To achieve an optimal operating condition, a good characterization of the lamp in terms of radio frequency equivalent circuits under operating conditions is necessary, enabling the design of an efficient matching network. This paper presents the characterization technique for such lamps and presents the design of the required matching network. For the characterization, a high-intensity discharge lamp was driven by a monofrequent large signal at 2.45 GHz, whereas a frequency sweep over 300 MHz was performed across this signal to measure so-called small-signal hot S-parameters using a vector network analyzer. These parameters are then used as an equivalent load in a circuit simulator to design an appropriate matching network. Using the measured data as a black-box model in the simulation results in a quick and efficient method to simulate and design efficient matching networks in spite of the complex plasma behavior. Furthermore, photometric analysis of high-intensity discharge lamps are carried out, comparing microwave operation to conventional operation.}, language = {en} } @incollection{NiemuellerEwertReuteretal.2014, author = {Niem{\"u}ller, Tim and Ewert, Daniel and Reuter, Sebastian and Ferrein, Alexander and Jeschke, Sabina and Lakemeyer, Gerhard}, title = {RoboCup logistics league sponsored by festo: A competitive factory automation testbed}, series = {RoboCup 2013: Robot World Cup XVII : Eindhoven; Netherlands; 1 July 2013 through 1 July 2013.

The novel RoboCup Logistics League Sponsored by Festo (LLSF) aims at such CPS logistic scenarios in an automation setting. A team of robots has to produce products from a number of semi-finished products which they have to machine during the game. Different production plans are possible and the robots need to recycle scrap byproducts. This way, the LLSF is a very interesting league offering a number of challenging research questions for planning, coordination, or communication in an application-driven scenario. In this paper, we outline the objectives of the LLSF and present steps for developing the league further towards a benchmark for logistics scenarios for CPS. As a major milestone we present the new automated referee system which helps in governing the game play as well as keeping track of the scored points in a very complex factory scenario.}, language = {en} } @article{AlhwarinFerreinScholl2014, author = {Alhwarin, Faraj and Ferrein, Alexander and Scholl, Ingrid}, title = {IR stereo kinect: improving depth images by combining structured light with IR stereo}, pages = {1 -- 9}, year = {2014}, language = {en} } @book{Huening2014, author = {H{\"u}ning, Felix}, title = {The fundamentals of electrical engineering for mechatronics}, publisher = {de Gruyter}, address = {Berlin}, isbn = {978-3-11-034991-7 (Druckausg.)}, pages = {IX, 208 S.}, year = {2014}, language = {en} } @article{Ferrein2008, author = {Ferrein, Alexander}, title = {Towards applying soccer moves in the RoboCup Standard Platform League}, series = {{\"O}GAI-Journal}, volume = {Bd. 27}, journal = {{\"O}GAI-Journal}, number = {H. 3}, organization = {{\"O}sterreichische Gesellschaft f{\"u}r Artificial Intelligence}, issn = {0254-4326}, pages = {4 -- 9}, year = {2008}, language = {en} } @book{FerreinPauliSiebeletal.2009, author = {Ferrein, Alexander and Pauli, J. and Siebel, N.
