description: Electric vehicles will play a key role in decarbonizing the transport sector due to their higher efficiency compared to alternative technologies. With an increasing market ramp-up of electric vehicles the energy demand increases and especially in the case of uncoordinated charging, this will put additional stress on the distribution grids. For this reason, this thesis investigates whether grid-friendly charging strategies can support the grid integration of electric vehicles and in addition fluctuating renewables. Therefore, two preventive and one active charging strategies are evaluated. With SimBEV , a tool is co-developed for the creation of driving profiles and the determination of the charging demand of electric vehicles. The demand is allocated locally and transferred in the form of load time series to the spatially and temporally high-resolution grid models of five typical medium voltage grids including underlying low voltage grids. Subsequently, a load flow analysis is used to highlight any grid issues. Finally, the curtailment of load and generation necessary to solve any arising grid issues is determined. Based on these values, investigations are made about the extent to which the charging strategies are able to avoid or reduce critical grid stresses. A preventive charging strategy with reduced charging power can successfully reduce grid issues arising from high load. In contrast, a preventive charging strategy with alternating charge time windows can reduce the load-induced stresses only to a small extent. Furthermore, the preventive charging strategies also lead to an increase in the curtailment of fluctuating renewables, as the charging demand is reduced during periods of high feed-in. With the active charging strategy, which is dependent on the residual load in the grid, the curtailment of load is reduced more strongly in some cases, but less strongly in most cases than with the preventive charging strategy with reduced charging capacities. On the other hand, especially in photovoltaic-dominated grids, only the active charging strategy offers the potential to reduce the curtailment of generation and thus supports the grid integration of fluctuating renewables. The success of the active charging strategy depends strongly on the extent to which the global residual load in the medium voltage grid reflects the situations in the individual grid sections. Primarily in wind-dominated grids, the global residual load proves to be an insufficient optimization parameter, which leads to negative effects on the curtailment of load and generation.

description: Let $f(n,\ell)$ be the maximum integer such that every set of $n$ points in the plane with at most $\ell$ collinear contains a subset of $f(n,\ell)$ points with no three collinear. First we prove that if $\ell \leq O(\sqrt{n})$ then $f(n,\ell)\geq Ω(\sqrt{\frac{n}{\ln \ell}})$. Second we prove that if $\ell \leq O(n^{(1-ε)/2})$ then $f(n,\ell) \geq Ω(\sqrt{n\log_\ell n})$, which implies all previously known lower bounds on $f(n,\ell)$ and improves them when $\ell$ is not fixed. A more general problem is to consider subsets with at most $k$ collinear points in a point set with at most $\ell$ collinear. We also prove analogous results in this setting.

title: The Impact of Unemployment Insurance and Unsecured Credit on Business Cycles
Creators: name: Irwin, Michael
Publisher: name: Bank of Canada
Year: 2023

description: I study how unsecured credit affects the extent to which unemployment insurance (UI) policies smooth cyclical fluctuations in aggregate consumption. To do so, I develop a real business cycle model with incomplete asset markets, frictional labor markets, and defaultable debt. Using empirically consistent unemployment dynamics over the business cycle, the model generates the cyclical properties of unsecured revolving credit balances and consumer bankruptcies in the data. The model is used to quantify the aggregate implications of a policy that extends the duration of UI during recessions. The main quantitative result of this paper is that unsecured credit amplifies the extent to which UI policies smooth aggregate consumption fluctuations over the business cycle. Extensions in the duration of UI mitigate the rise in consumer bankruptcies during recessions. They also mitigate the rise in the risk premium on unsecured borrowing, which allows households to better smooth consumption.
description: Cette étude porte sur la façon dont le crédit non garanti influence la capacité de l’assurance-emploi à lisser les fluctuations cycliques de la consommation globale. Je crée un modèle de cycle économique réel combinant des marchés d’actifs incomplets, des marchés du travail frictionnels et des créances présentant un risque de défaut. En introduisant une dynamique du chômage empiriquement cohérente avec le cycle économique, le modèle reproduit les propriétés cycliques des soldes de crédit renouvelable non garanti et des faillites personnelles. J’utilise ensuite le modèle pour quantifier les répercussions globales d’une politique qui prolonge l’assurance-emploi pendant les récessions. Le principal résultat quantitatif de l’étude est que le crédit non garanti amplifie l’effet de lissage des politiques d’assurance-emploi sur les fluctuations de la consommation globale au cours du cycle économique. La prolongation de l’assurance-emploi atténue l’accroissement des faillites personnelles pendant les récessions, de même que la hausse de la prime de risque liée aux emprunts non garantis, ce qui permet aux ménages de mieux lisser leur consommation.

