Band structures of cylindrical AlN/GaN quantum dots with fully coupled piezoelectric models
(Proceedings of SPIE - The International Society for Optical Engineering, 2010-12-31)We study the coupled electro-mechanical effects in the band structure calculations of low dimensional semiconductor nanostructures (LDSNs) such as AlN/GaN quantum dots. Some effects in these systems are essentially nonlinear. ... -
Band structures of laterally coupled quantum dots, accounting for electromechanical effects
(Journal of Physics: Conference Series, 2010-12-31)In a series of recent papers we demonstrated that coupled electro-mechanical effects can lead to pronounced contributions in band structure calculations of low dimensional semiconductor nanostructures (LDSNs) such as quantum ... -
Bayesian inference for algorithm ranking analysis
(GECCO 2018 Companion - Proceedings of the 2018 Genetic and Evolutionary Computation Conference Companion 6 July 2018, Pages 324-325, 2018-08-30)The statistical assessment of the empirical comparison of algorithms is an essential step in heuristic optimization. Classically, researchers have relied on the use of statistical tests. However, recently, concerns about ... -
Bayesian nonparametric inference for the covariate-adjusted ROC curve
(2018-05-30)Accurate diagnosis of disease is of fundamental importance in clinical practice and medical research. Before a medical diagnostic test is routinely used in practice, its ability to distinguish between diseased and nondiseased ... -
BBIPED: BCAM-Baltogar Industrial Platform for Engineering Design
(18th International Conference on Circuits, Systems, Communications and Computers (CSCC 2014); Advances in Engineering Mechancis and Materials, Proc.the International Conference; on Industrial Engineering (INDE 2014)", 2014-12-31)Currently, commercial software for computational fluid dynamics offers a good set of features to deal with traditional designs. Within a competitive market industrial innovation is a key factor that must be faced by ... -
Belief Condensation Filtering For Rssi-Based State Estimation In Indoor Localization
(2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019)Recent advancements in signal processing and communication systems have resulted in evolution of an intriguing concept referred to as Internet of Things (IoT). By embracing the IoT evolution, there has been a surge of ... -
Berry phase and spin precession without magnetic fields in semiconductor quantum dots
(EUROPEAN PHYSICAL JOURNAL B, 2019)We investigate electric field control of spin manipulation through Berry phase in III-V semiconductor quantum dots. By utilizing degenerate and non-degenerate perturbation theories, we diagonalize the total Hamiltonian of ... -
Best constants and Pohozaev identity for hardy-sobolev-type operators
(Communications in Contemporary Mathematics, 2013-12-31)This paper is threefold. Firstly, we reformulate the definition of the norm induced by the Hardy inequality (see [J. L. Vázquez and N. B. Zographopoulos, Functional aspects of the Hardy inequality. Appearance of a hidden ... -
A beta-binomial mixed-effects model approach for analysing longitudinal discrete and bounded outcomes
(Biometrical Journal, 2018-05)Patient-reported outcomes (PROs) are currently being increasingly used as primary outcome measures in observational and experimental studies since they inform clinicians and researchers about the health-status of patients ... -
Bilinear Calderón--Zygmund theory on product spaces
(Journal des Math\'ematiques Pures et Appliqu\'ees, 2019-10)We develop a wide general theory of bilinear bi-parameter singular integrals $T$. This includes general Calder\'on--Zygmund type principles in the bilinear bi-parameter setting: easier bounds, like estimates in the Banach ... -
Bilinear identities involving the $k$-plane transform and Fourier extension operators
(2019)We prove certain $L^2(\mathbb{R}^n)$ bilinear estimates for Fourier extension operators associated to spheres and hyperboloids under the action of the $k$-plane transform. As the estimates are $L^2$-based, they follow from ... -
Bilinear representation theorem
(Transactions of the American Mathematical Society, 2018-01-01)We represent a general bilinear Calderón--Zygmund operator as a sum of simple dyadic operators. The appearing dyadic operators also admit a simple proof of a sparse bound. In particular, the representation implies a so ... -
A Bilinear Strategy for Calderón's Problem
(2019-08)Electrical Impedance Imaging would suffer a serious obstruction if for two different conductivities the potential and current measured at the boundary were the same. The Calder\'on's problem is to decide whether the ... -
Bloom type inequality for bi-parameter singular integrals: efficient proof and iterated commutators
