abstract = {Making and interpretation of drawings and schematics is an important skill to be developed in engineering education. The question type STACK in the Moodle learning management system combined with the interactive graphics library JSXGraph has a great potential for implementation of e-learning resources addressing these skills in formative and summative settings. The authoring process of such materials is complex due to multiple markup and programming languages like HTML, LaTeX, Maxima and JavaScript (JS) being involved. The Meclib concept mitigates this complexity and allows for efficient bulk production of material with consistent appearance and user experience. The core of Meclib is a set of pre-defined JSXGraph-based objects with an interface to Maxima, such that no problem specific JS code is required at all. The present paper outlines the basic ideas of the implementation and demonstrates the approach for some typical examples of different complexity. The focus is on applications in engineering mechanics, starting from static illustrations up to an editor for free body diagrams, with rich adaptive formative feedback.},

Ziel des vorliegenden Arbeitspapiers ist es, kleinen und mittleren Unternehmen eine Alternative zu herk{\"o}mmlichen Content Management Systemen darzulegen und sie bei der Entscheidungsfindung zu unterst{\"u}tzen. Zur Beantwortung der Forschungsfragen wurde der methodische Ansatz einer Literatur- und Internetrecherche verwendet. Aus der Analyse konnten drei Online Business Plattformen identifiziert, sowie deren Vor- und Nachteile gegen{\"u}ber Content Management Systemen dargestellt werden. Anschließend wurden Kriterien definiert und Empfehlungen dargelegt, welche kleine und mittlere Unternehmen im Entscheidungsprozess unterst{\"u}tzen sollen. Letztlich wurden die Einrichtung sowie die wichtigsten Funktionen einer Plattform dargestellt. Die Ergebnisse zeigen, dass die Nutzung einer Onlineplattform f{\"u}r lokal begrenze Unternehmen mit geringen Anforderungen an die Funktionalit{\"a}t und hoher Kostensensibilit{\"a}t eine sinnvolle Alternative ist. Abschließend wurde anhand des realen Fallbeispiels „Google My Business" (seit 2022: „Google Business Profile") auf die Funktionen sowie Vorteile und M{\"o}glichkeiten einer solchen Plattform eingegangen.},

Verschiedene Autoren haben sich an einer L{\"o}sung versucht und Herangehensweisen f{\"u}r ihre eigenen Anwendungsf{\"a}lle entwickelt. In dieser Arbeit wird ein neuer Ansatz anhand eines Fallbeispiels vorgestellt. Der An- satz zielt darauf ab, Daten- und Versionierungsstrukturen in einem relationalen Da- tenmodell zu vereinigen und dabei eine einfache Integration von Gesch{\"a}ftsprozessen zu erm{\"o}glichen. Insbesondere wird darauf geachtet, dass die Erzwingung des korrekten Ablaufs von Gesch{\"a}ftsprozessen durch eine maschinelle Umsetzung derselben m{\"o}glich ist.

Dabei steht die Zugriffskontrolle von Personen und Ger{\"a}ten im Vordergrund. Damit soll erreicht werden, dass unautorisierter Zugriff zum Netzwerk verhindert wird. Es werden die Begrifflichkeiten, Funktionsweise und potenzielle Angriffsvektoren von NAC untersucht. Des Weiteren werden die jeweiligen Funktionen der NAC-Produkte macmon und der Open-Source L{\"o}sung PacketFence gegen{\"u}bergestellt. Im praktischen Teil der Arbeit werden dann die vorgestellten Angriffsvektoren an einem Test-Netzwerk durchgef{\"u}hrt und analysiert. Die Arbeit zeigt, dass NAC eine wichtige Komponente in der Zugriffskontrolle f{\"u}r eine moderne IT-Infrastruktur ist. W{\"a}hrend einige Angriffe auf das Test-Netzwerk abgewehrt werden konnten, war es dennoch m{\"o}glich, sich als Angreifer am Netzwerk anzumelden. NAC ist ein unerl{\"a}ssliches Tool f{\"u}r gr{\"o}ßere IT-Infrastrukturen, jedoch erfordert eine korrekte Konfiguration und effektive Nutzung von NAC ein umfangreiches Wissen {\"u}ber die verschiedenen Aspekte und Themenbereiche der Netzwerksicherheit.},

