The MOS switch with bootstrapped technique is widely used in low-voltage switched-capacitor circuit. The switched-capacitor circuit with the bootstrapped technique could be a dangerous design approach in the nano-scale CMOS process due to the gate-oxide transient overstress. The impact of gate-oxide transient overstress on MOS switch in switchedcapacitor circuit is investigated in this work wit...

This paper presents a new mathematical model to solve cell formation problem in cellular manufacturing systems, where inter-arrival time, processing time, and machine breakdown time are probabilistic. The objective function maximizes the number of operations of each part with more arrival rate within one cell. Because a queue behind each machine; queuing theory is used to formulate the model. T...

Titanium is a highly reactive metal so that a thin layer of oxide forms on its surface whenever exposed to the air or other environments containing oxygen. This layer increases the corrosion resistance of titanium. The oxide film is electrochemically formed through anodizing. In this study, anodizing of titanium was performed in phosphate-base solutions such as H3Po4, NaH2Po4, and Na2Hpo4 at 9....
