text: An automotive suspension system represents one of the most complex and important
systems in a passenger vehicle, which has to ensure a robust and optimized contact
between the wheels and the road at any time. For improving a suspension system
it is important to take an investigative look at the interaction between suspension,
tire and road dynamics. Thus a part of a study into aspects of suspension modeling
on multi-body simulations of rear multi-link suspension system dynamics with focus
on the tire footprint area is presented in this work.

text: So-called reliability adaptive systems are able to adapt their system behavior
based on the current reliability of the system. This allows them to react to changed
operating conditions or faults within the system that change the degradation behavior.
To implement such reliability adaptation, self-optimization can be used. A self-optimizing
system pursues objectives, of which the priorities can be changed at runtime,
in turn changing the system behavior. When including system reliability as an
objective of the system, it becomes possible to change the system based on the
current reliability as well. This capability can be used to control the reliability
of the system throughout its operation period in order to achieve a pre-defined
or user-selectable system lifetime. This way, optimal planning of maintenance
intervals is possible while also using the system capabilities to their full extent.
Our proposed control system makes it possible to react to changed degradation
behavior by selecting objectives of the self-optimizing system and in turn changing
the operating parameters in a closed loop. A two-stage controller is designed
which is used to select the currently required priorities of the objectives in
order to fulfill the desired usable lifetime. Investigations using a model of
an automotive clutch system serve to demonstrate the feasibility of our controller.
It is shown that the desired lifetime can be achieved reliably.

text: Intelligent mechatronic systems, such as self-optimizing systems, allow an
adaptation of the system behavior at runtime based on the current situation. To
do so, they generally select among several pre-defined working points. A common
method to determine working points for a mechatronic system is to use model-based
multiobjective optimization. It allows finding compromises among conflicting objectives,
called objective functions, by adapting parameters. To evaluate the system behavior
for different parameter sets, a model of the system behavior is included in the
objective functions and is evaluated during each function call. Intelligent mechatronic
systems also have the ability to adapt their behavior based on their current reliability,
thus increasing their availability, or on changed safety requirements; all of
which are summed up by the common term dependability. To allow this adaptation,
dependability can be considered in multiobjective optimization by including dependability-related
objective functions. However, whereas performance-related objective functions
are easily found, formulation of dependability-related objective functions is
highly system-specific and not intuitive, making it complex and error-prone. Since
each mechatronic system is different, individual failure modes have to be taken
into account, which need to be found using common methods such as Failure-Modes
and Effects Analysis or Fault Tree Analysis. Using component degradation models,
which again are specific to the system at hand, the main loading factors can be
determined. By including these in the model of the system behavior, the relation
between working point and dependability can be formulated as an objective function.
In our work, this approach is presented in more detail. It is exemplified using
an actively actuated single plate dry clutch system. Results show that this approach
is suitable for formulating dependability-related objective functions and that
these can be used to extend system lifetime by adapting system behavior.

text: A model to calculate the locally resolved tangential contact forces of the
wheel rail contact with respect to contact kinematics, material and surface properties
as well as temperature is introduced. The elasticity of wheel and rail is modeled
as an elastic layer consisting of point contact elements connected by springs
to each other and to the wheel. Each element has two degrees of freedom in tangential
directions. The resulting total stiffness matrix is reduced to calculate only
the position of the elements in contact. Friction forces as well as contact stiffnesses
are incorporated by a nonlinear force-displacement characteristic, which originates
from a detailed contact model. The contact elements are transported through the
contact zone in discrete time steps. After each time step an equilibrium is calculated.
For all elements, their temperature and its influence on local friction are regarded
by calculating friction power and temperature each time step.

text: This paper discusses the refinement of multibody models by integration of
flexible bodies and by considering nonlinearities from contacts. It presents common
approaches for contact modeling in multibody simulations and strategies to include
flexible bodies. A contact model is implemented in the elastic multibody model.
Experimental results show that significant effects of system dynamics can be modeled
by use of a multibody model including elastic bodies and contacts.

