Improvement of heat transfer efficiency of the spacecraft thermal control subsystem constitutes a relevant problem for today space industry. Two phase thermal control system presents the most suitable solution for this problem. Implementation of reliable thermal control loop elements constitutes one the major prerequisites for reliability of thermal control systems featuring the operating pressure of 4.8 MPa and ammonia as heat fluid. This paper presents the design and test results of manual valve and fill and drain valve to be operated within the spacecraft two phase thermal control subsystem. The paper provides considerations and detailed description of the technical solutions adopted to ensure compliance with the specification requirements such as operating pressure and plug seat leak tightness under the operating pressure and 160 open/close cycles. Valve plug torque selection criteria are described. The employed design and technical solutions as well as qualification test results have proven that the units designed feature outstanding combination of performances such as leak tightness, life cycle with ammonia as heat fluid.

This paper proposes an algorithm for substantiating the type and volume of redundant structural and functional elements of reconnaissance-firing systems, taking into consideration the operational patterns of such systems. Underlying this algorithm is the combination of survivability assessment methods and reliability assessment methods. Such an arrangement aimed to improve the efficiency of the application of these methods and reduce uncertainty in the calculations. The results from calculating an example of the application of a procedure for substantiating the type and volume of redundant structural and functional elements of reconnaissance-firing systems have been analyzed. The analysis of the results shows that the set task is fulfilled, in particular the specified probability of trouble-free functioning of a reconnaissance-firing system, with a combined type of redundancy. Moreover, it implies giving preference to passive redundancy, using active one only to critical elements – individual functional elements of the control subsystem. The advantage of a mixed type of redundancy over a passive redundancy is 28 %. In addition, it has been established that the multiplicity of redundancy, for accepted conditions, should not be lower than 2. A procedure for substantiating the type and volume of redundant structural and functional elements of reconnaissance-firing systems has been devised, taking into consideration the operational patterns of such systems. The specified procedure includes an algorithm, as well as methods for assessing survivability and methods for assessing the reliability of functioning. This procedure was tested for feasibility by considering an example of justifying the type and volume of redundant structural and functional elements of reconnaissance-firing systems that produced an adequate result. The result has been confirmed by the practical application of reconnaissance-firing systems in recent armed conflicts

The concept and content of control are important components of the theory and methodic of physical culture and sports. The consistency in processes and objective corrections of certain actions (processes) are provided by using of control. Actualization of scientific issues of control in the context of reforming the structure and content of higher education is gaining new importance. This is due to the higher dynamism and student-centered character of modern education. An urgent scientific and applied problem of modern physical education in higher education institutions is the substantiation of a systematic approach to training students swimming that will take into account existing experience and modern requirements. The purpose of the study was to substantiate the control subsystem in the training students swimming in higher education institutions during physical education. Material and methods: theoretical analysis and generalization, study of documentary materials, sociological methods of survey (questionnaire), system analysis, historical and logical research methods. Results and discussion. The control subsystem for the most aspects is management by a higher order system due to the close relationship with the control source, placement trends and the objectivity benefits. This subsystem is the basis for the differentiation of parts and at the same time for integration with the establishment of the organic unity of the whole system components. The key requirement for conducting control in the physical education condition in higher education institution is compliance with the specifics of the sport means as a variable component of the education content. Specific features of swimming have an important value for choosing complex of indicators. In the theoretical substantiation of control, there was observed requirements that are specified in the scientific and methodical literature. Among them are: availability of interval scale, reliability, validity, discriminativeness, availability of normative data, adaptability of the test, ease of execution and simplicity, limitation of test tasks, operationalization and verification of these tests / control exercises). It also takes into account a number of additional requirements for simplicity and low resource costs, regardless of the level of tests complexity, clarity and accessibility for teacher and student, conciseness and accuracy of execution instructions, the absence of external stimuli. Conclusion. Control is a fundamental element of conscious systemic human activity. The result of solving the generalized purpose of the system should be understood, accepted and acceptable to all participants of this process. Substantiation of the control subsystem of the training swimming system involves the formulation of a new category of individually-oriented content of control of students of higher education institutions and its variants. These variants must be built taking into account objective factors (the presence of different groups of students on the level of swimming preparedness, individual-motivational orientation of activity and trajectory of goal setting in the system of training swimming during physical education)

This paper presents a short history of Polish formations protecting the governing bodies of the state, starting from the moment Poland regained independence at the end of the twentieth century. The considerations are presented against the rules and principles of the functioning of the state security system, with particular emphasis on the control subsystem. This paper demonstrates the need to research attitudes to safety in the past, in order to develop and apply effective contemporary solutions. The considerations contained in it also concern the existing threats to the management of state organs. They may contribute to further discussions on the purpose and rules of operation of the formation which is supposed to protect the most important people in the state.

In 2013, the STRaND (University of Surrey and Surrey Satellite Technology Ltd) and the PhoneSat (NASA) programs attracted the attention of the aerospace community applying commercial off-the-shelf smartphones in CubeSats. Both programs deployed CubeSats using smartphones based on Google's Android, in which application development is mainly based on Java programming language. Some of these CubeSats had actuators, e.g., STRaND-1 had three reaction wheels mounted in an orthogonal configuration to provide three-axis control, whereas PhoneSat 2.0 beta had magnetorquers to de-tumble the spacecraft. Taking into account a CubeSat that runs Android operating system (based on a smartphone), it is natural to evaluate the attitude and orbit control subsystem (AOCS) based on Java. Elsewhere, we shown State-Dependent Riccati Equation (SDRE) is a feasible non-linear control technique that can be applied in such CubeSats using Java. Moreover, we shown, through simulation using a Monte Carlo perturbation model, SDRE provides better performance than the PID controller, a linear control technique. In this paper, we tackle the next fundamental problem: stability. We evaluate stability from two perspectives: (1) parametric uncertainty of the inertia tensor and (2) a Monte Carlo perturbation model based on a uniform attitude probability distribution. Through the combination of these two perspectives, we grasp the stability properties of SDRE in a broader sense. In order to handle the uncertainty appropriately, we combine SDRE with H∞. The Nanosatellite Constellation for Environmental Data Collection (CONASAT), a CubeSat from the Brazilian National Institute for Space Research (INPE), provided the nominal parameters for the simulations. The initial results of the simulations shown that the SDRE controller is stable to ± 20% uncertainty in the inertia tensor for attitudes uniformly distributed and angular velocity up to 0.15 radians/second.
