Abstract: A centralized cooperative positioning method includes: caching measurements of nodes in multiple time slices up to the current time slice; calculating location information of the nodes in the multiple time slices to obtain trajectory of the nodes in the multiple time slices; performing initial state estimations of the nodes based on measurements of a single time slice; and using the initial state estimations as initial solution values, performing the joint time-space processing on the measurements of the nodes in the multiple time slices based on trajectory constraints, to obtain a state estimation of each node at the current time slice, in which the state estimation includes an estimated value of a location of the node.

A system includes a water tank, a water pump, a biochemical reaction zone, a hydrolytic acidification tank and other devices.

Abstract: The present disclosure relates to a three-dimensional (3D) printing ink for Pleurotus eryngii and a preparation method for and use of the 3D printing ink and a preparation method for 3D printed food of Pleurotus eryngii. The present disclosure adopts Pleurotus eryngii freeze-dried powder which reduces a moisture content of Pleurotus eryngii. In addition, the problem that the Pleurotus eryngii with high fiber content blocks a nozzle for 3D printing can be solved by making the Pleurotus eryngii into small particle powder, and bioactive substances in the Pleurotus eryngii can be retained as much as possible. The addition of hydrocolloid can improve rheological properties of the Pleurotus eryngii freeze-dried powder, which increases viscosity of the 3D printing ink for Pleurotus eryngii, and enhances mechanical strength of the 3D printing ink, such that the ink can maintain the print shape and is not easy to collapse.

Abstract: An aircraft anti-icing composition is provided comprising a freezing point depressant and a thickener comprising nanocrystalline cellulose. A thickening composition is also provided comprising nanocrystalline cellulose. Also taught is the use of nanocrystalline cellulose in the manufacture of an anti-icing composition and the use of nanocrystalline cellulose in a thickening composition.

Abstract: A water flooding composition in a method of secondary hydrocarbon recovery. The water flooding composition includes water and a thickening polymer. The thickening polymer includes a hydroxyethyl cellulose backbone polymer having a molecular weight of between about 1,000,000 and about 2,000,000 and a hydrophobic modifier. The hydrophobic modifier has a substitution level in the thickening polymer of between about 0.1 percent and about 2 percent by weight of the thickening polymer. The hydrophobic modifier is an alkyl hydrocarbon based material containing between about 10 and about 24 unsubstituted carbon atoms per group. The thickening polymer has a concentration in the water flooding composition of between about 0.01 percent and about 1 percent by weight of the water flooding composition. The water flooding composition is formulated within these ranges so that the water flooding composition has a suitable viscosity/mobility and so that the water flooding composition is injectable.
