Flexible-fuel Vehicle
A flexible-fuel vehicle (FFV) or dual-fuel vehicle (colloquially called a flex-fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank. Modern flex-fuel engines are capable of burning any proportion of the resulting blend in the combustion chamber as fuel injection and spark timing are adjusted automatically according to the actual blend detected by a fuel composition sensor. Flex-fuel vehicles are distinguished from bi-fuel vehicles, where two fuels are stored in separate tanks and the engine runs on one fuel at a time, for example, compressed natural gas (CNG), liquefied petroleum gas (LPG), or hydrogen. The most common commercially available FFV in the world market is the ethanol flexible-fuel vehicle, with about 60 million automobiles, motorcycles and light duty trucks manufactured and sold wo ...

Flex Circuit
Flexible electronics, also known as ''flex circuits'', is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester film. Additionally, flex circuits can be screen printed silver circuits on polyester. Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use. Manufacturing Flexible printed circuits (FPC) are made with a photolithographic technology. An alternative way of making flexible foil circuits or flexible flat cables (FFCs) is laminating very thin (0.07 mm) copper strips in between two layers of PET. These PET layers, typically 0.05 mm thick, are coated with an adhesive which is thermosetting, and will be activated during the lamination process. FPCs and FFCs have several advantages in many applications: * Tigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CSS Flexible Box Layout
CSS Flexible Box Layout, commonly known as Flexbox, is a CSS 3 web layout model. It is in the W3C's candidate recommendation (CR) stage. The flex layout allows responsive elements within a container to be automatically arranged depending on viewport (device screen) size. Concepts Most web pages are written in a combination of HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets). In short, HTML specifies the ''content and logical structure of the page'', while the CSS specifies ''how it looks'': its colors, fonts, formatting, layout, and styling. CSS flex-box layout is a particular way to specify the layout of HTML pages. One of the most defining features of the flex layout is its ability to form-fit, based on its viewing environment. Flex boxes can adjust in size—either decreasing, to avoid unnecessarily monopolizing space, or increasing to make room for contents to fit within its boundaries. Moreover, the flex layout is less restrictive in terms of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flexion
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatomica ...

Flex (lexical Analyser Generator)
Flex (fast lexical analyzer generator) is a free and open-source software alternative to lex. It is a computer program that generates lexical analyzers (also known as "scanners" or "lexers"). It is frequently used as the lex implementation together with Berkeley Yacc parser generator on BSD-derived operating systems (as both lex and yacc are part of POSIX), or together with GNU bison (a version of yacc) in *BSD ports and in Linux distributions. Unlike Bison, flex is not part of the GNU Project and is not released under the GNU General Public License, although a manual for Flex was produced and published by the Free Software Foundation. History Flex was written in C around 1987 by Vern Paxson, with the help of many ideas and much inspiration from Van Jacobson. Original version by Jef Poskanzer. The fast table representation is a partial implementation of a design done by Van Jacobson. The implementation was done by Kevin Gong and Vern Paxson. Example lexical analyzer This is ...

Apache Flex
Apache Flex, formerly Adobe Flex, is a software development kit (SDK) for the development and deployment of cross-platform rich web applications based on the Adobe Flash platform. Initially developed by Macromedia and then acquired by Adobe Systems, Adobe donated Flex to the Apache Software Foundation in 2011 and it was promoted to a top-level project in December 2012. The Flex 3 SDK was released under the Mozilla Public License, MPL-1.1 license in 2008. Consequently, Flex applications can be developed using standard Integrated development environments (IDEs), such as IntelliJ IDEA, Eclipse (software), Eclipse, the free and open source software, free and open source IDE FlashDevelop, as well as the proprietary Adobe Flash Builder. In 2014, the Apache Software Foundation started a new project called FlexJS to cross-compile ActionScript 3 to JavaScript to enable it to run on browsers that do not support Adobe Flash Player and on devices that do not support the Adobe AIR runtime.