description: The even spin W^e_\infty algebra that is generated by the stress energy tensor together with one Virasoro primary field for every even spin s \geq 4 is analysed systematically by studying the constraints coming from the Jacobi identities. It is found that the algebra is characterised, in addition to the central charge, by one free parameter that can be identified with the self-coupling constant of the spin 4 field. We show that W^e_\infty can be thought of as the quantisation of the asymptotic symmetry algebra of the even higher spin theory on AdS_3. On the other hand, W^e_\infty is also quantum equivalent to the so(N) coset algebras, and thus our result establishes an important aspect of the even spin minimal model holography conjecture. The quantum equivalence holds actually at finite central charge, and hence opens the way towards understanding the duality beyond the leading 't Hooft limit.

Synthesis of sup-interpretations: a survey

Publisher: name: arXiv
Year: 2012
Subjects: subject: Computational Complexity (cs.CC)
subject: FOS: Computer and information sciences

description: In this paper, we survey the complexity of distinct methods that allow the programmer to synthesize a sup-interpretation, a function providing an upper- bound on the size of the output values computed by a program. It consists in a static space analysis tool without consideration of the time consumption. Although clearly related, sup-interpretation is independent from termination since it only provides an upper bound on the terminating computations. First, we study some undecidable properties of sup-interpretations from a theoretical point of view. Next, we fix term rewriting systems as our computational model and we show that a sup-interpretation can be obtained through the use of a well-known termination technique, the polynomial interpretations. The drawback is that such a method only applies to total functions (strongly normalizing programs). To overcome this problem we also study sup-interpretations through the notion of quasi-interpretation. Quasi-interpretations also suffer from a drawback that lies in the subterm property. This property drastically restricts the shape of the considered functions. Again we overcome this problem by introducing a new notion of interpretations mainly based on the dependency pairs method. We study the decidability and complexity of the sup-interpretation synthesis problem for all these three tools over sets of polynomials. Finally, we take benefit of some previous works on termination and runtime complexity to infer sup-interpretations.

description: We investigate the impact of feedback - from supernovae (SNe), active galactic nuclei (AGN) and a photo-ionizing background at high redshifts - on the neutral atomic hydrogen (HI) mass function, the $b_{\rm J}$ band luminosity function, and the spatial clustering of these galaxies at $z$=0. We use a version of the semi-analytical galaxy formation model GALFORM that calculates self-consistently the amount of HI in a galaxy as a function of cosmic time and links its star formation rate to its mass of molecular hydrogen (H$_2$). We find that a systematic increase or decrease in the strength of SNe feedback leads to a systematic decrease or increase in the amplitudes of the luminosity and HI mass functions, but has little influence on their overall shapes. Varying the strength of AGN feedback influences only the numbers of the brightest or most HI massive galaxies, while the impact of varying the strength of photo-ionization feedback is restricted to changing the numbers of the faintest or least HI massive galaxies.Our results suggest that the HI mass function is a more sensitive probe of the consequences of cosmological reionization for galaxy formation than the luminosity function. We find that increasing the strength of any of the modes of feedback acts to weaken the clustering strength of galaxies, regardless of their HI-richness. In contrast, weaker AGN feedback has little effect on the clustering strength whereas weaker SNe feedback increases the clustering strength of HI-poor galaxies more strongly than HI-rich galaxies. These results indicate that forthcoming HI surveys on next generation radio telescopes such as the Square Kilometre Array and its pathfinders will be exploited most fruitfully as part of multiwavelength survey campaigns.

