Power systems CAD Power systems CAD In electrical power engineering, power systems CAD is computer-aided design (CAD) software that is used to design and simulate electrical power systems in commercial and industrial buildings. Electrical power systems CAD tools are used by electrical power systems engineers. In the United States alone, power systems are a $100 billion industry. Power systems CAD tools increase the productivity, efficiency, and effectiveness of electrical systems designers by providing a design foundation that allows power systems to be created quickly and by enabling design engineers to test the safety and integrity of their design concepts.

Computer-assisted language learning (e.g. repeating, paraphrasing, slowing down, correcting, or directing the student to background explanations)." Jones C. (1986), on the other hand, rejected the idea of the computer being "some kind of inferior teacher-substitute" and proposed a methodology that focused more on what teachers could do with computer programs rather than what computer programs could do on their own: "in other words, treating the computer as they would any other classroom aid". Warschauer's high expectations in 1996 have still not been fulfilled, and currently there is an increasing tendency for teachers to go down the route proposed by Jones, making use of
