description: We consider a class of impulse control problems for general underlying strong Markov processes on the real line, which allows for an explicit solution. The optimal impulse times are shown to be of threshold type and the optimal threshold is characterized as a solution of a (typically nonlinear) equation. The main ingredient we use is a representation result for excessive functions in terms of expected suprema.

description: This article proposes a simplified space vector pulse-width modulation (SVPWM) technique five-leg inverter with dual three-phase output. An idea to fed the dual tree-phase machine by the multiphase voltage source inverters (VSIs) is not new. Dual- and multi-motor drive systems are widely used in the industry applications. The most popular fields are: electric vehicles (EVs) and traction systems. Moreover, the specific characteristic of the dual-drive systems allow to use them in the paper and textile production process. Mostly these solutions utilize carrier-based PWM (CBPWM) techniques for the output voltage generation, however the SVPWM techniques might be also used for this purpose. The main idea of this paper is to simplify the modulation process and obtain the similar algorithms complexity and execution times for the space-vector and carrier-based PWM techniques. The proposed SVPWM strategy allows to decrease the number of calculations at the initial stage of the algorithm. The output voltages for both loads/motors can be generated independently, with different frequencies and amplitudes. Simulation results were obtained using the PLECS software package. The experimental investigation with RL load were conducted as well. The carried tests proved the effectiveness of the proposed modulation strategy. All results are shown in this paper.

description: Low-energy quasiparticle excitations in the superconducting (SC) state of UBe$_{13}$ were studied by means of specific-heat ($C$) measurements in a rotating field. Quite unexpectedly, the magnetic-field dependence of $C(H)$ is linear in $H$ with no angular dependence at low fields in the SC state, implying that the gap is fully open over the Fermi surfaces, in stark contrast to the previous expectation. In addition, a characteristic cubic anisotropy of $C(H)$ was observed above 2~T with a maximum (minimum) for $H$ $||$ $[001]$ ($[111]$) within the $(1\bar{1}0)$ plane, both in the normal as well as in the SC states. This oscillation possibly originates from the anisotropic response of the heavy quasiparticle bands, and might be a key to understand the unusual properties of UBe$_{13}$.

description: Creative thinking is one of the key skills of human intelligence that leads to the generation of valuable and novel ideas. It is also considered essential for developing students' capabilities and their cognition. While recent advances in artificial intelligence and machine learning technologies have been shown to promote critical thinking, learner interfaces that support the 'creative thinking' of students are scarce. In this work, we present a design system for facilitating students’ creative writing abilities. We follow a learner-centered design methodology, and evaluate the design system functionally, visually, and for accessibility, with a group of twelve students as representative users. The results show that designing alongside the target audience helps to rapidly identify user needs, individual preferences, and diverse viewpoints, and shows that the designed system performs better in all tested aspects including learner satisfaction, ownership, and self-efficacy.

description: A brief introduction of the relationship of string percolation to the Quantum Chromo Dynamics (QCD) phase diagram is presented. The behavior of the Polyakov loop close to the critical temperature is studied in terms of the color fields inside the clusters of overlapping strings, which are produced in high energy hadronic collisions. The non-Abelian nature of the color fields implies an enhancement of the transverse momentum and a suppression of the multiplicities relative to the non overlapping case. The prediction of this framework are compared with experimental results from the SPS, RHIC and LHC for $pp$ and AA collisions. Rapidity distributions, probability distributions of transverse momentum and multiplicities, Bose-Einstein correlations, elliptic flow and ridge structures are used to evaluate these comparison. The thermodynamical quantities, the temperature, and energy density derived from RHIC and LHC data and Color String Percolation Model (CSPM) are used to obtain the shear viscosity to entropy density ratio ($η/s$). It was observed that the inverse of ($η/s$) represents the trace anomaly $Δ=(\varepsilon-3P)/T^{4}$. Thus the percolation approach within CSPM can be successfully used to describe the initial stages in high energy heavy ion collisions in the soft region in high energy heavy ion collisions. The thermodynamical quantities, temperature and the equation of state are in agreement with the lattice QCD calculations. Thus the clustering of color sources has a clear physical basis although it cannot be deduced directly from QCD.

