Abstract:
The Evolvable Virtual Machine abstract architecture (EVMA) is a computational architecture for dynamic hierarchically organised virtual machines. The concrete EVM instantiation (EVMI) builds on traditional stack-based models of computation and extends them by notions of hierarchy and reflection on the virtual machine level. The EVM Universe is composed of a number of autonomous and asynchronously communicating EVM machines. The main contribution of this work lies in the new model of computation and in the architecture itself: a novel, compact, flexible and expressive representation of distribu

Abstract:
<p> The advent of hypervisors revolutionized the computing industry in terms of <i>malware prevention and detection, secure virtual machine managers, </i> and <i>cloud resilience.</i> However, this has resulted in a disjointed response to handling known threats rather than preventing unknown <i>zero-day</i> threats. This thesis introduces a new paradigm to cloud computing &ndash; <i>utility virtual machines</i> &ndash; that directly leverages virtualization hardware for protection and eliminates often accepted roles of the operating system kernel. This represents a break from prevailing practi

Abstract:
With the emergence of cloud computing, computing resources (i.e., networks, servers, storage, applications, and services) are provisioned as metered on-demand services over networks, and can be rapidly allocated and released with minimal management effort. In the cloud computing paradigm, the virtual machine is one of the most commonly used resource carriers in which business services are encapsulated. Virtual machine placement optimization, i.e., finding optimal placement schemes for virtual machines, and reconfigurations according to the changes of environments, become challenging issues. Th

Virtualization environments have become basic building blocks in consolidated data centers and cloud computing infrastructures. By running multiple virtual machines (VMs) in a shared physical machine, virtualization achieves high utilization of hardware resources and provides strong isolation between virtual machines. This dissertation discusses the implementation and the evaluation of an approach, called kernel service outsourcing, which improves the performance and the reliability of guest systems in the virtualized, multi-kernel environments.

With the advent of modern graphics and computing hardware and cheaper sensor and display technologies, virtual reality is becoming increasingly popular in the fields of gaming, therapy, training and visualization. Earlier attempts at popularizing VR technology were plagued by issues of cost, portability and marketability to the general public. Modern screen technologies make it possible to produce cheap, light head-mounted displays (HMDs) like the Oculus Rift, and modern GPUs make it possible to create and deliver a seamless real-time 3D experience to the user. 3D sensing has found an applicat

Abstract:
This thesis investigates the development of a low cost, component based facial virtual conferencing system. The design is decomposed into an encoding phase and a decoding phase, which communicate with each other via a network connection. The encoding phase is composed of three components: model acquisition (which handles avatar generation), pose estimation and expression analysis. Audio is not considered part of the encoding and decoding process, and as such is not evaluated. The model acquisition component is implemented using a visual hull reconstruction algorithm that is able to reconstruct

This research stems from the premise that Enterprise Systems (ES) are perceived to be challenging to use as these systems impose rigid processes and practices on ES users. Scholars argue that the mismatch between the embedded business processes of ES and the work practices of people in organisations places constraints on how tasks are coordinated and completed in practice. They propose that in order to be responsive, ES not only need to integrate data and processes, but also need to resolve the interdependencies of tasks of different divisions.
