DAHP Synthasen aus Pilzen
(2002-07-09)The first step of the biosynthesis of the aromatic amino acids is the condensation of erythrose-4-phosphate and phosphoenolpyruvate to 3-deoxy-D-arabino-heptuloso-nate 7-phosphate. This ... -
Darstellung bor- und phosphorhaltiger Ringe durch Reaktionen von Halogenboranen und -phosphanen mit Bis(tert.-butyl-methyl)ketazin
(2004-10-22)The first part of this thesis refers to the reactions of boroles, especially substitutions of remaining halogens and dehydrohalogenation reactions. The second part deals with similarities ... -
Darstellung magmatischer Prozesse über die U-Th Ungleichgewichts-Methode. Vergleich von zwei andinen magmatichen Systemen: Vulkan El Misti (Südperu) versus des Taapaca Vulkankomplexes (Nordchile).
(2009-03-10)El Misti Volcano (South Peru) and Taapaca Volcanic Complex (North Chile) both located in the Central Andean Volcanic Zone in South America have been studied in order to place constrains on ... -
Darstellung neuer Organometallhalogenide mit Elementen der 13. und 14. Gruppe des Periodensystems und Versuche zur Synthese von Organogermanolen
(2003-08-18)The first part of the thesis is focused on the synthesis and structural characterisation of organometal halides of group 13 of the periodic system. Fluorination of [MeAlN(2,6-i-Pr2C6H3)]3 ... -
Data Analysis of Musical Timeseries
(2024-01-08)Music, despite its ubiquitous familiarity, is surprisingly hard to define. Should one consider its acoustic features, the mechanics by which it is produced and performed, as well as the cultural norms attached to them, ... -
Data Compression for Helioseismology
(2015-10-22)Efficient data compression will play an important role for several upcoming and planned space missions involving helioseismology, such as Solar Orbiter. Solar Orbiter, to be launched in October 2018, will be the next ... -
Data driven analysis of brain activity and functional connectivity in fMRI
(2003-12-18)In this thesis the perspectives of statistical and graph-theoretical methods for the analysis of fMRI data are investigated. This involves preprocessing, extraction of components, functional ... -
Data intensive ATLAS workflows in the Cloud
(2018-06-06)Large physics experiments, such as ATLAS, have participating physicists and institutes all over the Globe. Nowadays, physics analyses are performed on data that is stored thousands of kilometres away. This is possible due ... -
Data Protection and Data Security Concept for Medical Applications in a Grid Computing Environment
(2008-11-20)This thesis is addressing the authorization problem in healthgrid environments, which is still an obstacle in front of using grid computing for medical applications. Current grid authorization ... -
Data Quality Bench-Marking for High Resolution Bragg Data
(2015-03-05)The thesis deals with data quality bench-marking for high resolution Bragg data. It compares and evaluates Bragg data from various radiation sources and different detection types. Two different small molecules containing ... -
Data-driven goodness-of-fit tests
(2007-08-22)The thesis consists of the two main parts.In the first part, we consider testing statistical hypotheses about densities of signals in deconvolution models. A new approach to this problem is proposed. ... -
Data-driven modelling of non-linear systems by means of artificial neural network hybrids
(2021-04-16)In the natural sciences, theory and experiment are in permanent interaction with each other. Experimental data provide impulses for new theories and theories suggest new experimental set-ups. Earlier, these two areas had ... -
Data-Driven Network Analysis and Applications
(2016-01-08)Data is critical for scientific research and engineering systems. However, data collection procedures are often subject to high cost or heavy loss rate. It is challenging to accurately estimate missing or unobserved data ... -

(2002-04-18)A data base system (P.A.S.T) for processing and interpreting palynological data from the Palaeogene of Central Europe - application to diversity studiesThe first part of the thesis presents an outline ... -
Decaying Dark Matter models at colliders
(2016-04-07)After the first run of LHC, no signal of new physics has been found in terms of the DM motivated channels containing missing energy. Even though the next LHC run could still detect a WIMP-like signal, especially from the ... -
Decentralized Network Based Mobility Management: Framework, System Design and Evaluation
(2011-09-23)The handling of mobile nodes in the Internet has always been challenging since the Internet Protocol (IP) by design assumes that a network interface has an identifier that stays fixed at ... -
Deciphering the Catalytic Mechanism of the Zn Enzyme Glutaminyl Cyclase and the Deduction of Transition-State Analog Inhibitors
(2015-07-20)Zn(II)-dependent glutaminyl cyclase (QC) converts N-terminal glutamine or glutamate residues of peptides and proteins. The reaction product is in both cases N-terminal pyroglutamic acid (pyroGlu). In animals the glutaminyl ... -
Deciphering the genetic background of quantitative traits using machine learning and bioinformatics frameworks
