We conceptualized data-based decision tree construction using nine key aspects that we intended to teach, tested variations of two design elements in teaching, and analyzed the interviews qualitatively to compare student behavior to intended outcomes. We found high alignment to intentions but also deviations in data activities and informal or context-based rather than data-based reasoning. The design element of context-free (blinded) data seems to enhance data-based reasoning, while the design element of data card use showed diagnostic potential." author: - first_name: Yannik full_name: Fleischer, Yannik id: '42660' last_name: Fleischer orcid: https://orcid.org/0000-0003-0318-0329 - first_name: Rolf full_name: Biehler, Rolf id: '16274' last_name: Biehler citation: ama: Fleischer Y, Biehler R.

The method is based on establishing an\r\nequivalence between the existence of a limiting empirical zero distribution\r\n$\\mu$ and the existence of an exponential profile $g$ associated with the\r\ncoefficients of the polynomials $(P_n)_{n \\in \\mathbb{N}}$. The exponential\r\nprofile $g$, which can be roughly described by $[z^k]P_n(z) \\approx \\exp(n\r\ng(k/n))$, offers a direct route to computing the Cauchy transform $G$ of $\\mu$:\r\nthe functions $t \\mapsto tG(t)$ and $\\alpha \\mapsto \\exp(-g'(\\alpha))$ are\r\nmutual inverses. This relationship, in various forms, has previously appeared\r\nin the literature, most notably in the paper [Van Assche, Fano and Ortolani,\r\nSIAM J. Math. Anal., 1987].\r\n As a first contribution, we present a self-contained probabilistic proof of\r\nthis equivalence by representing the polynomials as generating functions of\r\nsums of independent Bernoulli random variables. This probabilistic framework\r\nnaturally lends itself to tools from large deviation theory, such as the\r\nexponential change of measure. The resulting theorems generalize and unify a\r\nrange of previously known results, which were traditionally established through\r\nanalytic or combinatorial methods.\r\n \ Secondly, using the profile-based approach, we investigate how the\r\nexponential profile and the limiting zero distribution behave under certain\r\noperations on polynomials, including finite free convolutions, Hadamard\r\nproducts, and repeated differentiation. In particular, our approach yields new\r\nproofs of the convergence results `$\\boxplus_n \\to \\boxplus$' and `$\\boxtimes_n\r\n\\to \\boxtimes$', extending them to cases where the distributions are not\r\nnecessarily compactly supported." author: - first_name: Jonas full_name: Jalowy, Jonas id: '113768' last_name: Jalowy orcid: 0000-0001-9624-2685 - first_name: Zakhar full_name: Kabluchko, Zakhar last_name: Kabluchko - first_name: Alexander full_name: Marynych, Alexander last_name: Marynych citation: ama: 'Jalowy J, Kabluchko Z, Marynych A.

Of paramount importance for the tailored mechanical properties these composite materials exhibit is the type and geometry of the fibre weave. Especially continuous fibre-reinforced thermoplastic composites are fabricated as laminates and subsequently exposed to forming processes which alter the geometry of the fibres unit cell and thus the local mechanical properties of the material. An approach utilising broadband ultrasonic waves is proposed to non-destructively determine the geometry of the unit cell of the weave.\r\n\r\nThe dispersive behaviour of woven fibre-reinforced sheets is described in accordance with the Flouquet-Bloch theorem as a phononic crystal. In order to develop a model for a description of these periodically structured waveguides, the smallest repeating unit of the wave is modelled with periodic boundary conditions. The resulting dispersion diagram exhibits similarities to that of a homogeneous plate, but additionally displays a periodicity in the wavenumber regime, which correspond with the size of the unit cell. Experimental studies of the dispersive behaviour of acoustic waves in woven fibre-reinforced samples also show a periodicity in the wavenumber regime, enabling a measurement procedure of the unit cell geometry." author: - first_name: Mareen full_name: Wippermann, Mareen id: '74624' last_name: Wippermann - first_name: Leander full_name: Claes, Leander id: '11829' last_name: Claes orcid: 0000-0002-4393-268X - first_name: Philipp full_name: Brandes, Philipp id: '70091' last_name: Brandes - first_name: Elmar full_name: Moritzer, Elmar id: '20531' last_name: Moritzer - first_name: Bernd full_name: Henning, Bernd id: '213' last_name: Henning citation: ama: 'Wippermann M, Claes L, Brandes P, Moritzer E, Henning B.

Following recent works (Faulwasser in Math Control Signals Syst 34:759–788 2022; Trélat in Math Control Signals Syst 35:685–739 2023), which generalized the classical concept of static turnpike to manifold turnpike we extend the exponential turnpike property to the exponential trim turnpike for control systems with symmetries induced by abelian or non-abelian groups. Our analysis is mainly based on the geometric reduction of control systems with symmetries. More concretely, we first reduce the control system on the quotient space and state the turnpike theorem for the reduced problem. Then we use the group properties to obtain the trim turnpike theorem for the full problem. Finally, we illustrate our results on the Kepler problem and the rigid body problem.\r\n" author: - first_name: Kathrin full_name: Flaßkamp, Kathrin last_name: Flaßkamp - first_name: Sofya full_name: Maslovskaya, Sofya id: '87909' last_name: Maslovskaya - first_name: Sina full_name: Ober-Blöbaum, Sina id: '16494' last_name: Ober-Blöbaum - first_name: Boris Edgar full_name: Wembe Moafo, Boris Edgar id: '95394' last_name: Wembe Moafo citation: ama: Flaßkamp K, Maslovskaya S, Ober-Blöbaum S, Wembe Moafo BE.