description: We consider the time evolution after sudden quenches of global parameters in translational invariant Hamiltonians and study the time average expectation values and entanglement entropies in finite chains. We show that in noninteracting models the time average of spin correlation functions is asymptotically equal to the infinite time limit in the infinite chain, which is known to be described by a generalized Gibbs ensemble. The equivalence breaks down considering nonlocal operators, and we establish that this can be traced back to the existence of conservation laws common to the Hamiltonian before and after the quench. We develop a method to compute the leading finite-size correction for time average correlation functions and entanglement entropies. We find that large corrections are generally associated to observables with slow relaxation dynamics.

description: Four centuries before modern statistical linguistics was born, Leon Battista Alberti (1404--1472) compared the frequency of vowels in Latin poems and orations, making the first quantified observation of a stylistic difference ever. Using a corpus of 20 Latin texts (over 5 million letters), Alberti's observations are statistically assessed. Letter counts prove that poets used significantly more a's, e's, and y's, whereas orators used more of the other vowels. The sample sizes needed to justify the assertions are studied, and proved to be within reach for Alberti's scholarship.

description: Der Aufbau fluoreszenter von in 5-Position konjungierter 4-Hydroxy-1,3-thiazole ist Gegenstand der vorliegenden Arbeit. Dabei wird sowohl auf stilben- als auch styrenartige heterocyclische Analoga eingegangen. Ausgangstoff für die Synthesen war dabei 4-Ethoxy-2-(pyridin-2-yl)-1,3-thiazol-5-carbaldehyd. Dieses konnte mittels McMurry-Reaktion erfolgreich homogekuppelt werden. Voraussetzung hierfür ist der Einsatz von Titan(III)chlorid, bei einer in situ Erzeugung aus einer Ti(IV) Spezies versagt die Reaktion. Sogar gekreuzte McMurry-Reaktionen sind so beim Einsatz von elektronenreichen, z.B. Vanillin basierenden, Reaktionspartnern realisierbar. Es erwies sich teilweise als vorteilhaft, gekreuzte konjungierte Systeme, welche eine Thiazol- und eine Phenylsubeinheit tragen, via Wittig-Reaktion zu realisieren, da hierbei die Ausbeuten deutlich höher waren. Auf diese Weise konnten auch trifunktionelle Phosphoniumsalze eingesetzt und damit sogenannte „starshaped molecules“ aufgebaut werden. Alle synthetisierten Produkte wurden charakterisiert und hinsichtlich ihrer fluoreszenten Eigenschaften eingehend untersucht. Neben dem Einsatz als Ausgangsstoff für weiterführenden Synthesen könnten die neuen Moleküle Anwendung in organische n Solarzellen, OLEDs oder FRET-Applikation finden.
description: The synthesis of fluorescent, in 5-position conjugated 4-hydroxy -1,3-thiazols is subject of the following work. Therefore, heterocyclic stilbene as well as styrene analogous derivatives are treated. Substrate for the synthesis was 4-ethoxy-2-(pyridine-2-yl)-1,3-thiazol-5-carbaldehyde. Homologous coupling via McMurry-reaction was successful under the use of titan(III)chloride, while the in situ formation was unsuccessful using a Ti(IV)-species. Even cross-coupled products were realised through the McMurry-reaction due to the usage of electron rich reaction partners, for instance Vanillin. It has been proven that cross-coupled systems which include a thiazol and a phenyl unit, could be achieved through Wittig-reaction with much higher yields. With the same method, trifuncional phosphoniumsalts could be converted into point symmetric “starshaped molecules”. All synthesised products were characterised and studied in depth regarding their fluorescent properties. Besides the use as starting material for further synthesis the new molecules could be utilized in the fields of organic solar cells, OLED or FRET applications.

