Pitch (music)
Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies. Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system. Perception Pitch and frequency Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch (gear)
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch Pine
''Pinus rigida'', the pitch pine, is a small-to-medium-sized pine. It is native to eastern North America, primarily from central Maine south to Georgia and as far west as Kentucky. It is found in environments which other species would find unsuitable for growth, such as acidic, sandy, and low-nutrient soils. Description The pitch pine is irregular in shape, but grows to ). Branches are usually twisted, and it does a poor job at self-pruning. The needles are in fascicles (bundles) of three, about in length, and are stout (over broad) and often slightly twisted. The cones are long and oval, with prickles on the scales. Trunks are usually straight with a slight curve, covered in large, thick, irregular plates of bark. Pitch pine has an exceptionally high regenerative ability; if the main trunk is cut or damaged by fire, it can re-sprout using epicormic shoots. This is one of its many adaptations to fire, which also include a thick bark to protect the sensitive cambium layer from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch (resin)
Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, or plants. Various forms of pitch may also be called tar, bitumen, or asphalt. Pitch produced from plants is also known as resin. Some products made from plant resin are also known as rosin. Uses Pitch was traditionally used to help caulk the seams of wooden sailing vessels (see shipbuilding), and to coat earthenware vessels for the preservation of wine. Pitch may also be used to waterproof wooden containers and in the making of torches. Petroleum-derived pitch is black in colour, hence the adjectival phrase, "pitch-black". The viscoelastic properties of pitch make it well suited for the polishing of high-quality optical lenses and mirrors. In use, the pitch is formed into a lap or polishing surface, which is charged with iron oxide ( Jewelers' rouge) or cerium oxide. The surface to be polished is pressed into the pitch, then rubbed against the surface so formed. The ability ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch Weekly
''The Pitch'' is a free alternative newspaper distributed in the Kansas City Metropolitan Area, including Lawrence and Topeka, Kansas. While known for its investigative stories of the local government, it also covers local sports stories, restaurants, events, visual art, and concerts. It was started in July 1980 as the ''Penny Pitch'', which was a monthly handout at Penny Lane Record Shop in the Westport area of Kansas City. The original editors were Dwight Frizzell and Jay Mandeville. Village Voice Media bought ''The Pitch'' in 1999, and sold the paper in 2011 to SouthComm Communications.

Pitch (film)
''Pitch'' is a 1997 Canadian documentary created by Kenny Hotz and Spencer Rice, featuring themselves as two young filmmakers attending the Toronto International Film Festival to pitch a film concept to various celebrities. Their film idea, titled "The Dawn", concerns a Mafia don who goes for a hernia operation but gets a sex change instead. During the 1996 Toronto fest, they approach Roger Ebert, Norman Jewison (at a packed press conference), Eric Stoltz (leaving a limo), Al Pacino, and others without much success. On a roll, they leave Toronto for Hollywood, getting advice from Arthur Hiller and Neil Simon and finding an agent who expresses interest in their pitch. The film was shown at the 1997 Toronto Film Festival. The film features songs by the Toronto band Phono-Comb Phono-Comb was a Canadian instrumental/modern surf rock group that formed in 1993 in Toronto. History Phono-Comb first materialized when Shadowy Men on a Shadowy Planet played with Jad Fair when he wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seat Pitch
An airline seat is a seat on an airliner in which passengers are accommodated for the duration of the journey. Such seats are usually arranged in rows running across the airplane's fuselage. A diagram of such seats in an aircraft is called an aircraft seat map. Features and amenities Seats are attached to rails underneath the floor which run along the aircraft fuselage. If the airline wants to reconfigure the seating, this is a minor operation. For passenger safety, all airline seats are equipped with seatbelts. Basic amenities Seats are frequently equipped with further amenities. Airline seats may be equipped with a reclining mechanism for increased passenger comfort, either reclining mechanically (usually in economy class and short-haul first and business class) or electrically (usually in long-haul first class and business class). Most aircraft also feature trays for eating and reading, either in the seatback which folds down to form a small table in most economy class se ...

List Of Electronics Package Dimensions
Integrated circuits are put into protective packages to allow easy handling and assembly onto printed circuit boards and to protect the devices from damage. A very large number of different types of package exist. Some package types have standardized dimensions and tolerances, and are registered with trade industry associations such as JEDEC and Pro Electron. Other types are proprietary designations that may be made by only one or two manufacturers. Integrated circuit packaging is the last assembly process before testing and shipping devices to customers. Occasionally specially-processed integrated circuit dies are prepared for direct connections to a substrate without an intermediate header or carrier. In flip chip systems the IC is connected by solder bumps to a substrate. In beam-lead technology, the metallized pads that would be used for wire bonding connections in a conventional chip are thickened and extended to allow external connections to the circuit. Assemblies using " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dot Pitch
Dot pitch (sometimes called line pitch, stripe pitch, or phosphor pitch) is a specification for a computer display, computer printer, image scanner, or other pixel-based devices that describe the distance, for example, between dots ( sub-pixels) on a display screen. In the case of an RGB color display, the derived unit of pixel pitch is a measure of the size of a triad plus the distance between triads. Dot pitch may be measured in linear units (with smaller numbers meaning higher resolution), usually millimeters (mm), or as a rate, for example, dots per inch (with a larger number meaning higher resolution). Closer spacing produces a sharper image (as there are more dots in a given area). However, other factors may affect image quality, including: * Undocumented or inadequately documented measurement method, complicated by ignorance of the existence of different methods * Confusion of pixels and subpixels * Element spacing varying across screen area (e.g., widening in corners c ...

Register File
A register file is an array of processor registers in a central processing unit (CPU). Register banking is the method of using a single name to access multiple different physical registers depending on the operating mode. Modern integrated circuit-based register files are usually implemented by way of fast static RAMs with multiple ports. Such RAMs are distinguished by having dedicated read and write ports, whereas ordinary multiported SRAMs will usually read and write through the same ports. The instruction set architecture of a CPU will almost always define a set of registers which are used to stage data between memory and the functional units on the chip. In simpler CPUs, these ''architectural registers'' correspond one-for-one to the entries in a physical register file (PRF) within the CPU. More complicated CPUs use register renaming, so that the mapping of which physical entry stores a particular architectural register changes dynamically during execution. The register file ...

Pitch (typewriter)
Pitch is the number of (monospaced) letters, numbers and spaces in of , that is, ''characters per inch'' (abbreviated cpi), measured horizontally. The pitch was most often used as a measurement of the size of typewriter fonts as well as those of impact printers used with computers. The most widespread fonts in typewriters are 10 and 12 pitch, called ''Pica'' and ''Elite'', respectively. Both fonts have the same x-height, yielding six lines per vertical inch. There may be other font styles with various width: condensed or compressed (17–20 cpi), italic or bold (10 pitch), enlarged (5–8 cpi), and so on. ''Pica'', the typewriter font, should not be confused with pica, a unit equal to of an inch or twelve points, usually measured vertically. See also * Copyfitting Estimating the average number of characters per line for a proportionately spaced font. * * * Proportional spacingA proportional typeface contains glyph A glyph () is any kind of purposeful mark.
