description: Photonic lanterns are an important enabling technology for astrophotonics with a wide range of potential applications including fibre Bragg grating OH suppression, integrated photonic spectrographs and fibre scramblers for high resolution spectroscopy. The behaviour of photonic lanterns differs in several important respects from the conventional fibre systems more frequently used in astronomical instruments and a detailed understanding of this behaviour is required in order to make the most effective use of this promising technology. To this end we have undertaken a laboratory study of photonic lanterns with the aim of developing an empirical model for the mapping from input to output illumination distributions. We have measured overall transmission and near field output light distributions as a function of input angle of incidence for photonic lanterns with between 19 and 61 cores. We present the results of this work, highlight the key differences between photonic lanterns and conventional fibres, and illustrate the implications for instrument design via a case study, the design of the PRAXIS spectrograph. The empirical photonic lantern model was incorporated into an end-to-end PRAXIS performance model which was used to optimise the design parameters of the instrument. We describe the methods used and the resulting conclusions. The details of photonic lantern behaviour proved particularly important in selecting the optimum on sky field of view per fibre and in modelling of the instrument thermal background.

description: In industrial application, one of the important features for thermal insulating films in electronic devices is transparency. In order to expand the potential for industrial application, both high transparency and thermal insulating performance must be pursued. For discovery of the material systems which satisfy both properties, the extrapolative search by adaptive learning is applied combining with the previous proposed ITR model.  The reduction in thermal conductivity is related to the high density of interfaces which have high ITR rather than to the change of intrinsic thermal conductivity. The consistent thermal conductivity of TiO2 of 1.56 W/mK from 5 nm to 50 nm is observed. The selected material system of SiO2/TiO2, nanoscale-layered thin films synthesized by sputtering, show ultra-low thermal conductivity of 0.23 W/mK and high transparency (>90%, 400-780 nm). The strong substrate dependence is also found that the additional Ti2O3 phase forms as growing on Si substrate and reduces the thermal resistance as relative to the one on quartz substrate. Compared to the current transparent thermal insulating materials, aerogel or polypropylene, the proposed SiO2/TiO2 composites have higher transparency, higher robusticity, good adaptivity to electronics, and lower cost.

description: In einer Zeit, in der durch die Globalisierung und Internationalisierung die Märkte volatiler werden und Daten eine immer wichtigere Rolle spielen, werden Konzepte wie Big Data, Data Analytics oder Data Mining immer wichtiger. Unternehmen können durch die Verarbeitung und Nutzung der Daten mit den diversen Methoden der Datenanalytik wichtige Erkenntnisse gewinnen. Auch im Sales & Operations Planning Prozess sind Daten von großer Bedeutung. Dieser Prozess erzeugt und verwendet sehr viele interne und externe Daten. Die vorliegende Masterarbeit beschäftigt sich mit den Themen S&OP Prozess als zentraler Erfolgsfaktor im SCM und mit der Kernaufgabe „Prognoseerstellung“. Die Arbeit zeigt auf, dass die Ermittlung der Prognose eine der wichtigsten Aufgaben im SCM ist und als Start-punkt des S&OP Prozesses mit den unterschiedlichen Methoden aus der Datenanalytik unterstützt und optimiert werden kann. Die aktuellen Geschehnisse auf der Welt mit Covid-19, Lockdowns, Lieferkettenproblemen und internationalen Konflikten zeigen, dass wir in einem Zeitalter mit großen Unsicherheiten leben. Aus diesem Grund ist es mit all den neuen Entwicklungen und Vorhersagemethoden in der Praxis eine spannende Zeit für Prognosen. Die vielen Möglichkeiten, die Künstliche Intelligenz, Machine Learning und Data Mining bieten, welche unter dem Dachbegriff „Datenanalytik“ gesammelt wurden, liefern für die Prognose im Supply Chain Management im Vergleich zu traditionellen Methoden wesentlich bessere Ergebnisse. Nichtsdestotrotz müssen Menschen und Algorithmen Hand in Hand arbeiten, um die Prognosequalität zu steigern.

