Dynamic Range Compression
Dynamic range compression (DRC) or simply compression is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or ''compressing'' an audio signal's dynamic range. Compression is commonly used in sound recording and reproduction, broadcasting, sound reinforcement system, live sound reinforcement and some instrument amplifiers. A dedicated electronic hardware unit or audio software that applies compression is called a compressor. In the 2000s, compressors became available as software plugins that run in digital audio workstation software. In recorded and live music, compression parameters may be adjusted to change the way they affect sounds. Compression and limiting are identical in process but different in degree and perceived effect. A limiter is a compressor with a high #Ratio, ratio and, generally, a short #Attack and release, attack time. Compression is used to improve performance and clarity in public address ...

Companding
In telecommunications and signal processing, companding (occasionally called compansion) is a method of mitigating the detrimental effects of a channel with limited dynamic range. The name is a portmanteau of the words compressing and expanding, which are the functions of a compander at the transmitting and receiving ends, respectively. The use of companding allows signals with a large dynamic range to be transmitted over facilities that have a smaller dynamic range capability. Companding is employed in telephony and other audio applications such as professional wireless microphones and analog recording. How it works The dynamic range of a signal is compressed before transmission and is expanded to the original value at the receiver. The electronic circuit that does this is called a compander and works by compressing or expanding the dynamic range of an analog electronic signal such as sound recorded by a microphone. One variety is a triplet of amplifiers: a logarithmic a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serial Attached SCSI
In computing, Serial Attached SCSI (SAS) is a point-to-point serial Communications protocol, protocol that moves data to and from Computer storage, computer-storage devices such as hard disk drives, solid-state drives and tape drives. SAS replaces the older Parallel SCSI (Parallel Small Computer System Interface, usually pronounced "scuzzy" ) bus technology that first appeared in the mid-1980s. SAS, like its predecessor, uses the standard SCSI command, SCSI command set. SAS offers optional compatibility with Serial ATA (SATA), versions 2 and later. This allows the connection of SATA drives to most SAS backplanes or controllers. The reverse, connecting SAS drives to SATA backplanes, is not possible. The T10 technical committee of the International Committee for Information Technology Standards (INCITS) develops and maintains the SAS protocol; the SCSI Trade Association (SCSITA) promotes the technology. Introduction A typical Serial Attached SCSI system consists of the following ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turboexpander
A turboexpander, also referred to as a turbo-expander or an expansion turbine, is a centrifugal or axial-flow turbine, through which a high-pressure gas is expanded to produce work that is often used to drive a compressor or generator. Because work is extracted from the expanding high-pressure gas, the expansion is approximated by an isentropic process (i.e., a constant-entropy process), and the low-pressure exhaust gas from the turbine is at a very low temperature, −150 °C or less, depending upon the operating pressure and gas properties. Partial liquefaction of the expanded gas is not uncommon. Turboexpanders are widely used as sources of refrigeration in industrial processes such as the extraction of ethane and natural-gas liquids (NGLs) from natural gas, the liquefaction of gases (such as oxygen, nitrogen, helium, argon and krypton) and other low-temperature processes. Turboexpanders currently in operation range in size from about 750 W to about 7.5 MW (1 hp to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expander Graph
In graph theory, an expander graph is a sparse graph that has strong connectivity properties, quantified using vertex, edge or spectral expansion. Expander constructions have spawned research in pure and applied mathematics, with several applications to complexity theory, design of robust computer networks, and the theory of error-correcting codes. Definitions Intuitively, an expander graph is a finite, undirected multigraph in which every subset of the vertices that is not "too large" has a "large" boundary. Different formalisations of these notions give rise to different notions of expanders: ''edge expanders'', ''vertex expanders'', and ''spectral expanders'', as defined below. A disconnected graph is not an expander, since the boundary of a connected component is empty. Every connected finite graph is an expander; however, different connected graphs have different expansion parameters. The complete graph has the best expansion property, but it has largest possible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Micro Expander
The Micro Expander Model 1 (also known simply as the Expander and sold in Europe as the PAL) is an S-100 bus, S-100-based microcomputer introduced by Micro-Expander, Inc., in 1981. The computer was the brainchild of Lee Felsenstein, designer of the Sol-20, the first home computer. After his primary client and marketers of the Sol-20, Processor Technology, went out of business in 1979, Felsenstein founded a new company, Micro-Expander, Inc., in 1980. He gained the capital to sell his prototype of a successor to the Sol-20 as the Micro Expander Model 1 with help from some Swedish investors, primarily Mats Ingemanson, who was hired to market the computer. Specifications The Micro Expander Model 1 is a microcomputer with a built-in, full-sized keyboard complete with a Numeric keypad, numeric keypad, two programmable function keys, and four cursor keys. The Expander measures and features a form factor identical to the Sol-20, but without the walnut side panels. The Expander is built o ...

Expander (song)
"Expander" is a 1994 song by British electronic music group The Future Sound of London The Future Sound of London (often abbreviated FSOL) is a British electronic music duo composed of Garry Cobain and Brian Dougans. They have been described as a "boundary-pushing" electronic act, covering techno, ambient music, ambient, house ..., taken from their 1992 album, '' Accelerator''.

Orthodontic Expander
A palatal expander is a device in the field of orthodontics which is used to widen the upper jaw (maxilla) so that the bottom and upper teeth will fit together better. This is a common orthodontic procedure. The use of an expander is most common in children and adolescents 8–18 years of age. It can also be used in adults, although expansion is more uncomfortable and takes longer in adults. A patient who would rather not wait several months for the end result achieved by a palatal expander may be able to opt for a surgical separation of the maxilla. Use of a palatal expander is most often followed by braces to then straighten the teeth. Palate expanders are a useful tool in expanding the airway due to previous dental extractions. It is believed that expansion therapy should be started in patients either before or during their peak growth spurt. To obtain maximal skeletal changes, the therapy is typically initiated at a very early age. Expansion therapy performed after the peak g ...

Disclosure Widget
A disclosure widget, expander, or disclosure triangle is a graphical control element that is used to show or hide a collection of "child" widgets in a specific area of the interface. The widget hides non-essential settings or information and thus makes the dialog less cluttered. The disclosure widget may be ''expanded'' or ''collapsed'' by the user; when this occurs, the containing window may be expanded to accommodate the increased space requirement. The state of the widget is often signified by a label with a triangle next to it, pointing sideways when it is collapsed and downward when it is expanded (corresponding to the widget's current state), or a button with an arrow pointing downward when it is collapsed and upward when it is expanded (corresponding to how the widget will change state if the button is clicked). Some disclosure widgets can appear as a plus button when collapsed and a minus button when expanded. In some implementations, the widget may be able to remember ...
