Compute resonances of a one-dimensional potential obtained by taking a spline with value VV(i) at each point xx(i). The behavior at the end points is chosen according to the "not-a-knot" condition if the end values are zero, the resulting (compactly supported) spline will be C^1 at the end points.

A new autonomous underwater vehicle (AUV) called H160 is described in this article. The first prototype of this AUV has been realized through collaboration between two partners, which are the Laboratory of Data processing, Robotics and Micro electronic of Montpellier (LIRMM) and the ECA‑ HYTEC (specialist in the de‑ sign and manufacture of remote controlled systems in “hostile” environments). Thispaper shows a general presentation of the vehicle, its hardware and software architecture including the process modeling and the control law used. Simulation results presented are based onthe AUV mathematical model.

基于 DCT(离散余弦变换 )域的信息隐藏算法是目前应用最广的变换域算法 ,此类算法的最大不足是嵌信息量小。通过分析 DCT域隐藏算法隐藏容量少的原因 ,提出了一种大容量的 DCT域信息隐藏算法。算法首先对载体图像进行频谱均匀化处理 ,然后对图像进行全局 DCT变换 ,并将隐藏信息嵌入到载体图像的低频 DCT系数上 ,信息嵌入采用分段量化的方法实现 ,提取隐藏信息时不需要原始载体图像。实验结果表明 ,该算法的嵌入容量大 ,不可感知性好。(Based on DCT (discrete cosine transform) domain information hiding algorithm is the most widely used transform domain algorithms, the largest of these algorithms is the lack of a small amount of information embedded. Hiding Algorithm for DCT domain by analyzing the hidden reasons for the low capacity, a large capacity of information hiding algorithm for DCT domain. Firstly, the spectrum of the carrier image homogenization, and then the image is a global DCT transformation, and hidden information embedded into the image of the low-frequency DCT coefficients, the information embedded in the methods used to achieve sub-quantization, extract hidden information without the original Vector image. Experimental results show that the algorithm embedding capacity, can not be perceived good.)
