Linear Regression 2.0
Study the regression problem with this tool. Linear Regression help you analyze the regression problem, most specifically the relationship between the data points and the error surface.On one hand you can learn how to represent a line in two different spaces ({x,y} and {k,d}), and on the other hand you see that solving the regression problem is nothing else than finding the minimum in the error surface.Linear regression can be look at as an...

Distribution diagrams of polyprotic acids 1.0
Study polyprotic acids with this tool. Distribution diagrams of polyprotic acids enable you to calculate the distribution of the dissociated ions of mono-, di-, tri-, and tetra-protic acids. The user can set the pKa values of the protonated species and immediately sees the distribution of the ions in dependence of the pH value.Polyprotic acids are able to donate more than one proton per acid molecule, in contrast to monoprotic acids which...

Fourier Synthesis 1.1
Fourier Synthesis enable you to adjust the first seven coefficients of the Fourier series (both for the cosine and the sine terms). In addition, a few predefined wave forms can be selected.Fourier synthesis represents the summation of cosine and sine waves at different frequencies and amplitudes.

Radiation Diagram of an Antenna Array 1.0
Study antenna array with this tool. Radiation Diagram of an Antenna Array help you study the effects of the number, distance and phase shift of several coupled antennas on the radiation pattern.In wave theory, a phased array is a group of antennas in which the relative phases of the respective signals feeding the antennas are varied in such a way that the impactful radiation pattern of the array is reinforced in a desired direction and...

Linear Regression for Chemical Analysis 2.0
Study linear regression with this tool. Linear Regression for Chemical Analysis help you calculate the regression parameters and the limit of detection for two linear scenarios. The user enters the calibration values into the table at the left and immediately sees the results.Linear regression is a commonly used method to establish a quantitative relationship between two variables (for example, the absorbance at a specific wavelength and the...

Riemann Sum 1.0
Calculate Riemann Sums with this tool. Riemann Sum can calculate the Riemann Sums for various functions. The user may adjust the width of the slices to see the convergence of the Riemann sum towards the actual area under a curve.In addition, the relationship between the width of the slices and the estimation error is displayed.In mathematics, a Riemann sum is a method for approximating the values of integrals. It may also be used to define the...

Analog/Digital Conversion 1.0
Study amplitude resolution with this simulation. Analog/Digital Conversion can display the effects of changing the sampling frequency and / or the amplitude resolution. You may set both parameters and apply the digitization process to various signal forms.The analog signal is continuous in time and it is necessary to convert this to a flow of digital values. It is therefore required to define the rate at which new digital values are sampled...

Travelling Salesman 1.2
Solve the traveling salesman problem with this tool. Travelling Salesman apply a circular Kohonen map to the traveling salesman problem. Users can set up a number of randomly distributed cities (depicted by the little houses), the size of the Kohonen map (the number of "neurons" in the circular network), and a few parameters of the network and the learning algorithm.

Atomic Spectroscopy 1.0
Analyze atomic spectra fast and easy. Atomic Spectroscopy help you analyze atomic spectra. Atomic spectra can be used to quantitatively determine more than 70 chemical elements. In order to be able to detect the atomic spectrum, the atoms or ions have to be separated from one another, for example the atoms have to be in a gaseous state.This can be achieved by massively heating the substances to be determined (typically the temperature is...

Black Body 1.1
Study radiation effect with this tool. Black Body is a small, simple, easy-to-use software specially designed to display this radiation effect.The user can take several snapshots of the radiation spectrum in order to compare the effect at different temperatures.The emission of radiation of a non-reflecting ideal black surface is defined by Planck's radiation law. It states that the emitted radiation power increases with increasing temperature...

Radiation Pattern of two Aerials 1.0
Study antennas with this utility. Radiation Pattern of two Aerials enable you to study the effect of distance and phase shift of two coupled antennas.As the length of a single linear antenna increases, a characteristic deterioration in directivity appears showing so called side lobes.If several antennas are used in parallel, however, directivity is improved due to the increase in antenna surface area. The field of single radiators is additive...
