V2G applicable electric vehicle chargers, power converters & their controllers: A review
(IEEE, 2020-05-27)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 ... -
Validation and comparison of 2D and 3D numerical simulations of flow in simplex nozzles
(Europe, Institute for Liquid Atomization and Spray Systems, ILASS, 2021-08-31)Numerical simulations of pressure swirl atomizers are computationally expensive due to transient and multiphase flow behavior. In this study, 2D and 3D VOF simulations are performed for a geomerty which has high swirl ... -
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 ... -
A variable neighborhood search based matheuristic for a waste cooking oil collection network design problem
(Elsevier, 2022-10)Households produce large amounts of waste cooking oil (WCO), which should be disposed properly to avoid its negative impacts on the environment. Using WCO as raw material in biodiesel production is an effective disposal ... -
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 ... -
