text: 'This study evaluates four widely used fracture simulation methods,
comparing their computational expenses and implementation complexities within
the finite element (FE) framework when employed on heterogeneous solids. Fracture
methods considered encompass the intrinsic cohesive zone model (CZM) using zero-thickness
cohesive interface elements (CIEs), the standard phase-field fracture (SPFM) approach,
the cohesive phase-field fracture (CPFM) approach, and an innovative hybrid model.
The hybrid approach combines the CPFM fracture method with the CZM, specifically
applying the CZM within the interface zone. The finite element model studied is
characterized by three specific phases: inclusions, matrix, and the interface
zone. This case study serves as a potential template for meso- or micro-level
simulations involving a variety of composite materials. The thorough assessment
of these modeling techniques indicates that the CPFM approach stands out as the
most effective computational model, provided that the thickness of the interface
zone is not significantly smaller than that of the other phases. In materials
like concrete, which contain interfaces within their microstructure, the interface
thickness is notably small when compared to other phases. This leads to the hybrid
model standing as the most authentic finite element model, utilizing CIEs within
the interface to simulate interface debonding. A significant finding from this
investigation is that within the CPFM method, for a specific interface thickness,
convergence with the hybrid model can be observed. This suggests that the CPFM
fracture method could serve as a unified fracture approach for multiphase materials
when a specific interfacial thickness is used. In addition, this research provides
valuable insights that can advance efforts to fine-tune material microstructures.
An investigation of the influence of interfacial material properties, voids, and
the spatial arrangement of inclusions shows a pronounced effect of these parameters
on the fracture toughness of the material.'

text: We present a general and intuitive ambiguity model for intersections, junctions
and other structures in binary edge images. The model is combined with edge tracing,
where edges are ordered sequences of connected pixels. The objective is to provide
a versatile preprocessing method for tasks such as figure-ground segmentation,
object recognition, topological analysis, etc. By using only a small set of straightforward
principles, the results are intuitive to describe. This helps to implement subsequent
processing steps, such as resolving ambiguous edge connections at junctions. By
using an augmented edge map, neighboring edges can be directly accessed using
quick local search operations. The edge tracing uses recursion, which leads to
compact programming code. We explain our algorithm using pseudocode, compare it
with related methods, and show how simple modular postprocessing steps can be
used to optimize the results. The complete algorithm, including all data structures,
requires less than 50 lines of pseudocode. We also provide a C++ implementation
of our method.

text: Die Forschung zum kindlichen Wortlernen hat in den letzten Jahren aufgezeigt,
dass der Erwerb eines neuen Wortes durch Prozessualität gekennzeichnet ist. Ein
aktuelles Forschungsinteresse richtet sich in diesem Zusammenhang auf die Frage,
inwieweit die längerfristigen kontextuellen Gegebenheiten diesen Lernprozess beeinflussen
und ob der Erwerbsprozess durch stabile kontextuelle Bedingungen oder durch kontextuelle
Variabilität begünstigt wird. Während sich bisherige Arbeiten in dieser Hinsicht
vornehmlich auf isolierte Kontextfaktoren konzentrierten, rückt dieser Band die
rahmende soziale Handlung und die beteiligten interaktiven Prozesse in den Mittelpunkt.
Er zielt darauf ab, die Auswirkungen langfristiger Kontextbedingungen auf das
Wortlernen von Vorschulkindern mit sozialen Robotern und menschlichen Interaktionspartnern
systematisch zu untersuchen.