description: We investigate the generalised diffeomorphisms in M-theory, which are gauge transformations unifying diffeomorphisms and tensor gauge transformations. After giving an En(n)-covariant description of the gauge transformations and their commutators, we show that the gauge algebra is infinitely reducible, i.e., the tower of ghosts for ghosts is infinite. The Jacobiator of generalised diffeomorphisms gives such a reducibility transformation. We give a concrete description of the ghost structure, and demonstrate that the infinite sums give the correct (regularised) number of degrees of freedom. The ghost towers belong to the sequences of rep- resentations previously observed appearing in tensor hierarchies and Borcherds algebras. All calculations rely on the section condition, which we reformulate as a linear condition on the cotangent directions. The analysis holds for n < 8. At n = 8, where the dual gravity field becomes relevant, the natural guess for the gauge parameter and its reducibility still yields the correct counting of gauge parameters.

description: The study investigates differences in firm productivity levels between France and Germany within the manufacturing sector. In addition, it analyzes the possible asymmetric effect that the Great Recession had on firm productivity in both countries. Our results reveal a systematic productivity advantage of Germany over France in the manufacturing industry over the period 2003-2013. This is explained by a lead of Germany over France in almost every sector considered. At the same the productivity gaps have significantly narrowed down over time. This result is explained both by a better performance of French firms in every sector and by a deterioration of German firms in some sectors, especially after the Great Recession.

description: More than 200 years after von Humboldt’s pioneering work on the treeline, our understanding of the cold distribution limit of upright plant growth is still incomplete. Here, we use wood anatomical techniques to estimate the degree of stem cell wall lignification in 1770 plant species from six continents. Contrary to the frequent belief that small plants are less lignified, we show that cell wall lignification in ‘woody’ herbs varies considerably. Although trees and shrubs always exhibit lignified cell walls in their upright stems, small plants above the treeline may contain less lignin. Our findings suggest that extremely cold growing season temperatures can reduce the ability of plants to lignify their secondary cell walls. Corroborating experimental and observational evidence, this study proposes to revisit existing theories about the thermal distribution limit of upright plant growth and to consider biochemical and biomechanical factors for explaining the global treeline position.

description: Recent studies demonstrated the violation of reciprocity in optical processes in low-symmetry magnetic crystals. In these crystals the speed of light can be different for counter-propagating beams. Correspondingly, they can show strong directional anisotropies such as direction dependent absorption also called directional dichroism[S. Bordács et al., Nat. Phys. 8, 734 (2012); M. Saito et al., J. Phys. Soc. Jpn. 77, 013705 (2008)]. Based on symmetry considerations, we identify the magnetic point groups of materials which can host such directional anisotropies and also provide a list of possible candidate materials to observe these phenomena. In most of these cases, the symmetry of the crystal allows directional anisotropy not only for optical processes but also for the propagation of beams of particles and scalar waves. We also predict new types of directional optical anisotropies -- besides the optical magnetoelectric effect and the magnetochiral dichroism investigated so far -- and specify the magnetic point groups of crystals where they can emerge.

description: Thin films of the proposed topological insulator PdLuBi - a Heusler compound with the C1b structure - were prepared on Ta-Mo-buffered MgO(100) substrates by co-sputtering from PdBi2 and Lu targets. Epitaxial growth of high-quality PdLuBi films was confirmed by X-ray spectrometry and reflection high-energy electron diffraction. The root-mean-square roughness of the films was as low as 1.45 nm, although the films were deposited at high temperature. The film composition is close to the ideal stoichiometric ratio. The valence band spectra of the PdLuBi films, observed by hard X-ray photoelectron spectroscopy, correspond perfectly to the ab-initio-calculated density of states.

