This work is aimed to develop the key algorithms used in medical robots, which can detect alcohol use disorder from structural magnetic resonance imaging of brains. We enrolled 30 alcoholic participants and 30 nonalcoholic participants. In the algorithm stage, we suggested to use Hu moment invariant to extract global features, and use single-hidden layer neural-network as the classifier. Afterwards,...
It is of enormous significance to detect abnormal brains automatically. This paper develops an efficient pathological brain detection system based on the artificial intelligence method. We first extract brain edges by a Canny edge detector. Next, we estimated the fractal dimension using box counting method with grid sizes of 1, 2, 4, 8, and 16, respectively. Afterward, we employed the single-hidden...
The PID control as a popularly control method that is used in the control system, this control method is still adopted in many practical applications of the process currently. The paper mainly discusses the classical PID tuning methods, and on the basis of the method, which achieve a small unmanned helicopter longitudinal PID control parameters optimization by introducing the idea of genetic algorithm...
Two problems will be met with while directly using simple genetic algorithm to solve image interpolation: one is how many bits are needed for difference-chromosome coding. Setting it too large will increase implementation spending while making it too small will evolve into local minimum. The other is premature, if some individuals are most dominant in current population, they will emphasize their...
An adaptive resource allocation scheme for QoS oriented OFDMA system, which schedules two different utility functions for the Real-time/Non Real-time traffic simultaneously, is proposed in this paper. Instead of partial consideration of uniform kinds of QoS, we introduce an updating ratio factor to schedule users of heterogeneous traffic. Due to the complex optimization objective, the general convex...
