text: In order to increase mechanical strength, heat dissipation and ampacity and
to decrease failure through fatigue fracture, wedge copper wire bonding is being
introduced as a standard interconnection method for mass production. To achieve
the same process stability when using copper wire instead of aluminum wire a profound
understanding of the bonding process is needed. Due to the higher hardness of
copper compared to aluminum wire it is more difficult to approach the surfaces
of wire and substrate to a level where van der Waals forces are able to arise
between atoms. Also, enough friction energy referred to the total contact area
has to be generated to activate the surfaces. Therefore, a friction model is used
to simulate the joining process. This model calculates the resulting energy of
partial areas in the contact surface and provides information about the adhesion
process of each area. The focus here is on the arising of micro joints in the
contact area depending on the location in the contact and time. To validate the
model, different touchdown forces are used to vary the initial contact areas of
wire and substrate. Additionally, a piezoelectric tri-axial force sensor is built
up to identify the known phases of pre-deforming, cleaning, adhering and diffusing
for the real bonding process to map with the model. Test substrates as DBC and
copper plate are used to show the different formations of a wedge bond connection
due to hardness and reaction propensity. The experiments were done by using 500
$\mu$m copper wire and a standard V-groove tool.

text: Cavitation monitoring is desired to optimize the sonication for diverse sonochemical
processes and to detect changes or malfunctions during operation. In situ cavitation
measurements can be carried out by detection of the acoustic emissions of cavitation
bubbles by sensors in the liquid. However, in harsh environments sensors might
not be applicable. Thus, the impact of cavitation on the electrical signals of
a piezoelectric transducer has been analyzed as alternative method to measure
the threshold, strength and type of cavitation. The applicability has been tested
in three different setups to evaluate the general- izability of extracted indicators.
In all setups indicators for the cavitation thresholds could be derived from the
current signal. In two setups features showed two thresholds that may be linked
to the types of cavitation. However, only one feature derived from the current
signal in one particular setup correlated to the strength of cavitation. Cavitation
detection based on the current signal of the transducer is a useful method to
detect cavitation in harsh environments and without perturbing the sound field.
Once appli- cable indicators have been identified, they may easily be tracked
during the process. However, for more detailed studies about the cavitation activity
and its spatial distribution, measurements with in situ sensors are recommended.

text: Nowadays wire bonding is a widely-used technology for interconnecting chips
in the packaging industry. Thereby, it is known that the bond quality massively
depends upon the microstructure prevailing in the bond and consequently the materials
used as well as the bonding parameters. However the actually used materials such
as aluminum and gold are either characterized by comparibly poor conductivity
or high costs, respectively. Due to its outstanding properties copper is a more
attractive candidate. Still, a thorough investigation on the interrelationship
between the material combinations, the processing parameters and the resulting
microstructure for copper and aluminum wire bonding was not carried out yet. Depending
on the aforementioned factors the microstructural evolution can be completely
different during the bonding process. Therefore, this study focuses on the microstructural
evolution of heavy copper and heavy aluminum wires bonded on copper substrates.
The evolution of the wire microstructure as well as the wire-substrate-interface
was investigated by scanning electron microscope in combination with electron
backscatter diffraction and microhardness measurements. Various samples were extracted
at different points of the bonding process, namely the as-received condition,
after touchdown and after completed bonding. The results of the aluminum and copper
wires were compared to each other in both longitudinal and transversal direction.
It was found, that the two wire materials were completely different in the as-received
condition regarding the grain size, the grain morphology, the texture and the
microhardness. After touchdown the microstructure did not show significant changes
in both materials, yet a strain-hardening was observed in the copper wire resulting
from the touchdown force. When the bonding process was completed a different microstructure
could be observed in both the wire as well as the layer for the materials investigated.
Furthermore, a destinctive increase in the wire hardness could be found in case
of copper, which was not observed for the aluminum wire. The ramifications between
the two wire materials presented in this work will be discussed with the objective
of optimizing the quality of the bonds.

