It is based on the combination of software metrics data with structure information to form a virtual information space. This information space is visualized using 3D graph structures that allow to represent in a uniform way many aspects and views on it. The layout approach for these graphs uses a generic similarity measure to calculate geometric distances between the graph nodes and a force-directed mapping into 3D space. A particular strength of the approach is that the resulting geometrical structures can be well interpreted with respect to the architecture and design quality of the analysed software. Such 3D visualizations have been used successfully in several case studies for the quality assessment of industrial C++/Java projects.}, language = {en} } @inproceedings{GruenewaldIpsenKaltofenetal., author = {Gr{\"u}newald, Uwe and Ipsen, Detlev and Kaltofen, Michael and Karkuschke, Matthias and Koch, Hagen and Messner, Frank and Schramm, Michael and Schuster, Steffi and Simon, Karl-Heinz and Wehrle, Astrid and Zwirner, Oliver}, title = {Sustainable Water Resources Management and Regional Development in the Upper Spree River Basin Heavily Influenced by Lignite Open Pit Mining}, publisher = {GSF Forschungszentrum f{\"u}r Umwelt und Gesundheit}, language = {de} } @inproceedings{BeyerLewerentzSimon, author = {Beyer, Dirk and Lewerentz, Claus and Simon, Frank}, title = {Impact of Inheritance on Metrics for Size, Coupling, and Cohesion in Object Oriented Systems}, series = {New approaches in software measurement, 10th international workshop, proceedings, IWSM 2000, Berlin, Germany, October 4 - 6, 2000}, booktitle = {New approaches in software measurement, 10th international workshop, proceedings, IWSM 2000, Berlin, Germany, October 4 - 6, 2000}, editor = {Abran, Alain and Dumke, Reiner}, publisher = {Springer}, address = {Berlin [u.a.]}, isbn = {3-540-41727-3}, pages = {1 -- 17}, language = {en} } @phdthesis{Simon, author = {Simon, Frank}, title = {Meßwertbasierte Qualit{\"a}tssicherung : ein generisches Distanzmaß zur Erweiterung bisheriger Softwareproduktmaße}, publisher = {Brandenburgische Techn.

Nowadays many companies develop their own dashboards for project control or use off-the-shelf tools that provide a predefined functionality. It is not clear how to tailor an existing tool to the specific needs and goals. An engineering-like approach providing the methodological foundation is needed for systematically defining and applying project control mechanisms. "Soft-Pit" is a research project focusing on an improvement-oriented approach for setting up and applying project control mechanisms in a goal-oriented way and evaluating the practical benefits of such a control center. This article describes the results of industrial case studies conducted in the context of the project. Moreover, lessons learned are discussed, related work is described, and future work is presented.}, language = {en} } @misc{MuellerTorgerAllertzetal., author = {M{\"u}ller, Felix and Torger, Bernhard and Allertz, Peter J. and J{\"a}hnichen, Klaus and Keßler, Stefan and M{\"u}ller, Martin and Simon, Frank and Salchert, Katrin and M{\"a}urer, Haike and Pospiech, Doris}, title = {Multifunctional crosslinkable itaconic acid copolymers for enzyme immobilization}, series = {European Polymer Journal}, volume = {102}, journal = {European Polymer Journal}, doi = {10.1016/j.eurpolymj.2018.03.014}, pages = {47 -- 55}, abstract = {UV-Crosslinkable itaconic copolymers are developed to provide new multifunctional materials for coatings which combine crosslinkable functionalities and the possibility to immobilize enzymes. The polymer-immobilized enzymes were used for water treatment to decompose persistent organic molecules. Introduction of suitable comonomers allows tailoring the mechanical and chemical properties for special applications. Copolymers containing MMA and itaconic anhydride were chosen because of the formation of long-term stable anhydride functionalities. These anhydride functionalities are employed to attach enzymes covalently. 4-Benzoylphenyl methacrylate is used as comonomer for UV-initiated crosslinking. Terpolymers are successfully obtained by radical copolymerization in solution. The copolymers are compared to poly(ethylene-alt-maleic anhydride) [P(EMA)] often used with respect to enzyme immobilization, activity and hydrolytic stability. The hydrolysis stability of the copolymers against water is studied by ATR-FTIR spectroscopy. Thin films are prepared on glass substrates in a layer-by-layer procedure by spin-coating. The layer formation is monitored by ATR-FTIR spectroscopy. UV-crosslinking of the copolymer films is performed taking the optimal irradiation dose that avoids polymer degradation. ATR-FTIR spectroscopy verifies the coupling reaction between amino groups of the enzyme and the anhydride groups on the surface of the crosslinked polymer film. The syringaldazine (4-hydroxy-3,5-dimethoxybenzaldehyde azine) test and 2,2´-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) assay demonstrate that the immobilized enzymes maintain their activities. The functional copolymers showed a significant effect in reduction of persistent organic pollutants in contaminated waste water.}, language = {de} }
