Cahn–Hilliard-type Equations: Robust Discretization and Efficient Implementation
(2009-05-11)In this work, a robust and efficient numerical method to simulate Cahn–Hilliard-type equations is presented. The considered equations are of fourth order and contain two nonlinearities: one is the concentration-dependent ... -
Calabi-Yau Manifolds and Feynman Integral Computations: The Family of Banana Feynman Graphs
(2022-01-17)In this thesis we use geometrical and string theoretic inspired methods to compute Feynman integrals. We analyze the important family of l-loop banana Feynman graphs. For this we relate the abstract l-loop Feynman integral ... -
Calculating Corrections in F-Theory from Refined BPS Invariants and Backreacted Geometries
(2015-03-31)This thesis presents various corrections to F-theory compactifications which rely on the computation of refined Bogomol'nyi-Prasad-Sommerfield (BPS) invariants and the analysis of backreacted geometries.
Detailed ... -
Calculating Sparse and Dense Correspondences for Near-Isometric Shapes
(2018-05-29)Comparing and analysing digital models are basic techniques of geometric shape processing. These techniques have a variety of applications, such as extracting the domain knowledge contained in the growing number of digital ... -
Calibration of Terrestrial Laser Scanners: Kalibrierung terrestrischer Laserscanner
(2016)The calibration of a laser scanner is necessary to reduce systematic errors in the acquired point cloud. Furthermore, calibrating laser scanners is motivated by the need of users to access up-to-date quality information. ... -
Call Center in Deutschland: Räumliche Analyse einer standortunabhängigen Dienstleistung
(2001)Die vorliegende Arbeit setzt sich am Beispiel der für Deutschland noch relativ neuen Dienstleistung Call Center kritisch mit der Büromarktforschung und der Standortlehre von Büro betrieben auseinander. Der empirische Ansatz ... -
Can Mobile Money Facilitate Cash Transfers to Farmers and the Rural Poor in the COVID-19 Context?
(2020-06)Mobile money is widespread across Africa. The GSMA reports that around half of the 1 billion mobile money accounts worldwide were registered in Africa in 2019. In Sub-Saharan Africa (SSA) alone, mobile money transactions ... -
Can resilience be built through micro-finance tools?: A case study of coping and adaptation strategies to climate-related shocks in Piura, Peru
(2009-07-07)This study focuses on the livelihoods of rural households in the region of Piura in northern Peru, who are either farmers or livestock holders. The livelihood systems of these farmers are exposed to and vulnerable to ... -
Can the agroprocessing sector create jobs in Africa?: Evidence from Ethiopia, Ghana and Tunisia
(2022-07)This paper analyzes the potential of the agroprocessing sector to create jobs in Africa, based on the evidence from Ethiopia, Ghana and Tunisia. The analysis uses both primary qualitative data and secondary quantitative ... -
Can the halo model describe 2nd- and 3rd-order correlation functions of gravitational lensing consistently?
(2019-11-07)To understand and model the distribution of and the relation between baryonic and dark matter in the Universe is one of the key challenges in contemporary astrophysics. A well-established theoretical description is given ... -
Can we model the effect of observed sea level rise on tides?
(2018-06-07)The link between secular changes in the lunar semidiurnal ocean tide (M2) and relative sea level rise is examined based on numerical tidal modeling and the analysis of long-term sea level records from Europe, Australia, ... -
Candidate gene analysis for loci affecting sperm quality and fertility of boar
(2005)Fertility is one of the most important economical traits in swine production. Implementation of artificial insemination (AI) in swine production allowed improving selection on the boars for production traits, but at the ... -
The cannabinoid receptor 2: from mouse to human
(2015-05-13)The endocannabinoid system (ECS) regulates numerous cellular and physiological processes. Nowadays, the system comprises two G protein-coupled receptors named CB1 and CB2 receptor, and the endogenous ligands anandamide ... -
Canonical Remarks on the Motu Proprio Summorum Pontificum
(2009)In 2007, Pope Benedict XVI again allowed the Roman liturgy in its form prior to the 1970 reform. The article analyzes the new law from a formal and substantive point of view according to Church Law, and organizes the process ... -
Capturing Hand-Object Interaction and Reconstruction of Manipulated Objects
(2017-04-26)Hand motion capture with an RGB-D sensor gained recently a lot of research attention, however, even most recent approaches focus on the case of a single isolated hand. We focus instead on hands that interact with other ... -
