The overlap percentages ranged from 40\% to 80\% in increments of 10\%. The new material properties of the fused metal were characterized using Weldware and their continuous cooling transformation curves. The convective and radiative heat transfer coefficients as well as the cooling time t8/5 were estimated using numerical formulations from relevant standards. The effects of the simulation geometry and mesh discretization were evaluated in terms of the factor F provided in Sysweld. Eventually, the parameters of Goldak's double ellipsoidal heat source model were determined for the welding simulation of overlapping beads on the plate and the simulated bead geometry, extent of the molten pool and the HAZ were compared with the macrographs of cross-sections of the experimental weldments. The results showed excellent matching, thus verifying this methodology for determination of welding heat source parameters.}, subject = {Angewandte Mathematik}, language = {en} } @article{KoenigKnecht, author = {K{\"o}nig, Reinhard and Knecht, Katja}, title = {Comparing two evolutionary algorithm based methods for layout generation: Dense packing versus subdivision}, series = {Artificial Intelligence for Engineering Design, Analysis and Manufacturing}, journal = {Artificial Intelligence for Engineering Design, Analysis and Manufacturing}, pages = {285 -- 299}, abstract = {We present and compare two evolutionary algorithm based methods for rectangular architectural layout generation: dense packing and subdivision algorithms.We analyze the characteristics of the two methods on the basis of three floor plan sce- narios.

In a following step, we discuss the methods with respect to their different user interaction capabilities. In addition, we show that each method has the capability to generate more complex L-shaped layouts. Finally,we conclude that neither of the methods is superior but that each of them is suitable for use in distinct application scenarios because of its different properties.}, subject = {Architektur}, language = {en} } @article{LuuMartinezRodrigoZabeletal., author = {Luu, M. and Martinez-Rodrigo, M.D. and Zabel, Volkmar and K{\"o}nke, Carsten}, title = {H∞ optimization of fluid viscous dampers for reducing vibrations of high-speed railway bridges}, series = {Journal of Sound and Vibration}, journal = {Journal of Sound and Vibration}, pages = {2421 -- 2442}, abstract = {H∞ optimization of fluid viscous dampers for reducing vibrations of high-speed railway bridges}, subject = {Angewandte Mathematik}, language = {en} }
