Statistical Motion Mask and Sliding Registration [PDF]

open access: yes, 2018
Accurate registration of images depicting respiratory motion, e.g. 4DCT or 4DMR, can be challenging due to sliding motion that occurs between the chest wall and organs within the pleural sac (lungs, mediastinum, liver). In this paper we propose a methodology that (1) segments one of the images to be registered (the source or floating/moving image) into

Sliding mode control for slosh-free motion using nonlinear sliding surface [PDF]

open access: yes2009 European Control Conference (ECC), 2009
A new nonlinear switching surface is proposed for the design of a sliding mode controller for a class of mismatched uncertain systems. A control system for slosh-free motion of a partially filled liquid container is sought. This is representative of a broader class of systems to which the proposed methodology is applicable.

Modeling and analysis of sliding motion of arc root along OGW during lightning strike

open access: yes电力工程技术
Overhead ground wire (OGW) is an important equipment to prevent transmission wire from being struck by lightning. When OGW is struck by lightning, the sliding motion of arc root causes different damage mechanism. Therefore, it is necessary to analyze the