The flow has been considered to be radial, incompressible and laminar. The time-dependent Navier-Stokes equation has been solved in cylindrical coordinates using Fourier transform, and the oscillating flow velocity across the thickness of the cell has been obtained at different times. The flow velocity function in the unsteady state is related to the vertical component of the coordinates in the form of parabolic functions and also to the inverse of the radial component. The time dependence appears as a simple harmonic with a frequency equal to the oscillation frequency. The velocity of the flow is maximum at the middle of the cell along its height and gradually decreases from the middle towards the top or bottom plane and reaches zero. Pressure does not depend on the height and changes logarithmically with the radius. The dependence of pressure on time is also a simple harmonic with the external frequency, but it has a phase shift with respect to the velocity.}, language = {en} } @article{LachowskiHammermeisterHalenzetal.2023, author = {Lachowski, Krzysztof and Hammermeister, Florian and Halenz, Bastian and Lieckefett, Florian and G{\"o}tze, Thomas and Prill, Robert and Becker, Roland}, title = {The Patellostabilometer: A New Device for Quantification of Mediolateral Patella Displacement}, series = {Sensors}, journal = {Sensors}, number = {23 (3)}, publisher = {MDPI}, doi = {https://doi.org/10.3390/s23031274}, year = {2023}, abstract = {Mediolateral patella displacement is of interest for diagnostics and clinically relevant research questions.

The participants underwent measurements of the mediolateral displacement three times using the Patellostabilome- ter. A maximal force of 10 N was applied for patella movement. Additionally, leg length and circumference of the knee, upper- and lower-leg were measured. Lateral patella displacement of 18.27 ± 3.76 mm (range 15.85-20.64 mm, interquartile range (IQR) of 4.79) was measured.

An alternative to the traditional top-down development of public services is co-creation of public services. Co-creation promotes collaboration between stakeholders with the aim to create better public services and achieve public values. At the same time, data analytics has been fuelled by the availability of immense amounts of textual data. Whilst both co-creation and TA have been used in the private sector, we study existing works on the application of Text Analytics (TA) techniques on text data to support public service co-creation. We systematically review 75 of the 979 papers that focus directly or indirectly on the application of TA in the context of public service development. In our review, we analyze the TA techniques, the public service they support, public value outcomes, and the co-creation phase they are used in. Our findings indicate that the TA implementation for co-creation is still in its early stages and thus still limited. Our research framework promotes the concept and stimulates the strengthening of the role of Text Analytics techniques to support public sector organisations and their use of co-creation process.

Using a discretization of the terminal density, we write these integral equations as a system of linear equations. We show that the kernel matrix of this system is, in general, ill-conditioned, so that it cannot be solved for the discretized density using a naive approach. Instead, we construct a sparse model for the kernel matrix using singular value decomposition (SVD), which allows us not only to systematically improve the condition number of the kernel matrix, but also determines the computational effort and accuracy of our method. In order to allow for the treatment of realistic inputs that may contain arbitrage, we reformulate the system of linear equations as an optimization problem, in which the SVD-transformed density minimizes the error between the input prices and the arbitrage-free prices generated by our method. To further stabilize the method in the presence of noisy input prices or arbitrage, we apply an 𝐿1-regularization to the SVD-transformed density. Our approach, which is inspired by recent progress in theoretical physics, offers a flexible and efficient framework for the arbitrage-free interpolation of plain-vanilla option prices and implied volatilities, without the need to explicitly specify a stochastic process, expansion basis functions or any other kind of model.

We analyze experimental data and compare them with a simple model where the defect clusters adiabatically pass quasi-equilibrium solutions in one-constant approximation.

A novel chromatographic sensor was developed with a deep UV LED-based photometric detection unit (255-265 nm), an original flow cuvette and registration scheme; the processing of a chromatogram with the sensor takes approximately 15 min.

