Meso-Scale Tearing Mechanism Analysis of Flexible Fabric Composite for Stratospheric Airship via Experiment and Numerical Simulation
Journal of Shanghai Jiaotong University (Science) - Tập 27 - Trang 873-884 - 2022
Stratospheric airships are controllable lighter-than-air aircraft and have great potential application in surveillance and communication. The envelopes, one of the main structures of a stratospheric airship, are generally made of flexible fabric composites to be lightweight, high strength, capable of containing lifting gas, and resistant to the harsh stratospheric environment. The composites, howe...... hiện toàn bộ
Hybrid process of fabricating high-quality micro wine-glass fused silica resonators
Journal of Shanghai Jiaotong University (Science) - Tập 22 - Trang 274-279 - 2017
A new hybrid method, which combines improved glass-blown technology with wet etching, is reported to fabricate micro wine-glass resonators with high-quality fused silica. The optimum placement is compared to achieve the resonators with good shell shape. The typical shell diameter is about 4mm and its thickness covers from dozens to hundreds of micrometers. The etching rates in corrosion solutions ...... hiện toàn bộ
Dynamic Modeling and Performance Evaluation of a Novel Humanoid Ankle Joint
Journal of Shanghai Jiaotong University (Science) - Tập 27 - Trang 570-578 - 2022
Aimed at the problems of design difficulty and weak kinematic performance caused by spherical joint, a novel PRC+PRCR+RR humanoid ankle joint based on the partially decoupled spherical parallel mechanism is proposed. According to screw theory, the degree of freedom and decoupling characteristics of this mechanism are analyzed. Based on Klein formula and virtual work principle, the kinematic expres...... hiện toàn bộ
Lattice reduction aided MMSE Tomlinson-Harashima precoding based on VBLAST algorithm for MIMO systems
Journal of Shanghai Jiaotong University (Science) - Tập 13 - Trang 12-15 - 2008
A lattice reduction aided (LRA) minimum mean square error (MMSE) Tomlinson-Harashima precoding (THP) was proposed based on vertical Bell Labs layered space time (VBLAST) algorithm for multiple input multiple output (MIMO) systems. The extended channel was used to provide optimal tradeoff between residual interference and noise amplification. The processing based on lattice reduction method helps a...... hiện toàn bộ
Spectrum-Sensing Method for Arc Fault Detection in Direct Current System with Lithium Batteries
Journal of Shanghai Jiaotong University (Science) - Tập 28 - Trang 630-637 - 2022
We mainly study the detection of arc faults in the direct current (DC) system of lithium battery energy storage power station. Lithium battery DC systems are widely used, but traditional DC protection devices are unable to achieve adequate protection of equipment and circuits. We build an experimental platform based on an energy storage power station with lithium batteries. Then, the data collecti...... hiện toàn bộ
Collapse Patterns and Their Discrimination of Reinforced Concrete Shear Wall Under Combined Stresses of Compression and Shear due to Strong Earthquake
Journal of Shanghai Jiaotong University (Science) - Tập 25 - Trang 495-508 - 2020
The collapse patterns of reinforced concrete (RC) shear walls under seismic load are proposed. The crack distribution and propagation of shear walls are specifically based on the failure criterions of Mohr-Coulomb with tension cutoff. Three zones and five different corresponding failure modes of RC shear walls are determined according to the transfer path of shear stress in shear wall. These failu...... hiện toàn bộ
Recursive least squares algorithm for a nonlinear additive system with time delay
Journal of Shanghai Jiaotong University (Science) - Tập 21 - Trang 159-163 - 2016
This paper proposes a recursive least squares algorithm for a nonlinear additive system with time delay. By the Weierstrass approximation theorem and the key term separation principle, the model can be simplified as an identification model. Based on the identification model, a recursive least squares identification algorithm is used to estimate all the unknown parameters of the time-delayed additi...... hiện toàn bộ
Chronic β-Citronellol Inhalation Rescues Parvalbumin Expression Loss in Prefrontal Cortex of Chronic Restraint Stress Mice
Journal of Shanghai Jiaotong University (Science) - Tập 27 - Trang 512-520 - 2022
Considerable evidence has revealed that essential oils and their main constituents possess anti-depressant and anxiolytic properties. In the current study, we report the effect of β-citronellol, the main component of rose essential oil, on depressive-like and anxiety-like behaviors in chronic restraint stress (CRS) mice. We found that chronic inhalation of β-citronellol for 14 days could increase ...... hiện toàn bộ
Electric Vehicle Charging Situation Awareness for Ultra-Short-Term Load Forecast of Charging Stations
Journal of Shanghai Jiaotong University (Science) - Tập 28 - Trang 28-38 - 2023
Electric vehicles (EVs) are expected to be key nodes connecting transportation—electricity—communication networks. Advanced automotive electronics technologies enhance EVs’ perception, computing, and communication capacity, which in turn can boost the operational efficiency of intelligent transportation systems (ITSs). EVs couple the ITS to the power system, providing a promising solution to charg...... hiện toàn bộ
Full Duplex Communications for Next Generation Cellular Networks: The Capacity Gain
Journal of Shanghai Jiaotong University (Science) - Tập 23 - Trang 11-19 - 2018
Full duplex communication highly improves spectrum efficiency of a wireless communication link. However, when it is applied to a cellular network, the capacity gain from this technology remains unknown. The reason is that full duplex communication changes the aggregate interference experienced by each communication link in cellular networks. In this paper, the capacity gain from full duplex commun...... hiện toàn bộ
