Cellular concrete wall products (foam concrete, autoclaved aerated concrete and silicate gas) are one of the most demanded building materials. These products are used both in low-rise (cottage) construction and in enclosing self-supporting structures of monolithic frame buildings. The expansion of the possibilities of using cellular concretes is associated with the creation of a new ...

We present a study of the frequency of occurrence of quasi-periodic fluctuations (QPFs) of microwave
radiation from solar active regions at the pre-flare stage. We used correlation curves obtained with the
Nobeyama Radioheliograph (NoRH). We analyzed 529 flares of classes X, M, and C (according to the GOES
classification). In a significant number of considered events (approximately 75% ...

Abstract. The article discusses ways to solve engineering problems in the study of technological processes using methods of system analysis. The essence of this method is to study the technology as a cybernetic system with an assessment of the" reactions” of this system to external influences formed during an active experiment. At the same time, ...

The dynamics of the preflare phase of microwave and ultraviolet emission for M-class X-ray flares in three active regions (ARs), two flares with coronal mass ejections (CMEs) and one flare without a CME, were considered. Extrapolation of the magnetic field in the AR corona showed that eruptive events were associated with the formation of a ...

We present a study of the spatial distribution of quasi-periodic oscillations (QPOs) of microwave emission in three solar active regions before flares. The following events are considered: SOL2011-09-06T01:50M5.3, SOL2011-09-25T02:33M4.4, and SOL2012-07-08T04:19C6.6. Daily observations on the Nobeyama Radioheliograph at a frequency of 17 GHz are used. In all three cases, pre-flare trains of the QPOs of ...

To date, observational signs that determine the ability of solar active region to cause an eruption of matter into the high layers of the solar corona (CME) are not entirely clear. This makes it difficult to understand the physical mechanism of the CME trigger. This paper presents a search for observational signs that may indicate ...

In this study, a comparative analysis was carried out on the preflare and flare conditions for six flares accompanied by coronal mass ejections (CMEs) and five events not accompanied by CMEs. All of the events occurred in the period 2011–2014. The features of the spatial dynamics of microwave emission of active regions (data from the ...

mode with a cadence of ten seconds and ten seconds averaging. We computed the
time series of maximum brightness ...
