Aircraft Ground Taxiing Deduction and Conflict Early Warning Method Based on Control Command Information

Aircraft taxiing conflict is a threat to the safety of airport operations, mainly owing to human error in control command information. To solve this problem, an aircraft taxiing deduction and conflict early warning method based on control order information is proposed. Our method does not require additional equipment or operating costs, and is completely based on historical data and control information. To detect conflicts with other taxiing aircraft when an aircraft taxis according to commands, it can infer the future route and calculate the probability of conflict with other taxiing aircraft. Validation of the method was conducted using real-world airport taxi data. The results show that the method can effectively predict the aircraft taxiing process and provide an early warning of possible conflicts. Decision support systems for airport operations can benefit from this method.

Design of a decentralized Internet-based control system for industrial robot robotic arms

Abstract To meet the needs of small and medium-sized processing plants by establishing a software and hardware platform for a robotic arm control system with a hierarchical structure and designing a robot robotic arm motion control system that is adaptable to multiple environments and cost-effective. In this paper, the industrial robot robotic arm motion control system is designed based on the consistent fusion tracking algorithm under the decentralized Internet. While using the VisualC++ development environment for writing human-machine interface programs using the MFC framework, the device controls the robotic arm body to complete predetermined movements or operational tasks based on command information, sensing information, and the robot controller. The AMS1086CD-3.3 low-voltage differential linear regulator chip used in this design effectively implements the circuit design from 4.8V to 3.4V and successfully meets the 3.4V voltage supply required by the controller. The industrial robot robotic arm control system adopts an adaptive backstepping algorithm controller, and the error of the tracking system at 0 seconds in the simulation results is always kept within the range of [-1~1] that meets the requirements, which effectively reduces the control error of the robotic arm position. Therefore, the robotic arm control studied in this paper is composed of a complete control system in hardware and software, and the designed adaptive backstepping algorithm controller achieves the demand for good control performance of the robotic arm proper.

Study on Forecasting Break-Up Date of River Ice in Heilongjiang Province Based on LSTM and CEEMDAN

In spring, rivers at middle and high latitudes in the Northern Hemisphere are prone to ice jams, which threaten the safety of hydraulic structures in rivers. Heilongjiang Province is located on the highest latitude in China, starting at 43°26′ N and reaching 53°33′ N. Rivers in Heilongjiang Province freeze in winter and break up in spring. Forecasting the break-up date of river ice accurately can provide an important reference for the command, dispatch, and decision-making of ice flood preventing and shipping. Based on the observed break-up date series of river ice from seven representative hydrological stations in Heilongjiang Province, the complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) was used to decompose the observed break-up date series of river ice into several subsequences, and the long-short term memory neural network (LSTM) was used to forecast the subsequences decomposed by CEEDMAN. Then, the forecast results of each subsequence were summed to obtain the forecasting value for the break-up date of river ice proceeded by CEEMDAN-LSTM. Compared with the LSTM, the forecast accuracy of CEEMDAN-LSTM for the break-up date of river ice had been significantly improved, with the mean absolute error reduced from 0.80–6.40 to 0.75–3.40, the qualification rate increased from 60–100% to 80–100%, the root-mean-square difference reduced from 1.37–5.97 to 0.95–1.69, the correlation coefficient increased from 0.51–0.97 to 0.97–0.98, and the Taylor skill score increased from 0.87–0.99 to 0.99. CEEMDAN-LSTM performed well in forecasting the break-up date of river ice in the Heilongjiang Province, which can provide important information for command, dispatch, and decision-making of ice flood control.

Cybersecurity risk assessment of VDR

AbstractThe voyage data recorder (VDR) is a data recording system that aims to provide all navigational, positional, communicational, sensor, control and command information for data-driven investigation of accidents onboard ships. Due to the increasing dependence on interconnected networks, cybersecurity threats are one of the most severe issues and critical problems when it comes to safeguarding sensitive information and assets. Cybersecurity issues are extremely important for the VDR, considering that modern VDRs may have internet connections for data transfer, network links to the ship's critical systems and the capacity to record potentially sensitive data. Thus, this research adopted failure modes and effects analysis (FMEA) to perform a cybersecurity risk assessment of a VDR in order to identify cyber vulnerabilities and specific cyberattacks that might be launched against the VDR. The findings of the study indicate certain cyberattacks (false information, command injection, viruses) as well as specific VDR components (data acquisition unit (DAU), remote access, playback software) that required special attention. Accordingly, preventative and control measures to improve VDR cybersecurity have been discussed in detail. This research makes a contribution significantly to the improvement of ship safety management systems, particularly in terms of cybersecurity.

