| 1 | Formation-Containment Control Using Dynamic Event-Triggering Mechanism for Multi-Agent Systems显示文摘The paper proposes a novel approach for formationcontainment control based on a dynamic event-triggering mechanism for multi-agent systems.The leader-leader and follower-follower communications are reduced by utilizing the distributed dynamic event-triggered framework.We consider two separate sets of design parameters:one set comprising control and dynamic event-triggering parameters for the leaders and a second set similar to the first one with different values for the followers.The proposed algorithm includes two novel stages of codesign optimization to simultaneously compute the two sets of parameters.The design optimizations are convex and use the weighted sum approach to enable a structured trade-off between the formation-containment convergence rate and associated communications.Simulations based on non-holonomic mobile robot multi-agent systems quantify the effectiveness of the proposed approach. | Amir Amini Amir Asif Arash Mohammadi | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，5： | 15 |
| 2 | Weathering and soils formation on different parent materials in Golestan Province,Northern Iran显示文摘Geochemical,mineralogical,and micromorphological characteristics of soils and their relevant parent rocks including loess,ignimbrite,sandstone and limestone were investigated to identify the soil-parent material uniformity and the weathering degree of soils in Golestan Province,northern Iran.Highly developed Calcixerolls and moderately developed Haploxerepts were formed on loess and limestone,respectively.In contrast,the soils formed on ignimbrite and sandstone were nondeveloped Entisols.Illite was the dominant clay mineral found in ignimbrite and sandstone in both the A horizon and parent material.In loess derived soils however,smectite was dominant especially in the Bt horizon compared to its parent material indicating partly to its pedogenic formation.In limestone,illite and vermiculite were dominant both in the A and C horizons.Ti/Zr ratio proved that the studied soils were closely related to their underlying parent materials geochemically.Chemical index of alteration(CIA),micromorphological index of soil development(MISECA),smectite/illite+chlorite ratio and magnetic susceptibility were applied to investigate the degree of soil development.Results showed that the most and the least developed soils were those formed on loess deposits and limestone,respectively.Application of the different geochemical and pedogenetic approaches was proved to be useful in identifying the relevance of soils to their underlying parent materials and also their degree of development. | Maryam MAHMOODI Farhad KI-IORMALI Arash AMINI Shamsollah AYOUBI | 2016 | Journal of Mountain Science2016，13，5： | 6 |