text: "In quantitativen Fragebogenstudien arbeiten Forschende mit großen Datensätzen,
bei deren Erhebung sie häufig auf Online-Fragebögen anstelle der klassischen Paper-Pencil-Fragebögen
setzen. Forschende bevorzugen diese Art der Datenerhebung, da die Daten direkt
nach der Eingabe digitalisiert sind; zu\r\nbedenken ist aber auch, dass Online-Fragebögen
komplexer sind und mehr Vorbereitung benö'gen als Paper-Pencil-Fragebögen.\r\n\r\nIn
diesem Workshop werden die Tools LimeSurvey und SoSci Survey vorgestellt, wobei
der Fokus zum einen auf „klassischen“ Umfragen (LimeSurvey) und zum anderen auf
Experimenten wie Akzeptabilitätsurteilen (SoSci Survey) liegen wird. Außerdem
werden wir Vor- und Nachteile, Darstellungs- und Designanforderungen sowie Dos
und Don’ts bei der Erstellung von Online-Fragebögen behandeln. Wenn Sie bereits
einen eigenen Fragebogen erstellt haben und diesen gerne in LimeSurvey oder SoSci
Survey erstellen möchten, bringen Sie ihn gerne zum Workshop mit.\r\n\r\nZur Vorbereitung
auf den Workshop sollten Sie einen Account bei LimeSurvey (https://www.limesurvey.org/de)
und/oder SoSci Survey (https://www.soscisurvey.de/) erstellen.\r\nSollte Ihre
Universität über eine eigene LimeSurvey- oder SoSci Survey-Lizenz verfügen, können
Sie auch dort einen Account anlegen. Empfehlenswert ist ferner, sich im Vorfeld
das DGFF-Kolleg-Webinar von Henning Rossa zum Thema Fragebogen (https://www.dgff.de/fragebogen-henning-rossa/)
anzuschauen."

text: Background/Purpose
Return to sport decision-making may be improved by assessing an athlete’s
ability to coordinate movement with opponents in sport. The purpose was to investigate
whether previous injuries associated with female soccer players’ interpersonal
coordination during a collision avoidance task. The authors hypothesized that
external perturbations would disrupt the strength and stability of coordinated
movement, and that individuals with a history of injury would be less likely to
recover coordinated movement.
Study Design Cross-Sectional
Methods Nine female athletes
with a history of lower extremity injuries and nine without injuries were paired
into dyads. Each dyad completed twenty trials of an externally paced collision-avoidance
agility task with an unanticipated perturbation. Participant trajectories were
digitized and analyzed using cross-recurrence quantification analysis (CRQA) to
determine the strength and stability of interpersonal coordination dynamics. Trials
in which participants with injury history assumed leader or follower roles within
each dyad were then used to study how dyadic coordination varied across task stages
(early, perturbation, and late) using linear mixed effect models. Cohen’s d effect
sizes were calculated to demonstrate magnitude of differences. In exploratory
analysis, psychological readiness (i.e., self-reported knee functioning, fear
of injury, and risk-taking propensity) was evaluated for their association with
leader-follower status. Results
Perturbation disrupted the strength (R2=0.65, p<0.001, early=49.7±1.7,
perturbation=41.1±1.7, d=0.39) and stability (R2=0.71, p < 0.001, early=65.0±1.6,
perturbation=58.0±1.7, d=0.38) of interpersonal coordination regardless of leader-follower
status. Individuals with injury history failed to restore coordination after the
perturbation compared to control participants (injury=44.2.0±2.1, control=50.8±2.6,
d=0.39). Neither demographic nor psychological measures were associated with leader-follower
roles (B=0.039, p=0.224). Conclusion
Individuals with a history of lower extremity injury may have a diminished
ability to adapt interpersonal coordination to perturbations, possibly contributing
to a higher risk of re-injury.

