#### Potential Energy in a Gravitational Field 1.0H. Lohninger

Potential energy is stored energy showing various forms of appearance, i.e. gravitational potential energy, elastic, chemical, or electrical potential energy. The energy is stored by doing work against a force such as gravity or the spring in a clockwork motor. Gravitational potential energy is an important form of energy, having much.

#### Central Limit Theorem 1.1H. Lohninger

The central limit theorem is considered to be one of the most important results in statistical theory. It states that means of an arbitrary finite distribution are always distributed according to a normal distribution, provided that the number of observations for calculating the mean is large enough. Usually 10 observations are sufficient to result. Freeware download of Central Limit Theorem 1.1, size 346.03 Kb.

#### Riemann Sum 1.0H. Lohninger

In mathematics, a Riemann sum is a method for approximating the values of integrals. It may also be used to define the integration operation. The sums are named after Bernhard Riemann. There are four different kinds of Riemann sums, called left, right, middle and trapzeoidal sum. Any Riemman sum on a given partition is contained between the lower.

#### Accumulation of Spectra 1.1H. Lohninger

In data acquisition experimenters are often confronted with the unfavourable situation of detecting a signal too small to be recognizable - the signal is embedded into noise which is almost as high as the signal itself, or even higher than it. In order to cope with this situation one has to increase the signal to noise ratio (SNR) to a. Freeware download of Accumulation of Spectra 1.1, size 534.77 Kb.
