Vertriebsseitige Herausforderungen bei industriellen Betreibermodellen: eine integrierte Betrachtung der Anbieter- und Nachfragerperspektive See

Industrielle Betreibermodelle sind in den vergangenen Jahren in den Fokus des praktischen und wissenschaftlichen Diskurses gerückt, da mit ihnen umfassende Potenziale für Anbieter und Nachfrager realisiert werden können. Gleichzeitig konnten in übergeordneten Forschungsgebieten bereits vielfältige Erkenntnisse zum Vertrieb komplexer Produkt- Dienstleistungsbündel und industrieller Problemlösungen generiert werden. Allerdings sind industrielle Betreibermodelle hochgradig individuelle Geschäfts...

Measurement of 𝘾𝙋 violation in the decay 𝘽𝟬 → 𝘿∓𝞹± at the LHCb experiment See

In dieser Arbeit wird eine Messung der CP-Asymmetrien Sf und S_f ̅ in B^0→D^∓ π^±-Zerfällen präsentiert. Der analysierte Datensatz enthält dabei Ereignisse aus Proton-Proton-Kollisionen bei Schwerpunktsenergien von 7 und 8 TeV, die in den Jahren 2011 und 2012 vom LHCb-Detektor aufgenommen wurden und entspricht einer integrierten Luminosität von 3 fb-1. Die CP-Asymmetrien sind gemessen als Sf=0.058±0.020(stat.)±0.011(syst.), S_f ̅ =0.038±0.020(stat.)±0.007(syst.). Diese Ergebnisse sind pr...

Das Potenzial von ökonomischer Bewertung und Partizipation für die Planung grüner Infrastruktur See

Green and open spaces are important components of green infrastructure. They offer a range of different ecosystem services society benefits from. Due to ongoing urbanisation and densification processes many urban and peri-urban green and open spaces disappear or degrade in quantity and quality, with negative impact on their ecosystems. The decline of the ecological functions of nature and landscape also weakens their social and economic merits, which are especially important for society. Henc...

Barkhausen noise assessment of the surface conditions due to deep hole drilling and their influence on the fatigue behaviour of AISI 4140 See

In many technical fields, high-strength steels like AISI 4140 are commonly used for highly dynamically loaded parts. Increasing demands on weight, performance and efficiency of the automotive industry lead to increasing demands on material properties. For surface conditioning, optimised machining processes are capable of improving the fatigue performance without increasing the production cost significantly. This paper compares the influence of three different sulphur contents and three d...

Entwicklung eines Back-End-Prozesses für eine vollständig CMOS-kompatible Integration nanoskaliger Drucksensoren See

Bedingt durch die stetige Nachfrage einer immerwährenden Miniaturisierung von mikro-mechanischen Systemen muss der zur Integration erforderliche Platz eines solchen Systems weiter reduziert werden. Ein bekannter Ansatz hierfür ist der sogenannte System-On-a-Chip Ansatz, bei dem alle Elemente des Systems monolithisch integriert werden. Hierbei wird die erforderliche Substratfläche zweidimensional optimal ausgenutzt, während die dritte Dimension oftmals unberücksichtigt bleibt. Dies trifft insb...

Learning algorithms, and current developments – banking at the crossroads See

Since the 2008 financial crisis much discourse questioned the relevance of the banking industry to society; in particular given sovereign bailouts of failed banks. Such questions provide the context in which this thesis covers four key topics for wholesale banking in the future. Firstly, in relation to efficiency improvements in the wholesale banking model and promotion of market liquidity, ‘Machine Learning’ techniques were applied to predict the behaviour of wholesale customers in addition ...

Survival models with selection of genomic covariates in heterogeneous cancer studies See

Building a risk prediction model for a specific subgroup of patients based on high-dimensional molecular measurements such as gene expression data is an important current field of biostatistical research. Major objectives in modeling high-dimensional data are good prediction performance and finding a subset of covariates that are truly relevant to the outcome (here: time-to-event endpoint). The latter requires variable selection to obtain a sparse, interpretable model solution. In this thes...

Questionnaire Monitoring Behavior in Schools (QMBS). Description of the scale „Questionnaire Monitoring Behavior in Schools“ (QMBS) in English and German language See

We developed a multidimensional Direct Behavior Rating (DBR-MIS) with different dimensions for externalizing, internalizing, and positive behaviors that are relevant in daily classroom situations. Along the lines of other established screening tools (i.e., the Strengths and Difficulties Questionnaire (SDQ); Goodman, 1997, 2001; Voss & Gebhardt, 2017), we created two for dimensions for externalizing problems (disruptive behavior (DB); academic engagement problems (AEP)), two dimensions for int...

Land use and social rights See

This thesis studies the themes of land use and social rights with special reference to the urban village, which is a special phenomenon in city-expansion in contemporary China. By conducting an extensive review of literatures on urban villages and boundary studies, the author studies land use and social rights from the perspective of boundary. The author also emphasizes boundary-making as a social construction process, which involves different stakeholders in this “game”. Further, the author ...

The effects of public inputs, goods and services on households’ and firms’ location decision See

The aim of this dissertation is to contribute to the discussion on the effects of public inputs, goods and services (PIGS) on households’ and firms’ location decision. This work contributes to the debate providing greater insights on the empirical effects of PIGS on spatial mobility using detailed data for Germany. Chapter 2 assesses the short and long run impact of local grammar schools on employment in East German municipalities and finds evidence in favor of a 9% decrease in residential ...

Prediction of Achievable Energy Deposition for Vaporizing Foil Actuators See

A novel iterative analytic approach allowing for the prediction of energy deposition into Vaporizing Foil Actuators (VFA) is presented. Besides the process parameters of actuator geometry and pulse generator configuration, it takes into account the energy dependence of the resistivity as well as the rate dependence of the achievable energy deposition. This rate dependency is found experimentally for aluminum foils and subsequently used in the modeling. With an average deviation of less than 1...

Steuerungsmechanismen zur Sicherstellung der Medienbildung in Kindertagesstätten See

Für die mediale Aneignung von Welt benötigen Kinder vielfältige Möglichkeiten zur Auseinandersetzung. Vor dem Hintergrund des Bildungsverständnisses der Frühpädagogik (Schäfer 2011) und der Notwendigkeit, Kindern schon vor Schuleintritt die Entwicklung der Medienkompetenz (Baacke 1996) oder – bei stärkerer Anbindung an den erweiterten Textbegriff der Deutschdidaktik (Kallmeyer et al. 1974) – einer basalen „Digital Literacy“ (Kontovourki et al. 2017) zu ermöglichen, beschäftigt sich die vorlie...

Output-sensitive complexity of multiobjective combinatorial optimization with an application to the multiobjective shortest path problem See

In this thesis, we are concerned with multiobjective combinatorial optimization (MOCO) problems. We attempt to fill the gap between theory and practice, which comes from the lack of a deep complexity theory for MOCO problems. In a first part, we consider a complexity notion for multiobjective optimization problems which derives from output-sensitive complexity. The primary goal of such a complexity notion is to classify problems into easy and hard problems. We show that the multiobjectiv...