description: This study aims to make the comparison of the kinematics and possible injury values of the occupant in the highly reclined seating position in two cases: the first case is without the braking maneuver prior to the frontal crash, and the second case is considering the braking maneuver prior to the impact. This study used the MADYMO human body model 50th percentile mid-size male seated on the front passenger seat model with the seatback reclined rearward 53° (fully reclined seatback) to simulate the occupant biomechanics and behavior during a frontal collision. To achieve the study aim, two simulation models were created. The first model is called the non-precrash model (VaAM-O). It was set to simulate the occupant kinematics in the fully reclined initial seating posture in the 200 ms of a crash without the braking maneuver before the crash. The second model, called the precrash model (VaAM-I), identified the occupant’s initial position after the car model performed a 1s deceleration of a braking maneuver. VaAM-I has then also simulated the occupant kinematics in 200 ms of a crash. This study showed a significant difference in the occupant’s posture at the beginning of the crash phase in the two cases. The upper torso of VaAM-I rotated up and moved forward earlier than VaAM-O prior to the crash phase due to the influence of the braking maneuver, and at the 50 ms, when the airbag deployed completely, the head had no contact with the airbag, and the head in VaAM-I forwarded to the airbag closer than VaAM-O about 24% of the distance to the airbag. This study supplements the value data for the study of the out-of-position OOP of the occupant in the frontal crash. The contact force and position contact between the head and the airbag could attract the audience’s attention. On the other hand, a comparison of the seatbelt force and the seatbelt contacts the body between the conventional seatbelt as in this study, and the seat-integrated seatbelt system in the case wherein the occupant seats on the front seat with a highly reclined seatback should be performed.

Der digitale Wandel muss in der Lehre aufgegriffen und dafür Konzepte zu seiner Implementierung entwickelt werden. Der Beitrag schlägt ein mögliches praxisorientiertes Konzept vor und stellt es zur Diskussion: Die Verwendung von Smartphones – hier am Beispiel einer Stadtführungs-App – zur Begleitung digitaler Lehr-Lern-Prozesse im urbanen Raum. Die Erstellung digitaler Stadtführungen soll die Lernenden dabei unterstützen, den urbanen Raum aus einem historischen Blickwinkel zu erschließen. Angewandt und überprüft wurde das Konzept in Rom im Rahmen eines Kooperationsprojekts zwischen der Albert-Ludwigs-Universität und Pädagogischer Hochschule Freiburg.

description: Die germanistische Auseinandersetzung mit den deutschen Kalendern beschränkte sich bisher auf unzusammenhängende Beiträge zu einzelnen Kalendertexten und -textsorten. Eine die Grenzen der einzelnen Textsorten, Epochen und akademischen Disziplinen übergreifende Gesamtdarstellung gibt es nicht. Dieser Beitrag macht auf diese bislang kaum wahrgenommene literaturwissenschaftliche Forschungslücke aufmerksam. Er umreißt grob die Entwicklungslinien deutscher Kalender vor 1600, gibt einen knappen Überblick über die bisherige Forschung und zeigt konkrete Desiderata auf, um schließlich Leitthemen für eine zukünftige Kalenderforschung zu formulieren.
description: Within German studies, the discussion of German calendars has so far been limited to incoherent contributions to individual calendar texts and text types. There is no overall presentation that transcends the boundaries of the different genres, epochs and academic disciplines. This article draws attention to this research gap in German literary studies, which has so far hardly been noticed. It roughly describes the development of German calendars be-fore 1600, gives a brief overview of previous research and points out concrete desiderata in order to finally formulate key themes for future calendar research.

description: Software re-modularization is an old preoccupation of reverse engineering research. The advantages of a well structured or modularized system are well known. Yet after so much time and efforts, the field seems unable to come up with solutions that make a clear difference in practice. Recently, some researchers started to question whether some basic assumptions of the field were not overrated. The main one consists in evaluating the high-cohesion/low-coupling dogma with metrics of unknown relevance. In this paper, we study a real structuring case (on the Eclipse platform) to try to better understand if (some) existing metrics would have helped the software engineers in the task. Results show that the cohesion and coupling metrics used in the experiment did not behave as expected and would probably not have helped the maintainers reach there goal. We also measured another possible restructuring which is to decrease the number of cyclic dependencies between modules. Again, the results did not meet expectations.

