Analysis of smart crack detection methodologies in various structures

This paper describes a comprehensive review of various technical papers in the domain of crack detection in Beam-Like Structure. Sensibility analysis of experimentally measured frequencies as a criterion for crack detection has been extensively used in the last decades due to its simplicity. However determination of crack parameters (like depth and location) is not straight forward. The various techniques discussed on...

Deoxyribonucleic acid (DNA) as a hypothetical information hiding medium: DNA mimics basic information security protocol

While the computational capabilities of deoxyribonucleic acid (DNA) are now fairly known, with the building of DNA computers which utilize DNA and other sub-cellular molecules as input and output, little seems to have been investigated on the information security properties of DNA in computer science and information technology terms. The author investigated DNA as a hypothetical information hiding molecule, which...

Determination of oscillator strength of caffeine and caffeine in tea leaves by the integrated absorption coefficient technique at two different temperatures

In this paper, oscillator strength of caffeine in dichloromethane, water, chloroform, and ethyl acetate were calculated in the wave number range of 32, 000 to 41,000cm-1. It was found that oscillator strength of caffeine in dichloromethane, water, chloroform, and ethyl acetate were 0.230 ± 0.001, 0.170 ± 0.0003, 0.114 ± 0.001, 0.150 ± 0.001 respectively. Caffeine content of real tea leaves...

Statistical digital image stabilization

In this paper, an efficient algorithm for the statistical digital Image stabilization (SDIS) is proposed to reduce the computational cost of block matching algorithm, for local motion estimation. This method is based on calculation of statistical functions, mean and variance of pixels in each block; four blocks are used in each frame. By using the statistical functions, the best block is selected then the local motion...
