description: Despite the increased computational resources, the simulation-based design optimization (SBDO) procedure can be very expensive from a computational viewpoint, especially if high-fidelity solvers are required. Multi-fidelity metamodels have been successfully applied to reduce the computational cost of the SBDO process. In this context, the paper presents the performance assessment of an adaptive multi-fidelity metamodel based on a Gaussian process regression (MF-GPR) for noisy data. The MF-GPR is developed to: (i) manage an arbitrary number of fidelity levels, (ii) deal with objective function evaluations affected by noise, and (iii) improve its fitting accuracy by adaptive sampling. Multi-fidelity is achieved by bridging a low-fidelity metamodel with metamodels of the error between successive fidelity levels. The MF-GPR handles the numerical noise through regression. The adaptive sampling method is based on the maximum prediction uncertainty and includes rules to automatically select the fidelity to sample. The MF-GPR performance are assessed on a set of five analytical benchmark problems affected by noisy objective function evaluations. Since the noise introduces randomness in the evaluation of the objective function, a statistical analysis approach is adopted to assess the performance and the robustness of the MF-GPR. The paper discusses the efficiency and effectiveness of the MF-GPR in globally approximating the objective function and identifying the global minimum. One, two, and three fidelity levels are used. The results of the statistical analysis show that the use of three fidelity levels achieves a more accurate global representation of the noise-free objective function compared to the use of one or two fidelities.

description: COVID-19 has significantly affected universities, forcing many courses to be delivered entirely online. As countries bring the pandemic under control, a potential way to safely resume some face-to-face teaching is the synchronous hybrid classroom, in which physically and remotely attending students are taught simultaneously. This comes with challenges, however, including the risk that remotely attending students perceive a 'gap' between their engagement and that of their physical peers. In this experience report, we describe how an interactive programming course was adapted to hybrid delivery in a way that mitigated this risk. Our solution centred on the use of a professional communication platform - Slack - to equalise participation opportunities and to facilitate peer learning. Furthermore, to mitigate 'Zoom fatigue', we implemented a semi-flipped classroom, covering concepts in videos and using shorter lessons to consolidate them. Finally, we critically reflect on the results of a student survey and our own experiences of implementing the solution.

Spin-lattice relaxation : a probe for molecular geometry and motion in solution
Creators: name: Wong, Kim Fah
Publisher: name: University of British Columbia
Year: 2010

description: The relevant theory and experimental protocol whereby proton spin-lattice relaxation rates (R₁-values) can be used to assign quantitatively the geometry of molecules in solution are described. It is shown that proton R₁-values can provide an accurate measure of solution geometry for rigid molecules which have well dispersed proton n.m.r. spectra, and for which the interproton distances do not span an excessive range. The method is based on identifying the magnitudes of specific, dipole-dipole interproton relaxation contributions (p-values) from measured initial slope proton R₁-values. These p-values can be obtained from either (a) a combination of non-selective, single-selective, double-selective and triple-selective pulse experiments, or (b) selective deuteration. The interproton distances (r) can then be explicitly calculated via the dipole-dipole formalism (ρ ~ r⁻⁶). The interproton distances between the three bicycloheptene ring protons of 1,2,3,4,7,7-hexachloro-6-0-exo-benzoyl-bicyc1o[2.2.1]hept-2-ene (1), determined by method (a), were in excellent agreement with those obtained from computer simulation and Dreiding molecular models. Initial slope, non-selective R₁ values for the protons of 1,2,3,4-tetra-O-trideuterioacetyl-β-D-arabinopyranose (2_), its 5,5-dideuterio-(3) and both isomeric 5-deuterio-derivatives (;4,5_) were determined at 400 MHz. Simple intercomparisons between these data {method (b)} gave ρ-values, from which interproton distances were calculated; these values were in very close agreement with those obtained by neutron diffraction. Method (a) was also used to evaluate the ρ-values for 2; these data were essentially the same as those obtained by (b). The quality control experiments necessary for quantitative conformational analysis are illustrated. These includes (a) a practical definition of an initial slope R₁-value, (b) an evaluation of the extent of dipole-dipole relaxation contributions, and (c) the use of carbon-13 R₁-values to detect the presence or absence of anisotropic motion. It is demonstrated that a combination of non-selective and single-selective relaxation experiments provides quantitative information concerning the validity of the initial slope approximation and the extent to which each proton is relaxed via the dipole-dipole mechanism. A comprehensive evaluation of the applicability and limitation of carbon-13 R₁-values along with deuterium R₁ values as "probes" for molecular motion is also presented. Finally, preliminary surveys of the application of the method to systems having substantial anisotropic motion, systems having complex, second order spectra, and systems with conformational time-averaging are given to place the methodology into chemical contexts which were not a priori designed to be optimized for the approach described herein.

