description: Die Instandhaltung von Windenergieanlagen erfolgt derzeit zumeist reaktiv und bietet damit Potenzial zur Kostensenkung und Steigerung der Anlagenverfügbarkeit. Die hierzu notwendige genaue Kenntnis der Anlagenzuverlässigkeit erfordert die detaillierte Analyse historischer Instandhaltungsberichte. Daten aus den Instandhaltungsberichten müssen hierzu strukturiert und einheitlich klassifiziert vorliegen. In der Praxis bestehen Einsatzbeschreibungen in Instandhaltungsberichte häufig aus Freitexten, existierende Standards bleiben ungenutzt und der vorhandene Datenbestand bleibt aufgrund des hohen Aufwands einer manuellen Aufbereitung unerschlossen. In dieser Arbeit wird ein Digitalisierungsworkflow skizziert, welcher bestehende I Instandhaltungsinformationen nutzbar machen soll. Hierzu werden existierende Verfahren zur Digitalisierung, Informationsextraktion und Klassifizierung vorgestellt und hinsichtlich des Einsatzes im beschriebenen Anwendungsfall bewertet. Diese Verfahren können zu einem Digitalisierungsworkflow kombiniert werden, um die für eine Instandhaltungsoptimierung notwendige Datengrundlage zu erreichen. Die hier betrachteten Verfahren stammen aus dem Bereich der Optical Character Recognition sowie des Natural Language Processing und der Textklassifikation.
K*0 and phi Meson Production in Proton-Nucleus Interactions at sqrt(s) = 41.6 GeV

description: The inclusive production cross sections of the strange vector mesons K*0, K*0bar, and phi have been measured in interactions of 920 GeV protons with C, Ti, and W targets with the HERA-B detector at the HERA storage ring. Differential cross sections as a function of rapidity and transverse momentum have been measured in the central rapidity region and for transverse momenta up to pT=3.5 GeV/c. The atomic number dependence is parametrised as sigma(pA) = sigma(pN)*A**alpha, where sigma(pN) is the proton-nucleon cross section. Within the phase space accessible, alpha(K*0) = 0.86+/-0.03, alpha(K*0bar) = 0.87+/-0.03, and alpha(phi) = 0.96+/-0.02. The total proton-nucleon cross sections, determined by extrapolating the differential measurements to full phase space, are sigma(pN->K*0) = 5.06+/-0.54 mb, sigma(pN->K*0bar) = 4.02+/-0.45 mb, and sigma(pN->phi) = 1.17+/-0.11 mb. The Cronin effect is observed for the first time for vector mesons containing strange quarks; compared to the measurements of Cronin et al. for K+- mesons, the measured values of alpha for phi mesons coincide with those of K- mesons for all transverse momenta, while the enhancement for K*0 / K*0bar mesons is smaller.

Constraining protoplanetary disks with exoplanetary dynamics: Kepler-419 as an example

description: We investigate the origins of Kepler-419, a peculiar system hosting two nearly coplanar and highly eccentric gas giants with apsidal orientations librating around anti-alignment, and use this system to place constraints on the properties of their birth protoplanetary disk. We follow the proposal by Petrovich, Wu, & Ali-Dib (2019) that these planets have been placed on these orbits as a natural result of the precessional effects of a dissipating massive disk and extend it by using direct N-body simulations and models for the evolution of the gas disks, including photoevaporation. Based on a parameter space exploration, we find that in order to reproduce the system the initial disk mass had to be at least 95 M_Jup and dissipate on a timescale of at least 10^4 yr. This mass is consistent with the upper end of the observed disk masses distribution, and the dissipation timescale is consistent with photoevaporation models. We study the properties of such disks using simplified 1D thin disk models and show that they are gravitationally stable, indicating that the two planets must have formed via core accretion and thus prone to disk migration. We hence finally investigate the sensitivity of this mechanism to the outer planet's semi major axis, and find that the nearby 7:1, 8:1, and 9:1 mean-motion resonances can completely quench this mechanism, while even higher order resonances can also significantly affect the system. Assuming the two planets avoid these high order resonances and/or close encounters, the dynamics seems to be rather insensitive to planet c semi major axis, and thus orbital migration driven by the disk.

