2008–09 Pittsburgh Penguins seasonThe 2008–09 Pittsburgh Penguins season was the 42nd season of Pittsburgh Penguins in the National Hockey League (NHL). The regular season began with two games against the Ottawa Senators in Stockholm, Sweden on October 4 and October 5, 2008. On February 15, the team had a record of 27–25–5 and was five points out of playoff position. The organization fired head coach Michel Therrien and replaced him with Dan Bylsma, head coach of the organization's American Hockey League affiliate in Wilkes-Barre.
Recurrence plotIn descriptive statistics and chaos theory, a recurrence plot (RP) is a plot showing, for each moment in time, the times at which the state of a dynamical system returns to the previous state at , i.e., when the phase space trajectory visits roughly the same area in the phase space as at time . In other words, it is a plot of showing on a horizontal axis and on a vertical axis, where is the state of the system (or its phase space trajectory). Natural processes can have a distinct recurrent behaviour, e.g.
9th Cavalry Regiment (United States)The 9th Cavalry Regiment is a parent cavalry regiment of the United States Army. It is not related to the 9th Kansas Cavalry Regiment of the Union Army. Historically, it was one of the Army's four segregated African-American regiments and was part of what was known as the Buffalo Soldiers. The regiment saw combat during the Indian and Spanish–American Wars. During Westward Expansion, the regiment provided escort for the early western settlers and maintained peace on the American frontier.
Sollentuna MunicipalitySollentuna Municipality (Sollentuna kommun ˈsɔ̂lːɛnˌtʉːna kʊˈmʉːn) is a municipality in Stockholm County in east-central Sweden, north of Stockholm. Its seat of local government is located in Tureberg, which is a part of Sollentuna urban area. Sollentuna borders the municipalities of Solna, Sundbyberg, Stockholm, Järfälla, Upplands Väsby, Täby and Danderyd in clockwise order starting to the south. Since 1995 the bulk of the built-up area of the municipality is statistically counted to the multimunicipal city of Stockholm.
Recurrence relationIn mathematics, a recurrence relation is an equation according to which the th term of a sequence of numbers is equal to some combination of the previous terms. Often, only previous terms of the sequence appear in the equation, for a parameter that is independent of ; this number is called the order of the relation. If the values of the first numbers in the sequence have been given, the rest of the sequence can be calculated by repeatedly applying the equation. In linear recurrences, the nth term is equated to a linear function of the previous terms.
Li-FiLi-Fi (also written as LiFi) is a wireless communication technology which utilizes light to transmit data and position between devices. The term was first introduced by Harald Haas during a 2011 TEDGlobal talk in Edinburgh. Li-Fi is a light communication system that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of data in visible light.
Recurrence quantification analysisRecurrence quantification analysis (RQA) is a method of nonlinear data analysis (cf. chaos theory) for the investigation of dynamical systems. It quantifies the number and duration of recurrences of a dynamical system presented by its phase space trajectory. The recurrence quantification analysis (RQA) was developed in order to quantify differently appearing recurrence plots (RPs), based on the small-scale structures therein.
Dependent and independent variablesDependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Dependent variables are studied under the supposition or demand that they depend, by some law or rule (e.g., by a mathematical function), on the values of other variables. Independent variables, in turn, are not seen as depending on any other variable in the scope of the experiment in question. In this sense, some common independent variables are time, space, density, mass, fluid flow rate, and previous values of some observed value of interest (e.
Errors-in-variables modelsIn statistics, errors-in-variables models or measurement error models are regression models that account for measurement errors in the independent variables. In contrast, standard regression models assume that those regressors have been measured exactly, or observed without error; as such, those models account only for errors in the dependent variables, or responses. In the case when some regressors have been measured with errors, estimation based on the standard assumption leads to inconsistent estimates, meaning that the parameter estimates do not tend to the true values even in very large samples.
