text: Different types of reduced graphene oxide and graphene oxide particles have
been studied regarding their influence on the curing behaviour of epoxy-amine
resins. Especially the specific surface area of reduced graphene oxide was selectively
influenced by controlled drying of the material. The different types of reduced
graphene oxide particles were used to produce epoxy-amine composites that significantly
change their curing behaviour and mechanical properties. A variety of surface
areas and compositions were prepared by combination of a fast heating rate and
different drying methods. The combination of freeze drying with a fast heating
rate leads to a large specific surface area of 680 m2/g. The morphologies of the
particles were observed by scanning electron microscope and the BET surface area
was measured with nitrogen-physisorption. The exfoliation quality was measured
by XRD. The generated graphene oxide and thermally reduced graphene oxide particles
were mixed with epoxy-amine resin. The curing behaviour was studied with rheological
and differential scanning calorimetry (DSC) measurements. We observed that different
surface functionalities lowers the Glass transition temperature and the gel time
of an epoxy-amine curing system. In addition, we found that generated graphene
oxide acts as flexibilizer. An increase of the deformation from 2.5 mm to 3.1 mm
was measured by Erichsen Cupping Test.

text: Die Vereinbarkeit einer erfolgreichen Bildungs- und Leistungssportkarriere
steht immer wieder zur Diskussion. Mit dem Ziel die Doppelbelastung aus Schule
und Sport abzupuffern und gleichzeitig eine positive Entwicklung der Sportler*innen
zu fördern, werden in NRW seit 2006 Sportschulen eingerichtet. Die Ergebnisse
einer Studie an einer solchen Realschule belegen, dass die sportlichen Heranwachsenden
hinsichtlich der Bildungskarriere im Untersuchungszeitraum nicht benachteiligt
sind.

text: 'In this paper we continue our study of bifurcations of solutions of boundary-value
problems for symplectic maps arising as Hamiltonian diffeomorphisms. These have
been shown to be connected to catastrophe theory via generating functions and
ordinary and reversal phase space symmetries have been considered. Here we present
a convenient, coordinate free framework to analyse separated Lagrangian boundary
value problems which include classical Dirichlet, Neumann and Robin boundary value
problems. The framework is then used to prove the existence of obstructions arising
from conformal symplectic symmetries on the bifurcation behaviour of solutions
to Hamiltonian boundary value problems. Under non-degeneracy conditions, a group
action by conformal symplectic symmetries has the effect that the flow map cannot
degenerate in a direction which is tangential to the action. This imposes restrictions
on which singularities can occur in boundary value problems. Our results generalise
classical results about conjugate loci on Riemannian manifolds to a large class
of Hamiltonian boundary value problems with, for example, scaling symmetries. '

text: The exploration of FPGAs as accelerators for scientific simulations has so
far mostly been focused on small kernels of methods working on regular data structures,
for example in the form of stencil computations for finite difference methods.
In computational sciences, often more advanced methods are employed that promise
better stability, convergence, locality and scaling. Unstructured meshes are shown
to be more effective and more accurate, compared to regular grids, in representing
computation domains of various shapes. Using unstructured meshes, the discontinuous
Galerkin method preserves the ability to perform explicit local update operations
for simulations in the time domain. In this work, we investigate FPGAs as target
platform for an implementation of the nodal discontinuous Galerkin method to find
time-domain solutions of Maxwell's equations in an unstructured mesh. When maximizing
data reuse and fitting constant coefficients into suitably partitioned on-chip
memory, high computational intensity allows us to implement and feed wide data
paths with hundreds of floating point operators. By decoupling off-chip memory
accesses from the computations, high memory bandwidth can be sustained, even for
the irregular access pattern required by parts of the application. Using the Intel/Altera
OpenCL SDK for FPGAs, we present different implementation variants for different
polynomial orders of the method. In different phases of the algorithm, either
computational or bandwidth limits of the Arria 10 platform are almost reached,
thus outperforming a highly multithreaded CPU implementation by around 2x.

text: "We present the submatrix method, a highly parallelizable method for the approximate
calculation of inverse p-th roots of large sparse symmetric matrices which are
required in different scientific applications. Following the idea of Approximate
Computing, we allow imprecision in the final result in order to utilize the sparsity
of the input matrix and to allow massively parallel execution. For an n x n matrix,
the proposed algorithm allows to distribute the calculations over n nodes with
only little communication overhead. The result matrix exhibits the same sparsity
pattern as the input matrix, allowing for efficient reuse of allocated data structures.\r\n\r\nWe
evaluate the algorithm with respect to the error that it introduces into calculated
results, as well as its performance and scalability. We demonstrate that the error
is relatively limited for well-conditioned matrices and that results are still
valuable for error-resilient applications like preconditioning even for ill-conditioned
matrices. We discuss the execution time and scaling of the algorithm on a theoretical
level and present a distributed implementation of the algorithm using MPI and
OpenMP. We demonstrate the scalability of this implementation by running it on
a high-performance compute cluster comprised of 1024 CPU cores, showing a speedup
of 665x compared to single-threaded execution."

text: Currently, it is state of the art to use precipitation hardening 6000-series
aluminum alloys to manufacture high-strength aluminum automotive parts by extrusion
or in a cold forming process. Alternatively, it is also possible to produce such
parts by the use of non-precipitation hardening 5000-series aluminum alloys in
a work-hardened condition. Therefore, BENTELER Automobiltechnik GmbH developed
a special sheet forming process, henceforth referred to as "flash forming process".
The application of the flash forming process, consisting of a rapid heat treatment
and a subsequent cold die stamping, increases the forming capability of the work-hardened
5000-series aluminum sheets and results in high-strength parts with a very good
ductility and weldability. In addition, this thermal assisted forming process
allows a cost-saving production of such high-strength aluminum parts due to lower
material costs of 5000-series aluminum alloys than those of a 6000-series material.
Furthermore, the weight-saving effects of "flash formed" parts can be higher compared
to extruded or cold formed 6000-series aluminum alloys. The suitability of the
process is evaluated by forming a commercial AW-5182 H18 aluminum sheet to a crash-relevant
automotive part. However, to accurately simulate the flash forming process itself,
a temperature dependent fracture model is necessary. Investigations on a coupon
basis also showed that the effect of adiabatic heating due to plastic work cannot
be neglected. In cooperation with Paderborn University, a detailed mechanical
testing, aided by digital image correlation (DIC) and thermal imaging, is carried
out to characterize the yield, hardening and fracture behavior at elevated temperatures.
The experimental tests are followed by the calibration of a FLD and an incremental
stress state dependent fracture model in LS-DYNA. Finally, the simulation models
are validated on a cross die deep drawn cup.
