Mach (kernel)
Mach () is a kernel developed at Carnegie Mellon University by Richard Rashid and Avie Tevanian to support operating system research, primarily distributed and parallel computing. Mach is often considered one of the earliest examples of a microkernel. However, not all versions of Mach are microkernels. Mach's derivatives are the basis of the operating system kernel in GNU Hurd and of Apple's XNU kernel used in macOS, iOS, iPadOS, tvOS, and watchOS. The project at Carnegie Mellon ran from 1985 to 1994, ending with Mach 3.0, which is a true microkernel. Mach was developed as a replacement for the kernel in the BSD version of Unix, so no new operating system would have to be designed around it. Mach and its derivatives exist within a number of commercial operating systems. These include all using the XNU operating system kernel which incorporates an earlier non-microkernel Mach as a major component. The Mach virtual memory management system was also adopted in 4.4BSD by the BSD de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machynlleth
Machynlleth () is a market town, community and electoral ward in Powys, Wales and within the historic boundaries of Montgomeryshire. It is in the Dyfi Valley at the intersection of the A487 and the A489 roads. At the 2001 Census it had a population of 2,147, rising to 2,235 in 2011. It is sometimes referred to colloquially as ''Mach''. Machynlleth was the seat of Owain Glyndŵr's Welsh Parliament in 1404,''The Welsh Academy Encyclopaedia of Wales''. John Davies, Nigel Jenkins, Menna Baines and Peredur Lynch (2008) pg527 and as such claims to be the "ancient capital of Wales". However, it has never held any official recognition as a capital. It applied for city status in 2000 and 2002, but was unsuccessful. It is twinned with Belleville, Michigan. Machynlleth hosted the National Eisteddfod in 1937 and 1981. Etymology The etymology of the name Machynlleth derives from "ma-" ield, plainand "Cynllaith". History There is a long history of human activity in the Machynllet ...

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number. The local spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATI Mach
The ATI Mach line was a series of 2D graphics accelerators for personal computers developed by ATI Technologies. It became an extension (and eventual successor) to the ATI Wonder series of cards. The first chip in the series was the ATI Mach8. It was essentially a clone of the IBM 8514/A with a few notable extensions such as Crystal fonts. Being one of the first graphics accelerator chips on the market, the Mach8 did not have an integrated VGA core. In order to use the first Mach8 coprocessor cards, a separate VGA card was required. This increased the cost of ownership as one had to purchase two rather than one expansion card for graphics. A temporary solution was presented with the ATI Graphics Ultra/Vantage cards, which combined an ATI 8514 Ultra and VGA Wonder+ into a single card (though using discrete ICs). The Mach32 chip was the follow-up to the Mach8, which finally featured an integrated VGA core, true colour support and a 64-bit datapath to internal memory. Models Mach ...

GNU Mach
GNU Mach is an implementation of the Mach microkernel. It is the default microkernel in the GNU Hurd. GNU Mach runs on IA-32 machines. GNU Mach is maintained by developers on the GNU project. It is distributed under the terms of the GNU General Public License (GPL). History Early versions of the Hurd were developed on top of CMU's Mach 3.0. In 1994, CMU stopped working on Mach, and the GNU Project switched to the University of Utah's Mach 4. The kernel known as "GNU Mach" was derived from Mach 4 once Utah stopped development. The first ChangeLog entry by Thomas Bushnell (rather than by a Utah researcher) is from 16 December 1996. In 2002, Roland McGrath branched the OSKit-Mach branch from GNU Mach 1.2, intending to replace all the device drivers and some of the hardware support with code from OSKit. After the release of GNU Mach 1.3, this branch was intended to become the GNU Mach 2.0 main line; however, as of 2006, OSKit-Mach is not being developed due to lack of activity in ...

Fly Castelluccio Mach
The Fly Castelluccio Mach is a family of Italian paramotors that was designed and produced by Fly Castelluccio of Ascoli Piceno for powered paragliding. Now out of production, when it was available the aircraft were supplied complete and ready-to-fly.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 67. Pagefast Ltd, Lancaster UK, 2003. ISSN 1368-485X Design and development The Mach was designed to comply with the US FAR 103 Ultralight Vehicles rules as well as European regulations. It features a paraglider-style wing, single-place accommodation and a single Solo 210 engine in pusher configuration powering a two-bladed or four-bladed wooden propeller through a reduction drive. As is the case with all paramotors, take-off and landing is accomplished by foot. Inflight steering is accomplished via handles that actuate the canopy brakes, creating roll and yaw.
