Wire arc additive manufacturing (WAAM) is highly suitable for low-cost and high-efficiency
repair of large damaged components as a low energy consumption and sustainable …

We discuss methods to compute the flow of non-Brownian, non-cohesive, and non-spherical
rigid bodies immersed in a single homogeneous fluid. We address both the case of …

The heart of any system that simulates the physical interaction between objects is collision
detection-the ability to detect when two objects have come into contact. This system is also …

Speed and separation monitoring (SSM) allows safeguarding the operator in collaborative
robot applications by maintaining a certain minimum separation distance during operation. A …

We suggest a novel variant of Discrete Element Method (DEM) to simulate the flow dynamics
of granular material made of non-spherical particles. Our approach is limited to particles of …

In order to avoid dynamic obstacle timely during manufacturing tasks performed by
manipulators, a novel method based on distance calculation and discrete detection is …

From the optimization perspective, this article proposes a novel actual shape-based
obstacle avoidance synthesized by velocity–acceleration minimization (ASOA-VAM) scheme …

This article presents a new version of the Gilbert-Johnson-Keerthi (GJK) algorithm that
circumvents the shortcomings introduced by degenerate geometries. The original Johnson …

In three dimensional discontinuous deformation analysis (3D DDA), the contact detection
between blocks is the most expensive part in terms of the total computational cost. The …

This paper presents a geometric representation for human operators and robotic
manipulators, which cooperate in the development of flexible tasks. The main goal of this …
