  1. Scoring chance

    orphan date May 2010 A scoring chance , in ice hockey is an attempt, or chance for a team or holder of the puck to score a goal. While there is no exact definition of a scoring chance, the Elias Sports Bureau , who is the official statistics recorder of the National Hockey League and many other professional sports leagues, clarifies a scoring chance as an attempt or shot taken from a home plate shaped area that goes from the top of the faceoff circles, through the faceoff dots, then angled to the goal posts. Another possible definition of a scoring chance can be any shot that is taken by an attacking team on an odd man rush, such as a 2 on 1 or 3 on 2 break. A reason many box scores and stat sheets list the number of scoring chances is to differentiate between shots that are relatively easy saves for the goaltender shots that are not scoring chances and shots that are not easy saves shots that are also scoring chances .

  1. Ridit scoring

    orphan date January 2012 In econometrics , ridit scoring is a statistical method used to analyze ordered qualitative measurements. The tools of ridit analysis were developed and first applied by Bross, ref Bross, Irwin D.J. 1958 How to Use Ridit Analysis, Biometrics , 14 1 18 38 jstor 2527727 ref who coined the term ridit by analogy with other statistical transformations such as probit and logit . Calculation of ridit scores Choosing a reference data set Since ridit scoring is used to compare two or more sets of ordered qualitative data, one set is designated as a reference against which other sets can be compared. In econometric studies, for example, the ridit scores measuring taste survey answers of a competing or historically important product are often used as the reference data set against which taste surveys of new products are compared. Absent a convenient reference data set, an accumulation of pooled data from several sets or even an artificial or hypothetical set can be used. Determining the probability function After a reference data set has been chosen, the reference data set must be converted to a probability function. To do this, let x sub 1 sub , x sub 2 sub , x sub n sub denote the ordered categories of the preference scale. For each j , x sub j sub represents a choice or judgment. Then, let the probability function p be defined with respect to the reference data set as math p j Prob x j . math Determining ridits The ridit scores, or simply ridits, of the reference data set are then easily calculated as math w j 0.5p j sum k j p k . math Each of the categories of the reference data set are then associated with a ridit score.

  1. Scoring A Century

    refimprove date March 2010 notability date March 2010 Scoring A Century is an opera with music by English composer David Blake composer David Blake . The libretto was written by Opera Director Keith Warner . It is described as a low entertainment for highbrows, or vice versa . It tells the history of Mr and Mrs Jedermann, a couple of song and dance merchants, and incidentally of the twentieth century too. The Jedermanns stumble through the momentous events, politics and social change of the last one hundred years, never ageing and only begrudgingly developing. Their sole aim is to provide some songs and snatches, to raise a laugh or provoke a tear. The form the piece adopts is more that of musical comedy than opera . It is a modern Singspiel , a review of a century in nineteen panels. There is dialogue and songs, but from time to time the action is interrupted by through composed mini operas which contain the serious, imaginative heart of the show. Performance History Scoring a Century was originally conceived as part of the millennium celebrations. Scenes from the work were premiered by the University of York Music Department in November 1999 whilst the complete work was being lined up to debut at Portland Opera , Oregon . Just as plans were beginning to finalise, however, the US suffered the 9 11 terrorist attacks . After 9 11, American opera houses immediately lost their budgets and Portland Opera decided to do Boh mes and Magic Flutes instead, Blake says.

Once a street contest, it has now moved to a field named The Pasture across the River Aln from Alnwick Castle . The match involves about 150 men on either side and is a contest between the parishes of St Michael and St Paul. The goals are decorated with greenery and stand about 400 yards apart. Legend has it that it was never a ball but a scotsmans head that was kicked about The original game started with the ball being sent over the Barbican of the Castle to the crowd assembled below. It was then kicked through the streets of the town. Occasionally the game went towards Bondgate Tower and from there to the pastures. In consequence of danger arising from kicking the ball through the town the game within the town was discontinued in 1825 and has since been confined to the pastures. Nowadays the ball is fetched from the castle in procession, preceded by the Duke of Northumberland s piper. The game is won by whichever team is first to score 2 hales or goals, after which the ball is carried to the river and thrown in. Whoever manages to get it out at the far side of the river is allowed to keep the ball, but they have to swim the River Aln to get it.

Explanation In a conflicts lawsuit, one or more Jurisdiction area state law s will be relevant to the decision making process. If the laws are the same, this will cause no problems, but if there are substantive differences, the choice of which law to apply will produce a different Judgment law judgment . Each state therefore produces a set of rules to guide the choice of law, and one of the most significant rules is that the law to be applied in any given situation will be the proper law . This is the law which seems to have the closest and most real connection to the facts of the case, and so has the best claim to be applied.

  1. Strictly proper

    Unreferenced date December 2009 In control theory , a strictly proper transfer function is a transfer function where the Degree mathematics degree of the numerator is less than the degree of the denominator. Example The following transfer function is not strictly proper math textbf G s frac textbf N s textbf D s frac s 4 n 1 s 3 n 2 s 2 n 3 s n 4 s 4 d 1 s 3 d 2 s 2 d 3 s d 4 math because math deg textbf N s 4 nless deg textbf D s 4 math . The following transfer function however, is strictly proper math textbf G s frac textbf N s textbf D s frac n 1 s 3 n 2 s 2 n 3 s n 4 s 4 d 1 s 3 d 2 s 2 d 3 s d 4 math because math deg textbf N s 3 deg textbf D s 4 math . Implications A strictly proper transfer function will approach zero as the frequency approaches infinity. math textbf G pm j infty 0 math which is true for all physical processes. Also, the integral of the real part of a strictly proper transfer function is zero.

  1. Proper length

    For the cosmological notion of proper distance Comoving distance In relativistic physics, proper length is an invariant physics invariant measure of the distance between two spacelike separated Spacetime Basic concepts event s, or of the length of a spacelike Path topology path within a spacetime . The measurement of lengths is more complicated in the theory of relativity than in classical mechanics . In classical mechanics, lengths are measured based on the assumption that the locations of all points involved are measured simultaneously. But in the theory of relativity, the notion of Relativity of simultaneity simultaneity is dependent on the observer. Proper lengths provide an invariant measure, whose value is the same for all observers. Proper length is analogous to proper time . The difference is that proper length is the invariant spacetime interval interval of a spacelike path or pair of spacelike separated events, while proper time is the invariant interval of a timelike path or pair of timelike separated events. Proper length between two events In special relativity , the proper ... at opposite ends of an object, the proper length of the object is the length of the object as measured by an observer which is at rest relative to the object. In any inertial frame of reference, the proper ... zero value for L . Proper length of a path The above formula for the proper length between two events ..., possible to define the proper length of a Path topology path in any spacetime, curved or flat. In a flat spacetime, the proper length between two events is the proper length of a straight path between ... relativity geodesic between two events, so the proper length of a straight path between two events would not uniquely define the proper length between the two events. Along an arbitrary spacelike path P , the proper length is given in tensor syntax by the line integral math L c int P sqrt g mu nu dx ..., or that uses Geometrized unit system geometrized units .
