NONDESTRUCTIVE ULTRASONIC INSPECTION OF COMPOSITE MATERIALS: A COMPARATIVE ADVANTAGE OF PHASED ARRAY ULTRASONIC

Nondestructive Ultrasonic Inspection of Composite Materials: A Comparative Advantage of Phased Array Ultrasonic

Carbon- and glass fiber-reinforced polymer (CFRP and GFRP) composite materials have been used in many industries such as aerospace and automobile because of their outstanding strength-to-weight ratio and corrosion resistance.The quality of these materials is important for safe operation.Nondestructive testing (NDT) techniques are an effective way t

A Two Teraflop Swarm

We introduce the Xpuck swarm, a research platform with an aggregate raw processing power in excess of two teraflops.The swarm uses 16 e-puck robots augmented with custom hardware that uses the substantial CPU and GPU processing power available from modern whole wheat phyllo dough mobile system-on-chip devices.The augmented robots, called Xpucks, ha
