Burr (crater)
Asgard is the second largest multi-ringed basin (large impact crater) on Jupiter's moon Callisto. It is named after Asgard, the realm of the gods in Norse mythology Norse, Nordic, or Scandinavian mythology is the body of myths belonging to the North Germanic peoples, stemming from Old Norse religion and continuing after the Christianization of Scandinavia, and into the Nordic folklore of the modern per .... The central part of Asgard is dominated by the domed Doh impact crater. A smaller multi-ring structure is superposed on the northern part of Asgard. It is called Utgard (also from Norse mythology) and measures around in diameter. Utgard is the fourth largest multi-ring feature on Callisto. A substantial part of the central region of Utgard is covered with deposits from the relatively young Burr crater.

Burr (edge)
A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process. It is usually an unwanted piece of material and is removed with a deburring tool in a process called 'deburring'. Burrs are most commonly created by machining operations, such as grinding, drilling, milling, engraving or turning. It may be present in the form of a fine wire on the edge of a freshly sharpened tool or as a raised portion of a surface; this type of burr is commonly formed when a hammer strikes a surface. Deburring accounts for a significant portion of manufacturing costs. In the printmaking technique of drypoint, burr, which gives a rich fuzzy quality to the engraved line, is highly desirable—the great problem with the drypoint medium is that the burr rapidly diminishes after as few as ten impressions are printed. Types There are three types of burrs that can be formed from machining operations: ''Poisson burr'', ''rollover burr'', and ''breako ...

Burr Truss
The Burr Arch Truss—or, simply, Burr Truss or Burr Arch—is a combination of an arch and a ''multiple kingpost'' truss design. It was invented in 1804 by Theodore Burr, patented on April 3, 1817, and used in bridges, usually covered bridges. Design The design principle behind the Burr arch truss is that the arch should be capable of bearing the entire load on the bridge while the truss keeps the bridge rigid. Even though the kingpost truss alone is capable of bearing a load, this was done because it is impossible to evenly balance a dynamic load crossing the bridge between the two parts. The opposite view is also held, based on computer models, that the truss performs the majority of the load bearing and the arch provides the stability. Either way, the combination of the arch and the truss provides a more stable bridge capable of supporting greater weight than either the arch or truss alone.

Burr Puzzle
A burr puzzle is an interlocking puzzle consisting of notched sticks, combined to make one three-dimensional, usually symmetrical unit. These puzzles are traditionally made of wood, but versions made of plastic or metal can also be found. Quality burr puzzles are usually precision-made for easy sliding and accurate fitting of the pieces. In recent years the definition of "burr" is expanding, as puzzle designers use this name for puzzles not necessarily of stick-based pieces. History The term "burr" is first mentioned in a 1928 book by Edwin Wyatt, but the text implies that it was commonly used before. The term is attributed to the finished shape of many of these puzzles, resembling a seed burr. The origin of burr puzzles is unknown. The first known record appears in a 1698 engraving used as a title page of Chambers's Cyclopaedia. Later records can be found in German catalogs from the late 18th century and early 19th century. There are claims of the burr being a Chinese inventio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burr Distribution
In probability theory, statistics and econometrics, the Burr Type XII distribution or simply the Burr distribution is a continuous probability distribution for a non-negative random variable. It is also known as the Singh–Maddala distribution and is one of a number of different distributions sometimes called the "generalized log-logistic distribution". It is most commonly used to model household income, see for example: Household income in the U.S. and compare to magenta graph at right. The Burr (Type XII) distribution has probability density function: : \begin f(x;c,k) & = ck\frac \\ ptf(x;c,k,\lambda) & = \frac \left( \frac \right)^ \left + \left(\frac\right)^c\right \end and cumulative distribution function: :F(x;c,k) = 1-\left(1+x^c\right)^ :F(x;c,k,\lambda) = 1 - \left + \left(\frac\right)^c \right Related distributions * When ''c'' = 1, the Burr distribution becomes the Pareto Type II (Lomax) distribution. * When ''k'' = 1, the Burr distr ...