Conventionally, the input DC-link voltage is controlled to operate the LLC converter at resonance for the given operating point. However, the DC-link capacitor voltage shows a low-frequency voltage ripple (typically the second harmonic of grid frequency) in cascaded converters so that the LLC has to adapt its switching frequency within the grid period. Conventionally, the LLC converter operates 50% of the time above the resonant frequency of 40 kHz and 50% below resonance. Both operating conditions cause additional losses. However, experimental measurements indicate that the below-resonance operation causes significantly higher losses than above-resonance operation due to much higher primary and secondary transformer currents. It is better to increase the DC-link voltage by 30% of the peak-to-peak low-frequency voltage ripple to mostly avoid below-resonance operation (i.e., from 650 V to 680 V in this case). With the proposed control, the LLC converter operates about 75% of time over resonance and only 25% of time below resonance. The overall efficiency increases from 97.66% to 97.7% for the average operating point with an 80% load current. This corresponds to a 2% total loss reduction. Finally, the peak resonance capacitor voltage decreases from 910 V to 790 V (−13%). article_number: '1517' author: - first_name: Roland full_name: Unruh, Roland id: '34289' last_name: Unruh - first_name: Joachim full_name: Böcker, Joachim id: '66' last_name: Böcker orcid: 0000-0002-8480-7295 - first_name: Frank full_name: Schafmeister, Frank id: '71291' last_name: Schafmeister citation: ama: Unruh R, Böcker J, Schafmeister F.

It is a discrete-time process in which uninformed actors incrementally receive information from their informed neighbors or from the outside. Our goal is to minimize the number of confused actors — that is, the number of actors who receive contradictory information. We prove upper bounds for the number of confused actors in signed networks and in equivalence classes of signed networks. In particular, we show that there are signed networks where, for any information placement strategy, almost 60% of the actors are confused. Furthermore, this is also the case when considering the minimum number of confused actors within an equivalence class of signed graphs. author: - first_name: Ligang full_name: Jin, Ligang last_name: Jin - first_name: Eckhard full_name: Steffen, Eckhard id: '15548' last_name: Steffen orcid: 0000-0002-9808-7401 citation: ama: Jin L, Steffen E.

An important part of Iran’s censorship apparatus is its analysis of unencrypted protocols such as HTTP and DNS. During routine evaluations of Iran’s HTTP and DNS censorship, we noticed several properties we believe to be unknown today. For instance, we found injections of correct static IPs for some domains such as google.com on the DNS level, unclear HTTP version parsing, and correlations between DNS and HTTP censorship. In this paper, we present our findings to the community and discuss possible takeaways for affected people and the censorship circumvention community. As some of our findings left us bewildered, we hope to ignite a discussion about Iran’s censorship behavior. We aim to use the discussion of our work to execute a thorough analysis and explanation of Iran’s censorship behavior in the future. author: - first_name: Felix full_name: Lange, Felix id: '67893' last_name: Lange - first_name: Niklas full_name: Niere, Niklas id: '63563' last_name: Niere - first_name: Jonathan full_name: von Niessen, Jonathan last_name: von Niessen - first_name: Dennis full_name: Suermann, Dennis last_name: Suermann - first_name: Nico full_name: Heitmann, Nico id: '74619' last_name: Heitmann orcid: 0009-0003-7687-7044 - first_name: Juraj full_name: Somorovsky, Juraj id: '83504' last_name: Somorovsky orcid: 0000-0002-3593-7720 citation: ama: 'Lange F, Niere N, von Niessen J, Suermann D, Heitmann N, Somorovsky J.

Measurement results for the elastic material parameters are acquired non-destructively using ultrasonic transmission measurements of hollow cylindrical polymer specimens. To determine the material parameters, an inverse approach is used comparing measurements with simulated data. Previous studies show that the procedure exhibits low sensitivity with respect to the shear parameters of the material. In order to increase the sensitivity, we propose to apply a spatially annular excitation on the base of the specimen. As a measure to analyse the sensitivities with respect to all parameters and their linear independence, we observe the volume of the parallelotope of the sensitivity vectors. Here, a scaled boundary finite element formulation of wave propagation in the specimen is expanded to yield derivative information directly, and a sensitivity analysis can be carried out efficiently. Finally, the results of this sensitivity analysis with regard to the annular excitation are also applied to the measurement setup." article_number: '6' article_type: original author: - first_name: Dmitrij full_name: Dreiling, Dmitrij id: '32616' last_name: Dreiling - first_name: Dominik full_name: Itner, Dominik last_name: Itner - first_name: Hauke full_name: Gravenkamp, Hauke last_name: Gravenkamp - first_name: Leander full_name: Claes, Leander id: '11829' last_name: Claes orcid: 0000-0002-4393-268X - first_name: Carolin full_name: Birk, Carolin last_name: Birk - first_name: Bernd full_name: Henning, Bernd id: '213' last_name: Henning citation: ama: Dreiling D, Itner D, Gravenkamp H, Claes L, Birk C, Henning B.
