Firstly, the characterization of the intestine tissues is discussed for a nearly incompressible hyperelastic fiber-reinforced Holzapfel-Gasser-Ogden constitutive model in virgin passive loading conditions. The stability of the evaluated material parameters is checked for the polyconvexity of the adopted strain energy function using positive eigenvalue constraints of the Hessian matrix with MATLAB. The constitutive material description of the intestine with two collagen fibers in the submucosal and muscular layer each has been implemented in the FORTRAN platform of the commercial finite element software LS-DYNA, and two equibiaxial tensile simulations are presented to validate the results with the optical strain images obtained from the experiments. Furthermore, this paper also reviews the existing models of the active smooth muscle cells, but these models have not been computationally studied here. The review part shows that the constitutive models originally developed for the active contraction of skeletal muscle based on Hill's three-element model, Murphy's four-state cross-bridge chemical kinetic model and Huxley's sliding-filament hypothesis, which are mainly used for arteries, are appropriate for numerical contraction numerical analysis of the large intestine.}, language = {en} } @article{Wollert2002, author = {Wollert, J{\"o}rg}, title = {Vierzig Jahre Software-Desaster : zehn Regeln als R{\"u}stzeug, um die Herausforderung Software-Entwicklung zu meistern}, series = {Elektronik : Fachmedium f{\"u}r industrielle Anwender und Entwickler}, volume = {Bd. 51}, journal = {Elektronik : Fachmedium f{\"u}r industrielle Anwender und Entwickler}, number = {H. 25}, issn = {0013-5658}, pages = {110 -- 115}, year = {2002}, language = {de} } @article{KlockeRichertSube2018, author = {Klocke, Martina and Richert, Vera and Sube, Maike}, title = {Vier Jahre „Guter Studienstart im Ingenieurbereich": Entwicklung und Perspektiven des „Nullten Semesters" in Aachen}, series = {Zeitschrift f{\"u}r Beratung und Studium}, volume = {13}, journal = {Zeitschrift f{\"u}r Beratung und Studium}, number = {1}, publisher = {Universit{\"a}tsverlag Webler}, address = {Bielefeld}, issn = {1860-3068}, pages = {17 -- 22}, year = {2018}, abstract = {Bereits 2015 wurde in der Zeitschrift „Qualit{\"a}t in der Wissenschaft" (QiW) {\"u}ber das Kooperationsprojekt „Guter Studienstart im Ingenieurbereich", das Orientierungssemester von RWTH und FH Aachen, berichtet.
