Methods for Solving Some Problems of Air Traffic Planning and Regulation. Part I: Strategic Planning of 4D Trajectories
摘要
This paper considers the problems of improving the safety and efficiency of air traffic flows. Particular attention is paid to promising methods for detecting and resolving aircraft conflicts. These methods are classified. We study the problem of minimizing the number of potential conflicts with a promising air traffic control technology, the strategic deconfliction of 4D trajectories. We present a mathematical model to consider uncertainty in the strategic deconfliction of 4D trajectories, a corresponding formal statement as a mixed integer programming problem, and some approaches to solve this problem. Estimating the objective function requires calculating the number of potential conflicts between aircraft. Under uncertainty, this estimation involves a large amount of computations. We discuss an alternative approach to airspace capacity estimation based on air traffic complexity depending on the traffic structure and geometry of the airspace.

European Union’s Carbon Border Adjustment Mechanism as a Global Governance Tool
摘要
This paper considers a greenhouse gas (GHG) emissions management system with an interna-tional component and taxation of imported carbon-intensive goods. As an example, we discuss European Union’s Carbon Border Adjustment Mechanism (CBAM). CBAM is expected to be introduced in 2023. It will have global coverage by countries and companies. We overview the available scientific literature on mathematical methods for analysis and assessment of СВАМ for socio-economic development. As noted, carbon border adjustment provides ample oppor-tunities for mathematical analysis, calculations, and modeling. We outline some classes of models to investigate CBAM: DSGE models, Inter-Country Input-Output Tables, game-theoretic models, and others. Their capabilities for conducting economic analysis are described. Special attention is paid to the analysis models of Global Value Chains. We compile the block diagram of the CBAM management system based on the EU regulatory documents. Its main blocks, participants, and connections are studied. We present and analyze the generic formulas for determining GHG emissions in the European Union. As concluded, CBAM introduction will form a new and broad area of studies on fundamental and applied economics, including man-agement of international carbon border trading markets.

Real Data-Based Personalization of an Automatic Glucose Control System
摘要
This paper overviews the application of machine learning and data analysis methods in medicine. The problem of constructing a closed personalized automatic control system for blood glucose level is considered. Such a system focuses on a particular patient and involves glucose level measurements in the interstitial space by a sensor. We describe a modification of the glucose level regulation model for the blood of a patient during the intake of glucose with meals and the supply of exogenous insulin into the bloodstream. Also, we propose an isolating search method for a group of personalized model parameters to be identified individually. As an example, model parameters are identified for a patient with type 1 diabetes based on real data, and the optimal PD control law of exogenous insulin supply is applied in the identified model. The result is compared with the actual glycemic curve after a single administration of insulin to the patient as recommended by a physician. As shown, the optimal PD control law effectively stabilizes blood glucose level to avoid the development of hypoglycemia. The results of this paper can be used to design automatic glucose control systems for humans (insulin pumps).

Assessing the Risks of Circulatory Diseases due to Noise Exposure in Urban Areas
摘要
This paper describes the basic sources of noise exposure as significant negative physical factors for human health in an urban environment. We present the share of the industrial enterprises and vehicles not meeting hygienic standards of noise impacts for 2012–2021. Noise pollution levels are measured for six districts of Krasnoyarsk, and the territories with the highest levels are identified. The spatial distribution of noise levels is shown for Krasnoyarsk in the evening. The equivalent levels of weighted average daily noise exposure in the Tsentralny and Oktyabrsky districts of Krasnoyarsk are determined. Health risks are assessed by calculating the relative risk of circulatory diseases due to noise exposure. As noted, ensuring noise safety largely depends on determining load levels and obtaining characteristics of noise distribution in various functional areas promptly considering the multiplicity, diversity, and complexity of noise exposure sources. The obtained results can be used to study the impact of environmental factors on human health, perform hygienic diagnosis, elaborate and implement exposure reduction measures, and obtain reliable information about different exposures for human health.

Managing the Handling-Comfort Trade-Off in the Full Car Model by Active Suspension Control
摘要
The effectiveness of a car suspension is usually assessed by the ability to provide maximum ride comfort and maintain continuous contact of the wheels with the road (road holding). This paper develops an active suspension control algorithm for the full car model (FCM) to improve its characteristics by active disturbance rejection control (ADRC). The ride comfort and road holding characteristics of the FCM suspension system are compared with those of the passive suspension. We propose an optimization algorithm for managing the comfort–handling trade-off using a single variable. This algorithm is based on forecasting the future values of the car chassis displacement and the roll angle depending on the dynamics of the ADRC controller on a given horizon. The simulation results confirm the effectiveness of the active suspension system with the proposed algorithm in improving the ride comfort and road holding characteristics.
