Nonlinear Finite Element Model Analysis Of Human Accommodation Lens
(Civil & Environmental Engineering, 2007-08-23)The crystalline human lens is modeled by using the finite element software, ABAQUS/CAE Version 6.5-1 as an axisymmetric shell to study the optical power and displacement of anterior and posterior poles induced due to zonule ... -
Nonlinear Finite Element-based Investigation Of The Effect Of Bedding Thickness On Underground Pipe
(Civil & Environmental Engineering, 2007-08-23)The pipe-soil interaction is studied by using the finite element software, ABAQUS/CAE Version 6.5-1 as a symmetric model of embankment installation to study the effect of bedding property and thickness on pipe-soil interaction ... -
Nonlinear H2/H∞ Constrained Feedback Control: A Practical Design Approach Using Neural Networks
(Electrical Engineering, 2007-08-23)In this research, practical methods for the design of H2 and H∞ optimal state feedback controllers for constrained input systems are proposed. The dynamic programming principle is used along with special quasi-norms to ... -
NONLINEAR MODE COUPLING COEFFICIENTS IN EXTRASOLAR HOT JUPITER SYSTEMS WITH NON-SOLAR TYPE HOST STARS
(2021-12-23)Short period planets tidally excite internal gravity modes within their host star. These excited modes, known collectively as the dynamical tide, dissipate orbital energy and cause the planet’s orbit to decay. In hot Jupiter ... -
Nonlinear Model Predictive Control for Cooperative Control and Estimation
(2017-06-08)Recent advances in computational power have made it possible to do expensive online computations for control systems. It is becoming more realistic to perform computationally intensive optimization schemes online on systems ... -
Nonlinear Optics and Bio-sensing with Silicon Nitride Waveguides
(2019-12-06)Silicon Nitride (SiN) is a CMOS compatible optical material that can be used for both linear and nonlinear optics applications. SiN has high refractive index (1.99-2.0) and low two photon absorption (TPA) coefficient. As ... -
NONPARAMETRIC ADAPTIVE DISTRIBUTION-FREE PROCEDURE FOR CROSSOVER DESIGN WITH REPEATED MEASURES
(2017-05-11)We propose to apply adaptive nonparametric procedures (Hill, Padmanabhan, & Puri, 1988) on 2x2 crossover design with repeated measures. We will derive the test-statistics (based on function of ranks) and find their ... -
Nonprofit Employee Recognition: An Intrinsically-based Program
(Social Work, 2011-03-03)This study hypothesizes that nonprofit employees will choose non-monetary motivational factors based on intrinsic values over monetary factors such as better pay, benefits, etc. when asked what is most important. Limited ... -
NONPROFIT MARKETING AND COMMUNICATION PERSONNEL JOB SATISFACTION: THE EFFECTS OF ROLE CONFLICT AND ROLE AMBIGUITY
(2023-05-01)Job satisfaction is becoming increasingly important in efforts to retain employees across all sectors. The nonprofit sector is facing greater challenges than ever before in competing for and retaining adequate talent. The ... -
The Nonprofit Sector's Involvement In Prisoner Reentry : A Mixed Methods Analysis
(Urban & Public Affairs, 2013-07-22)The 1990's were plagued with crime and high recidivism rates, and the State of Texas responded by embarking upon the largest expansion of a criminal justice system in its history. Having served their sentences, record ... -
Nonrigid Image Registration By The Deformation Based Grid Generation
(Computer Science & Engineering, 2009-09-16)A novel nonrigid image registration algorithm is developed using a well-established mathematic work known as deformation based grid generation. The deformation based grid generation is capable to generate a grid ... -
NONUPDATING METHODS FOR THE CHARACTERIZATION OF NONLINEAR STRESS-STRAIN AND DELAMINATION FRACTURE PROPERTIES OF FIBER REINFORCED COMPOSITES
(2018-12-07)Efforts to develop strength and life prediction analysis tools for aircraft composite structures have shown a great need to understand the complexity and interaction of failure modes. Many failure models are highly sensitive ... -
NORMALIZED CUT PROBLEMS WITH GENERALIZED LINEAR CONSTRAINTS
(2019-08-30)Several methods are used to process images in many fields, including clustering, image segmentation and medical imaging. The so-called graph-cut methods in graph theory are widely used for image segmentation. In these ... -
The North Texas Aerospace Manufacturing And Aviation Industries: An Explanatory Case Study Of School-to-work Collaborative Networks
(Education, 2014-12)The purpose of this study is to explore how educators, business partners and facilitators developed ties or networks to initiate a school-to-work collaboration to prepare students for jobs and careers in the aerospace ... -
North Texas Stakeholders: Perceptions Of Extensive Green Roofs
(Landscape Architecture, 2010-03-03)Green roofs are not a new technology. The first recorded green roof was the Hanging Gardens of Babylon built by King Nebuchadnezzar for his wife Amyitis who missed her lush homeland (Osmundson 1999). However, since the ... -