FlexOS
FlexOS is a discontinued modular real-time multiuser computer multitasking, multitasking operating system (RTOS) designed for computer-integrated manufacturing, laboratory, retail and financial markets. Developed by Digital Research's Flexible Automation Business Unit in Monterey, California, Monterey, California, in 1985, the system was considered to become a successor of Digital Research's earlier Concurrent DOS, but with a new, modular, and considerably different system architecture and portability across several processor families. Still named Concurrent DOS 68K and Concurrent DOS 286, it was renamed into FlexOS on 1 October 1986 to better differentiate the target audiences. FlexOS was licensed by several OEMs who selected it as the basis for their own operating systems like 4680 OS, 4690 OS, S5-DOS/MT and others. Unrelated to FlexOS, the original Concurrent DOS system architecture found a continuation in successors like Concurrent DOS XM and Concurrent DOS 386 as well. Ove ...

Flex Linhas Aéreas
Flex Linhas Aéreas, styled as FLEX, was a Brazilian non-regular charter airline based at Rio de Janeiro–Galeão International Airport. It is the brand name of Nordeste Linhas Aéreas S.A., judicial successor of former Viação Aérea Rio-Grandense, known as Varig. Informally Flex is known as "old Varig". The rebranding was necessary because since July 20, 2006 the brand Varig belonged to a different judicial entity. Flex was declared bankrupt on August 20, 2010. History The history of Flex Linhas Aéreas is intimately related to that of Varig, since Flex was the judicial successor of Varig. On 17 June 2005 the airline Varig requested to be placed under bankruptcy protection and to begin a recovery process. The request was granted on 22 June 2005. As part of this process, the airline was divided into two portions, informally known as "old" Varig and "new" Varig. "Old" Varig was judicially known as Viação Aérea Rio-Grandense. "New" Varig, judicially known as VRG Linhas Aér ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FLEX (operating System)
FLEX is a discontinued single-tasking operating system developed by Technical Systems Consultants (TSC) of West Lafayette, Indiana, for the Motorola 6800 in 1976. Overview The original version was distributed on 8" floppy disks; the (smaller) version for 5.25" floppies is called mini-Flex. It was also later ported to the Motorola 6809; that version is called Flex09. All versions are text-based and intended for use on display devices ranging from printing terminals like the Teletype Model 33 ASR to smart terminals. While no graphic displays are supported by TSC software, some hardware supports elementary graphics and pointing devices. FLEX is a disk-based operating system, using 256-byte sectors on soft-sectored floppies; the disk structure uses linkage bytes in each sector to indicate the next sector in a file or free list. The directory structure is simplified as a result. TSC (and others) provide several programming languages including BASIC in two flavors (standard and exten ...

Flex FM
Flex FM is a London-based community radio station, which originally started life as a pirate radio station. Flex broadcasts house, drum and bass, dubstep, UK garage, old skool hardcore, reggae and soul to London and surrounding areas on 101.4FM. History Flex was first established in 1992 as a breakaway station from Don FM and began broadcasting from Merton, South West London, on the frequency of 103.6FM. During that time, it followed the path of a number of other pirates in the capital of playing breakbeat hardcore, through jungle and drum and bass, onto UK garage, until it left the airwaves in 2003. During this first period on-air, DJs, MCs and artists to have played on the station have included DJ Deekline (who scored a number 11 UK chart hit with "I Don't Smoke" in the summer of 2000), MC Hyperactive, the Genius Cru (who had a top 20 UK chart hit with "Boom Selection" in early 2001), Billy Whizz, Lady Sovereign, Ed Rush, DJ Gunshot, Optical, Funky T, Donna Dee, LS, DJ Wise, ...

Flex Temp
Flex temp is a technique used to produce cost savings through increased engine life and reduced overhaul and fuel costs for airliners by allowing them to takeoff, take-off at less than rated thrust. For Airbus and Fokker aircraft the technique is known as ''flex temp'' or just ''flex''. Other manufacturers use the terms ''Assumed temperature thrust reduction'', ''Reduced take-off thrust'' or ''Factored take-off thrust''. Technique The runway length required for an aircraft to take off depends on a number of things including aircraft weight, flap setting and environmental conditions. The particular take-off distance required may be less than the available runway length. In this case a lower thrust may be used. Lower thrust settings increase engine life and reduce maintenance costs. The take-off thrust available from a civil engine is a constant value up to a particular ambient temperature. At this temperature the engine is now running at its turbine temperature limit which is displ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