text: "\r\n Context\r\n Although
the landing phases of the single-leg hop for distance (SLHD) are commonly assessed,
limited work reflects how the take-off phase influences hop performance in patients
with anterior cruciate ligament reconstruction (ACLR).\r\n \r\n
\ \r\n Objective\r\n
\ To compare trunk and lower extremity biomechanics between
individuals with ACLR and matched uninjured controls during take-off of the SLHD.\r\n
\ \r\n \r\n Design\r\n
\ Cross-sectional study design.\r\n \r\n
\ \r\n Setting\r\n
\ Laboratory setting.\r\n \r\n
\ \r\n Patients or Other Participants\r\n
\ Sixteen individuals with ACLR and 18 uninjured controls.\r\n
\ \r\n \r\n Main
Outcome Measure(s)\r\n Normalized quadriceps
isokinetic torque, hop distance, and respective limb symmetry indices were collected
for each participant. Sagittal and frontal kinematics and kinetics of the trunk,
hip, knee, and ankle as well as vertical and horizontal ground reaction forces
were recorded for loading and propulsion of the take-off phase of the SLHD.\r\n
\ \r\n \r\n Results\r\n
\ Those with ACLR had weaker quadriceps peak torque in
the involved limb (P = .001) and greater strength asymmetry (P < .001)
than control individuals. Normalized hop distance was not statistically different
between limbs or between groups (P > .05), and hop distance symmetry was
not different between groups (P > .05). During loading, the involved limb
demonstrated lesser knee flexion angles (P = .030) and knee power (P = .007) than
the uninvolved limb and lesser knee extension moments than the uninvolved limb
(P = .001) and controls (P = .005). During propulsion, the involved limb demonstrated
lesser knee extension moment (P = .027), knee power (P = .010), knee (P = .032)
and ankle work (P = .032), and anterior-posterior ground reaction forces (P =
.047) and greater knee (P = .016) abduction excursions than the uninvolved limb.\r\n
\ \r\n \r\n Conclusions\r\n
\ Between-limb differences in SLHD take-off suggest a
knee underloading strategy in the involved limb. These results provide further
evidence that distance covered during SLHD assessment can overestimate function
and fail to identify compensatory biomechanical strategies.\r\n "

text: AbstractPurposeThe
study aimed to evaluate the impact of neurocognitive reliance on jump distance
and lower extremity kinematics in individuals who had undergone anterior cruciate
ligament reconstruction (ACLR). This was achieved by comparing hop performance
under standard and neurocognitive conditions.MethodsThirty‐two
patients after ACLR and 32 healthy controls (CTRL) participated. Both groups performed
a single‐leg hop for distance (SLHD) and two neurocognitive hop tests, each designed
to evaluate distinct aspects of neurocognition. The neurocognitive tests included
the reaction SLHD (R‐SLHD), measuring reaction to a central stimulus and working
memory SLHD (WM‐SLHD) assessing response to a memorized stimulus amidst distractor
stimuli. Distances were assessed for the three‐hop tests. In addition, joint kinematics
were collected to calculate lower extremity coordination of the lower extremity.
SLHD performance was defined as the mean hop distance per condition per leg for
each participant and was analyzed using a mixed ANOVA with condition and leg as
the within‐subjects factors and the group (ACLR or CTRL) as the between‐subjects
factor. Differences in joint coordination variability were analyzed using two‐sample
t‐test statistical parametric mapping (SPM) with linear
regression.ResultsThe
WM‐SLHD resulted in a significantly decreased jump distance compared with the
standard hop test both for ACLR and CTRL. Furthermore, the leg difference within
the ACLR group increased under higher cognitive load as tested with the WM‐SLHD,
indicating leg‐specific adaptations in lower extremity coordination.ConclusionsNeurocognitive
single‐leg hop tests resulted in reduced jump distance in CTRL and ACLR. The neurocognitive
hop test revealed changes in coordination variability for the CTRL and the uninjured
leg of ACLR individuals, whereas the injured leg's coordination variability remained
unaltered, suggesting persistent cognitive control of movements post‐ACLR.Level

EM, Gokeler, A, Broekhaar, DC, and Cortes, N. Motivation unraveled: giving choice
to football players to improve anterior cruciate ligament injury prevention. J Strength Cond Res XX(X): 000–000, 2024—Providing
athletes some control over a training session facilitates motor skill acquisition.
This is a promising concept to use in anterior cruciate ligament (ACL) injury
prevention, as the key for risk reduction is to improve quality of movement. The
goal of this study was to better understand why improved motor learning occurred
when football players had the opportunity to choose when to receive feedback when
practicing sidestep cutting (SSC) movements. Healthy male recreational football
players (n = 22, 22.9 ± 1.7 years, 185.5
± 7.2 cm, 79.3 ± 9.2 kg) were included and assigned to the self-control (SC) or
the yoked (YK) group. The players performed anticipated and unanticipated SSC.
They received video instructions and were instructed to “copy the movement of
the model to the best of their ability.” During the training blocks, the SC group
could ask for feedback, whereas the YK group could not. Cutting movement assessment
scores (CMAS) were measured to test quality of movement and the Intrinsic Motivation
Inventory was administered to measure constructs of motivation. In the anticipated
condition, SC group showed better scores in immediate post and the retention test
compared with pretest (p < 0.001),
whereas the YK group showed worse scores in the retention test compared with immediate
posttest (p = 0.001). Perceived competence
(p = 0.017) and self-efficacy (p = 0.032) were consistent factors that correlated
with improved CMAS in the SC group. This has given us innovative insights into
underlying mechanisms optimizing the quality of movement, necessary to improve
current ACL injury prevention approaches."

