6. The Effect of Different Perturbations on the Stability Analysis of Light Water Reactors
Abstract : Neutron noise analysis techniques are studied and developed, with primary useof determining the stability of Boiling Water Reactors (BWRs). In particular, the role ofa specific perturbation prevailing in Light Water Reactors, the propagating densityperturbation, in the stability of BWRs and on the noise field of LWRs in general, isinvestigated by considering three topics.

7. PET in Heart Failure - Methods and Applications
Abstract : Positron Emission Tomography (PET) permits regional myocardial perfusion, fibrosis and oxidative metabolism to be non-invasively quantified with radioactive tracers such as [15O]-water and [1-11C]-acetate. PET is an established research tool in congestive heart failure (CHF), a major cause of morbidity and mortality. READ MORE

8. Mathematical and Physical Simulations of BOF Converters
Abstract : The purpose of this study is to develop mathematical models to explore the mixing and its related phenomena in converter bath. Specifically, first, a mathematical model of a physical model converter, which was scaled down to 1/6th of a 30 t vessel, was developed in this study. READ MORE

9. Optimization of Chemical Kinetic Mechanisms and Numerical Simulations of Industrial Gas Turbine Burners
Abstract : Increasing demands on environmentally friendly energy conversion indicate that pollutants need to be reduced. Computational Fluid Dynamics is efficiently used today in turbulent reaction flow simulations to gain a deeper understanding of the combustion process and consequently be able to improve combustor design and reduce emissions.

10. Kinetic Studies of NOx Storage and Reduction Catalysts - Flow Reactor Experiments and Microkinetic Modeling
Abstract : The NOx storage and reduction (NSR) technology is a promising technique to reduce NOx during oxygen excess e.g. in lean burn engine exhaust. A typical NSR catalyst consists of the following components: precious metals, such as platinum, palladium or rhodium, a storage component, usually barium, and a high surface area support, such as γ-alumina.