description: Startups usually have high growth ambitions but only limited resources. Therefore, they are looking for efficient and effective methods to grow their business. However, if they go interna-tional, challenging changes will likely be made if the company is not focused on the global market. The aim of this work is therefore to support startups in the internationalization of their business and to provide guidance from the beginning by using strategic marketing elements to facilitate this process. To achieve this, a qualitative method of analysis was chosen. First, a literature review was conducted on the relevant topics of a startup, strategic marketing, and internationalization. Five success factors emerged from the literature: commitment, strategy, research, marketing mix adaptation, and organization and network. These were then ana-lyzed in more detail in expert interviews. The analysis of the interview results shows that for the internationalization of startups, the commitment to internationalization and a global mindset is of great importance from the very beginning. This is because they influence all supporting and strategic marketing elements.
description: Startups haben in der Regel große Wachstumsambitionen aber nur begrenzte Ressourcen, daher suchen sie nach effizienten und effektiven Methoden, um ihr Geschäft auszubauen. Wenn sie jedoch international tätig werden und nicht auf den globalen Markt ausgerichtet sind, wird es wahrscheinlich zu herausfordernden Veränderungen kommen. Ziel dieser Arbeit ist es, Gründer bei der Internationalisierung ihres Unternehmens zu helfen und sie von An-fang an durch strategische Marketingelemente zu unterstützen, um diesen Prozess zu er-leichtern. Um dies zu erreichen, wurde eine qualitative Analysemethode gewählt. Zunächst wurde eine Literaturrecherche zu den relevanten Themen Startup, strategisches Marketing und Internationalisierung durchgeführt. Aus der Literatur ergaben sich fünf Erfolgsfaktoren: Engagement, Strategie, Forschung, Anpassung des Marketing-Mix sowie Organisation und Netzwerk. Diese wurden anschließend in Experteninterviews näher analysiert. Die Analyse der Interviewergebnisse zeigt, dass für die Internationalisierung von Startups das Engagement für die Internationalisierung und eine globale Denkweise von Anfang an von großer Bedeutung sind, denn sie beeinflussen alle unterstützenden und strategischen Marketingelemente.

description: Durch die zunehmende Homogenität von Produkten ist der technologische Fortschritt des reinen Produktes kein Alleinstellungsmerkmal mehr. Die Entwicklung datenbasierter Services bietet die Option trotzdem langfristige Wettbewerbsvorteile zu erzielen. Ein Großteil der KMU ist sich dabei in der Methodik unsicher. Es wird erörtert, wie KMU Geschäftsmodelle mit datenbasierten Services weiterentwickeln können. Mit einer qualitativen Untersuchung werden Praxiserfahrungen aufgezeigt und theoretische Thesen validiert. Die Weiterentwicklung zu einem datenbasierten Geschäftsmodell ist ein umfangreicher Prozess, der mit Chancen und Herausforderungen einhergeht. Als Herausforderung hat sich die Wahl relevanter Methoden und die Anpassung an die jeweiligen Rahmenbedingungen herausgestellt. Referenzprozesse strukturieren das Vorgehen und sollen gleichzeitig Flexibilität gewährleisten. Während des Prozesses ist die Kundenorientierung und Akzeptanz sicherzustellen. Aufgabe der Geschäftsführung ist es, die Weiterentwicklung zu fördern, Mitarbeitende einzubinden und Ressourcen bereitzustellen. Insgesamt konnte gezeigt werden, dass die Weiterentwicklung zur Veränderung der gesamten Unternehmenslogik sowie einem Paradigmenwechsel vom reinen Produktverkauf zum umfassenden Serviceangebot führt.
description: Due to the increasing homogeneity of products, the technological progress of the product itself is no longer a unique selling point. The development of data-based services offers the option of achieving longterm competitive advantages. Most SMEs are unsure about the methodology involved. The thesis discusses how SMEs can further develop business models with data-based services. A qualitative study is used to highlight practical experiences and validate theoretical theses. The further development to a data-based business model is an extensive process that is accompanied by opportunities and challenges. The choice of relevant methods and the adaptation to the respective framework conditions have turned out to be a challenge. Referencing processes structure the procedure and at the same time should ensure flexibility. During the process, customer orientation and acceptance must be ensured. It is the task of the management to promote further development, to involve employees and to provide resources. Overall, it was shown that further development leads to a change in the entire corporate logic and a paradigm shift from pure product sales to a comprehensive service offering.

