Abstract
This paper investigated the impact of braking intensity of self-driving cars at different initial speeds on straight road sections on drivers’ comfort, with a view to achieving the comfort optimization of adaptive cruise control (ACC). Specifically, the real vehicle test was conducted in an enclosed venue based on the within-subjects design of 3 × 3 × 2, and the data pertaining to electrocardiogram (ECG) and subjective evaluation of 9 subject drivers in 9 sub tests were collected. Besides, the impacts of different motion states on heart rate variability (HRV) parameters were analyzed using the general linear model for repeated measures, and the relationships among drivers’ comfort, decelerations, and standard deviation of NN intervals (SDNN, an index of HRV) were obtained based on subjective and objective analyses. Additionally, a control strategy based on HRV and fuzzy control was formulated to realize the comfort optimization of ACC in case of an abrupt deceleration of the preceding vehicle, the verifications were performed through joint simulation. The results exhibited that the control strategy based on HRV and fuzzy control could shorten the deceleration time in case of an abrupt deceleration of the preceding vehicle, and may improve the comfort in such scenario.

Authors: Wang Hongli , Zeng Qingning , Zhao Xuejun 
Published: September 2021

Abstract
The actual speech signal is always in a complex environment, which affects the accuracy of speech endpoint detection. In order to improve the accuracy of speech endpoint detection under low Signal-To-Noise Ratio(SNR), a speech endpoint detection technology based on fixed differential beamforming and modulation domain is proposed. Firstly, two microphones of the first-order differential microphone arrays(DMAs) are used to collect the target speech and noise, and then a fixed differential beamformer is used to reduce the noise. Then, the phase compensated modulation domain spectral subtraction method is used to further eliminate the residual noise. Finally, the subband spectral entropy algorithm is used to detect the speech signal endpoint. The experimental results show that, compared with the existing methods, the proposed method has a higher accuracy of speech endpoint detection in the low SNR environment of -10∼5dB.

Published: September 2021

Abstract
The problem of aircraft control involves multiple subjects and has always been extremely complicated in mechanics modelling. Virtual flight simulation was put forward in order to reduce the cost of full-scale airplane flying test and wind tunnel experiment. A typical virtual flight simulator includes a computational fluid dynamics (CFD) solver, a structure dynamics (FD) function, and a flight controller. However, existed virtual flight solver usually ignores the universal modelling of dynamics for complex aircraft configuration and the modularization of CFD, FD and flight controller module, which makes it very inconvenient for many in-house virtual flight codes for engineering application and commercial software development. A new framework of virtual flight simulation platform is established with a parallel Reynolds Averaged Navier-Stokes (RANS) solver, a structured moving overlapping grid function, a generic multiple body dynamics (MBD) solver, and a plug-in type flight controller platform. A universal data exchange interface between MBD and flight controller is presented. An X-wing missile flying forward and pitching-up maneuvering validation case is conducted with the current virtual flight simulator, the result is compared with Matlab Simulink solver based on steady aerodynamic database and good agreement is obtained.

Effects of resonance states in barrier region on non-exponential decay of wave-packets scattered by rounded-rectangular potentials
Authors: Takahashi Kin’ya 
Published: September 2021

Abstract
The decay processes of wave-packets scattered by periodically perturbed and unperturbed rounded-rectangular potentials are studied numerically and theoretically, when the widths of the potentials L are very large. For the case of the unperturbed potentials, four different stages successively arise in the decay process of the wave in the potential region: two pre-exponential decays, namely power–law decay of t
−3 and oscillating power–law decay, exponential decay and post-exponential decay, which is also power–law decay of t
−3. The post-exponential decay is usually extremely small in magnitude. The characteristics of the pre-exponential and exponential decays are explained with the properties of resonance states, i.e. the Gamow states, for the unperturbed system. The rate of the exponential decay is determined by the imaginary part of the eigenenergy of the first resonance state. For the two pre-exponential decays, the ending time of the t
−3 decay is a linear function of L and that of the oscillating power-law decay is proportional to L
3. In the limit of L → ∞, the t
−3 decay is observed persistently, namely the decay for the rounded-step potential. For the perturbed potentials, even if the average energy of an initial wave-packet is relatively smaller than the oscillating potential, the noninstanton tunnelling, i.e. the multi-quanta absorption tunnelling, raises the tunnelling wave component up to the oscillating top of the rounded-rectangular potential, and the tunnelling probability rapidly increases with the perturbation strength. The properties of the resonance states are almost the same as those of the Gamow states because of the flatness of the potential top. As a result, the decay process after the tunnelling is almost the same as that for the unperturbed system. It is suggested that the tunnelling amplitude and tunnelling time, namely the amplitude and period of the pre-exponential decay, can be controlled by the perturbation strength and the potential width, respectively.

Abstract
The article presents data on the study of the effect of organomineral feed additives based on sapropel and zeolite in combination with mineral salt while feeding young horses in the Far North of Yakutia. The research was carried out on young horses of the Yan type of the Yakut breed. Three groups of experimental young horses were selected. Clinically healthy animals were approved for scientific experiment. The research program included the study of growth and development for individual periods of cultivation, assessment of nutritional value of diets by groups, the study of the blood morpho-biochemical composition to determine the effect of feed additives on the animal physiology. Experiments have shown that animals consuming organomineral feed additives grew more intensively and surpassed their peers in all periods of rearing. Thus, at 5 months of age horses from II and III experimental groups surpassed others by 0.78% and 0.50%, and upon reaching 6 months of age this indicator was equal to 2.37% and 1.55%. In total, during the experiment the animals from the experimental groups exceeded the test group by 10.92% and 6.21% in terms of live weight. This is most noticeable in the average daily gain in live weight. Therefore, at the age of 4-5 months the experimental groups grew more intensively than the test group by 8.68% and 3.77%; in the 5-6-month age the result was similar (by 13.16% and 8.65%). It means that feeding organomineral additives to young horses contributed to a significant increase in live weight and to the improvement in the blood morpho-biochemical composition.

