Gauge (instrument)
A gauge, in science and engineering, is a device used to make measurements or in order to display certain dimensional information. A wide variety of tools exist which serve such functions, ranging from simple pieces of material against which sizes can be measured to complex pieces of machinery. Depending on usage, a gauge can be described as "a device for measuring a physical quantity",Richard Talman, ''Geometric Mechanics'' (2008), p. 255-56: "a "gauge" is a device for measuring a physical quantity—a thermometer is a temperature gauge, a ruler is a length gauge".. for example "to determine thickness, gap in space, diameter of materials, or pressure of flow",Ray Herren, ''Agricultural Mechanics: Fundamentals & Applications'' (2009), p. 109: "A gauge is a device used to determine thickness, gap in space, diameter of materials, or pressure of flow". or "a device that displays the measurement of a monitored system by the use of a needle or pointer that moves along a calibrated scale". ...

Track Gauge
In rail transport, track gauge (in American English, alternatively track gage) is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A '' loading gauge'' is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A ''structure gauge'' specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. Uses of the term The most common use of the term "track gauge" refers to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gauge (band)
Gauge is an American post-hardcore band from the northwest suburbs of Chicago, Illinois. History From the ashes of the bands Ivy League and Target, Gauge formed at the beginning of 1991. Highly regarded in Chicago's northwest suburban punk scene, they inspired and performed with other bands from the same area such as Cap'n Jazz, Friction, and Braid. Gauge released their first full-length, Soothe, by the end of 1992. After releasing their second album in 1994, entitled Fire Tongue Burning Stomach, they announced their break up. A posthumous 10" was released in 1995, making the band's final recordings available. During their career, Gauge played 150 shows. Their final show was on October 6, 1994, at The Moose Lodge in Mount Prospect, IL with Cap'n Jazz and Tetsuo. Members of Gauge went on to perform in the bands Sky Corvair, Euphone, 5ive Style, Sweater Weather, Haymarket Riot, Traluma, Radio Flyer, Heroic Doses, Ambulette and Rollo Tomasi, as well as working with Joan Of Arc, O ...

Gauge (actress)
__NOTOC__ Gauge is an American pornographic actress and feature dancer. Career After having appeared in about 140 movies, Gauge left the pornographic film industry in 2005 due to a contract dispute with her management company. She was certified as a surgical technologist, but she reported that she was often turned down for jobs because of her adult film career. She retrained as a makeup artist, but suffered similar issues. While Gauge was studying to become a surgical technician, an anesthesia student recognized Gauge from her adult film career, word quickly spread through the hospital staff that there was a porn star among their ranks, and, when Gauge was set to graduate, she said that no one at the unnamed hospital would sign off on her required hours. Gauge has also claimed that while "working at a hospital" that her "boss hit on Flirting or coquetry is a social and sexual behavior involving spoken or written communication, as well as body language. It is either to sugges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gauge (knitting)
In knitting, the word gauge is used both in hand knitting and machine knitting; the latter, technical abbreviation GG, refers to knitting machines fineness size. In both cases the term refers to the number of stitches per inch, not the size of the finished garment. The gauge is measured by counting the number of stitches (in hand knitting) or the number of needles (on a knitting machine bed) over several inches; then dividing by the number of inches in the width of the sample. Gauge on knitting machines There are two types of classification of Knitting Gauges or Unit of Measure: *A – Used for Cotton Fully fashion flat machines (Bentley – Monk, Textima, Sheller etc..) where “Gauge” is measured in 1,5” Inches (2,54 cm x 1,5) and the machine's gauge is expressed by the number of needles needed to achieve that gauge. *B – Used for hand, mechanical or modern Electronic Flat Machines (Stoll, Shima, Protti etc..), where gauge is measured in 1 inch increments (or 2,5&nb ...

Minkowski Functional
In mathematics, in the field of functional analysis, a Minkowski functional (after Hermann Minkowski) or gauge function is a function that recovers a notion of distance on a linear space. If K is a subset of a real or complex vector space X, then the or of K is defined to be the function p_K : X \to , \infty valued in the extended real numbers, defined by p_K(x) := \inf \ \quad \text x \in X, where the infimum of the empty set is defined to be positive infinity \,\infty\, (which is a real number so that p_K(x) would then be real-valued). The Minkowski function is always non-negative (meaning p_K \geq 0) and p_K(x) is a real number if and only if \ is not empty. This property of being nonnegative stands in contrast to other classes of functions, such as sublinear functions and real linear functionals, that do allow negative values. In functional analysis, K is usually assumed to have properties (such as being absorbing in X, for instance) that will guarantee that for every ...

