Modeling x-ray absorption near edge structure (XANES) requires computationally intensive calculations. We show that parallel processing can reduce the time required for XANES calculations by a factor of up to 50 over standard desktop computers. Paral

We describe a new generation of thermal sensors for the measurement of ac voltages at frequencies up to 100 MHz. Electronics grade fused silica has been selected as a substrate material because it is significantly more robust than the previous genera
