Abstract: Systems and methods for predicting who is watching a program are disclosed. Text related to the program can be reviewed, the text comprising: plot information, sub-title information, summary information, script information, or synopsis information, or any combination thereof. Pre-determined genre words and pre-determined keywords can be determined based on machine learning analysis of historical programs. Words from the text which are relevant words can be determined, the relevant words being words that help identify genre words or keywords. How closely the relevant words coincide to the pre-determined genre words can be determined by generating a breakdown of how many relevant words are the pre-determined genre words and the pre-determined keywords. It can be predicted who will watch the program based on the breakdown.

Abstract: The invention concerns a metabolic cage (1) for small rodents, comprising: a living chamber (20) designed to receive a rodent; a technical mount (30), said living chamber (20) and said technical mount (30) comprising each complementary nesting elements, enabling the living chamber (20) to be assembled and released relative to the technical mount (30).

Abstract: The present invention provides a method of modeling an optical fiber amplifier, the method being characterized in that it comprises the steps consisting in: establishing (100) the speed equations and the propagation equations of physical phenomena or effects involved in an optical fiber amplifier; obtaining (112) exact analytic solutions for the propagation equations of signals in the fiber, discretizing them, and interpolating them along the fiber; solving (120) the previously discretized speed equations by injecting into them solutions obtained from the propagation equations; and delivering (130) the performance parameters of the fiber in terms of amplification.

Abstract: The invention concerns an injection device for optical fibre characterised in that it comprises a main fibre (100), and an auxiliary fibre (200) whereof the beveled end (210) is placed on the edge of the main fibre (10), wherein the auxiliary fibre (200) has a numerical aperture smaller than the numerical aperture of the main fibre (100). The invention also concerns a method for preparing the device.