text: Background In
basketball, changing direction is one of the primary mechanisms of anterior cruciate
ligament (ACL) injury, often occurring within complex game situations with high
cognitive demands. It is unknown how visual attention affects sidestep cutting
kinematics during the entire energy absorption phase of the cut in an ecologically
valid environment. Purpose
The purpose of this research was to study the effect of added cognitive
load, in the form of increased visual attentional demands, on sidestep cutting
kinematics during the energy absorption phase of the cut in an ecologically valid
environment. Study
Design Crossover Study
Methods Fifteen male basketball players (aged
22.1 ± 2.3) performed ten sidestep cutting movements without (BASE) and with (VIS)
a visual attention dual task. 3D kinematics of the hip, knee and ankle were recorded
utilizing Xsens IMU motion capture. Temporal kinematics were analyzed using Statistical
Parametric Mapping. Discrete time point kinematics were additionally analyzed
at initial contact (IC) and at peak knee flexion utilizing paired t-tests. Effect
sizes were calculated. Results
Hip flexion was significantly reduced in the VIS condition compared to
the BASE condition (p<0.01), including at IC (VIS 35.0° ± 7.2°, BASE 40.7°
± 4.9°, p=0.02, d=0.92) and peak (VIS 37.8° ± 9.7°, BASE 45.5° ± 6.9°, p=0.001,
d=0.90). Knee flexion was significantly reduced in the VIS condition, in comparison
to the BASE condition (p<0.01), at peak (VIS 59.9° ± 7.5°, BASE 64.1° ± 7.4°,
p=0.001, d=0.55). Conclusion
The addition of visual attention during sidestep cutting altered lower
limb kinematics, which may increase ACL injury risk. It is suggested that ACL
injury risk screening and prevention should include sidestep cutting with visual
attentional demands, in order to mimic the cognitive demands of the sports environment.

text: Laboratory studies have limitations in screening for anterior cruciate
ligament (ACL) injury risk due to their lack of ecological validity. Machine learning
(ML) methods coupled with wearable sensors are state-of-art approaches for joint
load estimation outside the laboratory in athletic tasks. The aim of this study
was to investigate ML approaches in predicting knee joint loading during sport-specific
agility tasks. We explored the possibility of predicting high and low knee abduction
moments (KAMs) from kinematic data collected in a laboratory setting through wearable
sensors and of predicting the actual KAM from kinematics. Xsens MVN Analyze and
Vicon motion analysis, together with Bertec force plates, were used. Talented
female football (soccer) players (n = 32, age 14.8 ± 1.0 y, height 167.9 ± 5.1
cm, mass 57.5 ± 8.0 kg) performed unanticipated sidestep cutting movements (number
of trials analyzed = 1105). According to the findings of this technical note,
classification models that aim to identify the players exhibiting high or low
KAM are preferable to the ones that aim to predict the actual peak KAM magnitude.
The possibility of classifying high versus low KAMs during agility with good approximation
(AUC 0.81–0.85) represents a step towards testing in an ecologically valid environment.

