text: "Today, organizations must deal with a plethora of IT security threats and
to ensure smooth and\r\nuninterrupted business operations, firms are challenged
to predict the volume of IT security vulnerabilities\r\nand allocate resources
for fixing them. This challenge requires decision makers to assess\r\nwhich system
or software packages are prone to vulnerabilities, how many post-release vulnerabilities\r\ncan
be expected to occur during a certain period of time, and what impact exploits
might have.\r\nSubstantial research has been dedicated to techniques that analyze
source code and detect security\r\nvulnerabilities. However, only limited research
has focused on forecasting security vulnerabilities\r\nthat are detected and reported
after the release of software. To address this shortcoming, we apply\r\nestablished
methodologies which are capable of forecasting events exhibiting specific time
series\r\ncharacteristics of security vulnerabilities, i.e., rareness of occurrence,
volatility, non-stationarity,\r\nand seasonality. Based on a dataset taken from
the National Vulnerability Database (NVD), we use\r\nthe Mean Absolute Error (MAE)
and Root Mean Square Error (RMSE) to measure the forecasting\r\naccuracy of single,
double, and triple exponential smoothing methodologies, Croston's methodology,\r\nARIMA,
and a neural network-based approach. We analyze the impact of the applied forecasting\r\nmethodology
on the prediction accuracy with regard to its robustness along the dimensions
of the\r\nexamined system and software package \"operating systems\", \"browsers\"
and \"office solutions\" and\r\nthe applied metrics. To the best of our knowledge,
this study is the first to analyze the effect\r\nof forecasting methodologies
and to apply metrics that are suitable in this context. Our results\r\nshow that
the optimal forecasting methodology depends on the software or system package,
as some\r\nmethodologies perform poorly in the context of IT security vulnerabilities,
that absolute metrics\r\ncan cover the actual prediction error precisely, and
that the prediction accuracy is robust within the\r\ntwo applied forecasting-error
metrics."

- description: "In many areas of product manufacturing individual components are
usually joined together to form complex structures with numerous joints. Mechanical
joining technology offers the possibility of joining structures with a wide
range of material-geometry combinations. In order to realize the increasing
number of varying products using different materials and designs within a process
chain, they need to be versatile.\r\n\r\nDue to changing properties of the materials
to be joined, tool geometries and process variables in mechanical joining processes,
especially clinching, must be continuously adapted which results in a limited
versatility of the process. In this regard, it is necessary to examine the robustness
of the clinching process in versatile process chains. Therefore, a method is
developed which describes the joint characteristics based on the material properties
in order to enable the investigation of the clinching process regarding the
robustness concerning continuously changing process and material conditions.\r\n\r\nThe
predictive accuracy of numerical simulations for mechanical joining processes
depends on the implemented material model, especially the plasticity of the
joining parts. Therefore, experimental material characterization processes are
used to determine material properties. Furthermore, clinched joints in different
material combinations are experimentally generated and examined. Based on these
investigations a simulation model of the joining process is developed as 2D-Clinching
FEM model in LS-Dyna. The Validation of the developed simulation model is ensured
by comparing the geometric formation of the joint and force-displacement curves
of the joining process with experimental generated joints. By combining the
simulation model with an optimization tool (LS-OPT) the influence of different
parameters on the joint characteristics is determined and the robustness of
the joining process in versatile process chains is investigated."

text: At Paderborn University, a new 6th semester geometry-course for upper secondary
student teachers has been designed and taught by the first author of this paper.
To show links between academic mathematics and school mathematics we established
so-called interface weeks. These are weeks during a course in which lecture, exercises
and homework focus on topics that are related to the normal canon of content but
specially chosen for their relevance in school contexts. In this article, we want
to present our design for an interface week on the topic of congruence. In order
to do so, we first illustrate how so-called interface aspects are used to systematize
the mathematical background of the topic, thus giving future mathematics teachers
the chance to act professionally. We then show examples of learning activities
and first results of the accompanying research.

text: This paper presents the results of an interlaboratory study of the rheological
properties of cement paste and ultrasound gel as reference substance. The goal
was to quantify the comparability and reproducibility of measurements of the Bingham
parameters yield stress and plastic viscosity when measured on one specific paste
composition and one particular ultrasound gel in different laboratories using
different rheometers and measurement geometries. The procedures for both in preparing
the cement paste and carrying out the rheological measurements on cement paste
and ultrasound gel were carefully defined for all of the study’s participants.
Different conversion schemes for comparing the results obtained with the different
measurement setups are presented here and critically discussed. The procedure
proposed in this paper ensured a reasonable comparability of the results with
a coefficient of variation for the yield stress of 27% and for the plastic viscosity
of 24%, despite the individual measurement series’ having been performed in different
labs with different rheometers and measurement geometries.

text: Since suspensions (e.g., in food, cement, or cosmetics industries)
tend to show wall slip, the application of structured measuring surfaces in rheometers
is widespread. Usually, for parallel-plate geometries, the tip-to-tip distance
is used for calculation of absolute rheological values, which implies that there
is no flow behind this distance. However, several studies show that this is not
true. Therefore, the measuring gap needs to be corrected by adding the effective
gap extension δ to the prescribed gap height H in order to obtain
absolute rheological properties. In this paper, we determine the effective gap
extension δ for different structures and fluids (Newtonian, shear thinning,
and model suspensions that can be adjusted to the behavior of real fluids) and
compare the corrected values to reference data. We observe that for Newtonian
fluids a gap- and material-independent correction function can be derived for
every measuring system, which is also applicable to suspensions, but not to shear
thinning fluids. Since this relation appears to be mainly dependent on the characteristics
of flow behaviour, we show that the calibration of structured measuring systems
is possible with Newtonian fluids and then can be transferred to suspensions up
to a certain particle content.
