Revisiting Consensus-Based Energy-Management in Smart Grid with Transmission Losses and Directed Communication
Jan Zimmermann, Tatiana Tatarenko, Volker Willert +1
We discovered a deficiency in Algorithm 1 and Theorem 3 of [1]. The algorithm called CEMA aims to solve an energy management problem distributively. However, by means of a counter…
Projected Push-Sum Gradient Descent-Ascent for Convex Optimizationwith Application to Economic Dispatch Problems
Jan Zimmermann, Tatiana Tatarenko, Volker Willert +1
We propose a novel algorithm for solving convex, constrained and distributed optimization problems defined on multi-agent-networks, where each agent has exclusive access to a part…
Some Aspects of Geometric Computer Vision for Analysing Dynamical Scenes focusing Automotive Applications
Volker Willert, Martin Buczko
This draft summarizes some basics about geometric computer vision needed to implement efficient computer vision algorithms for applications that use measurements from at least one…
Train-borne Localization Exploiting Track-Geometry Constraints -- A Practical Evaluation
Hanno Winter, Volker Willert, Jürgen Adamy
Today's railway signalling system heavily relies on trackside infrastructure such as axle counters and track balises. This system has proven itself to be reliable, however, it is n…
Penalized Push-Sum Algorithm for Constrained Distributed Optimization with Application to Energy Management in Smart Grid
Tatiana Tatarenko, Jan Zimmermann, Volker Willert andJürgen Adamy
We study distributed convex constrained optimization on a time-varying multi-agent network. Each agent has access to its own local cost function, its local constraints, and its ins…
Generating Compact Geometric Track-Maps for Train Positioning Applications
Hanno Winter, Stefan Luthardt, Volker Willert +1
In this paper, we present a method to generate compact geometric track-maps for train-borne localization applications. Therefore, we first give a brief overview on the purpose of t…
