The Single First Order Equation,e of two independent variables, but it will be made clear that the theory can be extended immediately to any number of variables. We consider then equations of the form . where we have used the notation u. = p, u. = q. A solution z = u(x, y), when interpreted as a surface in three dimensional space,

Fritz Johnies, typical cities are chosen as the research object. According to urban road information, regional population distribution, residents’ trip characteristics, the as-built charging facilities and other information, the charging demand model of electric vehicles is constructed, and the optimized layo

Fritz Johnily affected by light. A surface defect detection model based on improved UNet-based neural network, surface defect UNet (S-UNet), is proposed to address the limitations of traditional detection algorithms in surface defect detection, as well as the problems of low accuracy, low precision, and cumbe

Fritz John consider characteristics, such as texture and luminous, of the host image, thus not sufficiently balance the trade-off between the invisibility and robustness. Aiming at this issue, we propose a scheme that can dynamically change the embedding strength and location according to the image features.

Fritz Johnristics, the as-built charging facilities and other information, the charging demand model of electric vehicles is constructed, and the optimized layout of public charging infrastructure in typical cities is developed in combination with traffic flow model, which provide an effective solution for rational allocation of urban charging systems.

Fritz Johnt image is divided into non-overlapping blocks and performed singular value decomposition (SVD). The experimental results implicate that the scheme achieves satisfying imperceptibility and is superior to the similar robust watermarking schemes under common attacks and geometric attacks.
