2005-11-16BuchOn asymptotics in case of linear index-2 differential-algebraic equations Asymptotic properties of solutions of general linear differential-algebraic equations (DAE's) and those of their numerical counterparts are discussed. New results on the asymptotic stability in the sense of Lyapunov as ...

2021-07-08ZeitschriftenartikelOn coalitional manipulation for multiwinner elections: shortlisting Shortlisting of candidates—selecting a group of “best” candidates—is a special case of multiwinner elections. We provide the first in-depth study of the computational complexity of strategic voting for shortlisting based ...

2016-04-20KonferenzveröffentlichungOn Computation and Application of k Most Locally-Optimal Paths in Road Networks For some applications, e.g. route planning services, it is desirable to answer a point-to-point shortest path query on a road network with a set of alternative paths. We discuss the general requirements for such sets ...

2016-04-20KonferenzveröffentlichungOn Context-Aware Communication Mode Selection in Hybrid Vehicular Networks Future vehicles will most-likely have multiple communication technologies and modes available. After classifying V2X applications in five distinct classes, a context-aware selection of the communication mode is advocated. ...

1998-11-03BuchOn Convolution Operators in the Spaces of Almost Periodic Functions and Lp Spaces We consider operators of convolution generated by $L^1$ functions in $L^p$ and various spaces of almost periodic functions. It turns out to be that if such an operator is invertible in one of these spaces, then it is ...

2004-09-13BuchOn deviation measures in stochastic integer programming We propose extensions of traditional expectation-based stochastic integer programs to mean-risk models. Risk is measured by expected deviations of suitable random variables from their means or from preselected targets. We ...
-
2005-11-14BuchOn Differentiability of Metric Projections onto Moving Convex Sets We consider properties of the metric projections onto moving convex sets in normed linear spaces. Under certain conditions about the norm, directional differentiability (of higher order) of the metric projections at boundary ...

2014-05-07BuchOn Distributionally Robust Multiperiod Stochastic Optimization This paper considers model uncertainty for multistage stochastic programs. The data and information structure of the baseline model is a tree, on which the decision problem is defined. We consider ambiguity neighborhoods ...
-
1999-05-24BuchOn double one-parametric optimization problems and some applications This paper deals with a special class of quadratic optimization problems with quadratic constraints, which we call double parametric. We try to solve these problems using Pathfollowing Methods with a special case of the ...

2009-10-29DiskussionspapierOn economic evaluation of directional forecasts It is commonly accepted that information is helpful if it can be exploited to improve a decision mak- ing process. In economics, decisions are often based on forecasts of up{ or downward movements of the variable of interest. ...

2016-11-14DissertationOn efficient a posteriori error analysis for variational inequalities Effiziente und zuverlässige a posteriori Fehlerabschätzungen sind eine Hauptzutat für die effiziente numerische Berechnung von Lösungen zu Variationsungleichungen durch die Finite-Elemente-Methode. Die vorliegende Arbeit ...

2006-03-16BuchOn Estimating a dynamic function of a stochastic system with averaging We consider a two-scaled diffusion system, when drift and diffusion parameters of the “slow” component are contaminated by the “ fast” unobserved component. The goal is to estimate the dynamic function which is defined by ...

2023-07-19MasterarbeitOn Estimating Causal Effects in Poisson-based Density Regression with an Application to the Retirement-Consumption Puzzle Diese Arbeit beschäftigt sich mit der Schätzung kausaler Effekte im Kontext von Dichteregression insbesondere mit der Schätzung des kausalen Effektes des Renteneintritts auf die Höhe der Konsumausgaben. In früheren Studien ...

1997-08-01BuchOn Estimation of Monotone and Concave Frontier Functions When analyzing the productivity of firms, one may want to compare how the firms transform a set of inputs x (typically labor, energy or capital) into an output y (typically a quantity of goods produced). The economic ...

2011-08-11BuchOn Existence and Regularity of Solutions for a Stationary Navier-Stokes System Coupled to an Equation for the Turbulent Kinetic Energy We investigate a stationary model for turbulent flows, in which the Navier-Stokes system is coupled to an equation for the density of turbulent kinetic energy through a bounded coefficient of eddy viscosity. We prove the ...
