Multiobjective H_2/H_infinity-optimal control via finite dimensional Q-parametrization and linear matrix inequalities
Controller design convex semidefinite programming impulse response
2015/8/11
The problem of multi-objective H2/H-infinity optimal controller design is reviewed. There is as yet no exact solution to this problem. We present a method based on that proposed by Scherer. The proble...

Information Constraints Parametrization
2015/6/19
We present a generalization of the Youla parametrization for discrete-time nonlinear systems, and give conditions when a constrained set of controllers and a set of Youla parameters correspond to each...

for small-scale modelling”) model.
Coupling a new turbulence parametrization to RegCM adds realistic stratocumulus clouds
turbulence parametrization RegCM adds realistic stratocumulus
2014/12/10
To model stratocumulus clouds in the regional climate model, RegCM4.1, the University of Washington (UW)
turbulence parametrization has been coupled to RegCM. We
describe improvements in RegCM’s coa...
Phase space parametrization of rain: the inadequacy of the gamma distribution
Phase space parametrization of rain the inadequacy of gamma distribution
2012/11/23
We show that the Gamma distribution is not an adequate fit for the probability density function of drop diameters using the Kolmogorov-Smirnov goodness of fit test. We propose a different parametrizat...
Constraining dynamical dark energy with a divergence-free parametrization in the presence of spatial curvature and massive neutrinos
Constraining dynamical dark energy divergence-free parametrization presence spatial curvature massive neutrinos
2012/2/21
In this paper, we report the results of constraining the dynamical dark energy with a divergence-free parameterization, $w(z) = w_{0} + w_{a}(\frac{\ln(2+z)}{1+z}-\ln2)$, in the presence of spatial cu...
Approximate Parametrization of Space Algebraic Curves
Approximate Parametrization Space Algebraic Curves Algebraic Geometry
2011/8/30
Abstract: Given a non-rational real space curve and a tolerance $\epsilon>0$, we present an algorithm to approximately parametrize the curve. The algorithm checks whether a planar projection of the sp...
Comparing partial-wave amplitude parametrization with dynamical models of meson-nucleon scattering
partial-wave amplitude parametrization dynamical models meson-nucleon scattering Nuclear Theory
2011/10/11
Abstract: Relationships between partial-wave amplitude parametrizations, in particular the Chew-Mandelstam approach, and dynamical coupled-channel models are established and investigated. A bare pole ...
Radial extension of a bi-Lipschitz parametrization of a starlike Jordan curve
Radial extension bi-Lipschitz parametrization
2010/11/24
In this paper we discus the radial extension $w$ of a bi-Lipschitz parameterization $F(e^{it})=f(t)$ of a starlike Jordan curve $\gamma$ w.r. to $0$. We show that, if parameterization is bi-Lipschitz,...
A parametrization of the abstract Ramsey theorem
parametrization the abstract Ramsey theorem
2010/11/23
We give a parametrization with perfect subsets of $2^{\infty}$ of the abstract Ramsey theorem (see \cite{todo}) Our main tool is an extension of the parametrized version of the combinatorial forcing d...
Optimal bounded trigonometry control of N-level quantum systems based on the geometrical parametrization
Optimal bounded trigonometry control N-level quantum systems based geometrical parametrization
2010/11/5
Based on the observation that the pure states of $N-$level quantum systems can be expressed in terms of $2(N-1)$ real geometric parameters, we make full use of distinguished properties of generalized ...

Algorithms Del Pezzo Surfaces of Degree 5
2010/12/9
It is well known that every Del Pezzo surface of degree 5 defined over k is parametrizable over k. In this paper we give an efficient construction for parametrizing, as well as algorithms for construc...

2010/3/9
We study a class of parametrizations of convex cones of positive
semidefinite matrices with prescribed zeros. Each such cone corresponds to
a graph whose non-edges determine the prescribed zeros. Ea...
