Distributed Manufacturing -
Eine Technologievorausschau anhand IT-gestützter bibliometrischer Analyse und Szenariotechnik
Bericht
(Universität Ulm, 2017-05-31)
Im Zuge der vierten industriellen Revolution eröffnen sich durch die zunehmende Konnektivität und neue Technologien, insbesondere Fertigungsverfahren wie der 3D-Druck, neue Wertschöpfungsprozesse in der Produktion. Das ...
Exchangeability of copulas
Dissertation
(Universität Ulm, 2016-07-08)
When studying the dependence structure of multivariate random vectors, the copula is crucial. A copula is called exchangeable, if it is invariant under any permutation of its arguments. In this thesis, a limit for the ...
Nichtlineare partielle Differentialgleichungen vom gemischten elliptisch-hyperbolischen Typ
Dissertation
(Universität Ulm, 2017-08-28)
This thesis studies the article "Local solutions to a class of Monge-Ampère equations of mixed type" by Qing Han (Duke Math. J., Vol. 136, No. 3, 2007). The article proves the existence of sufficiently smooth local solutions ...
Cycle decompositions and t-perfect graphs
Dissertation
(Universität Ulm, 2017-10-18)
The thesis is divided into two parts. The first part deals with t-perfect graphs. A graph is called t-perfect if its stable set
polytope is fully described by non-negativity, edge and odd-cycle constraints. We give ...
Hebbarkeit singulärer Mengen der m-Hesse-Gleichungen
Dissertation
(Universität Ulm, 2017-11-06)
In dieser Arbeit geben wir eine neue, weniger restriktive Forderung für die Hebbarkeit singulärer Mengen E von glatten Lösungen der m-Hesse Gleichung (und auch für allgemeinere nichtlineare elliptische Gleichungen) auf ...
Reduced-basis method (RBM) for non-affine elliptic parametrized PDEs - (motivated by optimization in hydromechanics)
Dissertation
This work has been motivated by optimizing the efficiency of a ship-propulsion device, the Voith-Schneider Propeller, w.r.t. its steering (determined by the so-called blade-steering curve). We consider a simplified model ...
Unconditional and conditional institutional effects on unemployment: a Bayesian model averaging approach
Dissertation
Labor and product market institutions are regarded as central factors for explaining differences in the evolution of unemployment across countries. It is generally assumed that reforms which serve to reduce institutional ...
Estimation and optimization problems in power markets
Dissertation
Die vorliegende Arbeit gliedert sich in zwei Hauptteile. Der erste Teil beschreibt und analysiert ein Modell, welches das Ziel hat die gleichzeitige Entwicklung von Elektrizitäts- und Gaspreisen möglichst adäquat abzubilden. ...
Characteristics of Poisson cylinder processes and their estimation
Dissertation
In this thesis, we consider stationary Poisson cylinder processes (PCPs). Here, a cylinder is defined as the Minkowski sum of a linear vectorspace and a polyconvex set in the orthogonal space. A PCP is a random set of ...
Betweenness relations
Dissertation
This thesis primarily gives an overview of research on so called betweenness relations with a focus on own contributions to that subject.
Betweenness relations represent a generalisation of the geometric notion that one ...