We used a photon-number-resolving time-multiplexed detector based on a fiber-optical setup and a pair of avalanche photodiodes. By resorting to a germane data-pattern tomography, we assess the properties of the nonclassical light states states with unprecedented precision.

description: The complex scaling method (CSM) is a useful similarity transformation of the Schrödinger equation, in which bound-state spectra are not changed but continuum spectra are separated into resonant and non-resonant continuum ones. Because the asymptotic wave functions of the separated resonant states are regularized by the CSM, many-body resonances can be obtained by solving an eigenvalue problem with the $L^2$ basis functions. Applying this method to a system consisting of a core and valence nucleons, we investigate many-body resonant states in weakly bound nuclei very far from the stability lines. Non-resonant continuum states are also obtained with the discretized eigenvalues on the rotated branch cuts. Using these complex eigenvalues and eigenstates in CSM, we construct the extended completeness relations and Green's functions to calculate strength functions and breakup cross sections. Various kinds of theoretical calculations and comparisons with experimental data are presented.

description: Emission characteristics of quantum-dot micropillar lasers (QDMLs) are located at the intersection of nanophotonics and nonlinear dynamics, which provides an ideal platform for studying the optical interface between classical and quantum systems. In this work, a noise-induced bimodal QDML with orthogonal dual-mode outputs is modeled, and nonlinear dynamics, stochastic mode jumping and quantum statistics with the variation of stochastic noise intensity are investigated. Noise-induced effects lead to the emergence of two intensity bifurcation points for the strong and the weak mode, and the maximum output power of the strong mode becomes larger as the noise intensity increases. The anti-correlation of the two modes reaches the maximum at the second intensity bifurcation point. The dual-mode stochastic jumping frequency and effective bandwidth can exceed 100 GHz and 30 GHz under the noise-induced effect. Moreover, the noise-induced photon correlations of both modes simultaneously exhibit super-thermal bunching effects (g^{(2)}(0)\gt2) in the low injection current region. The g^{(2)}(0)-value of the strong mode can reach over 6 in the high injection current region. Photon bunching (g^{(2)}(0)\gt1) of both modes is observed over a wide range of noise intensities and injection currents. In the presence of the noise-induced effect, the photon number distribution of the strong or the weak mode is a mixture of Bose–Einstein and Poisson distributions. As the noise intensity increases, the photon number distribution of the strong mode is dominated by the Bose–Einstein distribution, and the proportion of the Poisson distribution is increased in the high injection current region, while that of the weak mode is reduced. Our results contribute to the development preparation of super-bunching quantum integrated light sources for improving the spatiotemporal resolution of quantum sensing measurements and enhancing the security of optical communication.

