Corner accuracy occurring in wire electrical discharge machining (WEDM) is influenced by parameters such as vibration, lag, and excessive discharge, etc. This study proposed an optimization method which can improve the corner of WEDM process. The pulse-on time (ON), pulse-off (OFF), open circuit voltage (OV), servo (SV), tension (WT), flushing pressure (WA) were selected to investigate influenc...

this paper proposes a low voltage (±0.55v supply voltage) low power (44.65µw) high common mode rejection ratio (cmrr) differential amplifier (d.a.) with rail to rail input common mode range (icmr), constant transconductance (gm) and enhanced frequency performance. its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

Corners in images represent a lot of important information. Extracting corners accurately is significant to image processing, which can reduce much of the calculations. In this paper, two widely used corner detection algorithms, SUSAN and Harris corner detection algorithms which are both based on intensity, were compared in stability, noise immunity and complexity quantificationally via stabili...

The importance of smooth mould filling in the foundry casting process has been recognized for a long time. More uniform the filling process is, the better the quality of the casting of the products produced. Successful computer simulations can help to reduce the number of trials and cut down the lead time in the design of new casting products by better understanding the complex mechanisms and i...

Corners in images represent a lot of important information. Extracting corners accurately is significant to image processing, which can reduce much of the calculations. In this paper, three widely used corner detection algorithms, FAST (Features from Accelerated Segment Test), Eigen Value and Harris corner detection algorithms which are all based on intensity, were compared in stability, noise ...

Abstract The effect of colloidal silicon dioxide (CSD) on powder flow properties poor-flowing excipient lactose 200 M was investigated. Binary mixtures different ratios CSD as glidant were examined using a modern image-based measuring technique. Special attention placed to subtle variations in from small changes concentration (0.025% w/w). Understanding the modes interaction particles and their...
