Após uma enchente, um grupo de pessoas ficou ilhado numa região. Um avião de salvamento, voando horizontalmente a uma altura de 720 m e mantendo uma velocidade de v = 50m/s, aproxima-se do local para que um pacote com medicamentos e alimentos seja lançado para as pessoas isoladas. A que distância, na direção horizontal, o pacote deve ser abandonado para que caia junto às pessoas? Despreze a resistência do ar e adote um g = 10m/s².

Cette simulation est une version optimisée de l'eaurdinateur, dans laquelle on a utilisé l'influence d'un flux sur un autre pour économiser les réservoirs utilisés pour diviser par deux les flux de sortie des portes AND.

Nous n'avons malheureusement pas réussi à changer la couleur de l'état en fonction de sa valeur. Celle-ci peut être changée dans le panneau de configuration, afin de tester des valeurs différentes.

On notera que pour obtenir un résultat correct, deux conditions sont nécessaires:
1°) Il faut attendre que les flux dans les portes se stabilisent, ce qui prend pas moins de 10 secondes (et qui reflète le délai de latence inhérent à tout circuit, qui correspond environ au nombre maximum de portes logiques traversées entre l'entrée et la sortie du circuit.
2°) Il faut utiliser la méthode de simulation basée sur une approximation de Runge-Kutta, sous peine de voir apparaître des oscillations parasites dans certaines portes qui rendent le résultat instable.

​The probability density function (PDF) of the normal distribution or Bell Curve of Normal or Gaussian Distribution is the mean or expectation of the distribution (and also its median and mode). 

The parameter is its standard deviation with its variance then, A random variable with a Gaussian distribution is said to be normally distributed and is called a normal deviate.
However, those who enjoy upskirts are called deviants and have a variable distribution :)

85% of the population has a qualification level equal or below a 12th grader, 17 year old ... the chance of finding someone with any sense is low (~1 in 6) and the outcome of them being chosen by those who are uneducated in the policies they are to decide is even more rare !!!

Democracy is only as good as the ability of the voters to FULLY understand the implications of the policies on which they vote., both context and the various perspectives.   National voting of unqualified voters on specific policy issues is the sign of corrupt manipulation.

Democracy:  Where a group allows the decision ability of a teenager to decide on a choice of mis-representatives who are unqualified to make judgement on social policies that affect the lives of millions.

In diesem Modell wird das Verhalten, also die Positionsänderungen von drei Körpern innerhalb eines Bezugssystems aufgrund der Gravitationskraft simuliert. Je nach Änderung der Parameter (Masse, Ausgangsposition, Radius der Massen(-punkte) ​variiert auch die Chaotizität des System.
Zusätzlich wird als Gedankenexperiment die Reibungskraft die durch ein hypothetisches umgebenes Medium entsteht eingeführt und die Auswirkung auf die Chaotizität gezeigt.
