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...
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...
A new snow melting parametrization is presented for the non-hydrostatic limitedarea COSMO (“consortium for small-scale modelling”) model.
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...
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...
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...
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...
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,...
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...
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 ...
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...
The Casas-Ibarra parametrization is a description of the Dirac neutrino mass matrix MD in terms of the neutrino mixing matrix V, an orthogonal matrix O and the diagonal mass matrices of light and heav...
Atmospheric new particle formation is a general phenomenon observed over coniferous forests. So far nucleation is either parameterised as a function of gaseous sulphuric acid concentration only, which...
A duo two-dimensional deterministic model of contaminant transport through a homogeneous and anisotropic unconfined aquifer is developed. This model is then utilized to evaluate the effects of such ...
A sea-ice model is used to investigate the ice-ocean heat flux that occurs at the base of the ice. The source of this basal heat flux is supposed in reality to arise from physical processes (e.g. ocea...
