Rounding
Rounding means replacing a number with an approximate value that has a shorter, simpler, or more explicit representation. For example, replacing $ with $, the fraction 312/937 with 1/3, or the expression with . Rounding is often done to obtain a value that is easier to report and communicate than the original. Rounding can also be important to avoid misleadingly precise reporting of a computed number, measurement, or estimate; for example, a quantity that was computed as but is known to be accurate only to within a few hundred units is usually better stated as "about ". On the other hand, rounding of exact numbers will introduce some round-off error in the reported result. Rounding is almost unavoidable when reporting many computations – especially when dividing two numbers in integer or fixed-point arithmetic; when computing mathematical functions such as square roots, logarithms, and sines; or when using a floating-point representation with a fixed number of significan ...

Roundedness
In phonetics, vowel roundedness is the amount of rounding in the lips during the articulation of a vowel. It is labialization of a vowel. When a ''rounded'' vowel is pronounced, the lips form a circular opening, and ''unrounded'' vowels are pronounced with the lips relaxed. In most languages, front vowels tend to be unrounded, and back vowels tend to be rounded. However, some languages, such as French, German and Icelandic, distinguish rounded and unrounded front vowels of the same height (degree of openness), and Vietnamese distinguishes rounded and unrounded back vowels of the same height. Alekano has only unrounded vowels. In the International Phonetic Alphabet vowel chart, rounded vowels are the ones that appear on the right in each pair of vowels. There are also diacritics, and , to indicate greater and lesser degrees of rounding, respectively. Thus has less rounding than cardinal , and has more (closer to the rounding of cardinal ). These diacritics can also be used wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labialization
Labialization is a secondary articulatory feature of sounds in some languages. Labialized sounds involve the lips while the remainder of the oral cavity produces another sound. The term is normally restricted to consonants. When vowels involve the lips, they are called rounded. The most common labialized consonants are labialized velars. Most other labialized sounds also have simultaneous velarization, and the process may then be more precisely called labio-velarization. In phonology, labialization may also refer to a type of assimilation process. Occurrence Labialization is the most widespread secondary articulation in the world's languages. It is phonemically contrastive in Northwest Caucasian (e.g. Adyghe), Athabaskan, and Salishan language families, among others. This contrast is reconstructed also for Proto-Indo-European, the common ancestor of the Indo-European languages; and it survives in Latin and some Romance languages. It is also found in the Cushitic and E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rounded Rectangle
A squircle is a shape intermediate between a square and a circle. There are at least two definitions of "squircle" in use, the most common of which is based on the superellipse. The word "squircle" is a portmanteau of the words "square" and "circle". Squircles have been applied in design and optics. Superellipse-based squircle In a Cartesian coordinate system, the superellipse is defined by the equation \left, \frac\^n + \left, \frac\^n = 1, where and are the semi-major and semi-minor axes, and are the and coordinates of the centre of the ellipse, and is a positive number. The squircle is then defined as the superellipse with and . Its equation is: \left(x - a\right)^4 + \left(y - b\right)^4 = r^4 where is the minor radius of the squircle. Compare this to the equation of a circle. When the squircle is centred at the origin, then , and it is called Lamé's special quartic. The area inside the squircle can be expressed in terms of the gamma function as \mathrm = ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roundness (geology)
Roundness is the degree of smoothing due to abrasion of sedimentary particles. It is expressed as the ratio of the average radius of curvature of the edges or corners to the radius of curvature of the maximum inscribed sphere. Measure of roundness Rounding, roundness or angularity are terms used to describe the shape of the corners on a particle (or clast) of sediment. Such a particle may be a grain of sand, a pebble, cobble or boulder. Although roundness can be numerically quantified, for practical reasons geologists typically use a simple visual chart with up to six categories of roundness: *Very angular: corners sharp and jagged *Angular *Sub-angular *Sub-rounded *Rounded *Well-rounded: corners completely rounded This six-fold category characterisation is used in the Shepard and Young comparison chart and the Powers chart but the Krumbein chart has nine categories. Rounding of sediment particles can indicate the distance and time involved in the transportation of the sed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Round (boxing)
Boxing (also known as "Western boxing" or "pugilism") is a combat sport in which two people, usually wearing protective gloves and other protective equipment such as hand wraps and mouthguards, throw punches at each other for a predetermined amount of time in a boxing ring. Although the term "boxing" is commonly attributed to "western boxing", in which only the fists are involved, boxing has developed in various ways in different geographical areas and cultures. In global terms, boxing is a set of combat sports focused on striking, in which two opponents face each other in a fight using at least their fists, and possibly involving other actions such as kicks, elbow strikes, knee strikes, and headbutts, depending on the rules. Some of the forms of the modern sport are western boxing, bare knuckle boxing, kickboxing, muay-thai, lethwei, savate, and sanda. Boxing techniques have been incorporated into many martial arts, military systems, and other combat sports. While hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin (pinfire, now obsolete); or a ...

