A Secure Image Steganography Using Shark Smell Optimization and Edge Detection Technique
Get PDFThe stegangraphic system supply premium secrecy and ability of conserving the mystery information from gaining stalked or cracked. The suggested method consists of three phases which are edge detection, embedding and extraction. This paper concentrated on three basic and significant parts which are payload, quality, and security also introduces a new steganography method by using edge detection method and shark smell optimization to effectively hide data with in images. Firstly, to promote the hiding ability and to realize altitude standard of secrecy the mystery message is separated into four parts and the cover image is masked and also divided into four sections, then the edge detection algorithm and shark smell optimization is performed on each section respectively. Edge prospectors were utilized to produce edge pixels in every section to hide mystery message and attain the best payload. To increase security, the shark smell optimization is used to select the best pixels among edge pixels based on its nature in motion, then reflect these pixels above original carrier media. Finally the mystery message bits are hidden in the selected edge pixels by using lest significant bit technique. The experimental outcomes appreciated utilizing several image fitness appreciation fashion, it displays best hiding ability, achieve higher image quality with least standard of deformation and provide altitude standard of secrecy, also the results shows that the suggested method exceeds previous approaches in idioms of the PSNSR, MSE also demonstrate that the mystery information cannot be retrieved of the stego image without realizing the algorithms and the values of parameters that are used in hidden proces
Application of Principal Component Analysis for Steel Material Components
Get PDFIn this research, we made use of the principal component analysis (PCA) technique, which is a multivariate statistical method that transforms a fixed number of correlated variables into a fixed number of orthogonal, uncorrelated axes known as principal components by making use of orthogonal transformation. In other words, the PCA technique converts correlated variables into uncorrelated axes. To minimize the dimensionality of a data set that included a large range of connected variables while yet keeping as much variance within the data set as possible, we employed a method called principal component analysis (PCA). This allowed us to analyze eleven steel components. This is accomplished by reworking the unique variables into a brand new set of uncorrelated variables known as principal components (PC). The principal components are ordered in such a way that they preserve the majority of the variation that is found in all of the unique variables. This is done by reworking the unique variables into a brand new set of uncorrelated variables called principal components (PC). We are able to come to the conclusion that the five principal components that collectively account for approximately sixty-seven percent of the variance in all of the data are the best principal components because this percentage represents the best principal aspect of all of the 11 principal components

Get PDFThe aim: This study was designed to explore the potential hepatoprotective effects of Nasturtium officinale and Allium polyanthum plant extracts against CCl4-induced hepatic injury in rat model.
Methods: Thirty healthy male albino rats were equally divided into 5 groups: Normal control (NC), Positive control (Pos-C), Nasturtium officinale extract (NOE), Allium polyanthum extract (APE), and NOE + APE. The animals were fed with a standard diet and distilled water ad libitum. Except for NC, all other groups were exposed to CCl4 at every 72 hours for 3 weeks to induce hepatic damage. Corresponding treatments were established to the respective groups during study period. Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Alkaline phosphatase (ALP), Total serum bilirubin (TSB), Total protein (TP), Albumin (ALB) and malondialdehyde (MDA) were measured in serum at the end of the study. Histopathological analysis of the liver sections was also determined.
Results: CCl4-treated rats were showed significant increase (p < 0.05) in the levels of serum enzyme activities (AST, ALT, & ALP), TSB and MDA; reflecting the hepatocellular damage caused by CCl4 compared with NC rats, whereas the levels of TP and ALB were decreased. Furthermore, the histological examination of liver tissues showed that CCl4 triggered several histological variations in the liver tissues. Treatments of NOE and APE along with CCl4 for 3 weeks significantly (P<0.05) improved the CCl4-induced changes in serum biochemical parameters and liver histology as compared to Pos-C rats indicating the protection of hepatic cells.
Conclusion: Treatments of NOE and APE either in separate or in combination have shown significant improvement in CCl4-induced hepatopathy in experimental rats as evidenced by observed results in serum and hepatic histopathological examination
