Based on binocular stereo vision measurement and wireless sensing theory, this paper studies the measurement and analysis methods of athletes' movement displacement parameters. The main purpose is to explore the relationship between sports biomechanical parameters. The analysis reveals the laws of athletes 'movements, and provides theoretical guidance on athletes' attitude recognition and physical training. Based on the principle of binocular stereo vision, a non-contact displacement measurement system was developed. The displacement measurement system uses template matching to extract the image coordinates of the measurement points and restore the spatial coordinates of the measurement points through European 3D reconstruction, which improves the practicality of the measurement system. In the cantilever beam vibration test, the traditional displacement sensor and binocular image displacement measurement system are used to simultaneously measure the cantilever beam displacement. The experimental results show that the integrated displacement measurement system in this paper has higher accuracy and better stability.

Service and repair of operating and servicing organizations are largely equipped with outdated, low-power, highly specialized bench equipment from former specialized enterprises and do not always meet the technical requirements of the manufacturer, especially for conducting quality control programs for the repair of powerful and modern tractors. These circumstances together reduce the reliability of the obtained diagnostic parameters and may lead to the risk of errors in determining the technical readiness of the repaired equipment, in particular, internal combustion engines, transmission units and chassis, hydraulic drive. (Research purpose) The research purpose is in developing a mobile control and diagnostic device for monitoring the power and fuel consumption of the internal combustion engine, as well as the quality of repair of hydrostatic transmission and hydraulic drive units. (Materials and methods) The article presents an analysis of scientific works on improving methods for diagnosing energy indicators of mobile agricultural machinery, as well as conducted extensive research on the use of axial plunger pumps and throttling the flow of liquid injected by them with a constant and variable cross-section throttle for engine braking. (Results and discussion) Authors developed an experimental model of a mobile control and diagnostic device and experimentally tested the methods for determining its parameters and control and diagnostic operations. (Conclusions) The use of the proposed mobile control and diagnostic device will eliminate excessive fuel consumption by tractors when reducing the effective power of their internal combustion engines below the permissible limits, and will also allow the diagnosis of hydrostatic transmission units in the conditions of agricultural and service enterprises and exclude the sending of serviceable units with unused resources for repair.

The use of mobile control action allows the improvement of technical-economical characteristics of the rectification process and allows for operation regimes that can’t be achieved with traditional control approaches. Mobility lies in the ability to choose the movement law of compound source and energy in the spatial region of apparatus. Mobile control over the rectification process can be realized by changing the column feed point. An optimal number of feed trays must be determined with consideration of cost and output performance, and also the quality of the target product. The work aimed to develop a method for calculating optimal control action, including mobile ones, on the rectification process with additional account for the criterion of maximizing quality of target product, and also, comparison of static column profiles that are optimal by different criteria. Mathematical modeling of the rectification column for separation of water-methanol mixture revealed that increasing quality requirements to target products decreases the number of the optimal feed tray. A method was described for process optimization by the normalized criterion that accounts for separation quality and power consumption. The method was used to determine optimal values of traditional (flows of heat into the column's cube and phlegm) and mobile (feed tray number) control actions that provide the best technical-economical parameters of the rectification column. A proof is presented for the existence and uniqueness of solutions for this optimization problem and the effectiveness of using mobile actions for different requirements to target. The optimal temperature profile of the culms was studied and their characteristic features that correspond to different specific and normalized optimization criteria were found

The search for optimal control algorithms for spacecrafts is one of the key areas in rocket and space technology. Taking into account certain restrictions and requirements in a specific space mission, the selection of certain executive devices of the spacecraft is carried out and the corresponding control law is synthesized. One of such space missions is the providing of angular motion stabilization of a utilized spacecraft with aeromagnetic deorbiting system. The stabilization of spacecraft angular motion is needed for the orientation of aerodynamic element perpendicular to the vector of atmosphere dynamic flux with the aim of increasing of aerodynamic braking force. In this mission, the main optimization criterion is the minimization of the on-board electrical energy consumption which is needed for the control of angular motion. The original construction of the aeromagnetic deorbiting system consists of aerodynamic flat sails element and executive control devices with permanent magnets. However, not all spacecraft can be equipped with additional executive control devices with permanent magnets. That’s why with the aim of expansion of aeromagnetic deorbiting system application, using extra source of electromagnetic control executive devices is proposed in this research.The purpose of the article is the search of the control law which provides minimal consumption of electrical on-board energy by electromagnetic control executive devices during long-term deorbiting mission. For satisfying this criterion of optimization using of mobile control methods to orientate the spacecraft with aeromagnetic deorbiting system are proposed in this investigation. Computer modeling of orbital motion of spacecraft with aeromagnetic deorbiting system show the efficiency of using proposed mobile methods for angular motion control which realized by electromagnetic devices – magnetorquers. It has been showed that because of using mobile control method consumption of on-board electrical energy significantly less than with classical approach. The advantages and disadvantages have been determined.