description: Polycrystal microstructures, with their distinct physical, chemical, structural and topological entities, play an important role in determining the effective properties of materials. Particularly for computational studies, the well-known Voronoi tessellation technique is regularly used for obtaining microstructures. Standard Voronoi tessellations, however, exhibit statistics that are generally far removed from those in real microstructures. Nevertheless, such tessellations can be optimized to obtain certain key features and statistics seen in real microstructures. In this work, we develop the open-source software package OptiMic that enables the generation of optimized microstructures for both finite element as well as atomistic simulations. OptiMic allows for both monodispersive grains as well as irregular grains obtained currently via Voronoi tessellations. These initial microstructures can then be optimized to reflect desired statistical features. A key feature of the tool is that it gives the user extensive control on the optimization process via customizable cost functions. The software currently performs tessellations with the Voronoi method and can be easily extended to include other methods like grain-growth, phase-field etc.

We show that a modified canonical transformation applied to the Hubbard model leads to alternative models of the same form, but whose convergence properties with respect to the expansion are more favourable, resulting in a good description of the half-filled ground state even at $0

description: It is a standard exercise in mechanical engineering to infer the external forces and torques on a body from its static shape and known elastic properties. Here we apply this kind of analysis to distorted double-helical DNA in complexes with proteins. We extract the local mean forces and torques acting on each base-pair of bound DNA from high-resolution complex structures. Our method relies on known elastic potentials and a careful choice of coordinates of the well-established rigid base-pair model of DNA. The results are robust with respect to parameter and conformation uncertainty. They reveal the complex nano-mechanical patterns of interaction between proteins and DNA. Being non-trivially and non-locally related to observed DNA conformations, base-pair forces and torques provide a new view on DNA-protein binding that complements structural analysis.

description: The \it{Ambient Logic} (AL) has been proposed for expressing properties of process mobility in the calculus of Mobile Ambients (MA), and as a basis for query languages on semistructured data. We study some basic questions concerning the discriminating power of AL, focusing on the equivalence on processes induced by the logic $(=_L>)$. As underlying calculi besides MA we consider a subcalculus in which an image-finiteness condition holds and that we prove to be Turing complete. Synchronous variants of these calculi are studied as well. In these calculi, we provide two operational characterisations of $_=L$: a coinductive one (as a form of bisimilarity) and an inductive one (based on structual properties of processes). After showing $_=L$ to be stricly finer than barbed congruence, we establish axiomatisations of $_=L$ on the subcalculus of MA (both the asynchronous and the synchronous version), enabling us to relate $_=L$ to structural congruence. We also present some (un)decidability results that are related to the above separation properties for AL: the undecidability of $_=L$ on MA and its decidability on the subcalculus.

description: We report a detailed study of specific heat, electrical resistivity and optical spectroscopy in the superconducting boride LuB12 (Tc = 0.4 K) and compare it to the higher Tc compound ZrB12 (Tc = 6 K). Both compounds have the same structure based on enclosed metallic Lu or Zr ions in oversized boron cages. The infrared reflectivity and ellipsometry in the visible range allow us to extract the optical conductivity from 6 meV to 4 eV in the normal state from 20 to 280 K. By extracting the superconducting properties, phonon density of states and electron-phonon coupling function from these measurements we discuss the important factors governing Tc and explain the difference between the two compounds. The phonon density of states seems to be insignificantly modified by substitution of Zr with Lu. However, the soft vibrations of the metal ions in boron cages, responsible for the relatively high Tc in ZrB12, have almost no contribution to the electron-phonon coupling in LuB12.

