Beim Entwurf großer Netzwerke der Automation ermöglichen Methoden der Leistungsbewertung den Test und die Dimensionierung eines Netzwerkes bereits vor der Inbetriebnahme und erlauben damit einen effizienten, qualitätsorientierten Entwurf. Es ist jedoch sehr wissensintensiv und aufwendig, entsprechende Analyse- oder Simulations-Modelle aufzustellen und die Ergebnisse auszuwerten, weshalb die Methoden in der Praxis der Automation selten verwendet werden. Viel vertrauter sind dem Entwerfer hingegen die speziellen Software-Tools, mit denen in der Automation Netzwerke entworfen werden. Auf Basis de

Abstract:
Advances in processor design have delivered performance improvements for decades. As physical limits are reached, however, refinements to the same basic technologies are beginning to yield diminishing returns. Unsustainable increases in energy consumption are forcing hardware manufacturers to prioritise energy efficiency in their designs. Research suggests that software modifications will be needed to exploit the resulting improvements in current and future hardware. New tools are required to capitalise on this new class of optimisation. This thesis investigates the field of energy-aware perfo

Abstract:
The facile synthesis of engineering thermoplastics enabled the development of structure-morphology-property relationships for a wide range of applications. Utilizing step-growth polymerization techniques, a myriad of reaction conditions probed various polymer families including polysulfones, polyesters, polyimides and polyureas. Copolymers ranging from random to segmented sequences provided insight into the influence of segment length on physical properties. Melting temperatures, glass transition temperatures, and mechanical properties responded systematically to segment length and morphology.

Abstract:
SYNOPSIS This thesis is concerned with the general and fundamental engineering characterisation of a geological formation within Wianamatta group, known as Bringelly shale. Bringelly shale is the neighbouring member of Ashfield shale; both are soft rocks of Triassic age within a geological structure known as the Sydney basin in the state of New South Wales, Australia. Bringelly shale rock and its residual material cover an approximate area of 700km2. It is found inland, to the west of the city of Sydney, where most of the new residential, commercial and industrial development is taking place.

Abstract:
The structural engineering community is currently exploring the concept of performance-based earthquake engineering (PBEE). In an effort to amend the code-oriented practice, in which life safety is the primary concern, predictions are made regarding the cost and downtime associated with damage. A typical result is the “loss curve,” which represents the annual probability of exceeding various cost thresholds. Such predictions are useful to improve decision making related to structural design by enabling stakeholders to consider the cost of possible future damage, in addition to the construction
