description: Autonomuous transportation systems require navigation performance with a high level of integrity. As Global Navigation Satellite System (GNSS) real-time kinematic (RTK) solutions are needed to ensure lane level accuracy of the whole system, these solutions should be trustworthy, which is often not the case in urban environments. Thus, the prediction of integrity for specific routes or trajectories is of interest. The carrier-to-noise density ratio (C/N0) reported by the GNSS receiver offers important insights into the signal quality, the carrier phase availability and subsequently the RTK solution integrity. The ultimate goal of this research is to investigate the predictability of the GNSS signal strength. Using a ray-tracing algorithm together with known satellite positions and 3D building models, not only the satellite visibility but also the GNSS signal propagation conditions at waypoints along an intended route are computed. Including antenna gain, free-space propagation as well as reflection and diffraction at surfaces and vegetation, the predicted C/N0 is compared to that recorded by an Septentrio Altus receiver during an experiment in an urban environment in Hannover. Although the actual gain pattern of the receiving antenna was unknown, good agreements were found with small offsets between measured and predicted C/N0.
Measurement of D*+/- meson production in jets from pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

description: This paper reports a measurement of D*+/- meson production in jets from proton-proton collisions at a center-of-mass energy of sqrt(s) = 7 TeV at the CERN Large Hadron Collider. The measurement is based on a data sample recorded with the ATLAS detector with an integrated luminosity of 0.30 pb^-1 for jets with transverse momentum between 25 and 70 GeV in the pseudorapidity range |eta| < 2.5. D*+/- mesons found in jets are fully reconstructed in the decay chain: D*+ -> D0pi+, D0 -> K-pi+, and its charge conjugate. The production rate is found to be N(D*+/-)/N(jet) = 0.025 +/- 0.001(stat.) +/- 0.004(syst.) for D*+/- mesons that carry a fraction z of the jet momentum in the range 0.3 < z < 1. Monte Carlo predictions fail to describe the data at small values of z, and this is most marked at low jet transverse momentum.

description: Continuous generating grinding processes have largely replaced discontinuous profile grinding processes in gear manufacturing due to their higher productivity. On order to transfer the advantage of the productivity benefits of this process to tool grinding, the continuous generating grinding was adapted to the manufacture of cutting tools. However, this novel approach of using continuous generating grinding processes for tool grinding has not been widely investigated. Therefore, the aim of this study is to investigate the influence of cutting speed, feed and radial depth of cut on the process result and thus to generate initial knowledge for the process design. Subsequently, the influence of these parameters on the grinding worm wear as well as on the cutting edge quality and surface properties of the ground milling tools are investigated. The results show that an increase of the radial depth of cut leads to a reduction of the process time by the factor of four without significantly influencing the wear of the grinding worm tooth. Furthermore, an increase of the cutting speed only leads to an increase in the initial wear of the grinding worm after the dressing process. For this reason, the cutting speed offers the potential to further increase the productivity of the process. The microgeometry of the cutting edge of the ground milling tool is mainly affected by the feed and the macro geometry by the feed and radial depth of cut.

description: We consider $d$-dimensional static spacetimes in Einstein gravity with a cosmological constant in the presence of a minimally coupled massless scalar field. The spacetimes have a $(d-2)$-dimensional base manifold given by an Einstein space and the massless scalar field depends only on the radial coordinate. The field equations are decoupled in the general case, and can be solved exactly for the cases when either the cosmological constant vanishes or the base manifold is Ricci flat. We focus on the case of a negative cosmological constant and a Ricci-flat base manifold. The solution has a curvature singularity located at the origin, where also the scalar field diverges. Since there is no event horizon surrounding this singularity, the solution describes a naked singularity dressed with a nontrivial scalar field. This spacetime is an asymptotically locally anti-de Sitter one when the Ricci-flat base manifold is locally flat. The asymptotic solution for an arbitrary Einstein base manifold is found and the corresponding mass, calculated through the canonical generator of the time-translation invariance, is shown to be finite. The contribution to the mass from the scalar field at infinity is also discussed.

description: Wo ein Parkplatz ist, könnte auch eine Grünfläche oder ein Fahrradweg sein. Verschiedene Nutzungsansprüche konkurrieren zunehmend um den knappen öffentlichen Stadtraum. Parkraummanagement stellt daher einen wichtigen Baustein in der lokalen Verkehrspolitik dar, um Parkplätze effizienter zu nutzen, nachhaltige Mobilität zu fördern und zum Klimaschutz beizutragen. ILS-Wissenschaftlerin Janina Welsch hat in Düsseldorf-Bilk das Mobilitätsverhalten der Bewohner*innen erhoben und wie konkrete Maßnahmen - wie eine Ausweitung des Bewohnerparkens oder die Umwandlung von Parkplätzen - bewertet werden.

