ABSTRACT Obesity, which is often caused by adipocyte metabolism dysfunction, rapidly becoming a serious global health issue. Studies in the literature have shown that camellia oil (Camellia oleifera Abel) exerted potential lipid regulation and other multiple biological activities. Here, we aimed to investigate effects of on obese mice induced high-fat diet explore gut microbiota alterations after intervention. The results showed oral administration dramatically attenuated fat deposits, serum...
A new low-thrust trajectory design method is proposed that based on the finite Fourier series with pseudoequinoctial elements rather than more common cylindrical coordinate components. The bijection relation between and control variables ensured by introducing an additional equality constraint derived from angular momentum conservation. guidance law on-line are obtained applying inverse dynamics framework of simulation technology, respectively. has advantages both perturbation analysis...
The inverse simulation is a technique used to calculate the control action based on expected trajectory or experimental data and has been applied successfully in aviation field. A novel first introduced fields of rendezvous docking. least square estimation under hyper-ellipsoidal restriction presented solve problems. structure this paper model predictive scheme. derived by Clohessy–Wiltshire dynamics equations, accurate one obtained two-body equations. When designed trajectories...
The exploration of the Moon has always been a hot topic. determination Moon-to-Earth transfer opportunity and design precise trajectory play important roles in manned missions. It is still difficult problem to determine return for accurate atmospheric re-entry landing, through which actual can be easily obtained later. This paper proposes an efficient integrated method window searching optimization considering constraints Earth landing. First, analytical geometry-based proposed state point...
Based on the characteristics of manually controlled rendezvous and docking, this paper proposes a novel discrete inverse-simulation method for investigating handling qualities. The proposed was verified by teleoperation console experiments. steady-state error stability were analyzed using Z-domain criteria theoretical simulation. Furthermore, to reduce high-frequency oscillations caused observed errors, modified combining it with adaptive predicted-threshold filtering. simulation results...
Modeling and Simulation is considered as an important method for astronautics. Confronting with considerable amount of analysis simulation requirements, a generic software framework proposed to support the aerospace system reduce costs, compress development periods, raise efficiency. AstroSim, easily used simulation, described have object-oriented combined resources layer tools layer. After overview progress, design conceptions realization are introduced in this paper. The architecture...
The development of the rocket design process depends heavily on effective and accurate modeling method. This paper elaborates procedure to establish variable structured simulation package with declarative modeling language Modelica. package includes library with basic rocket components products subsystems segments. Some components like body and measurement take full advantages Modelica object-oriented characters, while others control system aerodynamics are assembled basis...
Coverage analysis is a foundation computation of space missions, which calculates figures merits and visible periods the spacecraft. Conventional algorithms are computationally efficient but lack universality because they deal specifically with particular conditions special orbits specific objects. In this study, coverage tool that rectifies state affairs was developed using plugin. The decouples calculation from orbit propagation thereby facilitates efficiency, universality, flexibility....
During the launch of a rocket or missile, certain segments must separate from main body, and reliability this separation can affect final success mission.Most reports on analysis specific structures employ finite element software programs; moreover, although most studies focus simple dynamics segments, few consider in distribution analysis.Thus, generalized variable topological dynamics-based aerospace method is proposed paper.With exception basic constraints imposed by external forces,...
