Noise pollution from construction activities affects both workers and nearby residents. This study proposes a new method for localizing noise sources on construction sites. The method uses a radial microphone array and an algorithm based on the highest signal direction intersections. Simulations show this approach can identify noise source locations with relatively decent ...

Methods for the development of fuzzy and linguistic models of technological objects, which are characterized by the fuzzy output parameters and linguistic values of the input and output parameters of the object are proposed. The hydrotreating unit of the catalytic reforming unit was investigated and described. On the basis of experimental and statistical data and fuzzy ...

The article presents the results and methods of studying the rheological properties of fine-grained concrete mixtures with various additives, as well as the regression equation obtained by calculations using the apparatus of mathematical analysis, which shows the significance of the parameters included in the process of compaction of the ICZB. These data are necessary for ...

In this paper, the problem of global practical output tracking is investigated by state feedback for a class of uncertain nonlinear time-delay systems. Under mild conditions on the system nonlinearities involving time delay, we construct a homogeneous state feedback controller with an adjustable scaling gain. By a homogeneous Lyapunov-Krasovskii functional, the scaling gain ...

Despite the potential applicability of the combination between aluminium (anode) and graphite or titanium (cathode) for poultry slaughterhouse wastewater treatment, their technical and economic feasibilities have not been comprehensively captured. In this study, aluminium (anode) and graphite and titanium as cathode electrode materials were investigated and compared in terms ...

The relevance of the study is conditioned by importance of problems of desertification of lands, included in system of providing natural resources for individual states and the whole geographical regions, and also efficiency of using modern methods of remote sensing of terrains for the effective solution of problem questions of ecological monitoring of desertification zones. ...

Carbon-based nanocomposites have attracted significant attention due to their unique properties and potential for use in various technological applications. In this study, experimental investigations were conducted to determine the spectral properties of carbon-containing nanocomposite polymer films based on polystyrene (PS) with fullerene C60 nanoadditives. The results ...

In the present paper, we take case of a complex scalar field on a Riemannian manifold and study differential geometry and cohomological way to construct field theory Lagrangians. The total Lagrangian of the model is proposed as 4-form on Riemannian manifold. To this end, we use inner product of differential (p, q)-forms and Hodge star operators. It is shown that actions, ...