Publisher: name: Zenodo
Year: 2023

description: This research investigates the interactive mobile learning practices of focusing on using mobile technologies, particularly Quick Response (QR) codes, to enhance listening, speaking, reading, and writing language skills. The sample comprises 280 students drawn from six higher secondary schools in Chennai district of Tamil Nadu. Interactive Mobile Learning Assessment Scale, developed and validated by the investigator, was used for collecting data.  The findings reveal that the overall mean score for interactive mobile learning practices is average; there is no significant difference in these practices among students when grouped by study group, gender, locality, and board of study. However, a significant difference is observed based on residence, indicating variations in interactive mobile learning practices between hosteller and day scholar students. The research suggests recommendations for further enhancing mobile learning practices among higher secondary students in Tamil Nadu.

description: Superoscillations are band-limited functions that can oscillate faster than their fastest Fourier component. These functions (or sequences) appear in weak values in quantum mechanics and in many fields of science and technology such as optics, signal processing and antenna theory. In this paper we introduce a new method to generate superoscillatory functions that allows us to construct explicitly a very large class of superoscillatory functions.

description: Using a Liouville measure, similar to the one proposed recently by Gibbons and Turok, we investigate the probability that single-field inflation with a polynomial potential can last long enough to solve the shortcomings of the standard hot big bang model, within the semiclassical regime of loop quantum cosmology. We conclude that, for such a class of inflationary models and for natural values of the loop quantum cosmology parameters, a successful inflationary scenario is highly improbable.

description: We apply a recently suggested technique of the Neumann-Dirichlet reduction to a toy model of brane-induced gravity for the calculation of its quantum one-loop effective action. This model is represented by a massive scalar field in the $(d+1)$-dimensional flat bulk supplied with the $d$-dimensional kinetic term localized on a flat brane and mimicking the brane Einstein term of the Dvali-Gabadadze-Porrati (DGP) model. We obtain the inverse mass expansion of the effective action and its ultraviolet divergences which turn out to be non-vanishing for both even and odd spacetime dimensionality $d$. For the massless case, which corresponds to a limit of the toy DGP model, we obtain the Coleman-Weinberg type effective potential of the system. We also obtain the proper time expansion of the heat kernel in this model associated with the generalized Neumann boundary conditions containing second order tangential derivatives. We show that in addition to the usual integer and half-integer powers of the proper time this expansion exhibits, depending on the dimension $d$, either logarithmic terms or powers multiple of one quarter. This property is considered in the context of strong ellipticity of the boundary value problem, which can be violated when the Euclidean action of the theory is not positive definite.

description: We argue that the superpartner of the Dirac right-handed neutrino is a prime candidate for dark matter created from a 'mattergenesis' mechanism. We show that due to the smallness of the Yukawa couplings, a right-handed sneutrino density created in the early Universe would not be erased by annihilations, which remain out of thermal equilibrium. It would also not be drowned by a later, additional production of right-handed sneutrinos, as the relic density of the non-thermal right-handed sneutrinos is found to be generally negligible compared to the observed dark matter density. Mild constraints on sneutrino masses and trilinear SUSY-breaking couplings are obtained. Possible mattergenesis scenarios are also mentioned

description: It has been recently suggested that optical interferometers may not require a phase-stable optical link between the stations if instead sources of quantum-mechanically entangled pairs could be provided to them, enabling extra-long baselines and benefiting numerous topics in astrophysics and cosmology. We developed a new variation of this idea, proposing that photons from two different sources could be interfered at two decoupled stations, requiring only a slow classical connection between them. We show that this approach could allow high-precision measurements of the relative astrometry of the two sources, with a simple estimate giving angular resolution of $10 \ μ$as in a few hours' observation of two bright stars. We also give requirements on the instrument for these observations, in particular on its temporal and spectral resolution. Finally, we discuss possible technologies for the instrument implementation and first proof-of-principle experiments.

