Hewidy et al. (2005) correlated the various WEDM parameters such as peak current, duty factor, wire tension, and water pressure with the performance outputs namely metal removal rate (MRR), wear ratio and surface roughness in WEDM of Inconel 601.
Kumar et al. (2012) evaluated the machining effectiveness with PMEDM on Inconel- 718 and examined the effect of input variables, i.e. polarity, tool material, peak current, duty cycle, gap voltage, and powder particles on machining efficiency.
Hewidy et al. (2005) developed a mathematical model based on response surface methodology for correlating the relationships of various WEDM parameters of Inconel 601 material such as peak current, duty factor, wire tension and water pressure on the MRR, wear ratio and surface roughness.
The recovered DNA was sheared into paired-end and mated-pair libraries (Corvaris S2, Paired-end: peak power 50.0, duty factor 10.0, cycle per burst 200, time per run 90 s; Mated-pair: duty cycles 20%, intensity 0.1, cycle per burst 100, time per run 5 min), and purified (Paired-end: Dynal magnetic M 280-streptavidin beads, Mated-pair: Agencourt AMPure XP beads).
Spatter deposition and hole diameter increase with increasing laser peak power and duty cycle.
Pulsed plasma deposition significantly lowers the deposition substrate temperature as the peak power and duty ratio decrease.
The microstructure analysis executed through SEM and corresponding EDS revealed that the peak current and duty factor has significant effect on the morphology of the coating.
We sonicated 20 μg of DNA to an average size of 200 bp on a Covaris S220 (MicroTUBE AFA Fiber; peak power 175; duty factor 10; cycles/burst 200; 280 s) and fragments of size 150 250 bp were purified from a 3%% MetaPhor gel (Lonza) using Qiaquick columns (Qiagen).
In this work, the influence of pulsed power supply parameters such as duty cycle, peak voltage, peak current and time averaged current is studied in an ASPN setup, on nitrided layer phase composition and surface hardness of austenitic stainless steel (ASS).
Police plan a huge security operation during the Games, with 12,500 officers on duty at peak periods.
