Proxflyer refers to a family of micro R/C helicopter prototypes based on a dual coaxial counter-rotating rotor concept developed and patented by Norwegian Petter Muren.
 The concept differs from the swashplate designs in conventional helicopter flight controls and enables a helicopter to be passively stable in hover.
 Elimination of the conventional cyclic and collective pitch controls allows for simpler and lighter helicopters to be developed.
 A helicopter based on this design achieves stability without the use of gyroscopes or any form of active stabilization and thus is made up of much fewer parts than other model helicopters.
 The two counter-rotating rotors keep the helicopter very stable relative to the surrounding air.
 Altitude control is performed by varying the speed for both main rotors while Yaw control is achieved by increasing the speed of one rotor and reducing the speed of the other rotor by the same amount.
 A horizontally oriented tail rotor controls the helicopter’s forward or backward movement by shifting its center of lift with respect to the center of gravity (CG).
Ernest in the Army is a 1998 comedy film directed by John R. Cherry III and starring Jim Varney.
 It is the tenth and final film to feature the character of Ernest P. Worrell before Varney's death in February 2000.
 In this film, Ernest joins the Army because he wants to drive large vehicles, but ends up being sent into combat.
 It was shot in Cape Town, South Africa's Koeberg Nature Reserve.
 John Cherry's son, Josh portrayed Corporal Davis.
Equant (or punctum aequans) is a mathematical concept developed by Claudius Ptolemy in the 2nd century AD to account for the observed motion of the planets.
 The equant is used to explain the observed speed change in planetary orbit during different stages of the orbit.
 This planetary concept allowed Ptolemy to keep the theory of uniform circular motion alive by stating that the path of heavenly bodies was uniform around one point and circular around another point.
The Black Horse was a study concept for a proposed winged single-stage to orbit spaceplane that would use aerial refueling to greatly reduce the size of the spacecraft, to about the size of an F-16 Fighting Falcon.
 The original concept was proposed in 1993 by US Air Force Captain Mitchell Burnside Clapp, who was familiar with the Air Force's use of aerial refueling to extend the performance of combat aircraft.
 The concept was further developed by others, including an even smaller concept developed by Robert Zubrin, Black Colt.
 Clapp left the Air Force in 1996 and partnered with Zubrin to form Pioneer Rocketplane, who proposed a slightly larger version known as Pathfinder.
 This has since become the Pathfinder XL concept.
Peer Polity Interaction is a concept in archaeological theory developed by Colin Renfrew and John Cherry, to explain change in society and material culture.
Another Man, Another Chance (Un autre homme, une autre chance, UK title: Another Man, Another Woman) is a 1977 French western film directed by Claude Lelouch.
Minority, and the related concept of "becoming-minor," is a philosophical concept developed by Gilles Deleuze and Félix Guattari in their books "Kafka: Towards a Minor Literature" (1975), "A Thousand Plateaus" (1980), and elsewhere.
 In these texts, they criticize the concept of "majority".
 For Deleuze and Guattari, "becoming-minoritarian" is primarily an ethical action, one of the becomings one is affected by when avoiding "becoming-fascist".
 They argued further that the concept of a "people", when invoked by subordinate groups or those aligned with them, always refers to a minority, whatever its numerical power might be.
 This has inspired some political philosophers, such as Paul Patton and William Connolly, to elaborate on the concept of "becoming-minoritarian" in order to apply it to modern democratic thought.
Andrew Colin Renfrew, Baron Renfrew of Kaimsthorn, FBA, FSA, Hon FSA Scot (born 25 July 1937 in Stockton-on-Tees) is a British archaeologist, paleolinguist and Conservative peer noted for his work on radiocarbon dating, the prehistory of languages, archaeogenetics, and the prevention of looting at archaeological sites.
 He developed the Anatolian hypothesis, which argues that Proto-Indo-European, the reconstructed ancestor of the Indo-European languages, originated approximately 9,000 years ago in Anatolia and moved with the spread of farming throughout the Mediterranean and into Central and Northern Europe.
 This hypothesis contradicted Marija Gimbutas's Kurgan hypothesis, which states that Proto-Indo-European was spread by a migration of peoples from the Pontic-Caspian steppe approximately 6,000 years ago.
In linguistics, stance is the way in which speakers position themselves in relation to the ongoing interaction, in terms of evaluation, intentionality, epistemology or social relations. Different authors have used the concept of stance to refer to the interpretive framework that is at play in an interaction such as irony, or role-playing, others have used the concept of "authorial stance" to describe the way in which authors position themselves relative to their own texts, and another group have used the concept of "interpersonal stance" to describe the way the communicative goals of individual participants shape a communicative interaction.
 Others have drawn on Daniel Dennett's concept of the "intentional stance" to describe the way humans tend to impute intentions and mental states to those with whom they engage in communication.
The Space Exploration Vehicle (SEV) is a modular vehicle concept developed by NASA.
 It would consist of a pressurized cabin that can be mated either with a wheeled chassis to form a rover for planetary surface exploration (on the Moon and elsewhere) or to a flying platform for open space missions such as servicing satellites and missions to near-Earth asteroids.
 The concept evolved from the Lunar Electric Rover (LER) concept, which in turn was a development of the Small Pressurized Rover (SPR) concept.
