This thesis deals with the finite element simulation of spot welded joint in crash analysis. Spot welding is a very common joining process in the automotive industry. It is cost effective and it provides a very fast production rate of automotive body components. Despite this advantage, spot welds are very susceptible to various types of loading conditions. Therefore they are prone to failure, if not designed properly, during their service life time. Therefore it is very important to understand the behaviour of spot welds and their failure characteristics.

This study focuses on experimental testing and subsequent numerical analysis of impacted and pre-loaded composite coupons and bonded composite scarf joints under varying impact conditions. A methodology will be developed for the numerical modelling of preloaded impact tests to enable capture of critical failure modes and ultimate failure. The main aim is to validate a modelling strategy that will provide accurate failure characterisation of the tested joints using numerical analysis.

This study explores the way in which Primary School Principals perceive and experience emotions in their day-to-day lives. To understand the varying elements of school leadership a qualitative research approach using semi-structured interviews was used, which was appropriate due to the social and psychological nature of the topic being studied. Two interviews were conducted a year apart with participants to provide a detailed examination of the participants’ experiences and to gain deeper insights into their perceptions of emotions in their work.

The primary goal of this research is accomplishing the BUUAS that can realize functions in the mission profile. In order to achieve this, the project starts with developing elemental aspects of the BUUAS. The configuration and propulsion system are two basic elements that the BUUAS must have to realize successfully operation. Besides, the necessary transition process between water and air must be investigated and carried by a conceived system.

This thesis derives closed form equations to describe electromagnetic device characteristics for a toroid, solenoid and a case study induction machine. By considering stored magnetic field energy, this approach allows the relationship between electrical, magnetic and kinetic energy to be quantified and analyzed in ways that allows improved accuracy compared with conventional magnetic circuit modeling methods. This thesis also provides insights into how geometric parameters impact energy transfer and operational characteristics of electromagnetic devices.

This thesis focuses on the management control function in Australian small businesses. The main function of a Management Control System (MCS) is strategy implementation. It is the system used by management to plan and control the firm’s performance. Elements of the MCS include strategic planning, budgeting, resource allocation, forecasting, performance measurement and evaluation and the core management accounting system (Anthony & Govindarajan, 2007).

This research is qualitative, adopting an exemplar single case study approach with more than one unit of analysis embedded within the case. This research also takes an interpretivist view with the aim of developing concepts, confirming or refuting theory, drawing from specific implications and the contribution of rich insights. A public hospital in Malaysia currently operating with an end-to-end hospital IS/IT was selected as the case to explore the key elements that contribute to the success of assimilating HIS.

A new electromechanical press for fuel pellet manufacturing was built last year in partnership between CEA-Marcoule and ChampalleAlcen. This press was developed to shape pellets in a hot cell via remote handling. It has been qualified to show its robustness and to optimize the compaction cycle, thus obtaining a better sintered pellet profile and limiting damage.
