Switching power supply
| Meteorological Glossary |
A power supply which achieves its output regulation by means of one or more active power handling devices which are alternately placed in the "off" or "on" states. it is more efficient than linear supplies which vary the conduction of

Regulation, английский
- A rule or order prescribed for management or government
- Регулирование
- Регулирование, правило, постановление
- Any rule prescribing permitted or forbidden conduct, whether established by legislation or the action of an administrative agency; also
- The act of regulating the regulation of the body’s temperature
- Any systematic (rule-like or determinate) behavior of one part of a system that tends to restrict the fluctuations in behavior of another part of that system. while both parts must lie in the same feedback loop, regulation involves this basic asymmetry
- The process whereby the designated government authority provides oversight and establishes rules for firms in an industry. regulation places constraints on behavior, establishes good (or bad) incentives, and addresses issues that are politically contentious. decisions are implemented through a rule or order issued by an executive authority or regulatory agency of a government and having the force of law.
- Норма
- A rule or order issued by governmental executive authorities or regulatory agencies and having the force of law. regulations implement policies and are mostly specifi c for particular groups of people, legal entities or targeted activities. regulation is also the act of designing and imposing rules or orders. informational, transactional, administrative and political constraints in practice limit the regulator’s capability for implementing preferred policies.
- The order in which trains are run in practice so as to minimise delay
Conduction, английский
- Conduction
- The direct transfer of heat energy through a material.
- The transfer of energy through a solid without motion of the conducting solid as a whole. steady-state conduction calls if the temperature at each point is independent of time. unsteady or transient conduction situations changes with time (time dependant)
- The process of passing heat, sound or nervous impulses from one part of the body to another
- Проводимость; электрическая проводимость; электропроводность
- The transfer of heat energy through matter.
- The transfer of heat energy in materials (usually solids) via molecular scale vibrations and collision interactions.
- Heat transfer to another body or within a body by direct contact.
- Heat transfer occurring when more energetic particles collide with — and thus impart some of their heat energy to — adjacent less energetic (slower moving) particles. this action is passed on from one atom (or free electron) to the next in the direction of cooler regions. thus, heat always flows from a warmer to a cooler region.1 conductivity, thermal (k): material property defining the relative capability to carry heat by conduction in a static temperature gradient. conductivity varies slightly with temperature in solids and liquids and with temperature and pressure in gases. it is high for metals (copper has a k of 380 w·m–1·k–1) and low for gases and porous materials (concrete has a k of 1.0 w·m–1·k–1).3 682 infrared and thermal testing

Synchro, английский
- A motor like device containing a rotor and a stator and capable of converting an angular position into an electrical signal, or an electrical signal into an angular position. when several synchros are correctly connected, all of the rotors will align them
- An electromagnetic device for transmitting mechanical motion to a remote location. a transmitter emits an electrical signal corresponding to the angle of rotation of its shaft, and a receiver causes its own shaft to rotate to an angle corresponding to the signal. used for the control of propulsion machinery and in fire-control. also called selsyn.
Splayed tail, английский
A type of wind vane having a split or v-shaped tail. the apex orients itself into the direction of the wind.
