Publisher: name: Gesellschaft für Didaktik der Mathematik
Year: 2015
Subjects: subject: 510

description: Mit diesem Beitrag sollen einige Ergebnisse einer Interviewstudie präsentiert werden. Ausgehend von den international vielfach diskutierten Early- Algebra-Ansätzen, die eine Verbindung und gegenseitige Stützung arithmetischer und algebraischer Inhalte im Mathematikunterricht anstreben, geht es um die Erkundung algebraischer Fähigkeiten von Schülerinnen und Schülern im Grundschulalter (Fritzlar & Karpinski-Siebold, 2012). Konkret sollten folgende zwei Forschungsfragen Beantwortung finden: - Wie kann algebraisches Denken im Grundschulalter beschrieben werden? - Welche entsprechenden Fähigkeiten bezüglich des algebraischen Denkens sind im 4. Schuljahr ohne vorherige spezifische Programme zu erfassen?

description: Graviton propagator diverges in certain gauges in de Sitter spacetime. We address this problem in this work by generalizing the infinitesimal BRST transformations in de Sitter spacetime to finite field-dependent BRST (FFBRST) transformations. These FFBRST transformations are symmetry of the classical action, but do not leave path integral measure invariant for the graviton theory in de Sitter spacetime. Due to the non-trivial Jacobian of such finite transformation the path integral measure changes and hence FFBRST transformation is capable of relating theories in two different gauges. We explicitly construct FFBRST transformation which relates theory with diverging graviton two-point function to theory with infrared (IR) finite graviton. The FFBRST transformation thus establishes that divergence in graviton two-point function may be only a gauge artifact.

description: Transition disks correspond to a short stage between the young protoplanetary phase and older debris phase. Along this evolutionary sequence, the gas component disappears leaving room for a dust-dominated environment where already-formed planets signpost their gravitational perturbations. We endeavor to study the very inner region of the well-known and complex debris, but still gas-rich disk, around HD 141569A using the exquisite high-contrast capability of SPHERE at the VLT. Recent near-infrared (IR) images suggest a relatively depleted cavity within ~200 au, while former mid-IR data indicate the presence of dust at separations shorter than ~100 au. We obtained multi-wavelength images in the near-IR in J, H2, H3 and Ks bands with the IRDIS camera and a 0.95-1.35 micrometers spectral data cube with the IFS. Data were acquired in pupil-tracking mode, thus allowing for angular differential imaging. We discovered several new structures inside 1", of which the most prominent is a bright ring with sharp edges (semi-major axis: 0.4") featuring a strong north-south brightness asymmetry. Other faint structures are also detected from 0.4" to 1" in the form of concentric ringlets and at least one spiral arm. Finally, the VISIR data at 8.6 micrometers suggests the presence of an additional dust population closer in. Besides, we do not detect companions more massive than 1-3 mass of Jupiter. The performance of SPHERE allows us to resolve the extended dust component, which was previously detected at thermal and visible wavelengths, into very complex patterns with strong asymmetries ; the nature of these asymmetries remains to be understood. Scenarios involving shepherding by planets or dust-gas interactions will have to be tested against these observations.

description: The Covid-19 pandemic has changed the way humans interact with their environment. Common touch surfaces such as elevator switches and ATM switches are hazardous to touch as they are used by countless people every day, increasing the chance of getting infected. So, a need for touch-less interaction with machines arises. In this paper, we propose a method of recognizing the ten decimal digits (0-9) by writing the digits in the air near a sensing printed circuit board using a human hand. We captured the movement of the hand by a sensor based on projective capacitance and classified it into digits using an Artificial Neural Network. Our method does not use pictures, which significantly reduces the computational requirements and preserves users' privacy. Thus, the proposed method can be easily implemented in public places.

description: A harvest-use-store power splitting (PS) relaying strategy with distributed beamforming is proposed for wirelesspowered multi-relay cooperative networks in this paper. Different from the conventional battery-free PS relaying strategy, harvested energy is prioritized to power information relaying while the remainder is accumulated and stored for future usage with the help of a battery in the proposed strategy, which supports an efficient utilization of harvested energy. However, PS affects throughput at subsequent time slots due to the battery operations including the charging and discharging. To this end, PS and battery operations are coupled with distributed beamforming. A throughput optimization problem to incorporate these coupled operations is formulated though it is intractable. To address the intractability of the optimization,a layered optimization method is proposed to achieve the optimal joint PS and battery operation design with non-causal channel state information (CSI), in which the PS and the battery operation can be analyzed in a decomposed manner. Then, a general case with causal CSI is considered, where the proposed layered optimization method is extended by utilizing the statistical properties of CSI. To reach a better tradeoff between performance and complexity, a greedy method that requires no information about subsequent time slots is proposed. Simulation results reveal the upper and lower bound on performance of the proposed strategy, which are reached by the layered optimization method with non-causal CSI and the greedy method, respectively. Moreover, the proposed strategy outperforms the conventional PS-based relaying without energy accumulation and time switching-based relaying strategy.