text: 'Wire bonding is the most common technology for connecting electronic components.
Due to their efficiency bond interconnections made of copper wire are used for
example in the aerospace and medical technology as well as in the fields of renewable
energies. One of the main cost factors in the manufacturing process is the consumables
like bonding tools. The technological transition to copper as wire material causes
significant wear on the millimeter large effective contact area of the bonding
tool. This wear leads to a loss by a factor of 30 of the number of reliable interconnections
which can be produced by a single tool. To reduce setting-up time in the production
and minimizing costs, an enlarged bonding tool lifetime is desirable. Consequently
a better understanding of wear and recognition of wear pattern is required. Therefore,
the paper presents an analyzing method of the tool topography change of a heavy
wire bonding tool by using a confocal microscope. Furthermore, the paper discusses
the identification of the main wear indicators by the help of the named topography
change for different bond parameters, like ultrasonic power and tool geometry.
Reference topography has been carried out by choosing typical parameters of the
production line. To judge whether the quality requirement of the bond connections
made by a single tool cannot be fulfilled shear test of the source bond have been
carried out after a defined number of produced bond connections. Main steps of
analysis: (I)Topography of the tool surface is sampled after a defined number
of bonds by means of a confocal microscope to detect the wear progress.(II)The
recorded data is filtered using Matlab. So, measurement errors can be eliminated
and the topography can be overlaid more easy to identify differences between diverse
tools or differences in wear stages of the same tool.(III)The subsequent discretization
of the topography into sub volumes allows to (IV)describe the loss of volume depending
on the position in the groove. Thereby, intermediate status of wear of one tool
can be used to obtain a persistent description of the topography change over the
number of produced bonds by interpolating the confocal data. Afterwards the persistent
change of the groove flank has been analyzed for the named test series to identify
the main wear indicators and their effect on shear forces. All worn tools show
dominant areas for volume loss especially for plastic deformation and accordingly
abrasion. These wear mechanism can be referred to the change of main parts of
the groove geometry like the rounding of the front and back radius. The most volume
loss was identified in the upper part of the tool flanks or rather at the transition
from the groove flank to the front or back radius. Furthermore the observation
of the center of the groove flank shows just a little change in volume. All in
all, the identification of the wear indicators will be discussed with the objective
of increasing the tool lifetime by optimizing the tool geometry without losses
in bond quality and reliability.'

text: Intelligent technical systems, which combine mechanical, electrical and software
engineering with methods from control engineering and advanced mathematics, go
far beyond the state of the art in mechatronics and open up fascinating perspectives.
Among these systems are so-called self-optimizing systems, which are able to adapt
their behavior autonomously and flexibly to changing operating conditions. The
Collaborative Research Center 614 "Self-optimizing concepts and structures in
mechanical engineering" pursued the long-term aim to enable others to develop
dependable self-optimizing systems. Assuring their dependability poses new challenges.
However, self-optimization also offers the possibility to adapt the system's behavior
to improve dependability during operation. The aim of this book is to provide
methods and techniques to master the challenges and to exploit the possibilities
given by self-optimization. The reader will be able to develop self-optimizing
systems that fulfill and surpass today’s dependability requirements easily. This
book is directed to researchers and practitioners alike. It gives a brief introduction
to the holistic development approach for self-optimizing mechatronic systems and
the steps required to assure a dependable product design starting with the very
early conceptual design phase. A guideline to select suitable methods for each
step and the methods themselves are included. Each method is individually introduced,
many examples and full references are given.

text: Piezoelectric inertia motors use the inertia of a body to drive it by means
of a friction contact in a series of small steps. It has been shown previously
in theoretical investigations that higher velocities and smoother movements can
be obtained if these steps do not contain phases of stiction (''stick-slip`` operation),
but use sliding friction only (''slip-slip`` operation). One very promising driving
option for such motors is the superposition of multiple sinusoidal signals or
harmonics. In this contribution, the theoretical results are validated experimentally.
In this context, a quick and reliable identification process for parameters describing
the friction contact is proposed. Additionally, the force generation potential
of inertia motors is investigated theoretically and experimentally. The experimental
results confirm the theoretical result that for a given maximum frequency, a signal
with a high fundamental frequency and consisting of two superposed sine waves
leads to the highest velocity and the smoothest motion, while the maximum motor
force is obtained with signals containing more harmonics. These results are of
fundamental importance for the further development of high-velocity piezoelectric
inertia motors.

text: (K,Na)NbO3 ceramics have attracted much attention as lead-free piezoelectric
materials with high piezoelectric properties. High-quality (K,Na)NbO3 ceramics
can be sintered using KNbO3 and NaNbO3 powders synthesized by a hydrothermal method.
In this study, to enhance the quality factor of the ceramics, high-power ultrasonic

text: Application of prognostics and health management (PHM) in the field of Proton
Exchange Membrane (PEM) fuel cells is emerging as an important tool in increasing
the reliability and availability of these systems. Though a lot of work is currently
being conducted to develop PHM systems for fuel cells, various challenges have
been encountered including the self-healing effect after characterization as well
as accelerated degradation due to dynamic loading, all which make RUL predictions
a difficult task. In this study, a prognostic approach based on adaptive particle
filter algorithm is proposed. The novelty of the proposed method lies in the introduction
of a self-healing factor after each characterization and the adaption of the degradation
model parameters to fit to the changing degradation trend. An ensemble of five
different state models based on weighted mean is then developed. The results show
that the method is effective in estimating the remaining useful life of PEM fuel
cells, with majority of the predictions falling within 5\% error. The method was
employed in the IEEE 2014 PHM Data Challenge and led to our team emerging the
winner of the RUL category of the challenge.

