Creating a “Teaching Portfolio Chart” for reflection and clarifying one’s own teaching philosophy
Creators: name: Kurita, Kayoko

Publisher: name: ETH Learning and Teaching Journal
Year: 2020

description: The Teaching Portfolio Chart (TP Chart) is a worksheet for reflecting on teaching, distilling one’s teaching philosophy, connecting philosophy and practical methodology, and setting future goals. It was developed based on the concept of the Teaching Portfolio by Seldin, Meller and Seldin (2010). The advantages of the TP Chart are: (1) helping the creator reflect on all their educational activities to find their teaching philosophy with short creation time; (2) the process of creating a TP Chart can support one’s reflections, step by step and in an organized way; and (3) an AP Chart presents a singular overview of one’s teaching, making sharing with others easy. In this paper we introduce the structure and features of the TP Chart, explain its creation process, and then discuss its future potential and challenges.

description: Galaxy clusters are considered to be gigantic reservoirs of cosmic rays (CRs). Some of the clusters are found with extended radio emission, which provides evidence for the existence of magnetic fields and CR electrons in the intra-cluster medium (ICM). The mechanism of radio halo (RH) emission is still under debate, and it has been believed that turbulent reacceleration plays an important role. In this paper, we study the reacceleration of CR protons and electrons in detail by numerically solving the Fokker-Planck equation, and show how radio and gamma-ray observations can be used to constrain CR distributions and resulting high-energy emission for the Coma cluster. We take into account the radial diffusion of CRs and follow the time evolution of their one-dimensional distribution, by which we investigate the radial profile of the CR injection that is consistent with the observed RH surface brightness. We find that the required injection profile is non-trivial, depending on whether CR electrons have the primary or secondary origin. Although the secondary CR electron scenario predicts larger gamma-ray and neutrino fluxes, it is in tension with the observed RH spectrum. In either scenario, we find that galaxy clusters can make a sizable contribution to the all-sky neutrino intensity if the CR energy spectrum is nearly flat.

description: In this paper we use the conformal teleparallel gravity to study an isotropic and homogeneous Universe which is settled by the FRW metric. We solve the field equations and we obtain the behavior of some cosmological parameters such as scale factor, deceleration parameter and the energy density of the perfect fluid which is the matter field of our model. The field equations, that we called modified Friedmann equations, allow us to define a dark fluid, with dark energy density and dark pressure, responsible for the acceleration in the Universe.

description: Closely motivated by financial considerations, we develop an integration theory which is not classical i.e. it is not necessarily associated to a measure. The base space, denoted by $\mathcal{S}$ and called a trajectory space, substitutes the set $Ω$ in probability theory and provides a fundamental structure via conditional subsets $\mathcal{S}_{(S,j)}$ that allows the definition of conditional integrals. The setting is a natural by-product of no arbitrage assumptions that are used to model financial markets and games of chance (in a discrete infinite time framework). The constructed conditional integrals can be interpreted as required investments, at the conditioning node, for hedging an integrable function, the latter characterized a.e. and in the limit as we increase the number of portfolios used. The integral is not classical due to the fact that the original vector space of portfolio payoffs is not a vector lattice. In contrast to a classical stochastic setting, where price processes are associated to conditional expectations (with respect to risk neutral measures), we uncover a theory where prices are naturally given by conditional non-lattice integrals. One could then study analogues of classical probabilistic notions in such non-classical setting, the paper stops after defining trajectorial martingales the study of which is deferred to future work.

description: Fractured metal fragments with rough and irregular surfaces are often found at crime scenes. Current forensic practice visually inspects the complex jagged trajectory of fractured surfaces to recognize a ``match'' using comparative microscopy and physical pattern analysis. We developed a novel computational framework, utilizing the basic concepts of fracture mechanics and statistical analysis to provide quantitative match analysis for match probability and error rates. The framework employs the statistics of fracture surfaces to become non-self-affine with unique roughness characteristics at relevant microscopic length scale, dictated by the intrinsic material resistance to fracture and its microstructure. At such a scale, which was found to be greater than two grain-size or micro-feature-size, we establish that the material intrinsic properties, microstructure, and exposure history to external forces on an evidence fragment have the premise of uniqueness, which quantitatively describes the microscopic features on the fracture surface for forensic comparisons. The methodology utilizes 3D spectral analysis of overlapping topological images of the fracture surface and classifies specimens with very high accuracy using statistical learning. Cross correlations of image-pairs in two frequency ranges are used to develop matrix variate statistical models for the distributions among matching and non-matching pairs of images, and provides a decision rule for identifying matches and determining error rates. A set of thirty eight different fracture surfaces of steel articles were correctly classified. The framework lays the foundations for forensic applications with quantitative statistical comparison across a broad range of fractured materials with diverse textures and mechanical properties.

