Broadcasting

Broadcasting is the distribution of audio and/or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. Broadcasting began with AM radio broadcasting which came into popular use starting with the invention of the crystal detector in 1906. Before this, all forms of electronic communication, radio, telephone, and telegraph, were "one-to-one", with the message intended for a single recipient. The term "broadcasting", borrowed from the agricultural method of sowing seeds in a field by casting them broadly about, was coined by either KDKA manager Frank Conrad or RCA historian George Clark around 1920 to distinguish this new activity of "one-to-many" communication; a single radio station transmitting to multiple listeners.

Over the air Broadcasting is usually associated with radio and television, though in practice radio and television transmissions take place using both wires and radio waves. The receiving parties may include the general public or a relatively small subset; the point is that anyone with the appropriate receiving technology can receive the signal. The field of broadcasting includes a wide range of practices, from relatively private exchanges such as public radio, community radio and commercial radio, public television, and commercial television.

Blaster (Transformers)

Blaster is the name of several fictional characters in the Transformers television and comic series based on the popular toy line produced by Takara Tomy and Hasbro. Due to trademark reasons, he is sometimes called Autobot Blaster. He is an Autobot who specializes in communications.

Transformers: Generation 1

Blaster's initial transformation is an AM/FM Stereo Cassette Player, commonly referred to as a boombox or ghettoblaster, hence the name. Blaster was a popular character from the original series while not featuring as prominently in the modern Transformers universe.

As a member of the Autobot communications sub-group Blaster frequently worked with its other members - Eject, Grand Slam, Raindance, Ramhorn, Rewind and Steeljaw. He is the Autobots' answer to the evil Decepticon Soundwave.

Blaster (Tempo in France, Radiorobot in Italy, Broadcast in Japan), like the Autobot Jazz, has a great love of Earth culture, rock music and other forms of music as long as it is hard. He's normally at the forefront of any given situation. As an AM/FM stereo cassette player, he can perform as a deck, plus receive radio signals on a variety of frequencies. Acting as the Autobot communications center, he can transmit signals within a 4,000 mile radius. Blaster is sometimes depicted as carrying various tape warriors within his deck, including (Steeljaw, Ramhorn, Rewind and Eject).

Broadcast (Cutting Crew album)

Broadcast is the debut album from the English pop/rock band Cutting Crew, released in 1986. It reached #16 on the US charts and #41 on the UK charts. The album was released in Europe with different packaging 8 months before it was released in America. For the American version, 4 tracks were remixed ("Any Colour", "One for the Mockingbird", "I've Been in Love Before" and "(I Just) Died in Your Arms"), all of which were the singles from the album. The current American CD in print is the European version but with the American packaging. It was the first album to be released in the United States by Virgin Records' new American imprint, Virgin Records America.

Broadcast was re-released by Cherry Red Records on May 24, 2010, with bonus tracks including for the 1st time ever on CD "For The Longest Time", the b-side of "(I Just) Died In Your Arms".

Track listing

Trail

A trail is usually a path, track or unpaved lane or road, though the term is also applied, in North America, to routes along rivers, and sometimes to highways. In the United Kingdom and the Republic of Ireland path or footpath is the preferred term for a walking trail. Some trails are single use and can only be used for walking, cycling, horse riding, snow shoeing, cross-country skiing, etc., others, as in the case of a bridleway in the UK, are multi-use, and can be used by walkers, cyclists and equestrians.

There are also unpaved trails used by dirt bikes and other off road vehicles. In some places, like the Alps, trails are used for moving cattle and other livestock (see transhumance). In the US historically, the term was used for a route into or through wild territory used by emigrants (e.g. the Oregon Trail).

Usage

In Australia, the term track can be used interchangeably with trail, and can refer to anything from a dirt road to an unpaved pedestrian path. The term trail gained popularity during World War II, when many servicemen from the United States were stationed in Australia, which probably influenced its being adopted by elements of the Australian media at the time (see Kokoda Track).

Bicycle and motorcycle geometry

Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase, steering axis angle, fork offset, and trail. These parameters have a major influence on how a bike handles.

Wheelbase

Wheelbase is the horizontal distance between the centers (or the ground contact points) of the front and rear wheels. Wheelbase is a function of rear frame length, steering axis angle, and fork offset. It is similar to the term wheelbase used for automobiles and trains.

Wheelbase has a major influence on the longitudinal stability of a bike, along with the height of the center of mass of the combined bike and rider. Short bikes are much more suitable for performing wheelies and stoppies.

Steering axis angle

The steering axis angle, also called caster angle, is the angle that the steering axis makes with the horizontal or vertical, depending on convention. The steering axis is the axis about which the steering mechanism (fork, handlebars, front wheel, etc.) pivots. The steering axis angle usually matches the angle of the head tube.
