In computer science, an anonymous pipe is a simplexFIFO communication channel that may be used for one-way interprocess communication (IPC). An implementation is often integrated into the operating system's file IO subsystem. Typically a parent program opens anonymous pipes, and creates a new process that inherits the other ends of the pipes, or creates several new processes and arranges them in a pipeline.
Full-duplex (two-way) communication normally requires two anonymous pipes.
Pipelines are supported in most popular operating systems, from Unix and DOS onwards, and are created using the "|" character.
Pipelines are an important part of many traditional Unix applications and support for them is well integrated into most Unix-like operating systems. Pipes are created using the pipesystem call, which creates a new pipe and returns a pair of file descriptors referring to the read and write ends of the pipe. Many traditional Unix programs are designed as filters to work with pipes.
A smoking pipe is a device made to allow the user to inhale or taste smoke or vapor derived from the burning or vaporization of some substance. The most common form of these is the tobacco pipe, which is designed for use with tobacco, although the device itself may be used with many other substances. The pipes are manufactured with a variety of materials, the most common (as the popularity of its use): Briar, Heather, corn, meerschaum, clay, cherry, glass, porcelain, ebonite, acrylic and other more unusual materials. Other kinds of smoking pipes include:
In armed conflict and in daily life, ships have become an integral part of modern commercial and military systems. Fishing boats are used by millions of fishermen throughout the world. Military forces operate vessels for naval warfare and to transport and support forces ashore. Commercial vessels, nearly 35,000 in number, carried 7.4billion tons of cargo in 2007. As of 2011, there are about 104,304 ships with IMO numbers in the world.
Ships were always a key in history's great explorations and scientific and technological development. Navigators such as Zheng He spread such inventions as the compass and gunpowder. Ships have been used for such purposes as colonization and the slave trade, and have served scientific, cultural, and humanitarian needs. After the 16th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to the world population growth.Ship transport has shaped the world's economy into today's energy-intensive pattern.
Ships(SHIPS (シップス),Shippusu) is a Japanese pop group consisting of Shikō Kanai and Takuya Ide. The unit was created mainly for the anime Kirarin Revolution as all members lend voices to characters in the series. They have released two singles and have had two additional tracks appear on Kirarin Revolution compilation albums.
