Timely detection and recognition of road signs is very important for motorists and pedestrians. The necessary information is delivered to the driver through the program of direct recognition of road signs. There are different types of road signs, some signs may have multi-directional points to indicate the direction of the location, and some signs are about safety rules and restrictions. can do in the message. Identifying and recognizing road signs is an important practice because it helps the new driver to find the way. We are able to solve these problems through the road sign detection program we created in python. In this program, in the following model, each pixel in the binary matrix is 8 bits, so instead of converting their values to 0 and 1, they can be converted to values between 0 and 255. In this way, 128x128 pixel images are converted into binary matrices, and these matrices are prepared for high-level data acquisition models, for example, the CNN model.

The purpose of the research is development of production technology of silica brick with improved adhesion strength of mortar on the basis of local raw materials.
Scientific novelty of research consists in the following:
the possibility of production of silicate brick with the use of solid waste of soda production, such as sludge distillation slurry, siftings of carbonaceous materials and the waste of slaked lime as a microfiller is shown;
it has been determined that the chemical processes occurring between the silicate bricks containing solid waste of soda production and calcium aluminates of cement clinker, with the formation of hydrocarbonate calcium ЗСаО-АЬОз-СаСОз-1 IH2O, firmly binds the crystals of calcium hydroxide with calcium carbonate increase on the adhesion strength of silica brick with cement mortar;
scientific basis for using polymincral rocks tuffit Karmana field as hydraulically active additives to the silica bricks, high activity for a specified taffeta on the absorption of Са(ОН)г from lime solution have been developed;
it is revealed that the increase of the adhesion strength of silica brick obtained on the base of the limestone-tuffit binder is the result of the content in silicate brick residual active silica and metakaolinite firmly linking of calcium hydroxide masonry mortar and the resulting crystalline intergrowths growths on the brick surface, increase adhesion to mortar solutions;
rational composition and technology of production of silica bricks with high construction and technical characteristics on the basis of composite limc-silica binder with solid waste of soda production, as well as limc-tufctulov binder has been developed.
