Abstract
The problem of angular orientation of a moving object is solved using measurements of the strapdown inertial navigation system (SINS) and the satellite navigation system (SNS) under the most general assumptions about the character of the angular motion of the object and probabilistic characteristics of noises in inertial measurements. The soltion is obtained in the form of an extended Kalman filter in which the direction cosines of rotation in an inertial coordinate system are used as estimated orientation parameters and the vector of measurements by the SNS and SINS accelerometers is used as the observation vector. An example illustrating the high stability and convergence rate of the process of estimating the chosen parameters of angular orientation of the moving object is presented.

Abstract
Using the equivalent transparency models, the Fraunhofer diffraction phenomena in the coherent light are studied at an extended object with a constant thickness in the shape of a volumetric asymmetric edge with a bevel and a plane reflecting (gray) inner surface of the object characterized by the module of reflection coefficient and the phase shift in the reflected wave. It has been shown that the far-zone field can be represented in the form of two components: transmitted and reflected, the first of which corresponds to light diffraction at an absolutely absorbing asymmetric edge, while the second describes diffraction phenomena at the volumetric structure in the shape of a biplanar slot illuminated by a plane light wave. Based on the constructive approximation of the integral Fresnel function, an expression has been obtained for the object spectrum, which can be used to investigate the behavior of the far-zone fields. It has been shown that in the case of a large bevel, the main contribution to the field is made by the reflected component. The methods are proposed for determining geometric parameters of the object by measuring the position of the central maximum of the reflected component and its effective width.

Abstract
Studying images of a whole core (a sample of rock extracted from a well) is in demand in modern geophysics. The subject area determines the specifics of core image processing and the form of presentation of the results. A common way to represent well data is by depth-ordered measurement values. Core samples are also ordered by depth, and sample images are a collection of individual photographs or tomographic scans, often without data at some depths. A typical image of one core fragment contains a meter-long section of rock. In practice, it is often necessary to evaluate the characteristics of centimeter intervals. An approach to creating an ensemble of textural features of core images presented as depth-ordered profiles is proposed. The results can be used in conjunction with other geological and geophysical data.

Abstract
Theoretical investigations of the dependence of the optimal thickness of a one-layer antireflection SiO({}_{2}) coating on a silicon photodiode on the characteristics of the light incident to the photodiode. It is shown that the optimal thickness of the one-layer antireflection SiO({}_{2}) coating for different angular distributions of intensity increases the quantum efficiency of the photodiode by up to 1.1 times in comparison with the classical one-layer antireflection coating with a thickness (lambda/4n), which is optimal in the case of the normal incidence of monochromatic light.

Abstract
A method is proposed that allows one to determine the optimal values of the parameters of singular point detectors (mathbf{p}) from the local characteristics of the image ({mu}). The method is based on searching for the extremum of the analytical dependence (delta=P(mathbf{p},{mu})), where (delta) is the detector efficiency criterion defined as the weighted sum of the type I error and type II error. The dependence (P(mathbf{p},{mu})) interpolates the set (delta(mathbf{p}_{i},{mu}_{j})) obtained from a sample from a set of images of the same type. An experiment was performed with 40 radiographs of the lower part of the human spine, which were processed by the Harris–Stephens detector and SUSAN detector. It is found that when choosing the adjustable parameters of the detector using the proposed method, the (delta) criterion turned out to be significantly lower than for the values of these parameters at the boundaries of the recommended intervals.
摘要 本文提出了一种方法，可以从图像的局部特征（{mu}）中确定奇异点检测器参数的最佳值。该方法基于搜索分析依赖关系的极值（(delta=P(mathbf{p},{mu})），其中(delta)是检测器效率标准，定义为I类错误和II类错误的加权和。P(mathbf{p},{/mu}))的依存关系是从一组同类型图像的样本中插值得到的集合(delta(mathbf{p}_{i},{/mu}_{j}))。实验中使用了 40 张人体脊柱下部的射线照片，并通过 Harris-Stephens 检测器和 SUSAN 检测器进行了处理。实验发现，当使用建议的方法选择探测器的可调参数时，(delta)标准明显低于这些参数在建议区间边界的值。

Abstract
Classic opto-acoustic detectors are popular for a number of scientific and applied uses, such as measuring weak fluxes of optical radiation in the IR and THz ranges, quantitative and qualitative analysis of gas mixtures, and studying the absorption spectra of gases and vapors. The review considers the purpose, design and evolution of the basic structural elements of classic opto-acoustic detectors. We analyze the prospects of using single-layer graphene as the most promising material for membranes. The significant increase in sensitivity is due to the exceptionally high elasticity of graphene combined with its high mechanical strength. It has been shown that using a flexible single-layer graphene membrane reduces the acoustic and vibration noise susceptibility of opto-acoustic detectors by more than three orders of magnitude with no protection against vibration. Since the graphene membrane retains high elasticity at helium temperatures, the operating range of the opto-acoustic detector can be expanded from 320 K to helium temperatures, which provides the theoretically maximum threshold sensitivity by reducing noise and opens up the possibility of using opto-acoustic detectors for astrophysical and cosmological problems. We consider capacitive, optical, tunnel and cantilever detectors of microstrains of a flexible membrane. It is shown that achieving the maximum metrological characteristics of an opto-acoustic detector is possible by combining the unique capabilities of two inventions: a single-layer graphene membrane and a tunnel microstrain detector.
摘要 经典光声探测器在许多科学和应用领域都很受欢迎，例如测量红外和太赫兹范围内的微弱光辐射通量、气体混合物的定量和定性分析以及研究气体和蒸汽的吸收光谱。本综述探讨了经典光声探测器的目的、设计和基本结构元素的演变。我们分析了使用单层石墨烯作为膜材料的前景。由于石墨烯具有极高的弹性和机械强度，其灵敏度得以显著提高。研究表明，使用柔性单层石墨烯膜可将光声探测器的声学和振动噪声易感性降低三个数量级以上，且无振动保护。由于石墨烯膜在氦气温度下仍保持高弹性，光声探测器的工作范围可从 320 K 扩展到氦气温度，从而通过降低噪声达到理论上的最大阈值灵敏度，为利用光声探测器解决天体物理和宇宙学问题提供了可能。我们考虑了柔性膜微应变的电容、光学、隧道和悬臂探测器。研究表明，将单层石墨烯膜和隧道微应变探测器这两项发明的独特功能结合起来，可以实现光声探测器的最大计量特性。

Abstract
Machine learning methods are used to analyze the sentiment of texts and study the efficiency of different architectures of neural networks. It is shown that this is relevant in connection with the development of social networks and online recommendation services, where many users express their opinion about goods and services. Neural network structures are predicted and compared based on real data from social networks. This makes it possible to determine the best architecture for sentiment analysis of texts. This work may be useful to developers of social networks for recommendation services and researchers involved in natural language processing. The results can help improve the quality of analysis of user opinions and improve user satisfaction with goods and services. Thus, this study contributes to the development of machine learning and text data analysis.
