2. Combining and Steganography of 3-D Face Textures

M. Moradi; M.R. Sadeghi

Volume 5, Issue 2 , Summer and Autumn 2017, Pages 93-100

Abstract
  One of the serious issues in communication between people is hiding information from the others, and the best way for this, is to deceive them. Since nowadays face images are mostly used in three dimensional format, in this paper we are going to steganography 3-D face images and detecting which by curious ...  Read More

3. Design of a Novel Framework to Control Nonlinear Affine Systems Based on Fast Terminal Sliding-Mode Controller

M. Keshavarz; M.H. Shafiei

Volume 5, Issue 2 , Summer and Autumn 2017, Pages 101-108

Abstract
  In this paper, a novel approach for finite-time stabilization of uncertain affine systems is proposed. In the proposed approach, a fast terminal sliding mode (FTSM) controller is designed, based on the input-output feedback linearization of the nonlinear system with considering its internal dynamics. ...  Read More

8. Research on Color Watermarking Algorithm Based on RDWT-SVD

Y. Han; X. Cui; Y. Zhang; T. Xu

Volume 5, Issue 2 , Summer and Autumn 2017, Pages 149-156

Abstract
  In this paper, a color image watermarking algorithm based on Redundant Discrete Wavelet Transform (RDWT) and Singular Value Decomposition (SVD) is proposed. The new algorithm selects blue component of a color image to carry the watermark information since the Human Visual System (HVS) is least sensitive ...  Read More

10. Alleviating the Small-Signal Oscillations of the SMIB Power System with the TLBO–FPSS and SSSC Robust Controller

H. Shayeghi; A. Ahmadpour; E. Mokaramian

Volume 5, Issue 2 , Summer and Autumn 2017, Pages 163-170

Abstract
  Power systems are subjected to small–signal oscillations that can be caused by sudden change in the value of large loads. To avoid the dangers of these oscillations, the Power System Stabilizers (PSSs) are used. When the PSSs can not be effective enough, installation of the Thyristor–based ...  Read More
