A multiblock/multilevel mesh refinement procedure for CFD computations

International Journal for Numerical Methods in Fluids, 2001
AbstractA multiblock/multilevel algorithm with local refinement for general two‐ and three‐dimensional fluid flow is presented. The patched‐based local refinement procedure is presented in detail and algorithmic implementations are also presented. The multiblock implementation is essentially block‐unstructured, i.e.

Mathematical proof of a harmonic elimination procedure for multilevel inverters

Mathematics and Computers in Simulation, 2021
Abstract In this paper, a single phase cascaded H-bridge inverter with s variable dc sources ( s ≥ 2 ), l = 2 s + 1 levels has been considered. A mathematical proof is presented to demonstrate that, under a particular choice of the switching angles, which number corresponds to the number of dc sources i.e.

A multilevel analysis of procedural justice context

Journal of Organizational Behavior, 1998
Summary Using a multilevel framework, we hypothesized that both employee perceptions ofprocedural justice and a work unit level measure of procedural justice context would beassociated with employee reports of job satisfaction and organizational commitment.Three hundred and twenty-three employees from 53 branches of a financial servicesorganization were

Doubly Latent Multilevel Procedures for Organizational Assessment and Prediction

Journal of Business and Psychology, 2021
Organizational research has a rich tradition of multilevel investigations anchored in a long-standing recognition that conclusions obtained at the individual level of analysis cannot be expected to generalize at other levels. Doubly latent multilevel methods, which provide the way to combine multilevel analyses and structural equation models into a ...

On Parameters Estimation Procedures in Multilevel Models

SSRN Electronic Journal, 2004
We examine maximum likelihood estimation procedures in multilevel models relatedbto two-level hierarchically structured data. Usually, for fixed effects and variance components estimation, multivariate normal distribution is assumed. Here we consider for random effects multivariate exponential power distribution (MEP), which represents one of the ...

TORS in a Multilevel Procedure

2016
Current surgical management of obstructive sleep apnea (OSA) is most successfully achieved by multilevel surgery. This was confirmed after thorough understanding of the complexity of airway obstruction by drug-induced sleep endoscopy (DISE) that showed that the hypopharynx and base of tongue, not only the palate, are important anatomic components of ...

A multilevel training procedure for speech recognition in noise

The Journal of the Acoustical Society of America, 1998
A multilevel training procedure is proposed for automatic speech recognition in noise. In the multilevel training procedure, six levels of Gaussian noise, corresponding to six signal-to-noise ratios (SNR), were added to the training samples. The procedure was tested in three speech recognizers implemented, respectively, on the basis of the following ...
