The KATE shell: An implementation of model-based control, monitor and diagnosis
The conventional control and monitor software currently used by the Space Center for Space Shuttle processing has many limitations such as high maintenance costs, limited diagnostic capabilities and simulation support. These limitations have caused the development of a knowledge based (or model based) shell to generically control and monitor electro-mechanical systems. The knowledge base describes the system's structure and function and is used by a software shell to do real time constraints checking, low level control of components, diagnosis of detected faults, sensor validation, automatic generation of schematic diagrams and automatic recovery from failures. This approach is more versatile and more powerful than the conventional hard coded approach and offers many advantages over it, although, for systems which require high speed reaction times or aren't well understood, knowledge based control and monitor systems may not be appropriate

Curiosity into creation: Can we teach science through engineering?
An examination of how the science objectives of the primary national Curriculum can be taught through the engineering design process and through 'real-world' contextualized engineering problems
Robustness and fault tolerance make brains harder to study
Brains increase the survival value of organisms by being robust and fault tolerant. That is, brain circuits continue to operate as the organism needs, even when the circuit properties are significantly perturbed. Kispersky and colleagues, in a recent paper in Neural Systems & Circuits, have found that Granger Causality analysis, an important method used to infer circuit connections from the behavior of neurons within the circuit, is defeated by the mechanisms that give rise to this robustness and fault tolerance
Web-based eTutor for learning electrical circuit analysis
This paper discusses a web-based eTutor for learning electrical circuit
analysis. The eTutor system components, mainly the user-interface and the assessment
model, are described. The system architecture developed provides a framework to
support interactive sessions between the human and the machine for the case when the
human is a student and the machine a tutor and also for the case when the roles of the
human and the machine are swapped. To motivate the usefulness of the data gathered,
some examples of interactive sessions are given and models to capture both declarative
and procedural knowledge during learning are discussed. A probabilistic assessment
model is reviewed and future directions in the field of eTutors for electrical circuits are
discussed.peer-reviewe