description: Computer games can support university teaching by promoting strategic, planning, and networked thinking. Especially in supply chain management, many processes require coordination, effects of actions need to be predicted, and decisions are made under time pressure. A structured and analytical approach is therefore of great importance, which is particularly promoted by playing computer games. We demonstrate the use of Rise of Industry to deepen students’ understanding of supply chain management, covering logistics and production control as well as interactions and interdependencies between the components of supply chains. Using Constructive Alignment, we define intended learning outcomes and activities of a computer game-based learning course and derive requirements for selecting and adapting a computer game. Evaluating a three-day seminar, we find that students were able to apply prior knowledge to the game world and improve their decision making while experiencing the immediate economic and ecological impacts of their actions through the game.

description: The textile industry has a detrimental impact on the environment and faces challenges to meet climate and environmental goals. The core problem is its linear system where only a small fraction of used garments is reused or recycled. To facilitate recycling of textiles, a sorting method is proposed that provides the necessary information about a garment to sort it into the appropriate recycling channel. Current methods have difficulties identifying garments polluted by chemicals used during dyeing and finishing which hinder recycling into new high-quality fibers. In this concept paper, the Circular Textile Intelligence (CRTX) project is outlined which addresses the central problem of linear structures in the textile industry. A spectroscopy and AI-based method for textile sorting will enable more informed decisions about optimal reuse and recycling channels, thus closing the loop. It will build upon a material database containing information about materials, textiles, dyes, finishings, and unwanted hazardous substances.

description: We examine the potential of the future medium-baseline reactor neutrino oscillation (MBRO) experiments in studying neutrino wave-packet impact. In our study, we treat neutrinos as wave packets and use the corresponding neutrino flavor transition probabilities. The delocalization, separation and spreading of the wave packets lead to decoherence and dispersion effects, which modify the plane-wave neutrino oscillation pattern, by amounts that depend on the energy uncertainties in the initial neutrino wave packets. We find that MBRO experiments could be sensitive to the wave-packet impact, since the baseline is long enough and also the capability of observing small corrections to the neutrino oscillations due to excellent detector energy resolution. Besides studying the constraints on the decoherence parameter, we also examine the potential wave-packet impacts on the precision of measuring $θ_{12}$ and other oscillation parameters in the future medium-baseline reactor neutrino oscillation experiments. Moreover, we also probe the potential benefits of an additional detector for studying such exotic neutrino physics.

Bordemann proved this existence using the framework of Thomas-Whitehead connections. In [9], we gave a new proof of the same theorem thanks to the Cartan connections. After these works there was no explicit formula for the quantization. In this paper, we give this formula using the formula in terms of Cartan connections given in [9]. This explicit formula constitutes the generalization to any order of the formulae at second and third orders soon published by Bouarroudj in [2] and [3].

description: Due to the vast increase and versatility of Additive Manufacturing and 3D-printing, in this study, the mechanical behavior of implementing both continuous and short carbon fiber within Nylon and investigated for its effectiveness within additively manufactured prints. Here, 0.1wt% of pure nylon was combined with carbon nanotubes through both dry and heat mixing to determine the best method and used to create printable filaments. Compression, tensile and short beam shear (SBS) samples were created and tested to determine maximum deformation and were simulated using ANSYS and its ACP Pre tool. SEM imaging was used to analyze CNT integration within the nylon filament, as well as the fractography of tested samples. Experimental testing shows that compressive strength increased by 28%, and the average SBS samples increased by 8% with minimal impacts on the tensile strength. The simulated results for Nylon/CF tensile samples were compared to experimental results and showed that lower amounts of carbon fiber samples tend to have lower errors.

