Potential Energy in a Gravitational Field 1.0 H. Lohninger 

Multimedia \ Drawing and CAD

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 1.1 H. Lohninger 

Multimedia \ Drawing and CAD

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 1.0 H. Lohninger 

Multimedia \ Drawing and CAD

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 1.1 H. Lohninger 

Multimedia \ Drawing and CAD

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.

Ion Lenses 1.2 H. Lohninger 

Multimedia \ Drawing and CAD

Electron and ion optics are used in a wide variety of applications, from the electron microscope to mass spectrometers and ion propulsion engines. Though the implementaion of a high-quality ion optical system can be rather demanding, the principles of ion optics are simple: any charged particle moves along the gradient of an elecrostatic field,.

LinConG 1.2 H. Lohninger 

Multimedia \ Drawing and CAD

Computer languages usually offer a command to create random numbers. The generation of random numbers, however, is not an easy task for a computer, since the computer is a deterministic machine with no built-in randomness. Thus it is impossible to create true random numbers without any additional hardware. What can be done, is to create. Freeware download of LinConG 1.2, size 335.54 Kb.
