However, such asymmetric tensors are usually symmetrized and then further processed. Using this procedure results in a loss of information. A new method for the processing of asymmetric tensor fields is proposed restricting our attention to tensors of second-order given by a 2x2 array or matrix with real entries. This is achieved by a transformation resulting in Hermitian matrices that have an eigendecomposition similar to symmetric matrices. With this new idea numerical results for real-world data arising from a deformation of an object by external forces are given. It is shown that the asymmetric part indeed contains valuable information.}, language = {en} } @inproceedings{FredebeulKrein2016, author = {Fredebeul-Krein, Markus}, title = {Towards trade facilitation via regulatory convergence: An analysis of the TTIP chapter on Electronic Communications}, series = {Regional ITS Conference of the International Telecommunications Society.

Cambridge, United Kingdom, 7-9 September 2016}, pages = {29 Seiten}, year = {2016}, abstract = {To give the exchange of goods and services between the European Union (EU) and the United States (U.S.) new momentum the two parties are currently negotiating the transatlantic free trade agreement Transatlantic Trade and Investment Partnership (TTIP). The aim is to create the largest free trade area in the world. The agreement, once entered into force, will oblige EU countries and the U.S. to further liberalize their markets. The negotiations on TTIP include a chapter on Electronic Communications/ Telecommunications. The challenge therein will be securing commitments for market access to Electronic Communications services. At the same time, these commitments must reflect the legitimate need for consumer protection issues. The need to reduce Electronic Communications-related non-tariff barriers to trade between the Parties is due to the fact that these markets are heavily regulated. Without transnational rules as to regulations national governments can abuse these regulations to deter the market entry by new (foreign) suppliers. Thus the free trade agreement TTIP affects in many respects regulatory provisions on and access to Electronic Communications markets. The objective of this paper is therefore to examine to what extend the regulatory principles for Electronic Communications markets envisaged under TTIP will result in trade facilitation and regulatory convergence between the EU and the U.S. As to this question the result of the analysis is that the chapter on Electronic Communications will be an important step towards facilitating trade in Electronic Communications services. At the same time some regulatory convergence will take place, but this convergence will not lead to a (full) harmonization of regulations. Rather the norm, also after TTIP negotiations will have been concluded successfully, will be mutual recognition of different regulatory regimes. Different regulations being the optimal policy response in different market settings will continue to exist. Moreover, it is very unlikely that such regulatory principles for the Electronic Communications sector are a vehicle for a race to the bottom in levels of consumer protection.}, language = {en} } @article{RaabKappelKraemeretal.2011, author = {Raab, Monika and Kappel, Sven and Kr{\"a}mer, Andrea and Sanhaji, Mourad and Matthess, Yves and Kurunci-Csacsko, Elisabeth and Calzada-Wack, Julia and Rathkolb, Birgit and Rosman, Jan and Adler, Thure and Busch, Dirk H. and Esposito, Irene and Fuchs, Helmut and Gailus-Durner, Val{\´e}rie and Klingenspor, Martin and Wolf, Eckhard and S{\"a}nger, Nicole and Prinz, Florian and Hrabe de Angelis, Martin and Seibler, Jost and Yuan, Juping and Bergmann, Martin and Knecht, Rainald and Kreft, Bertolt and Strebhardt, Klaus}, title = {Toxicity modelling of Plk1-targeted therapies in genetically engineered mice and cultured primary mammalian cells}, series = {Nature Communications}, volume = {2}, journal = {Nature Communications}, number = {395}, publisher = {Nature}, address = {London}, issn = {2041-1723}, doi = {10.1038/ncomms1395}, pages = {1 -- 11}, year = {2011}, language = {en} } @article{GlueckSchoeningLuethetal.1999, author = {Gl{\"u}ck, O. and Sch{\"o}ning, Michael Josef and L{\"u}th, H. and Otto, A. and Emons, H.}, title = {Trace metal determination by dc resistance changes of microstructured thin gold film electrodes}, series = {Electrochimica Acta. 44 (1999), H. 21-22}, journal = {Electrochimica Acta. 44 (1999), H. 21-22}, isbn = {0013-4686}, pages = {3761 -- 3768}, year = {1999}, language = {en} } @article{GlueckSchoeningLuethetal.1997, author = {Gl{\"u}ck, O. and Sch{\"o}ning, Michael Josef and L{\"u}th, H. and Emons, H. and Hanewinkel, C. and Schumacher, D. and Otto, A.}, title = {Trace metal determination with gold microelectrodes fabricated by silicon technology}, series = {Proceedings of the 11th European Conference on Solid-State Transducers / Eurosensors XI, September 21 - 24, 1997, Warsaw, Poland.

