description: This paper gives an overview of the interdisciplinary design process of an electrically-powered high-lift system for future commercial aircraft, with a focus on the mixed-flow compressor performance. Based on the requirements of the high-lift system, a multi-objective optimization is used for the aero-mechanical design of the compressor stage. The demand for high pressure ratio and efficiency, together with the constrained installation space yields an unconventional mixed-flow compressor design with a transonic flow regime. To supply the required pressurized air for the high-lift system, rotational speeds of up to60,000rpm are necessary according to CFD analysis. A very compact integrated prototype of the compressor system is designed, including electrical machine and power electronics with high power-to-mass ratios. Performance predictions are validated at part load. To integrate the compressor stage into the prototype, some adjustments to the geometry become necessary. Additional CFD simulations reveal a big impact of the new inlet duct on the compressor performance due to inlet flow distortion. It is assumed that a fully-integrated design process, which includes all relevant interdependencies of the different components, would yield a better overall system design.

description: Requirements for a software product are mainly shared through a textual specification. One key ability in successful software organizations is a good requirements communication based on understandable information. Developers can only implement a useful and satisfying software product if they obtain and understand requirements properly. One challenge of writing requirements is to describe complex and interactive contents in an understandable manner. Videos offer a large potential to achieve such an easy-to-understand representation. Attached videos can enhance the reader’s understanding by using them as supplementary material for specifications. Despite their large potential, videos are not an established part of requirements specifications: The effort to produce videos is high, the corresponding motivation is low and the use of videos is cumbersome due to missing links between requirements and videos. We propose guidelines to support the identification of content which is appropriate to be supplemented by videos. We develope a starting set of guidelines that consider the different information types of a requirements specification with their presentation modes and characteristics. This paper presents an overview of our findings about improving the content-related linking between requirements and videos. We discuss the perspectives, advantages and obstacles for enhancing the comprehensibility of textual requirements conveyed by videos.

description: HD 142527 is a pre-transition disk with strong evidence for on-going planet formation. Recent observations show a disrupted disk with spiral arms, a dust-depleted inner cavity and the possible presence of gas streams driving gas from the outer disk towards the central star. We aim to derive the morphology of the disk, as well as the distribution and properties of the dust at its surface. We have obtained polarized differential images of HD 142527 at $H$ and $Ks$ bands with NaCo at the VLT. Combining these images with classical PSF-subtraction, we are able to derive the polarization degree of this disk. At $H$ band the polarization degree of the disk varies between 10% and 25%. This result cannot be reproduced by dust distributions containing highly porous material. The polarization is better matched by distributions of compact particles, with maximum sizes at least up to a few microns, in agreement with previous observations. We also observe two regions of low emission (nulls) in total and in polarized intensity. In particular, one of these nulls is at roughly the same position as the maximum of the horse-shoe shape observed in sub-millimeter continuum emission ALMA Band-7 (345 GHz) observations. We discuss the possible link between both features.

description: Water deficit is strongly affecting plant development and production. With the decrease in rainfall in many areas and the shortage of arable land for growing food crops, there is a demand to find alternative plant species that could be cultivated in non-arable land for food supplies and bioenergy. Balanites aegyptiaca L. is a multi-purpose tree belonging to the family of Balanitaceae distributed in North and West Africa, and West Asia. The species is considered as drought-tolerant serving as a source of many secondary metabolites and having a potential for biofuel production. This study aimed to examine and compare the morpho-physiological responses to water stress of six different B. aegyptiaca genotypes collected from different regions. Different regimes of soil volumetric water content (VWC 35% as a control, VWC 20% as moderate and VWC 5% as a severe drought stress) were chosen to finally select the most drought-tolerant genotype under greenhouse conditions. Several growth parameters, stomata conductance, photosynthetic efficiency, infrared thermography and metabolites contents were analyzed to investigate and compare the drought impact among B. aegyptiaca genotypes. The results indicate that at severe drought stress each genotype has an independent strategy to cope with the water shortage through a significant reduction in biomass parameters, early stomata closure combined with small changes in photosynthetic activity and producing a high concentration of ascorbic acid and proline. Finally, we found that i) Balanites genotypes showed different morphological and physiological responses to cope with the water shortage, ii) collections of two or three parameters could distinguish the water stress levels among the genotypes, and iii) genotype El-Kharga showed the highest drought-tolerance compared to the other genotypes. It shows the lowest magnitude of biomass reduction and early stomata closure as strategy of saving leaf water content under severe drought stress.

