Topology Synthesis of Hybrid Space Control Mechanism Based on FIS Theory

open access: yesIEEE Access, 2023
Driven by the significant demand for space control mechanism in the development of national space field, topology synthesis method for the hybrid mechanism based on finite and instantaneous screw (FIS theory) is studied in this paper.

Hybrid Models for Human Motion Recognition [PDF]

open access: yes2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'05), 2005
Probabilistic models have been previously shown to be efficient and effective for modeling and recognition of human motion. In particular we focus on methods which represent the human motion model as a triangulated graph. Previous approaches learned models based just on positions and velocities of the body parts while ignoring their appearance ...

Rate-distortion performance of dual-layer motion compensation employing different mesh densities [PDF]

open access: yes, 2006
We describe a dual layer algorithm for mesh-based motion estimation. The proposed algorithm, employing meshes at different scales, aims to improve the rate-distortion performance at fixed bit rates.

Stiffness-Performance-Based Redundant Motion Planning of a Hybrid Machining Robot

open access: yesMachines, 2022
Large-scale components usually have complex structures with high local stiffness, and the holes on them are required to be machined with high precision, which makes it important and challenging to study how to efficiently and precisely drill in the large-

Homoclinic and heteroclinic motions in hybrid systems with impacts [PDF]

open access: yesMathematica Slovaca, 2017
Abstract In this paper, we present a method to generate homoclinic and heteroclinic motions in impulsive systems. We rigorously prove the presence of such motions in the case that the systems are under the influence of a discrete map that possesses homoclinic and heteroclinic orbits.

Respiratory organ motion in interventional MRI : tracking, guiding and modeling [PDF]

open access: yes, 2014
Respiratory organ motion is one of the major challenges in interventional MRI, particularly in interventions with therapeutic ultrasound in the abdominal region. High-intensity focused ultrasound found an application in interventional MRI for noninvasive

Novel hybrid visual stimuli incorporating periodic motions into conventional flickering or pattern-reversal visual stimuli for steady-state visual evoked potential-based brain-computer interfaces

open access: yesFrontiers in Neuroinformatics, 2022
In this study, we proposed a new type of hybrid visual stimuli for steady-state visual evoked potential (SSVEP)-based brain-computer interfaces (BCIs), which incorporate various periodic motions into conventional flickering stimuli (FS) or pattern ...