description: Nowadays, online marketing is becoming increasingly important not only in the B2C but also in the B2B sector, as evidenced by marketing budget expenditures. Companies pursue overarching goals involving visibility and attention from prospective customers in order to raise brand awareness and as a result, outperform increasing market competition. This begs the question of whether online marketing is appropriate for increasing brand awareness. The master´s thesis topic developed from both a personal as well as a professional perspective. Private research increased the author´s interest in the topic of online marketing. Furthermore, brands, whose level of awareness needs to be improved, are becoming a more common topic of professional debates. In this way, the research of the current master´s thesis was created. The aim of this master's thesis was to discover how online marketing can be used to increase awareness of a brand. This will be analyzed by using the brand turn to zero, which offers consulting services for B2B customers in the sustainability industry. In this context, suitable and visible online marketing channels for increasing brand awareness are to be identified. In addition to this, suitable content for the company´s own as well as paid online marketing channels need to be collected. Furthermore, the influence that online marketing has on creating brand image awareness is to be presented. Research questions are defined in order to achieve the described objectives. Within the scope of the master thesis, one main research question, as well as three sub-research questions, are to be answered based on the literature as well as the generated output resulting from the empirical part. Eight existing B2B customers of turn to zero, originating from com-mercial and industrial sectors, were interviewed in the empirical part. The interview findings were evaluated by using qualitative content analysis according to Mayring. Research results showed that targeted combinations of online marketing channels are contributing to increase brand awareness. In addition, the research succeeded in determining suitable communication content for various online marketing channels. Furthermore, the in-fluence of online marketing could be investigated more closely in terms of brand image.
Nonlinear magneto-optical response to light carrying orbital angular momentum

description: We predict a non-thermal magneto-optical effect for magnetic insulators subject to intense light carrying orbital angular momentum (OAM). Using a classical approach to second harmonic generation in non-linear media with specific symmetry properties we predict a significant nonlinear contribution to the local magnetic field triggered by light with OAM. The resulting magnetic field originates from the displacement of electrons driven by the electrical field (with amplitude $E_0$) of the spatially inhomogeneous optical pulse, modeled here as a Laguerre-Gaussian beam carrying OAM. In particular, the symmetry properties of the irradiated magnet allow for magnetic field responses which are second-order ($\sim E_0^2$) and fourth-order ($\sim E_0^4$) in electric-field strength and have opposite signs. For sufficiently high laser intensities, terms $\sim E_0^4$ dominate and generate magnetic field strengths which can be as large as several Tesla. Moreover, changing the OAM of the laser beam is shown to determine the direction of the total light-induced magnetic field, which is further utilized to study theoretically the non-thermal magnetization dynamics.

description: Quantum information processing and integrated nanophotonics require robust generation of single photon emitters on demand. In this work we demonstrate that diamond films grown by microwave plasma chemical vapour deposition on a silicon substrate host bright, narrowband single photon emitters in the visible to near infrared spectral range. The emitters possess fast lifetime, absolute photostability, and exhibit full polarization at excitation and emission. Pulsed and continuous laser excitations confirm their quantum behaviour at room temperature, while low temperature spectroscopy is done to investigate their inhomogeneous broadening. Our results advance the knowledge of solid state single photon sources and open pathways for their practical implementation in quantum communication and quantum information processing.

description: We investigate the inhomogeneous unitary Fermi gas and use the long-wavelength properties to predict the energies of small clusters of unitary fermions trapped in harmonic potentials. The large pairing gap and scale invariance place severe restrictions on the form of the density functional. We determine the relevant universal constants needed to constrain the functional from calculations of the bulk in oscillating external potentials. Comparing with exact Quantum Monte Carlo calculations, we find that the same functional correctly predicts the lack of shell closures for small clusters of fermions trapped in harmonic wells as well as their absolute energies. A rapid convergence to the bulk limit in three dimensions, where the surface to volume ratio is quite large, is demonstrated. The resulting functional can be tested experimentally, and is a key ingredient in predicting possible polarized superfluid phases and the properties of the unitary Fermi gas in optical lattices.

description: The phase space distribution of matter out to $\sim 100 \rm Mpc$ is probed by two types of observational data: galaxy redshift surveys and peculiar motions of galaxies. Important information on the process of structure formation and deviations from standard gravity have been extracted from the accumulating data. The remarkably simple Zel'dovich approximation is the basis for much of our insight into the dynamics of structure formation and the development of data analyses methods. Progress in the methodology and some recent results is reviewed.

