Bandwidth-adaptive waveforms for dynamic spectrum access networks
(IEEE, 2008)This paper presents a novel solution to the challenge of waveform bandwidth estimation in DySPAN systems using intentionally embedded cyclostationary signatures. Dynamic spectrum access networks (DySPANs) achieve high ... -
Barriers to Sustainable Transport in Ireland
(Environmental Protection Agency, 2011)This synthesis report provides an overview of the findings from the Assessing the Barriers to SustainableTransport in Ireland project and distils the conclusions outlined in the End of Project Report. The purpose of this ... -
Basis of serviceability limit state target reliability: Fact or fiction?
(2023)Target reliability forms the basis of modern structural design and finds its root in cost optimisation. Ultimate limit state (ULS) target reliability is well-founded and has been extensively researched. Serviceability limit ... -
Battery Charging Considerations in Small Scale Electricity Generation from a Thermoelectric Module
(2014)This project involves the development of a prototype electrical gen erator for delivering and storing small amounts of electricity. Power is generated using the thermoelectric effect. A single ... -
Bayesian empirical vulnerability modelling for hierarchical levels of damage and loss: Applications to Tsunami Risk Modelling
(2023)Empirical fragility and vulnerability curves express the probabilities of exceeding certain damage and loss levels respectively for given values of intensity measures for specific classes of building or infrastructure. ... -
Bayesian example based segmentation using a hybrid energy model
(IEEE, 2007)This paper describes a supervised segmentation algorithmwhich draws inspiration from recent advances in non-parametric texture synthesis. A set of example images which have been segmented a priori are used as a guide ... -
A Bayesian Framework for Recursive Object Removal in Movie Post-Production
(IEEE, 2003)Some of the most convincing film and video effects are created in digital post-production by removing apparatus that supports or manipulates actors and objects. Wires and people, for instance, can be removed by digitally ... -
Bayesian hierarchical modelling of bridge traffic loading across a road network
(2023)The prediction of extreme traffic loading is a crucial part of bridge design and assessment. It provides a basis of how much action, and conversely the strength required for a bridge in its lifetime. However, there remain ... -
Bayesian Inference and Maximum Likelihood Estimation for fitting Distribution Functions of Road Traffic Load Effects
(2023)More and more bridges reach the end of their design life. Traffic loads have changed substantially over the last few decades since the design of these bridges. To prevent unnecessary costs and material use in redesign or ... -
Bayesian neural networks for large-scale infrastructure deterioration models
(2023)State-space models (SSM) have been shown to be effective at modelling structural deterioration of transportation infrastructure based on visual inspections. The SSM approach was recently coupled with kernel regression (KR) ... -
Bayesian Neural Networks for Probabilistic Surrogate Models ﾖ Uncertainty Quantification, Propagation, and Sensitivity Analysis
(2023)Neural networks are powerful function approximators which scale to problems having large input dimensionality. Bayesian neural networks are an interesting choice for surrogate models as they (1) natively enable performing ... -
Bayesian Optimization for Intrinsically Noisy Response Surfaces
(2023)While Bayesian optimization (BO) is a well-established method for efficient optimization of deterministic response surfaces that are time intensive to evaluate, its application for the optimization of stochastic response ... -
The Beauty of Twist-Bend Nematic Phase: Fast Switching Domains, First Order Fréedericksz Transition and a Hierarchy of Structures
(2021)The twist-bend nematic phase (NTB) exhibits a complicated hierarchy of structures responsible for several intriguing properties presented here. These are: the observation of a fast electrooptic response, the exhibition of ... -
Behaviour and Properties of Lime-Pozzolan Pastes
(2010)Lime pozzolan mortars have been used by numerous ancient civilizations of builders, and are now regaining popularity as environmental sustainable alternatives to cements for masonry and concrete applications. This paper ... -
Bernstein adaptive nonparametric conditional sampling: a new method for rare event probability estimation
(2023)Reliability analysis often requires estimating small failure probabilities, associated with rare events. To overcome their intractable crude Monte Carlo estimation, various techniques have been proposed. Among others, ... -
Biaxial order and a rotation of the minor director in the nematic phase of an organo-siloxane tetrapode by the electric field
(2012)Biaxiality in the nematic phase for a liquid crystalline tetrapode made up of organo-siloxanes mesogens is investigated using polarized infrared spectroscopy. An ordering of the minor director for the homeotropically aligned ... -
Biaxial order parameter in the homologous series of orthogonal bent-core smectic liquid crystals
(2013)The fundamental parameter of the uniaxial liquid crystalline state that governs nearly all of its physical properties is the primary orientational order parameter (S) for the long axes of molecules with respect to the ...