Beyond the student-centered higher education classroom: The student-centered ecosystems framework
Creators: name: Hoidn, Sabine
Publisher: name: ETH Learning and Teaching Journal
Year: 2020

description: In student-centered classrooms less time is devoted to plain lecturing (“telling”) and more time to meaningful and challenging tasks and activities that increase the level of students’ cognitive engagement with disciplinary content as well as active student participation (Hoidn, 2017, 2019). Hoidn and Klemenčič (2020a) argue, however, that student-centered learning and teaching processes need to be thoughtfully embedded in broader institutional ecosystems – so-called student-centered ecosystems which, in turn, are also connected to and influenced by the wider political, economic, social and cultural contexts in which HEIs operate. This paper introduces student-centered ecosystems consisting of five main components which serve as indicators of the presence of student centered learning and teaching (SCLT) in a given educational institution or study program: (1) Curriculum, pedagogy and assessment; (2) Teaching and learning support; (3) Quality of learning and teaching; (4) Governance and administration; and (5) Policies and finance (Klemenčič & Hoidn, 2020).

description: The generalized Klein-Nishina formula for Compton scattering of charged particles by a finite train of pulses is derived in the framework of quantum electrodynamics. The formula also applies to classical Thomson scattering provided that frequencies of generated radiation are smaller that the cut-off frequency. The validity of the formula for incident pulses of different durations is illustrated by numerical examples. The positions of the well-resolved Compton peaks, with the clear labeling by integer orders, opens up the possibility of the precise diagnostics of properties of relativistically intense, short laser pulses. This includes their peak intensity, the carrier-envelope phase, and their polarization properties.

description: This paper introduces dynamic mechanism design in an elementary fashion. We first examine optimal dynamic mechanisms: We find necessary and sufficient conditions for perfect Bayesian incentive compatibility and formulate the optimal dynamic mechanism problem. We next examine efficient dynamic mechanisms: We establish the uniqueness of Groves mechanism and investigate budget balance of the dynamic pivot mechanism in some detail for a bilateral trading environment. This introduction reveals that many results and techniques of static mechanism design can be straightforwardly extended and adapted to the analysis of dynamic settings.

description: Virtual exchange is an online form of internationalization at home. Students from different countries collaborate in small, international groups on tasks joined by a common theme. They combine their expertise when solving problems together. The teachers act as mentors, providing facilitation and support for the students during the virtual exchange. The student teams work independently by selecting the tools for the collaboration, allocating the tasks and creating the group’s final product. Virtual exchange is a transnational learning opportunity which enables students to learn and practice how to efficiently combine and make use of their digital, visual, critical, linguistic and intercultural competencies (Boche, 2014) in order to feel ready for and empowered in working life.

description: In this study, we propose a novel approach to predict the distances of the detected objects in an observed scene. The proposed approach modifies the recently proposed Convolutional Support Estimator Networks (CSENs). CSENs are designed to compute a direct mapping for the Support Estimation (SE) task in a representation-based classification problem. We further propose and demonstrate that representation-based methods (sparse or collaborative representation) can be used in well-designed regression problems. To the best of our knowledge, this is the first representation-based method proposed for performing a regression task by utilizing the modified CSENs; and hence, we name this novel approach as Representation-based Regression (RbR). The initial version of CSENs has a proxy mapping stage (i.e., a coarse estimation for the support set) that is required for the input. In this study, we improve the CSEN model by proposing Compressive Learning CSEN (CL-CSEN) that has the ability to jointly optimize the so-called proxy mapping stage along with convolutional layers. The experimental evaluations using the KITTI 3D Object Detection distance estimation dataset show that the proposed method can achieve a significantly improved distance estimation performance over all competing methods. Finally, the software implementations of the methods are publicly shared at https://github.com/meteahishali/CSENDistance.

