text: "Abstract\r\n Purpose\r\n
\ It has been reported that there is no correlation between
anterior tibia translation (ATT) in passive and dynamic situations. Passive ATT
(ATTp) may be different to dynamic ATT (ATTd) due to muscle activation patterns.
This study aimed to investigate whether muscle activation during jumping can control
ATT in healthy participants.\r\n \r\n
\ Methods\r\n ATTp
of twenty-one healthy participants was measured using a KT-1000 arthrometer. All
participants performed single leg hops for distance during which ATTd, knee flexion
angles and knee flexion moments were measured using a 3D motion capture system.
During both tests, sEMG signals were recorded.\r\n \r\n
\ Results\r\n A
negative correlation was found between ATTp and the maximal ATTd (r = − 0.47,
p = 0.028). An N-Way ANOVA showed that larger semitendinosus
activity was seen when ATTd was larger, while less biceps femoris activity and
rectus femoris activity were seen. Moreover, larger knee extension moment, knee
flexion angle and ground reaction force in the anterior-posterior direction were
seen when ATTd was larger.\r\n \r\n
\ Conclusion\r\n Participants
with more ATTp showed smaller ATTd during jump landing. Muscle activation did
not contribute to reduce ATTd during impact of a jump-landing at the observed
knee angles. However, subjects with large ATTp landed with less knee flexion and
consequently showed less ATTd. The results of this study give information on how
healthy people control knee laxity during jump-landing.\r\n \r\n
\ Level of evidence\r\n III\r\n

text: Ultrasonic wire bonding is a process to form electrical connections in electronics
well established industry. Typically, a clamping tool is pressed on the wire and
forced to vibrate at relative high frequency 40 to 100 kHz. The ultrasonic vibration
is transmitted through the wire into the interface between wire and substrate.
Due to frictional processes, contamination like oxide layers are removed from
the contact zone, the surface roughness is reduced, and with increasing bond duration
an metallic connection of wire and substrate is established. It is known that
the amount of ultrasonic energy over time directly influences the strength and
reliability of the bond connection, but the determination of optimum bond parameters
is still a challenging experimental task. For this, in the past different model
approaches have been presented, to calculate the bond quality by simulation. Measuring
the friction between wire and substrate to validate these models is a challenging
task at ultrasonic bonding frequency. Therefore a versatile test rig for bonding
experiments at frequencies lower than 1 kHz is setup to get detailed insight into
the different phases of the connection process. It includes a piezoelectric force
sensor for the measurement of the three-dimensional process forces, an electrodynamic
shaker for the vibration excitation and a conventional tension-compression testing
machine to apply the bond normal force. Using this test rig, it is possible to
observe the different phases of bond formation in detail, validate and enhance
existing models and finally optimize bond parameters for different processes.

text: As a result of lightweight design, increased use is being made of high-strength
steel and aluminium in car bodies. Self-piercing riveting is an established technique
for joining these materials. The dissimilar properties of the two materials have
led to a number of different rivet geometries in the past. Each rivet geometry
fulfils the requirements of the materials within a limited range. In the present
investigation, an improved rivet geometry is developed, which permits the reliable
joining of two material combinations that could only be joined by two different
rivet geometries up until now. Material combination 1 consists of high-strength
steel on both sides, while material combination 2 comprises aluminium on the punch
side and high-strength steel on the die side. The material flow and the stress
and strain conditions prevailing during the joining process are analysed by means
of numerical simulation. The rivet geometry is then improved step-by-step on the
basis of this analysis. Finally, the improved rivet geometry is manufactured and
the findings of the investigation are verified in experimental joining tests.

text: The simulation of complex engineering components and structures under
loads requires the formulation and adequate calibration of appropriate material
models. This work introduces an optimisation-based scheme for the calibration
of viscoelastic material models that are coupled to gradient-enhanced damage in
a finite strain setting. The parameter identification scheme is applied to a self-diagnostic
poly(dimethylsiloxane) (PDMS) elastomer, where so-called mechanophore units are
incorporated within the polymeric microstructure. The present contribution, however,
focuses on the purely mechanical response of the material, combining experiments
with homogeneous and inhomogeneous states of deformation. In effect, the results
provided lay the groundwork for a future extension of the proposed parameter identification
framework, where additional field-data provided by the self-diagnostic capabilities
can be incorporated into the optimisation scheme.

text: "AbstractRecent experimental work has revealed
that interstitial fluid flow can mobilize two types of tumor cell migration mechanisms.
One is a chemotactic-driven mechanism where chemokine (chemical component) bounded
to the extracellular matrix (ECM) is released and skewed in the flow direction.
This leads to higher chemical concentrations downstream which the tumor cells
can sense and migrate toward. The other is a mechanism where the flowing fluid
imposes a stress on the tumor cells which triggers them to go in the upstream
direction. Researchers have suggested that these two migration modes possibly
can play a role in metastatic behavior, i.e., the process where tumor cells are
able to break loose from the primary tumor and move to nearby lymphatic vessels.
In Waldeland and Evje (J Biomech 81:22–35, 2018), a mathematical cell–fluid model
was put forward based on a mixture theory formulation. It was demonstrated that
the model was able to capture the main characteristics of the two competing migration
mechanisms. The objective of the current work is to seek deeper insight into certain
qualitative aspects of these competing mechanisms by means of mathematical methods.
For that purpose, we propose a simpler version of the cell–fluid model mentioned
above but such that the two competing migration mechanisms are retained. An initial
cell distribution in a one-dimensional slab is exposed to a constant fluid flow
from one end to the other, consistent with the experimental setup. Then, we explore
by means of analytical estimates the long-time behavior of the two competing migration
mechanisms for two different scenarios: (i) when the initial cell volume fraction
is low and (ii) when the initial cell volume fraction is high. In particular,
it is demonstrated in a strict mathematical sense that for a sufficiently low
initial cell volume fraction, the downstream migration dominates in the sense
that the solution converges to a downstream-dominated steady state as time elapses.
On the other hand, with a sufficiently high initial cell volume fraction, the
upstream migration mechanism is the stronger in the sense that the solution converges
to an upstream-dominated steady state.\r\n"

