Download PDF Abstract: A major challenge in Bayesian Optimization is the boundary issue (Swersky, 2017) where an algorithm spends too many evaluations near the boundary of its search space. In this paper, we propose BOCK, Bayesian Optimization with Cylindrical Kernels, whose basic idea is to transform the ball geometry of the search space using a cylindrical transformation.

Optimization of the Performance of Cylindrical Hall Thrusters. Cylindrical Hall thrusters have lower surface-to-volume ratio than conventional (annular) design Hall thrusters and, thus, seem to be more promising for scaling down. We present the results of the performance study of the cylindrical Hall thrusters with channel outer diameters of 2 ...

Reciprocating motion is a widely existing form of mechanical motion in the natural environment. Triboelectric nanogenerators (TENGs) that work in sliding mode are ideal for harnessing large-distance reciprocating motion, and their energy conversion efficiency could be greatly enhanced by adding springs to them. Herein, we focused on investigating the design and optimization principles of ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The design of reusable launch vehicles is driven by the need for minimum weight structures. Preliminary design of reusable launch vehicles requires many optimizations to select among competing structural concepts. Accurate models and analysis methods are required for such structural optimizations.
