Sector, West Virginia
Sector is an unincorporated community in Hampshire County in the U.S. state of West Virginia. It is located along the west bank of the South Branch Potomac River on Fleming-Sector Road (West Virginia Secondary Route 8/3) across the river from the community of Glebe. Sector grew as a result of its operation of a post office and station on the South Branch Valley Railroad in the early 20th century. On the railroad Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a pre ..., it was known as Glebe Station because of its proximity to Glebe. A suspension bridge once connected the two communities via Fleming-Sector Road, but this was repeatedly demolished by a succession of serious floods, most recently in the late 1930s or early 1940s after which it was not rebuilt.

Portal Rendering
In computer-generated imagery and real-time 3D computer graphics, portal rendering is an algorithm for visibility determination. For example, consider a 3D computer game environment, which may contain many polygons, only a few of which may be visible on screen at a given time. By determining which polygons are currently not visible, and not rendering those objects, significant performance improvements can be achieved. A portal system is based on using the partitioning of space to form generalizations about the visibility of objects within those spaces. Regions of map space are divided into polygonal, generally convex, areas called ''zones'', or sometimes ''sectors''. Adjacent zones are linked to one another via shared dividing polygons termed ''portals''. Approaches that precompute visibility for zones are referred to as potentially visible set or ''PVS'' methods. For example, in a computer game such as ''Descent'', the game area might be divided into several zones. These zon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Star Trek Regions Of Space
Several films and episodes of the science fiction franchise '' Star Trek'' are set in distinct astrographical regions of space. Some of these fictional locations exhibit anomalous physical properties; others are defined as sensitive buffer zones under various fictional political accords. This list describes some of the more significant settings for ''Star Trek'' films or story arcs over multiple television episodes. Badlands The Badlands comprise an area of space that appears (or is referenced) in episodes of '' Star Trek: Deep Space Nine'' and '' Star Trek: Voyager''. Located in ''Star Trek''s Alpha Quadrant, the Badlands are characterized by constant plasma storms and funnel clouds. The Maquis use it in several episodes as a meeting or hiding place because of its treacherous navigation. It is also known to harbor some planets hidden within the clouds and nebulae. In "Caretaker", the pilot episode of ''Star Trek: Voyager'', the titular starship pursues a Maquis ship into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foundation Series
The ''Foundation'' series is a science fiction book series written by American author Isaac Asimov. First published as a series of short stories in 1942–50, and subsequently in three collections in 1951–53, for thirty years the series was a trilogy: ''Foundation''; ''Foundation and Empire''; and ''Second Foundation''. It won the one-time Hugo Award for "Best All-Time Series" in 1966. Asimov began adding new volumes in 1981, with two sequels: ''Foundation's Edge'' and ''Foundation and Earth'', and two prequels: ''Prelude to Foundation'' and ''Forward the Foundation''. The premise of the stories is that, in the waning days of a future Galactic Empire, the mathematician Hari Seldon spends his life developing a theory of psychohistory, a new and effective mathematics of sociology. Using statistical laws of mass action, it can predict the future of large populations. Seldon foresees the imminent fall of the Empire, which encompasses the entire Milky Way, and a Dark Age lasting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sector (instrument)
The sector, also known as a proportional compass or military compass, was a major calculating instrument in use from the end of the sixteenth century until the nineteenth century. It is an instrument consisting of two rulers of equal length joined by a hinge. A number of scales are inscribed upon the instrument which facilitate various mathematical calculations. It was used for solving problems in proportion, multiplication and division, geometry, and trigonometry, and for computing various mathematical functions, such as square roots and cube roots. Its several scales permitted easy and direct solutions of problems in gunnery, surveying and navigation. The sector derives its name from the fourth proposition of the sixth book of Euclid, where it is demonstrated that similar triangles have their like sides proportional. Some sectors also incorporated a quadrant, and sometimes a clamp at the end of one leg which allowed the device to be used as a gunner's quadrant. History ...

Sector/Sphere
Sector/Sphere is an open source software suite for high-performance distributed data storage and processing. It can be broadly compared to Google's GFS and MapReduce technology. Sector is a distributed file system targeting data storage over a large number of commodity computers. Sphere is the programming architecture framework that supports in-storage parallel data processing for data stored in Sector. Sector/Sphere operates in a wide area network (WAN) setting. The system was created by Yunhong Gu (the author of UDP-based Data Transfer Protocol) in 2006 and was then maintained by a group of other developers. Architecture Sector/Sphere consists of four components. The security server maintains the system security policies such as user accounts and the IP access control list. One or more master servers control operations of the overall system in addition to responding to various user requests. The slave nodes store the data files and process them upon request. The clients are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disk Sector
In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. Each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs) and 2048 bytes for CD-ROMs and DVD-ROMs. Newer HDDs use 4096-byte (4 KiB) sectors, which are known as the Advanced Format (AF). The sector is the minimum storage unit of a hard drive. Most disk partitioning schemes are designed to have files occupy an integral number of sectors regardless of the file's actual size. Files that do not fill a whole sector will have the remainder of their last sector filled with zeroes. In practice, operating systems typically operate on blocks of data, which may span multiple sectors. Geometrically, the word sector means a portion of a disk between a center, two radii and a corresponding arc (see Figure 1, item B), which is shaped like a slice of a pie. Thus, the ''disk sector'' (Figure 1, item C) refers to the intersection of a ''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
