The work is devoted to methods for increasing the energy efficiency of photovoltaic modules. Various algorithms for determining the maximum power points and their application to obtain the maximum possible efficiency when using solar panels are considered. The principles of the operation of algorithms are described; their advantages and disadvantages are indicated. Their comparison was carried out according to the main significant parameters. The most suitable algorithm for application at a weather station has been selected.

The analysis of the process of electroosmotic water depletion in soils surrounding the track structure of the underground is given. It is established that due to the fact that the structure of soils is disturbed during the construction of the underground, the electroosmotic water loss in them has its own peculiarities, therefore it is necessary to optimize the process by the criterion of specific energy inputs for mass transfer.

Thee paper analyzes the electric traction network and its features. The article shows that the use of one type of protection creates dead zones. To ensure reliability of the protection system, along with the maximum pulse protection system, digital terminal should be used.

The article touches upon the issues of the application of clustering technique and computer vision in order to identify additional parameters in image analysis. In addition to simple recognition of objects, it is possible to determine the specific components of the object of observation, for example, in humans it is: arms, hands and feet. Image clustering gives room for creating algorithms for the recognition of the actions of people. For example, if there is a fight between two people on the street, then using the obtained images from a video camera, it will be possible to inform the police that a fight is at a particular address or to identify potentially dangerous actions as well as an aggressor in an automated mode.

Nowadays the systems for routing are well distributed. However, they all involve routing along existing roads. The article considers the options for the construction of transport routes over cross country, taking into account the technical characteristics of vehicles. The information in this article can be used to solve the problem of the creation of the software designed to develop an optimal route for the movement of technical equipment, taking into account a wide range of features of movement on the ground. In addition, the article discusses possible options for the improvement of modern navigation systems.
