The multipath propagation in the cellular nets can cause large fluctuations of the base stations' (BSs) RSS which detected by the mobile stations (MSs).The movement of mobile stations and the changes of environment will aggravate the fluctuations of RSS. There is a possibility that RSS values appear outliers during the process from its examination by mobile stations to its transfer to the positioning...
With the development of the Rough Sets and Neural Network, dynamic prediction research on financial crisis has become as a developing trend. Based on this situation, this paper makes use of the Rough Sets' attribute reduction technique to reduce the financial index firstly, then imposes the Neural Network to train network so as to establish financial crisis alarming model to drop out enterprise's...
A vision based multiple-user small arms training simulation system is proposed for small arms training. The proposed system allows 16 users to interactive with the scene displayed on a projection screen size of 5.33m × 3m. Infrared tracking technology and the theory of projective transformation are introduced. 3 groups of infrared markers are used and an infrared marker identification algorithm is...
The pre-diagnosis to type 2 diabetes, and the effective prophylaxis and treatment of its complication is to be worthy paying attention to. So an intelligent diagnosis based on quantum particle swarm optimization (QPSO) algorithm and weighted least squares support vector machines (WLS-SVM) is presented, which can overcome the disadvantage of large sample data, slow model-building and rather large deviation...