description: In complex materials various interactions play important roles in determining the material properties. Angle Resolved Photoelectron Spectroscopy (ARPES) has been used to study these processes by resolving the complex single particle self energy $Σ(E)$ and quantifying how quantum interactions modify bare electronic states. However, ambiguities in the measurement of the real part of the self energy and an intrinsic inability to disentangle various contributions to the imaginary part of the self energy often leave the implications of such measurements open to debate. Here we employ a combined theoretical and experimental treatment of femtosecond time-resolved ARPES (tr-ARPES) and show how measuring the population dynamics using tr-ARPES can be used to separate electron-boson interactions from electron-electron interactions. We demonstrate the analysis of a well-defined electron-boson interaction in the unoccupied spectrum of the cuprate Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+x}$ characterized by an excited population decay time constant $τ_{QP}$ that maps directly to a discrete component of the equilibrium self energy not readily isolated by static ARPES experiments.

description: This ‘thought piece’ considers ways in which the concept of Circular Economy (CE) might be redefined within the innovation ecosystem. The findings of this report suggest that a distinction needs to be made between the innovation activities of circular economy SMEs as opposed to SMEs undertaking CE innovation, and that a CE programme for SMEs based on should be a focus for innovation policy. Through a literature review, a less reductive definition of the CE- traditionally associated with ‘recycling’- in sustainability innovation, emerges. The aim of this report is to provide insights to Innovate UK about how policy can support a CE paradigm shift that can fundamentally change the social and business mindsets around sustainability and CE implementation.

SOLID ROCKET MOTOR

description: Solid propellants are commonly used for civil and military applications because of their good trade-off between performances and cost. The size of full-scale solid-rocket motors (SRM) and their harsh operating conditions (high temperature, pressure above 5.0 MPa) makes experimental characterizations difficult to perform on real applications. Numerical simulation is a key part for the design of reliable set-ups but requires accurate physical models. This is the case for the ignition process that corresponds to a rapid transient phase for the composite material from ambient temperature to combustion [1]. Validation and adjustment for ignition models rely on the availability of accurate high-speed experimental data. But the available literature remains limited and often faces large uncertainty levels that make them unsuitable for accurate model-fitting approaches. In this context, ONERA is developing a complete experimental approach to follow surface temperature for small solid-propellant samples during the transient phase leading to ignition. The samples are placed in a high-pressure chamber filled up with pure nitrogen at 0.3 MPa. Ignition is obtained via surface irradiation by a high-power CO2 laser at 10.6 m. Two types of measurements devices are used simultaneously to follow surface temperature. Custom-made pyrometers provide spatially-averaged temperature data above 10 kHz. Two infra-red cameras provide spatially-resolved temperature measurement around 700 Hz. The present paper describes the full process to quantify solid-propellant surface temperature on an absolute scale. This involves surface emissivity measurement as well as detailed optical set-up calibration (sensor properties, optical characteristics). This also includes complete uncertainty evaluation to account for the various error sources. Since the radiative phenomena involved are highly non linear, a Monte Carlo approach was used to generate temperature errors in terms of temperature distributions that are not necessarily Gaussian. The complete approach is demonstrated here with a classical AP/HTPB solid-propellant composition. It is highly promising for the development of more accurate ignitions models that account for all physical phenomena. The measured temperature evolution with detailed error intervals will make it possible for model-sensitivity analysis with reliable data. References [1] M. W. Beckstead, K. Puduppakkam, P. Thakre, V.

description: Efficient method of moments (EMM) is used to fit the standard stochastic volatility model of various extensions to several daily financial time series. EMM matches to the score of the model determined by data analysis called the score generator. Discrepancies reveal characteristics of data that stochastic volatility models cannot approximate. The two score generators employed here are ‘semiparametric ARCH’ and ‘nonlinear nonparametric’. With the first, the standard model is rejected, although some extensions are accepted. With the second, all versions are rejected. The extensions required for an adequate fit are so elaborate that nonparametric specifications are probably more convenient.

