A framework for human-robot interaction with a mobile and telepresence enabled anthropomorphic robot
Published 2021“…Past software frameworks for similar platforms were limited by a focus only on the navigation aspect, neglecting the gesticulation and conversation aspects or simply multiple iterations of the same robot. This thesis describes the conceptualization of a framework that unifies the navigation, gesticulation and conversation aspects with adjustable autonomy. …”

Robust discrete geodesic and its applications in digital geometry processing
Published 2013“…In contrast to the existing approaches which compute the distance from source to destinations in a single Dijkstra-like sweep, our method proceeds in an iterative and global manner. Thanks to its global nature, the resulting distance is tolerant to some defects (e.g. holes, gaps, shortcuts), insensitive to mesh tessellation/resolution, and robust to noise, which provides a meaningful approximation of geodesics on broken meshes. 3) The third contribution is about potential applications of our above algorithms in digital geometry processing, especially for the motion data captured by 3D structure light camera that inevitably has several kinds of defects such as noise, holes, gaps, etc. …”

Enhancing convexification techniques for solving nonconvex quadratic programming problems
Published 2017“…Most global optimization approaches for nonconvex QCQPs are based on constructing a convex or linear relaxation of the problem, and embedding it within an exhaustive search mechanism, where a lower bound is calculated as the value of the objective function of this relaxation (for a minimization problem) at each iteration of the search tree. The two principle elements affecting the overall effectiveness of such exhaustive search methods are the tightness of the underlying relaxation and the efficiency of calculating the lower bound. …”