text: The increasingly simulation-driven design process of ultrasonic transducers
requires several reliable parameters for the description of the material behaviour.
Exact results can only be achieved when a single specimen is used in the identification
process, which typically is prone to the problem of low sensitivities to certain
material parameters and thus high uncertainties. Therefore, a custom electrode
topology for increased sensitivity is proposed for a piezoceramic disc. The thereupon
conducted measurements of the electric impedance can be used as a starting point
for an inverse approach where an equivalent simulation model is used to identify
fitting material parameters. An optimisation strategy based on a preliminary sensitivity
analysis is presented that leads to a good agreement between measurement and simulation.
Furthermore, the proposed measurement procedure is able to evaluate the quality
of the simulation model. Hence, different frequency-dependent damping models are
presented and evaluated.

text: Although there are numerous design methodologies for the LLC resonant converter,
they often do not consider the possibility of input voltage adjustment. In the
proposed concept, a modular multi-level converter (MMC) is used to step-down the
three-phase medium voltage of 10 kV, and provide up to 1 MW of pure DC power to
the load consisting of electrolyzers for hydrogen generation. Therefore, each
module is extended by an LLC resonant converter to adapt to the specific electrolyzers
DC voltage range of 142...220 V and to provide galvanic isolation. In order to
achieve a high efficiency for a wide range of load conditions, the input voltage
of the LLC converter is adjusted between 600 V and 770 V while operating at resonance
or close to resonance. The parameters of the 11kW LLC resonant converter with
an integrated leakage inductance are systematically optimized to maximize the
efficiency for all loads while achieving zero-voltage switching. For a fast estimation
of eddy current losses, a new method is proposed, which uses a single FEM simulation
to fit newly developed loss equations. The calculated average efficiency is 97.8%.
The prototype of the LLC converter reaches a peak efficiency of over 98% at resonance
at half load which is similar to the precalculated value.

text: In this paper we present a new system concept for an optoelectronic wireless
phased array system. Like in a conventional phased array system with optical carrier
distribution, optical fibers are used to distribute the carrier from the basestation
to the wireless frontends. However in contrast to prior concepts, we propose to
use an optical IQ return path from the wireless frontends back to the basestation.
Furthermore, we reuse the optical carrier signal for the IQ return path which
allows to avoid local oscillator lasers in the wireless frontends and reduces
the hardware effort significantly. The system concept allows to integrate all
components of an optoelectronic wireless frontend in a single chip using silicon
photonics technology.

text: Radial shaft sealing rings (RSSR) are important machine elements used in rotating
and oil lubricated systems. Their main task is to prevent oil from exiting the
system and dirt particles from entering the system. When this function is not
fulfilled, a leakage can occur and cause excessive damage after certain operating
times, such as gear failure due to insufficient lubrication. This is the reason
for the high level of current research interest in seals. The sealing function
of RSSR occurs in the contact area between the sealing lip and the shaft. The
contact takes place over a very small contact width of approximately 1 μm.
These extremely small dimensions and the complex relationships between the functional
influencing variables on the radial shaft sealing system make it difficult to
simulate wear on the sealing ring. The energetic consideration of the wear process
offers the possibility of quantifying influencing variables more easily by their
energetic contribution, which can be determined experimentally. Based on experimentally
measured total friction moments, and with the help of a semi-analytical (SA) solid
contact model based on the half-space theory, this paper presents a modelling
approach for the calculation of wear at the sealing ring. The model presented
in this work differs from the existing models in two ways. The first particularity
is the coupling of SA method with finite element method (FEM) for the resolution
of the contact between the sealing lip and the shaft, allowing a fine discretization
of the contact zone (by SA method) and the consideration of the structural behavior
(by FE method). The SA method compared to the commonly used FEM presents a great
saving in computation time. The second particularity is the use of the real data
obtained during the wear tests. Most existing simulation models are based purely
on contact pressure. This means that through the contact pressure obtained by
simulation and a given sliding distance value, a friction energy will be estimated
which will be used in a next step using a wear model such as Archad’s to
calculate the wear rate. In this publication the value of friction energy was
obtained directly on an experimental basis and a more appropriate wear law, such
as Fleischer’s, taking into account the friction conditions, was used to
estimate the wear rate.

text: Regarding the increasing demand in seal lifetime and energy efficiency, a
detailed microscopic simulation is necessary—as an addition to experimental investigations—to
better understand and improve radial shaft seals. For this purpose, typically
thermoelastohydrodynamic lubrication (TEHL) simulations are used. The published
models range from rather simple elastohydrodynamic lubrication (EHL) models to
very sophisticated TEHL models. Only very few models take into account the roughness
or microstructure of both contact surfaces, though, since this would require the
consideration of transient effects. In this article, a transient TEHL model for
the contact of radial shaft seals is presented. Studies of the sealing contact
are conducted, and the possibility of investigating shaft microstructuring is
shown.
