Warnier/Orr diagrams show the processes and sequences in which they are performed. Each process is defined in a hierarchical manner i.e. it consists of sets of subprocesses, that define it.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
Leonid Kantorovich John von Neumann. The problem of solving a system of linear inequalities dates back at least as far as Fourier, who in 1827 published a method for solving them, [4] and after whom the method of Fourier–Motzkin elimination is named.
Free-body diagram of a U-channel synchronous linear motor. The view is perpendicular to the channel axis. The two coils at centre are mechanically connected, and are energized in "quadrature" (meaning a phase difference of 90° (π/2 radians) between the flux of the magnets and the flux of the coils).
The ‘Ciudad Lineal’ takes a form of a city 400 meters wide, centered on a tramway (line 70 - closed in 1972) and a thoroughfare running in parallel. The main street in the district, calle de Arturo Soria, bears his name. The city is the current headquarters for the flag carrier airline of Spain, Iberia. [1]
