  text: The layered structure of Additive Manufacturing processes results in a stair-
    stepping effect of the surface topographies. In general, the impact of this effect
    strongly depends on the build angle of a surface, whereas the overall surface
    roughness is additionally caused by the resolution of the specific AM process.
    The aim of this work is the prediction of the surface quality in dependence of
    the building orientation of a part. These results can finally be used to optimize
    the orientation to get a desired surface quality. As not all parts of the component
    surface are equally important, a preselection of areas can be used to improve
    the overall surface quality of relevant areas. The model uses the digital AMF
    format of a part. Each triangle is assigned with a roughness value and by testing
    different orientations the best one can be found. This approach needs a database
    for the surface qualities. This must be done separately for each Additive Manufacturing
    process and is shown exemplarily with a surface topography simulation for the
    laser sintering process.

  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: Wire bonding has been an established packaging technology for decades. When
    introducing copper as wire material for high power applications, adaptations to
    the bonding process and to machines became necessary. Here, challenges occur due
    to the stiffer wire material and changing oxide layers on the contact partners.
    To achieve sufficient process stability, a clean bond area is required, which
    can only be achieved with high shear stresses in the contact partners surfaces.
    These necessitate high normal forces to plastically deform the wire and substrate.
    To achieve such high stresses in the contact area, the bonding tool needs to be
    able to transmit the needed tangential forces to the top side of the wire. The
    wire itself performs a shear movement and transmits the force into the contact
    area to clean the contaminant and oxide layers and to level the desired bond surfaces.
    The main function of the tool is to transmit these forces. If the bond tool can
    only transmit low forces in the direction of excitation, the parameter space for
    a stable bond process is severely restricted. Here, a modeling approach to estimate
    how well different tool shapes meet the demand of transmitting high tangential
    forces is presented. The model depends on wire deformation and thus on the ultrasonic
    softening effect.

  text: The transportation of dry fine powders is an emerging technologic task, as
    in biotechnology, pharmaceutical or coatings industry particle sizes of processed
    powders are getting smaller and smaller. Fine powders are primarily defined by
    the fact that adhesive and cohesive forces outweigh the weight forces. This leads
    to mostly unwanted agglomeration (clumping) and adhesion to surfaces, what makes
    it more difficult to use conventional conveyor systems (e. g. pneumatic or vibratory
    conveyors) for transport. A rather new method for transporting these fine powders
    is based on ultrasonic vibrations, which are used to reduce friction and adhesion
    between powder and the substrate. One very effective set-up consists of a pipe,
    which vibrates harmoniously in axial direction at low frequency combined with
    a pulsed radial high frequency vibration. The high frequency vibration accelerates
    the particles perpendicular to the surface of the pipe, which in average leads
    to lower normal and thereby smaller friction force. With coordinated friction
    manipulation the powder acceleration can be varied so that the powder may be greatly
    accelerated and only slightly decelerated in each excitation period of the low
    frequency axial vibration of the pipe. The amount of powder flow is adjustable
    by vibration amplitudes, frequencies, and pulse rate, which makes the device versatile
    for comparable high volume and fine dosing using one setup. Within this contribution
    an experimental set-up consisting of a pipe, a solenoid actuator for axial vibration
    and a piezoelectric actuator for the radial high frequency vibration is described.
    An analytical model is shown, that simulates the powder velocity. Finally, simulation
    results are validated by experimental data for different driving parameters such
    as amplitude of low frequency vibration, pipe material and inclination angle.

