Seeding streamlines in 3D flow fields without considering their projections screen space can produce visually cluttered rendering results. Streamlines will overlap or intersect with each other the output image, which makes it difficult for user to perceive underlying structure.

In our algorithm, 2D images depth maps generated by variety visualization techniques...

For the target-tracking problem, full state of target may not be available since it expensive or impossible to obtain. Thus, needs reconstructed estimated only according measured inputs and outputs. The case that all followers can measure directly yields study distributed methods, thus reducing communication computation resource while resulting in more robustness. This article confronts these problems by addressing a iterative finite impulse response (DIFIR) consensus filter for...

Abstract This article addresses the problem of dynamic event‐triggered asynchronous output feedback controller design for discrete‐time switched systems under deception attacks. To conserve communication resources and restrict time, a mechanism is established which permits system to switch many times in trigger interval. Then, stability criteria underlying despite impact attacks are obtained via Lyapunov function average dwell time method. Meanwhile, co‐design scheme gains parameters...
