In this thesis, a joint experimental and theoretical investigation of the vector properties that describe the inelastic scattering of a diatomic radical with an atomic collision partner is presented. A particular emphasis is placed on those correlations that include the final rotational angular momentum, j', of the radical. The depolarisation of both NO(A) and OH(A) brought about through collisions with krypton has been studied, providing a measure of the j-j' correlation, where j is the initial rotational angular momentum associated with the diatom.

Abstract:
Investigation of momentum and heat transfer between the fluid and solid phase is critical to the study of fluid-particle systems. Dense suspensions are characterized by the solid fraction (ratio of solid volume to total volume), the particle Reynolds number, and the shape of the particle. The behavior of non-spherical particles deviates considerably from spherical particle shapes which have been studied extensively in the literature. Momentum transfer, to first-order, is driven by drag forces experienced by the particles in suspension, followed by lift and lateral forces, and also through the

Then studying the system in different dynamical regimes we analyse the properties of factorial moments, cumulants and multifractal properties.

Por um lado, a estratégia oferece elevados retornos ajustados ao risco que superam os proporcionados pelas estratégias assentes nos fatores de mercado, value ou size. Mas, por outro lado, este notável desempenho é condicionado por uma elevada exposição ao risco de ‘crash’. i.e., risco de perdas muito elevadas apesar de pouco frequentes.

Then we discused the difference among the flow fields with the different densities, the different velocities (but the same velocity ratio), the different velocity ratios.Finally, we compared with this kind

Abstract:
The momentum anomaly has been widely documented in the literature. However, there are still many issues where there is no consensus and puzzles left unexplained. One is that strategies based on momentum present a level of risk that is inconsistent with the diversification that it offers. Moreover, recent studies indicate that this risk is variable over time and mostly strategy-specific. This work project hypothesises and proves that this evidence is explained by the portfolio constitution of the momentum strategy over time, namely the covariance and correlation between companies in the top and

Abstract:
For over a decade studies of the strong interaction in extremely dense nuclear environments have been done at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. It is hypothesized that colliding two beams of Au nuclei at relativistic speeds creates an environment of hot dense nuclear matter where the quarks and gluons inside the nucleus, which are normally confined within the protons and neutrons, become deconfined into a soup called the quark-gluon plasma. Since direct observation of this short-lived phase is impossible, many sophisticated analysis techniques attemp

According to the recent experimental results from all four experiments at the Relativistic Heavy Ion Collider (RHIC) at the top RHIC energy, sqrtsNN = 200 GeV, it has been widely accepted that a very hot, dense, and possibly new state of matter have produced in central Au+Au collisions at RHIC. The space-time evolution of such collisions is great interest. The technique of Hanbury-Brown and Twiss (HBT)

The rate of return of the momentum investment method found that the multiple correlation coefficient has no obvious correlation with the momentum investment method. In addition, under

Investigation of transport of matter in highly confining media is a very active field of research with numerous applications to bio- and nano-technology. We proceed from a model, called Slicer Map (SM), developed by Salari et al. CHAOS 25, 073113 (2015), that captures some features of anomalous transport, while being analytically tractable. The SM is a one-parameter family of non-chaotic, one-dimensional dynamical systems. Different trajectories

The evidence shows that the short-run effect of merge momentum is uncertain. However, following merging activities, bidder’s return reverse in the long run if merge announcements are intensive, but the more the positive return the bidder has in the short run, the more improvements shareholder’s wealth will have in the long run.

Abstract:
An experimental study on the application of Digital Image Correlation (DIC) to measure the deformation and strain of rotating blades is described. Commercial DIC software was used to obtain measurements on three different types of rotors with diameter ranging from 18 to 39 and with varying flexibility to explore applicability of the technique over a breadth of scales. The image acquisition was synchronized with the frequency of rotation such that images could be obtained at the same phase and the consistency of measurements was observed.