Von diesen gewonnenen Kenntnissen und eventuell folgenden Kursanpassungen profitieren jedoch frühestens die Teilnehmenden der nächsten Kursdurchführung. Lehrenden bereits während der Kursdurchführung Einsichten zu geben bietet die Möglichkeit frühzeitig auf eventuelle Probleme zu reagieren. Studierende können ihren eigenen Lernpfad reflektieren und bei Bedarf anpassen. In diesem Beitrag wird eine Anwendung vorgestellt welche einmal täglich die als xAPI Statements gesammelten Daten der letzten 24 Stunden aus dem Lernmanagementsystem Moodle analysiert und die Lernpfade der einzelnen Kurse erweitert. Um eine skalierende Lösung bereitzustellen, werden Techniken des Streaming Process Minings angewandt.

description: The rapid growth and obsolescence of knowledge cause uncertainty for university actors, such as students, teachers, administrative staff, and technology vendors. They must find new ways of dealing with hindering assumptions, and behaviors toward learning and teaching. To overcome these and achieve educational goals, it is essential to question ineffective ways of teaching and learning, adopt new education processes, and discard inadequate beliefs and procedures. This process is known as unlearning. In this position paper, we explore the potential of unlearning for mitigating educational challenges through unlearning. From a socio-technical perspective, we highlight the value of unlearning as a tool for tackling different challenges in university contexts. Finally, we identify central problem spaces stimulating further discussions.

description: We report on the effect of substrate temperature (T) on both local structure and long-wavelength fluctuations of polycrystalline CdTe thin films deposited on Si(001). A strong T-dependent mound evolution is observed and explained in terms of the energy barrier to inter-grain diffusion at grain boundaries, as corroborated by Monte Carlo simulations. This leads to transitions from uncorrelated growth to a crossover from random-to-correlated growth and transient anomalous scaling as T increases. Due to these finite-time effects, we were not able to determine the universality class of the system through the critical exponents. Nevertheless, we demonstrate that this can be circumvented by analyzing height, roughness and maximal height distributions, which allow us to prove that CdTe grows asymptotically according to the Kardar-Parisi-Zhang (KPZ) equation in a broad range of T. More important, one finds positive (negative) velocity excess in the growth at low (high) T, indicating that it is possible to control the KPZ non-linearity by adjusting the temperature.

description: We present VLA H I and 6 cm radio continuum observations of the spiral NGC 3145 and H I observations of its two companions, NGC 3143 and PGC 029578. In optical images NGC 3145 has stellar arms that appear to cross, forming "X"-features. Our radio continuum observations rule out shock fronts at 3 of the 4 "X"-features. In the middle-to-outer disk, the H I line-profiles of NGC 3145 are skewed. Relative to the disk, the gas in the skewed wing of the line-profiles has z-motions away from us on the approaching side of the galaxy and z-motions of about the same magnitude (about 40 km/s) towards us on the receding side. These warping motions imply that there has been a perturbation with a sizeable component perpendicular to the disk over large spatial scales. Two features in NGC 3145 have velocities indicating that they are out-of-plane tidal arms. One is an apparent branch of a main spiral arm; the velocity of the branch is 150 km/s greater than the spiral arm where they appear to intersect in projection. The other is an arm that forms 3 of the "X"-features. It differs in velocity by 56 km/s from the disk at the same projected location. Based on its SFR and H I properties, NGC 3143 is the more likely of the two companions to have interacted with NGC 3145 recently. A simple analytic model demonstrates that an encounter between NGC 3143 and NGC 3145 is a plausible explanation for the observed warping motions in NGC 3145.

