[1]School for Engineering of Matter, Transport, and Energy, Arizona State University, Tempe, AZ, USA
[2]Chemistry Department, United States Naval Academy, Annapolis, MD, USA

Flexible electronics are temporarily affixed to a rigid carrier such as glass or silicon prior to device fabrication to facilitate robotic handling of the device, but also to allow optical lithography to stay within overlay design registration budget; without the rigid carrier, a ... Read More

Demonstration of All-Optical NAND Logic Gate Using Photonic Integrated Circuits

J. T. Andrews[1], R. Choubey[1], O P Choudhary[1], N. Malviya[1], A. Patel[1], M. Kumar[1], S. Chouksey[1], J. Solanki[1]
[1]National MEMS Design Center, Department of Applied Physics, Shri G S Institute of Technology & Science, Indore 452003 MP, India

A logic gate performs a certain Boolean logic operation on one or more logical inputs and produces a single logical output. The logic values are either “true” or “false.” Logic gates are bistable devices, that is, they may yield one of these two possible stable outputs. The NAND logic is ... Read More

Numerical Prediction of Weld Bead Geometry in Plasma Arc Welding of Titanium Sheets

V. Dhinakaran[1], S. Khope[1], N. S. Shanmugam[1] , K. Sankaranarayanasamy[1]
[1]National Institute of Technology, Tiruchirappalli, Tiruchirappalli, Tamil Nadu, India

Plasma Arc Welding (PAW) is one of the important arc welding processes commonly used in electronics, medical, automotive and aerospace industries due its high accuracy, finishing, and ability of welding any hard materials. It is an extension of Tungsten Inert Gas welding (TIG or GTAW). ... Read More
