ECFS (cable system)

ECFS (East Caribbean Fiber System) is a network of repeaterless fiber optic submarine communications cable that interconnects fourteen (14) eastern Caribbean islands. The cable is 1730 km (1075 mi) in length and runs from the British Virgin Islands to Trinidad in ten (10) segments. It was first installed in September 1995 and is scheduled to be upgraded by Xtera Communications as of April 25, 2013.

System

A system is a set of interacting or interdependent component parts forming a complex/intricate whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.

The term system may also refer to a set of rules that governs structure and/or behavior. Alternatively, and usually in the context of complex social systems, the term is used to describe the set of rules that govern structure and/or behavior.

Etymology

The term "system" comes from the Latin word systēma, in turn from Greek σύστημα systēma: "whole compounded of several parts or members, system", literary "composition".

History

According to Marshall McLuhan,

"System" means "something to look at". You must have a very high visual gradient to have systematization. In philosophy, before Descartes, there was no "system". Plato had no "system". Aristotle had no "system".

In the 19th century the French physicist Nicolas Léonard Sadi Carnot, who studied thermodynamics, pioneered the development of the concept of a "system" in the natural sciences. In 1824 he studied the system which he called the working substance (typically a body of water vapor) in steam engines, in regards to the system's ability to do work when heat is applied to it. The working substance could be put in contact with either a boiler, a cold reservoir (a stream of cold water), or a piston (to which the working body could do work by pushing on it). In 1850, the German physicist Rudolf Clausius generalized this picture to include the concept of the surroundings and began to use the term "working body" when referring to the system.

Physical system

In physics, a physical system is a portion of the physical universe chosen for analysis. Everything outside the system is known as the environment. The environment is ignored except for its effects on itself. In a physical system, a lower probability states that the vector is equivalent to a higher complexity.

The split between system and environment is the analyst's choice, generally made to simplify the analysis. For example, the water in a lake, the water in half of a lake, or an individual molecule of water in the lake can each be considered a physical system. An isolated system is one that has negligible interaction with its environment. Often a system in this sense is chosen to correspond to the more usual meaning of system, such as a particular machine.

In the study of quantum coherence the "system" may refer to the microscopic properties of an object (e.g. the mean of a pendulum bob), while the relevant "environment" may be the internal degrees of freedom, described classically by the pendulum's thermal vibrations.

Cable 14 (Hamilton, Ontario)

Cable 14 is a community channel licensed to Hamilton, Ontario, and is available to cable television subscribers of both Cogeco and Rogers Cable (including the former Mountain and Source systems) in Hamilton, Dunnville, Caledonia, and Cayuga in Haldimand County. The channel is controlled by its parent company TV Hamilton Limited, which is jointly owned by Cogeco and Rogers. Cogeco owns majority interest in the company at 66.7%. The board of directors is made up of representatives of both cable companies.

Programming

The station airs programming of interest and benefit to the community. Programming includes Kiwanis TV Bingo, which is the longest running community television program in Canada. Each year this program raises funds for local charities. In the 2005-06 season, over $250,000 was raised through Kiwanis TV Bingo and went right back to the community. Cable 14 also airs several community sports events, including games played by Hamilton's Mohawk College and McMaster University sports teams.

Duke Union Community Television

Duke Union Community Television (Cable 13) is the Student television station at Duke University in Durham, North Carolina. Cable 13 functions as a portion of the Duke University Union and is one of the first all student-run television stations in the nation. Founded in 1976 by Duke seniors Jed Daly and David Frey, who raised an initial budget of $20,000 from the Sloan Foundation, Cable 13 students have gone on to win four Telly Awards for "excellence in college broadcasting." Although Duke offers no major in communications and Cable 13 has been moderately funded, it was the largest student-run television station in the United States at least until 2003.

Today approximately 100 students work for Cable 13.

In the summer of 2010, Cable 13 was redesigned into a multimedia broadcasting network, and it was renamed Duke Student Broadcasting. The network currently broadcasts multimedia content at www.dukestudentbroadcasting.com.

History

Cable 13 in its first years shot with borrowed equipment and broadcast in black and white. Its early offerings included a Jimmy Buffett performance at Cameron Indoor Stadium, a performance by the Grateful Dead and several live feeds of Duke basketball games. Competing with five other channels at Duke, Cable 13 attracted a segment of the student audience.
