Simultaneous equations are two linear equations that can be solved using bar models. By remembering that the same letter will always have the same value we can work out the missing values. To solve ...

An algebraic equation contains one or more letters in it. Each letter in the equation is called a variable. A variable can change in value. We guess at different values for each letter until our ...

Abstract: The fringe analysis method, using phase modulation with wavelength tuning, is widely used in profiling the surfaces and thickness variation in optical flat interferometry. However, the ...

Abstract: The neutron energy spectrum and fluence rate constitute critical determinants of tumor absorbed dose and therapeutic efficacy in neutron capture therapy (NCT). Variations in tumor depth and ...
