Mining Frequent Itemsets from Transactional Data Streams with Probabilistic Error Bounds
(2020-05-27)Frequent itemset mining is a classical data mining task with a broad range of applications, including fraud discovery and product recommendation. The enumeration of frequent itemsets has two main benefits for such ... -
Development and Application of London Dispersion Corrections for Electronic Structure Methods
(2020-05-19)Mean-field electronic structure methods like Hartree–Fock ( HF ) or Kohn–Sham ( KS ) Density Functional Theory ( DFT ) do not account for long-range correlation effects and consequently ... -
Network effects of eslicarbazepine in the hippocampus
(2020-05-18)Nearly 50 million people worldwide suffer from epilepsy, with 1/3 of the patients remaining without seizure control. This high number emphasizes the importance to develop new anti-epileptic drugs (AEDs) and to understand ... -
Geriatrische Medikationsanalyse für Pflegeheimbewohner durch öffentliche Apotheken
(2020-05-18)Pflegeheimbewohner sind häufig von Polymedikation und damit einhergehenden arzneimittelbezogenen Problemen (ABP) betroffen. Medikationsanalysen können die Angemessenheit der Medikation bei Älteren verbessern. Mit der ... -
Λ(1405) photoproduction with the BGO-OD experiment
(2020-05-14)The Λ(1405) has been considered for many years a candidate for an unconventional hadronic state. Being difficult to understand within the framework of a three valence quark, constituent quark model, models explicitly ... -
Sedimentation of particle suspensions in Stokes flows
(2020-05-14)In this thesis, we consider problems arising from the physical phenomenon of particle sedimentation. We focus on non-Brownian particles in fluids at zero Reynolds number. Microscopically, the particle system is described ... -
Quantum simulation of strongly-correlated two-dimensional fermions in optical lattices
(2020-05-12)In this thesis, I present the experimental realisation of the two-dimensional Hubbard model with ultracold fermionic Potassium-40 atoms in optical lattices. By tuning the dimensionality, kinetic and interaction in the ... -
Functional Integration of Floral Plant Traits: Shape and Symmetry, Optical Signal, Reward and Reproduction in the Angiosperm Flower
(2020-05-12)Pollination syndromes represent groups of floral phenotypes that have originated and diversified in interaction with biotic and abiotic pollen vectors. Plant trait pattern that constitute respective syndromes have been ... -
Untersuchungen zur Synthese und Reaktivität 1,3-ambiphiler Phosphinidenoidkomplexe mit einem P-O-Element-Strukturmotiv
(2020-05-05)Die Arbeit behandelt Untersuchungen zur Darstellung neuartiger 1,3-ambiphiler Phosphinidenoidkomplexe, welche neben dem Phosphoratom als Donorfunktion entweder ein Bor- oder ein Siliziumatom als Akzeptorfunktion aufweisen. ... -
Theoretical Analysis of Hierarchical Clustering and the Shadow Vertex Algorithm
(2020-05-05)Agglomerative clustering (AC) is a very popular greedy method for computing hierarchical clusterings in practice, yet its theoretical properties have been studied relatively little. We consider AC with respect to the most ... -
Federated Query Processing over Heterogeneous Data Sources in a Semantic Data Lake
(2020-05-05)Data provides the basis for emerging scientific and interdisciplinary data-centric applications with the potential of improving the quality of life for citizens. Big Data plays an important role in promoting both manufacturing ... -
Diffusions on Wasserstein Spaces
(2020-05-05)We construct a canonical diffusion process on the space of probability measures over a closed Riemannian manifold, with invariant measure the Dirichlet–Ferguson measure. Together with a brief survey of the relevant literature, ... -
Linked Research on the Decentralised Web
(2020-05-05)This thesis is about research communication in the context of the Web. I analyse literature which reveals how researchers are making use of Web technologies for knowledge dissemination, as well as how individuals are ... -
Modeling water availability for smallholder farming in inland valleys under climate and land use / land cover change in Dano, Burkina Faso
(2020-05-05)Effective water management in inland valley catchments is crucial for adaptation to the adverse impact of climate change and land use and land cover change (LULCC) on smallholder farming systems, poverty reduction, attaining ... -
Various Aspects of Astroparticle Physics and the Implications for Dark Matter Searches
(2020-05-04)Cosmic rays offer an opportunity to search for dark matter, if the latter decays or annihilates into standard model particles. In the first part of this work, we address an excess that was claimed to be seen in the cosmic ...
