Zeit²

Zeit² is a scrolling shooter shoot 'em up made by German developer Brightside Games, which was released for Microsoft Windows and Xbox Live Arcade on January 12, 2011. The word "Zeit" is German for time.

Gameplay

Zeit² is a traditional side-scrolling, 2D, shoot-’em-up game with a unique gameplay mechanic that allows players to move forward and backward in time, making it possible for the player to combine shots and power, and even be assisted by a shadow version of the player.

The game features seventy challenges and eight bosses, as well as six game modes, including Score Attack, Survival, Wave, Time Limit and Tactics.

History

Zeit² was within the Top 20 of Microsoft Dream Build Play 2008, an Independent Games Festival 2009 Student Showcase Finalist and Indie Game Challenge 2010 Finalist.

Zeit

Zeit (English: Time) is the third album by the German electronic music group Tangerine Dream. A double LP, it was released in August 1972, being the first release featuring Peter Baumann, who joined then-current members Christopher Franke and Edgar Froese. Zeit is subtitled Largo in Four Movements.

Overview

The style of this album is slower and more atmospheric than their previous albums. Florian Fricke from the Munich-based group Popol Vuh, playing Moog synthesizer, and four cellists appear on the first track. The album cover depicts a solar eclipse.

As explained by Paul Russell for the 2002 reissue, "Zeit, which means 'time', was based on the philosophy that time was in fact motionless and only existed in our own minds." And concluding, "Without doubt Zeit is a Krautrock master work still capable of surprises without having to shock. The album which took the band to the edge of international recognition, still sounds timeless 30 years on."

Music critics often refer to Zeit as being one of the first (or perhaps the first) examples of dark ambient music.

Zeit (song)

"Zeit" ("Time") was the German entry in the Eurovision Song Contest 1997, performed in German by Bianca Shomburg.

The song was performed eleventh on the night, following Spain's Marcos Llunas with "Sin rencor" and preceding Poland's Anna Maria Jopek with "Ale jestem". At the close of voting, it had received 22 points, placing 18th in a field of 25.

The song is a ballad, written and composed by Ralph Siegel and Bernd Meinunger, with Shomburg expressing her regret at "time running through my fingers" and her desire for just a bit more time - with the implication in the lyrics being that this would save a relationship. Shomburg also recorded an English version of the song, entitled "Time".

It was succeeded as German representative at the 1998 Contest by Guildo Horn with "Guildo hat euch lieb!".

Separation (statistics)

In statistics, separation is a phenomenon associated with models for dichotomous or categorical outcomes, including logistic and probit regression. Separation occurs if the predictor (or a linear combination of some subset of the predictors) is associated with only one outcome value when the predictor is greater than some constant.

For example, if the predictor X is continuous, and the outcome y = 1 for all observed x > 2. If the outcome values are perfectly determined by the predictor (e.g., y = 0 when x ≤ 2) then the condition "complete separation" is said to obtain. If instead there is some overlap (e.g., y = 0 when x < 2, but y has observed values of 0 and 1 when x = 2) then "quasi-complete separation" obtains. A 2 × 2 table with an empty cell is an example of quasi-complete separation.

This observed form of the data is important because it causes problems with estimated regression coefficients. Loosely, a parameter in the model "wants" to be infinite, if complete separation is observed. If quasi-complete separation is the case, the likelihood is maximized at a very large but not infinite value for that parameter. Computer programs will often output an arbitrarily large parameter estimate with a very large standard error. Methods to fit these models include exact logistic regression and "Firth" logistic regression, a bias-reduction method based on a penalized likelihood.

Flocking (behavior)

Flocking behavior is the behavior exhibited when a group of birds, called a flock, are foraging or in flight. There are parallels with the shoaling behavior of fish, the swarming behavior of insects, and herd behavior of land animals.

Computer simulations and mathematical models which have been developed to emulate the flocking behaviors of birds can generally be applied also to the "flocking" behavior of other species. As a result, the term "flocking" is sometimes applied, in computer science, to species other than birds.

This article is about the modelling of flocking behavior. From the perspective of the mathematical modeller, "flocking" is the collective motion of a large number of self-propelled entities and is a collective animal behavior exhibited by many living beings such as birds, fish, bacteria, and insects. It is considered an emergent behavior arising from simple rules that are followed by individuals and does not involve any central coordination.

Flocking behavior was first simulated on a computer in 1987 by Craig Reynolds with his simulation program, Boids. This program simulates simple agents (boids) that are allowed to move according to a set of basic rules. The result is akin to a flock of birds, a school of fish, or a swarm of insects.
