Invariant and invariance may have several meanings, among which are:
An introduction to the difference between time varying and time invariant systems.

This model tests for invariance across genders for the factor structure specified in a measurement model (CFA). The test is done in AMOS for both configural and metric invariance. The Excel tools are available on the homepage of StatWiki. http://statwiki.kolobkreations.com
A retrouver dans son contexte sur www.physagreg.fr Pour calculer un champ électrique en électrostatique, il faut tout d'abord étudier les invariances et symétries de la distribution de charges afin de simplifier l'expression générale du champ recherché. Cette vidéo montre ces différentes étapes : expression générale d'un champ dans différents systèmes de coordonnées, invariances et suppression de coordonnées de dépendance du champ, symétrie et antisymétrie pour éliminer des composantes du champ. Ce sera l'occasion de voir plusieurs exemples, le fil infini ou le condensateur plan.

I keep saying "measurement invariance", but actually what we are testing is a subset of measurement invariance known as "metric invariance". The overall factor structure (configural invariance) have already been established, and now we are looking at invariance of factor loadings, i.e. metric invariance.
A discussion about three critical properties of digital systems: linearity, shift invariance, and causality. This lecture is adapted from the ECE 410: Digital Signal Processing course notes developed by David Munson and Andrew Singer
Design & Gestalt Principle; Invariance Learn the secrets of the 22 Guiding Principles of Design from Closure and Grouping to Multi-Stability and Visual Illusion critical to understanding design and aesthetics. Our minds seek to perceive patterns and elements, combining them into recognizable forms. Missing parts are added to complete recognizable figures, and at times our perception plays tricks on us.
This video explains that a four dimensional volume element is invariant to Lorentz transformation. This question was asked in IAS Exam 2009 (question 1(d)) of 10 marks.

On December 6, 2016, Drs. Caroline Gooden and Zijia Li presented this 40-minute talk at the University of Kentucky on Measurement Invariance with Categorical Indicators in Mplus, the third presentation in the Fall 2016 Applied Quantitative and Psychometric Series (AQPS). This presentation focused on what is and how to conduct a measurement invariance analysis for categorical items within a confirmatory factor analysis framework in Mplus. Visit http://sites.education.uky.edu/apslab/upcoming-events/ to download the PowerPoint Handout and Mplus Data Files for this talk.
This video covers invariance and model fit in a confirmatory factor analysis in amos.
In this talk I will give proofs of some 'invariance principles' in probability; the Central Limit Theorem, the Berry--Esseen Theorem, and multidimensional and higher-degree versions thereof. I will discuss these proofs from a computer science perspective, and show some applications to fields such as property testing, derandomization, learning, and inapproximability.

Les invariants.
Not true
CHORUS
So this is my world
Feel my steel
Evilution
Run to your lives
Hear my noise
Teenage whores
So this is my world
You can scream, but it's useless
This is my world, the chainsaw's law
Friday night, the thirteenth day is coming,
I'm a God behind a mask
Steel sharp claws, Better stay up late
The nightmares return
CHORUS
So this is my world
Feel my steel
Evilution
Run to your lives
Hear my noise
Teenage whores
So this is my world
You can scream, but it's useless
This is my world, the chainsaw's law
Hell inside a box
Zombie
Hide in the dark hills
Brains & fresh meat
Bloody teeth, Naked girls on bed,
Here's comes my love...sweet litle bitch
Slaves of sin
Three sixes in my bed will fuck your destiny
CHORUS
So this is my world
Feel my steel
Evilution
Run to your lives
Hear my noise
Teenage whores
So this is my world
You can scream, but it's useless
This is my world, the chainsaw's law
This is my world ( x4 )
