Lasers And Their Application In Heating Technology, Khalmanov A., Aymatov R., Omonkulov O., Khudaykulov A. Jan 2020

Lasers And Their Application In Heating Technology, Khalmanov A., Aymatov R., Omonkulov O., Khudaykulov A.

Problems of Architecture and Construction

Heat engineering is one of the common technical subjects that are important for heat engineering, such as heat generation by radiation, light transmission by optical lubricants, and the use of transmitted light energy. Currently, the laser is a powerful light-emitting diet and is based on the radiation generated by the electron transport of a layer of atomic energy.In article, a heat exchanger is considered in the high-temperature region and the laser radiation in heaters exceeds other heat exchange intensities.

Mathematical Calculation On Durability Of Some Constructions In Building, Khusanov B., Fatkhullayev F. Jan 2020

Mathematical Calculation On Durability Of Some Constructions In Building, Khusanov B., Fatkhullayev F.

Problems of Architecture and Construction

In article problems on durability of building constructions are investigated. Using the empirical formula for weight of an arch, under the influence of force, and the extremum theory, critical value of gravity is defined. Further for a homogeneous core which one end is fixed by the hinge, and on the second end force, and depending on a building material and a kind of its form is inserted, there is the greatest value of durability.