Théorie bayesienne de la décision statistique et mesure de la radioactivité
Creators: name: Laedermann, Jean-Pascal
Publisher: name: Unknown
Year: 0

description: L'objet de ce travail est l'évaluation de l'activité de radionucléides présents à l'état de traces, par exemple dans l'environnement. Lorsque les mesures sont de courte durée, ou si les sources sont peu actives, l'analyse statistique standard ne donne plus une estimation fiable de l'activité et de son incertitude. L'introduction du concept bayesien d'a priori permet de modéliser l'information à disposition de l'observateur avant qu'il effectue la mesure. Cette information conduit à une estimation plus cohérente des grandeurs physiques recherchées. Le cadre de la théorie est tout d'abord présenté, définissant les concepts d'état, d'observation et de décision. La mesure physique est traduite par un modèle statistique qui est une probabilité de transition des états vers les observations. L'information de Fisher et celle de Shannon-Kullback sont introduites dans le but d'obtenir les a priori nécessaires au théorème de Bayes. Les modèles propres à la mesure de la radioactivité sont ensuite traités. Si l'on peut considérer l'activité comme constante, le modèle est celui de Poisson et conduit à des a priori de type gamma. Pour les grandes activités, ces deux lois se rapprochent des gaussiennes et l'on retrouve l'analyse statistique classique. Lorsque la décroissance du nombre de noyaux n'est plus négligeable, ou lors de l'évaluation de certains temps d'attente, d'autres modèles sont développés. Quelques applications sont présentées ensuite, notamment une définition cohérente des intervalles de confiance et l'estimation de l'activité de radionucléides à schéma complexe par spectrométrie gamma, où l'obtention de tout un spectre permet une analyse multidimensionnelle. Le paradigme bayesien conduit à une répartition complète et globale pour l'état du système physique mesuré. L'observateur obtient ainsi la meilleure estimation possible de l'état basée sur son modèle d'expérience et l'information préalable en sa possession.

description: Aedes aegypti mosquitoes carrying self-spreading, virus-blocking Wolbachia bacteria are being deployed to suppress dengue transmission. However, there are challenges in applying this technology in extreme environments. We introduced two Wolbachia strains into Ae. aegypti from Saudi Arabia for a release program in the hot coastal city of Jeddah. Wolbachia reduced infection and dissemination of dengue virus (DENV2) in Saudi Arabian mosquitoes and showed complete maternal transmission and cytoplasmic incompatibility. Wolbachia reduced egg hatch under a range of environmental conditions, with the Wolbachia strains showing differential thermal stability. Wolbachia effects were similar across mosquito genetic backgrounds but we found evidence of local adaptation, with Saudi Arabian mosquitoes having lower egg viability but higher adult desiccation tolerance than Australian mosquitoes. Genetic background effects will influence Wolbachia invasion dynamics, reinforcing the need to use local genotypes for mosquito release programs, particularly in extreme environments like Jeddah. Our comprehensive characterization of Wolbachia strains provides a foundation for Wolbachia-based disease interventions in harsh climates.

description: The analysis of 14 periodograms of EZ Lyn for the data spaced over 565 d in 2012--2014 (2-3.5 yr after 2010 outburst) yielded the existence of the stable signals around 100 c/d and three signals around 310 c/d, 338 c/d and 368 c/d (the corresponding periods are 864 s, 279 s, 256 s and 235 s). We interpret them as independent non-radial pulsations of the white dwarf in EZ Lyn, but a possibility that a linear combination of frequency at 100 c/d and harmonic of orbital period could produce the frequency at 368 c/d also cannot be excluded. The signal at 100 c/d was detected during the first stay in the instability strip as a transient one. The period at 338 c/d, is a known non-radial pulsation EZ Lyn entered the instability strip after the 2010 outburst. We detected the signals around 310 c/d and 368 c/d for the first time. We applied the two-dimensional least absolute shrinkage and selection operator (Lasso) analysis for the first time to explore the behavior of these signals on the scale of hours for nightly runs of observations having duration of 6-12 hr. The Lasso analysis revealed the simultaneous existence of all three frequencies (310 c/d, 338 c/d and 368 c/d) for majority of nights of observations, but with variable amplitudes and variable drifts of frequencies by 2-6 percents on a time scale of ~5-7 hr. The largest drift we detected corresponded to 17.5 s in period in ~5 hours.

