The Experimental results

The aim of this Master of Engineering (MEng) - Aerospace thesis is to study the structural response and failure of aerospace grade composites during exposure to fire. Key aspects of the research are to analyse the thermal and mechanical responses of laminates and sandwich composites in high temperature and fire environments, which result in softening and structural failure. The research is concentrated on carbon/epoxy laminates and sandwich composites, which are the most common composite materials used in aerospace structures.

The focus of this thesis was to study the chemotaxonomic relationship of selected southern Australian marine brown algae of the genera Cystophora and Sargassum. Consequently, this resulted in the isolation and structure elucidation of six new terpenoids from two southern Australian marine brown algae Cystophora moniliformis and Sargassum fallax together with 10 previously reported natural products. As a result of the re-isolation of these known secondary metabolites, updated and complete structural characterisation data could be provided for the first time for 7 of these compounds.

This thesis investigates the SPH capability available in the commercial Finite Element (FE) code LS-DYNA®, for water impact problems. Experiments have been conducted on rigid wedges impacting water, which were then simulated with the SPH method. Although certain limitations were experienced with the experimental results, a positive correlation was observed with the numerical technique, thus establishing SPH as a promising method for crashworthiness design.

The proposed research aims to investigate the influences of temperature on the water retention behaviour of deformable unsaturated soil. Volume change caused by temperature variation will be taken into consideration. This research will produce a better understanding and interpretation of thermal effects on SWCCs by providing experimental results for deformable unsaturated soils.

This paper suggests a solution for the image segmentation (IS) problem with the multilevel thresholding based on one of the latest hybrid swarm computation optimization algorithms, particle swarms, and gravitational search (PSGA). The experimental results are comparable with other state-of-the-art algorithms that show that the PSGA on selected images is better than the competitors.

The thesis is performed theoretically and experimentally. The theoretical studies on the dynamics of the single short pulse emission using transient cavity method and narrow linewidth and tunable wavelength generation using Littrow grating configuration were performed. On the other hand, the experimental investigations were carried out Experimental research was carried out based on the optimal results obtained by the theoretical studies.

The thesis is devoted to constructing and evaluating versions of the SM extended with an A4 symmetry to explain some of the problems of neutrino physics. Within these extended models, the results on neutrino masses and mixing, derived by the perturbation method, are very closed to the global fit. In two models, a relation between the Dirac CPV phase and the mixing angles is established. In particular, the models predict Dirac CPV phase δCP and effective mass of neutrinoless double beta decay jhmeeij in good agreement with the current experimental data.

We have investigated the thermodynamic properties of the cubic zirconia ZrO2 using the statistical moment method in the statistical physics. The free energy, thermal lattice expansion coefficient, specific heats at the constant volume and those at the constant pressure, CV and CP , are derived in closed analytic forms in terms of the power moments of the atomic displacements.