description: It will be shown in this paper that new sensitive phase based one-dimensional photonic crystal devices can be developed if existing problems can somehow be overcome. From such perspective, the major problems associated can be states ad rapid change of light intensity around the defect mode in one-dimensional systems and the effect of the substrate. Some of the techniques which are used to overcome such problems is to construct a defective one-dimensional photonic crystal in a heterostructure or an asymmetric structure. Now considering this, we can see that the phase of asymmetric one-dimensional photonic crystals along with couple defects are shown in this paper. As a immediate extension of this, a phase modulator as well as a phase switch with very high sensitivity are demonstrated.

description: This policy brief features a successful solution to low economic productivity through the development of a Central Business District (CBD). This was achieved in the 2010s in Stoke-on-Trent – a medium-size polycentric industrial city in central England, coping with economic restructuring and demographic decline. Building on local knowledge and the stakeholders’ experience in implementing this project, this brief demonstrates how to develop a solid evidence base, design and build a CBD that works effectively for the whole city. The key lesson learnt is that to build a CBD, one should utilise non-traditional co-production and experimental methods for managing a major project in an uncertain and risky environment, combining technical skills and expertise, whilst tapping into the day-to-day knowledge and experience of the local community. The brief offers a set of policy recommendations on enabling mechanisms for an effective CBD delivery.

description: In Korea, there are more than 1,500 traditional retail markets selling agricultural and other products to consumers, but the number has gone down a lot recently due to increasing number of discount stores and department stores. The purpose of this paper is to analyze consumers' recognition of traditional retail markets using a multinomial logit model and suggest strategies to promote the traditional retail markets. The results of the analysis present several implications: First, most consumers often buy small amount of products and are satisfied with the quality of products in the traditional retail markets. Second, investment in parking facilities for consumers is the most important physical factor. Third, the difference in consumers' characteristics requires differentiation of strategy on physical or non-physical factors to promote the traditional retail markets.

description: Although the utilization of AI in education has grown considerably in the last decade, its environmental impact has been disregarded thus far. In this paper, we examine the energy consumption of Artificial Intelligence (AI) in education, which is employed, for instance, in adaptive learning. We measured the energy requirements of four AI implementations used on the student learning platform orthografietrainer.net. We found that two of the implementations have notably low energy and CPU demands in comparison to the baseline, while in two other implementations, these parameters are significantly higher. We conclude that more attention should be paid to whether the comparable performance of AI in education can be achieved with lower energy consumption.

description: The purpose was to examine the cooling performance of the air ventilation clothing. For this, a 3D numerical model is developed for air ventilation clothing. The detailed geometric model was developed based on 3D body scanning. Meshing and analysis were conducted in Ansys ICEM CFD and Ansys FLUENT, respectively. The effect of airflow rate, fan size, and convective heat losses on the cooling performance of the air ventilation clothing was analyzed. Results showed that the cooling performance of the clothing increased as the air flow rate increased. Area-weighted average torso heat flux increased by 68.18 % when the air flow rate increased from 10 l/s to 20 l/s, and the heat removal was found to be highest and lowest at the lower back and upper chest, respectively, compared to other body segments. The cooling performance of the air ventilation clothing (area-weighted heat flux of the torso) decreased as fan size increased for a given flow rate. The effect of the fan dimensions on the upper chest, upper arm, and shoulder segments of the body is found to be negligible. The effect of convective heat loss from the clothing was found to be negligible on body heat removal. It is observed that the effect of airflow rate on the cooling performance of the clothing is much higher than that of other parameters (like fan size and convective heat transfer coefficient).

description: Das Interesse an Lernumgebungen für Virtual Reality hat in den letzten Jahren zugenommen. Eine Möglichkeit, die Effektivität dieser Lernumgebungen messbar zu machen, besteht im Einsatz von Learning Analytics. Allerdings erfordert die Einarbeitung von Programmier*innen umfangreiche Kenntnisse über Learning Analytics und ist häufig aufgrund von Zeitmangel nur oberflächlich. Um Hürden entgegenzuwirken, wurde OmiLAXR (ehemals EduXR) entwickelt, eine vielfältige Unterstützung für Entwickelnde von VR-Applikationen in Unity. Dieser Beitrag stellt kurz Prototypen und ein Evaluationskonzept von Entwicklungsprozessen mit vielfältigem Learning Analytics Ökosystem vor. Ziel ist eine anschließende systematische Anforderungsanalyse für die technische Perspektive auf Learning Analytics Infrastrukturen.