DEVELOPMENT OF THE FINANCIAL MARKET: DESTABILIZING PROCESSES, THEIR ASSESSMENT, AND GLOBAL IMPACT

The subject of the study is the process of destabilization of the financial market of Ukraine in modern conditions. Methodology. The research used general scientific methods, in particular: theoretical generalization, methods of positive and normative analysis, and statistical analysis. The goal is to assess the processes of destabilization of the financial market of Ukraine in modern conditions. Research conclusion. For the formation of command information oriented to the production of effects in current conditions, it is necessary to provide in mathematical logic: 1) a comprehensive study of static (permanent) characteristics of the financial market as a hierarchically ordered combinatorial system; 2) research of existing trends in the development of the financial market of Ukraine according to the elements of its combinatorial structure; 3) specification of critical problems and obstacles to the development of the financial market (according to the elements of its combinatorial structure), which may negatively affect the performance of the financial market. The financial market of Ukraine is a complex structure characterized by constant structural changes. Currently, the financial market of Ukraine is characterized by somewhat contradictory trends of its development, taking place against the background of increasing stochasticity of its environment. Naturally, it is necessary to create opportunities to estimate and forecast the flows of financial resources and changes in the financial market associated with these flows by building a complex of models that provide 1) forecasting possible behavioral reactions of the integrated performance of the financial market on the basis of existing trends in changes in the value characteristics of assets under the influence of various influencing factors in stochastic models; 2) step-by-step descriptive-numerical representation of data in dynamic programming models to identify possible changes in the structure of the financial market. It is this content of the models that is important because it not only determines the possible directions of strengthening, vulnerability and destabilization of the financial market, such a model basis increases the scientific validity of the developed strategic priorities aimed at preventing destabilization processes on the efficiency of the financial market in the future.

Optimized System Identification of Humanoid Robots with Physical Consistency Constraints and Floating-based Exciting Motions

Generally, robots are initially designed via computer-aided software to obtain their parameters. However, the given parameters are not entirely true due to their unmodeled parts; therefore, system identification is needed, and physical conditions are crucial to guarantee feasible solutions. This study uses a quadratic programming regression model accompanied by physical consistency constraints and designs specific exciting motions for humanoid robots. The proposed constraints are designed based on the geometric approximation of link objects, the physically reasonable mass and inertia and the total mass of the robot being correct. The proposed exciting motions include the general walking motion and the single-leg support motion, which enable a more flexible and stable way to cause excitation in the floating-base system. The identified parameters are evaluated on the humanoid robot NINO. Furthermore, the error between the feedback information of the zero moment point and the command information of the center of mass are used for evaluating the identified dynamic parameters. According to the experiments with the proposed exciting motions, the identified parameters are found to be obviously better than the original computer-aided design parameters, especially in the [Formula: see text] direction.

Evaluating the moderating effect of in-vehicle warning information on mental workload and collision avoidance performance

Purpose The presentation of in-vehicle warnings information at risky driving scenarios is aimed to improve the collision avoidance ability of drivers. Existing studies have found that driver’s collision avoidance performance is affected by both warning information and driver’s workload. However, whether moderation and mediation effects exist among warning information, driver’s cognition, behavior and risky avoidance performance is unclear. Design/methodology/approach This purpose of this study is to examine whether the warning information type modifies the relationship between the forward collision risk and collision avoidance behavior. A driving simulator experiment was conducted with waring and command information. Findings Results of 30 participants indicated that command information improves collision avoidance behavior more than notification warning under the forward collision risky driving scenario. The primary reason for this is that collision avoidance behavior can be negatively affected by the forward collision risk. At the same time, command information can weaken this negative effect. Moreover, improved collision avoidance behavior can be achieved through increasing drivers’ mental workload. Practical implications The proposed model provides a comprehensive understanding of the factors influencing collision avoidance behavior, thus contributing to improved in-vehicle information system design. Originality/value The significant moderation effects evoke the fact that information types and mental workloads are critical in improving drivers’ collision avoidance ability. Through further calibration with larger sample size, the proposed structural model can be used to predict the effect of in-vehicle warnings in different risky driving scenarios.

