List of One Tree Hill characters

One Tree Hill is an American television series created by Mark Schwahn for The WB in 2003. After its third season, The WB and UPN merged to form The CW, which then became the broadcaster for the show in the United States. Schwahn served as executive producer while also writing and directing for the show, including the premieres and finales of all seasons.

The show began with nine main characters in its first season. After that, characters from that first season left the show, with new main characters having been both written in and out of the series. Originally, it followed two half-brothers Lucas and Nathan Scott who started out as enemies but later formed a close bond as brothers. It also followed the brothers' various relationships with other female leads during their high-school years and in their early twenties. The series ultimately spanned nearly fifteen years across nine seasons, with various time jumps taken into account.

Casting

Chad Michael Murray was the first person to be cast for One Tree Hill. The producers were originally unsure as to who Murray would play. Series creator Mark Schwahn wanted him to play the character of Nathan Scott since Murray had played a bad guy several times before, he felt it was only natural to give him this role. Murray, however, wanted to portray Lucas due to a connection he felt with the character. He felt that he could inhabit the character as the two share several similarities. Murray's mother left him when he was young, and Lucas was abandoned by his father. Murray's passion for the role led the producers to cast him as Lucas. Murray had turned down the lead role of Ryan Atwood in The O.C. to accept the role of Lucas Scott.James Lafferty was later cast in the role of Nathan as he was a great basketball player.

Nicki (singer)

Nicki (born Doris Andrea Hrda on November 2, 1966 in the town of Plattling (in the Deggendorf district of Bavaria, Germany) is a German pop singer and composer. She currently lives with her life partner and their two daughters in Plattling.

Career

Hrda grew up with three brothers and two sisters in Plattling. In 1982, she was at a talent competition when producer/songwriter Gog Seidl discovered her and signed her to a record contract. Her stage name of "Nicki" was thought up by pop star Sandra (of Enigma fame).

In 1983, she released her first single, Servus, mach's gut, a hit in the Bavarian dialect. Shortly after, in 1984, she released her first full-length album, Servus Nicki. Throughout her singing career, Nicki remained loyal to the Bavarian dialect. She had numerous other titles with great success, including So a Wunder, Wegen Dir, Mei Schönster Traum, I Bin a Bayerisches Cowgirl, Samstag Nacht, Doch die Zeit Bleibt Steh'n, and Du Bist in Meiner Macht.

The musical range of the 4'11" singer includes styles like rock, calypso, Motown - Soul, Synthpop and even country music. Nicki's biggest hits were composed by Harald Steinhauer, with lyrics by Helmut Frey.

Realisation (metrology)

The realisation of a unit of measure is the conversion of its definition into reality. The International vocabulary of metrology identifies three distinct ways in which this is done - the first being the realisation of a measurement unit from its definition, the second the reproduction of measurement standards and the third the process of actually adopting a particular artefact as a standard.

In the case of the International System of Units, realisation techniques for the base units base are maintained by the International Bureau of Weights and Measures

Overview

The Oxford English Dictionary defines the word "realise" (also spelt "realize") as "to convert (something imagined, planned, etc.) into real existence or fact." The International vocabulary of metrology identifies three distinct ways in which this is done - the first being the realisation of a measurement unit from its definition, the second the reproduction of measurement standards and the third the process of actually adopting a particular artefact as a standard.

Realization (systems)

Realization, in the system theory context refers to a state space model implementing a given input-output behavior. That is, given an input-output relationship, a realization is a quadruple of (time-varying) matrices such that

with describing the input and output of the system at time .

LTI System

For a linear time-invariant system specified by a transfer matrix, , a realization is any quadruple of matrices such that .

Canonical realizations

Any given transfer function which is strictly proper can easily be transferred into state-space by the following approach (this example is for a 4-dimensional, single-input, single-output system)):

Given a transfer function, expand it to reveal all coefficients in both the numerator and denominator. This should result in the following form:

The coefficients can now be inserted directly into the state-space model by the following approach:

This state-space realization is called controllable canonical form (also known as phase variable canonical form) because the resulting model is guaranteed to be controllable (i.e., because the control enters a chain of integrators, it has the ability to move every state).
