This is achieved by discretizing the resulting system of boundary integral equations in combination with a nonlinear eigenvalue solver. Numerical results are given to show that this new approach can provide better results than the finite element method when dealing with general domains.}, language = {en} } @article{FerreinSchifferBooysenetal.2016, author = {Ferrein, Alexander and Schiffer, Stefan and Booysen, Tracy and Stopforth, Riaan}, title = {Why it is harder to run RoboCup in South Africa: Experiences from German South African collaborations}, series = {International Journal of Advanced Robotic Systems}, volume = {13}, journal = {International Journal of Advanced Robotic Systems}, number = {5}, issn = {1729-8806}, doi = {10.1177/1729881416662789}, pages = {1 -- 13}, year = {2016}, abstract = {Robots are widely used as a vehicle to spark interest in science and technology in learners. A number of initiatives focus on this issue, for instance, the Roberta Initiative, the FIRST Lego League, the World Robot Olympiad and RoboCup Junior. Robotic competitions are valuable not only for school learners but also for university students, as the RoboCup initiative shows. Besides technical skills, the students get some project exposure and experience what it means to finish their tasks on time. But qualifying students for future high-tech areas should not only be for students from developed countries. In this article, we present our experiences with research and education in robotics within the RoboCup initiative, in Germany and South Africa; we report on our experiences with trying to get the RoboCup initiative in South Africa going. RoboCup has a huge support base of academic institutions in Germany; this is not the case in South Africa. We present our 'north-south' collaboration initiatives in RoboCup between Germany and South Africa and discuss some of the reasons why we think it is harder to run RoboCup in South Africa.}, language = {en} } @article{BiselliSchmidtBuechsetal.1999, author = {Biselli, Manfred and Schmidt, Sebastian and B{\"u}chs, Jochen and Born, Christoph}, title = {A new correlation for the wall-to-fluid mass transfer in liquid-sol fluidized beds / Schmidt, S. ; B{\"u}chs, J. ; Born, C. ; Biselli, M.}, series = {Chemical Engineering Science. 54 (1999), H. 6}, journal = {Chemical Engineering Science. 54 (1999), H. 6}, isbn = {0009-2509}, pages = {829 -- 839}, year = {1999}, language = {en} } @article{BiselliBornThoemmesetal.1996, author = {Biselli, Manfred and Born, Christoph and Th{\"o}mmes, J. and Wandrey, C.}, title = {An approach to integrated antibody production: Coupling of fluidized bed cultivation and fluidized bed adsorption / Born, C. ; Th{\"o}mmes, J. ; Biselli, M. ; Wandrey, C. ; Kula, M.-R.}, series = {Bioprocess Engineering. 15 (1996), H. 1}, journal = {Bioprocess Engineering. 15 (1996), H. 1}, isbn = {1615-7591}, pages = {21 -- 29}, year = {1996}, language = {en} } @article{BiselliBornWandrey1995, author = {Biselli, Manfred and Born, Christoph and Wandrey, C.}, title = {Oxygen transfer from the gasphase to the immobilized cells in membrane aerated fluidized beds / Born, C. ; Biselli, M. ; Wandrey, C.}, series = {Animal cell technology : basic \& applied aspects : proceedings of the Eighth Annual Meeting of the Japanese Association for Animal Cell Technology, Iizuka, Fukuoka, Japan, November 6-10, 1995 / edited by K.

Sapphire chips, beads, and powder were first modified with (3-aminopropyl) triethoxysilane (APTES), followed by succinic anhydride (SA), and finally single-stranded probe DNA was EDC coupled to the functionalized layer. The presence of the APTES-SA layer on sapphire powders was confirmed by thermogravimetric analyis and Fourier-transform infrared spectroscopy. Using planar sapphire chips as substrates and X-ray photoelectron spectroscopy (XPS) as surface-sensitive tool, the sequence of individual layers was analyzed with respect to their chemical state, enabling the quantification of areal densities of the involved molecular units. Fluorescence microscopy was used to demonstrate the hybridization of fluorescently tagged target DNA to the probe DNA, including denaturation- and re-hybridization experiments. Due to its high thermal conductivity, synthetic sapphire is especially suitable as a chip material for the heat-transfer method, which was employed to distinguish complementary- and non-complementary DNA duplexes containing single-nucleotide polymorphisms. These results indicate that it is possible to detect mutations electronically with a chemically resilient and electrically insulating chip material.}, language = {en} }