Auch wenn sich Unterschiede zwischen Pkw-Besitzer*innen und Menschen ohne eigenes Auto zeigen, stimmen viele einer potentiellen Veränderung im Parkraummanagement zu. Ausgewählte Ergebnisse sind im ILS-TRENDS „Parken – was sonst? Wie Bewohner*innen in Düsseldorf-Bilk Mobilität und Parken bewerten“ erschienen.

Das Projekt, dessen Ergebnisse für ILS-TRENDS aufbereitet wurden, wurde in Kooperation mit dem Ministerium für Heimat, Kommunales, Bau und Digitalisierung des Landes Nordrhein-Westfalen (MHKBD) und dem Ministerium für Umwelt, Naturschutz und Verkehr des Landes Nordrhein-Westfalen (MUNV) durchgeführt.

description: Deutschland will bis 2045, Europa bis 2050 klimaneutral werden. Um dieser Herausforderung begegnen zu können, ist es erforderlich, sich stärker in Richtung einer Kreislaufwirtschaft zu orientieren: Abfallvermeidung, Wiederverwendung und Recycling helfen dabei, primäre Ressourcen und die Emissionen bei der Produktion von Grundstoffen wie Stahl, Zement und Kunststoff einzusparen. Ohne dies, allein durch eine Umstellung der Produktion auf klimaneutrale Prozesse, entstünden erhebliche Kosten und ein sehr hoher Bedarf an erneuerbarer Energie. Dazu bedarf es jedoch geeigneter Politikmaßnahmen. So sollten Klimakosten vollständig in den Grundstoffpreisen berücksichtigt werden und mithilfe von Standards und Anreizen die Recycelbarkeit von Produkten sichergestellt werden. Zudem sollte das Verbraucherbewusstsein durch zuverlässige Informationen über Umweltauswirkungen gestärkt und Investitionen in eine verbesserte Recyclinginfrastruktur angeregt werden. Für die effektive Umsetzung dieser Maßnahmen sind klare Ziele und eine Festlegung von Verantwortlichkeiten notwendig.

description: We study the optically pumped nuclear spin polarization in a single GaAs/AlGaAs quantum well in the quantum Hall system. We apply resistive detection via the contact hyperfine interaction, which provides high sensitivity and selectivity, to probe a small amount of polarized nuclear spins in a single well. The properties of the optical nuclear spin polarization are clearly observed. We theoretically discuss the nuclear spin dynamics accompanied with doped electrons to analyze the experimental data. The optical nuclear polarization spectra exhibit electron-spin-resolved lowest Landau level interband transitions. We find that the phonon emission process, which normally assists the optical pumping process, influences the optical nuclear spin polarization. We also discuss that the electron-electron interaction can play an important role in the optical nuclear spin polarization.

description: An electron antineutrino mass has been measured in tritium beta-decay in the "Troitsk nu-mass" experiment. The setup consists of a windowless gaseous tritium source and an electrostatic electron spectrometer. The whole data set acquired from 1994 to 2004 was reanalysed. A thorough selection of data with the reliable experimental conditions has been performed. We checked every known systematic effect and got the following experimental estimate for neutrino mass squared m_{nu}^{2}=-0.67+/- 2.53 {eV}^{2}. This gives an experimental upper sensitivity limit of m_{nu}<2.2 eV and upper limit estimates m_{nu}<2.12 eV, 95% C.L. for Bayesian statistics and m_{nu}<2.05 eV, 95% C.L. for the Feldman and Cousins approach.

