Title: Bone Mechanics Objectives:- -To become familiar with LabView software and National Instruments‚ in order to record and observe the strain signals from chicken bone and an aluminum rod. Background: Data acquisition is the use of computer software connected to a measuring device. Signals and measurements are recorded‚ which is converted into a digital signal only understood by a computer. Data is recorded at a certain speed that is processed in real time‚ and can be immediately interpreted

Springer October. 12‚ 2012 George Washington Carver was born in January 1864 into slavery in Diamond‚ Missouri. His master Moses Carver was a German American immigrant who brought George’s parents Mary and Giles. George had 10 brothers and sisters who all died prematurely. When George was only a week old‚ he was kidnapped along with his mother and sister‚ George’s older brother James got to safety though. The raiders sold the stolen slaves in Kentucky. Moses Carver hired a man named John Bentley to find

CBE 6333‚ R. Levicky 1 Potential Flow Part I. Theoretical Background. Potential Flow. Potential flow is frictionless‚ irrotational flow. Even though all real fluids are viscous to some degree‚ if the effects of viscosity are sufficiently small then the accompanying frictional effects may be negligible. Viscous effects become negligible‚ for example‚ for flows at high Reynolds number that are dominated by convective transport of momentum. Thus potential flow is often useful for analyzing external