description: Holographic diffractive optical elements (HDOEs) are very fascinating optical devices based on the holography technique and have been spotlighted in augmented reality (AR) applications recently. The HDOEs have optically see-through property due to their high angular-selectivity, which has extensive potential to be employed as an imaging combiner for the AR devices. Various functions of optical components, including a mirror, a lens, and a diffuser, can be implemented with the thin HOE film. This advanced functionality can replace the conventional bulky optics with HOEs for a compact form factor in AR near-eye displays. In addition, multi-function and multilevel HDOEs can be realized with multiplexed recording, and mass production based on the optical recording is possible. Due to these powerful advantages, the HDOEs have especially tremendous potential for AR display systems.

description: In a recent article by S. Banerji et. al. [Optica, 6(6)], the authors claimed that diffractive optic elements based on multilevels i.e. multilevel diffractive lenses (MDLs), when designed properly, can exceed the performance of metalenses. In this commentary, I seek to convey opinion on the subject.

description: In order to reduce the cognitive load of students, the web app getch supports documenting, structuring and presenting individual or joint learning paths using different types of media (recordings, writings, photographs, videos, formulas or files) depending on a learner's individual preferences. In addition, it allows for various forms of cooperative and co-constructive learning. It was designed to help balance the field of tension between personalized and cooperative learning that is constitutive for inclusive as well as digital learning settings. Due to its conceptual openness, getch can be used across subjects and supports participative learning processes.
title: Global dynamics of two population models with spatial heterogeneity

description: Mathematical models provide powerful tools to explain and predict population dynamics. A central problem is to study the long-term behavior of modeling systems. The patch models and reaction-diffusion models are widely applied to describe spatial heterogeneity and habitat connectivity. Basic reproduction number R₀ plays an important role in mathematical biology. In epidemiology, R₀ stands for the expected number of secondary cases produced in a completely susceptible population by a typical infective individual. The value of R₀ can determines the persistence or extinction of population. Nowadays, characterizing the basic reproduction number due to the effects of parameters becomes very significant for predicting and controlling disease transmission. This thesis consists of three chapters. In Chapter 1, we investigate the effect of spatial heterogeneity on the basic reproduction number for an SIS epidemic patch model, and compute R₀ numerically to show the influence of the spatial heterogeneity and movement. Chapter 2 is devoted to the study of the global dynamics of a reaction diffusion model arising from the dynamics of a kind of mosquitos named A. aegypti in Brazil. We first prove the global existence and boundedness of the solutions. Secondly, we establish the threshold type dynamics in terms of the basic reproduction ratio R₀. In Chapter 3, we briefly summarize the main results and present some future works.

description: The solute dynamics in a symmetrical poly (ethylene oxide)-poly (propylene oxide)-poly (ethylene oxide) (PEO-PPO-PEO) triblock copolymer, P-123 were studied in aqueous and saline solutions as a function of additives, temperature using spectroscopic techniques. We have chosen a hydrophobic solute Coumarin-6 (C-6) as probe to study the photophysics and rotational dynamics in the above systems. We found that the rotational dynamics of C-6 is hindered in saline solution compared to that in aqueous solution of P-123. Therefore, in the saline solution of P-123, C-6 faced more restricted environment compared to the aqueous solution of P-123. In the absence of saline, at a temperature higher than cmt, we observed that addition of 0.02 M n-hexanol decreases the rotational relaxation time compared to that in P-123. Whereas, addition of 0.02 M n-hexylamine the rotational relaxation remains almost same compared to that in P-123. Therefore, n-hexanol affect more on the solute dynamics compared to n-hexylamine because of its preferential partitioning in the micellar phase owing to its greater hydrophobic ranking compared to n-hexylamine. In the saline solution we observed that addition of 0.02 M n-hexanol on P-123 solution affect more on the rotational dynamics of C-6 compared to the addition of 0.02 M n-hexylamine.

