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 main aims of physical geodesy are to study the shape of the Earth, its gravity field and the geoid which is an equipotential surface closest to the mean sea level. Precise geoid determination has been an important research topic in geodesy and geophysics in the past two decades. Scientists and government agencies all around the world have made great efforts on the development of highaccuracy geoid models.

One of the limitations of the BDI (Belief-Desire-Intention) model is the lack of any explicit mechanisms within the architecture to be able to learn. In particular, BDI agents do not possess the ability to adapt based on past experience. This is important in dynamic environments as they can change, causing previously successful methods for achieving goals to become inefficient or ineffective.

This is a qualitative collective case study that seeks to understand the phenomena of graffiti and its related subcultures. By employing Interpretivist techniques, the research attempts to raise questions about harm minimisation, zero tolerance and graffiti, as well as broaden the debate about these distinct policy approaches for local communities. The research setting encompasses the geographic area of the Knox municipality, situated in outer eastern Melbourne.

This thesis examines the capital structure choice of Australian firms with an emphasis on the impact of market timing and liquidity considering 1438 available firms for the period, 1997 to 2005. The relationship between capital structure and its determinants is the main focus of this thesis, with four empirical analyses. These analyses are all conducted within the Baker and Wurgler (2002) and Hovakimian (2006) models with both pooled ordinary least squares (OLS) and fixed effect panel analysis.

Objects, when understood as retrieval cues for memories, may elicit psychological benefits and connections to an individual's past. They are integral to our life story and help to form our individual sense of identity and ability to establish a sound psychological foundation. Transitional objects are an important related category of objects that have been identified in this research. The concept and use of transitional objects and their related phenomena during infancy is well researched, whereas the impact and importance beyond infancy is less established.

This is an empirical investigation into the development of the accounting profession in Sri Lanka in the post-independence era. Taking the Institute of Chartered Accountants of Sri Lanka (ICASL) as a case, the study researches the accounting professionalization process during the past five decades (1959-2010). Thus, the study focuses on the struggles and interactions between competing groups and organisations within the accounting profession.

Application of modem human resource management practices in supporting development of human resource in public sector is the prevailing trend during the past two decades in many developed countries. In particular, the application of competency framework in supporting human resource management practices such as recruitment, planning, training, training, evaluation or compensation is essential.

The human b-globin gene locus is the subject of intense study, and over the past two decades a wealth of information has accumulated on how tissue-specific and stage-specific expression of its genes is achieved. The data are extensive and it would be difficult, if not impossible, to formulate a comprehensive model integrating every aspect of what is currently known. In this review, we introduce the fundamental characteristics of globin locus regulation as well as questions on which much of the current research is predicated.

Protein phosphorylation is a key mechanism for intracellular signal transduction in both prokaryotic and eukaryotic cells. Vertebrate proteins are prevalently phosphorylated on side chains that contain a hydroxyl group, such as serine, threonine and tyrosine residues. In the past decade, however, an increasing number of examples of histidine phosphorylation has been described.

To sustain life mammals have an absolute and continual requirement for oxygen, which is necessary to produce energy for normal cell survival and growth. Hence, main-tainingoxygen homeostasis is a critical requirement and mammals have evolved a wide range of cellular and phy-siological responses to adapt to changes in oxygen avail-ability. In the past few years it has become evident that the transcriptional protein complex hypoxia-inducible factor (HIF) is a key regulator of these processes.

Transport of solutes and polypeptides across membranes is an essential process for every cell. In the past, much focus has been placed on helical transporters. Recently, the b-barrel-shaped transporters have also attracted some attention. The members of this family are found in the outer bacterial membrane and the outer membrane of endosymbiotically derived organ-elles.

U2 snRNP auxiliary factor (U2AF) is an essential heterodimeric splicing factor composed of two subunits, U2AF 65 and U2AF 35 . During the past few years, a number of proteins related to both U2AF 65 and U2AF 35 have been discovered. Here, we review the conserved structural features that characterize the U2AF protein families and their evolutionary emergence.

SR protein kinases (SRPKs) phosphorylate Ser⁄Arg dipeptide-containing proteins that play crucial roles in a broad spectrum of basic cellular processes. Phosphorylation by SRPKs constitutes a major way of regulating such cellu-lar mechanisms. In the past, we have shown that SRPK1a interacts with the nuclear matrix protein scaffold attachment factor B1 (SAFB1) via its unique N-terminal domain, which differentiates it from SRPK1.

Cholesterol oxidase is a bacterial FAD-containing flavooxidase that catalyzes the first reaction in cholesterol catabolism. Indeed, this enzyme catalyzes two reactions: the oxidation of the C3 -OH group of cholesterol (and other sterols) to give cholest-5-en-3-one; and its isomerization to cholest-4-en-3-one. In the past several years, the structural and functional characterization of choles-terol oxidase has been developed together with its application as a biological tool.