description: We present observations from the Transiting Exoplanet Survey Satellite (TESS) of twenty bright core-collapse supernovae with peak TESS-band magnitudes $\lesssim18$ mag. We reduce this data with an implementation of the image subtraction pipeline used by the All-Sky Automated Survey for Supernovae (ASAS-SN) optimized for use with the TESS images. In empirical fits to the rising light curves, we do not find strong correlations between the fit parameters and the peak luminosity. Existing semi-analytic models fit the light curves of the Type II supernovae well, but do not yield reasonable estimates of the progenitor radius or explosion energy, likely because they are derived for use with ultraviolet observations while TESS observes in the near-infrared. If we instead fit the data with numerically simulated light curves, the rising light curves of the Type~II SNe are consistent with the explosions of red supergiants. While we do not identify shock breakout emission for any individual event, when we combine the fit residuals of the Type II supernovae in our sample, we do find a $>5σ$ flux excess in the $\sim 0.5$~day before the start of the light curve rise. It is likely that this excess is due to shock breakout emission, and that during its extended mission TESS will observe a Type II supernova bright enough for this signal to be detected directly.

The results are compared with a recently proposed extension of the asymptotic formula of Luscher. We find that contributions, which were neglected in the latter, are numerically very small at the two-loop level and conclude that for Mpi*L>2, L>2fm the finite volume effects in the meson sector are analytically well under control.

description: For infinite (bulk) quantum fluids of particles interacting via pairwise sufficiently smooth interactions, the Wigner-Kirkwood formalism provides a semiclassical expansion of the Boltzmann density in configuration space in even powers of the thermal de Broglie wavelength $λ$. This result permits one to generate an analogous $λ$-expansion for the bulk free energy and many-body densities. The present paper brings a technically nontrivial generalization of the Wigner-Kirkwood technique to semi-infinite quantum fluids, constrained by a plane hard wall impenetrable to particles. In contrast to the bulk case, the resulting Boltzmann density involves also position-dependent terms of type $\exp(-2x^2/λ^2)$ ($x$ denotes the distance from the wall boundary) which are non-analytic in $λ$. Under some condition, the analyticity in $λ$ is restored by integrating the Boltzmann density over configuration space; however, in contrast to the bulk free energy, the semiclassical expansion of the surface part of the free energy (surface tension) contains odd powers of $λ$, too. Explicit expressions for the leading quantum corrections in the presence of the boundary are given for the one-body and two-body densities. As model systems for explicit calculations, we use Coulomb fluids, in particular the one-component plasma defined in the $ν$-dimensional (integer $ν\ge 2$) space.

description: The report presents the main findings of the iPRODUCE Task2.1 survey, aiming to capture insights about makerspaces’ acceptance, main drivers, and barriers. The survey was conducted in the project’s 6 CMDFs pilot countries, capturing main outcomes regarding general EU citizens’, makers’ and manufacturers’ perceptions, needs and potential differences. The report is structured as follows: Section 1 provides a short description of the context that motivated the project and introduces the main research questions that guided this study. Section 2 presents a literature review regarding the main drivers, barriers, and challenges of makerspaces, in order to present the current state-of-the-art in the field of social manufacturing. Section 3 includes all information related to the survey design and the implementation. In Section 4, we present some initial descriptive findings closely related to individual perceptions and levels of acceptance and highlight any significant variations between different EU areas. This section also includes the main statistical analysis of the dataset by including the outcomes of the factor analysis and logit model that we have built. Section 5 provides some theoretical recommendations, based on the identified behavioural and intentional insights that were captured in T2.1, highlighting potentially desirable features with regard to the design of the iPRODUCE platform for social manufacturing. Summary of key findings, conclusions and further discussion are presented in Section 6.