One of these challenges is the growing number of photovoltaic systems (PV systems), which, due to their high feed-in power, already pose a risk to the security of the electricity distribution grid during long periods of sunny weather. To counteract this, active research is being carried out in the field of PV power forecasting. This research is primarily aimed at providing the grid operator with a predicted power output, which enables a longer planning horizon and thus increases the operational grid security. However, the considerable annual electricity consumption of private households and the increasing spread of PV systems for self-consumption show that the energy behavior of households, especially self-consumption, also influences grid security. Additionally, households have an incentive to boost their self-consumption because the cost of drawing each kilowatt-hour from the grid is substantially higher than the compensation received for injecting an equivalent amount of energy back into the grid. However, as of now, there is no software available that easily enables households to tailor the usage patterns of their electrical appliances according to a photovoltaic (PV) forecast. The project described here aims to close this gap by creating such software. Various PV forecasting models are used and tested for their suitability for this purpose. A self-generated optimization process is implemented in this project to optimize the consumer configuration based on the PV forecasts. The here-developed tool enables the user to enter parameters for his PV system and the specific load profiles of his electrical appliances. Based on this data, the optimization algorithm determines a consumption plan with a forecast horizon until the end of the next day that maximizes the user's self-consumption. To validate the tool, the optimization process is carried out over a period of 60 days using a predefined scenario and the results are compared with a scenario in which the electrical appliances are intuitively operated at midday. The analysis of these results ultimately shows the potential impact of such a tool on the economic efficiency of private households and the supply stability.}, language = {en} } @article{AyalonAvisarJechowetal.2024, author = {Ayalon, Inbal and Avisar, Dror and Jechow, Andreas and Levy, Oren}, title = {Corals nitrogen and carbon isotopic signatures alters under Artificial Light at Night (ALAN)}, series = {The Science of The Total Environment}, journal = {The Science of The Total Environment}, number = {920}, publisher = {Elsevier}, doi = {10.1016/j.scitotenv.2024.170513}, year = {2024}, abstract = {This study examines the impact of Artificial Light at Night (ALAN) on two coral species, Acropora eurystoma and Pocillopora damicornis, in the Gulf of Aqaba/Eilat Red Sea, assessing their natural isotopic responses to highlight changes in energy and nutrient sourcing due to sensory light pollution. Our findings indicate significant disturbances in photosynthetic processes in Acropora eurystoma, as evidenced by shifts in δ13C values under ALAN, pointing to alterations in carbon distribution or utilization. In Pocillopora damicornis, similar trends were observed, with changes in δ13C and δ15N values suggesting a disruption in its nitrogen cycle and feeding strategies. The study also uncovers species-specific variations in heterotrophic feeding, a crucial factor in coral resilience under environmental stress, contributing to the corals' fixed carbon budget. Light measurements across the Gulf demonstrated a gradient of light pollution which possess the potential of affecting marine biology in the region. ALAN was found to disrupt natural diurnal tentacle behaviors in both coral species, crucial for prey capture and nutrient acquisition, thereby impacting their isotopic composition and health. Echoing previous research, our study underscores the need to consider each species' ecological and physiological contexts when assessing the impacts of anthropogenic changes.

We employ them to measure the dynamics of cubes and icosahedra on vibrating plates to study the efficiency of energy transfer into the individual degrees of freedom (DOFs) of the excited object. The rotational DOFs turn out to be much less excited than the vertical translational motion.

While traditional portfolio optimization is carried out in a continuous fashion, as if stocks could be bought in fractional increments, practical implementations often resort to approximations, as fractional stocks are typically not tradeable. While these approximations are effective for large investment budgets, they deteriorate as budgets decrease. To alleviate this issue, a discrete Markowitz portfolio theory (DMPT) with finite budgets and integer stock weights can be formulated, but results in a non-polynomial (NP)-hard problem. Recent progress in quantum processing units (QPUs), including quantum annealers, makes solving DMPT problems feasible. Our study explores portfolio optimization on quantum annealers, establishing a mapping between continuous and discrete Markowitz portfolio theories. We find that correctly normalized discrete portfolios converge to continuous solutions as budgets increase. Our DMPT implementation provides efficient frontier solutions, outperforming traditional rounding methods, even for moderate budgets. Responding to the demand for environmentally and socially responsible investments, we enhance our discrete portfolio optimization with ESG (environmental, social, governance) ratings for EURO STOXX 50 index stocks. We introduce a utility function incorporating ESG ratings to balance risk, return and ESG friendliness, and discuss implications for ESG-aware investors.}, language = {en} } @article{OchkovKraskaLukatsky2024, author = {Ochkov, V.

