In this article a comparative analysis is made to determine the influence of vectors of selected features derived from geometric, optical and dielectric characteristics of eggs on the accuracy of classification, depending on their weight. Suitable for classification are the principal components and latent variables that reduce feature vectors containing shape indices (D, A, V), spectral indices (TVI, GLI), dielectric characteristics (C, k), selected by four methods (CORR, SFCPP, RELIEFF, FSRNCA). By comparative studies it is found that the use of classification methods (DT, DA, SVM) are more effective in predicting weight of hen eggs than in quail eggs. The proposed egg analysis methods take precedence over the known solutions in this field as it takes into account changes in the internal properties of quail and hen eggs when stored.

The oligomer microstructure, reflecting the configuration of the elementary units (cis-1,4-, trans-1,4-, and 1,2-) and their distribution order in the polymer chain, decisively affects the physicochemical and rheological properties of the oligomer. Parameters of microstructure-dependent transitions (glass transition) characterize the oligomer behavior under abnormal low-temperature conditions. We present the results of studying the microstructure of low-molecular rubbers. We determined the content of cis-1,4- and trans-1,4-structural links of poly-divinyl-isoprene-urethane-epoxy oligomer. The structure of polybutadiene HTPB-IV with terminal hydroxyl groups was analyzed using NMR and IR spectroscopy. A comparative analysis of the microstructure of the poly-divinyl-isoprene-urethane-epoxy oligomer and low molecular rubbers with a known content of structural units has been carried out. The obtained results can be used to obtain oligomers with the desired physicochemical and mechanical properties.

To explore the effects of different factors on the rheological properties of cariphalte modified asphalt, based superpave asphalt binder relevant norms, through the use of dynamic shear rheometer Shell 70# asphalt under different temperature, frequency and strain conditions and rheological properties of cariphalte modified asphalt carrying on a systematic study, and comparative analysis of the two anti-fatigue properties of asphalt in the middle and low temperature.The results show that: compared with 70# asphalt, cariphalte modified asphalt has better rutting resistance over a wide temperature range; at lower frequencies and high intensity pavement, cariphalte modified asphalt to better resistance to permanent deformation; better fatigue resistance at low temperatures, and more fatigue damage is not easy to achieve.

The paper presents the results of numerical simulations (CFD) of hydrodynamic thrust slide bearings lubricated with magnetorheological (MR) fluid. The analyses were carried out to evaluate the influence of the rheological properties of the lubricant, as well as the geometry of the bearing's thrust pad surface. Bearing load conditions were considered on the key functional features of the system, i.e. axial force and torque. The paper presents a comparative analysis of various geometries of thrust bearings and points out possible functional features of hydrodynamic thrust bearings lubricated with fluids with controlled rheological properties.

Abstract The article presents a comparative analysis of the properties of dough and cookies based on oleogels structured with various substances. Oleogels based on beeswax and its fractions were used as an alternative to solid fat in cookies. We found out that the use of separate beeswax fractions in oleogels makes it possible to obtain dough with different rheological characteristics. It was revealed that there is no regularity in the change in the rheological properties of cookies from the properties of the dough and oleogels. Analysis of the organoleptic profile of the cookie samples showed high values. This fact indicates the acceptability of using oleogels based on individual wax fractions in the biscuits cookies. The results obtained indicate the potential of using oleogels based on beeswax fractions in cookies as an alternative to solid fats.