Subject. A method for optimizing the distillation process using continuous mobile control actions in the feed flow redistribution between the apparatus’ contact devices. Aim. The method development for computation of optimal control actions on the process of multicomponent distillation, including continuous mobile actions, that provide optimal operating modes for columns according to criteria for productivity maximization and energy costs minimization. Results. The static simulation allowed computing the concentration profiles of the column for the separation of the methyl tert-butyl ether synthesis products (MTBE) and it was proved that the feed flow redistribution between two contact devices can significantly affect the apparatus’ static characteristics, meanwhile the quality of the target product is extremely dependent on the redistribution coefficient. The choice of the feed tray is justified considering the criterial losses on the contact devices of the column. The problem of the multicomponent distillation process optimizing for a normalized criterion, which simultaneously includes the process productivity and the energy consumption for its conduct, is solved. The selected criterion extremely depends on the magnitude of the continuous control action, that determines the existence and uniqueness of the optimization problem solution. Conclusions. It is proved that the continuous mobile actions allow providing many modes of operation of the column, unattainable in the class of traditional and discrete, and to improve the technical and economic performance of the process compared with cases of full feed supply to any of the trays.

Improving the control performance of objects with distributed parameters, which include the distillation process, is achievable by using mobile actions. It is known that moving along the column height of the feed point or redistributing a given flow between two contact devices of the apparatus makes it possible to achieve techno-economic indicators of stationary modes unattainable by traditional control. At the same time, transient responses in the column when using mobile actions remained unexplored. To solve this problem, a mathematical model of the dynamics of the distillation process has been developed, taking into account the mobile control actions, and the features of the dynamic modes of operation of the column when using them have been investigated. The model provides for the possibility of implementing disturbances and control actions of various shapes and intensities through several channels simultaneously or at certain points in time. It is established that a new stationary mode is achieved by regulating the pressure at the top of the column, the levels in the tanks to collect the bottom fractions and distillate. The use of PID controllers with actions on the refrigerant flow rate into the condenser and separation products is proposed. The dynamic process model is supplemented by a description of these automatic control loops. Using the developed model, computational experiments are carried out on the example of a column for the separation of a methanol-water mixture. It is proved that transient responses when using mobile control actions on the distillation process are characterized by acceptable quality indicators. The research results are applicable in the construction of systems for automatic mobile control of distillation processes, adaptive, optimal control systems using predictive models.

The article confirms the conclusion about the urgency of the problem of increasing the accuracy of simulation of the processes of servicing mobile testing and diagnostic complexes, which is used in controlling the technical condition of the equipment of radio electronic systems of means of marine transport. The disadvantages of existing measurement control models are that only the influence of the completeness and depth of control on the reliability of the control is taken into account and the quality of maintenance of the most control means that are used in this case is not taken into account. Therefore, an estimation of the readiness coefficient of mobile test and diagnostic complexes for both existing and prospective samples is proposed to be implemented by mathematical modeling of the processes of measuring control of radio-electronic systems with the help of mobile control and diagnostic complexes, which are used at the control of this equipment . The developed simulation model of the influence of the accuracy of the estimation of the availability of mobile control and diagnostic complexes on the reliability of the control of the equipment of radio electronic systems of means of marine transport, which allows to determine the interconnection between the quality of service of the system and the reliability of the determination of the actual technical state of the equipment, is monitored. The article presents an imitation model of the reliability of control of radio electronic systems of means of marine transport. Calculations have shown that increasing the coefficient of homogeneity of mobile control-diagnostic complexes by (1,5–2) % allows to increase the reliability of control of equipment of radio electronic systems of sea transport up to 10 %.

The current problem in the process of training miners is to ensure the mobility and the ability to perform exercises not only on simulators, but also in real conditions of the mine. Therefore, the software and hardware platform of the training complex should include not only imitators of isolating breathing apparatus for developing proper breathing skills in self-rescuers, but also mobile control systems. This will allow carrying out the learning process in conditions similar to real, will increase usability by eliminating wired data transfer interfaces. In addition, the mobile control system of the simulator monitors the trainee's state indicators in real time in an understandable form for him on a wristband or watch. For the implementation of software and hardware of such system, appropriate structural and functional models were developed, including patterns of interaction between components, data transfer and processing processes. On their basis, a software and hardware implementation of a mobile simulator control system is carried out. The results can be applied in the development of mobile controls in various software and hardware platforms.

