This paper presents a technique of digital image watermarking using DCT wavelet transform. Use of Haar wavelet is very common in watermarking. However, here DCT wavelet transform of size 256*256 is generated using existing well known orthogonal transform DCT of dimension 128*128 and 2*2. This DCT Wavelet transform is used in combination with the orthogonal transform DCT and SVD to increase the ...

The decay of kinetic helicity is studied in numerical models of forced turbulence using either an externally imposed forcing function as an inhomogeneous term in the equations or, alternatively, a term linear in the velocity giving rise to a linear instability. The externally imposed forcing function injects energy at the largest scales, giving rise to a turbulent inertial range with nearly con...

Karl Popper discussed admirably the choice between faith and reason [Popper, 1945, Ch. 24]. He admitted that the basis of rationalism is a faith of sorts, a faith in reason. Later on his disciple William W. Bartley dissented from him [Bartley, 1962] and even called him a fideist [Radnitzky and Bartley, 1987, 205, 208, 210-11], much to his annoyance. All this caused bad blood between the two [La...

In human computation systems, humans and computers work together to solve hard problems. Many of these systems use crowdsourcing marketplaces to recruit workers. However, the task selection process of crowdsourcing workers is still unclear. We therefore outline this process and propose a structural model showing the criteria that workers use to choose tasks. The model is based on the person-job...
