MR-Phasenbilder ultraschallinduzierter Verschiebungsfelder an Brustläsionen
Wild, Judith Charlotte (2017-09-15)In dieser Arbeit wurde eine Methode erforscht, die die Uktraschalstrahlungskraft mit der MRT kombiniert.
Durch die Schallstrahlungskraft werden im Gewebe Verschiebungen hervorgerufen. Diese lieferten einen Kontrast ... -
Die MSINDO-sCIS- und MSINDO-UCIS-Methoden: Verfahren zur Berechnung von Eigenschaften angeregter Zustande in Molekülen und periodischen Systemen mit einem semiempirischen Ansatz
Gadaczek, Immanuel Patrick (2013-01-04)In dieser Arbeit wird ein effizientes Verfahren zur Berechnung angeregter Zustände großer molekularer und periodischer Systeme entwickelt und auf ausgewählte Systeme angewendet. Im Rahmen der CIS-Näherung werden nur ... -
The Mukai system of rank two and genus two
Hellmann, Isabell (2020-11-19)We study the Mukai system $M rightarrow mathbb{P}^5$ of rank two and genus two from three different points of view. We compute the degrees and multiplicities of the irreducible components of the fibers over non-reduced ... -
Multi Robot Intruder Search
Moors, Mark (2009-02-16)The aim of this work is the development and analysis of methods and algorithms to allow a multi robot system to cooperatively search a closed, 2-dimensional environment for a human intruder. The underlying problem corresponds ... -
A multi-agent system for simulating land-use and land-cover change in the Atankwidi catchment of Upper East Ghana
Schindler, Julia (2010-01-27)Land-use and land-cover change (LUCC), which is a general term for the human modification of the Earth’s terrestrial surface, increasingly gains attention in the scientific community, due to its vast global extent and the ... -
Multi-Chip-Modul-Entwicklung für den ATLAS-Pixeldetektor: Analyse der Front-End-Chip-Elektronik in strahlenharter 0,25-µm-Technologie sowie Entwicklung und Realisierung eines Serial-Powering-Konzeptes
Stockmanns, Tobias (2004)The innermost layer of the ATLAS tracking system is a silicon pixel detector. The use of radiation tolerant components is mandatory due to the harsh radiation environment. The smallest independent component of the pixel ... -
Multi-faceted Structure-Activity Relationship Analysis Using Graphical Representations
Iyer, Preeti Ramesh (2014-02-18)A core focus in medicinal chemistry is the interpretation of structure-activity relationships (SARs) of small molecules. SAR analysis is typically carried out on a case-by-case basis for compound sets that share activity ... -
Multi-frequency analysis of intraday variable radio sources
Cimò, Giuseppe (2003)Active Galactic Nuclei (AGN) are known to show significant flux density variability across the whole electromagnetic spectrum on a wide range of time scales, from years to less than one day. In the radio regime, variability ... -
Multi-Frequency Study of the NVSS Foreground Sources in the Cosmic Background Imager Fields
Angelakis, Emmanouil (2007)The point radio sources comprise one amongst the major contaminants of the Cosmic Microwave Background radiation. Consequently, they possess a significant potential for causing severe distortion of the information imprinted ... -
Multi-scale chiral dynamics
Bruns, Peter Christian (2009-07-21)In this work, we examine two possible extensions of the low-energy effective field theory of quantum chromodynamics (QCD), called chiral perturbation theory (ChPT). Both those extensions are related to the presence of ... -
Multi-scale modeling of sediment and nutrient flow dynamics in the Ouémé catchment (Benin) - towards an assessment of global change effects on soil degradation and water quality
Bossa, Yaovi Aymar (2012-09-24)Beyond aspects such as the quantification of soil and water degradation, this work investigated impacts of differences in the input boundary conditions (e.g. soil map, land use) on the performance of the Soil and Water ... -
Multi-scale modeling of water resources in a tropical inland valley and a tropical floodplain catchment in East Africa
Gabiri, Geofrey (2019-02-12)This study investigated the dynamics of hydrological processes at the wetland-catchment scale through field scale-based analysis, point scale modeling using Hydrus-1D model along a floodplain transect in Tanzania and ... -
Multi-scale targeting of land degradation in northern Uzbekistan using satellite remote sensing
Dubovyk, Olena (2013-11-13)Advancing land degradation (LD) in the irrigated agro-ecosystems of Uzbekistan hinders sustainable development of this predominantly agricultural country. Until now, only sparse and out-of-date information on current land ... -
Multi-stage Micropattern Gaseous Detectors for the ALICE TPC Upgrade - Studying and Modelling Charge Transfer and Energy Resolution
Ratza, Viktor (2020-06-23)With the upgrade of the LHC (Large Hadron Collider) at CERN, the interaction rate of ALICE (A Large Ion Collider Experiment) will be increased up to 50 kHz for Pb-Pb collisions. Thus the gated and rate-limited readout ... -
Multi-taxic palaeohistological analyses of vertebrates originating from the Upper Triassic at Krasiejów (SW Poland) and an assessment of growth patterns in comparative taxa
Teschner, Elżbieta M. (2023-03-29)Palaeohistology is a good source of information about the biology of extinct animals as it provides insight into skeletochronology, metabolic rate or mode of life. The Polish Krasiejów locality recovers a unique Upper ... -
