The aim of Reverse Engineering is to convert an unstructured representation of a geometric object, emerging e.g. from laser scanners, into a natural, structured representation in the spirit of CAD models, which is suitable for numerical computations. Therefore we present a user-controlled, as isometric as possible parameterization technique which is able to prescribe geometric features of the i...

This paper studies global adaptive control of nonlinearly parameterized systems with uncontrollable linearization. Using a new parameter separation technique and the tool of adding a power integrator, we develop a feedback domination design approach for the explicit construction of a smooth adaptive controller that solves the problem of global state regulation. In contrast to the existing resul...

This paper summarizes the formulation of the ocean component to the Geophysical Fluid Dynamics Laboratory’s (GFDL) climate model used for the 4th IPCC Assessment (AR4) of global climate change. In particular, it reviews the numerical schemes and physical parameterizations that make up an ocean climate model and how these schemes are pieced together for use in a state-of-the-art climate model. F...

This paper proposes and compares different methods of representing the primary color tone reproduction curves (TRC) for the stabilization control in a color xerographic printing process. TRC stabilization is vital in maintaining high consistency in color printout. Colors are typically represented by a 3-dimensional representation such as the CIELAB or CIEXYZ colorspaces. For stabilization contr...

in this paper, a novel approach for control of the dc-dc buck converter in high-power and low-voltage applications is proposed. designed method is developed according to state feedback linearization based controller , which is able to stabilize output voltage in a wide range of operation. it is clear that in high-power applications, parasitic elements of the converter may become comparable with...

Parameterization is the key property of a parametric surface and significantly affects many kinds applications. To improve quality parameterization, equiareal parameterization minimizes energy, which presented as measure to describe uniformity iso-parametric curves. With help binary Möbius transformation, extended triangular Bézier on domain for first time. The solution corresponding nonlinear ...

This paper presents a new parameterization for shear-driven, stratified, turbulent mixing that is pertinent to climate models, in particular the shear-driven mixing in overflows and the Equatorial Undercurrent. This parameterization satisfies a critical requirement for climate applications by being simple enough to be implemented implicitly and thereby allowing the parameterization to be used w...

In this article, a recursive set-membership filtering algorithm for discrete-time nonlinear dynamical systems subject to unknown but bounded process and measurement noises is proposed. The dynamics are represented in pseudolinear form using the state-dependent coefficient (SDC) parameterization. Matrix Taylor expansions utilized expand matrices about state estimates. Upper bounds on norms of re...