description: Cheddar-type cheese produced from buttermilk had softer texture than standard cheddar cheese due to lower fat content of buttermilk. Fat is extremely important for the functional characteristics and optimum textural attributes of cheese. The effect of different fat contents of buttermilk on chemical characteristics of cheddar-type cheese is not previously investigated. This investigation was conducted to know the effect of different fat contents of buttermilk on fatty acids composition, organic acids, vitamins, lipolysis and sensory characteristics of cheddar-type cheese. Cheddar-type cheese was produced from buttermilk having 1, 1.75, 2.50 and 3.25% fat contents (control, T1, T2 and T3). Fat content of control, T1, T2 and T3 were 9.81, 16.34, 25.17 and 31.19%. Fatty acids profile was determined on GC–MS, organic acids and vitamin A and E were determined on HPLC. Free fatty acids, peroxide value and cholesterol were determined. Cheddar-style cheese produced from buttermilk (1% fat) showed that it had softer texture and lacking typical cheese flavor. Gas chromatography–mass spectrometry (GC–MS) analysis showed that long-chain unsaturated fatty acids in control, T1, T2 and T3 samples were 45.88, 45.78, 45.90 and 46.19 mg/100 g. High Performance Liquid Chromatography (HPLC) analysis showed that lactic acid, propionic acid, citric acid and acetic acid gradually and steadily increased during the storage interval of 90 days. At the age of 90 days, lactic acid in control, T1, T2 and T3 was 4,789, 5,487, 6,571 and 8,049 ppm, respectively. At the end of ripening duration of 90 days, free fatty acids in control, T1, T2 and T3 were 0.29, 0.31, 0.35 and 0.42% with no difference in peroxide value. Stability of vitamin A after 90 days storage control, T1, T2 and T3 was 87.0, 80.0, 94.0 and 91.0%. Flavor score of cheddar-type cheese produced from butter milk having 1.0, 2.5 and 3.25% fat content was 81, 89 and 91% of total score (9). Hence, it is concluded that cheddar-type cheese can be produced from buttermilk having 2.5 and 3.25% fat contents with acceptable sensory attributes. Application of buttermilk for the production of other cheese varieties should be studied.
Coherence, consistency, contradiction : portraits of postsecondary educators seeking ecological integrity
Creators: name: Timmerman, Nora Colleen
Publisher: name: University of British Columbia
Year: 2024

description: The purpose of this dissertation is to inquire into, critically explore, and share thoughtful possibilities for teaching and living with ecological integrity. Ecological integrity is defined as the ideal of coherence between one’s actual, day-to-day habits of mind and body, and one’s ecologically based morals, principles, or ethical ideals. Ecological educators often sense contradiction between their ecological ideals and their day-to-day lives. Recognizing that many ecological injustices have their roots in socio-cultural patterns of instrumentalism and anthropocentrism, they see how the educational institutions in which they work reflect and reproduce the injustices they aim to counteract. In this research, I study how three respected, ecological, postsecondary educators negotiate their resistance to and reinscription of ecologically problematic norms. While this research does not intend to preach, oversimplify, serve as a “recipe,” or glorify these educators, it does suggest that there are lessons, challenges and inspirations to be had from sharing stories of the aspirations and actualities of these educators’ lives. The question at the forefront of this research asks: How do respected educators who recognize and critique the ways in which dominant, modern, institutionalized education contributes to ecological concerns, work toward and conceptualize ecological integrity within their personal and professional lives? Using a combination of narrative and ethnographic inquiry called “portraiture,” I explored participants’ professional educational practice and their personal home and community lives, inquiring into their varied conceptions and enactments of ecological integrity. As part of this inquiry, I engaged with participants during week-long site visits, pre- and post-visit interviews, and reviews of their publications. Theme- and aesthetic-based analyses were conducted to create three deeply detailed stories of participants. While the stories themselves represent much of the “results” of the research, the dissertation also analyzes participants’ varied conceptions of contradiction and complicity, their chosen commitments, their decisions to “opt out” of certain practices, and their self assessments of ecological integrity, each of which carry both personal and collaborative dimensions. In conclusion, this research does not suggest one, final definition of ecological integrity, but rather offers readers a range of interpretations upon which they can reflect and build their own.