description: Given a $G$-invariant holomorphic 1-form with an isolated singular point on a germ of a complex analytic $G$-variety with an isolated singular point, its equivariant homological index and (reduced) equivariant radial index are defined as elements of the ring of complex representations of the finite group $G$. We show that these indices coincide on a germ of a smooth complex analytic $G$-variety. This makes it possible to consider the difference between them as a version of the equivariant Milnor number of a germ of a $G$-variety with an isolated singular point. For cyclic groups of order two and three we additionally describe another approach to prove the coincidence. This gives us a classification of singular points which cannot be excluded by deformations of 1-forms invariant with respect to an action of a cyclic group of order 3.
description: Zu einer gegebenen $G$-invarianten, holomorphen 1-Form auf dem Keim einer komplex-analytischen $G$-Varietät, die einen isolierten singulären Punkt aufweist, lassen sich der äquivariante homologische und der (reduzierte) äquivariante radiale Index als Elemente im Ring der komplexen Darstellungen der (endlichen) Gruppe $G$ definieren. Wir zeigen, dass diese Indizes auf einer glatten, komplex-analytischen $G$-Varietät übereinstimmen. Das ermöglicht uns, die Differenz zwischen diesen beiden Indizes als eine Version der äquivarianten Milnorzahl eines Keims einer $G$-Varietät mit isoliertem singulären Punkt zu betrachten. Für zyklische Gruppen der Ordnung zwei und drei geben wir außerdem einen alternativen Ansatz, um die Gleichheit der beiden Indizes zu zeigen. Dieser Ansatz liefert uns dann eine Klassifikation singulärer Punkte, die man nicht ausschließen kann, indem man Deformationen von 1-Formen, die invariant bezüglich der Wirkung einer zyklischen Gruppe der Ordnung 3 sind, betrachtet.

description: The development of high performance transparent conducting oxides (TCOs) is critical to many technologies from transparent electronics to solar cells. While n-type TCOs are present in many devices, current p-type TCOs are not largely commercialized as they exhibit much lower carrier mobilities, due to the large hole effective masses of most oxides. Here, we conduct a high-throughput computational search on thousands of binary and ternary oxides and identify several highly promising compounds displaying exceptionally low hole effective masses (up to an order of magnitude lower than state of the art p-type TCOs) as well as wide band gaps. In addition to the discovery of specific compounds, the chemical rationalization of our findings opens new directions, beyond current Cu-based chemistries, for the design and development of future p-type TCOs.

description: Research on tax compliance has shown that nonpecuniary incentives are very important for explaining tax compliance, and may outweigh the importance of enforcing tax payments with deterring instruments. This thesis seeks to deepen the understanding of why and how taxpayers respond to nonpecuniary incentives to comply with the tax code. In particular, this thesis examines the importance of framing, reputational concerns, and the interplay of trust in authorities and deterrence exerted by the state. The second central research objective in this thesis is to explore the societal determinants and characteristics of trust in government. This dissertations shows that the objective trustworthiness of institutions does not necessarily coincide with the subjective trust people put in them. However, even with lacking accountability and reliability of institutions, this thesis suggests positive direct links between trust in government and countries' economic development.

We show how to obtain finite values for the 2-point and n-point correlation functions without introducing counterterms in the Lagrangian. Also, we show how to obtain the renormalization group equation for the mass and the coupling constant. Finally, we found the dependence of the coupling constant with the energy scale and we discuss the validity of the observable-state model in terms of the projection procedure.

description: This work proposes a fast and straightforward method, called natural point correspondences (NaPoCo), for the extraction of road segment shapes from trajectories of vehicles. The algorithm can be expressed with 20 lines of code in Python and can be used as a baseline for further extensions or as a heuristic initialization for more complex algorithms. In this paper, we evaluate the performance of the proposed method. We show that (1) the order of the points in a trajectory can be used to cluster points among the trajectories for road segment shape extraction and (2) that preprocessing using polygonal approximation improves the results of the approach. Furthermore, we show based on “averaging GPS segments” competition results, that the algorithm despite its simplicity and low computational complexity achieves state-of-the-art performance on the challenge dataset, which is composed of data from several cities and countries.

description: Earth observation satellites yield a wealth of data for scientific, operational and commercial exploitation. However, the redistribution of mass in the system Earth is not yet part of the standard inventory of Earth Observation (EO) data products to date. It is derived from the Gravity Recovery and Climate Experiment (GRACE) mission and its Follow-On mission (GRACE-FO). Among many other applications, mass redistribution provides fundamental insights into the global water cycle. Changes in continental water storage impact the regional water budget and can, in extreme cases, result in floods and droughts that often claim a high toll on infrastructure, economy and human lives. The initiative for a European Gravity Service for Improved Emergency Management (EGSIEM) established three different prototype services to promote the unique value of mass redistribution products for Earth Observation in general and for early-warning systems in particular. The first prototype service is a scientific combination service to derive improved mass redistribution products from the combined knowledge of the European GRACE analysis centres. Secondly, the timeliness and reliability of such products is a primary concern for any early-warning system and therefore EGSIEM established a prototype for a near real-time service that provides dedicated gravity field information with a maximum latency of five days . Third, EGSIEM established a prototype of a hydrological / early warning service that derives wetness indices as indicators of hydrological extremes and assessed their potential for timely scheduling of high-resolution optical/radar satellites for follow-up observations in case of evolving hydrological extreme events.