measurement technique with a prediction method for peak bending behavior. This
combination allows the analysis of the dynamic behavior of mechanical structures
at distinctly reduced measurement durations and has the advantage of reducing
high excitation impacts on the structure under test.

text: A measurement method is presented that combines the advantages of the multisine
measurement technique with a prediction method for peak bending behavior. This
combination allows the analysis of the dynamic behavior of mechanical structures
at distinctly reduced measurement durations and has the advantage of reducing
high excitation impacts on the structure under test. After a brief presentation
of the algorithm, the validity scope of the approach is investigated with emphasis
on an exemplary error investigation.

text: Power semiconductor modules are used to control and switch high electrical
currents and voltages. Within the power module package wire bonding is used as
an interconnection technology. In recent years, aluminum wire has been used preferably,
but an ever-growing market of powerful and efficient power modules requires a
material with better mechanical and electrical properties. For this reason, a
technology change from aluminum to copper is indispensable. However, the copper
wire bonding process reacts more sensitive to parameter changes. This makes manufacturing
reliable copper bond connections a challenging task. The aim of the BMBF funded
project Itsowl-InCuB is the development of self-optimizing techniques to enable
the reliable production of copper bond connections under varying conditions. A
model of the process is essential to achieve this aim. This model needs to include
the dynamic elasto-plastic deformation, the ultrasonic softening effect and the
proceeding adhesion between wire and substrate. This paper focusses on the pre-deformation
process. In the touchdown phase, the wire is pressed into the V-groove of the
tool and a small initial contact area between wire and substrate arise. The local
characteristics of the material change abruptly because of the cold forming. Consequently,
the pre-deformation has a strong effect on the joining process. In [1], a pre-cleaning
effect during the touchdown process of aluminum wires by cracking of oxide layers
was presented. These interactions of the process parameters are still largely
unknown for copper. In a first step, this paper validates the importance of modeling
the pre-deformation by showing its impact on the wire deformation characteristic
experimentally. Creating cross-section views of pre-deformed copper wires has
shown a low deformation degree compared to aluminum. By using a digital microscope
and a scanning confocal microscope an analysis about the contact areas and penetration
depths after touchdown has been made. Additionally, it has to be taken into account
that the dynamical touchdown force depends on the touchdown speed and the touchdown
force set in the bonding machine. In order to measure the overshoot in the force
signals, a strain gauge sensor has been used. Subsequently, the affecting factors
have been interpreted independently Furthermore, the material properties of copper
wire have been investigated with tensile tests and hardness measurements. In a
second step, the paper presents finite element models of the touchdown process
for source and destination bonds. These models take the measured overshoot in
the touchdown forces into account. A multi-linear, isotropic material model has
been selected to map the material properties of the copper. A validation of the
model with the experimental determined contact areas, normal pressures and penetration
depths reveals the high model quality. Thus, the simulation is able to calculate
and visualize the three dimensional pre-deformation with an integrated material
parameter of the wire if the touchdown parameters of the bonding machine are known.
Based on the calculated deformation degrees of wire and substrate, it is probably
possible to investigate the effect of the pre-deformation on the pre-cleaning
phase in the copper wire bonding.

text: In power electronics, ultrasonic wire bonding is used to connect the electrical
terminals of power modules. To implement a self-optimization technique for ultrasonic
wire bonding machines, a model of the process is essential. This model needs to
include the so called ultrasonic softening effect. It is a key effect within the
wire bonding process primarily enabling the robust interconnection between the
wire and a substrate. However, the physical modeling of the ultrasonic softening
effect is notoriously difficult because of its highly non-linear character and
the absence of a proper measurement method. In a first step, this paper validates
the importance of modeling the ultrasonic softening by showing its impact on the
wire deformation characteristic experimentally. In a second step, the paper presents
a data-driven model of the ultrasonic softening effect which is constructed from
data using machine learning techniques. A typical caveat of data-driven modeling
is the need for training data that cover the considered domain of process parameters
in order to achieve accurate generalization of the trained model to new process
configurations. In practice, however, the space of process parameters can only
be sampled sparsely. In this paper, a novel technique is applied which enables
the integration of prior knowledge about the process into the datadriven modeling
process. It turns out that this approach results in accurate generalization of
the data-driven model to unseen process parameters from sparse data.

