Abstract Anthracnose, caused by Colletotrichum sublineola , is a prevalent disease that noticeably affects global sorghum production. Nucleotide-binding leucine-rich repeat receptors (NLRs) are crucial for resistance. Here, we report the differences in number, expression profile, and gene structure of NLRs between anthracnose-resistant susceptible cultivars. Through systematic anthracnose assay on 365 accessions, identified American improved cultivar BTx623 as resistant Chinese glutinous...
Bearing fault diagnosis is of great significance for evaluating the reliability machines because bearings are critical components in rotating machinery and prone to failure. Because non-stationarity low signal-noise rate raw vibration signals, traditional methods often construct representative features via technologies feature engineering. These rely heavily on expertise inadequate actual applications. Recently, based convolutional neural networks have been studied extensively relieve...
The research of pore and permeability characteristics tight sandstone reservoirs in coal-measure is critical for gas development. In this study, the systems sandstones were studied based on low-field nuclear magnetic resonance (LF-NMR) data. was obtained by tester pulse transient method. variation with effective stress, grains, analyzed. results show that have low total porosity (2.80–4.14%), (0.51–1.56%), (0.351 × 10−6–13.910 10−6 um2). LF-NMR T2 spectra testing micropores are most...
This research presents the mathematical modelling of kinematic and complete dynamic analysis a novel over-constrained parallel mechanism, which consists two universal-prismatic-revolute joint limbs one revolute-revolute-universal limb. The model is constructed based on closed-loop vector method velocity Jacobian matrix deduced, velocity-mapping relationships between all moving components platform are also performed. Afterwards, inertia applied forces analysed, equations with classical...
Constraint forces of the kinematic pair are basis kinematics and dynamics analysis mechanisms. Exploring solution method for constraint is a hot issue in mechanism theory fields. Based on observation reciprocal screw system, system improved its procedures become easier. This also applied to procedure force. The specific expressions force represented by twist. transformation formula twist under different coordinates given it make expression more facility. A slider-crank single loop spatial...
Dynamic characteristics are studied on revolute joint with clearance of the parallelogram deployable structure in present paper. The continuous contact model based Hertz law is used for model, taking energy dissipation into account. modified Coulomb utilized calculating friction force during impact process, because able to lead difficulty numerical simulation. equations obtained by adding and dynamic this mechanical system, relevant results By analyzing these results, brings some negative...
MHD stability analysis has shown that a bean‐shaped configuration with indentation of 20% can attain second regime by additional non‐ohmic current and increasing q(0) to 1.3 or more. Recently, the increase off‐axis drive lower hybrid waves was demonstrated PBX‐M. We have studied possible paths for achieving 1.3<q(0)<2 heating simulation. identified several potential problems associated LHCD in high β βpoloidal regime. discuss approaches used encountered attaining parameters are clearly stable region.
This paper presents an effective and intuitive method for the kinematics dynamics analysis of 2UPRRRU parallel mechanism in Simulink/Simscape. Firstly, kinematic model 2UPR-RRU is analyzed based on closed loop vector method. Secondly, components Simscape are chosen to form virtual prototype mechanism, inverse solved Simulink respectively. Finally, solutions active forces actuators deduced through simulation. The result indicates possesses good movability. In addition, this provides a visual...
