A priori fully populated covariance matrices in least squares adjustment case study: GPS relative positioning verfasst von Gaël Kermarrec, Steffen Schön Abstract In this contribution, using the example of the M tern covariance matrices, we study systematically the effect of apriori fully populated variance covariance matrices VCM in the Gauss Markov model, by varying both the smoothness and the correlation length of the covariance fun...

Testing dose response relationships with a priori unknown, possibly nonmonotone shapes authored by F. Bretz, L. A. Hothorn Abstract Usually, a monotone dose response dependence can be assumed for the simultaneous comparison of increasing levels of a certain drug.

Anticipatory Online Compensation of Tool Deflection Using a Priori Information from Process Planning verfasst von Berend Denkena, Benjamin Bergmann, Tim Schumacher Abstract Removing excess material from build up welding by milling is a critical step in the repair of blades from aircraft engines.

An exact Cochran Armitage test for trend when dose response shapes are a priori unknown authored by Markus Neuhäuser, Ludwig A. Hothorn Abstract The Cochran Armitage test is a widely used test for trend among binomial proportions of a dose response relationship.

Robust surface fitting Using weights based on à priori knowledge about the measurement process authored by Nils Langholz, Jörg Seewig, Eduard Reithmeier Abstract Modern surface layouts like automotive cylinder liners, turbine blades or seal faces need high information content.

A GPU based ray tracing approach for the prediction of multireflections on measurement objects and the a priori estimation of low reflection measurement poses authored by Philipp Middendorf, Pascal Kern, Nils Frederik Melchert, Markus Kästner, Eduard Reithmeier Abstract For the automated optical inspection of manufactured components with complex geometries or highly reflective surfaces, a suitable selection of measurement poses and th...

Training agents for unknown logistics problems verfasst von Elisa Schmid, Matthias Becker Abstract A methodology on how to prepare agents to succeed on a priori unknown logistics problems is presented. The training of the agents is and can only be executed using a small number of test problems that are taken out of a broad class of generalized logistics problems.

As a model problem, also a variational inequality for the single layer operator is considered. A priori estimates are obtained for Galerkin approximations both to the variational inequality and the mixed formulation in the case of a flat contact area, where the existence of solutions to the continuous problem is known.

Extreme ultraviolet fourier transform spectroscopy with high order harmonics authored by M. Kova ev, S. V. Fomichev, E. Priori, Y. Mairesse, H. Merdji, P. Monchicourt, P. Breger, J. Norin, A. Persson, A. L Huillier, C. G. Wahlström, B. Carr , P. Sali res Abstract We demonstrate a new scheme for extreme ultraviolet xuv Fourier transform spectroscopy based on the generation of two phase locked high harmonic beams.

Manipulating intense XUV coherent light in the temporal domain verfasst von H. Merdji, J. F. Hergott, M. Kovacev, E. Priori, P. Salières, B. Carr Abstract In this article, we demonstrate the generation of four phase locked harmonic pulses separated in time using frequency domain interferometry.

Scherf Abstract Due to the fact that in contact problems the contact area is not known a priori, a sufficient discretization to obtain a convergent finite element solution cannot be supplied from the outset. Therefore it is necessary to use adaptive finite element methods to adjust automatically the mesh sizes not only in the bodies under consideration but also in the contact zone.