description: We study the superfluidity of a spin-orbit coupled Bose-Einstein condensate (BEC) by computing its Bogoliubov excitations, which are found to consist of two branches: one is gapless and phonon-like at long wavelength; the other is typically gapped. These excitations imply a superfluidity that has two new features: ({\it i}) due to the absence of the Galilean invariance, one can no longer define the critical velocity of superfluidity independent of the reference frame; ({\it ii}) the superfluidity depends not only on whether the speed of the BEC exceeds a critical value, but also on {\it cross helicity} that is defined as the direction of the cross product of the spin and the kinetic momentum of the BEC.

description: Aktuell machen sich 40 Prozent der Menschen in Deutschland Sorgen um ihre eigene wirtschaftliche Situation. In ernsten finanziellen Schieflagen ist bislang aber nur eine Minderheit. Im Jahr 2020 galten 6,85 Millionen Personen in Deutschland als überschuldet, konnten ihren Zahlungsverpflichtungen also über längere Zeit nicht nachkommen. Diese Zahl weicht nicht signifikant von den Vorjahren ab. Dabei geht jeder zehnte Überschuldungsfall auf problematisches Konsumverhalten zurück – Tendenz steigend. Eine repräsentative Haushaltsbefragung zeigt, dass mangelnde Selbstkontrolle und geringe finanzielle Bildung mit höheren Zahlungsschwierigkeiten bei Konsumentenkrediten verbunden sind. Der kausale Zusammenhang zwischen diesen Größen wird durch ein ökonomisches Experiment bestätigt. Für die Politik ist daher neben einem effektiven Verbraucherschutz bei Konsumentenkrediten eine nationale Strategie zur Finanzbildung hilfreich, da sie die Auswirkungen von geringer Selbstkontrolle abfedern kann.

Random pinning model with finite range correlations : disorder relevant regime

Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: The purpose of this paper is to show how one can extend some results on disorder relevance obtained for the random pinning model with i.i.d disorder to the model with finite range correlated disorder. In a previous work, the annealed critical curve of the latter model was computed, and equality of quenched and annealed critical points, as well as exponents, was proved under some conditions on the return exponent of the interarrival times. Here we complete this work by looking at the disorder relevant regime, where annealed and quenched critical points differ. All these results show that the Harris criterion, which was proved to be correct in the i.i.d case, remains valid in our setup. We strongly use Markov renewal constructions that were introduced in the solving of the annealed model.

Ils ont trouvé des effets plus importants sur le développement de l’orthographe et du vocabulaire dans le cas des classes ayant reçu un enseignement explicite des mots. Ces résultats permettent la révision des programmes de formation initiale et de formation continue afin d’accorder une place plus importante aux savoirs concernant les propriétés liées au sens, à l’usage et à la forme des mots et ainsi favoriser la mise en place de bonnes pratiques pour travailler le vocabulaire en classe.

British Columbia's 'carbon neutral government' mandate : influence on infrastructure decisions
Creators: name: Lau, Kim Yang
Publisher: name: University of British Columbia
Year: 2013

description: The ‘carbon neutral government’ mandate in British Columbia offers an excellent opportunity to study whether requiring public sector organizations to be ‘carbon neutral’ is an effective policy within an overall strategy to drastically reduce greenhouse gas emissions. While many have criticized the use of offsets to achieve ‘carbon neutrality’ and channeling of public funds to the private sector, others have pointed out that the mandate has forced public sector organizations to measure and manage their greenhouse gas emissions, and incentivized them to proceed with infrastructure projects that significantly reduced these emissions. Using a mixed methods case study approach, four post-secondary educational institutions in the Greater Vancouver region were selected, to investigate whether the ‘carbon neutral government’ mandate has influenced their decisions on infrastructure investments that would significantly reduce these organizations’ emissions. Through analyzing data on greenhouse gas emissions, energy consumption and expert interviews, this study provides a better understanding of the factors that motivate public sector organizations to take action to drastically reduce their greenhouse gas emissions, including the need to provide adequate resources and support mechanisms that will enable them to act so as to achieve the best possible policy outcome.

