  text: With enhancing digitalization, condition monitoring is used in an increasing
    number of application fields across various industrial sectors. By its application,
    increased reliability as well as reduced risks and costs can be achieved. Based
    on different approaches, technical systems are monitored and measured data is
    analyzed to enable condition-based or predictive maintenance. To this end, machine
    learning approaches are usually implemented to diagnose the health states or predict
    the health index of the monitored system. However, these trained models are often
    black-box models, not intuitively explainable for a human. To overcome this shortcoming,
    a model-based approach based on physics is developed for piezoelectric bending
    actuators. Such a model enables a transparent representation of the system. Moreover,
    the model-based approach is extended by a parameter-estimation to account for
    sudden changes in behavior e. g. caused by occurring cracks.

  text: Entwicklungsprojekte stehen in einem Spannungsfeld von Volatilität, Unsicherheit,
    Komplexität und Ambiguität (VUCA). Resilient Requirements Engineering (RRE) ist
    ein vielversprechender Ansatz, diesen Rahmenbedingungen gerecht zu werden und
    erfolgreich zu entwickeln. Es werden Methoden aus den drei Innovationsfeldern
    des RRE – Vorausschau, Effizienz und Nachhaltigkeit – angewendet, um Effizienzpotenziale
    in der Produktentwicklung zu nutzen und frühzeitig Nachhaltigkeitsdimensionen
    in der Ermittlung von Stakeholderbedürfnissen zu verankern.

  text: "Dispersion is present in every optical setup and is often an undesired effect,
    especially in nonlinear-optical experiments where ultrashort laser pulses are
    needed. Typically, bulky pulse compressors consisting of gratings or prisms are
    used\r\nto address this issue by precompensating the dispersion of the optical
    components. However, these devices are only able to compensate for a part of the
    dispersion (second-order dispersion). Here, we present a compact pulse-shaping
    device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral
    phase delay allowing for a full dispersion control. Furthermore, with specific
    phase encodings, this device can be used to temporally reshape the incident laser
    pulses into more complex pulse forms such as a double pulse. We verify the performance
    of our device by using an SHG-FROG measurement setup together with a retrieval
    algorithm to extract the dispersion that our device applies to an incident laser
    pulse."

  text: Hydrothermal carbonization (HTC) is an efficient thermochemical method for
    the conversion of organic feedstock to carbonaceous solids. HTC of different saccharides
    is known to produce microspheres (MS) with mostly Gaussian size distribution,
    which are utilized as functional materials in various applications, both as pristine
    MS and as a precursor for hard carbon MS. Although the average size of the MS
    can be influenced by adjusting the process parameters, there is no reliable mechanism
    to affect their size distribution. Our results demonstrate that HTC of trehalose,
    in contrast to other saccharides, results in a distinctly bimodal sphere diameter
    distribution consisting of small spheres with diameters of (2.1 ± 0.2) μm and
    of large spheres with diameters of (10.4 ± 2.6) μm. Remarkably, after pyrolytic
    post-carbonization at 1000 °C the MS develop a multimodal pore size distribution
    with abundant macropores > 100 nm, mesopores > 10 nm and micropores < 2 nm, which
    were examined by small-angle X-ray scattering and visualized by charge-compensated
    helium ion microscopy. The bimodal size distribution and hierarchical porosity
    provide an extraordinary set of properties and potential variables for the tailored
    synthesis of hierarchical porous carbons, making trehalose-derived hard carbon
    MS a highly promising material for applications in catalysis, filtration, and
    energy storage devices.

  text: <jats:p>The current investigation shows the feasibility of 316L steel powder
    production via three different argon gas atomisation routes (closed coupled atomisation,
    free fall atomisation with and without hot gas), along with subsequent sample
    production by laser powder bed fusion (PBF-LB). Here, a mixture of pure Fe and
    atomised 316L steel powder is used for PBF-LB to induce a chemical composition
    gradient in the microstructure. Optical microscopy and μ-CT investigations proved
    that the samples processed by PBF-LB exhibit very little porosity. Combined EBSD-EDS
    measurements show the chemical composition gradient leading to the formation of
    a local fcc-structure. Upon heat treatment (1100 °C, 14 h), the chemical composition
    is homogeneous throughout the microstructure. A moderate decrease (1060 to 985
    MPa) in the sample’s ultimate tensile strength (UTS) is observed after heat treatment.
    However, the total elongation of the as-built and heat-treated samples remains
    the same (≈22%). Similarly, a slight decrease in the hardness from 341 to 307
    HV1 is observed upon heat treatment.</jats:p>

  text: "This paper reveals the 3D character of the intermetallic layer at the aluminum–steel
    interface which pops\r\nup above the original sample surface during annealing.
    Popping out of the intermetallics was proven using\r\natomic force microscopy.
    The phase expands out of the plane due to the exothermic formation of the Al5Fe2\r\nphase
    and the feasibility of surface diffusion. Milling by a focused ion beam enabled
    the comparison of the\r\nchemical composition of the surface layer with the bulk
    interface, showing no difference. The growth direction\r\nis both towards aluminum
    and steel — the main diffusion flux is from aluminum towards steel, and the new\r\nintermetallic
    phase emerges at the steel side. The shortage of Al atoms causes a shift of the
    intermetallic as a\r\nwhole towards aluminum."

