Neural Collaborative Filtering for Chinese Movies Based on Aspect-Aware Implicit Interactions

IEEE Access, 2022
Aspect information mining from user comments has become an important means to improve the performance of recommendation systems (RSs). This is because aspect information in comments is fine-grained and tends to reflect the interactions and preferences of

Contact Analysis of Mobility Devices Based on Tension

Modelling, 2021
Advances in space technology have opened up opportunities for human beings to work in outer space. It is expected that the upsizing of manned space facilities, such as the International Space Station, will further this trend.

Motion analysis method considering non-smooth contact between an ANCF-based skin model and a rigid body

Nihon Kikai Gakkai ronbunshu
In this study, we propose a motion analysis method for human skin that considers non-smooth contact with rigid objects. The motivation stems from the need for safe and efficient development of human–machine contact systems, particularly in caregiving and

Study of vehicle-terrain interaction based on ANCF

IOP Conference Series: Materials Science and Engineering, 2017
A brief review of the empirical and analytical models are presented. The pressure-sinkage relationship proposed by Bekker and the tractive performance (drawbar pull-slip) of vehicle is set up. A figure of drawbar pull vs. slip at different time and slip is illustrated.

Adaptive Control of Space Robot Despinning Tumbling Target Using Flexible Brushes

International Journal of Aerospace Engineering, 2021
A flexible brush mechanism is designed and mounted at the end of a seven-degree-of-freedom robotic arm to despin a tumbling target. The dynamics model of the flexible brush is established using the absolute nodal coordinate method (ANCF), and its contact

General Conversion between ANCF and B-spline Surfaces

CoRR
In this paper, general conversion equations are derived between Absolute Nodal Coordinates Formulation (ANCF) finite surface elements and B-spline surfaces, an extension of our previous work on the conversion between ANCF cable elements and B-spline curves.