description: The ability to recognize the position and order of the floor-level lines that divide adjacent building floors can benefit many applications, for example, urban augmented reality (AR). This work tackles the problem of locating floor-level lines in street-view images, using a supervised deep learning approach. Unfortunately, very little data is available for training such a network $-$ current street-view datasets contain either semantic annotations that lack geometric attributes, or rectified facades without perspective priors. To address this issue, we first compile a new dataset and develop a new data augmentation scheme to synthesize training samples by harassing (i) the rich semantics of existing rectified facades and (ii) perspective priors of buildings in diverse street views. Next, we design FloorLevel-Net, a multi-task learning network that associates explicit features of building facades and implicit floor-level lines, along with a height-attention mechanism to help enforce a vertical ordering of floor-level lines. The generated segmentations are then passed to a second-stage geometry post-processing to exploit self-constrained geometric priors for plausible and consistent reconstruction of floor-level lines. Quantitative and qualitative evaluations conducted on assorted facades in existing datasets and street views from Google demonstrate the effectiveness of our approach. Also, we present context-aware image overlay results and show the potentials of our approach in enriching AR-related applications.

description: We present first results of a pilot project aimed at exploiting the potentiality of ground based adaptive optics imaging in the near infrared to determine the age of stellar clusters in the Galactic Bulge. We have used a combination of high resolution adaptive optics (ESO-VLT NAOS-CONICA) and wide-field (ESO-NTT-SOFI) photometry of the metal rich globular cluster NGC 6440 located towards the inner Bulge, to compute a deep color magnitude diagram from the tip of the Red Giant Branch down to J~22$, two magnitudes below the Main Sequence Turn Off (TO). The magnitude difference between the TO level and the red Horizontal Branch has been used as an age indicator. It is the first time that such a measurement for a bulge globular cluster has been obtained with a ground based telescope. From a direct comparison with 47 Tuc and with a set of theoretical isochrones, we concluded that NGC 6440 is old and likely coeval to 47 Tuc. This result adds a new evidence that the Galactic Bulge is ~2 Gyr younger at most than the pristine, metal poor population of the Galactic Halo.
Electron nuclear double resonance studies of free radicals trapped in x-irradiated single crystals of phenazine, hippuric acid and n-acetylglycine
Creators: name: Singh, Baishnab Charan
Publisher: name: University of British Columbia
Year: 2010

description: The technique of electron nuclear double resonance (ENDOR) spectroscopy has been used to determine the identity and structure of radicals trapped in room temperature X-irradiated single crystals of some biologically important compounds, namely, phenazine, hippuric acid and N-acetylglycine. The ESR spectra of phenazine which had not previously been reported, were too complex to be analyzed. However, the high resolution of ENDOR has made it possible to study all the proton hyperfine interactions in detail. The radicals are formed as a result of the addition of atomic hydrogen to the nitrogen atom of phenazine molecule. The appearance of twice the number of certain ENDOR lines than expected from the crystal symmetry was interpreted by postulating that the radical was stabilized in two different conformations. In hippuric acid (N-Benzoylglycine), the stable N-Benzoylaminomethyl radical formed by room temperature X-irradiation of single crystals has been identified and its structure established by detailed ENDOR studies at 77 K. Besides proton signals, ENDOR transitions arising from the hyperfine and quadrupole interactions of the ¹⁴N nucleus were detected and a detailed analysis is presented. The assignment of exchangeable protons has been accomplished by use of partially deuterated crystals. The radical is most likely formed from oxidised hippuric acid by deprotonation and subsequent decarboxylation. Electronic and molecular structure of the stable radical produced by room temperature X-irradiation of single crystals of N-acetylglycine has been reinvestigated by detailed ESR and ENDOR studies. The results indicate that the radical structure and the nature of the wavefunction of the unpaired electron are significantly different from those reported in a previous 'negative' ENDOR study. In agreement with earlier ESR and ENDOR studies, it is found that the stable radical at room temperature is CH₃CONHCHCOOH. ENDOR lines due to the α-proton, three equivalent methyl protons and six exchangeable protons have been identified and the hyperfine tensors determined. According to the findings, the radical exists in four slightly different conformations. Isotopic substitution with ¹⁵N and deuteration of the exchangeable protons were helpful in the analysis of the complex ESR and ENDOR spectra. It has been conclusively shown that the multiplet structure in the ESR spectrum of irradiated N- acetylglycine arises from the interaction of the unpaired electron with protons of the methyl group and the ¹⁴N nucleus. It has been also demonstrated that the radical concentration in the crystal has to be very carefully controlled for the success of an ENDOR investigation. In order to confirm the radical identification INDO-MO calculations have been performed on all the radicals reported here. Excellent agreement has been obtained between the observed spin densities and those computed by the INDO-MO calculations.
On Pseudo Algebraically Closed Extensions of Fields

