Statistical Approach for the Design of Structural Self-Compacting Concrete with Fine Recycled Concrete Aggregate
The compressive strength of recycled concrete is acknowledged to be largely conditioned by the incorporation ratio of Recycled Concrete Aggregate (RCA), although that ratio needs to be carefully assessed to optimize the ...
Special Issue on “Machining Dynamics and Parameters Process Optimization”
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 [...]
Evaluating Disruptive Innovation Project Management Capabilities
Firms must adapt to a business environment in constant flux. Economic and political factors and the constant interruption of new technologies force firms and organizations to change and to adapt, so that they are not left ...
A reliable turning process by the early use of a deep simulation model at several manufacturing stages
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 ...
Experimental evaluation of cement mortars with recycled brass fibres from the electrical discharge machining process
This paper aims to evaluate the effect of recycled brass fibres on the physical, thermal and mechanical properties of cementitious mortars. For that purpose, seven different mortars, with the same water/cement ratio but ...
CO2 cryogenic milling of Inconel 718: cutting forces and tool wear Author links open overlay panel
Machining Inconel 718 alloy is a challenge due to its low machinability. This thermal resis-tant alloy combines high strength even at high temperatures with strain hardening tendency that causes high forces and extreme ...
Automatic Analysis of Archimedes’ Spiral for Characterization of Genetic Essential Tremor Based on Shannon’s Entropy and Fractal Dimension
Among neural disorders related to movement, essential tremor has the highest prevalence; in fact, it is twenty times more common than Parkinson's disease. The drawing of the Archimedes' spiral is the gold standard test to ...
On the Analysis of Speech and Disfluencies for Automatic Detection of Mild Cognitive Impairment
Alzheimer's disease is characterized by a progressive and irreversible cognitive deterioration. In a previous stage, the so-called Mild Cognitive Impairment or cognitive loss appears. Nevertheless, this previous stage does ...
On-Line Monitoring of Blind Fastener Installation Process
Blind fasteners are of special interest for aircraft construction since they allow working on joints where only one side is accessible, as is the case in many common aerospace box-type structures, such as stabilizers and ...
Thermomechanical analysis of additively manufactured bimetallic tools for hot stamping
A comparison between a conventional AISI H13 hot stamping tool and a bimetallic tool consisting of an AISI 1045 core and a laser-deposited AISI H13 coating is performed. In order to analyze the performance of bimetallic ...
