Model Building and Phenomenology in Supersymmetry
Kim, Jong Soo (2008)<p>Supersymmetry (SUSY) stabilizes the hierarchy between the electroweak scale and the scale of grand unified theories (GUT) or the Planck scale. The simplest supersymmetric extension of the SM, the minimal supersymmetric ... -
Model electrodes for electrocatalysis: Ultrathin palladium films on Pt(111)
Arenz, Matthias (2002)In this work the electrocatalytic activity of a bimetallic model catalyst, a pseudomorphic monolayer of palladium supported on Pt(111), is characterized. The reactions probed, which are the carbon monoxide oxidation reaction, ... -
Model electrodes for the electrooxidation of simple alcohols: a DEMS study
Abd-El-Salehin, Abd-El-Aziz Ali Abd-El-Latif (2011-09-12)<p>Pt is considered as a model for fuel cell electrocatalysts. In the present thesis, I stud-ied the electrooxidation mechanisms of methanol (chapter 3) and ethanol (chapter 4) on different Pt surfaces, using a dual ... -
Model-based formulation of amorphous solid dispersions made by hot-melt extrusion
Bochmann, Esther Sophia (2019-08-21)Regarding hot-melt extrusion in early pharmaceutical formulation and process development, techniques and procedures are needed to simplify the application of hot-melt extrusion (HME) and to decrease the effort in terms of ... -
Model-based Source Partitioning of Eddy Covariance Flux Measurements
Klosterhalfen, Anne (2019-05-03)Terrestrial ecosystems constantly exchange momentum, energy, and mass (e.g., water vapor, CO<sub>2</sub>) with the atmosphere above. This exchange is commonly measured with a micrometeorological technique, the eddy covariance ... -
Modeling and Simulation of cracks and fractures with peridynamics in brittle materials
Diehl, Patrick (2017-04-24)Today, ceramic materials are an essential component of batteries for electric cars. One key feature of this kind of battery is the safety of the ceramic core. Here, the precise approximation of the evolution of damage after ... -
Modeling climate and land use change impacts on water resources and soil erosion in the Dano catchment (Burkina Faso, West Africa)
Op de Hipt, Felix (2018-07-11)The study assesses the effect of climate and land use change on water resources and soil ero-sion in the Dano catchment, Burkina Faso. Field measurements and derived process under-standing are complemented by a physically ... -
Modeling climate and land use change impacts on water resources in the dano catchment (Burkina Faso, West africa)
Yira, Yacouba (2016-12-20)This study investigated the impacts of climate and land use changes on water resources in the Dano catchment combining hydrological processes understanding, hydrological simulations and climate and land use scenarios ... -
Modeling Gas-Grain Chemistry in Dark Cloud Conditions
Du, Fujun (2012-08-23)I first wrote a gas phase chemical code, which solves for the gas phase composition of an interstellar cloud as a function of time. We used this code to study the abundance ratios between the H<sub>3</sub><sup>+</sup> ... -
Modeling hydrological processes in a semi-arid mountainous catchment at the regional scale
Busche, Henning Georg Kaspar (2013-04-02)In the Upper Drâa Valley (14,988 km<sup>2</sup>) on the southern slopes of the Moroccan High Atlas Mountains, a highly variable precipitation and large evaporation losses cause major water availability problems. The combined ... -
Modeling Linearly and non-Linearly Dependent Simulation Input Data
Nassaj, Feras (2010-08-04)Input modeling software tries to fit standard probability distributions to data assuming that the data are independent. However, the input environment can generate correlated data. Ignoring the correlations might lead to ... -
Modeling of Ewaso Narok floodplain: a study of the hydrochemistry and hydrogeology in a data scarce environment
Hashweh, Layla (2023-03-07)The Ewaso Narok wetland, a floodplain intensively used for grazing, drinking, and agriculture, is part of Kenya’s largest drainage basin. This study lies within the water and food security scope, in affiliation with the ... -
Modeling of the Near Infrared Emission From the Peculiar B[e]-Star MWC349
Kraus, Michaela (2000)The aim of this thesis is to investigate the first overtone band emission of CO from the peculiar B[e] star MWC 349. With the United Kingdom Infrared Telescope (UKIRT) in Hawaii, low resolution observations were made to ... -
Modeling of vegetation dynamics and its contribution to the water balance in semi-arid lands of West Africa
Tia, Lazare (2008)Initially considered as merely a spectator in the functioning of the Earth system, vegetation is now recognized as an important component of the global climate system through its control of energy fluxes over substantial ... -
Modeling ripple formation
Küpper, Michael (2004)The aim of this thesis was to approach the problem of ripple formation by a model which describes the phenomenon on a macroscopic scale and does not incorporate the detailed dynamics of the fluid flow field. We developed ... -
