Model Reduction via Reducibility Matrix

引用

Journal of Donghua University(English Edition) 2006年第6期23卷 110-112,124页

作者： Musa Abdalla othman alsmadi Faculty of Engineering and Technology University of Jordan Amman Jordan

In this work, a new model reduction technique is introduced. The proposed technique is derived using the matrix reducibility concept. The eigenvalues of the reduced model are preserved; that is, the reduced model eigenvalues are a subset of the full order model eigenvalues. This preservation of the eigenvalues makes the mathematical model closer to the physical model. Finally, the outcomes of this method are fully illustrated using simulations of two numeric

Image Encryption Scheme Based on Filter Bank and Lifting

引用

International Journal of Communications, Network and System Sciences 2014年第1期7卷 43-52页

作者： Saleh Saraireh Yazeed Al-Sbou Ja’afer Al-Saraireh othman alsmadi Department of Communications and Electronic Engineering Philadelphia University Amman Jordan Department of Computer Engineering Mu’tah University Karak Jordan Department of Computer Science Applied Science University Amman Jordan Department of Electrical Engineering The University of Jordan Amman Jordan

In this paper, the quality of image encryption using filter bank with lifting scheme has been studied and evaluated. Many extensive techniques have been applied to examine the security of the image encryption using the filter bank cipher with one or two rounds. To analyze and evaluate the proposed scheme, many parameters have been employed, such as, histogram analysis, correlation coefficient, global entropy, block entropy, avalanche effect, number of pixel change rate (NPCR), unified average change intensity (UACI), compression friendliness, exhaustive key analysis, and key sensitivity test. The simulation results showed that, the quality of the image encryption passes all these tests. Moreover, it reaches or excels the current state-of-the-arts. So that, the proposed image encryption process produces random-like output from the statistical point of views.
