Copy-paste forgery is a very common type of forgery in JPEG images. The tampered patch has always suffered from JPEG compression twice with inconsistent block segmentation. This phenomenon in JPEG image forgeries is called the shifted double JPEG (SD-JPEG) compression. Detection of SD-JPEG compressed blocks can make crucial contribution to detect and locate the tampered region. However, the exi...

Although it has good compressive behavior, adobe masonry is classified as a quasi-brittle material mainly due to its relative low tensile strength and softening behavior after the peak strength. The plus high variability in mechanical properties, makes difficult evaluate performance of entire buildings. For such purpose, development reliable computationally efficient numerical approaches requir...

We present a superfast divide-and-conquer method for finding all the eigenvalues as well as all the eigenvectors (in a structured form) of a class of symmetric matrices with off-diagonal ranks or numerical ranks bounded by r, as well as the approximation accuracy of the eigenvalues due to off-diagonal compression. More specifically, the complexity is O(r2n logn) + O(rn log n), where n is the or...

In this paper, we propose a new protocol for data compression task, blind quantum compression, with finite local approximations. The rate of is susceptible to approximations even when the are diminutive. This instability originates from sensitivity structure states against approximations, which makes analysis in presence intractable. constructed that takes advantage reduce substantially. Our sh...

frps (fiber reinforced polymer) possess many favorable characteristics suitable and applicable for construction industry when compared with steel reinforcement. there are new ideas to use frps as longitudinal or transverse reinforcement for new concrete elements particularly for bridge decks or beams. although high tensile strength of frp is main characteristic for applications at both areas, i...

In practical video storage and distribution systems, video sequences are stored and transmitted in a compressed format. During compression, the video frame is transformed from the spatial domain into frequency domain. Therefore, video content authentication methods need to be robust to lossy compression. This paper proposes a novel semi-fragile watermarking video content authentication based on...
