Uma roda-gigante
de raio 14 m gira em torno de um eixo horizontal. Um passageiro sentado em uma
cadeira, move-se com velocidade linear v=7 m/s. Determine:
a) a velocidade angular do
movimento.
b) o módulo da aceleração
centrípeta do passageiro.
c) em quanto tempo o
passageiro executa uma volta completa.

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.

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.

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 :)

If the Higher Education Numbers Are Increased then the group decision making ability of society would be raised above that of a middle teenager as it is now
BUT
Governments can control children by using bad parenting techniques, pandering to the pleasure principle, so they will make higher education more and more difficult as they are doing
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 !!!
Experience means little if you don't have enough brain to analyse it
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.
The kind of children who would vote for King Kong who can hold a girl in one hand and swat fighter jets out of teh sky off the tallest building, doesn't have a brain cell or thought to call his own but has a nice smile and offers little girls sweets.

S-Curve + Delay for Bell Curve Showing Erlang Distribution
Generation of Bell Curve from Initial Market through Delay in Pickup of Customers
This provides the beginning of an Erlang distribution model
The Erlang distribution is a two parameter family of continuous probability distributions with support . The two parameters are:
- a positive integer 'shape'
- a positive real 'rate' ; sometimes the scale , the inverse of the rate is used.
