Was geh{\"o}rt aber zu einem "Transformationsprojekt", welche Prozesse und Systeme werden ver{\"a}ndert? Zur Beantwortung dieser Frage haben wir 184 Berichte zu Projekten analysiert, die als "Transformationsprojekte" bezeichnet waren. F{\"u}r die Analyse haben wir einen Kodierungsrahmen konzipiert und anhand dessen die Berichte mit einem hierarchischen Clustering-Verfahren in Themen gruppiert. Die Ergebnisse liefern Hinweise {\"u}ber die in der Praxis gesetzten Schwerpunkte und Priorit{\"a}ten. Sie k{\"o}nnen somit als Unterst{\"u}tzung f{\"u}r Unternehmen dienen, die ein Transformationsprojekt planen.

Increased competition, short innovation cycles, changed usage patterns, increased customer expectations and cost reduction are the main drivers. Our objective is to analyze to what extend transformation projects have improved the orientation towards the end-customers. Therefore, we selected 38 real-life case studies that are dealing with customer orientation. Our analysis is based on a telecommunication-specific framework that aligns strategy, business processes and information systems. The result of our analysis shows the following: transformation projects that aim to improve the customer orientation are combined with clear goals on costs and revenue of the enterprise. These projects are usually directly linked to the customer touch points, but also to the development and provisioning of products. Furthermore, the analysis shows that customer orientation is not the sole trigger for transformation. There is no one-fits-all solution; rather, improved customer orientation needs aligned changes of business processes as well as information systems related to different parts of the company.}, language = {en} } @inproceedings{Czarnecki2011, author = {Czarnecki, Christian}, title = {Gestaltung von Customer Relationship Management {\"u}ber die Grenzen von Telekommunikationsunternehmen hinweg}, series = {Tagungsband zum Doctoral Consortium der WI 2009}, booktitle = {Tagungsband zum Doctoral Consortium der WI 2009}, editor = {Eymann, Torsten}, publisher = {Universit{\"a}t Bayreuth Lehrstuhl f{\"u}r Wirtschaftsinformatik}, address = {Bayreuth}, issn = {1864-9300}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:703-opus-5462}, pages = {11 -- 23}, year = {2011}, abstract = {Durch die Fragmentierung von Wertsch{\"o}pfungsketten ergeben sich neue Herausforderungen f{\"u}r das Management von Kundenbeziehungen.

Although the implementation of an NGN seems to be merely a modification of the network infrastructure, it may trigger or require changes in the whole company and even influence the company strategy. To capture the effects of NGN we propose a framework based on concepts of business engineering and technical recommendations for the introduction of NGN technology. The specific design of solutions for the layers "Strategy", "Processes" and "Information Systems" as well as their interdependencies are an essential characteristic of the developed framework. We have per-formed a case study on NGN implementation and observed that all layers captured by our framework are influenced by the introduction of an NGN.}, language = {en} } @inproceedings{HeuermannSadeghfam2016, author = {Heuermann, Holger and Sadeghfam, Arash}, title = {Analog Amplitude-Locked Loop Circuit to Support RF Energy Solutions}, series = {IEEE MTT-S International Microwave Symposium Digest}, booktitle = {IEEE MTT-S International Microwave Symposium Digest}, isbn = {978-150900698-4}, doi = {10.1109/MWSYM.2016.7540092}, pages = {4 Seiten}, year = {2016}, language = {de} } @inproceedings{StopforthDavrajhFerrein2017, author = {Stopforth, Riaan and Davrajh, Shaniel and Ferrein, Alexander}, title = {South African robotics entity for a collaboration initiative}, series = {Pattern Recognition Association of South Africa and Robotics and Mechatronics International Conference (PRASA-RobMech), 2016}, booktitle = {Pattern Recognition Association of South Africa and Robotics and Mechatronics International Conference (PRASA-RobMech), 2016}, publisher = {IEEE}, isbn = {978-1-5090-3335-5}, doi = {10.1109/RoboMech.2016.7813144}, pages = {1 -- 6}, year = {2017}, language = {en} } @inproceedings{WalentaSchellekensFerreinetal.2017, author = {Walenta, Robert and Schellekens, Twan and Ferrein, Alexander and Schiffer, Stefan}, title = {A decentralised system approach for controlling AGVs with ROS}, series = {AFRICON, Proceedings}, booktitle = {AFRICON, Proceedings}, publisher = {IEEE}, isbn = {978-1-5386-2775-4}, issn = {2153-0033}, doi = {10.1109/AFRCON.2017.8095693}, pages = {1436 -- 1441}, year = {2017}, language = {en} } @inproceedings{NiemuellerNeumannHenkeetal.2017, author = {Niemueller, Tim and Neumann, Tobias and Henke, Christoph and Sch{\"o}nitz, Sebastian and Reuter, Sebastian and Ferrein, Alexander and Jeschke, Sabina and Lakemeyer, Gerhard}, title = {International Harting Open Source Award 2016: Fawkes for the RoboCup Logistics League}, series = {RoboCup 2016: RoboCup 2016: Robot World Cup XX.

Here, the power of the device under test (DUT) ranges from some Watts to a few hundred Watts. The torque and speed of the DUT are measured independent of voltage and current in multiple load points. A Matlab-based software approach in combination with an open Texas-Instruments (TI) hardware setup ensures flexibility. Exemplarily, the efficiency field of a Permanent Magnet Synchronous Machine (PMSM) is measured to proof the concept. Brushless-DC (BLDC) motors can be tested as well. The nomenclature in this paper is based on the new European standard DIN EN 50598. Special attention is paid to the calculation of the measurement error.}, language = {en} }
