Rounding
Rounding or rounding off is the process of adjusting a number to an approximate, more convenient value, often with a shorter or simpler representation. For example, replacing $ with $, the fraction 312/937 with 1/3, or the expression √2 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 false precision, misleadingly precise reporting of a computed number, measurement, or estimate; for example, a quantity that was computed as but is known to be accuracy and precision, 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 whe ...

Cartridge (firearms)
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance ( smokeless powder, black powder substitute, 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 convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge. A cartridge without a projectile is called a '' blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that ...

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 us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Round (boxing)
Boxing is a combat sport and martial art. Taking place in a boxing ring, it involves two people – usually wearing protective equipment, such as protective gloves, hand wraps, and mouthguards – throwing punches at each other for a predetermined amount of time. Although the term "boxing" is commonly attributed to western boxing, in which only fists are involved, it has developed in different ways in different geographical areas and cultures of the World. In global terms, "boxing" today is also 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 these variants are the 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. Humans have engaged in hand ...

Round (music)
A round (also called a perpetual canon 'canon perpetuus'' round about or infinite canon) is a musical composition, a limited type of canon, in which multiple voices sing exactly the same melody, but with each voice beginning at different times so that different parts of the melody coincide in the different voices, but nevertheless fit harmoniously together. It is one of the easiest forms of part singing, as only one line of melody need be learned by all singers, and is part of a popular musical tradition. They were particularly favoured in glee clubs, which combined amateur singing with regular drinking. The earliest known rounds date from 12th-century Europe. One characteristic of rounds is that, "there is no fixed ending", in the sense that they may be repeated as many times as possible, although many do have "fixed" endings, often indicated by a fermata. " Row, Row, Row Your Boat" is a well-known children's round for four voices. Other well-known examples are " Frère ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Round Number
A round number is an integer that ends with one or more "0 (number), 0"s (zero-digit) in a given Radix, 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 Interval (mathematics), 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 649, all of which would ''ro ...

Round (cryptography)
In cryptography, a round or round function is a basic transformation that is repeated (iteration, iterated) multiple times inside the algorithm. Splitting a large algorithmic function into rounds simplifies both implementation and cryptanalysis. For example, encryption using an oversimplified three-round cipher can be written as C = R_3(R_2(R_1(P))), where is the ciphertext and is the plaintext. Typically, rounds R_1, R_2, ... are implemented using the same function, parameterized by the round constant and, for block ciphers, the ''round key'' from the key schedule. Parameterization is essential to reduce the self-similarity of the cipher, which could lead to slide attacks. Increasing the number of rounds "almost always" protects against differential cryptanalysis, differential and linear cryptanalysis, as for these tools the effort grows exponentially with the number of rounds. However, increasing the number of rounds does not ''always'' make weak ciphers into strong ones, as s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Round Steak
A round steak is a beef steak from the "round", the rear end 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 marinated when grilled, and prepared with slow moist-heat methods indoors such as braising, to tenderize the meat and maintain moisture. The cut is typically sliced thin for serving, and is popular as jerky. The rump cover or picanha, with its thick layer of accompanying fat, is highly esteemed in many South American countries, particularly Brazil and Argentina, but is rarely found elsewhere. Topside and silverside British cuts topside and silverside together are roughly equivalent to the Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Rounds
Grand rounds are a methodology of medical education and inpatient care, consisting of presenting the medical problems and treatment of a particular patient to an audience consisting of doctors, pharmacists, residents, and medical students. It was first conceived by clinicians as a way for junior colleagues to round on patients. The patient was traditionally present for the round and would answer questions; grand rounds have evolved with most sessions rarely having a patient present and being more like lectures. An actor portrays the patient in some instances. Grand rounds help doctors and other healthcare professionals keep up to date in important evolving areas which may be outside of their core practice. Most departments at major teaching hospitals will have their own specialized, often weekly, grand rounds. Attending grand rounds is also an important supplement to medical school and on-the-job resident training. Grand rounds can also be distinguished from rounds which is th ...

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 se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
