Uncharted Stable Peninsula for Multivariable Milling Tools by High-Order Homotopy Perturbation Method
(MDPI, 2020-11-06)
In this work, a new method for solving a delay differential equation (DDE) with multiple delays is presented by using second- and third-order polynomials to approximate the delayed terms using the enhanced homotopy ...
Estimation of the Heat Loss Coefficient of Two Occupied Residential Buildings through an Average Method
(MDPI, 2020-11-02)
The existing performance gap between the design and the real energy consumption of a building could have three main origins: the occupants’ behaviour, the performance of the energy systems and the performance of the building ...
Vision-Based Hybrid Controller to Release a 4-DOF Parallel Robot from a Type II Singularity
(MDPI, 2021-06-13)
The high accuracy and dynamic performance of parallel robots (PRs) make them suitable to ensure safe operation in human–robot interaction. However, these advantages come at the expense of a reduced workspace and the possible ...
