Uncertainty in risk of highway bridges assessed for integrated seismic and flood hazards
(Taylor and Francis, 2017-11-24)Probabilistic risk assessment for bridges under natural hazards is of great interest to engineers for the development of risk mitigation strategies and implementation plans. The present study evaluates risk of an existing ... -
Uncertainty-aware deep classifiers using generative models
(Association for the Advancement of Artificial Intelligence, 2020)Deep neural networks are often ignorant about what they do not know and overconfident when they make uninformed predictions. Some recent approaches quantify classification uncertainty directly by training the model to ... -
Uncertainty-aware situational understanding
(SPIE, 2019)Situational understanding is impossible without causal reasoning and reasoning under and about uncertainty, i.e. prob-abilistic reasoning and reasoning about the confidence in the uncertainty assessment. We therefore ... -
Understanding selectivity on Germanium/SiO2 chemical mechanical planarization through design of experiments
(Cambridge University Press, 2015)The continuous trend of achieving more complex microelectronics with smaller nodes yet larger wafer sizes in microelectronics manufacturing lead to aggressive development requirements for chemical mechanical planarization ... -
Underwater visible light communications in cascaded gamma-gamma turbulence
(IEEE, 2018)In this paper, we investigate the performance of vertical underwater visible light communication (VLC) links in the presence of moderate and strong turbulence conditions using Gamma-Gamma (GG) probability density function. ... -
Unidirectional wave motion in a nonlocally and nonlinearly elastic medium: The KdV, BBM and CH equations
(Estonian Academy of Sciences, 2015)We consider unidirectional wave propagation in a nonlocally and nonlinearly elastic medium whose constitutive equation is given by a convolution integral with a suitable kernel function. We first give a brief review of ... -
A unified Monte Carlo treatment of the transport of electromagnetic energy, electrons, and phonons in absorbing and scattering media
(Elsevier, 2010-02)The scalar Boltzmann transport equation (BTE) is often applicable to radiative energy transfer, electron–beam propagation, as well as thermal conduction by electrons and phonons provided that the characteristic length of ... -
Unified performance analysis of multi-hop FSO systems over double generalized gamma turbulence channels with pointing errors
(IEEE, 2020-11)Free space optical (FSO) communication systems provide high bandwidth in unregulated spectrum and act as a powerful line-of-sight wireless connectivity solution. The performance of FSO systems can be seriously impaired by ... -
Unified resource allocation and mobility management technique using particle swarm optimization for VLC networks
(IEEE, 2018-12)In this paper, we present a unified resource allocation and mobility management algorithm based on particle swarm optimization (PSO) for indoor visible light communication (VLC) networks. We consider a VLC network where ... -
Unlocking the effect of H2O on CO2 separation performance of promising MOFs using atomically detailed simulations
(ACS Publications, 2020-02-19)Metal organic frameworks (MOFs) have been considered as potential adsorbents for adsorption-based CO2/CH4 and CO2/N-2 separations because of their high CO2 selectivities and high working capacities. H2O in flue gas and ... -

Unmanned-aerial-vehicle-assisted cooperative communications for visible light communications-based vehicular networks
(SPIE, 2019-08)We propose and investigate cooperative visible light communications (VLC) enabled vehicular network architecture with an unmanned aerial vehicle (UAV) relay. In the proposed system, a UAV equipped with an onboard photodetector ... -
Upsilon (nS) polarizations versus particle multiplicity in pp collisions at root s=7 TeV
(Elsevier, 2016-10)The polarizations of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) mesons are measured as a function of the charged particle multiplicity in proton-proton collisions at root s = 7 TeV. The measurements are performed with ... -
Use of biomineralisation in developing smart concrete inspired by nature
(Inderscience, 2015)Recently, interest has focused on leveraging the biological functions of microorganisms to develop smart cement-based materials. This paper provides an overview of the calcium carbonate biomineralisation process in nature ... -
Use of corn-steep liquor as an alternative carbon source for biomineralization in cement-based materials and its impact on performance
(Elsevier, 2018-03-20)Early age microcracks are generally the primary cause for a decrease in service life of cement-based structures. Recent studies suggested that it might be possible to develop a smart cement-based material that could self-heal ... -
Use of line spectral frequencies for emotion recognition from speech
(IEEE, 2010)We propose the use of the line spectral frequency (LSF) features for emotion recognition from speech, which have not been been previously employed for emotion recognition to the best of our knowledge. Spectral features ... -
Use of natural minerals to immobilize bacterial cells for remediating cracks in cement-based materials
(ASCE, 2022-03-01)Cracks in cement-based materials are one of the main factors affecting the durability of structure. Recent research in the field of concrete materials showed that self-healing in cement-based systems can be achieved by ... -
Use of pre-wetted lightweight fine expanded shale aggregates as internal nutrient reservoirs for microorganisms in bio-mineralized mortar
(Elsevier, 2017-11)Interest in developing bio-based self-healing cement-based materials has gained broader attention in the concrete community. One of challenges in developing bio-based self-healing cement-based materials is that cell death ... -
Using artificial neural networks to provide guidance in extending PL/SQL programs
(Springer, 2022-12)Extending legacy systems with new objects for contemporary functionality or technology can lead to architecture erosion. Misplacement of these objects gradually hampers the modular structure, of which documentation is ... -
Using convolutional neural networks to automate aircraft maintenance visual inspection
(MDPI, 2020-12)Convolutional Neural Networks combined with autonomous drones are increasingly seen as enablers of partially automating the aircraft maintenance visual inspection process. Such an innovative concept can have a significant ...
