A Series of Vertical Deflections, a Promising Traffic Calming Measure: Analysis and Recommendations for Spacing
(MDPI, 2020-05-13)
Traffic calming measures (TCM) are placed in urban areas to improve road safety, and among them, vertical TCMs are widely employed. Many researches are focused on the influence of the geometry of each measure on speed ...
Advances in the Study of the Behavior of Full-Depth Reclamation (FDR) with Cement
(MDPI, 2019-08-01)
Road maintenance and rehabilitation are expected to meet modern society's demands for sustainable development. Full-depth reclamation with cement as a binder is closely linked to the concept of sustainability. In addition ...
Bitumen modified with recycled polyurethane foam for employment in hot mix asphalt
(Universidad Nacional de Colombia, 2018-04)
A wide variety of modifiers have been applied to bitumen in order to enhance their properties and performance. Among them, polymers have been mainly used. The aim of this paper is to assess the use of polyurethane foam ...
Semi-Active Magnetorheological Damper Device for Chatter Mitigation during Milling of Thin-Floor Components
(MDPI, 2020-07-31)
The productivity during the machining of thin-floor components is limited due to unstable vibrations, which lead to poor surface quality and part rejection at the last stage of the manufacturing process. In this article, ...
Special Issue on “Machining Dynamics and Parameters Process Optimization”
(MDPI, 2020-12-14)
In 1907, F.W Taylor—the father of production engineering—exposed the fundamentals of modern machining and defined chatter as the most obscure and delicate of all problems facing the machinist [...]
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 ...
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 ...
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 ...
A reliable turning process by the early use of a deep simulation model at several manufacturing stages
(MDPI, 2017-05-02)
The future of machine tools will be dominated by highly flexible and interconnected systems, in order to achieve the required productivity, accuracy, and reliability. Nowadays, distortion and vibration problems are easily ...