Interplay of tactile and motor information in constructing spatial self-perception

During active movement, there is normally a tight relation between motor command and sensory representation about the resulting spatial displacement of the body. Indeed, some theories of space perception emphasize the topographic layout of sensory receptor surfaces, while others emphasize implicit spatial information provided by the intensity of motor command signals. To identify which has the primary role in spatial perception, we developed experiments based on everyday self-touch, in which the right hand strokes the left arm. We used a robot-mediated form of self-touch to decouple the spatial extent of active or passive right hand movements from their tactile consequences. Participants made active movements of the right hand between unpredictable, haptically defined start and stop positions, or the hand was passively moved between the same positions. These movements caused a stroking tactile motion by a brush along the left forearm, with minimal delay, but with an unpredictable spatial gain factor. Participants judged the spatial extent of either the right hand's movement, or of the resulting tactile stimulation to their left forearm. Across five experiments, we found that movement extent strongly interfered with tactile extent perception, and vice versa. Crucially, interference in both directions was stronger during active than passive movements. Thus, voluntary motor commands produced stronger integration of multiple sensorimotor signals underpinning the perception of personal space. Our results prompt a reappraisal of classical theories that reduce space perception to motor command information.

FERRAMENTA DE APOIO AOS COMANDANTES DAS OPERAÇÕES DE SOCORRO EM INTERVENÇÕES ESTRUTURAIS DAS EQUIPAS DE BOMBEIROS

In a scenario of structural intervention situation, the On-Scene Commanders (COS) only have at their disposal the data provided by the one who gave the alert, which are insufficient to provide a secure and informed decision-making. Through a quantitative, descriptive, observational, and cross-sectional research, using a questionnaire applied to operational staff who perform the COS function, results a survey of the COS information needs. According to the results, it is concluded that the purpose of knowing the risks and outlining a more effective, faster and safer combat strategy for operational personnel involved, could be compromised by the limited information available. A proposal for a new support tool for COS function - the Initial Intervention Plan (PII) - was developed, which is a document of quick and intuitive consultation, supplying the needs of information for COS.

Dual event‐triggered control for linear systems with consecutive packet losses

AbstractThis article investigates an event‐triggered control for linear continuous‐time systems by tolerating consecutive packet losses. Two event‐triggers are, respectively, employed in the sensor‐to‐controller and controller‐to‐actuator channels in order to reduce the data transmission pressures. A simple discrete‐time state feedback control law is proposed and the control command is only updated when the actuator successfully receives the command information. By the proposed method, the event‐triggers are proved to be maintained or violated consecutively. The appropriate data sampling period and the maximal allowable packet loss numbers can be quantitatively determined. In addition, it is also proved that the event‐trigger in controller‐to‐actuator may not be violated immediately with the event‐trigger in sensor‐to‐actuator. The uniform ultimate bound of the closed‐loop system can be achieved. Finally, numerical examples are provided to demonstrate the effectiveness of the proposed method.

시스템의 기술적 특성 및 개인특성이 상황인식과 의사결정에 미치는 영향 : 육군전술지휘정보시스템(ATCIS) 활용을 중심으로

This study aims to identify the effects of the technological and individual characteristics of army tactical command information system (ATCIS) on situation awareness and decision making, under the concept of network-centric modern warfare. On the basis of adaptive structuration theory and situation awareness theory, we consider the technological characteristics of the system as real time, convergence, and information visualization effect. System experience and IT capability are used as the variables for individual characteristics. We hypothesize that these variables affect users’situation awareness which leads to their decision making. A field survey is administered to the Republic of Korea (ROK) Army officers who have experienced using the system for more than six months.BR Survey results show that excluding real time, convergence and information visualization effect influence users’situation awareness. Users’ system experience and IT capability also increase situation awareness. The higher the degree of users’ situation awareness, the better their decision making. Theoretically, this study implies thatthe effects of the technological and individual characteristics of ATCIS on situation awareness must be investigated. Practically, our study guides and suggests development plans for the ATCIS to the ROK Army.