description: Ride-sharing nowadays is a term most people have heard about. It is an efficient way to reduce both climate detrimental emissions and the overall traffic within large cities. A key aspect of ride-sharing is to match drivers and passengers according to a set of attributes. By matching people based on static and dynamic settings such as social preferences, this paper shows a fast and efficient approach for solving this problem. As a key difference to other solutions the core of the developed instant matching algorithm is built up on isochrones. These are used to match trips on specific geographical constraints, like the maximum detour and time until a passenger’s pickup. Furthermore, social metrics allow optimization based on individual preferences in the users trip selection. The
The Efficacy of Event Isotropy as an Event Shape Observable

description: Event isotropy $\mathcal{I}^\text{sph}$, an event shape observable that measures the distance of a final state from a spherically symmetric state, is designed for new physics signals that are far from QCD-like. Using a new technique for producing a wide variety of signals that can range from near-spherical to jetty, we compare event isotropy to other observables. We show that thrust $T$ and the $C$ parameter (and $λ_\text{max}$, the largest eigenvalue of the sphericity matrix) are strongly correlated and thus redundant, to a good approximation. By contrast, event isotropy adds considerable information, often serving to break degeneracies between signals that would have almost identical $T$ and $C$ distributions. Signals with broad distributions in $T$ (or $λ_\text{max}$) and in $\mathcal{I}^\text{sph}$ separately often have much narrower distributions, and are more easily distinguished, in the $({\mathcal{I}^\text{sph}},λ_\text{max})$ plane. An intuitive, semi-analytic estimation technique clarifies why this is the case and assists with the interpretation of the distributions.

Magnitude is determined from a combination of field surveys of deposits and empirical methods, and calculations of probable magnitudes reconstructed from field evidence of peak discharge. Typical magnitudes are determined for basins in which sediment supply and debris transport limit the range of possible debris flow magnitudes. Sediment storage in channels is quantified by using an erodibility index in order to quantify the largest expected magnitude. Although this index requires refinement, it points to the sediment distribution pattern along channels, and in some cases allows extrapolation to unsurveyed channel reaches. Debris flow basins are classified into weathering-limited and transport-limited types according to their debris availability. This classification proves useful when estimates of total event volume are made from peak discharge evidence, and significantly improves the explained variance in the prediction of both frequency and magnitude. Discriminant functions are then developed to formalize the a priori identification of basin type. A sample of 12 basins is used to test the discriminant functions. All test basins were correctly classified which highlights the usefulness and regional applicability of this approach. Morphometric and geotechnical variables were measured on debris flow basins and subjected to regression analysis to identify the most important variables in accounting for the observed debris flow activity. Validation by an independent data set has shown some promising results. However, the overall performance of the regression model indicates the difficulties in reliably estimating debris flow activity. Large deviations between the predicted and observed values probably reflect the insufficient quality of the test data set. The study emphasizes that simple univariate and bivariate models can be used to draw geotechnical envelopes for debris flow activity, but lack higher predictive power. Prediction can be significantly improved by classifying basins as transport- and weathering limited prior to the regression analysis. Both model establishment and model testing require higher quality data than are presently available, which raises the need for more regular monitoring of debris flow channels Longer records of debris flow frequency and magnitude will benefit geomorphologists in understanding the tempo of geomorphic change, and will aid engineers concerned with the appropriate management of sites and structures threatened by debris flow.

description: We report the first observation of a transient relativistic jet from the canonical black hole candidate, Cygnus X-1, obtained with the Multi-Element Radio-Linked Interferometer Network (MERLIN). The jet was observed in only one of six epochs of MERLIN imaging of the source during a phase of repeated X-ray spectral transitions in 2004 Jan--Feb, and this epoch corresponded to the softest 1.5-12 keV X-ray spectrum. With only a single epoch revealing the jet, we cannot formally constrain its velocity. Nevertheless, several lines of reasoning suggest that the jet was probably launched 0.5-4.0 days before this brightening, corresponding to projected velocities of 0.2c < v_app < 1.6c, and an intrinsic velocity of > 0.3c. We also report the occurrence of a major radio flare from Cyg X-1, reaching a flux density of ~120 mJy at 15 GHz, and yet not associated with any resolvable radio emission, despite a concerted effort with MERLIN. We discuss the resolved jet in terms of the recently proposed 'unified model' for the disc-jet coupling in black hole X-ray binaries, and tentatively identify the 'jet line' for Cyg X-1. The source is consistent with the model in the sense that a steady jet appears to persist initially when the X-ray spectrum starts softening, and that once the spectral softening is complete the core radio emission is suppressed and transient ejecta / shock observed. However, there are some anomalies, and Cyg X-1 clearly does not behave like a normal black hole transient in progressing to the canonical soft / thermal state once the ejection event has happened.

