This paper aims to investigate the problem of low-dose computed tomography (CT) reconstruction with prior image constraints using the compressed sensing (CS) theorem. The CS theorem states that images can be reconstructed from under-sampled data in an adequate or transfer domain without introducing noticeable artifacts by solving a convex optimization problem if the source signals are sparse. To describe...
As Command, Control, Communications, Computer, Intelligence, Reconnaissance, and Surveillance (C4ISR) systems are used more widely in the Army, the training on it become more important. To provide a realistic Environment for training, we adopt the Simulation-based Training Support Environment (S-TSE) for promoting training with C4ISR systems. The development of Interoperability of S-TSE with C4ISR...
In the evaluation process of Military communication network effectiveness (MCNE), the evaluation data mainly come from expert judgments, simulation results and test bed data, and these data cannot be directly used to evaluate MCNE because these three kinds of data are very different in form and in attribute. This research proposed a novel method which synthesizes expert judgments, simulation results,...
A novel nonlinear model is proposed for nonlinear system blind identification with infinite memory. This model is a generalization and combination of both ARMA model and Volterra-Hammestein (NMA-Hammestein) model. In the process of blind identification, two steps are involved. First, we focused on the left part (AR) of model form,which could be identified by using the generalized BBR formula and MYW(modified...
The Influence Diagrams (IDs) is a kind of Probabilistic Belief Networks for graphic modeling. The usage of IDs can improve the communication among field experts, modelers, and decisionmakers, by showing the issue frame from a high-level point of view. But with the size and scope increasing of the complex issue descibed, the IDs model evaluation is more and more difficult. Moreover, the appearances...
Influence Diagrams (IDs) are not only used to display a graphical representation of the qualitative structure of models, but also to improve the communication among subject-matter experts, analyzers, and decisionmakers, by showing the frame of issue discussed from a high-level point of view. This thesis provided a curt overview of IDs and its evaluating, then introduced the extended Time-Sliced IDs...
Heart rate variability (HRV) is a measure of variation in the heart rate. Over the last 25 years, HRV analysis has became utilized more often as a non-invasive research and clinical tool for indirectly investigating both cardiac and autonomic nervous system (ANS) functions in health and disease. In our experiment, 22 healthy subjects and four testing rhythm patterns are studied. How the three musical-rhythmic...