description: We study phi photoproduction with various hadronic rescattering contributions included, in addition to the Pomeron and pseudoscalar meson-exchange diagrams. We find that the hadronic box diagrams can explain the recent experimental data in the vicinity of the threshold. In particular, the bump-like structure at the photon energy E_gamma \approx 2.3$ GeV is well explained by the K Lambda(1520) rescattering amplitude in the intermediate state, which is the dominant contribution among other hadronic contributions. We also find that the hadronic box diagrams are consistent with the observed spin-density matrix elements near the threshold region.

description: We consider isolated quantum systems with all of their many-body eigenstates localized. We define a sense in which such systems are integrable, and discuss a method for finding their localized conserved quantum numbers ("constants of motion"). These localized operators are interacting pseudospins and are subject to dephasing but not to dissipation, so any quantum states of these pseudospins can in principle be recovered via (spin) echo procedures. We also discuss the spreading of entanglement in many-body localized systems, which is another aspect of the dephasing due to interactions between these localized conserved operators.

For this purpose the emission of charged scalar and charged fermionic particles is investigated from charged BTZ black holes, with and without rotation. We use the quantum tunneling approach incorporating WKB approximation and spacetime symmetries. Another class of black hole which is asymptotic to a Sol three-manifold has also been investigated. This procedure gives us the tunneling probability of outgoing particles, and we compute the temperature of the radiation for these black holes. We also consider the quantum tunneling of particles from black hole asymptotic to Sol geometry.

La mobilité de son côté, qui évolue par ses formes et ses supports, instrumentalisant densité, affectation des sols, distances et accessibilité, semble constituer le déterminant commun aux changements de la forme urbaine et ne cesse d’alimenter la recherche scientifique. Dans le contexte spécifique de la ville de Mostaganem, qui opte pour le tramway dans le cadre d’une politique de généralisation des TCSP (Transports collectifs en site propre) en Algérie, nous abordons dans cet article, la question du rapport procédural des instruments d’urbanisme, comme le PDAU (Plan directeur d’aménagement et d’urbanisme) et le POS (Plan d’occupation des sols) avec des approches dédiées à la mobilité urbaine. L’exploration des données d’enquête OD (origine destination) et la lecture des répartitions des déplacements en bus et taxis dans l’AUIC (Agglomération urbaine intercommunale) de Mostaganem et leur rapprochement avec les affectations des sols, décidées en planification urbaine, nous ont révélé des écarts en équité spatiale et en accessibilité. La mobilité spatiale et sa régulation par des opérations de types TOD (Transit-oriented development) ou contrats d’axes, permet de mettre en cohérence les visées de la planification et de palier aux coupures urbaines. L’évolution urbaine de la ville sur le plan typo-morphologique, représente un fond d’informations capital pour mesurer l’impact de la mobilité spatiale sur les transformations urbaines.

description: We review the performance of the PBEint GGA functional (Phys. Rev. B 2010, 82, 113104) recently proposed to improve the description of hybrid interfaces, and we introduce its one-parameter hybrid form (hPBEint). We consider different well established benchmarks for energetic and structural properties of molecular and solid-state systems as well as model systems and newly developed benchmark sets for dipole moments and metal-molecule interactions. We find that PBEint and hPBEint (with 16.67% Hartree-Fock exchange) yield the overall best performance, working well for most of the considered properties and systems and showing a balanced behavior for different problems. In particular, due to their well-balanced accuracy, they perform well for the description of hybrid metal-molecule interfaces.

description: Studies investigating the effectiveness of school-related gender-based violence prevention programs seldom report on the extent to which students themselves value and recommend such programs. Yet, along with evidence about effectiveness in relation to shifts in knowledge, attitudes, or intentions, student-valuing is a significant indicator that the programs can make a positive contribution to students’ lives. This mixed-method study analyses survey and focus group data collected from ninety-two schools in three African countries (Tanzania, Zambia, and Eswatini). Students found the program contributed to improved peer relationships and identified the five most useful components as learning about gender equality and human rights, learning how to obtain help for those affected by violence, understanding and communicating about their emotions, strategies to avoid joining in with bullying and harassment, and understanding the effects of gender-based violence.

