text: 'Efficiently parallelizable parameterized problems have been classified as
being either in the class FPP (fixed-parameter parallelizable) or the class PNC
(parameterized analog of NC), which contains FPP as a subclass. In this paper,
we propose a more restrictive class of parallelizable parameterized problems called
fixed-parameter parallel-tractable (FPPT). For a problem to be in FPPT, it should
possess an efficient parallel algorithm not only from a theoretical standpoint
but in practice as well. The primary distinction between FPPT and FPP is the parallel
processor utilization, which is bounded by a polynomial function in the case of
FPPT. We initiate the study of FPPT with the well-known k-vertex cover problem.
In particular, we present a parallel algorithm that outperforms the best known
parallel algorithm for this problem: using O(m) instead of O(n2) parallel processors,
the running time improves from 4logn+O(kk) to O(k⋅log3n), where m is the number
of edges, n is the number of vertices of the input graph, and k is an upper bound
of the size of the sought vertex cover. We also note that a few P-complete problems
fall into FPPT including the monotone circuit value problem (MCV) when the underlying
graphs are bounded by a constant Euler genus.'

text: We consider a scheduling problem where machines need to be rented from the
cloud in order to process jobs. There are two types of machines available which
can be rented for machine-type dependent prices and for arbitrary durations. However,
a machine-type dependent setup time is required before a machine is available
for processing. Jobs arrive online over time, have machine-type dependent sizes
and have individual deadlines. The objective is to rent machines and schedule
jobs so as to meet all deadlines while minimizing the rental cost. Since we observe
the slack of jobs to have a fundamental influence on the competitiveness, we study
the model when instances are parameterized by their (minimum) slack. An instance
is called to have a slack of $\beta$ if, for all jobs, the difference between
the job's release time and the latest point in time at which it needs to be started
is at least $\beta$. While for $\beta series = {LNCS}

text: We study a new class of games which generalizes congestion games and its bottleneck
variant. We introduce congestion games with mixed objectives to model network
scenarios in which players seek to optimize for latency and bandwidths alike.
We characterize the existence of pure Nash equilibria (PNE) and the convergence
of improvement dynamics. For games that do not possess PNE we give bounds on the
approximation ratio of approximate pure Nash equilibria.

text: Additive Manufacturing (AM), also known as 3D printing, is a relatively new
technology which enables the toolless production of components and entire assemblies
directly from a CAD file. Today, the technology is still not widely used in industrial
production. It is mainly limited to special applications, although it shows great
potential. In this paper, first approaches are shown to apply AM to the production
of rotors for permanent magnet synchronous machines (PMSM). The possibilities
of a lightweight design with a low moment of inertia as well as the influence
on the magnetic anisotropy for an improved sensorless control of PMSM are pointed
out. The results clearly demonstrate the great potential of additive manufacturing
in electrical engineering applications.

text: Additive Manufacturing offers a great potential for the optimization of products.
Therefore different approaches are feasible to exploit these potentials for elaborating
optimal solutions. For example these include optimization of weight or stiffness
of structural components as well as the integration of functions and other entities
of assemblies. Note, however, that additive manufacturing processes have process
specific limitations. Products, components and assemblies, as well as procedures
for the design and production preparation must be optimized with regard to a successful
additive manufacturing. The use of already known tools for the optimization and
design needs to be reconsidered and adapted to theadditive manufacturing. This
also includes the production planning with component orientation in build chamber
as well as a necessary quality management system. This paper shows several ways
for product optimization with additive manufacturing, often based on topology
optimization, and procedures for information gathering, decision making and shape
determination for part optimization for Additive Manufacturing.

text: Nowadays, the material efficiency and part reliability are two majorissues
in product development. Thus a product optimization often requires complex structures
that are hard to be manufactured conventionally. Additive Manufacturing (AM) however
offers great potentials for producing complex shaped parts economically. Different
approaches are feasible to exploit these potentials based on the part’s application
from shape optimization of structural components to the integration of functions
and other entities of assemblies. Several parameters are defined that influence
the costs and quality of the future product and carefully have to be balanced.
To do so, the use of already known tools for the optimization and design needs
to be reconsidered and adapted to the special characteristics of AM. As not all
optimization potentials can be realized perfectly, a decision methodology is required
to obtain the relevant potentials and to get to a trade-off between all requirements
including the ecological impact. The paper shows different approaches for product
optimization with AM and procedures for decision making in order to get to the
optimal solution.

text: "Traditional cellular networks are forced to remain active regardless of the
actual amount of traffic that is currently produced/requested, with a clear waste
of energy. Two-layer mobile networks with separated signalling and data layers
have been recently proposed for energy savings in future implementations. These
networks are able to switch off unneeded data cells completely while maintaining
full coverage with their signalling cells, thus saving energy. In this demonstration,
we showcase a testbed that uses Wi-Fi access points to emulate small cells of
the data layer and a publicly available cellular connection as the signalling
layer. We use off-the-shelf Android smartphones with an ad-hoc networking management
module and a MultiPath TCP-enabled kernel to manage the Wi-Fi and cellular interfaces
simultaneously.\r\nThe testbed is used to demonstrate the general feasibility
of this layered architecture and to facilitate experiments with network-wide resource
optimization. "

text: In a wide range of applications, it is desirable to optimally control a system
with respect to concurrent, potentially competing goals. This gives rise to a
multiobjective optimal control problem where, instead of computing a single optimal
solution, the set of optimal compromises, the so-called Pareto set, has to be
approximated. When it is not possible to compute the entire control trajectory
in advance, for instance due to uncertainties or unforeseeable events, model predictive
control methods can be applied to control the system during operation in real
time. In this article, we present an algorithm for the solution of multiobjective
model predictive control problems. In an offline scenario, it can be used to compute
the entire set of optimal compromises whereas in a real time scenario, one optimal
compromise is computed according to an operator's preference. The results are
illustrated using the example of an industrial laundry. A logistics model of the
laundry is developed and then utilized in the optimization routine. Results are
presented for an offline as well as an online scenario.

