F-segment
The F-segment is the 6th category and largest of the Euro Car Segment, European segments for passenger cars, and always belongs to "Luxury_vehicle#Luxury_saloon_/_full-size_luxury_sedan, luxury cars". The equivalent categories are full-size luxury sedan (or "large luxury sedan") in the United States, luxury saloon (or "luxury limousine") in the United Kingdom, and Oberklasse in Germany. Extended-wheelbase limousines and Armored car (VIP), armored sedans are also considered as F-segment. F-segment is a niche of the European market (approximately 0.2–0.3% in the 2010s) and the range is limited to only a few models. Characteristics Most F-segment cars use a sedan (car), sedan body style, however some have been produced as station wagons, wagons/estates or have a hatchback rear door. Extended wheelbase variants of these cars are common, as many of the luxury features are placed for the rear-seat occupants. In some markets (depending on the manufacturer), short wheelbase models ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Class F Fly Ash
Coal combustion products (CCPs), also called coal combustion wastes (CCWs) or coal combustion residuals (CCRs), are categorized in four groups, each based on physical and chemical forms derived from coal combustion methods and emission controls: *Fly ash is captured after coal combustion by filters ( bag houses), electrostatic precipitators and other air pollution control devices. It comprises 60 percent of all coal combustion waste (labeled here as coal combustion products).It is most commonly used as a high-performance substitute for Portland cement or as clinker for Portland cement production. Cements blended with fly ash are becoming more common. Building material applications range from grouts and masonry products to cellular concrete and roofing tiles. Many asphaltic concrete pavements contain fly ash. Geotechnical applications include soil stabilization, road base, structural fill, embankments and mine reclamation. Fly ash also serves as filler in wood and plastic products, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Class F Fire
A fire class is a system of categorizing fire with regard to the type of material and fuel for combustion. Class letters are often assigned to the different types of fire, but these differ between territories. There are separate standards for the United States, Europe, and Australia. This is used to determine the type of extinguishing agent that can be used for that fire class. Class A: Ordinary combustibles Class A fires consist of ordinary combustibles such as wood, paper, fabric, and most kinds of trash. They may be extinguished by water, wet chemical suppression, or dry chemical powder. Class B: Flammable liquid Class B fires are those where the fuel is flammable or combustible liquid. The US system includes flammable gases in their "Class B". In the European/Australian system, flammable liquids are designated "Class B" having flash point less than . These fires follow the same basic fire tetrahedron (heat, fuel, oxygen, chemical reaction) as ordinary combustibl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Class F Cable
International standard ISO/IEC 11801 ''Information technology — Generic cabling for customer premises'' specifies general-purpose telecommunication cabling systems (structured cabling) that are suitable for a wide range of applications (analog and ISDN telephony, various data communication standards, building control systems, factory automation). It is published by ISO/IEC JTC 1/ SC 25/WG 3 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It covers both balanced copper cabling and optical fibre cabling. The standard was designed for use within commercial premises that may consist of either a single building or of multiple buildings on a campus. It was optimized for premises that span up to 3 km, up to 1 km2 office space, with between 50 and 50,000 persons, but can also be applied for installations outside this range. A major revision was released in November 2017, unifying requirements for commercial, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
F-class Sydney Tram
The F-class trams were a class of two-bogie California combination car trams operated on the Sydney tram network with longitudinal seating in the open part of the car. They were later rebuilt as the L-class trams and some again as the L/P-class trams. History In 1899, F122 was built by Clyde Engineering as a prototype. Deemed a success, a further 250 were built by Clyde Engineering between 1900 and 1902. They were introduced for the electrification of the Eastern Suburbs, South-Western and Western lines. Between 1906 and 1914, all were converted to L class trams at Randwick Tramway Workshops Randwick Bus Depot is a bus depot in the Sydney suburb of Randwick operated by Transdev John Holland. History In 1881 the Randwick Tramway Workshops were established on the corner of Darley Road and King Street, Randwick as the main workshops ... with the open seating altered to a cross-bench configuration, like the K and O class trams, rather than the original cable-tram style outw ...

F-class Melbourne Tram
The F-class was a class of two trams built by Duncan & Fraser, Adelaide, for the Prahran & Malvern Tramways Trust (PMTT). Both passed to the Melbourne & Metropolitan Tramways Board The Melbourne & Metropolitan Tramways Board (MMTB) was a government-owned authority that was responsible for the tram network in Melbourne, Australia between 1919 and 1983, when it was merged into the Metropolitan Transit Authority. It had b ... on 2 February 1920 when it took over the PMTT, becoming the F-class and retaining their running numbers. They were designed as summer cars, with five doors on each side. When rebuilt in 1923, some of the doors were filled in and longitudinal seating was fitted.

Stellar Classification
In astronomy, stellar classification is the classification of stars based on their stellar spectrum, spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a Prism (optics), prism or diffraction grating into a spectrum exhibiting the Continuum (spectrum), rainbow of colors interspersed with spectral lines. Each line indicates a particular chemical element or molecule, with the line strength indicating the abundance of that element. The strengths of the different spectral lines vary mainly due to the temperature of the photosphere, although in some cases there are true abundance differences. The ''spectral class'' of a star is a short code primarily summarizing the ionization state, giving an objective measure of the photosphere's temperature. Most stars are currently classified under the Morgan–Keenan (MK) system using the letters ''O'', ''B'', ''A'', ''F'', ''G'', ''K'', and ''M'', a sequence from the hottest (''O'' type) to the coo ...

F-class Escort Ship
The F-class escort ships were a class of fleet escorts () used by the German Navy ('' Kriegsmarine'') during the Second World War. Ten ships were built in total to fulfil a multi-purpose role. They were the only ships of this type of built by the ''Kriegsmarine''. The ships were not given names, but were designated ''F1'' through ''F10''. Construction The ships were built by Germaniawerft (F 1 – F 6), Kiel, Blohm & Voss (F 7, F 8) and Wilhelmshaven dockyard (F 9, F 10). They entered service between 1936 and 1939. Similar in size to the Type 35 and Type 37 torpedo-boats, the ships were originally conceived as fast fleet or convoy escort ships that could also perform anti-submarine and minesweeping work. They were also used as a testbed class for a new high-pressure steam power plant intended for use in future destroyers. As a class, they were overloaded and over-engined, which contributed to severe hull stress and very poor sea-keeping characte ...

F-Class (shooting Sport)
The International Confederation of Fullbore Rifle Associations (ICFRA) is the international association for the fullbore rifle shooting sports of Target Rifle ('TR') (in the US 'Palma' Rifle) and F-Class, which are long range competitions shot at distances between 300 and 900 meters or 300 to 1,000 yards depending on the range. F-Class shooters often shoot concurrently with the world's long-range TR shooters and use the same targets, except that the F-Class target has an extra ring half the diameter of the smallest in use for TR. ICFRA manages the programme of World Championships and other major matches for Fullbore Rifle and seeks to standardize the competition rules for TR and F-Class around the world. In competitions, wind reading skills are important. In order to hit their targets competitors must sense wind direction and speed and adjust their sights accordingly by applying knowledge and experience about wind's effect on the Trajectory of the bullet.
