The ANU 500 m dish has been in operation since 2010 with a mono-tube steam cavity receiver, the SG4 system for the production of steam used for electricity generation. Dynamic modelling of this system is crucial for achieving robust control and optimised performance. This paper presents ongoing work with the dynamic modelling and simulation of a mono-tube steam cavity receiver for direct steam ...

Parkinson's disease is a common and debilitating condition, caused by aberrant activity in a complex basal ganglia-thalamocortical circuit. Therapeutic advances rely on characterising interactions in this circuit. However, recording electrophysiological responses over the entire circuit is impractical. Dynamic causal modelling offers large-scale models of predictive value based on a limited or ...

Roles are meant to capture dynamic and temporal aspects of realworld objects. The role concept has been used with many semantic meanings: dynamic class, aspect, perspective, interface or mode. This paper identifies common semantics of different role models found in the literature. Moreover, it presents a set of conceptual modelling patterns for the role concept that include both the static and ...

ADAPTAPlan project provides dynamic assistance to support the author in developing instructional design tasks which are included in learning design templates generated in terms of user modelling, planning and machine learning techniques, and making a pervasive use of educational specifications (IMS family) and standards (IEEE-LOM, ISO PNP). In this paper we describe how these standards and spec...

Intelligence of machine tools is not conditioned only by application of modern control systems, sensors and other active components. The application of new methods of modelling, that is intelligent design of machine tools and to purposefully predict its properties, is also very effective. Machine tool development for high speed and highly precise cutting demands employment of advanced simulatio...

Reactive systems are. generally, highly successful for dynamic uncertain domains. Analysing why this should be so indicates the main criterion for success is that information apprehended about a given situation can render it certain enough to reliably inform action. A case is made for informing action by dynamic world modelling for domains where this does not hold. When the issue of attending s...

This paper describes a case study involving the dynamic reconfiguration of an office workflow. We state the requirements on a system implementing the workflow and its reconfiguration, and describe the system’s design in BPMN. We then use an asynchronous π-calculus and Webπ∞ to model the design and to verify whether or not it will meet the requirements. In the process, we evaluate the formalisms...

Learning visual context is a critical step of dynamic scene modelling. This paper addresses the problem of choosing the most suitable probabilistic model selection criterion for learning visual context of a dynamic scene. A Completed Likelihood Akaike’s Information Criterion (CL-AIC) is formulated to estimate the optimal model order (complexity) for a given visual scene. CL-AIC is designed to o...

In geotechnical engineering, rock mechanics and engineering geology, depending on the project design, uniaxial strength and static Youngchr('39')s modulus of rocks are of vital importance. The direct determination of the aforementioned parameters in the laboratory, however, requires intact and high-quality cores and preparation of their specimens have some limitations. Moreover, performing thes...
