Prognostics and health management for multi-component systems
… needs. These systems are being fitted with more components which bear stochastic and economic dependencies. Therefore maintaining such systems is becoming more and more of a challenge, especially due to their degradation processes becoming highly stochastic in nature. This thesis is concerned …

Study on Methods of Simultaneous Multi-Component Analysis.
… to assist in the quantitative analysis of multi-component samples in the hope of alleviating the need of tedious separation and cleanup procedures. These newer chemometric procedures tend to be complex and difficult to understand and implement and are successful under different …

Development of multi-component iron-based amorphous alloy
… difficult for recrystallisation to occur. Of the multi-component alloys it was concluded that Fe\(_{60.9}\)Mn\(_{10}\)Mo\(_{10}\)C\(_5\)B\(_{14.1}\) had the best GFA as it had the highest values for each of the parameters used to describe GFA. It is believed that this is due to competition between …

Synthesis of heterocycles via isocyanide-based multi-component reactions
This thesis deals with the development of a new multi-component reaction for the synthesis of heterocycles involving the process of insertion of isocyanides into a carbon-palladium bond. The application to the synthesis of oxazolines was explored and was shown to give good yields of …

Multi-component boron coatings on low carbon steel AISI 1018
… complex properties of B-Me-Fe system. To study multi-component boron coatings on low carbon steel AISI 1018, the simultaneous powder pack method of boronizing and metalizing was selected to perform the coatings. One B-Fe system and eight boron-metal (B-Me-Fe) systems from transition metals group …

Multi-Component Characterization of Strain Rate Sensitivity in Pharmaceutical Materials
… Strain rate sensitivity was assessed using a multi-component approach. The scaled values of three lab-scale parameters: 1) Indentation Creep SRS Exponent, 2) ΔSFfinal, and 3) Heckel-Based SRS Index were used to describe material behavior. Using this combination of parameters, the sensitivity …

Characterising the porosity of multi-component mixtures in rotary mills
Porosity, or fractional void volume, is a simple but powerful quantity used in describing porous media. Characterising this very important parameter is vital to understanding key processes that occur in porous media, such as fluid transport. This is because porosity is strongly related to the …

Animal welfare in South Africa : a multi-component programme design
… Increasingly, research points to the need for a multifaceted approach in dealing with the problem of animal maltreatment due to its complex nature as well as the fact that it is based on a large number of confounding personal, familial, social, cultural and psychological factors. To address this …
