Faculty of Engineering and Information Sciences - Papers: Part A
We describe the process of designing a reliable and valid instrument for collecting network and attribute data. Here, we explore the relationship between social networks structure, information and communication technologies (ICT) use and attitude towards performance in knowledge intensive work. We first develop a model for exploring the inherent relationship between the three concepts based on existing literature. We then develop appropriate item sets for measuring different independent (network structure, ICT use) and dependent variables (performance). We use the reliable item sets along with justifications to construct different phases of our instrument. In doing so, we introduce a simulation approach …

Conducting polymers, such as polythiophenes, are promising low voltage actuator materials. The performance of these materials has improved significantly in recent years. A remaining problem, however, is the significant decline in the actuation strain produced when the external stress is increased. Using a poly(3-methylthiophene) actuator in an ionic liquid electrolyte it is shown that the isotonic actuation actually increases with increasing applied stress. The work output per cycle consequently increases at higher stresses, which is very desirable for practical devices. Although theoretically predicted, these results are the first demonstration of the increased actuator performance at higher operating stresses. The actuation …

Linear elastic fracture mechanics was used to optimise the vacuum-heat-treatment procedures for conventional hot-work AISIHII tool steel. The fracture toughness was determined with non-standard, circumferetially notched and fatigue-precracked tensile-test specimens.
