Consolidation of applications in cloud computing environments presents a significant opportunity for energy optimization. As a first step toward enabling energy efficient consolidation, we study the inter-relationships between energy consumption, resource utilization, and performance of consolidated workloads. The study reveals the energy performance trade-offs for consolidation and shows that optimal operating points exist. We model the consolidation problem as a modified bin packing problem and illustrate it with an example.

The modelling of traffic flow using methods and models from physics has a long history. In recent years especially cellular automata models have allowed for large-scale simulations of large traffic networks faster than real time. On the other hand, these systems are interesting for physicists since they allow to observe genuine nonequilibrium effects. Here the current status of cellular automata models for traffic flow is reviewed with special emphasis on nonequilibrium effects (e.g. phase transitions) induced by on- and off-ramps.

In this thesis, a numerical model with detailed reaction mechanism which is tailored for studying the behaviour of combustion of natural gas has been introduced and validated with available experimental data. The numerical model attempts to comprehensively simulate the physical conditions (temperature and pressure), equivalent ratio, and fuel dilution and strain rate effect in the laminar flames.

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.

This work investigates the generation of neutron flux inside lead shielding due to cosmic rays as a function of shielding thickness by use of the GEANT Monte-Carlo modelling code. GEANT allows for the Monte-Carlo modelling of the transport of particles in matter. This includes muons, the particles of interest here, which originate from cosmic ray showers.

Tensegrity is a structural system constructed of tensile cables and compressive bars. This thesis proposes several general methods for creating tensegrity structures. The author has developed new methods for creating specific tensegrity cells and the corresponding computer code. Furthermore, the author has constructed various physical models to validate the methods. A proposal for an observation tower on top of the Eureka building in Melbourne has also been devised by the author.

In the last 10 years interest and activity in urban sonic design has expanded. The way we listen to, think about and understand sound determines the way we value, manage and design with it. However practitioners in the area would benefit from detailed forms of site documentation and analysis that go beyond physical sound measurement. This Masters explores the use of the Sonic Identity Model developed by Pascal Amphoux of CRESSON (the Centre for Research on Sonic Space and Urban Environment) in the early stages of urban sonic design.

The primary aim of this research was to further develop the sensing and estimation module of the CHMS framework with an improved multimodal inference model of MWL as needed for the application in aerospace CPHS. Here the focus of this research was on the implementation of a multimodal inference model of MWL that would be developed and experimentally tested. This was done with the purpose of studying the viability of real‐time system adaptation in aerospace systems.

This study uncovers a wide range of complex transport dynamics in transiently forced aquifers that has profound implications for the understanding and quantification of solute transport in these important groundwater systems. And the results in this thesis predict that complex transport structures and dynamics arise in natural transiently forced aquifers around the world. When such dynamics do arise, it will lead to mixing and reactive transport patterns that are very different from those predicted by conventional Darcy flow models.