description: The notion of `Pseudo Algebraically Closed (PAC) extensions' is a generalization of the classical notion of PAC fields. It was originally motivated by Hilbert's tenth problem, and recently had new applications. In this work we develop a basic machinery to study PAC extensions. This machinery is based on a generalization of embedding problems to field extensions. The main goal is to prove that the Galois closure of any proper separable algebraic PAC extension is its separable closure. This vastly generalizes earlier works of Jarden-Razon, Jarden, and Jarden and the author. This also leads to a classification of all finite PAC extensions which in turn proves the `bottom conjecture' for finitely generated infinite fields. The secondary goal of this work is to unify proofs of known results about PAC extensions and to establish new basic properties of PAC extensions, e.g.\ transitiveness of PAC extensions.

Year: 2018

description: The construction and interpretation of graphs is one oft he most important skills that students learn in physics lessons. Yet there are a lot of misconceptions concerning the creation and analysis of kinematics graphs. In the course of this diploma thesis, the digital, web-based learning game Graph Sketching (available at www.graphsketching.at) was developed. During gameplay, students need to draw motion diagrams in order to move a character through different levels. A study in an NMS shows that the learning game has a motivating effect on students who are otherwise rather difficult to inspire. Especially younger pupils in the second grade enjoy playing the game. After the intervention with Graph Sketching, the students participating in the study achieve the same number of points on four selected testitems, as other studies report for pupils attending an introductory kinematics lesson. Also, the frequently occurring misconception Slope / Height Confusion is detected less often after playing the game. On the other hand, there is no apparent reduction of the misconception Graph as Picture Error.
description: Das Konstruieren und Interpretieren von Graphen zählt zu den wichtigsten Fähigkeiten, die Schülerinnen und Schüler im Physikunterricht lernen. Dennoch treten bei dem Zeichnen und Analysieren von Kinematik-Graphen oft Fehlvorstellungen auf. Im Zuge dieser Diplomarbeit wurde auf der Grundlage von fachdidaktischen und lerntheoretischen Überlegungen ein digitales, webbasiertes Lernspiel mit dem Titel Graph Sketching (aufrufbar unter www.graphsketching.at) zum Anfertigen und Interpretieren von Bewegungsdiagrammen entwickelt. Eine in einer NMS durchgeführte Studie mit einem Prä-, Post- und Follow Up-Test Design zeigt, dass das Lernspiel selbst auf sonst eher schwer zu begeisternde Schülerinnen und Schüler motivierend wirkt, Kinder mit einer guten Einstellung zum Physikunterricht aber mehr Spaß beim Spielen haben. Bezogen auf die Schulstufe wird das Serious Game vor allem in den zweiten Klassen positiv bewertet. Nach der Intervention mit Graph Sketching erreichen die an der Studie teilnehmenden Schülerinnen und Schüler vergleichbar viele Punkte auf vier ausgewählte Beispiele zu Bewegungsdiagrammen, wie laut Literaturwerten nach einem einführenden Kinematikunterricht erwartet werden können. Die häufig auftretende Schülervorstellung Slope / Height Confusion wird dabei nach dem Spielen weniger oft festgestellt als davor. Bezogen auf die Fehlvorstellung Graph as Picture Error kann dagegen keine Verringerung beobachtet werden.

description: The COVID-19 pandemic triggered a wave of novel scientific literature that is impossible to inspect and study in a reasonable time frame manually. Current machine learning methods offer to project such body of literature into the vector space, where similar documents are located close to each other, offering an insightful exploration of scientific papers and other knowledge sources associated with COVID-19. However, to start searching, such texts need to be appropriately annotated, which is seldom the case due to the lack of human resources. In our system, the current body of COVID-19-related literature is annotated using unsupervised keyphrase extraction, facilitating the initial queries to the latent space containing the learned document embeddings (low-dimensional representations). The solution is accessible through a web server capable of interactive search, term ranking, and exploration of potentially interesting literature. We demonstrate the usefulness of the approach via case studies from the medicinal chemistry domain.

description: Let $(X,d)$ be a compact metric space, $f:X \mapsto X$ be a continuous map with the specification property, and $φ: X \mapsto \IR$ be a continuous function. We prove a variational principle for topological pressure (in the sense of Pesin and Pitskel) for non-compact sets of the form \[ \{x \in X : \lim_{n \ra \infty} \frac{1}{n} \sum_{i = 0}^{n-1} φ(f^i (x)) = α\}. \] Analogous results were previously known for topological entropy. As an application, we prove multifractal analysis results for the entropy spectrum of a suspension flow over a continuous map with specification and the dimension spectrum of certain non-uniformly expanding interval maps.