In this Review, we elucidate the scope and importance of light pollution and discuss techniques to monitor it. In urban areas, light emissions from sources such as street lights lead to a zenith radiance 40 times larger than that of an unpolluted night sky. Non-urban areas account for over 50\% of the total night-time light observed by satellites, with contributions from sources such as transportation networks and resource extraction. Artificial light can disturb the migratory and reproductive behaviours of animals even at the low illuminances from diffuse skyglow. Additionally, lighting (indoor and outdoor) accounts for 20\% of global electricity consumption and 6\% of CO2 emissions, leading to indirect environmental impacts and a financial cost. However, existing monitoring techniques can only perform a limited number of measurements throughout the night and lack spectral and spatial resolution. Therefore, satellites with improved spectral and spatial resolution are needed to enable time series analysis of light pollution trends throughout the night.}, language = {en} } @article{VegaHoelkerZielinskaDabkowskaetal.2024, author = {Vega, Catherine Perez and H{\"o}lker, Franz and Zielinska-Dabkowska, Karolina M and Jechow, Andreas}, title = {Polarised light pollution on river water surfaces caused by artificial light at night from illuminated bridges and surroundings}, series = {Journal of Limnology}, volume = {83}, journal = {Journal of Limnology}, publisher = {PAGEPress}, doi = {10.4081/jlimnol.2024.2173}, pages = {1 -- 13}, year = {2024}, abstract = {Artificial light at night originating from bridge illumination can cause polarised light pollution when it is reflected at water body surfaces. This alters the optical conditions of a river at night and potentially interferes with natural polarisation signals from, for example, moonlight. Therefore, this type of light pollution could detrimentally change the behaviour of organisms sensitive to polarised light, a navigational cue and signal known to be used e.g. by flying water-seeking insects to detect suitable aquatic habitats to reproduce and lay eggs. So far, polarised light pollution from artificial light at night is understudied. Here, we quantify polarised light pollution at the water's surface near seven illuminated bridges crossing the river Spree in Berlin. Our measurements show for the first time, that nocturnal bridge illumination induces polarised light pollution towards potential flying paths of polarotactic aquatic insects. On average, around 9\% of the water surfaces at the investigated bridges were highly polluted by polarised light, with values ranging between 3 and 12 \% for each bridge. Thus, polarised light pollution from artificial light at night is an emergent pollutant for aquatic systems. Future work on this topic should include more comprehensive measurements, further ecological studies on its impacts and the development of sustainable lighting solutions that can contribute to the protection of riverine nightscapes.}, language = {en} } @article{Jechow2024, author = {Jechow, Andreas}, title = {Let there be Skyglow - light pollution from a large outdoor music festival (Lollapalooza Berlin 2016)}, series = {Scientific Reports}, volume = {14}, journal = {Scientific Reports}, publisher = {Springer Nature}, doi = {10.1038/s41598-024-62448-7}, pages = {1 -- 10}, year = {2024}, abstract = {Live music is often linked to elaborate light shows, particularly at large outdoor music festivals.

Here, the light pollution produced by a major rock festival (Lollapalooza Berlin 2016 with 70,000 visitors per day in an urban park) was investigated with ground-based radiometry and night-time light data. A small night-sky radiometer installed near the main stages and a calibrated digital camera from a nearby observation spot inside of the park were used to quantify changes in night sky brightness and direct light emissions within the park. The impact of the music festival on the urban skyglow was indeed measurable. Zenith luminance increased locally by up to a factor of 8 and illuminance increased by about 50\% at the observation spot within the park. The radiance detected by night-time satellite was also increased during the festival.

A peculiarity of this system is that the continuous and the discontinuous phases consist of the same material. We determine the dynamics, analyze the self-similar aging of the island size distribution and discuss characteristic exponents of the mean island growth.

Since light pollution is rarely integrated into conservation approaches, effective mitigation strategies towards environmentally friendly lighting that drastically reduce insect attraction are urgently needed. Here, we tested novel luminaires in two experiments (i) at a controlled experimental field site and (ii) on streets within three municipalities. The luminaires are individually tailored to only emit light onto the target area and to reduce spill light. In addition, a customized shielding renders the light source nearly invisible beyond the lit area. We show that these novel luminaires significantly reduce the attraction effect on flying insects compared to different conventional luminaires with the same illuminance on the ground. This underlines the huge potential of spatially optimized lighting to help to bend the curve of global insect decline without compromising human safety aspects.