description: Die stets hohen Zahlen an Kindeswohlgefährdungsfällen lenken die Aufmerksamkeit auf die Notwendigkeit professionellen Handelns zum Schutz der Kinder. Ziel der vorliegenden Arbeit ist es, die pädagogische Herangehensweise von Erziehungsberatungsstellen als Teil des Kinderschutzsystems zur Abwendung von Kindeswohlgefährdung zu untersuchen. Dazu wurden drei langjährig in Erziehungsberatungsstellen tätige Expert*innen in qualitativen Interviews befragt. Die zentralen Aussagen der Interviews wurden mittels zusammenfassender Inhaltsanalyse herausgearbeitet. Davon ausgehend wurden Verbesserungsbedarfe ermittelt und Implikationen aus pädagogischer Sicht formuliert. Relevante Ergebnisse der Analyse waren, dass das Vorgehen in Erziehungsberatungsstellen durch gesetzliche und institutionelle Vorgaben gerahmt ist, daneben ein systemischer und lösungsorientierter Beratungsansatz im Umgang mit Erziehungsberechtigten die Wahrscheinlichkeit des Beratungserfolgs steigert. Das Aufrechterhalten eines Helfer*innennetzwerks mit ausreichend geschulten Fachkräften könnte zu mehr Wachsamkeit im Sinne des Kinderschutzes führen, der Fokus sollte zukünftig auf guter Kooperation und der Qualifikation aller mit Kindern in Verbindung stehender Personen liegen, um das Erkennen von Gefährdungsfällen, die Handlungsbereitschaft und das Weiterleiten an entsprechende Fachkräfte frühzeitig zu ermöglichen.

description: Die vorliegende Masterarbeit befasst sich mit der Untersuchung von notwendigen Anforderungen an die funktionale Sicherheit von Dampf- und Kondensatsystemen. Neben einer umfassenden Literaturrecherche über erforderliche Richtlinien, harmonisierte Normen und technische Regelwerke wurde eine detaillierte Analyse eines Dampf- und Kondensatsystems durchgeführt. Es werden die Parameter Druck und Temperatur für jede Komponente des Systems betrachtet, wobei diese Parameter zum Teil auch mathematisch ermittelt werden. Anhand dieser Daten können Vorgaben bezüglich Anforderungen an eine inhärent sichere Konstruktion und an notwendige technische Sicherheitsmaßnahmen erstellt werden. Im Anschluss erfolgte die Durchführung einer HAZOP-Studie (HAZard and OPerability study), um sicherzustellen, dass das Prozessrisiko ausreichend vermindert wird. Optimal für eine gute Prozesssicherheit ist es, bereits in der Projektanfangsphase Überlegungen zu den auftretenden Drücken und Temperaturen an den Komponenten anzustellen, um diese korrekt auslegen und anfragen zu können.
description: This thesis deals with the examination of necessary requirements for the functional safety of steam and condensate systems. In addition to a thorough literature research about the necessary guidelines, harmonized standards and technical regulations, a detailed analysis of a steam and condensate system was conducted. The parameters pressure and temperature are considered for each component of the system, whereby some of these parameters are also determined mathematically. Based on this data, specifications regarding the requirements for an inherently safe construction and the necessary technical safety measures could be drawn up. This is followed by a HAZOP study (HAZard and OPerability study) to ensure that the process risk is sufficiently reduced. For good process safety, the pressures and temperatures that occur on the components should already be considered in the project's initial phase in order to be able to correctly design and request them.

