    An Innovative Aerial Manipulator with Tandem Ducted Fans: Modeling, Control, and Simulation.Yibo Zhang, Wei Fan, Changle Xiang, Bin Xu, Tianfu Ai, Lei Yuan & Yang Liu - 2020 - Complexity 2020:1-24.
    This paper proposes an innovative ducted fan aerial manipulator, which is particularly suitable for the tasks in confined environment, where traditional multirotors and helicopters would be inaccessible. The dynamic model of the aerial manipulator is established by comprehensive mechanism and parametric frequency-domain identification. On this basis, a composite controller of the aerial platform is proposed. A basic static robust controller is designed via H-infinity synthesis to achieve basic performance, and an adaptive auxiliary loop is designed to estimate and compensate for (...)

    Analogy Lays the Foundation for Two Crucial Aspects of Symbolic Development: Intention and Correspondence.Lei Yuan & David H. Uttal - 2017 - Topics in Cognitive Science 9 (3):738-757.
    We argue that analogical reasoning, particularly Gentner's structure-mapping theory, provides an integrative theoretical framework through which we can better understand the development of symbol use. Analogical reasoning can contribute both to the understanding of others’ intentions and the establishment of correspondences between symbols and their referents, two crucial components of symbolic understanding. We review relevant research on the development of symbolic representations, intentionality, comparison, and similarity, and demonstrate how structure-mapping theory can shed light on several ostensibly disparate findings in the (...)
