2. Nosé–Hoover thermostat - Wikipedia

   en.wikipedia.org/wiki/Nosé–Hoover_thermostat

   Popular techniques to control temperature include velocity rescaling, the Andersen thermostat, the Nosé–Hoover thermostat, Nosé–Hoover chains, the Berendsen thermostat and Langevin dynamics. The central idea is to simulate in such a way that we obtain a canonical ensemble, where we fix the particle number N {\displaystyle N} , the volume ...

3. Fan heater - Wikipedia

   en.wikipedia.org/wiki/Fan_heater

   Portable fan heater A Japanese kerosene fan heater that burns kerosene for fuel. It contains an electric fan and computer controls. Electric fan heater. A fan heater, also called a blow heater, is a heater that works by using a fan to pass air over a heat source (e.g. a heating element). [1]

4. Centrifugal fan - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_fan

   A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).

5. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   In 1882, Philip Diehl developed the world's first electric ceiling mounted fan. During this intense period of innovation, fans powered by alcohol, oil, or kerosene were common around the turn of the 20th century. In 1909, KDK of Japan pioneered the invention of mass-produced electric fans for home use. In the 1920s, industrial advances allowed ...

6. Axial fan design - Wikipedia

   en.wikipedia.org/wiki/Axial_fan_design

   An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the ...

7. Aspirator (medicine) - Wikipedia

   en.wikipedia.org/wiki/Aspirator_(medicine)

   Potain's aspirator. A medical aspirator is a suction machine used to remove mucus, blood, and other bodily fluids from a patient.They can be used during surgical procedures but an operating theater is generally equipped with a central system of vacuum tubes. [1]

8. Andersen thermostat - Wikipedia

   en.wikipedia.org/wiki/Andersen_thermostat

   The Andersen thermostat is a proposal in molecular dynamics simulation for maintaining constant temperature conditions. [1] [2] It is based on periodic reassignment of the velocities of atoms or molecules. For each atom or molecule, the reassigned velocity is picked randomly according to Maxwell–Boltzmann statistics for the given temperature.

9. Nasopharyngeal airway - Wikipedia

   en.wikipedia.org/wiki/Nasopharyngeal_airway

   In medicine, a nasopharyngeal airway (NPA), nasal trumpet (because of its flared end), or nose hose, is a type of airway adjunct, a tube that is designed to be inserted through the nasal passage down into the posterior pharynx to secure an open airway. It was introduced by Hans Karl Wendl in 1958. [1]
