Optimal designs for estimating pairs of coefficients in Fourier regression models [PDF]
, 2008 In the common Fourier regression model we investigate the optimal design problem for estimating pairs of the coefficients, where the explanatory variable varies in the interval [¡¼; ¼].

Satisficing Newsvendor Problem with the Optimism Coefficient [PDF]
Foundations of Computing and Decision Sciences, 2019 Abstract In this research note the satisficing newsvendor problem is considered which is defined as the maximization of the probability of exceeding the expected profit multiplied by a positive constant. This constant called optimism coefficient can be chosen by the firm’s management either based on their preference or the market ...

Two Inverse Problems Solution by Feedback Tracking Control
Axioms, 2021 Two inverse ill-posed problems are considered. The first problem is an input restoration of a linear system. The second one is a restoration of time-dependent coefficients of a linear ordinary differential equation.

Determination of optimal nudging coefficients [PDF]
Tellus A: Dynamic Meteorology and Oceanography, 2003 A four-dimensional variational assimilation (4D-Var) scheme is now widely used by meteorological centres in a operational way. However, most of these applications do not take account of model error. Indeed, the classical 4D-Var with imperfect model formulation is unaffordable for current computational means.

On the optimal regularity of coefficients in hyperbolic Cauchy problems
Bulletin des Sciences Mathématiques, 2003 The authors consider the Cauchy problem for a second-order hyperbolic equation \[ \begin{gathered} u_{tt}(t, x)- a(t) u_{xx}(t, x)+ b(t) u_x(t, x)= 0,\quad [0, T]\times \mathbb{R}^n,\\ u(0, x)= \phi(x),\quad u_t(0, x)= \psi(x).\end{gathered} \] They prove that if the coefficients \(a(t)> 0\) and \(b(t)\) satisfy \[ \begin{alignedat}{2} |\partial^k_t a ...
