A computer program (process, task, or thread) may sleep, which places it into an inactive state for a period of time. Eventually the expiration of an interval timer, or the receipt of a signal or interrupt causes the program to resume execution.
A typical sleep system call takes a time value as a parameter, specifying the minimum amount of time that the process is to sleep before resuming execution. The parameter typically specifies seconds, although some operating systems provide finer resolution, such as milliseconds or microseconds.
On Windows, the Sleep()
function takes a single parameter of the number of milliseconds to sleep.
The Sleep()
function is included in kernel32.dll, but no sleep command (executable) is natively available for scripts (batch files). It can be found in collections of Windows utilities like Windows 2003 Resource Kit.
On Unix-like operating systems, the sleep()
function is called providing a single parameter of type unsigned integer of the number of seconds to sleep.
(For more precise sleep times one can use the usleep()
function.)
Conjure One is the self-titled debut album by Canadian electronic music project Conjure One, headed by Rhys Fulber. The album was released in September 2002 (see 2002 in music).
All tracks written by Rhys Fulber, except where noted.
Human sleep and animal sleep (non-human) are a form of rest.
Sleep or Sleeping can also refer to:
Generic term used in the case of polymeric material that may contain other substances
to improve performance and/or reduce costs.
Note 1: The use of this term instead of polymer is a source of confusion and thus is
not recommended.
Note 2: This term is used in polymer engineering for materials often compounded that
can be processed by flow.
Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organics that are malleable and can be molded into solid objects of diverse shapes. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are partially natural.Plasticity is the general property of all materials that are able to irreversibly deform without breaking, but this occurs to such a degree with this class of moldable polymers that their name is an emphasis on this ability.
Due to their relatively low cost, ease of manufacture, versatility, and imperviousness to water, plastics are used in an enormous and expanding range of products, from paper clips to spaceships. They have already displaced many traditional materials, such as wood, stone, horn and bone, leather, paper, metal, glass, and ceramic, in most of their former uses. In developed countries, about a third of plastic is used in packaging and another third in buildings such as piping used in plumbing or vinyl siding. Other uses include automobiles (up to 20% plastic), furniture, and toys. In the developing world, the ratios may be different - for example, reportedly 42% of India's consumption is used in packaging. Plastics have many uses in the medical field as well, to include polymer implants, however the field of plastic surgery is not named for use of plastic material, but rather the more generic meaning of the word plasticity in regards to the reshaping of flesh.
Alanis is the debut studio album by Alanis Morissette, released only in Canada in April 1991 by MCA Records Canada. Morissette recorded the album with Leslie Howe, who also produced her second album Now Is the Time (1992), and it was certified platinum.
John Alexander, head of A&R for MCA Records Canada, first heard a demo tape from Morissette in 1983, when she was nine years old. He called it "very promising. Her voice was very strong, and it was remarkable that the tape included some original songs written by her at that age." However, he decided not to sign her to a record deal because "from an A&R standpoint, I said, 'What am I going to do with a nine-year-old?'" In 1987 Morissette met entertainment manager Stephan Klovan, and at the 1988 World Figure Skating Championships she recorded a well-received version of "O Canada" with two musicians, one of whom was Leslie Howe of the new wave/synthpop duo One to One. Klovan intended for Howe to work with Morissette so that she could audition on the television show Star Search, but eventually both he and Howe decided to try to secure a record contract for her.
