Gauge (instrument)
In science and engineering, a dimensional gauge or simply gauge is a device used to make measurements or to display certain Physical dimension, 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. Dimensional properties include thickness, gap in space, diameter of materials.Ray Herren, ''Agricultural Mechanics: Fundamentals & Applications'' (2009), p. 109.Barry Hollembeak, ''Today's Technician: Automotive Electricity and Electronics'' (2010). Basic types All gauges can be divided into four main types, independent of their actual use. # Analogue instrument meter with ''analogue display'' ("needles"). Until the later decades the most common basic type. # Digital instrument meter with ''analogue display''. A screen that shows an "analogue meter", commonly used in modern aircraft cockpits, and some hospital equipment etc. # Digital instrument meter ...

Track Gauge
In rail transport, track gauge is the distance between the two rails of a railway track. All vehicles on a rail network must have Wheelset (rail transport), 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 transverse distance be ... [...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 Gauge formed at the beginning of 1991. Members had previously been in the bands Ivy League and Target. Highly regarded in Chicago's northwest suburban punk scene, Gauge 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 ...

Gauge (actress)
Gauge is an American former pornographic actress and feature dancer. Career After having appeared in about 140 movies, Gauge left the pornographic film Pornographic films (pornos), erotic films, adult films, blue films, sexually explicit films, or 18+ films, are films that represent Human sexual activity, sexually WIKT:explicit, explicit subject matter in order to sexual arousal, arouse, fasci ... 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 her as a pornographic actor, word spread among the staff and, when she was set to graduate, no one would sign off on her required hours. Later, while working at a hospital, her boss sexually harassed her and the hospital's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gauge (knitting)
The term "gauge" is used in knitting to describe the fineness size of knitting machines. It is used in both hand knitting and machine knitting. The phrase in both instances refers to the number of stitches per inch rather than the size of the finished article of clothing. The gauge is calculated by counting the stitches (for hand knitting) or needles (on a knitting machine bed) across a number of inches, then dividing by the sample's width in inches. 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). 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 (2.5 cm) increments. The machine's gauge is again measured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 set K is often assumed/picked to have properties, such as being an absorbing disk in X, that guarantee that p_K will be a real-valued seminorm on X. In fact, every seminorm p on X is equal to the Minkowski functional (that is, p = p_K) of any subset K of X satisfying \ \subseteq K \subseteq \ (where all three of these sets are necessarily absorbing in X and the first and last are also disks). Thus every seminorm (which is a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 and therefore are vector bosons. For comparison, the Higgs boson has spin zero and the hypothetical graviton has a spin of 2. 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; and gluons, which carr ...

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 certain 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 under local transformations according to certain smooth families of operations (Lie groups). Formally, the Lagrangian is invariant under these transformations. 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 th ...

French Gauge
The French scale, also known as the French gauge or Charrière system, is a widely used measurement system for the size of catheters. It is commonly abbreviated as Fr but may also be abbreviated as Fg, FR or F, and less frequently as CH or Ch (referencing its inventor, Charrière). However, the term ''gauge'', abbreviated ''G'' or ''ga'', typically refers to the Birmingham gauge for hypodermic needles. The French scale measures and is proportional to the outer diameter of a catheter, with 1 French (Fr) defined as millimeter, making the relationship: 1 mm = 3 Fr. Thus, the outer diameter of a catheter in millimeters can be calculated by dividing the French size by 3. For example, a catheter with a French size of 9 would have an outer diameter of approximately 3mm. While the French scale aligns closely with the metric system, it introduces redundancy and the potential for rounding errors. This metrication problem is further complicated in medical contexts where metric and imperia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Gauge
Variable gauge systems allow railway vehicles to travel between two railways with different track gauges. Vehicles are equipped with variable gauge axles (VGA). The gauge is altered by driving the train through a gauge changer installed at the break of gauge which moves the wheels to the gauge desired. 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 Ukraine is a country in Eastern Europe. It is the List of European countries by area, second-largest country in Europe after Russia, which Russia–Ukraine border, borders it to the east and northeast. Ukraine also borders Belarus to the nor ... (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 Standard gauge) and ...
