Title of Document: STABILIZATION OF MHD TURBULENCE BY APPLIED STEADY AND OSCILLATING VELOCITY SHEAR Ching Pui HUNG, Doctor of Philosophy, 2013 Dissertation Directed By: Professor Adil B. Hassam, Department of Physics Some aspects of velocity shear stabilization of magnetized plasma instabilities are considered. In the first part, steady externally forced flow shears are considered. In the secon...

Generalized additive models represented using penalized regression splines, estimated by penalized likelihood maximisation and with smoothness selected by generalized cross validation or similar criteria, provide a computationally efficient general framework for practical smooth modelling. Various authors have proposed approximate Bayesian interval estimates for such models, based on extensions...

Pansy (Viola × wittrockiana Gams.) is an important and attractive ornamental plant with a wide variety of flower colors. To date, the molecular genetic understanding its colorful petal pigment patterns remains largely unknown. In this study, we analyzed bicolor petals “Mengdie” in cytological, physiological, transcriptomic aspects. Results showed that difference colors was mainly determined by ...

This article presents a methodology to optimize the maintenance planning model and minimize total costs of typical school building. It makes an effort provide schedule, focusing on costs. In allocation operations equipment, parameter its age was also taken into account. A mathematical optimization cost in three-year period provided GAMS software with CPLEX solver. Finally, optimum architecture ...

This paper proposes an interconnection of the MATLAB and GAMS software interfaces, which were designed based on a master-slave methodology, to solve mixed-integer nonlinear programming (MINLP) model problem associated with regarding optimal location sizing static distribution compensators (D-STATCOMs) in meshed radial networks, considering reactive power flow compensation fact that networks hav...

The paper describes a new computerized collection of test models for mixed-integer nonlinear programming. Since there is no standard format for nonlinear models, the model collection is augmented with a translation server that can transform the models from their basic GAMS format into a number of other formats such as AMPL, BARON, LINGO, and MINOPT. The translation server can also be used to tr...

In this paper, an uninterrupted hybrid flow scheduling problem is modeled under uncertainty conditions. Due to the of processing time in workshops, fuzzy programming method has been used control parameters and preparation time. proposed model, there are several jobs that must be processed by machines workers, respectively. The main purpose model determine correct sequence operations assign each...

This paper presents a novel approach to tackle the problem of optimal neutral wire grounding in bipolar DC networks including asymmetric loading, which naturally involves mixed-integer nonlinear programming (MINLP) and is challenging solve. MINLP model transformed into recursive quadratic (MIQ) by linearizing hyperbolic relation between voltage powers constant power terminals. A algorithm imple...
