description: As more and more autonomous vehicles (AVs) are being deployed on public roads, designing socially compatible behaviors for them is becoming increasingly important. In order to generate safe and efficient actions, AVs need to not only predict the future behaviors of other traffic participants, but also be aware of the uncertainties associated with such behavior prediction. In this paper, we propose an uncertain-aware integrated prediction and planning (UAPP) framework. It allows the AVs to infer the characteristics of other road users online and generate behaviors optimizing not only their own rewards, but also their courtesy to others, and their confidence regarding the prediction uncertainties. We first propose the definitions for courtesy and confidence. Based on that, their influences on the behaviors of AVs in interactive driving scenarios are explored. Moreover, we evaluate the proposed algorithm on naturalistic human driving data by comparing the generated behavior against ground truth. Results show that the online inference can significantly improve the human-likeness of the generated behaviors. Furthermore, we find that human drivers show great courtesy to others, even for those without right-of-way. We also find that such driving preferences vary significantly in different cultures.

description: Da die Lesung bisher wenig Aufmerksamkeit seitens der Literaturwissenschaft erhalten hat, ist es notwendig, den Begriff in der vorliegenden Arbeit zu definieren. Dies wird erreicht, indem die verschiedenen Aspekte, die zum Ablauf einer Lesung gehören, beleuchtet wehrden. Die heutige Lesungspraxis ist eng verbunden mit alten Traditionen des Geschichtenerzählens und dem lauten Lesen in Gesellschaft. Heute hat die Lesung eine wichtige ökonomische Bedeutung für den Literatur- und Kulturbetrieb indem sie als werbetechnisches Mittel für Autoren, Bücher und Verlage fungiert. Die zentrale Fragestellung dieser Arbeit beschäftigt sich mit der Lesung und ihrer Rezeption, welche sich grundlegend von der der stillen Lektüre unterscheidet. Es werden die unterschiedlichen Formen der Interaktion zwischen Vortragendem und Publikum aufgezeigt, welche beeinflusst wird von den räumlichen Gegebenheiten, der körperlichen Präsenz beider Seiten und den stimmlichen und körpersprachlichen Ausdrucksmöglichkeiten des Vorlesers. Ebenso werden die Motivationen, die zum Besuch einer Lesung führen, analysiert.

description: We present two classical algorithms for the simulation of universal quantum circuits on $n$ qubits constructed from $c$ instances of Clifford gates and $t$ arbitrary-angle $Z$-rotation gates such as $T$ gates. Our algorithms complement each other by performing best in different parameter regimes. The $\tt{Estimate}$ algorithm produces an additive precision estimate of the Born rule probability of a chosen measurement outcome with the only source of run-time inefficiency being a linear dependence on the stabilizer extent (which scales like $\approx 1.17^t$ for $T$ gates). Our algorithm is state-of-the-art for this task: as an example, in approximately $13$ hours (on a standard desktop computer), we estimated the Born rule probability to within an additive error of $0.03$, for a $50$-qubit, $60$ non-Clifford gate quantum circuit with more than $2000$ Clifford gates. Our second algorithm, $\tt{Compute}$, calculates the probability of a chosen measurement outcome to machine precision with run-time $O(2^{t-r} t)$ where $r$ is an efficiently computable, circuit-specific quantity. With high probability, $r$ is very close to $\min \{t, n-w\}$ for random circuits with many Clifford gates, where $w$ is the number of measured qubits. $\tt{Compute}$ can be effective in surprisingly challenging parameter regimes, e.g., we can randomly sample Clifford+$T$ circuits with $n=55$, $w=5$, $c=10^5$ and $t=80$ $T$ gates, and then compute the Born rule probability with a run-time consistently less than $10$ minutes using a single core of a standard desktop computer. We provide a C+Python implementation of our algorithms and benchmark them using random circuits, the hidden shift algorithm and the quantum approximate optimization algorithm (QAOA).

