In this study, nineteen unmodified lignins from various sources (hardwood, softwood, wheat straw, and corn stover) and isolation processes (kraft, soda, organosolv, sulfite, and enzymatic hydrolysis) were used to replace 30 wt.% of petroleum-based polyol in rigid polyurethane/polyisocyanurate (PUR/PIR) foam formulations.Lignin samples were characte
Design of leakage monitoring system for photovoltaic power station based on power line communication
The fault of insulation leakage of distributed photovoltaic power decada tequila station is always the technical difficulty of photovoltaic power station.Especially in every link from the photovoltaic cell array to the grid-connected inverter, the wiring is complicated and the environment is bad.In view of the disadvantages of traditional monitorin
Intelligent Detection of Steel Defects Based on Improved Split Attention Networks
The intelligent monitoring and diagnosis of steel defects plays an important role in improving steel quality, production efficiency, and 006719f associated smart manufacturing.The application of the bio-inspired algorithms to mechanical engineering problems is of great significance.The split attention network is an improvement of the residual netwo
High-Accuracy Absolute-Position-Aided Code Phase Tracking Based on RTK/INS Deep Integration in Challenging Static Scenarios
Many multi-sensor navigation systems urgently demand accurate positioning initialization from global navigation satellite systems (GNSSs) in challenging static scenarios.However, ground blockages against line-of-sight (LOS) signal reception make it difficult for GNSS users.Steering local codes in GNSS basebands is a desirable way to correct instant
