In present work, a new modified particle swarm optimization (PSO) technique is utilized for model order reduction of large scale linear SISO and MIMO systems. Based on the linear descending inertia weight, this paper proposes a new modified inertia weight strategy. Since this modification gives the PSO algorithm the characteristics of rapid convergence speed and better global search ability, the proposed...
In this research, we propose a secure multi-modal biometric authentication that will have cancellable property. Cloud servers need to have the confidential information mobile and ready in case of cancellation so that the same user can authenticate or identify using the same authentication process when joining to other clouds. However, a cloud server needs to be careful transferring biometric data...
Recently, the local stereo matching algorithms based on the adaptive weighting achieve very accurate disparity maps. Compared to global matching approaches, the local algorithms offer less complexities. However, these methods are still beyond hardware ability for real-time application. In this paper, a novel linear stereo matching algorithm with constant execution time is proposed. To begin with,...
Environmental control and life support system(ECLSS) of the manned spacecraft is an important system to guarantee the safety and life support of the astronauts and the environment inside the space station. For the physicochemical regeneration type of ECLSS(PRLSS), because of its complicated physicochemical process, to analyze and evaluate the mass balance and operation performance through simulation...
The goal of salient object detection is to estimate the regions which are most likely to attract human's visual attention. As an important image preprocessing procedure to reduce the computational complexity, salient object detection is still a challenging problem in computer vision. In this paper, we proposed a salient object detection model by integrating local and global superpixel contrast at...
The approach on parallelization is studied in the paper in order to improve the calculation efficiency, calculation mode of static characteristics of the relay, and scalability of algorithms on more complex issues and larger numerical issues. For the clapper-type relay, we establish its physical and mathematical model. Then propose a modified formula of Amdahl's law to assess the effectiveness of...
The eigenvalue problem of a tapered pre-twisted orthotropic composite blade is studied using a radial basis function model. The pre-twisted orthotropic composite blade is characterized with an Euler-Bernoulli beam model. The radial basis function model is used to transform the partial differential equations of a tapered pre-twisted orthotropic composite blade into a discrete eigenvalue problem. This...
Deep Convolutional Neural Networks(DCNNs) have recently shown great performance in many high-level vision tasks, such as image classification, object detection and more recently outdoor semantic segmentation. However, the convolutional layer only process the local regions in the image, ignoring the global context information. To overcome this poor localization property of Convolutional Neural Networks(CNNs),...
In this letter, the symplectic multiresolution time-domain(MRTD) method is introduced for the analysis of waveguide. The numerical results show that stability and numerical dispersion can be significantly improved by using the symplectic integrator, as compared to the conventional MRTD. We demonstrate that with comparison to the conventional MRTD, the symplectic MRTD yields significant CPU time and...
This paper proposes a computational model along with an algorithm for a new problem in computer-aided design of systems. The new problem stems from a so-called rapid prototyping of system (RPS) technology the authors developed elsewhere before. The RPS has learned from traditional rapid prototyping technique which is in essence to construct a component from the material (liquid, sheet, etc.); but...
With the rapid development of the Web, Internet gambling has become a global problem, which causes nontrivial social impacts. Despite of its prosperity, in the major countries such as United States, Russia, and mainland China, Internet gambling is explicitly prohibited, and in the most remaining countries, Internet gambling is under strict regulations. However, there are so many websites that it is...