We calculate the relative rank of the semigroup $OP(X,Y)$ of all orientation-preserving transformations on $X$ with restricted range $Y$ modulo the semigroup $O(X,Y)$ of all order-preserving transformations on $X$ with restricted range $Y$. For $Y = X$, we characterize the relative generating sets of minimal size.

description: Cycle sets are known to give non-degenerate unitary solutions of the Yang--Baxter equation and linear cycle sets are enriched versions of these algebraic systems. The paper explores the recently developed cohomology and extension theory for linear cycle sets. We derive a four term exact sequence relating 1-cocycles, second cohomology and certain groups of automorphisms arising from central extensions of linear cycle sets. This is an analogue of a similar exact sequence for group extensions known due to Wells. We also compare the exact sequence for linear cycle sets with that for their underlying abelian groups via the forgetful functor and discuss generalities on dynamical 2-cocycles.

description: Die Arbeit beschäftigt sich mit der Themenstellung, inwieweit der Roman The Road to Wellville (1993) des amerikanischen Autors T.C. Boyle als postmoderne Reproduktion von Thomas Manns Der Zauberberg (1924) gesehen werden kann. Um diese Frage zu erörtern, werden einleitend Leben und Werk der Autoren T.C. Boyle und Thomas Mann vorgestellt. In einem theoretischen Teil werden Der Zauberberg und The Road to Wellville in ihrer Entstehungsgeschichte und Struktur untersucht und in der Moderne beziehungsweise Postmoderne literaturwissenschaftlich eingeordnet. Der Hauptteil der Arbeit beschäftigt sich mit dem genetischen Vergleich der beiden Romane. Dabei werden systematisch intertextuelle Verweise in The Road to Wellville auf den Zauberberg erforscht. Im Wesentlichen werden dabei strukturelle Elemente des Sanatorium-Settings, Gestaltung und Konstellation der Hauptfiguren, sowie die Verhandlung politischer und wirtschaftlicher Entwicklungen in ihrem zeitgeschichtlichen Kontext herausgearbeitet, analysiert und interpretiert. Die Arbeit zeigt, wie Der Zauberberg als Subtext die Bedeutung und Wirkung von The Road to Wellville erweitert, und wie durch diese Beziehung eine literarische Kommunikation eröffnet wird, die gesellschaftliche und zeitgeschichtliche Phänomene zu Beginn und gegen Ende des 20. Jahrhunderts verhandelt.

description: Topological phases of the famous Altland-Zirnbauer (AZ) tenfold classes are defined on the equilibrium ground states. Whether such equilibrium topological phases have universal correspondence to far-from-equilibrium quantum dynamics is a fundamental issue of both theoretical and experimental importance. Here we uncover the universal topological quench dynamics linking to the equilibrium topological phases for the complete AZ tenfold classes, with a general framework being established. We show a fundamental result that a $d$-dimensional topological phase of the tenfold class, with an integer invariant or $\mathbb{Z}_{2}$ index defined on high symmetry momenta, is generically characterized by topology reduced to the highest-order band-inversion surfaces located at arbitrary discrete momenta of Brillouin zone. Such dimension-reduced topology is further captured by universal topological patterns emerging in far-from-equilibrium quantum dynamics by quenching the system from trivial phase to the topological regime, rendering the dynamical hallmark of the equilibrium topological phase. This work establishes a universal dynamical characterization for the complete AZ symmetry classes of topological phases, which has broad applications in theory and experiment.

description: Strongly interacting electrons in solids are generically described by Hubbardtype models, and the impact of solar light can be modeled by an additional time-dependence. This yields a finite dimensional system of ordinary differential equations (ODE)s of Schrödinger type, which can be solved numerically by exponential time integrators of Magnus type. The efficiency may be enhanced by combining these with operator splittings. We will discuss several different approaches of employing exponential-based methods in conjunction with an adaptive Lanczos method for the evaluation of matrix exponentials and compare their accuracy and efficiency. For each integrator, we use defect-based local error estimators to enable adaptive time-stepping. This serves to reliably control the approximation error and reduce the computational effort

