This paper presents a novel image watermarking technique using Kekre’s algorithm to generate hybrid wavelet transform DKT_DCT from Kekre transform and Discrete Cosine Transform. In the proposed technique, 256x256 hybrid transform is generated using 16x16 Kekre transform and 16x16 DCT whereas, 128x128 hybrid wavelet transform is generated using 32x32 Kekre transform and 4x4 DCT matrix. Generated...

Many techniques of arthroscopic rotator cuff repair have been described. No significant differences in clinical outcomes or rerupture rates have been observed when comparing single-row with double-row methods. Not all single- and double-row repairs are the same. The details of the technique used are crucial. It has been shown that the suture-tendon interface is the weakest point of the reconstr...

In this paper, we propose a capacity scaling heuristic using a column generation and row generation technique to address the multicommodity capacitated network design problem. The capacity scaling heuristic is an approximate iterative solution method for capacitated network problems based on changing arc capacities, which depend on flow volumes on the arcs. By combining a column and row generat...

The problem of jittery and noisy image reconstruction is considered. Bispectrum-based image row Fourier magnitude and phase spectra reconstruction technique and algorithm using pre-distortions of image rows are designed and investigated. Tapering pre-distortion function of Gaussian shape introduced in each image row permits to decrease spectral leakage, obtain continuous image row phase bispect...

In this project, we had to implement a parallel solver for linear equation systems, using a technique known as Gaussian elimination (GE). As with many other algorithms for solving linear equation systems, GE is performed on the matrix representation of the system, Ax = b, where A is the coefficient matrix and b is the vector of known values. GE works by applying a set of elementary row operatio...

Can the availability of poorly-designed government insurance alter technology adoption decisions? A theoretical model of technology adoption and insurance incentive effects for a highand low-risk technology is developed and explored empirically using a unique dataset of skip-row agronomic trial data. A multivariate nonparametric resampling technique is developed, which augments the trial data w...

in in order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (rcbd) with 4 replications in saat-loui agricultural station of west azerbaijan province. in this research, the first factor (a) contained two levels 20 and 40 cm inte...