description: We study multi-sensor fusion for 3D semantic segmentation that is important to scene understanding for many applications, such as autonomous driving and robotics. Existing fusion-based methods, however, may not achieve promising performance due to the vast difference between the two modalities. In this work, we investigate a collaborative fusion scheme called perception-aware multi-sensor fusion (PMF) to effectively exploit perceptual information from two modalities, namely, appearance information from RGB images and spatio-depth information from point clouds. To this end, we project point clouds to the camera coordinate using perspective projection, and process both inputs from LiDAR and cameras in 2D space while preventing the information loss of RGB images. Then, we propose a two-stream network to extract features from the two modalities, separately. The extracted features are fused by effective residual-based fusion modules. Moreover, we introduce additional perception-aware losses to measure the perceptual difference between the two modalities. Last, we propose an improved version of PMF, i.e., EPMF, which is more efficient and effective by optimizing data pre-processing and network architecture under perspective projection. Specifically, we propose cross-modal alignment and cropping to obtain tight inputs and reduce unnecessary computational costs. We then explore more efficient contextual modules under perspective projection and fuse the LiDAR features into the camera stream to boost the performance of the two-stream network. Extensive experiments on benchmark data sets show the superiority of our method. For example, on nuScenes test set, our EPMF outperforms the state-of-the-art method, i.e., RangeFormer, by 0.9% in mIoU. Our source code is available at https://github.com/ICEORY/PMF.

description: Die Stärke von Linked Open Data (LOD) ist die Verknüpfung von Informationen aus unterschiedlichsten dezentral gehosteten Wissensdomänen. Für die Geoinformatik haben sich beispielsweise community-basierende Datenrepositorien wie Wikidata, LinkedGeoData oder DBpedia gebildet. Leider haben all diese Linked Data Ressourcen in der Geo-Community bisher leider nur niederrangige Bedeutung erlangt. Die Gründe dafür sehen wir in nicht vorhandenen, leicht bedienbaren Tools für: Datenintegration in das Semantic Web (Semantic Uplift), Datenzugriff (Semantic Downlift), fehlende Query Capabilities in GeoSPARQL und die Anreicherung von GIS Daten mit Semantic Web Daten. In unserem Vortrag möchten wir Alternativen und Tools für diese Anwendungsfälle aufzeigen: (1) Das SPARQLing Unicorn QGIS Plugin zum vereinfachten Querying von SPARQL Endpoints, Anreicherung von Geodaten mit Semantic Web Inhalten, Konvertierung von Geodaten in RDF zur Integration in RDF Stores und Bearbeitung/Reprojektion von semantischen Geodaten. (2) postgis-jena und rdf4j-postgis die TripleStore Implementierungen um Query Capabilities, die aktuell noch nicht im GeoSPARQL Standard aber in PostGIS enthalten sind, erweitern. (3) SemanticWFS erlaubt es die Ergebnisse von SPARQL Queries als FeatureTypes eines WFS oder auch über OGC API Features bereitzustellen und somit die Verbindung der beiden Welten Geospatial Semantic Web und GIS Umgebungen.

description: In 2017, the Faculty of Science and Engineering at Manchester Metropolitan University began an initiative that led to the creation of over 2000 videos and screencasts to support students across all their departments. The videos cover solutions for tutorial problems, provide coursework briefing information, or support laboratory work and exam preparation. This paper reports the findings of the quantitative study to investigate the effectiveness of the initiative on unit performance. Whilst adjusting for key student characteristics, regression analysis was applied to measure the links between final unit marks of 1248 undergraduate students and their level of engagement with videos. A positive correlation was found, and a further qualitative study is now underway to elaborate on these results and to explain such impact.

description: Food science explores the fundamental relationships between the quality of food and its processing, as well as the effects of diet on health. Food chemistry and food analysis are two core disciplines needed to understand the complexity of food science. The integrated und interactive workbook developed at ETH helps to make the interconnectivity of disciplines visible. With theory texts, interactive videos, electronic dictionaries and quizzes for each individual chapter, the workbook promotes students’ active engagement and participation in the learning process inside and outside the lecture hall. Three different formats of the workbook, namely an e-textbook, a web-based platform and a mobile application, will be developed. These digital technologies create flexible learning spaces, can be used in flipped classroom settings, and support students’ academic learning process.

