Magnetic bearing systems have received much attention in the research community for the past decades. Its inherent nonlinearity and open-loop instability present challenges for controller design. This thesis investigates and designs model predictive control (MPC) systems for an experimental Active Magnetic Bearing (AMB) laboratory system. A host-target development environment of real-time control system with hardware in the loop (HIL) is used for implementation of the predictive control systems. In this thesis, both continuous and discrete time model predictive controllers are studied.

The problem investigated is the potential gap between the rhetoric of the 'promise of e-business' versus the dynamics of enactment and impacts of ICT in practice in the social enterprise sector. The main contribution of the research is to identify the real development impact of lCT use by social enterprises by assessing the role of ICTs in achieving their goals. Its major finding is that SEs' social and business missions are inextricably linked .and their use of ICTs and benefits from it can be used as a proxy to assess ICTD. Thus SEs provide a new paradigm in the study of ICTD.

The aim of this research is to produce information on decision making in relation to fertiliser use. This information can be used in the Game Theory model to calculate optimal strategies on phosphorus fertiliser application amounts for the individuals within the group. If the results indicate a benefit to the individual and the community as a whole, and are seen as practical, then on a catchment wide basis this should lead to changes in management practices that will minimise phosphorus pollution of the Hopkins River catchment’s waterways.

The aim of the research is to explore the effects of Thai culture on the efficacy of Western modelled performance management (PM) in a cross-cultural setting. Thailand is becoming increasingly important to Australian businesses, particularly in view of the ASEAN Economic Community Plan, which is now in its final stages implementation (ASEAN 2015). The primary data for this study was sourced from 43 semistructured and in-depth interviews with 30 participants.

In recent years, optical orthogonal frequency division multiplexing (OOFDM) has emerged as a dominant research and development area in the field of high-speed optical communications. OFDM is a potential candidate as the most promising next-generation optical networks such as passive optical networks and optical transport networks, due to their simple configuration based on low cost, high speed data rates, high spectral efficiency, high quality of service and robustness against narrow band interference, frequency selective fading, and chromatic dispersion.

The angiogenic process in the central nervous system (CNS) is basically regulated by typical angiogenic signaling systems such as vascular endothe-lial growth factor (VEGF)–VEGF receptors and angiopoietin–Tie recep-tors. In addition to regular endothelial–pericyte interaction, the CNS vasculature has a unique system of cell to cell communication between endothelial cells and astrocytes which is known as the blood–brain barrier.

In Vietnam rodents are one of the three most important problems identified by the agricultural sector. The damage caused by rodents in agricultural systems is an important impediment to rural development in the Mekong Delta region. This proposal capitalises on the research findings and on the measurement of farmers' belief and practises associated with rodent control in the Mekong Delta.

Abstract Intercellular signaling by cytokines is a vital feature of the innate immune system. In skin, an inflammatory response is mediated by cytokines and an entwined network of cellular communication between T-cells and epidermal keratinocytes. Dysregulated cytokine production, orchestrated by activated T-cells homing to the skin, is believed to be the main cause of psoriasis, a common inflammatory skin disorder.