  text: Faradaic reactions including charge transfer are often accompanied with diffusion
    limitation inside the bulk. Conductive two-dimensional frameworks (2D MOFs) with
    a fast ion transport can combine both - charge transfer and fast diffusion inside
    their porous structure. To study remaining diffusion limitations caused by particle
    morphology, different synthesis routes of Cu-2,3,6,7,10,11-hexahydroxytriphenylene
    (Cu3(HHTP)2), a copper-based 2D MOF, are used to obtain flake- and rod-like MOF
    particles. Both morphologies are systematically characterized and evaluated for
    redox-active Li+ ion storage. The redox mechanism is investigated by means of
    X-ray absorption spectroscopy, FTIR spectroscopy and in situ XRD. Both types are
    compared regarding kinetic properties for Li+ ion storage via cyclic voltammetry
    and impedance spectroscopy. A significant influence of particle morphology for
    2D MOFs on kinetic aspects of electrochemical Li+ ion storage can be observed.
    This study opens the path for optimization of redox active porous structures to
    overcome diffusion limitations of Faradaic processes.

  text: "<jats:title>Abstract</jats:title><jats:p>Three prominent low order implicit
    time integration schemes are the first order implicit Euler-method, the second
    order trapezoidal rule and the second order Ellsiepen method. Its advantages are
    stability and comparatively low computational cost, however, they require the
    solution of a nonlinear system of equations. This paper presents a general approach
    for the construction of third order Runge–Kutta methods by embedding the above
    mentioned implicit schemes into the class of ELDIRK-methods. These will be defined
    to have an <jats:italic>Explicit Last</jats:italic> stage in the general Butcher
    array of <jats:italic>Diagonal Implicit Runge–Kutta</jats:italic> (DIRK) methods,
    with the consequence, that no additional system of equations must be solved. The
    main results—valid also for non-linear ordinary differential equations—are as
    follows: Two extra function calculations are required in order to embed the implicit
    Euler-method and one extra function calculation is required for the trapezoidal-rule
    and the Ellsiepen method, in order to obtain the third order properties, respectively.
    Two numerical examples are concerned with a parachute with viscous damping and
    a two-dimensional laser beam simulation. Here, we verify the higher order convergence
    behaviours of the proposed new ELDIRK-methods, and its successful performances
    for asymptotically exact global error estimation of so-called reversed embedded
    RK-method are shown.\r\n</jats:p>"

  text: <jats:p>The development of automotive components with reduced greenhouse gas
    (GHG) emissions is needed to reduce overall vehicle emissions. Life Cycle Engineering
    (LCE) based on Life Cycle Assessment (LCA) supports this by providing holistic
    information and improvement potentials regarding eco-efficient products. Key factors
    influencing LCAs of automotive components, such as material production, will change
    in the future. First approaches for integrating future scenarios for these key
    factors into LCE already exist, but they only consider a limited number of parameters
    and scenarios. This work aims to develop a method that can be practically applied
    in the industry for integrating prospective LCAs (pLCA) into the LCE of automotive
    components, considering relevant parameters and consistent scenarios. Therefore,
    pLCA methods are further developed to investigate the influence of future scenarios
    on the GHG emissions of automotive components. The practical application is demonstrated
    for a vehicle component with different design options. This paper shows that different
    development paths of the foreground and background system can shift the ecological
    optimum of design alternatives. Therefore, future pathways of relevant parameters
    must be considered comprehensively to reduce GHG emissions of future vehicles.
    This work contributes to the methodological and practical integration of pLCA

  text: Perfect vector vortex beams (PVVBs) have attracted considerable interest due
    to their peculiar optical features. PVVBs are typically generated through the
    superposition of perfect vortex beams, which suffer from the limited number of
    topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable
    and has not been reported. We propose and experimentally demonstrate hybrid grafted
    perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs
    are generated through the superposition of grafted perfect vortex beams with a
    multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant
    rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB
    includes different GPVVBs in the same beam, adding more design flexibility. Moreover,
    these beams are dynamically controlled with a rotating half waveplate. The generated
    dynamic GPVVBs may find applications in the fields where dynamic control is in
    high demand, including optical encryption, dense data communication, and multiple
    particle manipulation.

  text: <jats:p>This work reports a fully guided setup for single-mode squeezing on
    integrated titanium-indiffused periodically poled nonlinear resonators. A continuous-wave
    laser beam is delivered and the squeezed field is collected by single-mode fibers;
    up to −3.17(9) dB of useful squeezing is available in fibers. To showcase the
    usefulness of such a fiber-coupled device, we applied the generated squeezed light
    in a fiber-based phase sensing experiment, showing a quantum enhancement in the
    signal-to-noise ratio of 0.35 dB. Moreover, our investigation of the effect of
    photorefraction on the cavity resonance condition suggests that it causes system
    instabilities at high powers.</jats:p>

  text: "<jats:p>While FPGA accelerator boards and their respective high-level design
    tools are maturing, there is still a lack of multi-FPGA applications, libraries,
    and not least, benchmarks and reference implementations towards sustained HPC
    usage of these devices. As in the early days of GPUs in HPC, for workloads that
    can reasonably be decoupled into loosely coupled working sets, multi-accelerator
    support can be achieved by using standard communication interfaces like MPI on
    the host side. However, for performance and productivity, some applications can
    profit from a tighter coupling of the accelerators. FPGAs offer unique opportunities
    here when extending the dataflow characteristics to their communication interfaces.</jats:p>\r\n
    \         <jats:p>In this work, we extend the HPCC FPGA benchmark suite by multi-FPGA
    support and three missing benchmarks that particularly characterize or stress
    inter-device communication: b_eff, PTRANS, and LINPACK. With all benchmarks implemented
    for current boards with Intel and Xilinx FPGAs, we established a baseline for
    multi-FPGA performance. Additionally, for the communication-centric benchmarks,
    we explored the potential of direct FPGA-to-FPGA communication with a circuit-switched
    inter-FPGA network that is currently only available for one of the boards. The
    evaluation with parallel execution on up to 26 FPGA boards makes use of one of
    the largest academic FPGA installations.</jats:p>"