DIFFUSION TESTING AND DEVELOPMENT OF A WATER FILTRATION SYSTEM USING BIODEGRADABLE CROSSLINKED POLYMERIC FILMS
Creators: name: Brown, Karlena L.
Publisher: name: American University
Year: 2023

description: In this particular study, several polymeric films composed of polyvinyl alcohol and ionic liquid modified clays were crosslinked in the presence of glutaraldehyde to develop a water filtration system. The goal was to create a functional, biodegradable, environment friendly filtration system in which water contaminants such as dye could easily be removed from a potential water source. Throughout this study, several tests were conducted in order to fully understand how each clay modifier would affect the swelling characteristics of the film, the crystalline and melting characteristics of the film, and finally the diffusion of ions or dye through the film. It was concluded that these components were vital when attempting to understand and develop a potential water filtration system because each modification maintained differing diffusion trends regarding dye removal. Furthermore, by removing contaminates such as dye from a polluted water source, this study exemplified how other hazardous aromatic hydrocarbons could possibly be removed on a grander scale. All analyses regarding both clay and film modifications were completed using DSC, ISE, X - ray diffraction, and UV - Vis.

description: Based on direct numerical simulations with point-like inertial particles, with Stokes numbers, $\textrm{St}=0, 0.5$, $3$, and $6$, transported by homogeneous and isotropic turbulent flows, we present in this letter for the first time evidence for the existence of Markov property in Lagrangian turbulence. We show that the Markov property is valid for a finite step size larger than a Stokes number-dependent Einstein-Markov coherence time scale. This enables the description of multi-scale statistics of Lagrangian particles by Fokker-Planck equations, which can be embedded in an interdisciplinary approach linking the statistical description of turbulence with fluctuation theorems of non-equilibrium stochastic thermodynamics and local flow structures. The formalism allows estimation of the stochastic thermodynamics entropy exchange associated with the particles' Lagrangian trajectories. Entropy consuming trajectories of the particles are related to specific evolution of velocity increments through scales and may be seen as intermittent structures. Statistical features of Lagrangian paths and entropy values are thus fixed by the fluctuation theorems.

title: Desillusionierung und Kriegsernüchterung in Edlef Köppens "Heeresbericht", Erich Maria Remarques "Im Westen nichts Neues" und Ludwig Renns "Krieg"
Creators: name: Stadler, Martina
Year: 2013

description: Die vorliegende Diplomarbeit befasst sich mit drei Romanen aus dem Bereich der Kriegsliteratur des Ersten Weltkrieges. Es handelt sich dabei um Edlef Köppens "Heeresbericht", Erich Maria Remarques "Im Westen nichts Neues" und Ludwig Renns "Krieg". Die Werke zeichnen sich durch eine kriegskritische Haltung aus. Diese Art von Literatur versucht nicht zuletzt den Leser zum Kriegsgegner zu machen. Deshalb ist das Ziel dieser Arbeit zu demonstrieren, auf welche Weise die Vermittlung von Desillusionierung und Kriegsernüchterung in den Romanen erfolgt. Auffallend hierbei sind die zahlreichen thematischen Ähnlichkeiten der Romane, deren Bedeutung es zu erörtern gilt. Darüber hinaus befasst sich die Arbeit mit der literarischen Umsetzung der Themen. Das heißt, die sprachliche, stilistische und strukturelle Gestaltung ist ebenfalls Gegenstand der Besprechung. Die Analyse der Romane erfolgt im direkten Vergleich, im Zuge dessen sich Gemeinsamkeiten und Unterschiede deutlich abzeichnen.

description: With the worldwide industrialization of black soldier fly (BSF) production, it is necessary to better understand how the rearing scale and larvae density influence the performance of larvae and the quality of the final product. In this study, a factorial experiment was conducted to test the effect of rearing scale and density on the growth and composition of the BSF larvae. The larvae were grown in four different scales (box sizes), keeping the area and feed provided to each larva constant and in two different densities. The results reveal significant differences in the larval growth depending on the scale and density, which could be attributed to the higher temperatures achieved in the bigger scales with a temperature difference of more than 5 °C between the smallest and the biggest scale. Both the scale and the density influenced the composition of the larvae. The crude protein levels were higher on the smallest scale, and the lower density (ranging from 32.5% to 36.5%), and crude fat concentrations were the opposite (ranging from 31.7% to 20.1%). The density also influenced the concentrations of S, Mg, K, P, Fe, Zn, Cu, Al, B, and Co, in addition to the analyzed free amino acids PPS, ALA, CIT, and ANS. Furthermore, the rearing scale influenced the concentration of S, Zn, Cu, and Mo. The results provide further insight into the optimization of BSF production processes and the transfer of lab-scale results into big-scale production.

