Large Eddy Simulation of Turbulent Premixed and Partially Premixed Combustion

In this thesis, a computational fluid dynamics (CFD) approach is used to study turbulent premixed and partially premixed combustion. The CFD approach is based on large eddy simulation (LES) in which the large-scale structures of the flow are resolved on a grid, leaving only the small-scale structures (subgrid scales) to be modeled. The combustion modelling is based on the flamelet concept in which

The Principle of Rational Decision-Making: As Applied to the Identification of Normative Conflicts in International Law

The resolution of normative conflicts is a recurring issue for the application of international law, more so now than ever before. To help lawapplying agents to justify decisions resolving a conflict between two norms,international law provides a host of different conflict rules. As several studies reveal, to apply such a conflict rule, law-applying agents often have todraw on political considerat

Individual domains of Tensin2 exhibit distinct subcellular localisations and migratory effects.

Tensins are large intracellular proteins believed to link the extracellular matrix to the cytoskeleton via integrins. Tensins are multidomain proteins consisting of homologous C1, PTPase, C2, SH2 and PTB domains. Full-length Tensin proteins can undergo cleavage inside cells, thus yielding domains in isolation that may have discrete subcellular localisations and downstream effects. We expressed dif

Tonsillar ectopia in idiopathic scoliosis: does it play a role in the pathogenesis and prognosis or is it only an incidental finding?

ABSTRACT: BACKGROUND: There is an ongoing controversy about the significance of tonsillar ectopia among patients with idiopathic scoliosis (IS). AIM: To find out if tonsillar ectopia occurs more frequently among patients with IS and if it plays any etiological or prognostic role in IS. STUDY DESIGN: Retrospective study. METHODS: Retrospective analysis of 155 consecutive spine MRIs (79 patients wit

Natural Intelligence in Artificial Creatures

What mechanisms are needed in a cognitive system, such as an animal or a robot, and how do these mechanisms interact with each other? The thesis presents a study of this problem within the field of behavior-based systems and artificial neural networks. The thesis brings together ideas from behavior-based robotics, control theory and machine learning and combines them with models from ethology, ps

A customizable pattern-based software process simulation model: design, calibration and application

Software process analysis and improvement relies heavily on empirical research. Empirical research requires measurement, experimentation, and modeling. However, whatever evidence is gained via empirical research is strongly context dependent. Thus, it is hard to combine results and capitalize upon them for the purpose of improvement in evolving development environments. The process simulationmodel

Multiple window coherence analysis of HRV power and respiratory frequency

In this paper, we evaluate the correlation estimate, based on multiple window spectrum analysis, between the respiratory center frequency and the high-frequency band of the heart- rate variability (HRV) power. One aim is to examine whether a more restricted frequency range would better capture respiratory related HR variation, especially when the HR variation is changing rapidly. The respiratory p
