Fans attached to components are usually used in combination with a heat sink to increase the area of heated surface in contact with the air, thereby improving the efficiency of cooling. Fan control is not always an automatic process. A computer's BIOS can control the speed of the built-in fan system for the computer. A user can even supplement ...
In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available. Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a ...
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).
" Gretchen am Spinnrade" (Gretchen at the Spinning Wheel), Op. 2, D 118, is a Lied composed by Franz Schubert using the text from Part One, scene 15 of Johann Wolfgang von Goethe's Faust. With "Gretchen am Spinnrade" and some 600 other songs for voice and piano, Schubert contributed transformatively to the genre of Lied .
A Software Process Improvement Network (SPIN) is an organization of professionals who are interested in software and systems process improvement. As of a few years ago, there were 116 SPINs in 37 countries worldwide in their individual geographical areas. [citation needed] Each SPIN is a completely independent organization.
Each electron spin S L or S R define one quantum two-level system, or a spin qubit in the Loss-DiVincenzo proposal. A narrow gate between the two dots can modulate the coupling, allowing swap operations. The Loss–DiVicenzo quantum computer proposal tried to fulfill DiVincenzo's criteria for a scalable quantum computer, [3] namely:
A propfan, also called an open rotor engine, open fan engine [1] [2] or unducted fan (as opposed to a ducted fan), is a type of aircraft engine related in concept to both the turboprop and turbofan, but distinct from both. The design is intended to offer the speed and performance of a turbofan, with the fuel economy of a turboprop.
