V2G applicable electric vehicle chargers, power converters & their controllers: A review
(IEEE, 2020-10-20)This paper aims to present various grid-connected electric vehicle (EV) charger topologies with battery technologies and power electronics converters utilized in bidirectional EV chargers including DC/DC synchronous buck ... -
Value iteration algorithm for mean-field games
(Elsevier, 2020-09)In the literature, existence of mean-field equilibria has been established for discrete-time mean field games under both the discounted cost and the average cost optimality criteria. In this paper, we provide a value ... -
The value of quality grading in remanufacturing under quality level uncertainty
(Taylor & Francis, 2021)In remanufacturing, variability in quality levels of available cores (end-of-life products) has an impact on both the process cost and the process time. While previous research suggests that quality grading adds value, ... -
Variability viewpoint for introducing variability in software architecture viewpoints
(ACM, 2012)Variability is the ability of a software system to be changed for a specific context, in a preplanned manner. As such, to facilitate the instantiation of a software architecture the variability concern needs to be explicitly ... -
Variable ankle stiffness improves balance control: experiments on a bipedal exoskeleton
(IEEE, 2016-02)This paper proposes a real-time balance control technique that can be implemented to bipedal robots (exoskeletons, humanoids) whose ankle joints are powered via variable physical stiffness actuators. To achieve active ... -
Variable-sized bin packing problem with conflicts and item fragmentation
(Elsevier, 2022-01)In this paper, we study the Variable-Sized Bin Packing Problem with Conflicts and Item Fragmentation (VSBPPC-IF) that has applications such as (i) the delivery planning of incompatible items using a fleet of heterogenous ... -
Variational bayesian multiple instance learning with gaussian processes
(IEEE, 2017)Gaussian Processes (GPs) are effective Bayesian predictors. We here show for the first time that instance labels of a GP classifier can be inferred in the multiple instance learning (MIL) setting using variational Bayes. ... -
Variational closed-Form deep neural net inference
(Elsevier, 2018-09)We introduce a Bayesian construction for deep neural networks that is amenable to mean field variational inference that operates solely by closed-form update rules. Hence, it does not require any learning rate to be manually ... -
The variational method, backreactions, and the absorption probability in Wald type problems
(Springer, 2021-01-19)We argue that the variational method in Wald type thought experiments, involves order of magnitude problems when one imposes the fact that δM is inherently a first order quantity itself. One observes that the contribution ... -
Vector and axial-vector couplings of D and D⁎ mesons in 2+1 flavor lattice QCD
(Elsevier, 2013-02-12)Using the axial-vector coupling and the electromagnetic form factors of the D and D⁎ mesons in 2+1 flavor lattice QCD, we compute the D⁎Dπ , DDρ and D⁎D⁎ρ coupling constants, which play an important role in describing ... -
Vehicle-to-infrastructure visible light communications: Channel modelling and capacity calculations
(IEEE, 2020)In this paper, we investigate the performance of a visible light communication (VLC) system for vehicle-to-infrastructure (V2I) connectivity. Two headlamps of the vehicle serve as wireless transmitters while photodetectors ... -
Vehicle-to-vehicle visible light communication: How to select receiver locations for optimal performance?
(IEEE, 2019)Visible light communication (VLC) utilizes vehicle headlights as wireless transmitters and has emerged as a strong candidate for vehicle-to-vehicle (V2V) communications. In majority of works on V2V VLC systems, a common ... -
Vehicular visible light communications with SPAD receivers
(IEEE, 2019)Light emitting diodes (LEDs) are increasingly used in automotive exterior lighting. The expected wide availability of LED-based front and back lights makes visible light communication (VLC) a natural vehicular connectivity ... -
Vehicular visible light communications: The impact of taillight radiation pattern
(IEEE, 2020-09)We investigate the path-loss of vehicular visible light communications based on the radiation pattern of a commercial car taillight. The measured pattern is incorporated into a ray-tracing model and simulation results ... -
Vehicular VLC channel model for a low-beam headlight transmitter

Vehicular VLC: A ray tracing study based on measured radiation patterns of commercial taillights
(IEEE, 2021-08-15)In this letter, we investigate the performance of vehicular visible light communications based on the radiation patterns of different commercial taillights (TLs) using non-sequential ray tracing simulations. Our simulation ... -
Velocity pulse effects of near-fault earthquakes on a high-speed railway vehicle-ballastless track-benchmark bridge system
(Taylor & Francis, 2022-09-02)The near fault (NF) line waves send out signal envelopes that oscillate over lengthy periods of time with periodic impulses. Like train bridges, train tracks demonstrate comparable track-bridge (TB) motion dynamics. Using ... -
Verification and analysis of domain-specific models of physical characteristics in embedded control software
(Elsevier, 2012-12)ContextA considerable portion of the software systems today are adopted in the embedded control domain. Embedded control software deals with controlling a physical system, and as such models of physical characteristics ... -
