In Monte Carlo simulations, the more particles you trace, the more accurate results you get. While recent improvements in hardware and software have feasible on personal computers, it can still take hours, even days to achieve a statistically meaningful result. Geant4 is a kind of Monte Carlo simulation tool solving the problem in nuclear physics. It can be used to accurately simulate the passage...
A compact multi-detector SPECT system for small animal (MicroSPECT) has been developed. The detector of MicroSPECT system is composed of a NaI scintillation crystal array and four H8500 flat panel position sensitive photon multiplier tubes(PS-PMT). The pixel size of the scintillation crystal array is 1.45 mmtimes1.45 mm and the total detection area is 103.75 mmtimes103.75 mm with 61times61 pixels...
While process variations are becoming more significant with each new IC technology generation, they are often modeled via linear regression models so that the resulting performance variations can be captured via normal distributions. Nonlinear response surface models (e.g., quadratic polynomials) can be utilized to capture larger scale process variations; however, such models result in nonnormal distributions...
