Effect of SiC-Cu Electrode on Material Removal Rate, Tool Wear and Surface Roughness in EDM Process [PDF]

open access: yesEngineering and Technology Journal, 2020
Electrical discharge machining (EDM) is one of the most common non-traditional processes for the manufacture of high precision parts and complex shapes. The EDM process depends on the heat energy between the work material and the tool electrode.

Advanced statistics: Understanding Medical Record Review (MRR) Studies [PDF]

open access: yesAcademic Emergency Medicine, 2004
Medical record review (MRR) studies have been reported to make up 25% of all scientific studies published in emergency medical (EM) journals. However, unlike other study designs, there are no standards for reporting MRRs and very little literature on the methodology for conducting them.
