Research ArticleOpen accessAll words, across the recordTesting Image Encryption by Output Feedback (OFB)Yas A. AlsultannyWhen it is necessary to securely transmit data in open networks, the encryption must be performed. Most of the cryptographic algorithms were mainly developed for text data. Unfortunately, algorithms those are good for textual data might not suitable for image. The OFB mode of encryption implemented to test five images of different resources, by using three combinations (schemes): a combination … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,193 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordIMAGE COMPRESSION BASED ON SVD AND MPQ-BTCNidhal K. El Abbadi, Adil Al Rammahi, Dheiaa Shakir Redha, Mohammed Abdul-HameedIn this study we will provide a new way of images compression based on two mathematic concepts, these two concepts are Singular Value Decomposition (SVD) and Block Truncation Coding. The input image either is in JPEG format or in BMP format and the current way suitable for both color and gray scale images. The input image will be compressed first … …Journal of Computer Science, Vol. 10, Issue 10 · 30 Jun 2014 · 6,954 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCompressive and Shear Analysis of Rubber Block Under Large StrainK. Sridharan, R. SivaramakrishnanThe Elastomeric materials have found use in a wide range of applications, including hoses, tires, gaskets, seals, vibration isolators, bearings and dock fenders. The analysis of rubber blocks for its compression and shear behavior has been carried out using the imaging techniques. The dynamic stressing and its associated change in shape of the rubber blocks during large compression are very … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 18 Jun 2013 · 6,740 accessesView PDF Cite
