Geometrical Defect Detection in the Wire Electrical Discharge Machining of Fir-Tree Slots Using Deep Learning Techniques
(MDPI, 2018-12-27)
Traceability is a critical issue in the manufacturing of aerospace components. However, extracting understandable information from huge amounts of data from manufacturing processes may become a very difficult task. In this ...
Historical Evolution of theWave Resource and Energy Production off the Chilean Coast over the 20th Century
(MDPI, 2018-09)
The wave energy resource in the Chilean coast shows particularly profitable characteristics for wave energy production, with relatively high mean wave power and low inter-annual resource variability. This combination is ...
The Influence of Thermal History on the Multistage Transformation of NiTi Shape-Memory Alloys
(MDPI, 2018-04)
The multistage martensitic phase transformation of a polycrystalline NiTi shape-memory alloy (50.3 at. %Ni-49.7 at. % Ti) has been studied by means of calorimetric measurements. After a conventional thermal treatment ...