description: This dissertation contains three contributions to corporate tax planning. The first article examines stock price reactions to news about corporate tax avoidance and tax evasion. An event study shows that tax evasion generally has a negative impact on the capital market, while news of tax avoidance leads for firms with a low tax risk to positive capital market reactions. The second article deals with the effects of negotiation strategies of tax auditors and tax advisers on tax base adjustments in the context of a tax audit. A three-step estimation model shows that negotiation strategies have a severe impact on tax base adjustments. Tax auditors can increase tax base adjustments by ten percentage points when opting for a competitive strategy instead of a neutral strategy. The third article deals with the tax-induced income shifting of corporations. The results imply that firms are shifting income from high marginal tax rate periods to low marginal tax rate periods. This effect is particularly pronounced for family firms. Furthermore, firms' real activities manipulation is negatively affected by firms' marginal tax rate.

description: Disclosed financial reports have an important influence on the behavior of the corporatemanagement. Managers have different motivations to generate a desired view on theircompanies and this can lead to undesirable side effects in the form of managerial manipulation. Selected issues of earnings management incentives arising from the managerialcompensation, career concerns and socioemotional intentions of family-members are investigated in this dissertation.

description: We show that Khovanov homology (and its sl(3) variant) can be understood in the context of higher representation theory. Specifically, we show that the combinatorially defined foam constructions of these theories arise as a family of 2-representations of categorified quantum sl(m) via categorical skew Howe duality. Utilizing Cautis-Rozansky categorified clasps we also obtain a unified construction of foam-based categorifications of Jones-Wenzl projectors and their sl(3) analogs purely from the higher representation theory of categorified quantum groups. In the sl(2) case, this work reveals the importance of a modified class of foams introduced by Christian Blanchet which in turn suggest a similar modified version of the sl(3) foam category introduced here.

description: Römische Reiterhelme mit Gesichtsmasken gehören zu den seltenen Funden antiker Militärausrüstung. Im Rahmen eines deutsch-niederländischen Gemeinschaftsprojekts 2006/2007 wurden nun neun Helme des 1. und 2. Jhs. n. Chr. aus den Sammlungen des Museums Het Valkhof in Nijmegen, des LVR – Römermuseums Xanten und des LVR – Landesmuseums Bonn umfassend analysiert. Zum Verständnis der historischen Techniken wurden außerdem verschiedene Experimente und Rekonstruktionsversuche durchgeführt. Die Auswertung sämtlicher Untersuchungen ergab, dass die Helme aus offenbar mehrlagigen Eisenblechen geschmiedet und mit einem in Teilen noch erhaltenen dünnen Silberblech überzogen sind. Bei vier Helmen zeigen die Außenseiten der Hinterhauptkalotten noch Reste aufwändig gearbeiteter Flechtbandverzierungen aus Pferdehaaren. Für die Montagen der Silberbleche auf den Gesichtsmasken und des textilen Überzugs konnte die Verwendung eines mehrkomponentigen Klebemittels nachgewiesen werden.

Variational Monte Carlo approach to the two-dimensional Kondo lattice model

description: We study the phase diagram of the Kondo-lattice model with nearest-neighbor hopping in the square lattice by means of the variational Monte Carlo technique. Specifically, we analyze a wide class of variational wave functions that allow magnetic and superconducting order parameters, so to assess the possibility that superconductivity might emerge close to the magnetic instability, as often observed in heavy fermion systems. Indeed, we do find evidence of d-wave superconductivity in the paramagnetic sector, i.e., when magnetic order is not allowed in the variational wave function. However, when magnetism is allowed, it completely covers the superconducting region, which thus disappears from the phase diagram.

description: This thesis contains five essays on fractional cointegration, seasonal fractional cointegration and seasonal long memory. After an introduction in the first Chapter, Chapter 2 reviews competing tests for fractional cointegration, since no standard approach emerged so far. It provides a synthesis of the literature and a detailed comparative Monte Carlo study to guide empirical researchers in their choice of appropriate methodologies. In Chapter 3, the previously reviewed methods are applied in the context of the European government bond market analyzing the degree of market integration. Chapter 4 deals with possible breaks in the persistence structure of a fractional cointegrating relationship. It introduces test procedures for no fractional cointegration that are robust for such a break. The following Chapters 5 and 6 consider another phenomenon in time series, namely seasonality, in particular seasonal long memory. Chapter 5 examines multivariate seasonal data and the concomitant possibility of seasonal fractional cointegration. Chapter 6 takes a different perspective and deals with univariate seasonal time series and proposes a test for seasonal long memory with a known frequency is proposed.