description: Collisions of particles in black holes' ergospheres may result in an arbitrarily large center of mass energy. This led recently to the suggestion (Banados et al., 2009) that black holes can act as ultimate particle accelerators. If the energy of an outgoing particle is larger than the total energy of the infalling particles the energy excess must come from the rotational energy of the black hole and hence this must involve a Penrose process. However, while the center of mass energy diverges the position of the collision makes it impossible for energetic particles to escape to infinity. Following an earlier work on collisional Penrose processes (Piran & Shaham 1977) we show that even under the most favorable idealized conditions the maximal energy of an escaping particle is only a modest factor above the total initial energy of the colliding particles. This implies that one shouldn't expect collisions around a black hole to act as spectacular cosmic accelerators.

description: Seit Jahrzehnten investiert nur jeder vierte bis fünfte Haushalt in Deutschland in Aktien. Mit den drei Börsengängen der Deutschen Telekom 1996 bis 2000 wurden die Deutschen in Aktienlaune versetzt. Der Kurssturz kurz nach dem zweiten Börsengang, gefolgt von Korruptionsskandalen, beendete aber die gute Aktienstimmung. Die vorliegende Studie auf Basis von SOEP-Daten zeigt, dass die Ereignisse rund um die T-Aktie zu einer anhaltend geringeren Beteiligung an den Aktienmärkten geführt hat – und zwar um rund 60 Prozent selbst noch 20 Jahre danach. Dieser Effekt ist bei Haushalten größer, die direkt in Telekom-Aktien investiert hatten. Es wurde also dauerhaft Vertrauen in Aktieninvestments zerstört, was auch einem langfristigen Vermögensaufbau im Weg stehen dürfte. Um dem entgegenzuwirken, sollten die Aufsichtsbehörden zum einen Unternehmen stärker prüfen, die Aktien an KleinanlegerInnen ausgeben, damit Fälle wie die Telekom oder jüngst Wirecard nicht weiter das Börsenvertrauen erschüttern. Zum anderen wäre es wichtig, durch finanzielle Bildung die KleinanlegerInnen in die Lage zu versetzen, Börseninvestments rationaler zu bewerten und ihre Portfolios abzusichern.

description: Nach langen coronabedingten Lockdowns erwacht die deutsche Wirtschaft nach und nach aus ihrem Winterschlaf. Da immer mehr Menschen geimpft sind und die Infektionszahlen fallen, können viele Branchen wieder auf einen normaleren Geschäftsbetrieb hoffen, allen voran die gebeutelten Dienstleistungsfirmen etwa in der Kultur- und Veranstaltungsbranche und die Reiseveranstalter. Die Industrie, die besser durch die vergangenen Monate kam als während des ersten Lockdowns im Vorjahr, wird hingegen durch die sich zuspitzende Rohstoffknappheit gebremst. Dennoch ist mit 3,2 Prozent für dieses und 4,3 Prozent für nächstes Jahr ein etwas höheres Wachstum der hiesigen Wirtschaftsleistung zu erwarten als noch im Frühjahr. Die Prognose ist aber nach wie vor mit erheblicher Unsicherheit behaftet. Ein erneut aufflammendes Infektionsgeschehen könnte genauso zu Rückschlägen führen wie eine massive Insolvenzwelle. Es könnte aber auch besser laufen, wenn die Infektionszahlen niedrig bleiben und der private Konsum schneller und nachhaltiger auf Touren kommt als gedacht.

description: We present a measurement of the scale-dependent, three-dimensional structure of the magnetic field fluctuations in inertial range solar wind turbulence with respect to a local, physically motivated coordinate system. The Alfvenic fluctuations are three-dimensionally anisotropic, with the sense of this anisotropy varying from large to small scales. At the outer scale, the magnetic field correlations are longest in the local fluctuation direction, consistent with Alfven waves. At the proton gyroscale, they are longest along the local mean field direction and shortest in the direction perpendicular to the local mean field and the local field fluctuation. The compressive fluctuations are highly elongated along the local mean field direction, although axially symmetric perpendicular to it. Their large anisotropy may explain why they are not heavily damped in the solar wind.

description: Let $G$ be a finite group and $H$ a subgroup of $G$. Each left transversal (with identity) of $H$ in $G$ has a left loop (left quasigroup with identity) structure induced by the binary operation of $G$. We say two left transversals are isomorphic if they are isomorphic with respect to the induced left loop structures. In this paper, we develop a method to calculate the number of isomorphism classes of transversals of $H$ in $G$. Also with the help of this we calculate the number of non-isomorphic left loops of a given order.
