A novel three-dimensional device structure for a carbon nanotube (CNT) fin field-effect transistor (FinFET) is proposed and evaluated. We evaluated the potential of the CNT FinFET compared with a Si FinFET at a 22-nm node at the circuit level using three performance metrics including propagation delay, total power dissipation, and energy-delay product (EDP). Compared with a Si FinFET, the CNT FinFET...
The speed of frequency response of all published carbon nanotube (CNT) integrated circuits (ICs) is far from that predicted. The transient response of CNT ICs is explored systematically through the combination of experimental and simulation methods. Complementary field-effect-transistor (FET) based inverters were fabricated on a single semiconducting CNT, and the dynamic response measurement indicates...
A novel mean shift algorithm of video images is proposed to track moving target in dynamic scene. The global compensation method is used to eliminate the background diversity caused by the motion of camera. Then the target is detected by difference algorithm and segmented by MRF method, so we can get the target template automatically. Finally mean shift is used to track moving target. This method...
Moving target extraction plays a prominent role in the whole target tracking process in image sequences with dynamic scene. This paper presents a new approach for moving target extraction. In order to automatically extract moving target and improve the accuracy, level set method is applied to extract moving target contour. Firstly, moving target is detected by difference algorithm. Secondly, Chan-Vese...
In this paper, we propose a kind of global motion estimation algorithm based on feature matching. The scale invariant feature transform (SIFT) algorithm is applied to global motion estimation. The feature extracted by SIFT algorithm is invariant to image scale and rotation. The matching accuracy is very high even under the condition of additive noise, varying illumination and affine deformation. It...
This paper proposes a spherical underwater vehicle which is propelled by water-jetted motors. It has many characteristics such as small size, light weight, flexibility of motion and noiselessness. In this paper, the dynamics model of the vehicle is analysed according to its design; and the vehicle's dynamics model is developed. The dynamics model of propellers for the vehicle is also analysed for...