description: An overview is given of recent advances in nonequilibrium statistical mechanics about the statistics of random paths and current fluctuations. Although statistics is carried out in space for equilibrium statistical mechanics, statistics is considered in time or spacetime for nonequilibrium systems. In this approach, relationships have been established between nonequilibrium properties such as the transport coefficients, the thermodynamic entropy production, or the affinities, and quantities characterizing the microscopic Hamiltonian dynamics and the chaos or fluctuations it may generate. This overview presents results for classical systems in the escape-rate formalism, stochastic processes, and open quantum systems.

description: In den vergangenen Jahren hat die digitale Transformation Abläufe, Handlungen und Entscheidungen von vielen Personen enorm verändert. In der Privatwirtschaft werden die Arbeits-weisen bereits überwiegend digital abgewickelt. Auch das Privatleben wird von immer mehr digitalen Formen geprägt. Im öffentlichen Sektor hingegen sind zwar Entwicklungen zu erkennen, der Wandel ist aber noch nicht so weit fortgeschritten wie sonst gesellschaftlich zu er-kennen ist. Das Ziel der vorliegenden Arbeit ist es, die Kernaussagen der digitalen Transformation in der öffentlichen Verwaltung aufzuzeigen und den Status Quo darzulegen. Dabei wurden die Herausforderungen genau analysiert und daraus resultierend entsprechende Handlungsempfehlungen definiert. Für die bessere Nachvollziehbarkeit wurde das Projekt „Digitales Bauverfahren“ des Vorarlberger Gemeindeverbands als Praxisbeispiel einbezogen. Daraus wurden weitere Handlungsempfehlungen entwickelt. Diese Ergebnisse können für zu-künftige Entwicklungen in der Verwaltung herangezogen werden. Sie verstehen sich auch als Beitrag für die Forschung, die damit weiter ausgeweitet wird.
description: In recent years, the digital transformation has changed the processes, actions and decisions of many people enormously. In the private sector, working methods are already mostly managed digitally. Private life is also being changed by more and more digital possibilities. In the public sector, on the other hand, developments can be seen, but the change is not yet as far advanced as might otherwise be realized. The aim of this paper is to highlight the core state-ments of digital transformation in public administration and to present the status quo. Due to this, the challenges have been analyzed in detail and recommendations for action were defined as a result. For better comprehensibility, the project ”Digitales Bauverfahren“ of the Vorarlberger Gemeindeverband (Association of Communities) was included as a practical example. Recommendations for action were also derived from this. These results can be used for further developments in the administration and thus the research can be expanded.

