Studies towards controlling selectivity in Minisci reactions
… In the first part of the thesis, the effects of solvent and achiral Brønsted acid catalysis on regioselectivity in the Minisci-type addition of N-acyl α-amino radicals to quinolines was investigated. Two sets of conditions, that favour either the C2- or C4-position, were identified and …

Viscous streaming-enhanced inertial particle transport
… wide range of tasks is viscous streaming, a non-linear effect characteristic of the scales above. In this thesis, we first show that numerical simulations based on the Remeshed Vortex Method (RVM) can accurately and efficiently capture viscous streaming dynamics. We test this algorithm on a …

Corporate governance, firm performance, and executive compensation : evidence from China
… in China. Therefore, we attempt to explore the effects of political connections of their ultimate controllers on corporate governance mechanism, on firm performance, and on executive compensation in China. Our findings indicate a dysfunctional corporate governance system in China, which cannot …

Three Essays on Environmental Economics and International Trade
… turned to evaluate different and countervailing effects of international trade (scale, technique and composition effects) on the environment in Chinese provinces. In the last essay, we investigate empirically the impacts of international trade on China’s sustainable development using Chinese …

Mitigating timing noise in ADCs through digital post-processing
… times, known as jitter, or timing noise, has a non-linear, time-varying and input-dependent effect on the sample values, as opposed to the additive noise usually considered. At present, the error due to jitter is minimized through the use of low-jitter clocks, limiting the suitability of such …

Mechanical Modelling of single and collective cells behavior
… the modelling has been enriched considering the non-linear effect of the prestress, induced in protein filaments during cell adhesion and in the cell membrane (with a simple multiscale scheme that incorporates finite elasticity and a 3-D circus tent-like model), on the overall cell stiffness and …

Evaluation of the impact of reproductive technologies on the genetic improvement and profit of pig production systems
… technique and semen preparation had a non-linear effect on profit. A subsequent study evaluated the impact of boar selection strategies including four semen traits in addition to standard paternal and maternal traits on genetic improvement and profit of the enterprise. A first-in-kind …

Constraining dark energy using real and mock galaxy surveys
… potential on the CMB (the integrated Sachs-Wolfe effect). We use semi-analytical galaxy formation models implemented in N-body simulations to build mock galaxy catalogues which are well suited for use in conjunction with large photometric surveys. Using mock catalogues, we predict that Pan-STARRS1 …