text: AbstractAlthough achievement situations trigger
multiple emotions and learners experience both negative and positive emotions
simultaneously, procrastination research typically examines isolated relationships
between specific emotions and procrastination. The potential interplay of negative
and positive emotions regarding procrastination is often overlooked, although
this perspective can shed light on their dynamic relationships. Moreover, past
studies primarily address the behavioral aspect of procrastination (delay) while
overlooking its emotional facet (subjective discomfort), albeit this differentiation
could enhance understanding of procrastination and its correlates. The present
study explores the understudied interplay of the two most frequently experienced
negative (anxiety) and positive (hope) exam-related emotions regarding students’
procrastination tendencies with differentiated behavioral and emotional dimensions.
The study analyzes cross-sectional data from two independent studies (Nstudy1
= 266, Nstudy2 = 468) conducted
in Germany among university students. Latent profile analyses (LPA) reveal three
similar profiles across both studies—High Anxiety–Low Hope,
Low Anxiety–High Hope and Moderate Anxiety–Moderate
Hope— and two study-specific profiles namely, Low Anxiety–Moderate
Hope (Study 1) and High Anxiety–Moderate Hope
(Study 2). Females compared to males are more likely to belong to the anxiety-dominated
profiles. Overall, students in anxiety-dominated profiles report higher scores
whereas students in hope-dominated profiles report lower scores on both behavioral
and emotional dimensions of academic procrastination. This study advances an integrated
approach that incorporates the combined effects of both negative and positive
emotions concerning procrastination. Findings further inform research efforts
towards identifying risk and protective emotional factors to develop tailored
intervention against academic procrastination.

text: Der Permanentmagnet-Synchronmotor (PMSM) ist aufgrund seiner hohen Leistungs-
und Drehmomentdichte bezogen auf Volumen und Gewicht ein häufig verwendeter Traktionsmotor
in Automobilanwendungen. Jene Charakteristika werden jedoch maßgeblich durch Temperaturhöchstwerte
begrenzt. Hinzu kommt, dass die Temperatur wichtiger Rotorkomponenten nicht wirtschaftlich
messbar ist. Temperaturschätzverfahren wie modellbasierte Ansätze sind potentiell
in der Lage, das Problem der fehlenden Temperaturinformation zu relativieren,
ohne zusätzliche Geräte zu erfordern. Diese Arbeit stellt ein Portfolio von thermischen
Modellen aus dem Bereich des maschinellen Lernens zusammen. Die Untersuchung basiert
auf einem PMSM-Datensatz, der auf einem Prüfstand aufgezeichnet wurde. Neben dem
durchschnittlichen Schätzfehler diktiert die erforderliche Anzahl von Modellparametern
zahlreiche Auslegungsentscheidungen. Der gesamte Entwurfsprozess eines Modells
aus dem maschinellen Lernen wird beleuchtet und für verschiedene lineare, sowie
baumbasierte Modelle; vorschiebende, rekurrente und faltende neuronale Netze als
auch für verschiedene hybride Modellierungsansätze durchgeführt. Desweiteren wird
der hybride Modellierungsansatz über thermische neuronale Netze besonders hervorgehoben.
Sie setzen sich aus neuronalen Netzen und einem thermischen Ersatzschaltbild zusammen
und wurden erstmals vom Autor dieser Arbeit veröffentlicht. Schließlich wird ein
von Experten entworfenes, datengetriebenes thermisches Netz mit konzentrierten
Parametern über verschiedene Algorithmen optimiert und als Stand der Technik herangezogen.

text: The permanent magnet synchronous motor (PMSM) is a commonly used traction
motor in automotive applications due to its high power and torque density with
respect to volume and weight. These characteristics are constrained by the maximum
temperature at which vital components can still operate without harm. Moreover,
important rotor component temperatures cannot be measured economically. Temperature
estimation methods such as model-based approaches can alleviate the problem of
missing thermal information at potentially no additionally required equipment.
This work collates a portfolio of data-driven thermal models from the domain of
machine learning and investigates their feasibility for the task of accurate thermal
modeling on the example of a PMSM data set recorded on a test bench. Aside from
the average estimation error, the required amount of model parameters as an approximation
for the computational demand dictates design decisions throughout. The whole process
of designing a machine learning model is illuminated and carried out for varying
linear models; tree-based models; feed-forward, recurrent, and convolutional neural
networks, as well as various hybrid gray-box modeling approaches. Moreover, a
hybrid modeling paradigm with thermal neural networks is highlighted, which was
first introduced by this work's author. Eventually, an expert-designed, data-driven
lumped-parameter thermal network is optimized under different algorithms in order
to put machine learning models to the test against the state of the art of thermal
modeling.