description: Progress on the study of synchronisation in quantum systems has been largely driven by specific examples which resulted in several examples of frequency entrainment as well as mutual synchronisation. Here we study quantum synchronisation by utilising Liouville space perturbation theory. We begin by clarifying the role of centers, symmetries and oscillating coherences in the context of quantum synchronisation. We then analyse the eigenspectrum of the Liouville superoperator generating the dynamics of the quantum system and determine the conditions under which synchronisation arises. We apply our framework to derive a powerful relationship between energy conservation, degeneracies and synchronisation in quantum systems. Finally, we demonstrate our approach by analysing two mutually coupled thermal machines and the close relationship between synchronisation and thermodynamic quantities.

Here we present Chandra X-ray Observatory observations of eleven dwarf galaxies that were chosen as AGN candidates using Wide-field Infrared Survey Explorer (WISE) mid-infrared (mid-IR) color-color selection. Hubble Space Telescope images are also presented for ten of the galaxies. Based on Sloan Digital Sky Survey spectroscopy, six galaxies in our sample have optical evidence for hosting AGNs and five are classified as star-forming. We detect X-ray point sources with luminosities above that expected from X-ray binaries in the nuclei of five of the six galaxies with optical evidence of AGNs. However, the X-ray emission from these AGNs is generally much lower than expected based on AGN scaling relations with infrared and optical tracers. We do not find compelling evidence for AGNs in the five optically-selected star-forming galaxies despite having red mid-IR colors. Only two are detected in X-rays and their properties are consistent with stellar-mass X-ray binaries. Based on this multiwavelength study, we conclude that two-color mid-IR AGN diagnostics at the resolution of WISE cannot be used to reliably select AGNs in optically-star-forming dwarf galaxies. Future observations in the infrared with the James Webb Space Telescope offer a promising path forward.

description: An increase in the demand for clean and sustainable energy storage with a high power density, along with a long cyclic life time has made supercapacitors an emerging energy storage device. However, one of the main challenges of today's world is to develop energy storage devices which are environmental friendly, cost effective, and which posses an excellent storage capacity. Therefore, this thesis presents the experimental results of utilizing nickel nanoparticle impregnated carbonized wood as a potential electrode material for supercapacitor applications. The electrode was synthesized by carbonizing the nickel nitrate impregnated wood at 900oC for an hour. The concentration of nickel nanoparticles in the carbonized wood was varied by changing the concentration of nickel nitrate solution. The surface morphology and the structure of the electrodes as prepared were studied by using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and X-ray Photoelectron Spectroscopy (XPS). Electrochemical characterization such as Cyclic Voltammetry showed the presence of peaks indicating a psuedocapacitive behavior of the electrode. The Galvanostatic charge-discharge measurements showed nonlinear charge-discharge curves with changes in the slope. From the electrochemical measurements, it is observed that the electrode material exhibited a specific capacitance of 3616 F/g and a power density of 30 kW/kg along with an excellent capacitance retention of greater than 80% after 6000 charge-discharge cycles. These results indicate that the nickel nanoparticle impregnated carbonized wood could be one of the potential electrode materials for supercapacitor applications.

description: Neutron stars can be destroyed by black holes at their center accreting material and eventually swallowing the entire star. Here we note that the accretion model adopted in the literature, based on Bondi accretion or variations thereof, is inadequate for small black holes -- black holes whose Schwarzschild radius is comparable to, or smaller than, the neutron's de Broglie wavelength. In this case, quantum mechanical aspects of the accretion process cannot be neglected, and give rise to a completely different accretion rate. We show that for the case of black holes seeded by the collapse of bosonic dark matter, this is the case for electroweak-scale dark matter particles. In the case of fermionic dark matter, typically the black holes that would form at the center of a neutron star are more massive, unless the dark matter particle mass is very large, larger than about 10$^{10}$ GeV. We calculate the lifetime of neutron stars harboring a ``small'' black hole, and find that black holes lighter than $\sim 10^{11}$ kg quickly evaporate, leaving no trace. More massive black holes destroy neutron stars via quantum accretion on time-scales much shorter than the age of observed neutron stars. We find that the range where seed black holes inside neutron stars are massive enough that they do not quickly evaporate away, but not so massive that a fluid accretion picture is warranted is limited to between $\sim10^{11}$ and $10^{12}$ kg, but our results are key to accurately determine the actual critical black hole mass corresponding to the onset of neutron star destruction

