Power systems CAD in system operating conditions. Several electrical engineering calculations and tests can be performed on a power systems CAD model, including: 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
Computer-assisted reporting other disciplines by journalists. One researcher argues the "age of computer-assisted reporting" began in 1952, when CBS television used a UNIVAC I computer to analyze returns from the U.S. presidential election. One of the earliest examples came in 1967, after riots in Detroit, when Philip Meyer of the Detroit Free Press used a mainframe computer to show that people who had attended college were equally likely to have rioted as were high school dropouts. Since the 1950s, computer-assisted developed to the point that databases became central to the journalist's work by the 1980s. In his book, Precision Journalism, the first
