To detect lung area, this paper proposes curve stopping function that is based on CT coefficient of area of lung parenchyma instead of existing edge indication function. The proposed method was compared numerically using various measures and this method can detect better lung parenchyma region than existing methods. In addition, detecting procedure of the area of lung parenchyma was visually verified in lung images.

The programming characteristics of polysilicon-aluminum oxide-nitride-oxide-silicon (SANOS) nonvolatile memory devices with Al2O3 and SiO2 stacked tunneling layers were investigated. The electron and hole drifts in the Si3N4 layer were calculated to determine the program speed of the proposed SANOS devices. Simulation results showed that enhancement of the programming speed in SANOS was achieved by utilizing SiO2 and Al2O3 stacked tunneling layers.
