6.1 Literature review matrix Taha E. et al (2015) evaluated Diclofenac Sodium (DS) matrix tablets prepared by direct compression method under different compression forces using ethyl cellulose as matrix forming material. The produced tablets were characterized for hardness, friability, drug content, weight variations and in vitro drug release. Incompatibility study carried out using DSC FT-IR s...

The design and manufacture of tablets is a challenging process due to the complex interrelationships between raw material properties, manufacturing settings tablet properties. An important factor in formulation fact that properties drive disintegration dissolution performance final drug product. This study aimed identify mechanisms which control for 16 different immediate-release placebo formul...

geometric and material nonlinear behavior of slender webs in i-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. in addition, the effects of flange and web slenderness rati...

In H.264 video compression standard, B frame bi-directional predictions and its DIRECT mode coding are included to enhance video compression efficiency. However, such tools require a complex mode decision process and result in a long computation time. Therefore, fast algorithms are crucial in implementing H.264. In this paper, to save B frame encoding time, a fast DIRECT mode prediction algorit...

Based on Side-Match Vector Quantization (SMVQ), the authors propose two schemes to embed more secret information without significantly sacrificing the compression ratio. The data transform scheme improves the embedding capacity while maintaining the same compression ratio. The direct embedding scheme improves the embedding capacity at the expense of increasing the compression ratio slightly. Ac...

Lossy image compression techniques allow arbitrarily high compression rates but at the price of poor image quality. We applied maximum likelihood difference scaling to evaluate image quality of nine images, each compressed via vector quantization to ten different levels, within two different color spaces, RGB and CIE 1976 L*a*b*. In L*a*b* space, images could be compressed on average by 32% mor...