text: With the paradigm shift towards prognostic and health management (PHM) of
machinery, there is need for reliable PHM methodologies with narrow error bounds
to allow maintenance engineers take decisive maintenance actions based on the
prognostic results. Prognostics is mainly concerned with the estimation of the
remaining useful life (RUL) or time to failure (TTF). The accuracy of PHM methods
is usually a function of the features extracted from the raw data obtained from
sensors. In cases where the extracted features do not display clear degradation
trends, for instance highly loaded bearings, the accuracy of the state of the
art PHM methods is significantly affected. The data which lacks clear degradation
trend is referred to as non-trending data. This study presents a method for extracting
degradation trends from non-trending condition monitoring data for RUL estimation.
The raw signals are first filtered using a discrete wavelet transform (DWT) denoising
filter to remove noise from the acquired signals. Time domain, frequency domain
and time-frequency domain features are then extracted from the filtered signals.
An autoregressive model is then applied to the extracted features to identify
the degradation trends. Features representing the maximum health information are
then selected based on a performance evaluation criteria using extreme learning
machine (ELM) algorithm. The selected features can then be used as inputs in a
prognostic algorithm. The feasibility of the method is demonstrated using experimental
bearing vibration data. The performance of the method is evaluated on the accuracy
of RUL estimation and the results show that the method can be used to accurately
estimate RUL with a maximum error of 10\%.

text: The increasing demand for high reliability, safety and availability of technical
systems calls for innovative maintenance strategies. The use of prognostic health
management (PHM) approach where maintenance action is taken based on current and
future health state of a component or system is rapidly gaining popularity in
the maintenance industry. Multiclass support vector machines (MC-SVM) has been
identified as a promising algorithm in PHM applications due to its high classification
accuracy. However, it requires parameter tuning for each application, with the
objective of minimizing the classification error. This is a single objective optimization
problem which requires the use of optimization algorithms that are capable of
exhaustively searching for the global optimum parameters. This work proposes the
use of hybrid differential evolution (DE) and particle swarm optimization (PSO)
in optimally tuning the MC-SVM parameters. DE identifies the search limit of the
parameters while PSO finds the global optimum within the search limit. The feasibility
of the approach is verified using bearing run-to-failure data and the results
show that the proposed method significantly increases health state classification
accuracy.

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.

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.

text: Many nonlinear mechanical oscillators show excitation-dependent behavior.
In this paper, a new measurement approach is presented to analyze such structures.
The main advantage of the presented method is the high efficiency, since measurement
duration and loads to the structure are significantly reduced.

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.'

text: "The relevance of our definition for sensitivity in refractometric sensing,
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.

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.

text: We present a factor $14D^2$ approximation algorithm for the minimum linear
arrangement problem on series-parallel graphs, where $D$ is the maximum degree
in the graph. Given a suitable decomposition of the graph, our algorithm runs
in time $O(|E|)$ and is very easy to implement. Its divide-and-conquer approach
allows for an effective parallelization. Note that a suitable decomposition can
also be computed in time $O(|E|\log{|E|})$ (or even $O(\log{|E|}\log^*{|E|})$
on an EREW PRAM using $O(|E|)$ processors). For the proof of the approximation
ratio, we use a sophisticated charging method that uses techniques similar to
amortized analysis in advanced data structures. On general graphs, the minimum
linear arrangement problem is known to be NP-hard. To the best of our knowledge,
the minimum linear arrangement problem on series-parallel graphs has not been
studied before.

text: Ensuring memory access security is a challenge for reconfigurable systems
with multiple cores. Previous work introduced access monitors attached to the
memory subsystem to ensure that the cores adhere to pre-defined protocols when
accessing memory. In this paper, we combine access monitors with a formal runtime
verification technique known as proof-carrying hardware to guarantee memory security.
We extend previous work on proof-carrying hardware by covering sequential circuits
and demonstrate our approach with a prototype leveraging ReconOS/Zynq with an
embedded ZUMA virtual FPGA overlay. Experiments show the feasibility of the approach
and the capabilities of the prototype, which constitutes the first realization
of proof-carrying hardware on real FPGAs. The area overheads for the virtual FPGA
are measured as 2x-10x, depending on the resource type. The delay overhead is
substantial with almost 100x, but this is an extremely pessimistic estimate that
will be lowered once accurate timing analysis for FPGA overlays become available.
Finally, reconfiguration time for the virtual FPGA is about one order of magnitude
lower than for the native Zynq fabric.

text: Service matching approaches determine to what extent a provided service matches
a requester's requirements. This process is based on service specifications describing
functional (e.g., signatures) as well as non-functional properties (e.g., privacy
policies). However, we cannot expect service specifications to be complete as
providers do not want to share all details of their services' implementation.
Moreover, creating complete specifications requires much effort. In this paper,
we propose a novel service matching approach taking into account a service's signatures
and privacy policies. In particular, our approach applies fuzzy matching techniques
that are able to deal with incomplete service specifications. As a benefit, decision-making
based on matching results is improved and service matching becomes better applicable
in practice.

text: Various approaches in service engineering are based on servicemarkets where
brokers use service matching in order to performservice discovery. For matching,
a broker translates the specifications ofproviders' services and requesters' requirements
into her own specificationlanguage, in order to check their compliance using a
matcher. Thebroker's success depends on the configuration of her language and
itsmatcher because they in uence important properties like the effort forproviders
and requesters to create suitable specifications as well as accuracyand runtime
of matching. However, neither existing service specification languages, nor existing
matching approaches are optimized insuch way. Our approach automatically provides
brokers with an optimalconfiguration of a language and its matcher to improve
her success ina given market with respect to her strategy. The approach is based
onformalized configuration properties and a predefined set of configurationrules.