text: 'A fundamental problem for peer-to-peer systems is to maintain connectivity
while nodes are leaving, i.e., the nodes requesting to leave the peer-to-peer
system are excluded from the overlay network without affecting its connectivity.
There are a number of studies for safe node exclusion if the overlay is in a well-defined
state initially. Surprisingly, the problem is not formally studied yet for the
case in which the overlay network is in an arbitrary initial state, i.e., when
looking for a self-stabilizing solution for excluding leaving nodes. We study
this problem in two variants: the Finite Departure Problem (FDP) ) and the Finite
Sleep Problem (FSP). In the FDP the leaving nodes have to irrevocably decide when
it is safe to leave the network, whereas in the FSP, this leaving decision does
not have to be final: the nodes may resume computation if necessary. We show that
there is no self-stabilizing distributed algorithm for the FDP, even in a synchronous
message passing model. To allow a solution, we introduce an oracle called NIDEC
and show that it is sufficient even for the asynchronous message passing model
by proposing an algorithm that can solve the FDP using NIDEC. We also show that
a solution to the FSP does not require an oracle.'

being the relative change in the transmittance\r\nof a certain output channel
of an optical device over the change in the refractive index of the probed\r\nmaterial,
is discussed. It is compared to one based on spectral shift per refractive index
unit change. Further, there\r\nis discussion on how group delay and sensitivity
are interrelated and can be converted into each other and which\r\nphysical quantities
are relevant for high sensitivity. As a by-product of the theory presented, a

text: Service Oriented Architectures (SOAs) enable the reuse and substitution of
software services to develop highly flexible software systems. To benefit from
the growing plethora of available services, sophisticated service discovery approaches
are needed that bring service requests and offers together. Such approaches rely
on rich service descriptions, which specify also the behavior of provided/requested
services, e.g., by pre- and postconditions of operations. As a base for the specification
a data schema is used, which specifies the used data types and their relations.
However, data schemas are typically heterogeneous wrt. their structure and terminology,
since they are created individually in their diverse application contexts. As
a consequence the behavioral models that are typed over the heterogeneous data
schemas, cannot be compared directly. In this paper, we present an holistic approach
to normalize rich service description models to enable behavior-aware service
discovery. The approach consists of a matching algorithm that helps to resolve
structural and terminological heterogeneity in data schemas by exploiting domain-specific
background ontologies. The resulting data schema mappings are represented in terms
of Query View Transformation (QVT) relations that even reflect complex n:m correspondences.
By executing the transformation, behavioral models are automatically normalized,
which is a prerequisite for a behavior-aware operation matching.

text: We consider a multilevel network game, where nodes can improvetheir communication
costs by connecting to a high-speed network.The n nodes are connected by a static
network and each node can decideindividually to become a gateway to the high-speed
network. The goalof a node v is to minimize its private costs, i.e., the sum (SUM-game)
ormaximum (MAX-game) of communication distances from v to all othernodes plus
a fixed price α > 0 if it decides to be a gateway. Between gatewaysthe communication
distance is 0, and gateways also improve othernodes’ distances by behaving as
shortcuts. For the SUM-game, we showthat for α ≤ n − 1, the price of anarchy is
Θ (n/√α) and in this rangeequilibria always exist. In range α ∈ (n−1, n(n−1))
the price of anarchyis Θ(√α), and for α ≥ n(n − 1) it is constant. For the MAX-game,
weshow that the price of anarchy is either Θ (1 + n/√α), for α ≥ 1, orelse 1.
Given a graph with girth of at least 4α, equilibria always exist.Concerning the
dynamics, both games are not potential games. For theSUM-game, we even show that
it is not weakly acyclic.