description: We study the asymptotic expansion for the Landau constants $G_n$, \begin{equation*} πG_{n}\sim \ln(16N)+γ+\sum^{\infty}_{k=1}\frac{α_k}{N^k} ~~\mbox{as} ~ n\rightarrow\infty, \end{equation*} where $N=n+1$, and $γ$ is Euler's constant. We show that the signs of the coefficients $α_{k}$ demonstrate a periodic behavior such that $(-1)^{\frac {l(l+1)} 2} α_{l+1}< 0$ for all $l$. We further prove a conjecture of Granath which states that $(-1)^{\frac {l(l+1)} 2} \varepsilon_l(N)<0$ for $l=0,1,2,\cdots$ and $n=0,1,2,\cdots$, $\varepsilon_l(N)$ being the error due to truncation at the $l$-th order term. Consequently, we also obtain the sharp bounds up to arbitrary orders of the form \begin{equation*} \ln(16N)+γ+\sum_{k=1}^{p}\frac{α_{k}}{N^{k}}

description: We present an experiment in which a one-bit memory is constructed, using a system of a single colloidal particle trapped in a modulated double-well potential. We measure the amount of heat dissipated to erase a bit and we establish that in the limit of long erasure cycles the mean dissipated heat saturates at the Landauer bound, i.e. the minimal quantity of heat necessarily produced to delete a classical bit of information. This result demonstrates the intimate link between information theory and thermodynamics. To stress this connection we also show that a detailed Jarzynski equality is verified, retrieving the Landauer's bound independently of the work done on the system. The experimental details are presented and the experimental errors carefully discussed

description: This paper investigates the ability of mixtures of affine, quadratic, and non-linear models to track the volatility in the term structure of interest rates. Term structure dynamics appear to exhibit pronounced time varying or stochastic volatility. Ahn et al. (Rev. Financial Stud. xx (2001) xxx) provide evidence suggesting that term structure models incorporating a set of quadratic factors are better able to reproduce term structure dynamics than affine models, although neither class of models is able to fully capture term structure volatility. In this study, we combine affine, quadratic and non-linear factors in order to maximize the ability of a term structure model to generate heteroskedastic volatility. We show that this combination entails a tradeoff between specification of heteroskedastic volatility and correlations among the factors. By combining factors, we are able to gauge the cost of this tradeoff. Using efficient method of moments (Gallant and Tauchen, Econometric Theory 12 (1996) 657), we find that augmenting a quadratic model with a non-linear factor results in improvement in fit over a model comprised solely of quadratic factors when the model only has to confront first and second moment dynamics. When the full dynamics are confronted, this result reverses. Since the non-linear factor is characterized by stronger dependence of volatility on the level of the factor, we conclude that flexibility in the specification of both level dependence and correlation structure of the factors are important for describing term structure dynamics.

description: Hybrid Rocket Engines (HREs) are a promising technology to achieve a cheaper, more sustainable and competitive access to space. So far, liquid rocket engines and solid rocket motors have been preferred over HREs for launcher applications. This is due to the low maturity of HREs, as well as challenges related to low regression rate, combustion inefficiency, oxidizer-to-fuel ratio (O/F) shift during operation and high residual inert mass. Nonetheless, in recent years, the space launcher market calls also for cheap micro- and nano-launchers. HREs could help to fill this niche, given their advantages (e.g. high performance, intrinsic safety, throttle-ability, flexibility and low cost), provided that some of the disadvantages are being solved. In this paper, the effect of Forward Facing Step (FFS) and Backward Facing Step (BFS) on the HRE performance (namely regression rate and combustion efficiency) is investigated through test firings. The application of diaphragms, resembling both a FFS and BFS at the same time, and other turbulence and heat exchange enhancing devices in the solid fuel grain have proven to increase both regression rate and combustion efficiency due to the formation of recirculation zones. These zones increase turbulence, mixing as well as heat transfer and, thus, leading to improved performance of the HREs. In order to gain further insight into this phenomenon, an experimental campaign is carried out on a lab-scale HRE using nitrous oxide (N2O) and High-Density Polyethylene (HDPE) as propellants. The cylindrical fuel grain with an external diameter of 130 mm and a length of 117 mm is separated halfway into two different internal diameters. Varying these diameters in the two sides allows creating different FFS and BFS geometries. The focus of the test campaign can be summarized as follows: First, the influence of the step height on the length of the recirculation zone is investigated. Therefore, the fuel grain is probed after the test for indications of the recirculation zone length. Further, the performance impact of BFS and FFS on the HRE is compared under identical conditions. This enables to distinguish the effects for BFS and FFS. Another measurement is the influence of the steps on regression rate and combustion efficiency by weighing the fuel grains before and after the tests and quantifying the thrust respectively. Lastly, the evolution of the steps over time can be assessed by comparing the final geometry of the stepped grain after different burn time lengths. To recapitulate, assessing the test campaign will allow to judge the practically of steps as performance enhancer in HREs.
