This paper combines the Activity Theory approach with the Semiotics approach as a knowledge elicitation technique. As being understood increasingly, not only is it difficult and time-consuming to build KBSs, the introduction of a knowledge engineer between the domain expert and the knowledge base could lead to errors and misunderstandings. We view knowledge(More)
Knowledge becomes a pivotal factor for intelligence to support decision making. Elicitation, representation and use of knowledge are major areas of research in the field of Artificial Intelligence, leading to development of knowledge bases and expert systems. Knowledge base system (KBS) development is complex, expensive, and time consuming process that(More)
An artificial neural network (ANN) has been designed to simulate and predict the torque and force acting on the outer stationary sphere due to steady state motion of the second order fluid between two eccentric spheres by a rotating inner sphere with an angular velocity Ω The (ANN) model has been trained based on the experimental data to produce the torque(More)
