text: We investigate the demographic characteristics, trading patterns, and performance
of 465.926 brokerage accounts with respect to cryptocurrency trading. We find
that cryptocurrency trading became increasingly popular across individuals of
all different groups of age, gender, and trading patterns. Yet, men are more likely
to engage in cryptocurrency trading, trade more frequently, and more speculative,
respectively. As a result, men realize lower returns. Furthermore, we find that
investors vary their trading patterns across different asset classes.

text: Existing tools for automated machine learning, such as Auto-WEKA, TPOT, auto-sklearn,
and more recently ML-Plan, have shown impressive results for the tasks of single-label
classification and regression. Yet, there is only little work on other types of
machine learning problems so far. In particular, there is almost no work on automating
the engineering of machine learning solutions for multi-label classification (MLC).
We show how the scope of ML-Plan, an AutoML-tool for multi-class classification,
can be extended towards MLC using MEKA, which is a multi-label extension of the
well-known Java library WEKA. The resulting approach recursively refines MEKA's
multi-label classifiers, nesting other multi-label classifiers for meta algorithms
and single-label classifiers provided by WEKA as base learners. In our evaluation,
we find that the proposed approach yields strong results and performs significantly
better than a set of baselines we compare with.

text: Gummi-Metall-Teile (GM-Teile) werden zur Schwingungsreduktion u. a. in Windenergieanlagen
eingesetzt. Mögliche Anwendungen der Teile liegen in Wellen-, Generator- und Getriebelagerungen,
Lagern für die Gondel und ihre Komponenten sowie in Drehmomentstützen. Mit dem
Ziel eine prädiktive Instandhaltung zu realisieren, soll eine Zustandsüberwachung
für die GM-Teile entwickelt werden. Diese Entwicklung basiert auf der Umsetzung
diverser Schritte. Neben der funktionalen Betrachtung wird zwingend auch die konstruktive
Integration der Sensoren in das überwachte Teil berücksichtigt. Der Schwerpunkt
dieser Arbeit liegt auf der verwendeten Messgröße Temperatur, die mittels ausgewählter
Sensorik detektiert wird. Dabei werden Lebensdauerversuche unter instationären
Betriebsbedingungen durchgeführt, um diese Messdaten zu generieren. In der Datenauswertung
werden sie hinsichtlich der Degradierung des GM-Teils analysiert und für die Ermittlung
der nutzbaren Restlebensdauer verwendet. Rubber-metal-elements are used for isolation
of vibrations e. g. in wind turbines. Possible applications of the elements are
shaft bearings, generator bearings, gearbox bearings, bearings for the nacelle
and its components and torque supports. In order to realize predictive maintenance,
an accurate condition monitoring system for rubber-metal-elements should be developed.
During that development different aspects have to be implemented. Additionally
to the functional analysis, the constructive integration of the sensors into the
monitored part is mandatory. The focus of this work is on the measured variable
temperature, which is detected by means of appropriate sensors. Thereby lifetime
tests are run under non-stationary operating conditions to generate temperature
measurements. During data analysis, the measured data is analyzed regarding the
degradation of the rubber-metal-elements and remaining useful lifetimes are estimated.

text: In der Entwicklung mechatronischer Systeme spielt die Steigerung der Verlässlichkeit
und somit auch der Zuverlässigkeit und der funktionalen Sicherheit eine entscheidende
Rolle. Die modellbasierte Entwicklung liefert in Kombination mit unterstützender
Software einen wichtigen Beitrag zur Absicherung der Verlässlichkeit mechatronischer
Systeme in frühen Entwicklungsphasen. In der Nutzungsphase ermöglichen aktuelle
Verfahren der Zustandsüberwachung und moderne Methoden der Regelungstechnik eine
effektive Absicherung. Modelle aus der Entwicklung mechatronischer Systeme enthalten
weitreichende Informationen über die Architektur, das Verhalten und die Verlässlichkeit
eines Systems. Diese Modelle können als Grundlage für die Erstellung eines Digitalen
Zwillings für die vorausschauende Instandhaltung verwendet und mit Zustandsdaten
des realen Systems kombiniert werden. Die Nutzung der Modelle für den Digitalen
Zwilling bietet weitreichende Potenziale und vereinfacht dessen Erzeugung. Die
Veröffentlichung beschreibt Rahmenbedingungen der Integration und stellt die Potenziale
des Digitalen Zwillings zur vorausschauenden Instandhaltung dar.

