Simulation of Scour at Bridge Supports

open access: yesGrađevinar, 2020
Groups of piers are used on bridges to minimise scour around bridge supports. The prediction of scour around piers due to interaction of vortices around bridge piers is more complex compared to scour prediction around a single pier.

Rate Bounds on SSIM Index of Quantized Images [PDF]

open access: yesIEEE Transactions on Image Processing, 2008
In this paper, we derive bounds on the structural similarity (SSIM) index as a function of quantization rate for fixed-rate uniform quantization of image discrete cosine transform (DCT) coefficients under the high-rate assumption. The space domain SSIM index is first expressed in terms of the DCT coefficients of the space domain vectors.
