Friend-to-friend
A friend-to-friend (or F2F) computer network is a type of peer-to-peer network in which users only make direct connections with people they know. Passwords or digital signatures can be used for authentication. Unlike other kinds of private P2P, users in a friend-to-friend network cannot find out who else is participating beyond their own circle of friends, so F2F networks can grow in size without compromising their users' anonymity. Retroshare, WASTE, GNUnet, Freenet and OneSwarm are examples of software that can be used to build F2F networks, though RetroShare is the only one of these configured for friend-to-friend operation by default. Many F2F networks support indirect anonymous or pseudonymous communication between users who do not know or trust one another. For example, a node in a friend-to-friend overlay can automatically forward a file (or a request for a file) anonymously between two friends, without telling either of them the other's name or IP address. These friends ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
P2P Network
Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the network. They are said to form a peer-to-peer network of nodes. Peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. Peers are both suppliers and consumers of resources, in contrast to the traditional client–server model in which the consumption and supply of resources are divided. While P2P systems had previously been used in many application domains, the architecture was popularized by the file sharing system Napster, originally released in 1999. The concept has inspired new structures and philosophies in many areas of human interaction. In such social contexts, peer-to-peer as a meme refers to the egalitarian soc ...

Fédération Aéronautique Internationale
The (; FAI; en, World Air Sports Federation) is the world governing body for air sports, and also stewards definitions regarding human spaceflight. It was founded on 14 October 1905, and is headquartered in Lausanne, Switzerland. It maintains world records for aeronautical activities, including ballooning, aeromodeling, and unmanned aerial vehicles (drones), as well as flights into space. History The FAI was founded at a conference held in Paris 12–14 October 1905, which was organized following a resolution passed by the Olympic Congress held in Brussels on 10 June 1905 calling for the creation of an Association "to regulate the sport of flying, ... the various aviation meetings and advance the science and sport of Aeronautics." The conference was attended by representatives from 8 countries: Belgium (, founded 1901), France ( Aéro-Club de France, 1898), Germany ( aka "German Airship League", founded 1902), Great Britain ( Royal Aero Club, 1901), Italy (, 1904), Spai ...

Model Engine
A model engine is a small internal combustion engine typically used to power a radio-controlled aircraft, radio-controlled car, radio-controlled boat, free flight, control line aircraft, or ground-running tether car model. Because of the square–cube law, the behaviour of many engines does not always scale up or down at the same rate as the machine's size; usually at best causing a dramatic loss of power or efficiency, and at worst causing them not to work at all. Methanol and nitromethane are common fuels. Overview The fully functional, albeit small, engines vary from the most common single-cylinder two-stroke to the exotic single and multiple-cylinder four-stroke, the latter taking shape in boxer, v-twin, inline and radial form, a few Wankel engine designs are also used. Most model engines run on a blend of methanol, nitromethane, and lubricant (either castor or synthetic oil). Two-stroke model engines, most often designed since 1970 with Schnuerle portin ...

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Control Line
Control line (also called U-Control) is a simple and light way of controlling a flying model aircraft. The aircraft is connected to the operator by a pair of lines, attached to a handle, that work the elevator of the model. This allows the model to be controlled in the pitch axis. It is constrained to fly on the surface of a hemisphere by the control lines. The control lines are usually either stranded stainless steel cable or solid metal wires of anywhere from to . Sewing thread or braided fishing line may be used instead of wires, but air resistance is greater. A third line is sometimes used to control the engine throttle, and more lines may be added to control other functions. Electrical signals sent over the wires are sometimes used in scale models to control functions such as retracting undercarriage and flaps. There is also a control system that uses a single solid wire, this is called Monoline. When the pilot twists the wire around its axis, a spiral inside the airpla ...

Model Aircraft
A model aircraft is a physical model of an existing or imagined aircraft, and is built typically for display, research, or amusement. Model aircraft are divided into two basic groups: flying and non-flying. Non-flying models are also termed static, display, or shelf models. Aircraft manufacturers and researchers make wind tunnel models for testing aerodynamic properties, for basic research, or for the development of new designs. Sometimes only part of the aircraft is modelled. Static models range from mass-produced toys in white metal or plastic to highly accurate and detailed models produced for museum display and requiring thousands of hours of work. Many are available in kits, typically made of injection-molded polystyrene or resin. Flying models range from simple toy gliders made of sheets of paper, balsa, card stock or foam polystyrene to powered scale models built up from balsa, bamboo sticks, plastic, (including both molded or sheet polystyrene, and styrofoam) ...

F2F (song)
"F2F" is a song by American singer-songwriter SZA from her second studio album, ''SOS'' (2022). "F2F" is a rock song that draws influence from genres such as country, pop rock, and grunge. SZA wrote the song with Lizzo, who provides background vocals, and producers Rob Bisel and Carter Lang. The song was one of around five rock-inspired songs SZA created for ''SOS'', out of a desire to experiment with various genres outside of her usual R&B music. The song begins with acoustic guitar strums before transitioning into a chorus backed by drums and power chords from electric guitars. The lyrics talk about having sex with someone to cope with breaking up with a former partner. SZA's experimentation with rock on the song was positively received. "F2F" was one of 20 tracks from ''SOS'' that debuted on the US ''Billboard'' Hot 100. Consequently, it became SZA's first song to debut atop ''Billboard'' Alternative Streaming Songs chart. Background and release SZA released her debut s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grumman F2F
The Grumman F2F was a single-engine, biplane fighter aircraft with retractable undercarriage, serving as the standard fighter for the United States Navy between 1936 and 1940. It was designed for both carrier- and land-based operations. Design and development Grumman's success with the two-seat FF-1, which was significantly faster than even the single-seat fighters of its time, resulted in a contract for the single-seat XF2F-1.Jordan, Corey C."Grumman's Ascendency: Chapter Two." ''Planes and Pilots Of World War Two,'' 2000. Retrieved: 22 July 2011. Armed with two .30 caliber (7.62 mm) machine guns above the cowl, the new design also incorporated watertight compartments to reduce weight and improve survivability in the event of a water landing.Cacutt 1989, pp. 155–162. The prototype first flew on 18 October 1933, equipped with the experimental XR-1534-44 Twin Wasp Junior radial engine, and reached a top speed of at – faster than the FF-1 at the same altitude.

Supply Chain Management
In commerce, supply chain management (SCM) is the management of the flow of goods and services including all processes that transform raw materials into final products between businesses and locations. This can include the movement and storage of raw materials, work-in-process inventory, finished goods, and end to end order fulfilment from the point of origin to the point of consumption. Interconnected, interrelated or interlinked networks, channels and node businesses combine in the provision of products and services required by end customers in a supply chain. Supply-chain management has been defined as the "design, planning, execution, control, and monitoring of supply chain activities with the objective of creating net value, building a competitive infrastructure, leveraging worldwide logistics, synchronising supply with demand and measuring performance globally". SCM practice draws heavily on industrial engineering, systems engineering, operations management, logis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