text: Für die Zerstäubung hochviskoser Flüssigkeiten werden neben Düsenzerstäubern
vor allem UltraschallStehwellenzerstäuber angewendet [1]. Diese ermöglichen ohne
weitere Maßnahmen zwar keine gerichtete Zerstäubung, benötigen jedoch im Gegensatz
zu Düsenzerstäubern keine hohen Drücke und haben keine hohen Austrittsgeschwindigkeiten.
Zur Erzeugung der Ultraschallwellen werden typischerweise piezoelektrische, mit
Bolzen verschraubte LangevinWandler verwendet [1-4], die eine starke Schallabstrahlung
bei einer elektrischen Eingangsleistung von bis zu einigen Kilowatt erzeugen können.
Wie bei jedem anderen schwingenden System emittiert der Ultraschallwandler zunächst
eine Wanderwelle. Mit einem Reflektor, der gegenüber der Sonotrode angeordnet
ist, wird eine stehende Welle erzeugt. Im Resonanzabstand zwischen Reflektor und
Wandler werden abgestrahlte und reflektierte Wellen so überlagert, dass höhere
Schalldruckamplituden erzielt werden. Ein einfacher Ansatz zur Maximierung des
Schallpegels im Stehwellenfeld ist die Erhöhung der Schwingungsamplituden des
Wandlers, die jedoch zu Schäden oder zumindest zu einer Verringerung der Lebensdauer
führen kann. Hohe Schalldrücke werden auch bei geringen Abständen zwischen Wandler
und Reflektor erreicht. Das Volumen des Schallfeldes ist in diesem Fall jedoch
für die meisten Prozesse zu klein. Ein weiterer Ansatz ist die Verwendung zweier
entgegengesetzt angeordneter Wandler [5]. In diesem Fall erfordert jedoch die
Erzeugung einer stehenden Welle eine genaue Abstimmung von Frequenz und Phase
beider Wandler, was eine komplexe Steuerung erfordert. Ebenso ist es möglich,
geometrische Randbedingungen des Stehwellensystems zu optimieren, sodass es zu
optimaler Interferenz der Wellen kommt. Im Folgenden wird der Anschaulichkeit
halber vereinfachend angenommen, dass der Wandler an seiner Sonotrodenoberfläche
einzelne Schallstrahlen aussendet, die in Nähe des Wandlers nahezu parallel verlaufen
und sich mit zunehmender Entfernung vom Wandler auffächern. Ein einfaches Stehwellensystem,
bestehend aus ebener Sonotrode und ebenem Reflektor, erzeugt bei kleinem Abstand
zwischen Sonotrode und Reflektor sehr hohe Schallpegel, da nahezu sämtliche ausgesandten
Schallstrahlen in Richtung der Sonotrode reflektiert werden positive Interferenz
entsteht. Erhöht man jedoch den Abstand zwischen Sonotrode und Reflektor, so nehmen
die Verluste durch Schallstrahlen, die den Prozessraum verlassen, zu. Wie Abbildung
1 gezeigt, werden nur Schallstrahlen, die in etwa parallel zur Rotationsachse
verlaufen, zum Wandler zurück reflektiert und tragen zum Stehwellenfeld bei. Die
Strahlen haben zudem abhängig vom Abstrahlwinkel unterschiedliche Weglängen. Die
Stehwellenbedingung ist demnach nur für Strahlen in der Nähe der Rotationsachse
exakt erfüllt. Um dies zu vermeiden, müssen die Geometrien von Wandler und Reflektor
optimiert werden. In den folgenden Abschnitten wird zunächst ein Optimierungsansatz
vorgestellt. Mithilfe eines FiniteElemente-Modells werden die Auswirkungen einer
optimierten Geometrie auf den maximalen Schalldruckpegel untersucht. Ergebnisse
werden durch Messungen an einem experimentellen Aufbau eines Stehwellensystems
validiert. Es wird gezeigt, wie sich die Optimierung der geometrischen Randbedingungen
auf die Zerstäubung hochviskoser Flüssigkeiten auswirkt.

text: 'Are cryptocurrency traders driven by a desire to invest in a new asset class
to diversify their portfolio or are they merely seeking to increase their levels
of risk? To answer this question, we use individual-level brokerage data and study
their behavior in stock trading around the time they engage in their first cryptocurrency
trade. We find that when engaging in cryptocurrency trading investors simultaneously
increase their risk-seeking behavior in stock trading as they increase their trading
intensity and use of leverage. The increase in risk-seeking in stocks is particularly
pronounced when volatility in cryptocurrency returns is low, suggesting that their
overall behavior is driven by excitement-seeking. '

text: 'Competing firms tend to select similar locations for their stores. This phenomenon,
called the principle of minimum differentiation, was captured by Hotelling with
a landmark model of spatial competition but is still the object of an ongoing
scientific debate. Although consistently observed in practice, many more realistic
variants of Hotelling''s model fail to support minimum differentiation or do not
have pure equilibria at all. In particular, it was recently proven for a generalized
model which incorporates negative network externalities and which contains Hotelling''s
model and classical selfish load balancing as special cases, that the unique equilibria
do not adhere to minimum differentiation. Furthermore, it was shown that for a
significant parameter range pure equilibria do not exist. We derive a sharp contrast
to these previous results by investigating Hotelling''s model with negative network
externalities from an entirely new angle: approximate pure subgame perfect equilibria.
This approach allows us to prove analytically and via agent-based simulations
that approximate equilibria having good approximation guarantees and that adhere
to minimum differentiation exist for the full parameter range of the model. Moreover,
we show that the obtained approximate equilibria have high social welfare.'

text: We study text reuse related to Wikipedia at scale by compiling the first corpus
of text reuse cases within Wikipedia as well as without (i.e., reuse of Wikipedia
text in a sample of the Common Crawl). To discover reuse beyond verbatim copy
and paste, we employ state-of-the-art text reuse detection technology, scaling
it for the first time to process the entire Wikipedia as part of a distributed
retrieval pipeline. We further report on a pilot analysis of the 100 million reuse
cases inside, and the 1.6 million reuse cases outside Wikipedia that we discovered.
Text reuse inside Wikipedia gives rise to new tasks such as article template induction,
fixing quality flaws, or complementing Wikipedia's ontology. Text reuse outside
Wikipedia yields a tangible metric for the emerging field of quantifying Wikipedia's
influence on the web. To foster future research into these tasks, and for reproducibility's
sake, the Wikipedia text reuse corpus and the retrieval pipeline are made freely
available.
