Luke Vibert is a British recording artist and producer known for his work in many subgenres of electronic music. Vibert began his musical career as a member of the Hate Brothers, only later branching out into his own compositions. Vibert has recorded under several different aliases, most notably Plug and Wagon Christ.
Vibert's first musical output was in a variety of bands, including a punk act called Five Minute Fashion and later a Beastie Boys-esque group called the Hate Brothers, but he quickly moved into the low-cost environment of solo electronic composition. Although Vibert originally had no intention of ever releasing any of the recordings, his reputation as a creative young voice in his field created a demand for his work.
Vibert originally became involved in electronic music through his interest in hip-hop as well as the environment of bedroom experimentalism associated with the swelling late 1980s UK dance scene.
Plugs are a popular type of hard-bodied fishing lure. They are widely known by a number of other names depending on the country and region. Such names include crankbait, wobbler, minnow, shallow-diver and deep-diver. The term minnow is usually used for long, slender, lures that imitate baitfish, while the term plug is usually used for shorter, deeper-bodied lures which imitate deeper-bodied fish, frogs and other prey. Shallow-diver and deep-diver refer to the diving capabilities of the lure, which depends on the size and angle of the lip, and lure buoyancy.
The concept of an attractant tied to the end of a line to entice fish goes back to prehistoric peoples, but the modern concept of the plug lure is attributed to James Heddon, a beekeeper from Dowagiac, Michigan, who was whittling a piece of wood one day in the late 19th century while relaxing alongside a millpond. When he rose to leave, he tossed the carved scrap of wood into the pond, and a large bass struck at it as it wobbled down through the water. Intrigued by this, Heddon began experimenting and perfected a design he dubbed the "Lucky 13" — a plug that is still sold today. By the early 20th century, many companies were in the business of designing and selling plug lures.
A plug, also known as reconciling amount, is an unsupported adjustment to an accounting record or general ledger. Ideally, bookkeeping should account for all numbers during reconciliation, i.e. when comparing two sets of accounting records to make sure they are in agreement. However, discrepancies, i.e. unintentional accounting errors can occur, for example due to data entry, or an adding or a rounding error. An organization may use a plug for an immaterial amount, because it may not be cost effective to search through numerous pages of transactions to find the error. The acceptability of a plug depends upon the amount: a plug must be immaterial in order to be justified.
Plugging is defined as "the use of false numbers in financial ledgers that forces balances, and effectively masks accounting errors and control deficiencies". Dependence on plugging has been described as "indicative of a dysfunctional finance and accounting system".
Accounting malpractice at the US Defense Department was investigated in 2013 by Reuters. At the Defense Finance and Accounting Service (DFAS) superiors ordered accountants to make unsubstantiated change actions and enter false numbers. In the Cleveland DFAS office, unsupported adjustments to make balances agree totaled $1.03 billion in 2010 alone, according to a December 2011 GAO report.
In baseball, a pitch is the act of throwing a baseball toward home plate to start a play. The term comes from the Knickerbocker Rules. Originally, the ball had to be literally "pitched" underhand, as with pitching horseshoes. Overhand throwing was not allowed until 1884.
The biomechanics of pitching have been studied extensively. The phases of throwing include windup, early cocking, late cocking, early acceleration, late acceleration, deceleration, and follow-through.
Pitchers throw a variety of pitches, each of which has a slightly different velocity, trajectory, movement, hand position, wrist position and/or arm angle. These variations are introduced to confuse the batter in various ways, and ultimately aid the defensive team in getting the batter or baserunners out. To obtain variety, and therefore enhance defensive baseball strategy, the pitcher manipulates the grip on the ball at the point of release. Variations in the grip cause the seams to "catch" the air differently, thereby changing the trajectory of the ball, making it harder for the batter to hit.
Flight dynamics is the study of the performance, stability, and control of vehicles flying through the air or in outer space. It is concerned with how forces acting on the vehicle influence its speed and attitude with respect to time.
In fixed-wing aircraft, the changing orientation of the vehicle with respect to the local air flow is represented by two critical parameters, angle of attack ("alpha") and angle of sideslip ("beta"). These angles describe the vector direction of airspeed, important because it is the principal source of modulations in the aerodynamic forces and moments applied to the aircraft.
Spacecraft flight dynamics involve three forces: propulsive (rocket engine), gravitational, and lift and drag (when traveling through the earths or any other celestial atmosphere). Because aerodynamic forces involved with spacecraft flight are very small, this leaves gravity as the dominant force.
Aircraft and spacecraft share a critical interest in their orientation with respect to the earth horizon and heading, and this is represented by another set of angles, "yaw," "pitch" and "roll" which angles match their colloquial meaning, but also have formal definition as an Euler sequence. These angles are the product of the rotational equations of motion, where orientation responds to torque, just as the velocity of a vehicle responds to forces. For all flight vehicles, these two sets of dynamics, rotational and translational, operate simultaneously and in a coupled fashion to evolve the vehicle's state (orientation and velocity) trajectory.
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 can only be determined in sounds that have a frequency that is clear and stable enough to distinguish from noise. 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.
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 the two are not equivalent. Frequency is an objective, scientific attribute that can be measured. Pitch is each person's subjective perception of a sound, which cannot be directly measured. However, this does not necessarily mean that most people won't agree on which notes are higher and lower.
