Distance
Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria (e.g. "two counties over"). Since spatial cognition is a rich source of conceptual metaphors in human thought, the term is also frequently used metaphorically to mean a measurement of the amount of difference between two similar objects (such as statistical distance between probability distributions or edit distance between strings of text) or a degree of separation (as exemplified by distance between people in a social network). Most such notions of distance, both physical and metaphorical, are formalized in mathematics using the notion of a metric space. In the social sciences, distance can refer to a qualitative measurement of separation, such as social distance or psychological distance. Distances in physics and geometry The distance between physical loca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proxemics
Proxemics is the study of human use of space and the effects that population density has on behaviour, communication, and social interaction. Proxemics is one among several subcategories in the study of nonverbal communication, including haptics (touch), kinesics (body movement), vocalics (paralanguage), and chronemics (structure of time). Edward T. Hall, the cultural anthropologist who coined the term in 1963, defined proxemics as "the interrelated observations and theories of humans use of space as a specialized elaboration of culture". In his foundational work on proxemics, ''The Hidden Dimension,'' Hall emphasized the impact of proxemic behavior (the use of space) on interpersonal communication. According to Hall, the study of proxemics is valuable in evaluating not only the way people interact with others in daily life, but also "the organization of space in heirhouses and buildings, and ultimately the layout of heirtowns". Proxemics remains a hidden component of interpers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proximity (2000 Film)
''Proximity'' (typeset as ProXimity) is a 2000 American action thriller film starring Rob Lowe and James Coburn, produced by Overseas Entertainment for Warner Bros. Pictures handling theatrical and TV distribution and Columbia TriStar Home Entertainment for DVD distribution. It is written by Ben Queen and Seamus Ruane and directed by Scott Ziehl. The film is about an escaped prison convict (Lowe) and the head/founder (Coburn) of a support group called "Justice For The Victim's Families" who has his own tragic past and a dark secret. Plot When William Conroy (Rob Lowe) a former college professor is sentenced to life in prison for vehicular manslaughter it seems his life is over. But, when a fellow inmate tells him that in the past two years fourteen inmates have died at the prison, and then turns up dead the next day, Conroy is in more danger than he ever imagined. His suspicions are confirmed when, while on the way to his parole hearing, the van carrying the inmates crashes. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proximity (2020 Film)
''Proximity'' is a 2020 American science fiction drama film directed by Eric Demeusy and starring Ryan Masson, Highdee Kuan and Christian Prentice. ''Proximity'' was released on demand on May 15, 2020, and received mixed reviews from critics. Plot In 1979, Carl, a Lumberjack working in Alaska, is abducted by aliens. In the present day, a computer engineer named Isaac starts a video diary, after a hike in the woods, he encounters a flying saucer and encounters an alien. Three days later he wakes up near the water. He discovers that he is having hallucinations. He visits the doctor and discovers his bone broken with a precise cut. He got the abduction on camera and uploads it to the internet, and it goes viral. The news, media, and government question Isaac. Isaac realizes mysterious signs of alien life throughout history prove that aliens exist, he finds a post on the internet by a girl his age named Sara that includes a similar story, the two meet at a local diner.

Proximity Fuze
A proximity fuze (or fuse) is a Fuze (munitions), fuze that detonates an Explosive material, explosive device automatically when the distance to the target becomes smaller than a predetermined value. Proximity fuzes are designed for targets such as planes, missiles, ships at sea, and ground forces. They provide a more sophisticated trigger mechanism than the common contact fuze or timed fuze. It is estimated that it increases the lethality by 5 to 10 times, compared to these other fuzes. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proximity Sensor
A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a capacitive proximity sensor or photoelectric sensor might be suitable for a plastic target; an inductive proximity sensor always requires a metal target. Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between the sensor and the sensed object. Proximity sensors are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing. This is common in large steam turbines, compressors, and motors that u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proximity Space
In topology, a proximity space, also called a nearness space, is an axiomatization of the intuitive notion of "nearness" that hold set-to-set, as opposed to the better known point-to-set notion that characterize topological spaces. The concept was described by but ignored at the time.W. J. Thron, ''Frederic Riesz' contributions to the foundations of general topology'', in C.E. Aull and R. Lowen (eds.), ''Handbook of the History of General Topology'', Volume 1, 21-29, Kluwer 1997. It was rediscovered and axiomatized by V. A. Efremovič in 1934 under the name of infinitesimal space, but not published until 1951. In the interim, discovered a version of the same concept under the name of separation space. Definition A (X, \delta) is a set X with a relation \delta between subsets of X satisfying the following properties: For all subsets A, B, C \subseteq X # A \;\delta\; B implies B \;\delta\; A # A \;\delta\; B implies A \neq \varnothing # A \cap B \neq \varnothing implies A \; ...
