—The use of the web for a variety of educational needs has exploded recently. It provides one approach in the increasing use of electronic media. HTML—the " Lin-gua Franca " of the internet—provides great platform independence. However, for mathematically intensive applications as seen in Engineering, HTTP and HTML are not able to compete with non-web(More)
Translating from a problem description given in a natural language to a solution expressed in a programming language requires many complex steps. Though many of these steps can be done mentally for simple problems, the process itself is important when dealing with complicated software. Expressing the process demonstrates not only the complexity of solving a(More)
In this paper, we investigate a novel online estimation algorithm for dynamic Bayesian network (DBN) parameters, given as conditional probabilities. We sequentially update the parameter adjustment rule based on observation data. We apply our algorithm to two well known representations of DBNs: to a first-order Markov chain (MC) model and to a hidden Markov(More)
There is a need for more effective science teaching strategies for science teachers with large numbers of English-as-a-second-language (ESL) students in grades seven and eight. The nature of science lends itself well to concrete activities that offer students the opportunity to, not only learn English vocabulary, but to gain a better grasp of concepts when(More)
This paper describes a Direct Torque Controlled (DTC) Induction Machine (IM) drive that employs feedback linearization and sliding-mode control. A feedback linearization approach is investigated, which yields a decoupled linear IM model with two state variables: torque and stator flux magnitude. This intuitive linear model is used to implement a DTC type(More)
