We report results obtained during the characterization of a commercial front-illuminated progressive scan interline transfer CCD camera. We demonstrate that the unmodified camera operates successfully in temperature and pressure conditions (-40°C, 4 mBar) representative of a high altitude balloon mission. We further demonstrate that the centroid of a well-sampled star can be determined to better than 2% of a pixel, even though the CCD is equipped with a microlens array. This device has been selected for use in a closed-loop star-guiding and tip-tilt correction system in the BIT-STABLE balloon mission.

The article examines the legal and moral and ethical aspects of a misdemeanor that discredits the honor of an employee of the criminal Executive system. The considered reason for dismissal has the main feature associated with the integration of legal and moral norms, which often raises a lot of questions about the attribution of a particular offense to this basis. Using the analysis of normative legal acts, the authors attempt to identify the signs that contribute to the separation of the studied grounds for dismissal from all their diversity. The classification of offenses that discredit the honor of an employee of the criminal Executive system is presented, which allows to systematize and organize the knowledge obtained about the considered grounds for dismissal. The analysis of a misdemeanor that defames the honor of an employee of the penal system from a moral and ethical position gives an understanding, first of all, that it does not have a clear regulation from the point of view of the law, but the consequences of committing such a misdemeanor are clearly legal. The concepts of “honor” and “dignity” are considered as ethical categories and are analyzed as personal qualities that are manifested in an employee of the penal correction system during the period of service. These categories in the behavior of a person or employee are manifested both externally (assessment from the outside) and internally (self-assessment). The article describes the value orientation of an employee of the criminal Executive system to ethical standards in professional activity, which is an integral part of the moral and ethical side of a misdemeanor that discredits the honor of an employee.

The system of route correction of an unmanned aerial vehicle (UAV) is considered. For the route correction the on-board radar complex is used. In conditions of active interference, it is impossible to use radar images for the route correction so it is proposed to use the on-board navigation system with algorithmic correction. An error compensation scheme of the navigation system in the output signal using the algorithm for constructing a predictive model of the system errors is applied. The predictive model is building using the genetic algorithm and the method of group accounting of arguments. The quality comparison of the algorithms for constructing predictive models is carried out using mathematical modeling.

Статья посвящена изучению зарубежного опыта подготовки кадров для пенитенциарных систем. Его анализ и рассмотрение возможности внедрения отдельных элементов направлены на совершенствование системы подготовки сотрудников для уголовно-исполнительной системы России, повышение их профессионального уровня, что в конечном счете будет способствовать достижению главной цели УИС - исправлению осужденных. Авторы особое внимание уделяют изучению специально-профессиональных и личностных качеств, необходимых сотрудникам пенитенциарных учреждений. В статье рассматриваются особенности подготовки сотрудников пенитенциарной системы в Соединенных Штатах Америки. Важнейшей задачей образовательных учреждений и центров по подготовке кадров для пенитенциарной системы США является обеспечение будущих сотрудников знаниями, необходимыми для выполнения профессиональных обязанностей в рамках предстоящей деятельности. Также авторы подчеркивают важность развития при подготовке будущих сотрудников не только профессиональных, но и личностных качеств.The article is devoted to the study of foreign experience in order to improve the training system for the Russian penal correction system. In particular, the training of prison officials in the United States of America is considered as one of the most developed States in the modern world. The improvement of the training process for the Russian penal correction system implies the development of international cooperation with the prison systems of foreign countries. The study of foreign experience of penitentiary education contributes to the improvement of the professional level of the staff of the Penal Correction Service and, ultimately, to the achievement of the main goal - correction of convicts. The authors pay particular attention to the study of specific professional and personal qualities required by potential prison staff. Since there have been significant positive changes in the formation of professional qualities of the future employee of the Russian penal correction system over the past decade, the main focus of the work is on the formation of personal (universal) qualities of the employee of the Federal Penal Correction Service of the Russian Federation, for which the positive experience of the United States is analyzed.

AbstractIn a general scenario, the brain images acquired from magnetic resonance imaging (MRI) may experience tilt, distorting brain MR images. The tilt experienced by the brain MR images may result in misalignment during image registration for medical applications. Manually correcting (or estimating) the tilt on a large scale is time-consuming, expensive, and needs brain anatomy expertise. Thus, there is a need for an automatic way of performing tilt correction in three orthogonal directions (X, Y, Z). The proposed work aims to correct the tilt automatically by measuring the pitch angle, yaw angle, and roll angle in X-axis, Z-axis, and Y-axis, respectively. For correction of the tilt around the Z-axis (pointing to the superior direction), image processing techniques, principal component analysis, and similarity measures are used. Also, for correction of the tilt around the X-axis (pointing to the right direction), morphological operations, and tilt correction around the Y-axis (pointing to the anterior direction), orthogonal regression is used. The proposed approach was applied to adjust the tilt observed in the T1- and T2-weighted MR images. The simulation study with the proposed algorithm yielded an error of 0.40 ± 0.09°, and it outperformed the other existing studies. The tilt angle (in degrees) obtained is ranged from 6.2 ± 3.94, 2.35 ± 2.61, and 5 ± 4.36 in X-, Z-, and Y-directions, respectively, by using the proposed algorithm. The proposed work corrects the tilt more accurately and robustly when compared with existing studies.
