
A generalized method for quantification of cognitive radio benefits within wireless systems
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2009)For most of the history of wireless communications, the primary enabler of enhanced radio communications capability and utility has been continual improvement in the implementing technology and the corresponding ability ... -
A quasi three dimensional numerical model for terrain propagation
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2002)Numerical modeling techniques provide a powerful tool for the optimization of modern land mobile radio communications systems. Mathematically, propagation over terrain constitutes a three-dimensional vector field problem ... -
A semiclassical approach to quantum Brownian motion in Wigner's phase space
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2010)In this thesis, the recent semiclassical approach to quantum Brownian motion of Coffey et al. [Phys. Chem. Chem. Phys. 9, 3361 (2007)] is studied in detail. This approach is based on a semiclassical extension of Wigner's ... -
Accounting for the Local Field When Determining the Dielectric Loss Spectra of Metals in the Region of the Frequencies of Volume, Surface, and Localized Plasmon Oscillations
(2020)The optical constant of bulk metal is used to determine the dispersion of the local field under one-dimensional (1D), two-dimensional (2D) and three-dimensional (3D) confinement. 3D confinement, expressed as ε 2 m i c ( ω ... -
Accurate modelling and synthesis of the Lead 11 ECG signal
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)This thesis is a study of Lead II ECG signal synthesis. The principal problem of EGG signal synthesis is two fold, the first concerns the accuracy of the instrument used to deliver the synthesised signal and the second ... -
Active Damping of Power Oscillations Following Frequency Changes in Low Inertia Power Systems
(2019)The absolute requirement to increase the amount of energy generation from renewable sources e.g. predominantly asynchronously connected wind turbines and photovoltaic installations, may in practice during transient events ... -
Active speaker localisation and tracking using audio and video

Ad hoc key management
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2006)This dissertation analyses the problem of providing Key Management Infrastructure (KMI) in an ad hoc network. A novel solution is proposed designed and implemented that facilitates both types of KMI that are deployed in ... -
Ad hoc Networking, Markov Random Fields, and Decision Making
(2006)Our central proposition is that by articulating decision making in an ad hoc network using a Markov random field (MRF) maximum a posteriori (MAP) approach, a viable decision- making framework can be designed. This ... -
Adaptation in a Channel Access Game with Private Monitoring
(2013)Under the opportunistic spectrum access paradigm, the shared pool of spectrum bands that the multiple autonomous cognitive radios (CRs) need to compete for is not necessarily homogeneous. The non-homogeneity in channels ... -
Adaptation of Reputation Management Systems to Dynamic Network Conditions in Ad Hoc Networks
(2010)Reputation management systems have been proposed as a cooperation enforcement solution in ad hoc networks. Typically, the functions of reputation management (evaluation, detection, and reaction) are carried out homogeneously ... -
Adaptive noncontact gesture-based system for augmentative communication
(IEEE, 1999)An adaptive noncontact gesture-based system for augmentative communication is described. The system detects movement of any anatomical site through the analysis of reflected speckle. This movement is converted into ... -
Advanced video debanding
(ACM, 2014)High efficiency video coding has made it possible to stream video over bandwidth constrained communication networks. Depending on bit rate requirements, a video encoder sacrifices some image de- tails which can then ... -
Algorithmic level low-power VLSI design applied to RGB to HSI conversion
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2001)The growing demand for portable applications such as cellular phones, portable digital assistants (PDAs) and notebooks has resulted in a requirement for integrated circuits (ICs) which consume less power while delivering ... -
Alignment instability caused by anchoring of the in-plane directors to the rubbing direction in the V-shaped switching
(2000)In order to investigate the molecular alignment in the smectic liquid crystals showing the V-shaped switching behavior, two types of the liquid crystal cells, a sandwiched cell and an open cell, were prepared. ... -
Alignment of liquid crystal E7 in composite photonic crystals based on single crystal silicon
(SPIE, 2005)The orientation of nematic liquid crystal (LC) E7 on the surface of (111) silicon wafers and in the channels of grooved silicon structure has been investigated. Grooved Si is a periodical structure obtained by wet anisotropic ... -
Amplifier front-end design in dry-electrode electrocardiography
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2011)This thesis presents an analytical approach to some key issues related to the design of biopotential amplifiers for use in long-term ambulatory recording of the electrocardiogram (ECG) employing pasteless or dry electrodes. ... -
