The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association . [ 1 ]
This produced the Antenna Modeling Program, or AMP, which was extensively modified to support disk-based files, simplify the input and output to make it easier to use, and extensively documented. A follow-up, AMP2, added calculations for extended surfaces like reflectors. [2] NEC is an advanced version of AMP2, with more options and features.
Simulation of negative refraction from a metasurface at 15 GHz for different angles of incidence. The simulations are performed through the method of moments. The method of moments (MoM), also known as the moment method and method of weighted residuals, [1] is a numerical method in computational electromagnetics.

In response to industry demand, CSA has developed Part IV of the Canadian Electrical Code, consisting of two standards CSA C22.4 No. 1 "Objective-based industrial electrical code" and CSA C22.4 No. 2 "Objective-based industrial electrical code - Safety management system requirements".
In the power systems analysis field of electrical engineering, a per-unit system is the expression of system quantities as fractions of a defined base unit quantity. . Calculations are simplified because quantities expressed as per-unit do not change when they are referred from one side of a transformer to t
In rural Georgia, a 10-year-old boy left home and walked a mile down the road to another town, where a concerned citizen called law enforcement. Deputies then arrested the boy’s mother, igniting ...
