Method of producing

This thesis describes a quality method that was developed to measure the quality of a tool or technique based on the results it produces. Based on the results of these measurements on current carving tools, a number of areas were identified that could be improved. A new carving framework was developed to address these points of improvements, and its results were tested using the previously developed quality method. The new carving framework achieved significantly better results on all identified improvement areas.

This study focuses on the stability of nano-emulsions produced by phase inversion temperature method using n-Decane and n-Dodecane as the dispersed phase and pure water/brine as the aqueous phase (continuous phase). A non-ionic surfactant (Brij 30) was used in the preparation of the nano-emulsions. Three different types salt namely \(NaCl\), \(KCl\) and \(MgC{l_2}\) were used at different concentrations.

The recent advances in the study of the unique capabilities of monolayer crystals had predicted piezoelectricity in two-dimensional (2D) group IV chalcogenides which are not present in their bulk forms. In this study, the predicted piezoelectric properties of was experimentally explored through Piezoelectric Force Microscopy (PFM). Tin Sulfide (SnS), Tin Selenide (SnSe), Germanium Sulfide (GeS), were exfoliated from their bulk forms by the top down methods of liquid sonication, while and Tin Disulfide (SnS2) mechanically exfoliated by tape.

For this study, different volume fraction (vol.%) of particulate alumina (Al2O3) reinforced aluminium alloy (Al 6061) with 5 vol.%, 15 vol.% and 25 vol.% are produced by powder metallurgy method. These samples were subjected to biaxial stresses in order to investigate the behaviour of the metal matrix composites (MMCs). Microstructure analysis on the individual sample before and after loading was performed under scanning electron microscopy. The small particles of 2 µm in size have exhibited strong interfacial bonding with the matrix.

In this article, we will first discuss the issues of the prompt g-ray spectroscopy regarding the control of all the uncertainties involved in the (n,n0g) cross section estimation. Secondly, we will focus on the role of theoretical modeling which, in certain cases, is crucial to reach the objectives of a few percent uncertainty on the (n,n0) cross sections.

In this paper, the severe plastic deformation method (SPD) known as constrained groove pressing (CGP) was applied to produce ultrafine-grained microstructure in IF steel sheets. In the CGP technique, samples are subjected to repetitive shear deformation under the plane strain deformation condition using the constrained grooved and flat dies.

Pest control practices in the vegetable crops have been heavily dominated by the routine use of broad-spectrum insecticides to control pests. Concerns have emerged about the adverse consequences of over use of pesticide. These consequences include short and longterm health hazards, contamination and environmental degradation. To minimize the pest losses farmers heavily depend on the chemical pesticides and accessing pest management information from the pesticide dealers due to weak state extension support system.

I present the investigation involving two extensions of the cellular automaton based NagelSchreckenberg model, the Velocity-Dependent-Randomisation (VDR) model, and the two-lane model for symmetric and asymmetric lane changing rule sets. The study of the VDR model outlines a potential method in extending the lifetime of a metastable state and consequently postponing an inevitable traffic jam by orders of magnitude. The two lane model produces a so called "critical" and "sub-critical" flow which combined cause the collapse of flow at a critical density.