text: On-bord DC-DC-Konverter sind das Bindeglied zwischen der Traktionsbatterie
und der Hilfsbatterie und versorgen wichtige Komponenten des Elektrofahrzeugs.
Diese Arbeit adressiert den weiten Spannungsbereich des Wandlers, der eine Folge
der variierenden Spannungen der Batterien ist. Als potentielle Topologien werden
der LLC Resonanzwandler, der aktiv geklemmte Flusswandler und der isolierte Vollbrücken-Konverter
untersucht.Zunächst wird hierbei der LLC untersucht und verschiedene Modulationstechniken
zur Abdeckung des weiten Spannungsbereichs gegenübergestellt, um zu zeigen, dass
die Frequenzverdoppler-Modulation und die alternierende Phasenverschiebungsmodulation
die maximale Temperatur der Halbleiter deutlich senken. Zum Wechsel zwischen Voll-
und Halbbrückenmodulation wird eine Modulationstechnik vorgeschlagen, welche den
transienten Magnetisierungsfluss um über 70 % respektive des konventionellen Konzept
senkt. Für den aktiv geklemmten Flusswandler wird ein verbessertes Modell vorgestellt,
das die Blockierspannung sehr genau modelliert. Zudem wird eine Snubber-Schaltung
vorgeschlagen, welche die sekundärseitige transiente Blockierspannung deutlich
reduziert. Für den isolierten Vollbrücken-Konverter werden hart- und weichschaltende
Modulationstechniken analysiert und eine hartschaltende Frequenz-Verdoppler-Modulationstechnik
vorgeschlagen, welche die maximale Schaltertemperatur deutlich reduziert und eine
Modulationstechnik mit Beschaltung vorgestellt, um zwischen dem Voll- und Halbbrückenmodus
zu wechseln. Die zuvor erarbeiteten Konverter werden unter Anwendung einer vorgestellten
Designmethodik verglichen und messtechnisch evaluiert.

text: 'On-board DC-DC converters are the connecting link between the traction battery
and the auxiliary battery and supply energy to the crucial components of an electrical
vehicle. This work addresses DC-DC converters of a wide conversion range necessary
to cover the voltage-transfer ratio resulting from the varying state of charge
of the traction and auxiliary battery and investigates three topologies for this
application: the LLC resonant converter, the active-clamp forward converter and
the isolated full-bridge converter. At first, the LLC resonant converter is analyzed
and several operating modes are investigated and proposed to better cover the
wide transfer ratio. The operating modes are benchmarked showing that the alternating-asymmetrical
phase shift modulation and the frequency-doubler modulations can significantly
reduce the MOSFET temperature. To switch from full-bridge mode to half-bridge
mode, an improved morphing modulation is proposed that reduces the flux by about
70 % compared to the conventional concept. Finally, an integrated planar transformer
is proposed to increase the power density of the LLC.The active-clamp forward
converter is investigated to propose an accurate steady-state model. A snubber
circuitry is presented to limit the voltage overshoot of the synchronous rectifier.
The isolated full-bridge converter is investigated in its hard- and soft-switching
operation. A hard-switched frequency-doubler modulation is proposed to reduce
the maximum temperature significantly. Additionally, a steady-state model is derived
to accurately calculate the current shape of the converter and a topology morphing
concept is proposed to limit the blocking voltage of the secondary-side semiconductors
during mode transition. Finally, a topology comparison and design methodology
is proposed that enables a fair topology comparison. The three aforementioned
topologies are experimentally evaluated.'

text: AbstractThe advantages of implementing demand
side management (DSM) strategies in biogas production are explored. Specifically,
the influence of agitation intervals on biogas production and the economic advantages
of DSM in fermenter agitation are examined. The model‐based study highlights the
detrimental effects of insufficient agitation, such as reduced active reaction
volume and diminished biogas yield. The article further delves into the optimal
agitation intervals corresponding to different electricity price levels and assesses
the implications of DSM on biogas production. Results substantiate that such strategies,
particularly at high and low electricity prices, can increase profit while reducing
greenhouse gas emissions.
