In chaos theory, the butterfly effect is the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a later state.
Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. BGP is classified as a path-vector routing protocol, and it makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator.
A short takeoff and landing (STOL) aircraft has short runway requirements for takeoff and landing. Many STOL-designed aircraft also feature various arrangements for use on runways with harsh conditions. STOL aircraft, including those used in scheduled passenger airline operations, have also been operated from STOLport airfields which feature short runways.
OSCAR is AOL's proprietary instant messaging and presence information protocol. It was used by AOL's AIM instant messaging system and ICQ.
LASIK or Lasik, commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism. LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most people, LASIK provides a long-lasting alternative to eyeglasses or contact lenses.
Japan Airlines Flight 123 was a scheduled domestic Japan Airlines passenger flight from Tokyo's Haneda Airport to Osaka International Airport, Japan. On August 12, 1985, a Boeing 747SR operating this route suffered a sudden decompression 12 minutes into the flight, and crashed in the area of Mount Takamagahara, Ueno, Gunma Prefecture, 100 km from Tokyo 32 minutes later. The crash site was on Osutaka Ridge, near Mount Osutaka.
The voiced alveolar tap or flap is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents a dental, alveolar, or postalveolar tap or flap is ⟨ɾ⟩.
A batting helmet is worn by batters in the game of baseball or softball. It is meant to protect the batter's head from errant pitches thrown by the pitcher. A batter who is "hit by pitch," due to an inadvertent wild pitch or a pitcher's purposeful attempt to hit him or her, may be seriously, even fatally, injured.
Vaginoplasty is any surgical procedure that results in the construction or reconstruction of the vagina. It is a type of genitoplasty. Pelvic organ prolapse is often treated with one or more surgeries to repair the vagina. Sometimes a vaginoplasty is needed following the treatment or removal of malignant growths or abscesses in order to restore a normal vaginal structure and function. Surgery to the vagina is done to correct congenital defects to the vagina, urethra and rectum. It will correct protrusion of the urinary bladder into the vagina (cystocele) and protrusion of the rectum (rectocele) into the vagina. Often, a vaginoplasty is performed to repair the vagina and its attached structures due to trauma or injury. Labiaplasty, which alters the appearance of the vulva, can be performed as a discrete surgery, or as a subordinate procedure within a vaginoplasty.
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed.
The Gurney flap is a small tab projecting from the trailing edge of a wing. Typically it is set at a right angle to the pressure-side surface of the airfoil and projects 1% to 2% of the wing chord. This trailing edge device can improve the performance of a simple airfoil to nearly the same level as a complex high-performance design.
The gracilis muscle is the most superficial muscle on the medial side of the thigh. It is thin and flattened, broad above, narrow and tapering below.
Trabeculectomy is a surgical procedure used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye's trabecular meshwork and adjacent structures. It is the most common glaucoma surgery performed and allows drainage of aqueous humor from within the eye to underneath the conjunctiva where it is absorbed. This outpatient procedure was most commonly performed under monitored anesthesia care using a retrobulbar block or peribulbar block or a combination of topical and subtenon anesthesia. Due to the higher risks associated with bulbar blocks, topical analgesia with mild sedation is becoming more common. Rarely general anesthesia will be used, in patients with an inability to cooperate during surgery.
A split-flap display, or sometimes simply a flap display, is a digital electromechanical display device that presents changeable alphanumeric text, and occasionally fixed graphics.
A dog ear is a folded down corner of a book page. The name refers to the ears of many breeds of domestic dog flapping over. A dog ear can serve as a bookmark. Dog-earing is also commonly used to mark a section or phrase in a book that one finds to be important or of personal meaning. Other names for this practice include page folding and corner turning. The practice is generally frowned upon by those that want to preserve books in their original condition. It is also sometimes used to keep sheets of paper together, in the absence of a stapler or paper clip.
A circulation control wing (CCW) is a form of high-lift device for use on the main wing of an aircraft to increase the maximum lift coefficient. CCW technology has been in the research and development phase for over sixty years. Blown flaps were an early example of CCW.
A human-powered hydrofoil is a small hydrofoil watercraft propelled entirely by the muscle power of its operator(s). Hydrofoils are the fastest water-based vehicles propelled solely by human power. They can reach speeds of up to 34 km/h, easily exceeding the world records set by competitive rowing which stand at about 20 km/h. This speed advantage is achieved since hydrofoils lack a submerged body to provide buoyancy, greatly reducing the drag force.
Krueger flaps, or Krüger flaps, are lift enhancement devices that may be fitted to the leading edge of an aircraft wing. Unlike slats or droop flaps, the main wing upper surface and its nose is not changed. Instead, a portion of the lower wing is rotated out in front of the main wing leading edge. Current Boeing aircraft, and many others, use this design between the fuselage and closest engine, where the wing is thickest. Outboard of the engine, slat flaps are used on the leading edge. The Boeing 727 also used a mix of inboard Krueger flaps and outboard slats, although it had no engine between them. Most early jet airliners, such as the Boeing 707 and Boeing 747, used Krueger flaps only.
The Gouge flap, invented by Arthur Gouge of Short Brothers in 1936, allowed the pilot to increase both the wing area and the chord of an aircraft's wing, thereby reducing the stalling speed at a given weight. This provided the benefit of a shorter takeoff distance for a given load, a shorter distance to achieve a given height and a lower takeoff speed. This type of flap, in spite of its use on successful aircraft such as the Short Sunderland and the Short Stirling, was limited to use on aircraft produced by Short Brothers.
Flap is a 1970 American Western film directed by Carol Reed and starring Anthony Quinn, Claude Akins and Shelley Winters. Set in a modern Native American reservation, it is based on the novel Nobody Loves a Drunken Indian by Clair Huffaker.