text: Tire-wheel assembly is the only connection between road and vehicle. Contacting
directly with road within postcard size of contact area, it is mounted and guided
by the suspension system. Therefore kinematics and compliances of suspension system
greatly influence the frictional coupling of tire tread elements and road surface
asperities by affecting pressure and sliding velocity distribution in the contact
zone. This study emphasizes the development of a numerical methodology for frictional
rolling contact analysis with focus on interaction of suspension system dynamics
and tire-road contact using ADAMS. For this purpose a comprehensive flexible multibody
system of the multi-link rear suspension is established, where both flexible and
rigid bodies are modeled to allow large displacements with included elastic effects.
To meet accuracy requirements for the high frequency applications, such as road
excitations, the amplitude- and frequency-dependency of rubber-metal bushings
is included. Furthermore the proposed flexible viscoelastic suspension model is
enhanced by a Flexible Ring Tire Model (FTire), which describes a 3D tire dynamic
response and covers any road excitations by tread submodel connected to road surface
model. Concerning the verification and validation procedure numerous experiments
are carried out to confirm the validity and the accuracy of both the developed
submodels and the entire model. The devised approach makes it possible to investigate
the influence of suspension system design on dynamical rolling contact and to
evaluate tire tread wear. Therefore it can be a useful tool to predict frictional
power distribution within the contact area under more realistic conditions.

text: Usage of copper wire bonds allows to push power boundaries imposed by aluminum
wire bonds. Copper allows higher electrical, thermal and mechanical loads than
aluminum, which currently is the most commonly used material in heavy wire bonding.
This is the main driving factor for increased usage of copper in high power applications
such as wind turbines, locomotives or electric vehicles. At the same time, usage
of copper also increases tool wear and reduces the range of parameter values for
a stable process, making the process more challenging. To overcome these drawbacks,
parameter adaptation at runtime using self-optimization is desired. A self-optimizing
system is based on system objectives that evaluate and quantify system performance.
System parameters can be changed at runtime such that pre-selected objective values
are reached. For adaptation of bond process parameters, model-based self-optimization
is employed. Since it is based on a model of the system, the bond process was
modeled. In addition to static model parameters such as wire and substrate material
properties and vibration characteristics of transducer and tool, variable model
inputs are process parameters. Main simulation result is bonded area in the wiresubstrate
contact. This model is then used to find valid and optimal working points before
operation. The working point is composed of normal force and ultrasonic voltage
trajectories, which are usually determined experimentally. Instead, multiobjective
optimalization is used to compute trajectories that simultaneously optimize bond
quality, process duration, tool wear and probability of tool-substrate contacts.
The values of these objectives are computed using the process model. At runtime,
selection among pre-determined optimal working points is sufficient to prioritize
individual objectives. This way, the computationally expensive process of numerically
solving a multiobjective optimal control problem and the demanding high speed
bonding process are separated. To evaluate to what extent the pre-defined goals
of self-optimization are met, an offthe- shelf heavy wire bonding machine was
modified to allow for parameter adaptation and for transmitting of measurement
data at runtime. This data is received by an external computer system and evaluated
to select a new working point. Then, new process parameters are sent to the modified
bonding machine for use for subsequent bonds. With these components, a full self-optimizing
system has been implemented.

text: To increase quality and reliability of copper wire bonds, self-optimization
is a promising technique. For the implementation of self-optimization for ultrasonic
heavy copper wire bonding machines, a model of stick-slip motion between tool
and wire and between wire and substrate during the bonding process is essential.
Investigations confirm that both of these contacts do indeed show stick-slip movement
in each period oscillation. In a first step, this paper shows the importance of
modeling the stick-slip effect by determining, monitoring and analyzing amplitudes
and phase angles of tooltip, wire and substrate experimentally during bonding
via laser measurements. In a second step, the paper presents a dynamic model which
has been parameterized using an iterative numerical parameter identification method.
This model includes Archard’s wear approach in order to compute the lost volume
of tool tip due to wear over the entire process time. A validation of the model
by comparing measured and calculated amplitudes of tool tip and wire reveals high
model quality. Then it is then possible to calculate the lifetime of the tool
for different process parameters, i.e. values of normal force and ultrasonic voltage.

text: We present a system for the 4th CHiME challenge which significantly increases
the performance for all three tracks with respect to the provided baseline system.
The front-end uses a bi-directional Long Short-Term Memory (BLSTM)-based neural
network to estimate signal statistics. These then steer a Generalized Eigenvalue
beamformer. The back-end consists of a 22 layer deep Wide Residual Network and
two extra BLSTM layers. Working on a whole utterance instead of frames allows
us to refine Batch-Normalization. We also train our own BLSTM-based language model.
Adding a discriminative speaker adaptation leads to further gains. The final system
achieves a word error rate on the six channel real test data of 3.48%. For the
two channel track we achieve 5.96% and for the one channel track 9.34%. This is
the best reported performance on the challenge achieved by a single system, i.e.,
a configuration, which does not combine multiple systems. At the same time, our
system is independent of the microphone configuration. We can thus use the same
components for all three tracks.
