The dynamics of a Leslie type predator–prey model with fear and Allee effect

Advances in Difference Equations, 2021
In this article, we discuss the dynamics of a Leslie–Gower ratio-dependent predator–prey model incorporating fear in the prey population. Moreover, the Allee effect in the predator growth is added into account from both biological and mathematical points

Unified Singularity Crossing of a 3-(rR)PS Metamorphic Parallel Mechanism through Dynamic Modeling

Machines, 2023
Metamorphic parallel mechanisms can change into multiple configurations with different motion types and mobility, which consequently yield different solutions of inverse dynamics when crossing singularity.

Force Control Improvement in Collaborative Robots through Theory Analysis and Experimental Endorsement

Applied Sciences, 2020
Due to the elasticity of their joints, collaborative robots are seldom used in applications with force control. Besides, the industrial robot controllers are closed and do not allow the user to access the motor torques and other parameters, hindering the

Hubcap and ignition switch designs - case studies in Independence Axiom

MATEC Web of Conferences, 2018
Independence Axiom offers designers a guide to good design. It declares that the design parameters (DPs) conceived for a good design must maintain the independence of the design functional requirements (FRs).
