  2. Switched-mode power supply - Wikipedia

    en.wikipedia.org/wiki/Switched-mode_power_supply

    The basic schematic of a boost converter. For example, if a DC source, an inductor, a switch, and the corresponding electrical ground are placed in series and the switch is driven by a square wave, the peak-to-peak voltage of the waveform measured across the switch can exceed the input voltage from the DC source. This is because the inductor ...

  3. SCADA - Wikipedia

    en.wikipedia.org/wiki/SCADA

    SCADA (an acronym for supervisory control and data acquisition) is a control system architecture comprising computers, networked data communications and graphical user interfaces for high-level supervision of machines and processes.

  4. Rectifier - Wikipedia

    en.wikipedia.org/wiki/Rectifier

    A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction.

  5. Dagger (mark) - Wikipedia

    en.wikipedia.org/wiki/Dagger_(mark)

    A dagger, obelisk, or obelus † is a typographical mark that usually indicates a footnote if an asterisk has already been used. [1] The symbol is also used to indicate death (of people) or extinction (of species or languages). [2]

  6. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    Schematic of a simple distillation setup. In simple distillation, the vapor is immediately channeled into a condenser. Consequently, the distillate is not pure but rather its composition is identical to the composition of the vapors at the given temperature and pressure. That concentration follows Raoult's law.

    en.wikipedia.org/wiki/Treadwheel_crane

    A 13th century drawing of a treadwheel crane. A treadwheel crane (Latin: magna rota) is a wooden, human powered hoisting and lowering device.It was primarily used during the Roman period and the Middle Ages in the building of castles and cathedrals.

    Mathematics is a field of study that discovers and organizes methods, theories and theorems that are developed and proved for the needs of empirical sciences and mathematics itself.

  9. Finite element method - Wikipedia

    en.wikipedia.org/wiki/Finite_element_method

    The mesh is an integral part of the model and must be controlled carefully to give the best results. Generally, the higher the number of elements in a mesh, the more accurate the solution of the discretized problem. However, there is a value at which the results converge, and further mesh refinement does not increase accuracy. [30]