Round Number
A round number is an integer that ends with one or more " 0"s (zero-digit) in a given base. So, 590 is rounder than 592, but 590 is less round than 600. In both technical and informal language, a round number is often interpreted to stand for a value or values near to the nominal value expressed. For instance, a round number such as 600 might be used to refer to a value whose magnitude is actually 592, because the actual value is more cumbersome to express exactly. Likewise, a round number may refer to a range of values near the nominal value that expresses imprecision about a quantity.Ferson, S., J. O'Rawe, A. Antonenko, J. Siegrist, J. Mickley, C. Luhmann, K. Sentz, A. Finkel (2015). Natural language of uncertainty: numeric hedge words. ''International Journal of Approximate Reasoning'' 57: 19–39. Thus, a value reported as 600 might actually represent any value near 600, possibly as low as 550 or as high as 650, all of which would ''round'' to 600. In decimal notation, a num ...

Round Steak
A round steak is a beef steak from the "round", the rear leg of the cow. The round is divided into cuts including the eye (of) round, bottom round, and top round, with or without the "round" bone (femur), and may include the knuckle (sirloin tip), depending on how the round is separated from the loin. This is a lean cut and it is moderately tough. Lack of fat and marbling makes round dry out when cooked with dry-heat cooking methods like roasting or grilling. Round steak is commonly prepared with slow moist-heat methods including braising, to tenderize the meat and maintain moisture. The cut is often sliced thin, then dried or smoked at low temperature to make jerky. Rump cover, with its thick layer of accompanying fat, is considered one of the best (and most flavorful) beef cuts in many South American countries, particularly Brazil and Argentina. This specific cut does not tend to be found elsewhere, however. Topside and silverside British cuts topside and silverside togethe ...

Round Of Drinks
A round of drinks is a set of alcoholic beverages purchased by one person in a group for that complete group. The purchaser buys the round of drinks as a single order at the bar. In many places it is customary for people to take turns buying rounds. It is a nearly ubiquitous custom in Ireland, the United Kingdom, Canada, New Zealand, and Australia. In Australia and New Zealand it is referred to as shouting. This practice is also customary in many parts of North America, especially in areas where people with cultural roots in Ireland and the UK predominate. A notable exception was the UK State Management Scheme in which treating (i.e. buying a round) was forbidden, from July 1916 until June 1919. Greaves' Rules Greaves' Rules is a set of etiquette guidelines common in the UK for buying rounds of drinks in English public houses. The rules were first defined by William Greaves (April 1938 - November 2017), a London journalist of the defunct ''Today'' newspaper as a Saturday morn ...

Round Shot
A round shot (also called solid shot or simply ball) is a solid spherical projectile without explosive charge, launched from a gun. Its diameter is slightly less than the bore of the barrel from which it is shot. A round shot fired from a large-caliber gun is also called a cannonball. The cast iron cannonball was introduced by a French artillery engineer Samuel J. Besh after 1450; it had the capacity to reduce traditional English castle wall fortifications to rubble. French armories would cast a tubular cannon body in a single piece, and cannonballs took the shape of a sphere initially made from stone material. Advances in gunpowder manufacturing soon led the replacement of stone cannonballs with cast iron ones. Round shot was made in early times from dressed stone, referred to as gunstone (Middle English: ''gunneston''), but by the 17th century, from iron. It was used as the most accurate projectile that could be fired by a smoothbore cannon, used to batter the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
