Applying qualitative reasoning to finance
Qualitative reasoning has traditionally been applied in the domain of physical systems, where there are well established and understood laws governing the behaviour of each `component' in the system. Such application has shown that it is possible to produce models which can be used for explaining …

Qualitative reasoning about fluids and mechanics
… to understand and interact with the world. Qualitative physics is the attempt to capture and formalize this knowledge. An important aspect of qualitative reasoning is the ability to derive the possible behaviors of a given physical system from the structure of the system, using minimal …

Qualitative Reasoning in an Expert System Framework
… generated plans are justified by applying qualitative reasoning to aircraft performance equations. Equations are represented in a semantic network where nodes represent variables and links represent dependent variable influences.

Goal-directed qualitative reasoning with partial states
… and computational complexities of qualitative reasoning about time-varying behavior. Traditional techniques employ qualitative simulation (QS) to compute envisionments (i.e. state-transition graphs) representing all possible behaviors. Unfortunately, QS exhaustively case-splits on …

Qualitative Reasoning Methodology for the Generation of Process Plant Operating Procedures
… can lead to safer and higher performance plants. Qualitative reasoning techniques hold considerable promise in supporting generations of operating procedures, since they are able to describe possible trajectories of a system based on non-quantitative information and provide explanation about …

By Any Means Necessary: The Quandary the CIA Now Faces In Light of Employing Enhanced Interrogation Methods to Combat the War on Terror
… a case for torture, but instead seeks to provide qualitative reasoning through primary and secondary sources which some seek to support enhanced interrogation. </p><p> It will be important to identify why enhanced interrogation techniques are effective and deemed essential by some. If certain …

An investigation into automation of fire field modelling techniques
… in modelling techniques. The system captures the qualitative reasoning of an experienced modeller in the assessment of room geometries in order to setup important initial parameters of the problem. The prototype system is based on artificial intelligence techniques, specifically expert system …

The role of metaphor in user interface design
… systems and novel application is made of the Qualitative Process Theory (QPT) qualitative reasoning model to reason about the behaviour of on-screen objects, the underlying system functionality, and the relationship between the two. This analysis supports reevaluation of the domains between …

Expert systems in on-line process control and fault diagnosis
… based approaches, namely causal search and qualitative modelling based diagnosis, have been investigated. In the approach of causal search the research results reveal that diagnostic efficiency can be achieved through structural decomposition. A systematic approach for developing diagnostic …

On-line fault diagnosis of industrial processes based on artificial intelligence techniques
… fault detection and diagnosis systems based on qualitative modelling have been implemented. For the first one only single abrupt faults have been considered while the second one can cope with single and multiple simultaneous abrupt faults. In order to overcome the problems associated with the …
