Polymorphism (computer Science)
In programming language theory and type theory, polymorphism is the provision of a single interface to entities of different types or the use of a single symbol to represent multiple different types.: "Polymorphic types are types whose operations are applicable to values of more than one type." The concept is borrowed from a principle in biology where an organism or species can have many different forms or stages. The most commonly recognized major classes of polymorphism are: * ''Ad hoc polymorphism'': defines a common interface for an arbitrary set of individually specified types. * ''Parametric polymorphism'': not specifying concrete types and instead use abstract symbols that can substitute for any type. * ''Subtyping'' (also called ''subtype polymorphism'' or ''inclusion polymorphism''): when a name denotes instances of many different classes related by some common superclass. History Interest in polymorphic type systems developed significantly in the 1960s, with practica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Role-playing Game
A role-playing game (sometimes spelled roleplaying game, RPG) is a game in which players assume the roles of player character, characters in a fictional Setting (narrative), setting. Players take responsibility for acting out these roles within a narrative, either through literal acting or through a process of structured decision-making regarding character development. Actions taken within many games succeed or fail according to a formal role-playing game system, system of rules and guidelines. There are several forms of role-playing games. The original form, sometimes called the tabletop role-playing game (TRPG), is conducted through discussion, whereas in live action role-playing game, live action role-playing (LARP), players physically perform their characters' actions.(Tychsen et al. 2006:255) "LARPs can be viewed as forming a distinct category of RPG because of two unique features: (a) The players physically embody their characters, and (b) the game takes place in a physica ...

Polymorph (novel)
''Polymorph'' is a 1997 cyberpunk novel by American science fiction author Scott Westerfeld Scott David Westerfeld (born May 5, 1963) is an American writer of young adult fiction, best known as the author of the ''Uglies'' and the ''Leviathan'' series. Early life Westerfeld was born in Dallas, Texas. As a child he moved to Connecticu .... Plot "Milica Raznakovic" is the principal alias employed by the protagonist, a shape-changer or "polymorph". Living in a recession-hit future New York, she spends her time partying anonymously, each night in a different body, enjoying casual sex and absolutely no personal attachments. She believes herself to be unique. However, one night she meets another polymorph: older, malicious and much more powerful than herself. The brief and ultimately hostile encounter leads her to place herself in danger by attempting to determine the newcomer's objective, which somehow involves a wealthy industrialist.

Polymorph (Red Dwarf)
"Polymorph" is the third episode of science fiction sitcom ''Red Dwarf'' Series III, and the fifteenth in the series run. It premiered on the British television channel BBC2 on 28 November 1989. It is considered by some to be the series' best.Readers Survey Results, Red Dwarf Smegazine, p. 27., issue 10, December 1992, Fleetway Editions Ltd, Written by Rob Grant and Doug Naylor, and directed by Ed Bye, the episode has the crew fighting a shapeshifting, emotion-stealing creature. It is the only ''Red Dwarf'' episode to feature a pre-credits warning about the content. The episode was re-mastered, along with the rest of the first three series, in 1998.

Shapeshifting
In mythology, folklore and speculative fiction, shape-shifting is the ability to physically transform oneself through an inherently superhuman ability, divine intervention, demonic manipulation, Magic (paranormal), sorcery, Incantation, spells or having inherited the ability. The idea of shape-shifting is in the oldest forms of totemism and shamanism, as well as the oldest existent literature and Epic poetry, epic poems such as the ''Epic of Gilgamesh'' and the ''Iliad''. The concept remains a common literary device in modern fantasy, children's literature and popular culture. Folklore and mythology Popular shape-shifting creatures in folklore are werewolf, werewolves and vampires (mostly of European, Canadians, Canadian, and Native Americans in the United States, Native American/early American origin), Ichchadhari naag and naagin (shape-shifting cobra), ichchadhari naag and ichchadhari naagin (shape-shifting cobras) of India, the huli jing of East Asia (including the ...

Polycaprolactone
Polycaprolactone (PCL) is a biodegradable polyester with a low melting point of around 60 °C and a glass transition temperature of about −60 °C. The most common use of polycaprolactone is in the production of speciality polyurethanes. Polycaprolactones impart good resistance to water, oil, solvent and chlorine to the polyurethane produced. This polymer is often used as an additive for resins to improve their processing characteristics and their end use properties (e.g., impact resistance). Being compatible with a range of other materials, PCL can be mixed with starch to lower its cost and increase biodegradability or it can be added as a polymeric plasticizer to polyvinyl chloride (PVC). Polycaprolactone is also used for splinting, modeling, and as a feedstock for prototyping systems such as fused filament fabrication 3D printers. Synthesis PCL is prepared by ring opening polymerization of ε-caprolactone using a catalyst such as stannous octoate. A wide r ...

Polymorphism (materials Science)
In materials science, polymorphism describes the existence of a solid material in more than one form or crystal structure. Polymorphism is a form of isomerism. Any crystalline material can exhibit the phenomenon. Allotropy refers to polymorphism for chemical elements. Polymorphism is of practical relevance to pharmaceuticals, agrochemicals, pigments, dyestuffs, foods, and explosives. According to IUPAC, a polymorphic transition is "A reversible transition of a solid crystalline phase at a certain temperature and pressure (the inversion point) to another phase of the same chemical composition with a different crystal structure." According to McCrone, polymorphs are "different in crystal structure but identical in the liquid or vapor states." Materials with two polymorphs are called dimorphic, with three polymorphs, trimorphic, etc. Examples Many compounds exhibit polymorphism. It has been claimed that "every compound has different polymorphic forms, and that, in general, the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
