International Journal of Robust and Nonlinear Control, 2023
This article proposes a three‐dimensional impact time control guidance (ITCG) law without using time‐to‐go estimation, where the constrained field‐of‐view (FOV) is also considered. The guidance law design process is divided into two steps.

Impact Time Consensus Cooperative Guidance Against the Maneuvering Target: Theory and Experiment
IEEE Transactions on Aerospace and Electronic Systems, 2023Cooperative guidance issues with impact time consensus against a maneuvering target are considered in this article. Different from the existing achievements, the expected impact time does not need to be predesigned, which is coordinated by multiple ...

Spreading Time of Impacting Nanodroplets
The Journal of Physical Chemistry B, 2021The kinematic time and maximum spreading time for the impact of nanodroplets of different types of fluids on solid surfaces with different wettability are investigated. It shows that the capillary regime still exits for the nanodroplet impact, even if viscous dissipation increases significantly when the droplet size reduces to the nanoscale.

An Optimal Geometrical Guidance Law for Impact Time and Angle Control
IEEE Transactions on Aerospace and Electronic Systems, 2023This article proposes an impact time and angle control guidance law based on geometry without estimating the time-to-go. A moving virtual target is artificially placed on the desired collision line, and the missile pursues the virtual target to satisfy ...

Impact time and angle constrained guidance via range‐based line‐of‐sight shaping
International Journal of Robust and Nonlinear Control, 2022In this article, impact time and angle constrained guidance law is proposed using a range‐based line‐of‐sight (LOS) shaping strategy. The relative motion of missile and target is described in a polar coordinate, where the LOS angle can be shaped as a ...

The Impact Factor: time for change
Australian and New Zealand Journal of Psychiatry, 2001Objective: The Impact Factor (IF) has received virtually no attention in the psychiatric literature, despite its long-term use, expanding influence and evidence of misapplication. We examine the IF's validity as a measure of a paper's scientific worth, and consider alternative ways to conduct such an appraisal.
