Square tubes have been widely used as energy absorption components. To investigate the influences of multi-cell configuration and loading arrangement on crashworthiness square tubes, eight kinds were numerically analysed under axial oblique loads. Validation was performed against experimental data. According to complex proportional assessment method, T5-1 tube is found best performance. Next, a parameter study analyse effect geometric parameters crashworthiness. It that s/b ratio thickness...
Epilepsy is a severe neurological disorder characterized by persistent seizures and, in some patients, associated neurobiological, cognitive, and psychosocial consequences. It influenced various genetic factors, including the Ephrin-B2 (EFNB2) gene. This study utilized bidirectional Mendelian randomization (MR) to explore potential causal relationship between serum levels of EFNB2 epilepsy using data from extensive genome-wide association studies (GWAS). We selected generalized traits,...
This paper introduces a novel control strategy into the insulation space for liquid natural gas carriers. The proposed can improve effects of differential pressure and reduce energy consumption nitrogen. method combines nonlinear feedback technique with closed-loop gain shaping algorithm (CGSA). It is designed system which vital carriers (LNGCs) in marine transportation. error modulated using function. deviation signal replaced signal. Comparison experiments are conducted under different...
Rigid tapping of NC Tapping center is an electromechanical control system which strongly nonlinear, uncertain and difficult to precise modeling. It unavoidable be affected by some nonlinear factors such as friction mechanical resonance. The traditional method could not fundamentally solve the contradiction between rapid stability high stable precision response. As intelligent method, fuzzy actually a kind PID regulator, it exists strong complementary in dynamic static characteristics. This...
The pressure control for a liquid nature gas (LNG) ship is vital the cargo handling system which nonlinear, unstable, and controllable complex accompanied by dynamics of time delay. To improve effect, this article proposed robust controller based on closed‐loop gain shaping algorithm mirror‐mapping approach. In addition, complete mechanism models are established to predict changes temperature, pressure, inventory in tank. heat exchanges evaporation also considered. By collecting data from...
In order to accelerate the development for LNG carrier liquid handling simulator, this paper describes process. Approaches composition of interactive mathematical models system are outlined. The connections between these described. view current situation simulator development, also provides perspective whole model system. As result incorporation into is being developed by model-based design methodology. It expected through that can reduce training time and cost because researchers understand...
Aiming at the problem of low recognition rate and easy affected by environment during process robot target in complex environments, method combining support vector machine (SVM) with D-S evidence theory was proposed. Taking citrus as an example, SVM used to local classification according color geometry feature information respectively, results were transformed probability outputs through Platt model, treated them basic assignment (BPA) reason fuse results, then realized combination...
In the shortest path planning problem, old algorithm usually has many defects, such as robot's cognition being contrary to reality, lack of practical operation feasibility, or limitation problem processing. Nowadays, with deep learning, artificial intelligence algorithms tend be mature; it become a mainstream trend adopt end-to-end learning system instead traditional algorithms. recent years, rise Internet things emerging technology industry and explosive surge network data traffic, drawback...
为有效克服导向矢量大失配误差对自适应波束形成器的影响，该文提出了一种最差性能最优的分解迭代鲁棒自适应波束形成算法。该算法对非凸的幅度响应约束问题进行分解处理，将问题转化为迭代的二阶锥规划问题，从而可对鲁棒响应区的波束宽度和纹波水平进行自由控制，并可得到较高的输出信干噪比。此外，与现有大部分该类鲁棒波束形成方法相比，提出的算法直接对权矢量进行优化，无需使用谱分解算法，避免了阵列结构的限制，可适用于任意阵形。仿真结果验证了算法的正确性和有效性。
The responses of structures under seismic conditions present very high nonlinearity due to both the parameter variations and nonlinearities forces induced by ground motions. On other hand, an adaptive controller (stabilizer) can adjust itself continuously changes in system. Therefore, this paper examines applicability nonlinear so as enable us design economic attractive which successfully withstand earthquake loading. approach desired active control employs model reference (MRAC) technique....
This paper deals with the problems of converting a continuous-time uncertain system to an equivalent discrete-time interval model and constructing robust hybrid control law for sampled-data system.
