Abstract

A method for rapid and safe construction and intelligent monitoring and controlling of continuous arch bridges, which using a single-arch rib construction method, when installing a new arch rib segment, the clasp cable is immediately extended, and then using an intelligent control cable to ensure that the pier and anchorage tower are in a balanced state. The newly installed segment is no longer in a cantilever state, and the loading on the flange is very small, resulting in a small change in the tension force for the clasp cables of the previous segments. The present invention saves more than half of the clasp cable usage, reduces the number of transverse movements of the cable crane system, and significantly shortens the construction period. The construction method which using intelligent control cables to balance the unbalance loading on the middle pier, could be applied to the construction of continuous arch bridges.

Abstract

The present invention relates to a rebound composite electromagnetic energy dissipation device for reducing sloshing with a liquid-filled ball for a large liquefied natural gas (LNG) storage tank. When the liquid surface sloshes around, the gas spring is pulled by the steel strand to produce vertical displacement and provide a restoring force, and the vertical displacement of the gas spring drives the fan blades on the sleeves of the ball screws at the bottom to rotate in the damping fluid, consuming energy. The present invention uses hydraulic transmission instead of mechanical transmission of traditional piston motion, and the horizontal pistons produce horizontal displacement in the case of pressure unbalance, thus increasing the flexibility of horizontal piston motion; magnets are arranged in the horizontal slideways and the horizontal pistons to intensify the motion of the horizontal pistons and the relative motion between the horizontal pistons and the interior.

Abstract

A hierarchical control system for torque distribution of hub motor-driven electric vehicles constructs a hierarchical controller with upper and lower layers. An upper layer torque distribution controller's drive torque distribution control strategy is determined through a fuzzy control module. A lower layer torque distribution controller receives the torque, yaw velocity, and side-slip angle from the upper layer torque distribution controller and performs drive torque distribution control based on the motor efficiency map or tire slip rate by using the torque, yaw velocity, side-slip angle and actual values of vehicle feedback to obtain a generalized torque output to a wheel hub motor model for calculating to obtain a target torque and inputting it into a 7-degree-of-freedom vehicle model. The 7-degree-of-freedom vehicle model feeds back vehicle states to the upper layer torque distribution controller to form a closed-loop control, achieving energy-saving control and improving handling stability and safety.

In the disclosure, physical treatments such as ball milling and high-pressure jet homogenization treatment are conducted on alkali lignin at the early stage to adjust the molecular weight and size of alkali lignin and thus to give alkali lignin nanoparticles with uniform particle sizes; and on this basis, a chemical treatment such as alkylation grafting modification is conducted to give amphiphilic lignin nanoparticles with both hydrophilicity and lipophilicity. Due to the nano-size effect, the amphiphilic lignin nanomaterial has a significantly-increased specific surface area (SSA) and effectively-improved surface properties, which can reduce the oil-water interfacial tension, and emulsify the crude oil and peel off the crude oil from the surface of rock particles, so as to achieve the purpose of oil-solid separation.

Abstract

A hierarchical mapping-based automatic balancing storage method for a Ceph storage system. The method comprises: adding a level attribute to all object storage devices (OSD) in a storage cluster, dividing the devices into multiple sub-storage pools according to the level, adding a level attribute to placement groups (PG) by using OSD levels as a basis, and looking up an OSD combination in OSD sub-storage pools having the same level as PGs for storage; meanwhile, adding a random factor and an impact factor to guide the process in which the PGs select the OSDs; determining a PG large migration direction according to usage information about storage pools where the PGs are located and other storage pools when the usage of a single-point OSD in the total storage pool is too high, while adjusting the migration balance according to a combination of PG level, random factor and impact factor. According to the method, OSDs with excessively high usage within the Ceph storage system can reasonably migrate internal PGs so as to ensure that the system storage is balanced, and the system stability is improved.

Abstract

A method for quantitatively measuring mixed component CdS/ZnS quantum dots in plant root epidermal tissue, comprising: washing a plant root part and then drying same, and coating a solution of mixed component CdS/ZnS quantum dots that have different surface ligands; performing laser-induced nanosecond time-resolved fluorescence spectrum detection on the epidermis of the plant root to obtain fluorescent spectra; scanning fluorescent spectra of different quantum dots to obtain a derivative fluorescent spectrum, and establishing a standard curve of fluorescence intensity and concentration of the different quantum dots in the epidermis of the plant root. The present method combines and uses a nanosecond time-resolved fluorescence spectroscopy method with a constant matrix derivative synchronous fluorescence spectroscopy method, which may not only effectively eliminate the interference of self-generating fluorescence signals of a surface of the plant root, but may also simultaneously achieve the in-situ quantitative analysis of mixed component quantum dots adsorbed by the epidermis of the plant root. The present method is highly accurate, and has good stability, and excellent recovery and selectivity. Meanwhile, the present method will not damage plants and may be used to perform plant living detection.
