Vector control, also called field-oriented control (FOC), is a variable-frequency drive (VFD) control method in which the stator currents of a three-phase AC or brushless DC electric motor are identified as two orthogonal components that can be visualized with a vector. One component defines the magnetic flux of the motor, the other the torque.
A 2018 study from the University of California, Irvine, maintains that Prop 47 was not a "driver" for recent upticks in crime, based upon comparison of data from 1970 to 2015, in New York, Nevada, Michigan and New Jersey, states that closely matched California's crime trends, but that "what the measure did do was cause less harm and suffering ...
Charge carrier density. Charge carrier density, also known as carrier concentration, denotes the number of charge carriers per volume. In SI units, it is measured in m −3. As with any density, in principle it can depend on position. However, usually carrier concentration is given as a single number, and represents the average carrier density ...

An Electronic Waste Recycling Fee is a fee imposed by government on new purchases of electronic products. The fees are used to pay for the future recycling of these products, as many contain hazardous materials. Locations that have such fees include the European Union, the US State of California and the province of Ontario, Canada.
In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. [1] The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at this point.
