An improved analytic model predictive control method is proposed to deal with a class of bounded uncertain nonlinear systems. Firstly, invoking the standard results from the Moore-Penrose inverse of matrix, the unmatched problem which exists commonly in input and output dimensions of systems is solved. Secondly, the improved analytic model predictive control method is bounded and the control law can...
Sickbed arrangement is an important part of daily management in the hospital. Since the service time for different type of patients varies, the queuing system here, with multi-random input flow, can not be solved accurately by using classical queuing theory. Based on the analysis of patient information, we apply the simulation method into the sickbed arrangement system, and take the average waiting...
We propose two new analytical polarization ratio (PR) models based on the RADARSAT-2 Quad-Polarization (HH+VV+HV+VH) observations over the ocean. One is a function of incidence angle only and the other has additional dependence on wind speed. Comparisons are presented with theoretical and empirical PR models from the literature. The new PR model with wind speed and incidence angle dependence is shown...
Through analyzing the simulation process of the brake test-bed, using a single-loop and a double-loop control model, this paper proposes that regarding the drive current as the control point, and on this basis, establishing a non-linear control model based on single neuron self-adaptivity. Then, this paper analysis these models using computer simulation. At last, the results shows that under the self-adaptive...
By analyzing the factors which have impact on how the hospital arrange its sickbeds, this paper gives a evaluation index system about arranging the sickbeds and a evaluation model that based on the overall satisfaction of the patients and the hospital. From the perspective of patients, we consider their time, cost and the therapeutic effect, while from the viewpoint of the hospital, the analysis incorporates...
The nurturing of innovative talent is the basis of a national increase scientific and technological innovation. How to cultivate talents with innovative consciousness and innovative abilities is the major concern of Chinese higher education. Based on in-depth analysis of mathematical modeling training and contest in this paper, we came to the conclusion that mathematical modeling training and contest...
Convenient, rapid, efficient and anonymous characteristic of P2P technology, enables P2P network gathering enormous users very quickly, and P2P traffic has occupied 60~80% bandwidth of Internet. Such giant traffic has formed a threat to the service quality of other Internet application and the security of Internet itself. However, most study about P2P traffic focuses on traffic monitoring and characteristic...