Gauge Boson
In particle physics, a gauge boson is a bosonic elementary particle that acts as the force carrier for elementary fermions. Elementary particles, whose interactions are described by a gauge theory, interact with each other by the exchange of gauge bosons, usually as virtual particles. Photons, W and Z bosons, and gluons are gauge bosons. All known gauge bosons have a spin of 1; for comparison, the Higgs boson has spin zero and the hypothetical graviton has a spin of 2. Therefore, all known gauge bosons are vector bosons. Gauge bosons are different from the other kinds of bosons: first, fundamental scalar bosons (the Higgs boson); second, mesons, which are composite bosons, made of quarks; third, larger composite, non-force-carrying bosons, such as certain atoms. Gauge bosons in the Standard Model The Standard Model of particle physics recognizes four kinds of gauge bosons: photons, which carry the electromagnetic interaction; W and Z bosons, which carry the weak interaction; an ...

Gauge Fixing
In the physics of gauge theories, gauge fixing (also called choosing a gauge) denotes a mathematical procedure for coping with redundant degrees of freedom in field variables. By definition, a gauge theory represents each physically distinct configuration of the system as an equivalence class of detailed local field configurations. Any two detailed configurations in the same equivalence class are related by a gauge transformation, equivalent to a shear along unphysical axes in configuration space. Most of the quantitative physical predictions of a gauge theory can only be obtained under a coherent prescription for suppressing or ignoring these unphysical degrees of freedom. Although the unphysical axes in the space of detailed configurations are a fundamental property of the physical model, there is no special set of directions "perpendicular" to them. Hence there is an enormous amount of freedom involved in taking a "cross section" representing each physical configuration ...

Gauge Theory
In physics, a gauge theory is a type of field theory in which the Lagrangian (and hence the dynamics of the system itself) does not change (is invariant) under local transformations according to certain smooth families of operations (Lie groups). The term ''gauge'' refers to any specific mathematical formalism to regulate redundant degrees of freedom in the Lagrangian of a physical system. The transformations between possible gauges, called ''gauge transformations'', form a Lie group—referred to as the ''symmetry group'' or the ''gauge group'' of the theory. Associated with any Lie group is the Lie algebra of group generators. For each group generator there necessarily arises a corresponding field (usually a vector field) called the ''gauge field''. Gauge fields are included in the Lagrangian to ensure its invariance under the local group transformations (called ''gauge invariance''). When such a theory is quantized, the quanta of the gauge fields are called '' gauge bosons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Gauge
The French scale, French gauge or Charrière system is commonly used to measure the size of a catheter. It is most often abbreviated as Fr, but can often be seen abbreviated as Fg, FR or F. It may also be abbreviated as CH or Ch (for Charrière, its inventor). However, simply ''gauge'', ''G'' or ''GA'' generally refers to Birmingham gauge. The Charrière is measured by the ''outer'' diameter, and is defined as 1 Fr = 1/3 mm, and thus 1 mm = 3 Fr; therefore the diameter of a round catheter in millimetres can be determined by dividing the French size by 3., For example, if the French size is 9, the diameter is 9/3 = 3.0; mm. It is seen that the French unit is fully redundant with the metric system but introduces potential for rounding errors. This metrication problem is further complicated by the mixed use of metric and imperial units in medical professions using catheters. An increasing French size corresponds to a larger external diameter. This is contrary to Birmingham gauge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Gauge
A variable gauge system allows railway vehicles in a train to travel across a break of gauge between two railway networks with different track gauges. For through operation, a train must be equipped with special bogies holding variable gauge wheelsets containing a variable gauge axle (VGA). The gauge is altered by driving the train through a gauge changer or gauge changing facility. In effect, the track widens or narrows. As the train passes through the gauge changer, the wheels are unlocked, are moved closer together, or further apart, and are then re-locked. Installed variable gauge systems exist within the internal network of Spain, and are installed on international links between Spain/France (Spanish train), Sweden/Finland (Swedish train), Poland/Lithuania (Polish train) and Poland/Ukraine (Polish train). A system for changing gauge without the need to stop is in widespread use for passenger traffic in Spain, for services run on a mix of dedicated high-speed lines (using St ...
