Authors: Ning Yong Min , Li Ling Ling , Shi Hua , Chen Jing
Published: December 2011

In this paper, an image de-noising algorithm based on the Dual-Tree Complex Wavelet Transform (DT-CWT) is proposed, which takes the advantage of redundant coefficients transformed by DT-CWT. The model of bivariate shrinkage function is used to provide a nonlinear threshold strategy. It exploits the dependency between inter-scale parents and children coefficients to recover the original coefficients more accurate. With the shift-invariance property of DT-CWT coefficients, the algorithm prevents the Gibbs effect caused by the thresholding, which further improves the reconstructed quality. Experiment results show that the de-noised image using DT-CWT can achieve more than 1dB prior to DWT with impressive visual results.

A Novel Optimization and Control Method for Signalized Traffic Network
Authors: Chen Xiao Feng , Shi Zhong Ke
Published: December 2011

For the dynamic optimization and control problem of the signalized arterial network in urban, a dynamic traffic flow model based on multi-phase control is firstly formulated, in which the total number of the retained vehicles through the arterial during the control period is adopted as the optimization objective and the green times and offsets as the control variables. Then a hybrid optimization method based on real-coded genetic algorithm and local search technique is designed to solve the optimization problem. For examining the validity of the optimization and control method proposed, it is applied to a case study with dynamic traffic demands and a large number of simulations show that the dynamic optimization and control method proposed in this paper can work well for the signalized arterial network.

Authors: Xu Yu
Published: December 2011

Due to the rapid growth of non-linear loads in power systems, harmonic pollution is becoming more and more serious. Begin with the definition of harmonic power, the direction of power flow is analyzed from the sides of both fundamental and harmonic wave. Through a harmonic simulation circuit based on PSCAD/EMTDC, the conclusion that as a result of harmonic, harmonic-sources have their metered electric energy reduced, while non-harmonic-sources increased has been brought out. What's more, according to the result of simulation, the interactive influence of fundamental and harmonic wave on power measurement is proposed. Due to the above conclusion and the work principles of electromagnetic induction meter and electric meter, the reasons of measurement errors are found. And at the end of this paper, the development and current status of power definition which is a necessary key to the power measurement are discussed.
Nonlinear Herding Mechanism and Asset Price Evolution
Authors: Fang Yong
Published: December 2011

The present study focuses on the nonlinear herding mechanism in financial markets and provides a possible explanation for the bubble phenomenon. A market model, in which the nonlinear herding mechanism plays a role, is developed. The simulation shows that the odds of occurrence and the strength of bubbles change more intensely with herding coefficient, and are much greater under the nonlinear herding pattern than under the linear type.

Almost everyone has been in the situation where they are locked out of their house and it would be helpful if there is a way for them to lock or unlock the door without using a key. This paper explains the design of a deadbolt lock that is controlled through the phone line and can be locked or unlocked remotely from anywhere. This project consists of circuit to pick up a phone call and determine the keys pressed by the user at the other end of the telephone line as well as the software to verify an input password and ultimately control the lock. The paper details the steps it took to create the final design of the project, the problems encountered, and the final results. It also examines the estimated cost of manufacturing this product.

Published: December 2011

This paper reports on the simulation and characterization of a microelectromechanical system (MEMS) micromirror fabricated with PolyMUMPs. The overall diameter of the hexagonal micrimirror, including mirror plate and 3 supporting cantilevers fixed around, is 450um. A 3D model is built in finite element method (FEM) with COMSOL. Simulations of the elevated height of mirror plate, pull-in voltage and eigenfrequency of the micromirror are carried out. The static and dynamic performances of the fabricated micromirror are characterized by Veeco Optical Profiler and Polytek MEMS System Analyzer. The comparison between measurement and simulation exhibits good concordance. Surface topography measurement shows the elevated height and stress-induced concave deformation of mirror plate almost the same scale as demonstrated in FEM simulation. The Pull-In voltages are measured to be around 32V in current-voltage curve which is almost the same as in FEM simulation with one electrode biased. The fundamental resonant frequency is measured to be 4.3k Hz in torsional motion and 4.9k Hz in piston motion.

Published: December 2011

The recent progress in the digital multimedia technologies has offered many facilities in the transmission, reproduction and manipulation of data. However, this advance has also brought the problem such as copyright protection for content providers. Digital watermarking is one of the proposed solutions for copyright protection of multimedia. This paper proposes a blind watermarking algorithm based on fractal model in discrete wavelet domain for copyright protection. The idea of the presented scheme is to hide a binary image as a watermark with fractal parameters in wavelet domain of host image. Fractal compression technique is used to encode a gray image and fractal codes are embedded into the wavelet coefficients of the gray image according to well-connected watermark algorithm. The experimental results show that the algorithm is robust against geometric and non geometric attacks.
Simulation and Analysis of Nonlinear System Identification Using the LMS Volterra Filter
Authors: Rai Amrita , Kohli A.K.
Published: December 2011

Nonlinear system Identification based on Volterra filter are widely used for the nonlinearity identification in various application. A standard algorithm for LMS-Volterra filter for system identification simulation, tested with several convergence criteria is presented in this paper. We analyze the steady-state mean square error (MSE) convergence of the LMS algorithm when random functions are used as reference inputs. In this paper, we make a more precise analysis using the deterministic nature of the reference inputs and their time-variant correlation matrix. Simulations performed under MATLAB show remarkable differences between convergence criteria with various value of the step size. Along with that the least mean squared (LMS) adaptive filtering algorithm may experience uncontrolled parameter drift when its input signal is not persistently exciting, leading to serious consequences when implemented with finite word-length. The second order LMS Volterra filter with variable step size for system identification are analyzed and comparing the theoretical value with experimental value. Copyright © 2009 IFSA.
