Bayesian Adaptive Markov Chain Monte Carlo Estimation of Genetic Parameters
(2012-04-18)Accurate estimation of genetic parameters is crucial for an efficient genetic evaluation system. REML and Bayesian methods are commonly used for the estimation of genetic parameters. In Bayesian approach, the idea is to ... -
Challenges and opportunities of using ecological and remote sensing variables for crop pest and disease mapping
(2019-07-15)Crop pest and diseases are responsible for major economic losses in the agricultural systems in Africa resulting in food insecurity. Potential yield losses for major crops across Africa are mainly caused by pests and ... -
Conceptualising and estimating rationalised agricultural optimisation models
(2018-07-19)Computational modelling for quantitative agricultural policy assessment in the EU employs more farm level oriented approaches in recent years. This follows policy instruments that increasingly target the farm level and ... -
A Contribution to Functional Data Analysis
(2016-11-18)Functional Principal Component Analysis (FPCA) approximates a sample curve as a linear combination of orthogonal basis functions. It is often possible to describe the essential parts of the variations of functional data ... -
Contributions to Functional Data Analysis With a Focus on Points of Impact in Functional Regression
(2018-05-16)The focus of this thesis is on the estimation of an unknown number of unknown specific locations (points of impact) at which a functional predictor has a specific effect on a real valued dependent variable.
Two general ... -
Digital Filtering Algorithms for Decorrelation within Large Least Squares Problems
(2008)The GOCE (Gravity Field and steady-state Ocean Circulation Explorer) mission is dedicated to the determination of the Earth's gravity field. During the mission period of at least one year the GOCE satellite will collect ... -
Econometric Analysis of Financial Risk and Correlation
(2012-10-10)The contribution of this dissertation is threefold. First, econometric procedures to test for the occurence of asset price bubbles ex post and in real time are proposed. Real time monitoring procedures represent an additional ... -
Entwicklung eines fernerkundungsgestützten Modellverbundes zur Simulation des urban-ruralen Landnutzungswandels in Nordrhein-Westfalen
(2011-07-12)Die Veränderung der Landbedeckung und Landnutzung durch den Menschen nimmt im Zusammenhang mit der Diskussion über die Folgen des globalen Umweltwandels seit vielen Jahren eine zentrale Rolle ein. In weiten Teilen West- ... -
Essays on Large Panel Data Models
(2015-06-09)The standard panel data literature is moving from micro panels, where the cross-section dimension is large and the intertemporal sample size is small, to large panels, where both, the cross-section and the time dimension, ... -
Ein Facettenmodell zur berufsbezogenen Persönlichkeit in Situationen organisationaler Veränderungen
(2013-07-11)Das Verhalten von Mitarbeitern im Kontext organisationaler (org.) Veränderungen kann besser beschrieben und erklärt werden, wenn Personen- und Situationsvariablen gemeinsam betrachtet werden (Blickle & Schneider, 2010; ... -
Four Essays in Econometrics and Macroeconomics
(2011-09-30)Chapter 1 proposes simple and robust diagnostic tests for spatial dependence, specifically for spatial error autocorrelation and spatial lag dependence. The idea of our tests is to reformulate the testing problem such that ... -
Generating high resolution precipitation conditional on rainfall observations and satellite data
(2017-09-15)This study is part of the high resolution reanalysis project proposed for Germany and Europe (Bollmeyer et. al., 2014) within the framework of the Hans Ertel Centre for Weather Research (HErZ). The reanalysis for Germany ... -
INTERSNP: Genomweite Interaktionsanalyse mit a-priori Information
(2011-09-12)Das Ziel der Genetischen Epidemiologie ist DNA Sequenzvarianten im menschlichen Genom zu finden, die an der Entstehung von Krankheiten beteiligt sind. Genomweite Assoziationsstudien haben zur Identifikation von hunderten ... -
Ist die Versorgung zahnloser Kiefer mit konventionellen Totalprothesen heute noch zeitgemäß?
(2006)Mit dem immer umfassenderen Einsatz von Implantaten in der Zahnmedizin stellte sich die Frage, ob konventionelle Totalprothesen heute noch die zeitgemäße Versorgung zahnloser Kiefer darstellen.
Das Ziel dieser Arbeit ... -
Methods of analysis and empirical evidence of farm structural change
(2014-08-27)The dissertation aims to develop and apply new empirical methods to analyze and model farm structural change. Changes of the farm structure are not only important for the sector itself but may have broader economic, social ... -
Modeling the Dynamics of Stock Prices Using Realized Variation Measures
(2007)Recently, the availability of high-frequency financial data has opened new research directions for modeling the volatility of asset returns. In particular, building on the theory of quadratic variation, the high-frequency ... -
Modellierung der aktiven Tastsensibilität natürlicher Zähne
(2005)In der Zahnmedizin wird die feine Tastsensibilität natürlicher Zähne seit langem beschrieben. Hierzu durchgeführte Experimente dienten in erster Linie dazu, Schwellenwerte zu bestimmen. Die Modellierung der Tastsensibilität ... -
Multivariate methods and the search for single top-quark production in association with a W boson in ATLAS
(2013-05-28)This thesis describes three machine learning algorithms that can be used for physics analyses. The first is a density estimator that was derived from the Green’s function identity of the Laplace operator and is capable of ... -
Optimization of point grids in regional satellite gravity analysis using a Bayesian approach
(2020-03-25)The subject of this thesis is the global and regional gravity field determination from GOCE data using the short arc approach. The focus is on the extension of the regional method regarding an adaption of the model resolution ... -
Predicting Rules for Cancer Subtype Classification using Grammar-Based Genetic Programming on various Genomic Data Types
(2018-03-12)With the advent of high-throughput methods more genomic data then ever has been generated during the past decade. As these technologies remain cost intensive and not worthwhile for every research group, databases, such as ...