description: A novel mm-wave microstrip-fed patch antenna with broad bandwidth and wide angular coverage suitable for integration in planar arrays is designed, analyzed and verified by measurements. The antenna provides a bandwidth of 13.1% between 34.1 GHz and 38.9 GHz, which is achieved by a slotted multiple resonances microstrip patch and a matching circuit in microstrip technology. The antenna is built on RO3003 substrate with top and ground layers, which is low cost compared to other techniques. For simple integration with microstrip and frontend circuits, the feeding happens in the top layer with a microstrip coupling gap feed. The wide half power beamwidth is achieved by suitably designed parasitic patches for the first resonant mode. The second resonant mode has a wide half power beamwidth by default. The half power beamwidth is between 100° and 125° within the matched bandwidth, which is a very good value for a microstrip patch antenna radiating over a ground plane. The measured input impedance and radiation characteristic show very good agreement with simulation results.

description: Despite the fact that scrap metal recycling is a profitable industry, there are limitations to the methods currently being used to sort the scrap. Particle sizes below 2.5~cm present the biggest challenge for current sorting technologies. This limitation creates a need for an improved technique to sort scrap metal. Electrodynamic Sorting, which uses stationary magnets with a time-varying magnetic field, is investigated as a tool that can overcome these limitations within the scope of this paper. The objective of this thesis is to provide insight into the properties governing Electrodynamic Sorting.  This thesis explores the relationship between power and frequency for two different kinds of magnets. The end results show that the magnets, which are made of different materials, both had a parabolic fit when power was plotted against current as well as when power was plotted against frequency. Another contribution from this work is a comparison of force predictions determined mathematically and the force measured experimentally. With current held constant while frequency was varied, the ejection force on a particle placed within a gapped toroid magnet was measured and plotted against a mathematically predicted plot. The results of the measurements agree with the predicted plot for various size, shape, and types of nonferrous materials used. This information allows us to make some inferences about this Electrodynamic Sorting technique and its potential use in industry.

description: The concept of self-mixing antenna arrays is presented and analyzed with respect to its beneficial behavior of large gain over a wide angular range. The large gain is attained by an antenna array with large element spacing, where all array element signals are combined approximately coherently over the entire angular receiving range. This functionality is achieved by the self-mixing principle, where an exact description via an intermediate frequency (IF) array factor is derived. For verification purposes, a 4 x 2 self-mixing array is fabricated and measured in the frequency range from 34 GHz to 39 GHz. A multiple-resonances millimeter-wave microstrip patch antenna has been especially developed to achieve large bandwidth and a wide angular receiving range. The broad beamwidth is achieved by two parasitic patches and suitable radiation characteristics of the resonant modes. The self-mixing of the receive signal is realized at each antenna element by a Schottky diode with an optimized operating point. The down-converted array element signals are then combined and measured at the IF. The receive power is increased significantly over a large angular range as compared to conventional array feeding techniques. The simulation results are verified by measurements, which show very good agreement.

description: The Ordovician age Utica-Point Pleasant (UPP) formation found in eastern Ohio has demonstrated, over the past 7 years through production, to be a significant shale play in the United States. Historical production data show that the play is predominantly gas producing. Conversely, and although relatively minimal production compared to gas, oil production zones do exist, and trend from the northwestern towards the central part of Ohio. In recent years, the UPP formation has received substantial industry attention because of its projected production potential. However, due to limited exploration outside the gas window and little understanding of the maturity levels within the formation, the production potential for unconventional oil remains uncertain in the UPP play. Using a newly developed pyrolysis method, Incremental S1 (IS1), on a suite of samples from four wells located in zones of low maturity, oil maturity, and condensate maturity, oil quality can be predicted. To complement and validate the newly developed IS1 method for determining oil quality, selected UPP samples were also sent to GeoMark Research to perform oil extraction and gas chromatography analysis. Combining GC extraction and IS1 results, petroleum quality within the Utica-Point Pleasant formation of Ohio can be better resolved, facilitating the potential for production within the play.
