Authors: Qin Wanting , Tang Jun , Lu Cong , Lao Songyang 
Published: September 2021

Abstract
The early warning of abnormal behaviour is helpful to explore the potential risk and avoid the occurrence of accidents. Therefore, it is of great significance to excavate abnormal trajectory patterns from a large number of trajectories. From the perspective of unsupervised learning, a two-level trajectory abnormal detection method based on segmentation and clustering based on segmentation and clustering is proposed in this paper. Firstly, the method considers the influence of a time factor in the stages of segmentation, and segments by the constraint of trajectory state. Then, it redefines the distance between the trajectory segments according to the temporal and spatial distance to cluster after segmentation. Finally, abnormal detection is carried out according to clustering results. In the abnormal detection phase, a two-level detection method is adopted. Firstly, the abnormal trajectory segment is found by first-level coarse-grained abnormal detection. Then, the abnormal subtrajectory segment is detected by second-level fine-grained abnormal detection. The real Atlantic Ocean hurricane data is used for the simulation experiments. Compared with the classical TRAOD detection method, proposed method is more consistent with the actual situation.

Published: September 2021

Abstract
Although significant advances have been made in full-annulus simulation of flow in single-spool compressors. However, no work has been devoted to full-annulus simulation of flow in multi-spool compressors. The aim of the paper is to develop techniques for full-annulus simulation of unsteady flows in multi-spool compressor. The techniques for automatic generation of large-scale full-annulus grid of multi-spool compressor, for uniting simulation in LPC(Low Pressure Compressor) and HPC(High Pressure Compressor) in one solver, for processing LPC/HPC interface in multi-spool compressor in parallel environment, for managing vast amounts of flow field data in multi-spool compressor with low space complexity are proposed. Based on an in-house software ASPAC, these techniques are then applied to full-annulus unsteady simulation of flow in a 13-stage multi-spool compressor with 800 million grid cells using 10240 processes. The numerical simulation results are validated through compared with results of empirical model. Meanwhile, it indicates that results of large-scale unsteady simulation are more precise than results of steady simulation.

Authors: Alekseeva Y A , Garmaev D Ts , Khoroshailo T A , Martemyanova A A 
Published: September 2021

Abstract
Chopped semi-finished meat products are portioned minced meat products based on raw meat, which are produced in a colossal assortment. The types of such semi-finished products, depending on the raw materials used, are divided into: naturally chopped semi-finished meat products made exclusively from meat raw materials; chopped semi-finished meat products, which, in addition to raw meat, include bread products, soybean additives, various cereals, vegetables. Almost all chopped semi-finished products are manufactured according to technical conditions that must meet the requirements of the main regulatory documents applicable to all food products established on the territory of the Russian Federation. Namely, manufacturers themselves develop a recipe for the production of semi-finished products, trying to reduce costs, using raw materials of poor quality or replacing meat raw materials with vegetable ones. This leads to a decrease in product quality. Therefore, it is necessary to pay special attention to the composition of semi-finished products and in their production strictly comply with the current regulatory documents.

Authors: Kvartnikov M P , Kvartnikova E G 
Published: September 2021

Abstract
Rabbit breeding, one of the oldest branches of animal husbandry, provides man with a wide range of agricultural products, the main one being dietary meat. Many domestic and foreign scientists pay great attention to the chemical composition of rabbit meat and the factors affecting it. It is known that the protein content in rabbit meat increases with age, but no significant difference in the protein content in rabbit meat of different breeds has been established. The article shows the dependence of the chemical composition of rabbit meat on the ratio of nutrients in the diet with a dry type of feeding. In a scientific and economic experiment on young rabbits of the Soviet chinchilla breed, the influence of the ratio of nutrients in a complete granulated feed on the chemical composition of meat at slaughter at the age of 90 days was established. It was formed on the principle of analogs of the 2nd group of young animals at the age of 45 days, 60 heads in each: group 1 - control, 2 - experiment. The rabbits were fed with full-feed granulated feed (FGF), consisting of the same plant and mineral components: barley, oats, corn, grass flour, sunflower meal, feed chalk, monocalcium phosphate, table salt. The composition of the FGF 1 of the control group contained 1% of the vitamin and mineral premix P 90-2T; the composition of the FGF of the experimental group contained no vitamin and mineral premix. The diets of the control and experimental groups differed in the ratio of protein, fat and fiber. As a result of laboratory studies by the method of full zootechnical analysis, it was found that the chemical composition of rabbit meat from the hip part does not depend on the nutritional value of the diet, and the neck part does, and the protein content is inversely related.

Published: September 2021

Abstract
In Sverdlovsk region Holstenized black-and-white cattle of the Ural type are used for milk production. Animals of this type feature high productivity indices, however, the breeding stock encountered decrease in the productive longevity. The first-calves showed an increase in milk yield per lactation, along with an increase in their live weight up to 624 kg. The difference in milk yield was significant in favor of cows with a live weight of 600-624 kg. in comparison with the groups of cows with a live weight below 575 kg at P≤0.05-P≤0.01. Among the cows of the third lactation the highest milk yield was obtained from the cows with the highest live weight - 625 kg and more - 10122 ± 118.59 kg. All animals feature an excess over the optimal duration of service period by 19-83 days, i.e. by 23.8-103.8%. The average duration of the lactation period for first-calves is 140 ± 4.69 days, for the full-aged cows - 149 ± 3.98 days. The coefficient of reproductive capacity is 0.85 on average. The positive relationship between milk yield per lactation period and the duration of the service period is confirmed. No general pattern for correlation of live weight and duration of service period.

Abstract
In Sverdlovsk region new Ural type of black-and-white breed with a high proportion of Holstein breed blood relationship has been created. Animals of this type feature high productivity rates. The research of the productive qualities of modern black-and-white cattle, depending on its origin and lactation, is relevant and of practical importance. Milk yield increases from the first lactation to the third. The most significant increase was recorded between the first and second lactations, when the increase in milk yield during the second lactation was 934 and 1.165 kg respectively, or 9.86 and 12.26% (P≤0.05 in favor of the second lactation). For the third lactation, the increase was insignificant and unreliable. There were no significant differences between the lines of cows’ origin. In our opinion, it is explained by thorough and uniform selection of the servicing bulls, a high level of inbred animals in the herd (more than 65%) and cross-breeding. The increase of MFF and MFP in the milk of cows during the second lactation and a slight decrease in these parameters in full-age cows after the third lactation was observed. Correlation of quality indicators and milk yield per lactation varied depending on the ordinal number of lactation, but the quality indicators were almost equally independent from the linear origin of cows. So, the correlation between milk yield and MFF in milk per each lactation increased in negative direction, and content of milk protein ranged from low negative (1stlactation) to low positive (3rdlactation).
