They were initially developed 1976, [1] in France by Jean-Dominique Warnier [2] and in the United States by Kenneth Orr [3] on the foundation of Boolean algebra. [4] This method aids the design of program structures by identifying the output and processing results and then working backwards to determine the steps and combinations of input ...
IEC 61131-3 is the third part (of 10) of the international standard IEC 61131 for programmable logic controllers. It was first published in December 1993 [1] by the IEC; the current (third) edition was published in February 2013. [2] Part 3 of IEC 61131 deals with basic software architecture and programming languages of the control program ...
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.
The Sequence diagram of UML Overview. In software engineering, a sequence diagram [1] shows process interactions arranged in time sequence. This diagram depicts the processes and objects involved and the sequence of messages exchanged as needed to carry out the functionality.
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).
A station number written on a silt fence at a construction site. Linear referencing, also called linear reference system or linear referencing system (LRS), is a method of spatial referencing over linear or curvilinear elements, such as roads or rivers.
The planning of Ciudad Lineal (1895-1910) published by Madrid Urbanization Company. Cross-section of a linear city, with wide highways with separate sections for vehicles, pedestrians and trams . The linear city is an urban plan for an elongated urban formation that was proposed by Arturo Soria y Mata in 1882. [ 1 ]
