    External Determinants of the Development of Small and Medium-Sized Enterprises – Empirical Analysis by Renata Lisowska

    Published 2015-01-01
    “…The implementation of the above-presented goals was based on the following assumptions: (i) the current situation of the surveyed enterprises is determined with the use of quantitative indicators (turnover volume, number of employees, market share, profit levels) (ii) the analysis of external determinants encompasses three components of the environment: the macro-environment, the meso-environment and the micro-environment, (iii) in each analysed area there are separate analyses conducted for micro, small and medium-sized enterprises, enabling greater precision in the identification of external determinants of development for each category of businesses.…”

    DYNAMIC ANALYSIS AND SIMULATION OF FULL ROTARY BUILT-IN STEERING DRILLING TOOLS by ZHANG GuangWei, QIAO Yang, TIAN Fan, GAO SiTu, YIN FuLai

    Published 2020-01-01
    “…The full-rotation built-in steerable drilling tool is one of the important components of the rotary steerable drilling system.It is a new type of dynamic directional downhole closed-loop rotary steerable drilling tool.In order to study the motion condition of the full-rotation built-in rotary steerable drilling tool,based on the principle of space mechanism,The dynamics concentration parameter model of the full-rotation built-in directional drilling tool was established,and the system dynamics analysis was carried out.The correctness of the model was verified by ADAMS simulation.The results show that the basic parameters of velocity and attitude of the eccentric ring and the guide shaft of the key components are theoretically obtained,and the motion characteristics of the attitude mechanism are revealed.The rotational speed,eccentricity and bit motion of the eccentric ring and the guide shaft are studied.The relationship is obtained,and the variation of each parameter in the guiding system with time is obtained.It lays a theoretical foundation for the research of the full-rotation built-in directional drilling tool and the realization of the optimal design of the drilling system.…”

    Analysis of propagation characteristics of UAV communication scenarios based on parabolic equation by Hui HAN, Yulong HAO, Cheng YANG, Jian WANG

    Published 2022-08-01
    “…To improve the analysis accuracy of the propagation characteristics of UAV millimeter-wave communication scenarios, a method based on the parabolic equation was developed to analyze the propagation characteristics of UAV communication scenarios and simulate the propagation characteristics in urban and suburban areas.The results show that the proposed method can effectively express the influence of terrain parameters on the UAV air-ground communication link.Overall, the prediction results are consistent with the ITU-R statistical method in both scenarios.Effective prediction of the propagation characteristics of millimeter-wave UAV application scenarios can be realized with the proposed method, which may support the design, development, and testing of UAV millimeter-wave communication systems.…”