Ethics in the banking industry: identifying the industrial and external factors influencing behaviours in the industry

Subjects: Financial institutions (incl. banking)

description: Finance and economy, more importantly banking as a branch within finance, have a vast influence in our daily lives. History has shown that the decisions made by these institutions that were set up on one hand to provide security around the population’s wealth, and on the other to help manage and control the flow of money; can affect positively or negatively every member of society. Recently, populations around the world have suffered due to a crisis that sparked from the banking sector. This crisis has led the ethical culture in the industry as well as the role of governments and regulators to be questioned. This thesis presents an original perspective of ethics in the banking industry in the United Kingdom by analysing factors in the banking system influencing banker’s behaviour and evaluating the codes of conducts and codes of ethics of banking institutions. Using an OLS-moderated regression method, results show that certain aspects of the industry paradigm are not conducive to the preservation of ethics. It has been found that the long-term orientation, strategic aggressiveness, and competitive intensity of a bank can influence employees’ ethical behaviour. Finally, the evaluation of the codes of ethics and codes of conduct in the industry has shown important gap in the banks’ policies particularly with regards to the influence of banks strategic aggressiveness and competitive intensity on employee behaviour. This work has deep implications for further studies of ethics in the banking industry and could spark a new wave of research that will seek to formulate a proven framework to manage ethics in the industry.

description: We present synthetic OH Zeeman splitting measurements of a super-Alfvenic model of molecular clouds. We select dense cores from synthetic 13CO maps computed from the largest simulation to date of supersonic and super-Alfvenic turbulence. The synthetic Zeeman splitting measurements in the cores yield a relation between the magnetic field strength, B, and the column density, N, in good agreement with the observations. The large scatter in B at a fixed value of N is partly due to intrinsic variations in the magnetic field strength from core to core. We also compute the relative mass-to-flux ratio between the center of the cores and their envelopes, ${\cal R}_μ$, and show that super-Alfvenic turbulence produces a significant scatter also in ${\cal R}_μ$, including negative values (field reversal between core center and envelope). We find ${\cal R}_μ<1$ for 70% of the cores, and ${\cal R}_μ<0$ for 12%. Of the cores with $|B_{\rm LOS}|>10$ \muG, 81% have ${\cal R}_μ<1$. These predictions of the super-Alfvenic model are in stark contrast to the ambipolar drift model of core formation, where only ${\cal R}_μ>1$ is allowed.

Kriegsmetaphorik in der spanischen Fußballberichterstattung
Creators: name: Schneider, Veronika
Year: 2018

