Computer aided detection and diagnosis system (CAD) is designed to improve the efficiency and quality of medical diagnosis. The existing CAD system tries to realize a diagnosis process in an automatic way to replace the doctor’s diagnosis work completely, but it is difficult to capture the doctor’s detection and diagnosis needs and goals accurately due to lack of doctor’s experience. Thus, the accuracy...
Community detection is one of the most important ways that reflect the structure and mechanism beneath the social network. The overlapping communities are more in line with the reality of social network. In the society, the phenomenon of some members shared membership of different communities reflects as overlapping communities in the network. Facing big data network, it is a challenging and computationally...
Smart grid is built by the combination of information technology and electric technology based on traditional power grid, and achieves the interaction between power generation and power utilization. However, new security issues appears together with the new cyber-physical power system, and false data injection is one of the attack means, which is impressive for it's difficult from being detected....
In order to provide uninterrupted services to the cloud clients from cloud vendors with finite resources, it is important to get as more computing and storage resources as possible and at the same time achieve network or computing load balance. In this study, we focus on the computing resource allocation involving with the management of processing power, network transmission and storage resource....
The density functional (DFT) method with the hybrid B3LYP exchange-correlation functional was proposed to study the intermolecular interactions between template and functional monomers at the prepolymerisation step. In the present work, 4-nitrotoluene (PNT) was chosen as the template. Six widely used functional monomers, methacrylic acid (MAA), acrylamide, 2-vinylpyridine, 4-vinylpyridine, methacrylamide...
A method to simulate the dynamics of public opinion formation with pheromone is proposed. It is assumed that an individual would sense and deposit pheromone during its opinion formation, and it changes and updates opinion basing on the transition probability determined by the distribution of pheromone. Using the proposed model, simulations with several sets of parameters are carried out. The results...
According to the design requirement of UAV (the unmanned aircraft vehicle), the models of threat, UAV's dynamics, guidance and trajectory planning are established. Trajectory planning adopts genetic algorithms (GAs) and genetic coding uses "distance, corner" program. Through simulating by Matlab/Simlink software, the result proves the trajectory planning according with dynamics, characteristic.
In this paper, awareness and situation ontology model is presented to process awareness and learning situations in E-Learning environment. By this model, knowledge domain, awareness information and learning situations can be described reasonably and efficiently. In addition, reasoning rules for awareness and situation are given in this model. According to these reasoning rules, the learnerpsilas awareness...