This not only makes it difficult to trace them back but also leaves room for criminal organizations to fake them unnoticed. For these reasons, it is becoming increasingly difficult to determine the exact origin of drugs. The goal of this work was to investigate how exactly this is possible by using different spectroscopic methods like nuclear magnetic resonance and near- and mid-infrared spectroscopy in combination with multivariate data analysis. As an example, 56 out of 64 different paracetamol preparations, collected from 19 countries around the world, were chosen to investigate whether it is possible to determine the pharmaceutical company, manufacturing site, or country of origin. By means of suitable pre-processing of the spectra and the different information contained in each method, principal component analysis was able to evaluate manufacturing relationships between individual companies and to differentiate between production sites or formulations. Linear discriminant analysis showed different results depending on the spectral method and purpose. For all spectroscopic methods, it was found that the classification of the preparations to their manufacturer achieves better results than the classification to their pharmaceutical company. The best results were obtained with nuclear magnetic resonance and near-infrared data, with 94.6\%/99.6\% and 98.7/100\% of the spectra of the preparations correctly assigned to their pharmaceutical company or manufacturer.}, language = {en} } @article{SanderFidlerKlimala2005, author = {Sander, Volker and Fidler, Markus and Klimala, Wojciech}, title = {Traffic shaping in aggregate-based networks: implementation and analysis / Fidler, Markus ; Sander, Volker ; Klimala, Wojciech}, series = {Computer Communications. 28 (2005), H. 3}, journal = {Computer Communications. 28 (2005), H. 3}, isbn = {0140-3664}, pages = {274 -- 286}, year = {2005}, language = {en} } @inproceedings{SteuerDankert2023, author = {Steuer-Dankert, Linda}, title = {Training future skills - sustainability, interculturality \& innovation in a digital design thinking format}, series = {Proceedings of the 19th International CDIO Conference}, booktitle = {Proceedings of the 19th International CDIO Conference}, pages = {12 Seiten}, year = {2023}, abstract = {The complex questions of today for a world of tomorrow are characterized by their global impact. Solutions must therefore not only be sustainable in the sense of the three pillars of sustainability (economic, environmental, and social) but must also function globally. This goes hand in hand with the need for intercultural acceptance of developed services and products. To achieve this, engineers, as the problem solvers of the future, must be able to work in intercultural teams on appropriate solutions, and be sensitive to intercultural perspectives. To equip the engineers of the future with the so-called future skills, teaching concepts are needed in which students can acquire these methods and competencies in application-oriented formats. The presented course "Applying Design Thinking - Sustainability, Innovation and Interculturality" was developed to teach future skills from the competency areas Digital Key Competencies, Classical Competencies and Transformative Competencies. The CDIO Standard 3.0, in particular the standards 5, 6, 7 and 8, was used as a guideline. The course aims to prepare engineering students from different disciplines and cultures for their future work in an international environment by combining a digital teaching format with an interdisciplinary, transdisciplinary and intercultural setting for solving sustainability challenges. The innovative moment lies in the digital application of design thinking and the inclusion of intercultural as well as trans- and interdisciplinary perspectives in innovation development processes. In this paper, the concept of the course will be presented in detail and the particularities of a digital implementation of design thinking will be addressed. Subsequently, the potentials and challenges will be reflected and practical advice for integrating design thinking in engineering education will be given.}, language = {en} } @inproceedings{KobGoemmelButenwegetal.2006, author = {Kob, Malte and G{\"o}mmel, Andreas and Butenweg, Christoph and Niendorf, Thoralf}, title = {Training of a combined model of larynx and vocal folds with data from MRI measurements}, series = {The 5th International Conference on Voice Physiology and Biomechanics: Variations across Cultures and Species, July 12-14, 2006, Tokyo, Japan.