description: Die Metapher ist eine Stilfigur, die in allen Teilbereichen des Lebens präsent ist und dabei eine große Auswirkung darauf hat, wie wir die Welt wahrnehmen. Sie hilft uns dabei, Phänomene durch Begriffe anderer Herkunftsfelder darzustellen, weswegen auf sie gerne in Fußballchroniken zurückgegriffen wird. Die Verfasser_innen dieser Spielzusammenfassungen stehen vor der Herausforderung, das Spiel, das zu einem bereits bekannten Ergebnis geführt hat, auf eine spannende Art darzustellen. Da sie in diesen Berichten eine subjektive Note gewünscht ist, ist die Metapher eine gute Methode, um emotional aufgeladene Bilder bei den Leser_innen auszulösen.
Die Analyse der metaphorischen gebrauchten Wörter kriegerischer Lexik in den spanischen Fußballchroniken von sieben Zeitungen (As, Marca, Sport, El Mundo Deportivo, ABC, La Vanguardia, El País) hat ergeben, dass diese einen bedeutenden Anteil des angewandten Sprachmaterials stellen. Dieser fällt in den Sportzeitungen aus Barcelona (Sport, El Mundo Deportivo) höher aus, da diese das Spielgeschehen auf dem Platz ausführlich beschreiben und sich dafür toter Metaphern aus dem taktischen Bereich bedienen. Im Gegensatz dazu fassen die Madrider Sportzeitungen das Spiel auf kürzerem Raum durch Bilder, die oft aus dem kriegerischen Bereich stammen, zusammen. Ähnliches trifft auf die allgemeinen Tageszeitungen (ABC, La Vanguardia) zu, deren Artikel länger sind und auch außersportliche Anspielungen inkludieren.
Innerhalb dieser ist die bedeutendste Kategorie die konzeptuelle Metapher FUSSBALL IST KRIEG, die neben einem großen Grat an Lexikalisierung militärischer Termini auch innovativ in Begriffen benutzt wird, die das Fußballspiel mit einer Schlacht gleichsetzen. Diese Schlacht solle durch einen Kampf auf Leben und Tod ausgetragen werden, wobei Schüsse als Waffen dienten, um dem Gegner Schaden zuzufügen, ihn zu töten und das eigenen Überleben zu sichern.
Der intensive Gebrauch der Kriegslexik in der Fußballberichterstattung prägt unser Bild auf den Sport, den wir mit dem kämpferischen Element verbinden, anstatt den Spaß hervorzuheben. Aufgrund der großen Parallelen zwischen Fußball und Krieg ist es allerdings schwierig, die taktischen Begriffe durch weniger brutale zu ersetzen. Angesetzt jedoch werden könnte bei den innovativen Bildern, denen sich die Journalist_innen bedienen, um das Geschehen anschaulich zu beschreiben und die von Verweisen auf Krieg, Zerstörung und Tod gefüllt sind, anstatt anderen Bildspendefeldern Raum zu geben.

description: The graphene-inspired fermion actions recently proposed by Creutz and Borici have sparked interest in the use of non-orthogonal lattices in lattice QCD. These fermion actions have the desired chiral symmetry and have the minimal doubling required by the Nielsen-Ninomiya no-go theorem. However, due to the lack of discrete symmetries, radiative corrections in the gauged lattice theory will lead to the generation of unwanted relevant and marginal operators. Other similarly motivated non-orthogonal fermion actions avoid these unwanted operators, but introduce incorrect continuum behavior or excessive fermion doubling. A delicate balance of symmetry is required for chiral symmetry, minimal doubling, and no relevant operators, and to date, no non-orthogonal lattice action has accomplished this balance.

description: Cool weakly ionized gaseous rotating disk form the basis for many models in astrophysics objects. Instabilities against perturbations in such disks play an important role in the theory of the formation of stars and planets. Traditionally, axisymmetric magnetohydrodynamic (MHD) and recently Hall-MHD instabilities have been thoroughly studied as providers of an efficient mechanism for radial transfer of angular momentum, and of density radial stratification. In the current work, the Hall instability against axisymmetric perturbations in incompressible rotating fluid in external poloidal and toroidal magnetic field is considered.

description:
Pigment-dispersing factors (PDFs) are neuropeptides that play key roles in controlling the circadian rhythms in various insects, whereas their function remains elusive in other protostomes including tardigrades (water bears). Here we show that the three PDFs of the tardigrade Hypsibius exemplaris are co-localized in two pairs of inner lobe cells in the brain, whereas only one PDF occurs in four additional cerebral and two extracerebral cells. The axons of the inner lobe cells pass through the contralateral brain hemisphere, descend to the ventral nerve cord and terminate in two pairs of potential release sites in the posteriormost trunk ganglion. Using in vitro assays, we demonstrate that all three PDFs and their deorphanized receptor (PDFR) are functional. Widespread localization of PDFR suggests that tardigrade PDFs may act as multifunctional hormones and neuromodulators that control major functions including light detection, neural processing, locomotion, feeding, digestion, osmoregulation, growth, embryonic development and oogenesis/reproduction.