description: Origin-Destination Matrix (ODM) estimation is a classical problem in transport engineering aiming to recover flows from every Origin to every Destination from measured traffic counts and a priori model information. In addition to traffic counts, the present contribution takes advantage of probe trajectories, whose capture is made possible by new measurement technologies. It extends the concept of ODM to that of Link dependent ODM (LODM), keeping the information about the flow distribution on links and containing inherently the ODM assignment. Further, an original formulation of LODM estimation, from traffic counts and probe trajectories is presented as an optimisation problem, where the functional to be minimized consists of five convex functions, each modelling a constraint or property of the transport problem: consistency with traffic counts, consistency with sampled probe trajectories, consistency with traffic conservation (Kirchhoff's law), similarity of flows having close origins and destinations, positivity of traffic flows. A primal-dual algorithm is devised to minimize the designed functional, as the corresponding objective functions are not necessarily differentiable. A case study, on a simulated network and traffic, validates the feasibility of the procedure and details its benefits for the estimation of an LODM matching real-network constraints and observations.

description: The spectra of turbulent heat flux $\mathrm{H}(k)$ in Rayleigh-Bénard convection with and without uniform rotation are presented. The spectrum $\mathrm{H}(k)$ scales with wave number $k$ as $\sim k^{-2}$. The scaling exponent is almost independent of the Taylor number $\mathrm{Ta}$ and Prandtl number $\mathrm{Pr}$ for higher values of the reduced Rayleigh number $r$ ($ > 10^3$). The exponent, however, depends on $\mathrm{Ta}$ and $\mathrm{Pr}$ for smaller values of $r$ ($<10^3$). The probability distribution functions of the local heat fluxes are non-Gaussian and have exponential tails.

description: While voice user interfaces offer increased accessibility due to hands-free and eyes-free interactions, older adults often have challenges such as constructing structured requests and perceiving how such devices operate. Voice-first user interfaces have the potential to address these challenges by enabling multimodal interactions. Standalone voice + touchscreen Voice Assistants (VAs), such as Echo Show, are specific types of devices that adopt such interfaces and are gaining popularity. However, the affordances of the additional touchscreen for older adults are unknown. Through a 40-day real-world deployment with older adults living independently, we present a within-subjects study (N = 16; age M = 82.5, SD = 7.77, min. = 70, max. = 97) to understand how a built-in touchscreen might benefit older adults during device setup, conducting self-report diary survey, and general uses. We found that while participants appreciated the visual outputs, they still preferred to respond via speech instead of touch. We identified six design implications that can inform future innovations of senior-friendly VAs for managing healthcare and improving quality of life.

description: We discovered a near room temperature lead-free relaxor-ferroelectric (Ba0.6Bi0.2Li0.2)TiO3 (BBLT) having A-site compositional disordered ABO3 perovskite structure. Microstructure-property relations revealed that the chemical inhomogeneities and development of local polar nano regions (PNRs) are responsible for dielectric dispersion as a function of probe frequencies and temperatures. Rietveld analysis indicates mixed crystal structure with 80% tetragonal structure (space group P4mm) and 20% orthorhombic structure (space group Amm2) which is confirmed by the high resolution transmission electron diffraction pattern. Dielectric constant and tangent loss dispersion with and without illumination of light obey nonlinear Vogel-Fulture relation. It shows slim polarization-hysteresis (P-E) loops and excellent displacement coefficients (d33 ~ 233 pm/V) near room temperature, which gradually diminish near the maximum dielectric dispersion temperature (Tm). The underlying physics for light-sensitive dielectric dispersion was probed by X-ray photon spectroscopy (XPS) which strongly suggests that mixed valence of bismuth ions, especially Bi5+ ions, are responsible for most of the optically active centers. Ultraviolet photoemission measurements showed most of the Ti ions are in 4+ states and sit at the centers of the TiO6 octahedra, which along with asymmetric hybridization between O 2p and Bi 6s orbitals appears to be the main driving force for net polarization. This BBLT material may open a new path for environmental friendly lead-free relaxor-ferroelectric research.

