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 ...
Design and Fabrication of a Phase Change Material Heat Storage Device for the Thermal Control of Electronics Components of Space Applications
(MDPI, 2022-02-28)
In this paper, the design and validation of a heat storage device based on phase change materials are presented, with the focus on improving the thermal control of micro-satellites. The main objective of the development ...
Analysis of the dressing process using stationary dressing tools
(Elsevier, 2017)
Grinding process is a very important process in machining industry to manufacture high quality part. The correct preparation of grinding wheel involves dressing process taking importance to optimize grinding process. Due ...
Mechanical Properties of Three Bamboo Species: Effect of External Climatic Conditions and Fungal Infestation in Laboratory Conditions
(MDPI, 2022-12-07)
Bamboo is a material with good tensile and flexural resistance. As a construction material with structural capacity, using bamboo implies considerable environmental advantages in relation to other typical materials such ...
Lamellar Spacing Modelling for LPBF Aluminum Parts
(MDPI, 2022-12-17)
The high cooling rates reached during metal additive manufacturing (MAM) generate microstructures very different from those obtained by other conventional manufacturing methods. Therefore, research about the modeling of ...
Influence of the Measurements Uncertainties in the Correlation of Spacecraft Thermal Models against Thermal Results
(MDPI, 2022-12-14)
Ground thermal tests are always mandatory before any space mission is flown into space. The collected results of these tests are mainly temperatures of the different parts of the spacecraft (nodes) for different mission ...
Heat waves risk assessment of historic urban areas: historic buildings and their urban environment
(2022-11-11)
Climate change impacts such as extreme events and progressive global warming are threatening the conservation and liveability of urban cultural heritage. Understanding climate risks on heritage should be part of policy and ...
Machining Stresses and Initial Geometry on Bulk Residual Stresses Characterization by On-Machine Layer Removal
(MDPI, 2020-03-22)
Prediction and control of machining distortion is a primary concern when manufacturing monolithic components due to the high scrap and rework costs involved. Bulk residual stresses, which vary from blank to blank, are a ...