Many ways to stay in the game: Individual variability maintains high biodiversity in planktonic micro-organisms

description: In apparent contradiction to competition theory, the number of known, co-existing plankton species far exceeds their explicable biodiversity - a discrepancy termed the Paradox of the Plankton. We introduce a new game-theoretic model for competing micro-organisms in which one player consists of all organisms of one species. The stable points for the population dynamics in our model, known as strategic behavior distributions (SBDs), are probability distributions of behaviors across all organisms which imply a stable population of the species as a whole. We find that intra-specific variability is the key characteristic that ultimately allows co-existence because the outcomes of competitions between individuals with variable competitive abilities is unpredictable. Our simulations based on the theoretical model show that up to 100 species can coexist for at least 10000 generations, and that even small population sizes or species with inferior competitive ability can survive when there is intra-specific variability. In nature, this variability can be observed as niche differentiation, variability in environmental and ecological factors, and variability of individual behaviors or physiology. Therefore previous specific explanations of the paradox are consistent with and provide specific examples of our suggestion that individual variability is the mechanism which solves the paradox.

description: Developing, scaling, and deploying modern Machine Learning solutions remains challenging for small- and middle-sized enterprises (SMEs). This is due to a high entry barrier of building and maintaining a dedicated IT team as well as the difficulties of real-world data (RWD) compared to standard benchmark data. To address this challenge, we discuss the implementation and concepts of Chameleon, a semi-AutoML framework. The goal of Chameleon is fast and scalable development and deployment of production-ready machine learning systems into the workflow of SMEs. We first discuss the RWD challenges faced by SMEs. After, we outline the central part of the framework which is a model and loss-function zoo with RWD-relevant defaults. Subsequently, we present how one can use a templatable framework in order to automate the experiment iteration cycle, as well as close the gap between development and deployment. Finally, we touch on our testing framework component allowing us to investigate common model failure modes and support best practices of model deployment governance.

description: We reformulate recent insights into black hole information in a manner emphasizing operationally-defined notions of entropy, Lorentz-signature descriptions, and asymptotically flat spacetimes. With the help of replica wormholes, we find that experiments of asymptotic observers are consistent with black holes as unitary quantum systems, with density of states given by the Bekenstein-Hawking formula. However, this comes at the cost of superselection sectors associated with the state of baby universes. Spacetimes studied by Polchinski and Strominger in 1994 provide a simple illustration of the associated concepts and techniques, and we argue them to be a natural late-time extrapolation of replica wormholes. The work aims to be self-contained and, in particular, to be accessible to readers who have not yet mastered earlier formulations of the ideas above.

description: In manufacturing, small and medium-sized enterprises (SMEs) face global competition. In the field of predictive maintenance (PdM), artificial intelligence (AI) helps to prevent machine failures and has the potential to significantly reduce costs and increase process efficiency. Even though PdM has several benefits, it also entails considerable challenges for SMEs, especially when it comes to user interactions. In this short paper, we harness the design science methodology and discuss several problems regarding user interactions with predictive maintenance applications. We incorporate two different literature streams, namely, predictive maintenance and decision support systems. Finally, we present necessary design requirements, principles, features, and propose a research design to further develop and evaluate a user-centric PdM decision support system. Thereby, we contribute to making AI tangible in SMEs.

description: In an experiment performed at the SPIRAL1 facility of GANIL, the beta decay of 32Ar has been studied by means of the "Silicon Cube" device associated with germanium clover detectors from the EXOGAM array. Beta-delayed protons and gamma rays have been observed and allowed the determination of all relevant decay branches. The Gamow-Teller strength distribution is compared to shell-model calculations and excellent agreement is found. The Fermi strength is inline with expectations. A quasi-complete decay scheme of 32Ar is established.