description: The industrial activities related to phosphate mining and treatment constitute a threat to the population and its environment at Hahotoé and Kpémé (Togo) and released uncontrolled concentrations of toxic heavy metals that polluting soils, vegetation and water. The assessment of the pollution level would be useful for remediation, safeguard and prediction of risk to the environment and public. This study aims to assess the pollution level related to heavy metals in the soils, water and leaves at the phosphate mining (Hahotoé) and treatment (Kpémé) sites using spectroscopic techniques. Pollution indices such as contam- ination factor, degree of contamination, potential ecological risk index, pollution load index and heavy metal pollution index were used to achieve this goal. The average concentrations of Cd, Cr, Cu, Ni, Pb and Zn were investigated in the soils, leaves and water samples from the studied areas using the ZEEnit 700 with acetylene-air flame atomic spectrometer. High average concentrations of heavy metals were found in the samples exceeding the WHO limits. Heavy metal pollution index was used to assess the wa- ter quality with respect to heavy metals and very high value was found of 1168.84 at Kpémé and 733.58 at Hahotoé exceeding the critical value of 100. The results show unacceptable water quality for drinking on these sites. This study must help to design measures to reduce the pollutants released in the areas. The concerned issue poses a public health threat, so stakeholders would act in controlling the pollution level.

description: Transit and radial velocity observations indicate a dearth of sub-Jupiter--mass planets on short-period orbits, outlined roughly by two oppositely sloped lines in the period--mass plane. We interpret this feature in terms of high-eccentricity migration of planets that arrive in the vicinity of the Roche limit, where their orbits are tidally circularized, long after the dispersal of their natal disk. We demonstrate that the two distinct segments of the boundary are a direct consequence of the different slopes of the empirical mass--radius relation for small and large planets, and show that this relation also fixes the mass coordinate of the intersection point. The period coordinate of this point, as well as the detailed shape of the lower boundary, can be reproduced with a plausible choice of a key parameter in the underlying migration model. The detailed shape of the upper boundary, on the other hand, is determined by the post-circularization tidal exchange of angular momentum with the star and can be reproduced with a stellar tidal quality factor $Q^\prime_*\sim10^6$.

description: Lineare Approximation stellt einen Zugang zur Differentialrechnung dar, der im Mathematikunterricht der Sekundarstufe I nur selten eine Rolle spielt, jedoch in der Mathematik aktuell wie auch historisch von Bedeutung ist. Im Artikel wird ein Ausschnitt einer Konzeption eines Unterrichtsgangs vorgestellt, der den in der Schule üblichen Weg der Einführung der Differentialrechnung verlässt und sich diesem Gebiet über die lineare Approximation nähert. Der Zusammenhang zum Aspekt der mittleren und lokalen Änderung wird dabei jedoch nicht aus dem Blick verloren. Chancen und Hürden werden aufgezeigt.

description: We introduce a variational implementation of cluster perturbation theory (CPT) to address the dynamics of spin systems driven out of equilibrium. We benchmark the method with the quantum Ising model subject to a sudden quench of the transverse magnetic field across the transition or within a phase. We treat both the one-dimensional case, for which an exact solution is available, as well the two-dimensional one, for which has to resort to numerical results. Comparison with exact results shows that the approach provides a quite accurate description of the real-time dynamics up to a characteristic time scale $τ$ that increses with the size of the cluster used for CPT. In addition, and not surprisingly $τ$ is small for quenches across the equilibrium phase transition, but can be quite larger for quenches within the ordered or disordered phases.

description: Context. Known TeV sources detected by major Cerenkov telescopes are investigated to identify possible MeV-GeV gamma-ray counterparts. Aims. A systematic study of the known sources in the web-based TeVCat Catalog has been performed to search for possible gamma-ray counterpart on the AGILE data collected during the first period of operations in observing pointing mode. Methods. For each TeV source, a search for a possible gamma-ray counterpart based on a multi-source Maximum Likelihood algorithm is performed on the AGILE data taken with the GRID instrument from July 2007 to October 2009. Results. In case of high-significance detection, the average gamma-ray flux is estimated. For the cases of low-significance detection the 95 % Confidence Level (C.L.) flux upper limit is given. 52 TeV sources out of 152 (corresponding to ~34 % of the analysed sample) show a significant excess in the AGILE data covering the pointing observation period. Conclusions. This analysis found 26 new AGILE sources with respect to the AGILE reference catalogs, 15 of which are Galactic, 7 are extragalactic and 4 are unidentified. Detailed tables with all available information on the analysed sources are presented.