description: The aim of this research is to develop a wearable daytime light dosimeter that can be implemented in a lighting solution, to offer individual, automated and optimized lighting conditions. To do so, the dosimeter is orientated towards the standard CIE S 026/E:2018 “CIE System for Metrology of Optical radiation for ipRGC-Influenced Responses to Light”, considering the spectral sensitivities of the different retinal receptors and the impact of the field of view. For optimized lighting conditions, the luminaire’s luminous intensity distribution must be adaptable in spectral power distribution and in direction. If the optimal spectral light incidence distribution for ipRGC-influenced responses to light purposes is known, the required luminous intensity distribution of a luminaire for a certain room geometry with certain room surface reflection values can be calculated. For this purpose, a spectral radiosity algorithm is in development. With a feedback loop between luminaire and dosimeter the light distribution can be continuously adapted as required.

description: We present a set of Bell inequalities for multiqubit quantum systems. These Bell inequalities are shown to be able to detect multiqubit entanglement better than previous Bell inequalities such as Werner-Wolf-Zukowski- Brukner ones. Computable formulas are presented for calculating the maximal violations of these Bell inequalities for any multiqubit states.

description: Seit der Entdeckung des ipRGC Rezeptors gilt dem Forschungsgebiet nicht-visuelle (eng. non-imageforming, NIF) Wirkung von Licht neue Aufmerksamkeit. “Nicht-visuell” bedeutet, dass ein Fehlen des ipRGC (engl. intrinsically photosensitive retinal ganglion cells) Rezeptors keine Auswirkung auf das Sehen des Menschen hätte, jedoch wären Auswirkungen auf den circadianen Rhythmus des Menschen zu beobachten. Der ipRGC Rezeptor ist eine fotosensitive Ganglienzelle und mit nur weniger als 5% aller Ganglienzellen auf der Netzhaut des Auges verteilt. Der Rezeptor enthält das Photopigment Melanopsin. Wird der Rezeptor angeregt, so kann nachts die Ausschüttung des Hormons Melatonin durch die Zirbeldrüse gehemmt werden. Melatonin wird zunehmend im Laufe der Abendstunden und während der Nacht ausgeschüttet. Mit einer angepassten Beleuchtung könnte der circadiane Rhythmus eines Menschen unterstützt werden. Zur Untersuchung des Einflusses der Größe der Lichtquelle auf die Melatoninunterdrückung wurde im Jahr 2013 von Philipp Novotny et al. eine Probandenstudie mit 30 Versuchsteilnehmern durchgeführt. Diese wurden mit zwei unterschiedlich großen Flächen beleuchtet, um zu erforschen ob die Melatoninunterdrückung flächenabhängig ist. Der Melatoninspiegel wurde mittels Salivaproben untersucht. Bereits 2010 führte Philipp Novotny et al. dieselbe Probandenstudie mit 6 Versuchsteilnehmern durch. Die Auswertung der Studiendaten ergaben einen Trend, dass eine große Fläche die Melatoninausschüttung unter den verwendeten Versuchsbedingungen mehr unterdrücken könnte. Mittels einer größeren Teilnehmerzahl sollte dies 2013 wiederholt überprüft werden, jedoch wurden die Ergebnisse bisher noch nicht veröffentlicht. Dieser Beitrag stellt die ermittelten Ergebnisse von Novotny et al.s zweiter Studie vor, analysiert diese und berücksichtigt zusätzliche Faktoren wie z.B. den Einfallswinkel des Lichts in die Augen des Betrachters. Zur Charakterisierung der Lichtbedingungen und Beschreibung des Stimulus für nichtvisuelle Effekte wurde der Aufbau von Novotny et al.s Studie in einem LED Testraum am Fachgebiet Lichttechnik der Technischen Universität Berlin rekonstruiert. Hierbei soll eine fundierte Aussage über die Wirkung unterschiedlich großer Flächen getroffen werden.
