Based on an analytical surface potential and a simple mathematical approximation for the source depletion width, a physics-based capacitance model with closed form for silicon double-gate tunnel field-effect transistors (TFETs) is developed. Good agreements between the proposed model and the numerical simulations have been achieved, which reveal that the tunneling carriers from source have negligible...
The traditional Chan-Vese (C-V) model is sensitive to noise and inaccurate positioning of the edges in an image. This paper proposes a C-V model based on the Gaussian Laplace operator. By smoothing the image, the Gaussian smoothing function can reduce noise on the image segmentation. The Laplace operator can detect zero crossing points, and then determine the edge positions of the image. The experiments...
The limitation of exiting instruction-words software birthmark was high complexity, this paper introduced the idea of characteristics selection in text classification into the field of software birthmark, and proposed an instruction-words software birthmark selection method based on CHI ( statistics). The birthmark selection algorithm build sample program collections for protected program and extracted...
Active thermal protection techniques have been proposed for the thermal protection of induction motors. By injecting dc signals, the dc model of induction motors can be used to estimate the stator winding resistance, and thus the average stator winding temperature. The injected dc signals may lead to magnetic saturation, which may degrade a motor's performance and increase heat dissipation in the...
Motor efficiency evaluation enables the energy savings in industry. However, because of the uninterrupted characteristic of industrial processes, traditional methods defined in IEEE Std-112 cannot be used for these in-service motors. A novel nonintrusive method for in-service motor efficiency estimation based on a modified induction motor equivalent circuit has been developed by the authors. A highly...
