Virtual Titration Laboratory

The software is designed to emulate potentiometric titration in the Online mode. Virtual Titration allows to conduct laboratory work on analytical chemistry in virtual mode via the Internet. This allows to learn more about different types of titration in a relatively short time and reduce spending on equipment and reagents. The complex software simulates real laboratory work – students drop by drop add a standardized solution of alkali to a solution of acid of unknown concentration. At the same time, a graph on the dependence of pH of the titrated solution on the volume of the added titrant appears on the screen. Analyzing the graph, students should determine the concentration of titrated acid, then the software checks the accuracy of the calculation and informs the students on the mistake in their calculation.

Determination of Combinations on Multipartite Hypergraphs

The software is used to solve a complex problem in graph theory, which consists in finding all combinations in a given hypergraph. With the help of the dynamic programming apparatus, an exhaustive procedure for constructing all possible combinations on a hypergraph is implemented. The software comprises the following modules: module for reading information about the hypergraph – the number of vertices, edges, and the order of partites. The format of this information is a text file in which the parameters of given hypergraph are indicated; module that implements the algorithm for finding combinations in a hypergraph. The software provides output of the software operation results in a text file. The algorithm determines all combinations of a hypergraph that contains no more than 100 edges, which for practical purposes is of a certain interest.