description: Bezugnehmend auf die immer strenger werdenden Abgasnormen müssen effizientere und emissionsärmere Antriebssysteme entwickelt werden. Ein Ansatz hierfür ist die Verwendung von Brennstoffzellen als Hilfsaggregate in Automobilen. Da Experimente mit Brennstoffzellen komplex, teuer und meistens auch gefährlich sind, wird ein Fokus auf die Simulation gelegt. Im Rahmen dieser Arbeit werden dynamische Modelle der Komponenten Reformer und Stack einer Festkörperbrennstoffzelle erstellt. Zu Beginn werden die Grundlagen von Brennstoffzellen und Reformern besprochen. In weiterer Folge wird die Modellierung anhand physikalischer und mathematischer Ansätze und die Validierung dieser Modelle vorgestellt. Dabei werden beim Reformermodell die unterschiedlichen Reformierungsarten Dampfreformierung, partielle Oxidation und autotherme Reformierung sowie die Verwendung von unterschiedlichen Brennstoffen berücksichtigt. Beim Brennstoffzellenstackmodell können die drei Strömungskonfigurationen Gleich-, Gegen- und Wechselstrom simuliert werden. Durch Kalibrierung der Modelle mit Benchmarkmodellen kann die Gültigkeit überprüft werden. Als Ergebnisse dieser kalibrierten Modelle können die Austrittstemperatur und die Austrittsgaszusammensetzung genannt werden. Mithilfe dieser wird die zukünftige modellbasierte Entwicklung von Steuerungsalgorithmen ermöglicht.
description: Regarding the even increasing economic and environmental requirements in the automotive industry, new clean and efficient drive systems have to be developed. One approach is to use fuel cell systems as an auxiliary power unit to reduce the environmental impact. Because experiments on fuel cells are complex, expensive and partially dangerous, the emphasis is focused on the simulation of fuel cells. The aim of this thesis is the development of dynamic models for the two main components of a solid oxide fuel cell system, i.e. the reformer and the fuel cell stack itself. At the beginning the basics of reformers and fuel cells are introduced. Furthermore, the modeling based on mathematical and physical approaches and their validation is explained in detail. The reformer model implements three reforming processes: steam reforming, catalytic partial oxidation and the autothermic reforming. It includes the reforming of different fuels like ethanol, methane and methanol. The fuel cell stack model implements the flow configurations referred to co-, counter- and crossflow. By calibrating the models with comparison to other models, their validity has been proved. As a result, the outlet temperature of the reformer and the stack is mentioned. Moreover, the outlet gas composition and the process variables of both components are obtained. Based on these results the model based calibration of control algorithms can be realized.

Contribution to the Development of the LHCb Vertex Locator Readout Electronics

description: L'expérience LHCb sera installée sur le futur accélérateur LHC du CERN. LHCb est un spectromètre à un bras consacré aux mesures de précision de la violation CP et à l'étude des désintégrations rares des particules qui contiennent un quark b. Actuellement LHCb se trouve dans la phase finale de recherche et développement et de conception. La construction a déjà commencé pour l'aimant et les calorimètres. Dans le Modèle Standard, la violation CP est causée par une phase complexe dans la matrice 3x3 CKM (Cabibbo-Kobayashi-Maskawa) de mélange des quarks. L'expérience LHCb compte utiliser les mesons B pour tester l'unitarité de cette matrice, en mesurant de diverses manières indépendantes tous les angles et côtés du "triangle d'unitarité". Cela permettra de surdéterminer le modèle et, peut-être, de mettre en évidence des incohérences qui seraient le signal de l'existence d'une physique au-delà du Modèle Standard. La reconstruction du vertex de désintégration des particules est une condition fondamentale pour l'expérience LHCb. La présence d'un vertex secondaire déplacé est une signature de la désintégration de particules avec un quark b. Cette signature est utilisée dans le trigger topologique du LHCb. Le Vertex Locator (VeLo) doit fournir des mesures précises de coordonnées de passage des traces près de la région d'interaction. Ces points sont ensuite utilisés pour reconstruire les trajectoires des particules et l'identification des vertices secondaires et la mesure des temps de vie des hadrons avec quark b. L'électronique du VeLo est une partie essentielle du système d'acquisition de données et doit se conformer aux spécifications de l'électronique de LHCb. La conception des circuits doit maximiser le rapport signal/bruit pour obtenir la meilleure performance de reconstruction des traces dans le détecteur. L'électronique, conçue en parallèle avec le développement du détecteur de silicium, a parcouru plusieurs phases de "prototyping" décrites dans cette thèse.

description: Small angle neutron and x-ray scattering methods are used to investigate the structure of dilute suspensions of two different ferrofluid systems dispersed in soft polyacrylamide hydrogels. It is found that the particles in the fluid are fractal aggregates composed of smaller particles of radius ca. 5 nm. The fractal dimension is strongly dependent on sample, taking the value 1.7 in the first sample and 2.9 in the second sample. In the presence of a magnetic field the aggregates orient, but are restricted in both their translational and rotational freedom. The effect of the gel elasticity is treated as a hindrance to the orientation process.
