The first-generation Surface (launched as Surface with Windows RT, [2] later marketed as Surface RT) [3] is a hybrid tablet computer developed and manufactured by Microsoft. Announced in June 2012, it was released in October 2012, and was the first personal computer designed in-house by Microsoft.
Generally, forced convection heat sink thermal performance is improved by increasing the thermal conductivity of the heat sink materials, increasing the surface area (usually by adding extended surfaces, such as fins or foam metal) and by increasing the overall area heat transfer coefficient (usually by increase fluid velocity, such as adding ...
A hotfix is a software update that is released outside the normal update cycle or intended to be applied to a live system; often to fix a bug. [1] Originally, hotfix referred to patching a hot system – a production server that is actively serving clients. For development, such a change usually must be designed quickly and outside normal ...
Free-convection flow around a pin-fin heat sink. Generally, the more surface area a heat sink has, the better its performance. [2] Real-world performance depends on the design and application. The concept of a pin fin heat sink is to pack as much surface area into a given volume as possible, while working in any orientation of fluid flow. [2]
Underfloor heating and cooling is a form of central heating and cooling that achieves indoor climate control for thermal comfort using hydronic or electrical heating elements embedded in a floor. Heating is achieved by conduction, radiation and convection. Use of underfloor heating dates back to the Neoglacial and Neolithic periods.
The English writer Hugh Plat proposed a steam-based central heating system for a greenhouse in 1594, although this was an isolated occurrence and was not followed up until the 18th century. Colonel Coke devised a system of pipes that would carry steam around the house from a central boiler, but it was James Watt the Scottish inventor who was ...
Trace heating may be used to protect pipes from freezing, to maintain a constant flow temperature in hot water systems, or to maintain process temperatures for piping that must transport substances that solidify at ambient temperatures. Electric trace heating cables are an alternative to steam trace heating where steam is unavailable or ...
Windows 8 is a major release of the Windows NT operating system developed by Microsoft.It was released to manufacturing on August 1, 2012, made available for download via MSDN and TechNet on August 15, 2012, [6] and generally released for retail on October 26, 2012.