As mobile devices became more affordable, people at all job levels started bringing their personal devices to work. All of a sudden, people saw workers whose jobs involved manual labor pull out their mobiles and tap away. There was an assumption that they were often cyberslacking—wasting work time on non-work tasks. This chapter introduces a group of janitors who were banned from using their personal devices at work. But their supervisors were stuck in an awkward place: sandwiched between needing to communicate face-to-face with their subordinates and being expected to be constantly reachable through multiple devices because that’s how their own managers communicated. The ban reinforced existing power structures; there were issues of trust, language barriers, computer literacy, and inconsistent enforcement of rules. This ban actually harmed productivity, and the findings suggest that these manual workers can use mobile devices productively: they still need access to on-the-job information.

Machine Type Communications (MTC) are emerging as a revolutionary paradigm in the present and future mobile generations, expected to experience an explosive growth in the next few years. This new concept will exhaust the control plan of mobile infrastructures by triggering excessive and heavy signaling procedures. In addition, MTC devices are vulnerable and can be exploited to launch distributed DOS (DDoS) attacks against the sensitive signaling plan, these security flaws are very tricky to be noticed. In this paper, we examine a new signaling DDoS attack that exploits the low duty-cycle of machine-to-machine (M2M) communications to saturate the mobile control plan capacity. To defend against this type of attacks, we propose a real-time cost-effective detection approach relying on the recurrence property of the Markov chain characterizing the M2M traffic evolution over time. Extensive simulation results show that the designed signaling DDoS attack will generate a considerable overwhelming signaling traffic leading to a severe availability issue in the critical mobile infrastructure. Besides, our proposed detection mechanism identifies successfully this signaling attack with a detection accuracy around 91% and a fast detection time capped at 380 seconds.

To conduct the lift support task, the robot must firstly know the intention of users. In this paper, we focus on the research on the recognition of the directional intent of users. Therefore, a new directional identification method based on the head posture of users was proposed. A fuzzy reasoning method is proposed to predict the users’ behavior intent based on the principle of Kalman Filter and spatial data fusion. The wheelchair robot also can realize Omni-directional mobile control of the intelligent wheelchair. Prototype were conducted using the proposed developed robot and the results demonstrate its feasibility and efficacy.

The EMG signals can be produced from the human muscle activity. This paper explains the control system of the robot mobile which uses the EMG signal from three muscles contraction such as the jaw muscles, the right arm muscles, and the left arm muscles. The peak values of the EMG signal was used as the input to the ANN system using the Backpropagation algorithm, and it produces the output which has nine target conditions; the forward, then turn right and then turn left where each of them has the variations such as the slow, the medium and the fast. The ANN has been trained with 270 of the training data, and it has been tested with 135 of the testing data from 15 respondents who performed muscle contraction activities. Based on the test result, there are only two unrecognizable data with the rate of the system accuracy is 98.52%. The movements of the robot mobile can be controlled based on the recognized movement patterns with the specified target conditions.

The mobile control of the wheeled mobile robot is affected by local disturbance error, which leads to low control precision. A mobile control model of wheeled mobile robot based on RTK-GPS (real-time kinematic GPS) is proposed. The mobile control system of wheeled mobile robot is designed with embedded ARM technology as the core processor of controller. Firstly, the mobile control algorithm of wheeled mobile robot is designed. The attitude determination parameter of wheeled mobile robot is taken as the control constraint parameter, and the attitude determination control of the wheeled mobile robot and the path map traversal of attitude parameter output are processed. According to the coordinate position of the locus map, the robot's moving location is carried out, and the trajectory following adjustment is realized by RTK-GPS technology, and the control law is optimized. Then the hardware of the control system is developed under the embedded ARM technology integrated information processing environment. The robot attitude adjusting system, the central integrated control module and the man-machine interaction module are designed and described in detail. The system test results show that the proposed method has better output performance, lower attitude determination error and better control convergence of wheeled mobile robot.

After the Fukushima nuclear accident, means to mitigate the severe situation have been proposed in many countries. One of those means is the mobile control room in which operators can monitor and control the damaged facilities from remote locations. The mobile control room is different from usual main control rooms of nuclear power plants in aspects of the quantity of transmitted information and the size of room space. A new type of operator interface for the mobile control room is required as operator tasks are reduced but more critical. A prototype of operator interface which aims to provide direct perception and manipulation function is shown in this presentation. The operator interface runs on 3D environment and is being developed on a touch device-SUR40. Currently, navigation from a site to a unit, zooming in/out for monitoring the overall status of facilities and diagnosing faulty components and controlling active components can be carried out through this prototype.
