Planning of Safe Kinematic Trajectories for Free Flying Robots Approaching an Uncontrolled Spinning Satellite

The problem of planning a safe trajectory for a free-flying robot to approach an uncontrolled spinning satellite is addressed. First, a heuristic plan is presented for a simple planar case, which constructs a collision-free path within realistic system constraints. Second, a general numerical optimization technique for planning a safe spatial trajectory is presented. In it, the approach path is...

Visualisation of Collaborative Ion Trajectories on Grid Technologies

Our perceptive of the scientific datasets has largely relied on numerical and statistical analysis of data from experimental dimension and computer simulation result. In particular, we consider a simulated 3D time-varying model of scientific datasets and examine the temporal and collaboration among datasets. Our goal is to contrive effective visual representations to assist scientists in ascert...

IBiSA_Tools: A Computational Toolkit for Ion-Binding State Analysis in Molecular Dynamics Trajectories of Ion Channels

Ion conduction mechanisms of ion channels are a long-standing conundrum. Although the molecular dynamics (MD) method has been extensively used to simulate ion conduction dynamics at the atomic level, analysis and interpretation of MD results are not straightforward due to complexity of the dynamics. In our previous reports, we proposed an analytical method called ion-binding state analysis to s...

Polymethylmethacrylate/Polyacrylonitrile Membranes via Centrifugal Spinning as Separator in Li-Ion Batteries

Electrospun nanofiber membranes have been extensively studied as separators in Li-ion batteries due to their large porosity, unique pore structure, and high electrolyte uptake. However, the electrospinning process has some serious drawbacks, such as low spinning rate and high production cost. The centrifugal spinning technique can be used as a fast, cost-effective and safe technique to fabricat...
