The article presents the current state of the available stock of guided air weapons and the problem of transition of guided air weapons to operation according to technical condition. The transfer of guided air weapons to operation according to technical condition involves increasing the role of measurement operations and control of their parameters and characteristics. This will determine the actual technical condition and make informed decisions about further operation. In general, the effective-ness of control a technical condition of aviation missiles significantly affects the readiness for use of aviation equipment and the combat capabilities of this equipment in performance of the tasks. The exciting control model and methods for selecting parameters of technical condition is universal in relation to the variants of construction of the technical maintenance program a guided air weapons allows to conduct research into these indicators. However, this program does not indicate the plural of variant that should be selected if the undetermined influence of different nature factors to carry out a set of maintenance and repair work for guided air weapons. The possibility of using the principle of correlation, when choosing the program of technical operation a guid-ed air weapons during the transition to operation according to technical condition. With the help of the correlation principle, an approach to the choice of the program of technical operation a guided air weapons can be developed in case of unknown infor-mation about the mechanisms of influence of various internal and external factors on the properties of the guided air weapons, their effect on the technical condition and features of the units of aviation guided missile that are not amenable to instrumental con-trol. To implement the control of guided air weapons with using a principle of correlation need to use the results of practical appli-cations of aviation guided missile, including other types of fire tests, sample tests using the physico-chemical analysis of powder and explosive charges.

While safety in the construction industry has been acknowledged as an important issue, there has yet to be a decrease in the number of disasters. For this reason, to manage and control construction disasters, a study should be conducted on the distribution and use of money allocated to safety management at construction sites. Thus, through an analysis of the current state of safety management cost, a distribution plan was sought, by accident type. In this study, the current state of accidents and safety management cost of four construction sites were analyzed. In the findings of this study, it was found that crash accidents, which have been reported as the accident type most frequently occurring, can be cut by increasing the safety facility cost for the prevention of crashes by more than 50 percent

Taking into account the increasing number of spacecraft the further development of the Russian ground-based control systems (GCS) for Earth remote sensing spacecraft requires new approaches to solving the problems of increasing the efficiency and global control of these spacecraft. The paper considers the possibility of creating a unified ERS GCS (ERS UGCS), including the existing ERS GCS and providing control capabilities for promising, newly created ERS SC. As part of the ERS UGCS, a single control center should be created that provides modeling, planning, analysis and control of future and existing spacecraft constellations and ground-based facilities. Using international experience in managing multi-satellite constellations and implementing our own experience in creating special software for the control centers, for new spacecraft constellations, it is proposed to automate the tasks of a typical regular control cycle, automate periodic maintenance operations of the spacecraft and localize emergency situations. With the aim of automating control processes, the creation of a digital mathematical model of the orbital constellation and ground-based facilities is also proposed for Russian remote sensing constellations. A model that takes into account and describes the spatio-temporal position of the spacecraft constellations, the location of the GCS, ground based data receiving processing and distribution complexes, multifunctional relay stations (MFRS), their technical condition, composition and performance should form the basis for the implementation of end-to-end planning of the main control operations and the targeted use of multi-satellite constellations.

The article analyzes the current state of the fleet of guided air means of destruction (missiles), the problems of repair and extension of the resource. The article substantiates the need for the transition of guided air missile of the "air-to-surface" class to operation according to the technical condition. The shortcomings of the existing inspection system for the technical condition of guided air weapon are shown. For the existing inspection system of technical operation of guided air weapon, one of the areas that will solve the problem of maintaining the combat readiness of aircraft is the transition to the operation of guided air weapon in technical condition. It is shown that the transition of guided air missiles to operation according to the technical condition and modernization of unguided air missiles involves strengthening the role of operations to measure and control their parameters and characteristics in order to determine the actual technical  condition and make informed decisions about their further operation. Peculiarities of appearance of the Type 1 and Type 2 errors during control of a technical condition of aviation armament are presented. A method of increasing the reliability of air-to-surface missile control equipment by conducting control checks in the inter-check interval is proposed. The fundamental difference between the proposed information-redundant model of operation of guided air missiles and the classic model is the introduction into the system of operation a new diagnostic operation - an intermediate control check. Peculiarities of application of the developed method concerning calculation of both quantity of control checks and their periodicity within an inter-check interval are shown.

The aim of the study was to determine the capacity of a selected section of the Sanna river, designated below the lower site of the weir in Zaklików. The capacity calculations included the conditions of flood water discharge, i.e. the reliable flow and the control flow, determined in accordance with the Regulation of the Minister of the Environment on technical conditions that should be ensured for the hydrotechnical structures and their locations. The paper presents the consequences of changes in the regulations regarding the determination of building type, for which reliable flow and control discharges are determined. These modifications in the regulations have an impact on changes in the determination of the probability value for water discharges related to the analysed weir. The calculation of the capacity of the tested section also took into account its technical condition, specifying the variant of calculations for the lack of maintenance works, i.e. for the current state and for the state after maintenance works, consisting in mowing vegetation on slopes and shaping the surface of river bottom, removing pits and shallows. The results of the calculations of capacity of the measured cross-sections showed that the performance of maintenance works will convey the flow of a Q3% reliable flow in the Sanna river, while the Q1% control flow will not fit into the riverbed and will cause inundation of the adjacent areas.

Knowledge of material pseudodielectric functions at MBE growth temperatures is essential for achieving in-situ, real time growth control. This allows us to accurately monitor and control thicknesses of the layers during growth. Undesired effusion cell temperature fluctuations during growth can thus be compensated for in real-time by spectroscopic ellipsometry. The accuracy in determining pseudodielectric functions is increased if one does not require applying a structure model to correct for the presence of an unknown surface layer such as a native oxide. Performing these measurements in an MBE reactor on as-grown material gives us this advantage. Thus, a simple three phase model (vacuum/thin film/substrate) can be used to obtain thin film data without uncertainties arising from a surface oxide layer of unknown composition and temperature dependence.In this study, we obtain the pseudodielectric functions of MBE-grown AlAs from growth temperature (650°C) to room temperature (30°C). The profile of the wavelength-dependent function from the ellipsometry data indicated a rough surface after growth of 0.5 μm of AlAs at a substrate temperature of 600°C, which is typical for MBE-growth of GaAs.