This paper describes an experimental and numerical optimization procedure for off-line extraction of parameters for unsymmetrical, single-phase induction machines with capacitor-start operation.
This paper describes an experimental and numerical optimization procedure for off-line extraction of parameters for unsymmetrical, single-phase induction machines with capacitor-start operation. In addition to permitting asymmetry between phase winding parameters, the approach requires only average and rms measurements as inputs; electrical phase angle measurements are not required. The method is validated on an experimental motor with transient and steady-state simulations, using fitted parameters obtained using the proposed approach.
About the Chemical Evolution of dSphs (and the peculiar Globular Cluster Omega Cen)

description: We present three dimensional hydrodynamical simulations aimed at studying the dynamical and chemical evolution of the interstellar medium (ISM) in isolated dwarf spheroidal galaxies (dSphs). This evolution is driven by the explosion of Type II and Type Ia supernovae, whose different contribution on both the dynamics and chemical enrichment is taken into account. Radiative losses are effective in radiating away the huge amount of energy released by SNe explosions, and the dSph is able to retain most of the gas allowing a long period (>2-3 Gyr) of star formation, as usually observed in this kind of galaxies. We are able to reproduce the stellar metallicity distribution function (MDF) as well as the peculiar chemical properties of strongly O-depleted stars observed in several dSphs. The model also naturally predicts two different stellar populations, with an anti-correlation between [Fe/H] and velocity dispersion, similarly to what observed in the Sculptor and Fornax dSphs. These results derive from the inhomogeneous pollution of the SNe Ia, a distinctive characteristic of our model. We also applied the model to the peculiar globular cluster (GC) Omega Cen in the hypothesis that it is the remnant of a formerly larger stellar system, possibly a dSph.

description: The master thesis analysis the works of german writer Ernst Jünger between 1929 and 1942 within the context of covert spelling as a form of intellectual resistance against the Nazi regime.
description: Die folgende Masterarbeit beleuchtet Ernst Jüngers erzählerisches Werk zur Zeit des Nationalsozialismus vor dem Hintergrund der geistigen Oppositionshaltung des Autors. Jünger erarbeitet sich zwischen 1933 und 1945 ein poetisches Programm, das vor allem der Selbstvergewisserung und Selbstbehauptung in Zeiten des moralischen Niedergangs, der Tyrannei und des Schreckens dienen soll. Anhand der beiden Fassungen des Abenteuerlichen Herzen (1929/1938) wird die Entwicklung und literarische Inszenierung dieser Haltung des intellektuellen Widerstands deutlich gemacht. Dabei wird insbesondere auf die von Jünger entwickelten, spezifischen Formen der ‚verdeckten Schreibweise’ eingegangen, die ein ungeahntes regimekritisches Potential aufweisen. Mit ihnen entlarvt sich der Schriftsteller Ernst Jünger als Idealbild des von ihm entworfenen Typus des ‚Waldgängers’.

description: A set of key properties for an ideal dissipation scheme in gyrokinetic simulations is proposed, and implementation of a model collision operator satisfying these properties is described. This operator is based on the exact linearized test-particle collision operator, with approximations to the field-particle terms that preserve conservation laws and an H-Theorem. It includes energy diffusion, pitch-angle scattering, and finite Larmor radius effects corresponding to classical (real-space) diffusion. The numerical implementation in the continuum gyrokinetic code GS2 is fully implicit and guarantees exact satisfaction of conservation properties. Numerical results are presented showing that the correct physics is captured over the entire range of collisionalities, from the collisionless to the strongly collisional regimes, without recourse to artificial dissipation.

description: On edge devices, data scarcity occurs as a common problem where transfer learning serves as a widely-suggested remedy. Nevertheless, transfer learning imposes a heavy computation burden to resource-constrained edge devices. Existing task allocation works usually assume all submitted tasks are equally important, leading to inefficient resource allocation at a task level when directly applied in Multi-task Transfer Learning (MTL). To address these issues, we first reveal that it is crucial to measure the impact of tasks on overall decision performance improvement and quantify \emph{task importance}. We then show that task allocation with task importance for MTL (TATIM) is a variant of the NP-complete Knapsack problem, where the complicated computation to solve this problem needs to be conducted repeatedly under varying contexts. To solve TATIM with high computational efficiency, we propose a Data-driven Cooperative Task Allocation (DCTA) approach. Finally, we evaluate the performance of DCTA by not only a trace-driven simulation, but also a new comprehensive real-world AIOps case study that bridges model and practice via a new architecture and main components design within the AIOps system. Extensive experiments show that our DCTA reduces 3.24 times of processing time, and saves 48.4\% energy consumption compared with the state-of-the-art when solving TATIM.
