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 of corpora and concordancers, interactive whiteboards, Computer-mediated communication (CMC), language learning in virtual worlds, and mobile-assisted language learning (MALL). The term CALI (computer-assisted language instruction) was in use before CALL, reflecting its origins as a subset of the general term CAI (computer-assisted instruction). CALI fell out of favour among language teachers, however, as it appeared to imply a teacher-centred approach (instructional), whereas language teachers are more inclined to prefer a student-centred approach, focusing on learning rather than instruction. CALL began to replace CALI in the early 1980s (Davies & Higgins 1982: p. 3) and it is now incorporated into the