  text: Ultrasonic wire bonding is a common technology for connecting electrodes of
    electronic components like power modules. Nowadays, bond connections are often
    made of copper instead of aluminum due to its thermal and mechanical assets. One
    of the main cost factors in the wire bonding process is the acquisition cost of
    consumables such as bonding tools. For copper wire bonding tool lifetime is much
    lower than for aluminium bonding. This paper presents a micro wear model for wedge/wedge
    bonding tools that was validated by observing wear patterns with a scanning electron
    microscope. The wear coefficient is determined in long-term bonding tests. The
    application of Fleischer´s wear approach incorporating frictional power to a finite
    element simulation of the bonding processes is used to shift element nodes depending
    on the rising frictional power for finite element modeling. The presented simulation
    method can be used to take tool wear into consideration for creating tools with
    increased lifetime. This enables the production of reliable bond connections using
    heavy as well as thin wire of any material. The paper discusses the predominant
    influences of wear on the main tool functions and their changes over tool life.
    Furthermore, the influence of the tool groove angle on the tool wear was investigated.
    One of the main results is that the wear is largest during the last phase of each
    bonding process, when the contact area between tool and wire is largest.

  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: Typical optical integrated circuits combine elements, like straight and curved
    waveguides, or cavities, the simulation and design of which is well established
    through numerical eigenproblem-solvers. It remains to predict the interaction
    of these modes. We address this task by a ”Hybrid” variant (HCMT) of Coupled Mode
    Theory. Using methods from finite-element numerics, the optical properties of
    a circuit are approximated by superpositions of eigen-solutions for its constituents,
    leading to quantitative, low-dimensional, and interpretable models in the frequency
    domain. Spectral scans are complemented by the direct computation of supermode
    properties (spectral positions and linewidths, coupling-induced phase shifts).
    This contribution outlines the theoretical background, and discusses briefly limitations
    and implementational details, with the help of an example of a 2-D coupled-resonator-optical-waveguide
    configuration.

  text: 'This contribution investigates Direction of Arrival (DoA) estimation using
    linearly arranged microphone arrays. We are going to develop a model for the DoA
    estimation error in a reverberant scenario and show the existence of a bias, that
    is a consequence of the linear arrangement and limited field of view (FoV) bias:
    First, the limited FoV leading to a clipping of the measurements, and, second,
    the angular distribution of the signal energy of the reflections being non-uniform.
    Since both issues are a consequence of the linear arrangement of the sensors,
    the bias arises largely independent of the kind of DoA estimator. The experimental
    evaluation demonstrates the existence of the bias for a selected number of DoA
    estimation methods and proves that the prediction from the developed theoretical
    model matches the simulation results.'

  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.

  text: 'Following the direction pioneered by Fiat and Papadimitriou in their 2010
    paper [12], we study the complexity of deciding the existence of mixed equilibria
    for minimization games where players use valuations other than expectation to
    evaluate their costs. We consider risk-averse players seeking to minimize the
    sum V=E+R of expectationE and a risk valuationR of their costs; R is non-negative
    and vanishes exactly when the cost incurred to a player is constant over all choices
    of strategies by the other players. In a V-equilibrium, no player could unilaterally
    reduce her cost.Say that V has the Weak-Equilibrium-for-Expectation property if
    all strategies supported in a player''s best-response mixed strategy incur the
    same conditional expectation of her cost. We introduce E-strict concavity and
    observe that every E-strictly concave valuation has the Weak-Equilibrium-for-Expectation
    property. We focus on a broad class of valuations shown to have the Weak-Equilibrium-for-Expectation
    property, which we exploit to prove two main complexity results, the first of
    their kind, for the two simplest cases of the problem:• Two strategies: Deciding
    the existence of a V-equilibrium is strongly NP-hard for the restricted class
    of player-specific scheduling games on two ordered links [22], when choosing R
    as (1)Var (variance), or (2)SD (standard deviation), or (3) a concave linear sum
    of even moments of small order.• Two players: Deciding the existence of a V-equilibrium
    is strongly NP-hard when choosing R as (1)γ⋅Var, or (2)γ⋅SD, where γ>0 is the
    risk-coefficient, or choosing V as (3) a convex combination of E+γ⋅Var and the
    concave ν-valuationν−1(E(ν(⋅))), where ν(x)=xr, with r≥2. This is a concrete consequence
    of a general strong NP-hardness result that only needs the Weak-Equilibrium-for-Expectation
    property and a few additional properties for V; its proof involves a reduction
    with a single parameter, which can be chosen efficiently so that each valuation
    satisfies the additional properties.'