Abstract
Flour confectionery is considered as one of the most popular food products. They can’t be included in the food ration of people leading a healthy lifestyle due to their chemical structure and nutritional value. The recent trend is to expand a range of flour confectionery products by imparting functional properties to them. The development of muffins with a reduced sugar and fat content is relevant taking into account the worldwide increase in the level of nutritional diseases (cardiovascular and oncological diseases, obesity, anemia, etc.). Improving the technology of confectionery products by introducing persimmon and feijoa into the formulation of processed products will make it possible to deal scientifically with the issue of the lack of confectionery products with the increased nutritional value and reduced calorie content. So it can improve their assortment and ensure widespread consumption in everyday life. The paper presents the research results concerning the development of technology for muffins enriched with iodine and iron. The paper also states the substantiation of the reduction in the prescription amount of sugar and substitution of margarine with a smaller amount of sunflower oil, as well as the introduction of persimmon puree and pieces of feijoa fruit into the recipe. The presented muffin is characterized by a high content of iodine, iron, calcium, magnesium, potassium and dietary fiber, as well as reduced by a third the content of added sugar and fat.

Published: September 2021

Abstract
The research aimed to substantiate rational parameters of the vacuum freeze-dried sour clotted milk biotechnology. It was revealed that the use of novel starters containing cultures that can synthesize exopolysaccharides provided a symbiotic relationship of fermented milk system particles and prevented its disintegration in freeze dry products rehydration. This was confirmed by microscopic analysis of histological preparations prepared from rehydrated samples of freeze-dried sour clotted milk. It was shown that the addition of topinambour powder resulted in production of freeze-dried sour clotted milk with organoleptic parameters not meeting established requirements. Adding freeze-dried pumpkin powder to the sour clotted milk formulation contributes to increased survival of lactic acid bacteria cells during vacuum freeze drying by an order of magnitude in average. It has been shown that the combined use of novel starter cultures and prebiotics results in production of freeze-dried sour clotted milk with required quality parameters.

Published: September 2021

Abstract
During the extraction of a capillary-porous body, such as the nuclei of fruit seeds, the movement of the distributed substance in the solid phase is carried out by means of molecular diffusion. The amount of material flow in a solid per unit surface is determined by Fick’s law using the diffusion coefficient. The molecular diffusion coefficient depends on the structure of the solid, temperature and soluble substances, and does not depend on the hydrodynamic conditions on the surface of solid particles and the design of the apparatus. The article studies the kinetics of extraction of petals of apricot kernels with ethanol-water solvent. When calculating the value of the residual mass content of plant raw materials during the extraction process, an interval calculation method was used. Based on the experimental data of the extraction kinetics, the molecular diffusion coefficient was determined, which significantly increases during 600-700 s of extraction, and then decreases by 2 times after 1800 s. After 3000 s from the beginning of the process, the diffusion coefficient decreases less sharply. A significant increase in the diffusion coefficient at the beginning of the extraction process, including the impregnation stage, is associated with the uneven distribution of the extracted components in the initial sections of the capillaries. In the studies carried out, the nature of the change in the diffusion coefficient over time does not contradict modern concepts of the mechanism of extraction of a porous structure from plant raw materials.

Published: September 2021

Abstract
The possibilities of obtaining special fat products for baking and confectionery products based on two-stage hydrogenation, both on stationary promoted and dispersed catalysts, are investigated. At the same time, at the first stage, non-selective partial hydrogenation was carried out to obtain liquid baking fats characterized by a sufficient amount of solid glycerides, and at the second stage, this partially hydrogenated fat was subjected to final selective hydrogenation to obtain high-solid confectionery fat. In order to enrich the obtained fats with polyunsaturated fatty acids of the group ω-3, it was first proposed to mix these fats with non-fat flaxseed flour to obtain functional fat-flour compositions.

Abstract
The article deals with the problem of optimizing food compositions from plant raw materials according to the ideal protein profile. The mathematical formulation of the issue is carried out and the result is obtained by a computer software developed by the authors for this class of issues. Two options were used as criteria for the rationality of the blend being composed: with all essential amino acids of the proteins of the developed mixture components, and with only those essential amino acids, the score of which is less than one. The formation of the optimal blend was carried out for two criteria: the minimum score and the proportion of total protein based on plant materials. The resulting blends from mixtures of plant cultures have a higher biological value and can be used to enrich the composition of functional and specialized products, as well as in the development of products and diets for personalized nutrition.

Published: September 2021

Abstract
The milk productivity of animals was evaluated and the content of the metal-ligand forms of iron was studied against the background of changes in the total content of manganese in the blood serum of dairy cows using the hybrid technique (HPLC-ICP-MS). For this purpose, groups were formed for comparing animals with low-normal values of manganese (Mn concentration up to the 25th percentile) and high-normal values (Mn concentration above the 75 th percentile) according to the results of a previous study. The Mn content in the blood serum of all animals was within the physiological normal range. Analysis of the data obtained showed that high-normal levels of manganese in the blood were accompanied by a significant decrease in the indicators of milk productivity of cows. The metal-ligand forms of iron have undergone significant changes. Changes in metal ligand homeostasis can be considered early biomarkers for predicting the state of mineral metabolism to increase productivity.
