This article mainly research on energy regeneration for the electric vehicle, analyze regeneration energy of electric vehicles in the process of braking, how we can recovery more efficient vehicles in the energy generated during braking. To calculate the efficiency by a mathematical model based on the loss of the electric vehicle motors, obtain the corresponding parameters when the efficiency is the...
Kilometers of continuous multifunctional carbon nanotube (CNT) yarns have been spun directly from chemical vapor deposition synthesis. The CNT yarn consists of multiple layers of high‐purity double‐walled CNTs stacked in seamless tubules or folded films along the yarn axis (see image). This multilayerd CNT yarn is promising for applications as engineering fibers, composites, and intelligent fabrics...
In this paper, an adaptive blind watermarking algorithm is proposed, which presents a new method of block classification based on the characteristic of visual masking of HVS (human visual system) model, including energy and variance. According to the new classification method, classify image blocks and select quantization pedometers adaptively to embed the watermark into DC component. At the same...
A kind of digital audio watermarking algorithm based on discrete wavelet transform (DWT) is proposed in the paper. In the paper, we adopt remote sensing image as watermarking image (such as satellite image). In order to enhance the remote sensing image into the audio, watermarking information is dealt with error diffusion method which is one kind of half-toning technique. Using chaos sequence for...
In this paper, a novel watermarking algorithm is proposed in Contourlet domain with ICA (independent component analysis). Contourlet transform is adopted in watermarking embedding scheme. In contrast to the wavelet transform, a kind of contour segment base are adopted to approach singular curve, and a flexible multiresolution, local, and directional expansion of an image is obtained. Watermarking...