description: Determination of Higgs self-interactions through the double Higgs production from gluon fusion is a major goal of current and future collider experiments. We point out this channel could help disentangle and resolve the nature of ultraviolet contributions to Higgs couplings to two gluons. Analytic properties of the double Higgs amplitudes near kinematic threshold are used to study features resulting from scalar and fermionic loop particles mediating the interaction. Focusing on the hh invariant mass spectrum, we consider the effect from anomalous top and bottom Yukawa couplings, as well as from scalar and fermionic loop particles. In particular, the spectrum at high hh invariant mass is sensitive to the spin of the particles in the loop.

description: We present a new method of finding protoclusters using tomographic maps of Ly$α$ Forest flux. We review our method of creating tomographic flux maps and discuss our new high performance implementation, which makes large reconstructions computationally feasible. Using a large N-body simulation, we illustrate how protoclusters create large-scale flux decrements, roughly 10 $h^{-1}$Mpc across, and how we can use this signal to find them in flux maps. We test the performance of our protocluster finding method by running it on the ideal, noiseless map and tomographic reconstructions from mock surveys, and comparing to the halo catalog. Using the noiseless map, we find protocluster candidates with about 90% purity, and recover about 75% of the protoclusters that form massive clusters ($> 3 \times 10^{14} \, h^{-1} M_{\odot}$). We construct mock surveys similar to the ongoing COSMOS Lyman-Alpha Mapping And Tomography Observations (CLAMATO) survey. While the existing data has an average sightline separation of 2.3 $h^{-1}$Mpc, we test separations of 2 - 6 $h^{-1}$Mpc to see what can be tolerated for our application. Using reconstructed maps from small separation mock surveys, the protocluster candidate purity and completeness are very close what was found in the noiseless case. As the sightline separation increases, the purity and completeness decrease, although they remain much higher than we initially expected. We extended our test cases to mock surveys with an average separation of 15 $h^{-1}$Mpc, meant to reproduce high source density areas of the BOSS survey. We find that even with such a large sightline separation, the method can still be used to find some of the largest protoclusters.

description: The integration of multimedia elements into educational materials has the potential to improve students' engagement and understanding. In this paper, we present the development of an hyperaudio player that represents textbook information in auditory format, providing a joint playback experience for groups of users. Additionally, the Moodle-based hyperaudio player includes a voice chat feature, allowing for real-time discussions among users when the audio is paused. We aim to investigate the appropriateness of hyperaudio as a new online learning format.

description: Intel and AMD support the Carry-less Multiplication (CLMUL) instruction set in their x64 processors. We use CLMUL to implement an almost universal 64-bit hash family (CLHASH). We compare this new family with what might be the fastest almost universal family on x64 processors (VHASH). We find that CLHASH is at least 60% faster. We also compare CLHASH with a popular hash function designed for speed (Google's CityHash). We find that CLHASH is 40% faster than CityHash on inputs larger than 64 bytes and just as fast otherwise.

description: Longer phases without interaction or a later start into task processing are often related to problems in collaborative learning. Teams that exhibit such patterns of teamwork are more likely to underperform or fail in collaboration. Automated alerts are a way to contact such student teams, make them aware of unfavourable interaction patterns and offer support. An adequate design of such alerts is a basis for their efficacy. In this study, we investigated students’ (N = 39) attitudes towards alerts and ana-lysed which types of automated alerts students prefer. Based on findings of previous studies, we have designed three types of alerts – “impersonal-with response”, “personal-with response” and “information only”. Students in our study mainly preferred “personal-with response”. However, in-depth investigation revealed restrictions. Based on results, we give recommendations for the design of automated alerts.
