A multi-aircraft conflict detection and resolution method for 4-dimensional trajectory-based operation

引用

Chinese Journal of Aeronautics 2018年第7期31卷 1579-1593页

作者： Siqi HAO Shaowu CHENG yaping zhang School of Transportation Science and Technology Harbin Institute of Technology

Conflict Detection and Resolution（CD＆R） is the key to ensure aviation safety based on Trajectory Prediction（TP）. Uncertainties that affect aircraft motions cause difficulty in an accurate prediction of the trajectory, especially in the context of four-dimensional（4D） Trajectory-Based Operation（4DTBO）, which brings the uncertainty of pilot intent. This study draws on the idea of time geography, and turns the research focus of CD＆R from TP to an analysis of the aircraft reachable space constrained by 4D waypoint constraints. The concepts of space–time reachability of aircraft and space–time potential conflict space are proposed. A novel pre-CD＆R scheme for multiple aircraft is established. A key advantage of the scheme is that the uncertainty of pilot intent is accounted for via a Space-Time Prism（STP） for aircraft. Conflict detection is performed by verifying whether the STPs of aircraft intersect or not, and conflict resolution is performed by planning a conflict-free space–time trajectory avoiding intersection. Numerical examples are presented to validate the efficiency of the proposed scheme.

Soil-Air Partitioning of Polychlorinated Biphenyls and Total Dichloro-Diphenyl-Trichloroethanes

引用

Journal of Earth Science 2014年第4期25卷 741-748页

作者： yaping zhang Erping Bi Honghan Chen School of Water Resources and Environment China University of Geosciences (Beijing) Beijing Key Laboratory of Water Resources and Environment Engineering China University of Geosciences (Beijing)

Soil-air partitioning is an important diffusive process that affects the environmental fate of organic compounds and human health. In this review, factors affecting the soil-air partitioning of polychlorinated biphenyls （PCBs） and total dichloro-diphenyl-trichloroethanes （p,p＇- and o,p＇- isomers of DDT, DDD, and DDE） are discussed. Hydrophobicity is an important factor that influences soil-air partition coefficients （KsA）, and its effect can be explained through enthalpy of phase change for soil-air partitioning transfer （AHsA）. For more hydrophobic compounds, a sharp increase in the KSA of PCBs and organochlorines can be seen in the early aging period. During the aging period, the temperature has a significant effect on the more hydrophobic organic compounds. The content and properties of soil or- ganic matter influence the KSA of the target compounds. Generally, KSA decreases with increasing rela- tive humidity in soils. The linear trend between KSA and temperature （T） changes at 0 ~C. Freezing the air or soil in experiments would change the research results. On the basis of factors influencing soil-air partitioning, a multipleparameter （T, organic carbon fraction （foe）, and octanol-air partition coefficient （KoA）） model is put forward to predict the KSA values for PCBs and total DDTs.

This work provides a general method for preparing monodisperse, water-soluble and paramagnetic magnetic nanoparticles which are easy to be modified. Firstly, magnetic silica with core-shell structure was prepared according to a previous work. Then, the magnetic silica was treated with alkali solution to afford magnetic nanoparticles. With the increase of calcination temperature for the preparation of magnetic silica, the crystallinity and the magnetic responsibility of magnetic silica strengthened, meanwhile, the corresponding magnetic nanoparticles kept monodisperse without any aggregation. The magnetic nanoparticles are comprised of cobalt ferrite and a silica coating. The silica coating on the cobalt ferrite facilitates the magnetic nanoparticles well-dissolved and monodisperse in water, and easilv modified.