description: Based on Son-Yamamoto relation obtained for transverse part of triangle axial anomaly in ${\rm QCD}_4$, we derive its analog in two-dimensional system. It connects the transverse part of mixed vector-axial current two-point function with diagonal vector and axial current two-point functions. Being fully non-perturbative, this relation may be regarded as anomaly matching for conductivities or certain transport coefficients depending on the system. We consider the holographic RG flows in holographic Yang-Mills-Chern-Simons theory via the Hamilton-Jacobi equation with respect to the radial coordinate. Within this holographic model it is found that the RG flows for the following relations are diagonal: Son-Yamamoto relation and the left-right polarization operator. Thus the Son-Yamamoto relation holds at wide range of energy scales.

description: Prozesse der Konstruktion mathematischen Wissens in sozialer Interaktion lassen sich nach Bikner-Ahsbahs durch die drei kollektiven epistemischen Handlungen des Sammelns mathematischer Einheiten, des Verknüpfens dieser Einheiten, und des Sehens mathematischer Strukturen beschreiben (SVSt-Modell, Bikner-Ahsbahs, 2005). Bisher wurden solche epistemischen Prozesse vor allem auf Basis sprachlicher Äußerungen untersucht. Soziale Interaktionen bestehen jedoch aus weitaus mehr als nur aus Sprache allein. Eine Berücksichtigung der nicht-sprachlichen Mittel kann somit zu einem besseren Verständnis sozialer Lernprozesse führen. Gesten scheinen eine besondere Rolle spielen, wenn mathematisches Wissen noch nicht explizit zugänglich ist (siehe z.B. Arzarello & Edwards, 2005). Diesem Ansatz folgend beschäftigte sich das hier vorgestellte Promotionsprojekte (gefördert von der Zentralen Forschungsförderung der Universität Bremen) mit der Frage, wie Gesten zu Prozessen mathematischer Wissenskonstruktion in sozialer Interaktion beitragen können, um Bikner-Ahsbah‘ bestehende Theorie epistemischer Prozesse um eine semiotische Perspektive zu erweitern. Dieser Beitrag stellt einige Ergebnisse des Projektes zusammengefasst dar. Es wurden folgende Teilfragen gestellt: - Wie tragen Gesten in sozialen Prozessen mathematischer Wissenskonstruktion dazu bei mathematische Objekte darzustellen? Wie spielen sie hierbei mit Sprache und Inskriptionen zusammen? - Wie tragen Gesten dazu bei epistemisch zu handeln? Welche förderlichen Arten des Gestengebrauchs lassen sich feststellen?

description: We theoretically predict a generation of a current in Weyl semimetals by applying circularly polarized light. The electric field of the light can drive an effective magnetic field of order of ten Tesla. For lower frequency light, a non-equilibrium spin distribution is formed near the Fermi surface. Due to the spin-momentum locking, a giant electric current proportional to the effective magnetic field is induced. On the other hand, higher frequency light realizes a quasi-static Floquet state with no induced electric current. We discuss relevant materials and estimate order of magnitude of the induced current.

Mass segregation in star clusters is not energy equipartition

description: Mass segregation in star clusters is often thought to indicate the onset of energy equipartition, where the most massive stars impart kinetic energy to the lower-mass stars and brown dwarfs/free floating planets. The predicted net result of this is that the centrally concentrated massive stars should have significantly lower velocities than fast-moving low-mass objects on the periphery of the cluster. We search for energy equipartition in initially spatially and kinematically substructured N-body simulations of star clusters with N = 1500 stars, evolved for 100 Myr. In clusters that show significant mass segregation we find no differences in the proper motions or radial velocities as a function of mass. The kinetic energies of all stars decrease as the clusters relax, but the kinetic energies of the most massive stars do not decrease faster than those of lower-mass stars. These results suggest that dynamical mass segregation -- which is observed in many star clusters -- is not a signature of energy equipartition from two-body relaxation.
