The Least Square Values and the Shapley Value for Cooperative TU Games
(University of Texas at ArlingtonDepartment of Mathematics, 2003-05)**Please note that the full text is embargoed** ABSTRACT: The Least Square Values (briefly LS-values), represent a family of values for cooperative transferable utility games, introduced by L. Ruiz. F. Valenciano and ... -
The Least-squares Finite Element Method For Grid Deformation And Meshfree Applications
(Mathematics, 2007-08-23)Grid adaptation is often needed to improve the numerical solution of a Partial Differential Equation (PDE), due to, for example, shock waves and boundary layers. In moving boundary problems, the grid needs to be regenerated ... -
LES For Wing Tip Vortex Around An Airfoil
(Mathematics, 2007-08-23)The wing tip vortex is very important because of its effects on the noise generation, blade/vortex interactions on helicopter blades, propeller cavitations on ships, and other fields. The objective of this work is to use ... -
Likelihood Inference for Flexible Cure Models with Interval Censored Data
(2023-05-19)Models for survival data with a surviving fraction, known as cure rate models, play a vital role in survival analysis. Due to the improvement of intervening methodologies, some subjects are seen to be immune permanently. ... -
Likelihood Inference for Flexible Cure Rate Models in the Context of Infectious Diseases with Multiple Exposures
(2020-09-01)Cure rate models are mostly used to study data arising from cancer clinical trials. Its use in the context of infectious diseases has not been explored well. In 2007, Tournoud and Ecochard rst proposed a mechanistic ... -

(University of Texas at ArlingtonDepartment of Mathematics, 1977-05)**Please note that the full text is embargoed** ABSTRACT: An algorithm is presented for identifying exponentials sums [see pdf for notation] from discrete data [see pdf for notation] The algorithm determines the number ... -
Linear Monotone Method for Nonlinear Boundary Value Problems in Banach Spaces
(University of Texas at ArlingtonDepartment of Mathematics, 1981-05)**Please note that the full text is embargoed** ABSTRACT: One of the most useful techniques in proving the existence of multiple solutions of nonlinear boundary value problems (BVP for short) is the monotone iterative ... -
LIUTEX ANALYSIS BY POD AND DMD FOR VORTEX FORMATIONS IN BOUNDARY LAYER TRANSITION
(2019-12-05)Vortices are considered as the building blocks of turbulent flows. To study how one type of vortex becomes another type especially in flow transition is one way to get better understanding about turbulence. In this ... -
LIUTEX ANALYSIS BY POD AND DMD IN TURBULENT FLOW AFTER/ IN MICRO VORTEX GENERATOR
(2021-12-06)Although vortex has been studied more than one hundred year, we still have not had universally accepted definition. A few well-known vortex identification methods are introduced 𝑄,∆, 𝜆2,𝜆𝑐𝑖 criteria to identify coherent ... -
LIUTEX AND STATISTICAL ANALYSIS FOR FLUID TRANSITION
(2021-08)A vortex can be intuitively recognized as the rotational swirling motion of the fluids. The fascination of this phenomenon brought about many years of research to define, classify, and identify the vortical structure. ... -
LIUTEX-BASED VORTEX IDENTIFICATION METHODS AND THEIR APPLICATION IN DNS STUDY OF FLAT PLATE BOUNDARY LAYER TRANSITION
(2021-07-26)Vortices are intuitively known as the rotational motion of fluid particles, however, unambiguous and universally accepted methods of vortex definition and identification are not available to date in the literature. ... -
Local Atomic Temperature
(University of Texas at ArlingtonDepartment of Mathematics, 1989-10)**Please note that the full text is embargoed** ABSTRACT: For the study of phase-transition by molecular dynamics, the concept of local temperature is desirable. Such a concept is defined and studied in this paper. From ... -
Local Molecular Temperature
(University of Texas at ArlingtonDepartment of Mathematics, 1989-11)**Please note that the full text is embargoed** ABSTRACT: For the study of phase-transition by molecular dynamics, the concept of local temperature is desirable. Such a concept, defined and studied previously for atoms, ... -
Logistic Regression With Misclassified Covariates Using Auxiliary Data
(Mathematics, 2009-09-16)When standard regression methods are used, measurement errors cause a bias in parameters estimation. In dealing with discrete covariates, such measurement errors are known as misclassification and the corresponding discrete ... -