Butch Cut
A brush cut is a type of haircut in which the hair on the top of the head is cut short in every dimension. The top and the upper portion of the back and sides are cut the same length, generally between , following the contour of the head. The hair below the upper portion of the sides and back of the head is tapered short or semi-short with a clipper, in the same manner as a crew cut. A variant form may have a slight graduation of the top hair longer from back to front or a quickly graduated bit of hair at the front hairline to achieve a little flip up of the hair at the forehead. A brush that is cut at less than inch on top may be referred to as a burr. A brush that is cut at inch or longer on top, and especially one that shows natural curl, depending on length, may be referred to as a short brush cut or brush cut. Brush cuts are traditionally groomed with hair control wax, commonly referred to as brush wax. See also *Buzz cut ** Crew cut ***Ivy League **Flattop ...

It was grown for the first time by the American Albert Burrage in 1927, and named after him. In recent years the botanical classification of many orchid genera have been changed. In Genera ''Orchidacearum'' (AM Pridgeon, PJ Cribb, FN Rasmussen, MW Chase) the genera ''Cochlioda'' and ''Odontoglossum'' have mostly been merged to ''Oncidium''. Five species of the original ''Miltonia'' now belong to ''Miltoniopsis''. The result is that most of the x ''Burrageara'' hybrids should be called x ''Oncidopsis'' (''Miltoniopsis'' x '' Oncidium'') or x ''Miltonidium'' (''Miltonia ''Miltonia'', abbreviated Milt. in the horticultural trade, is an orchid genus c ...

Borr
In Norse mythology, Borr or BurrThe ''Konungsbók'' or ''Codex Regius'' MS of the ''Völuspá'' reads ''Búrr''; the Hauksbók MS reads ''Borr''. Cf. Nordal (1980:31). The latter form alone was used by 13th-century historian and poet Snorri Sturluson. Cf. Simek (1988:54). (Old Norse: 'son', born;Lindow (2001:90). Thorpe interprets the names ''Buri'' and ''Bör'' to signify 'the producing' or 'the bringer forth' and 'the produced' or 'the brought forth' respectively, linking both to Sanskrit ''bâras'', Gothic ''baurs'', Latin ''por'', ''puer''. Cf. Thorpe (1851:4; 141-2). sometimes anglicized Bor, Bör or Bur) was the son of Búri. Borr was the husband of Bestla and the father of Odin, Vili and Vé. Borr receives mention in a poem in the ''Poetic Edda'', compiled in the 13th century from earlier traditional material, and in the ''Prose Edda'', composed in the 13th century by Icelander Snorri Sturluson. Scholars have proposed a variety of theories about the figure. Attestation Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burl
A burl (American English) or burr (British English) is a tree growth in which the grain has grown in a deformed manner. It is commonly found in the form of a rounded outgrowth on a tree trunk or branch that is filled with small knots from dormant buds. Burl formation is typically a result of some form of stress such as an injury or a viral or fungal infection. Burls yield a very peculiar and highly figured wood sought after in woodworking, and some items may reach high prices on the wood market. Poaching of burl specimens and damaging the trees in the process poses a problem in some areas. Description A burl results from a tree undergoing some form of stress. It may be caused by an injury, virus or fungus. Most burls grow beneath the ground, attached to the roots as a type of malignancy that is generally not discovered until the tree dies or falls over. Such burls sometimes appear as groups of bulbous protrusions connected by a system of rope-like roots. Almost all burl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burr (cutter)
Burrs or burs (sometimes called rotary files) are small cutting tools; not to be confused with small pieces of metal formed from cutting metal, used in die grinders, rotary tools, or dental drills. The name may be considered appropriate when their small-sized head (3 mm diameter shaft) is compared to a bur (fruit seed with hooks) or their teeth are compared to a metal burr. Description Burrs are a rotary analog to files that cut linearly (hence their alternate name, rotary files). They are also in many ways comparable to endmills and to router bits; a distinction is that the latter usually have their toolpath controlled by the machine, whereas burrs are often used freehand. However, there is substantial overlap in the use and toolpath control of these various classes of cutters, and in the outcomes accomplished with them. For example, endmills can be used in routers, and burrs can be used like endmills in milling by CNC or manual machine tool A machine tool is a ...
