Dialysis adequacy shows validity of dialysis schemes in renal failure patients, which is relative to state of patients. An accurate evaluation for dialysis adequacy is very important. Aiming at the clinic actual situation, an evaluation index system of dialysis adequacy is proposed in this paper. In view of subjectivity in the determination of weights in the traditional model, entropy theory is used...
This paper proposes an image enhancement algorithm based on fuzzy theory. The average of all adjacent points is as enhancement threshold and affiliation of each point is obtained by counting the average. Then, enhancement images are obtained with inverse transformation. Experiments have proved that contrast of vein and background is enhanced and effect of image segmentation and extraction is improved...
In this paper, based on the principle of agent technology, the architecture of Internet intelligent tutoring system (IITS) based on MAS (multi-agent system) and data-mining technology is designed, and a model of data-mining agent which can provide individual tutoring service is constructed, the applications of data-mining technology on IITS is discussed. These will guide to develop the IITS with high...
The problem of optimal disturbance rejection control (ODRC) with zero steady-state error to sinusoidal disturbances for stochastic discrete-time systems is considered. Based on the internal model principle, external sinusoidal disturbance is compensated by constructing a disturbance compensator. Then, an optimal linear quadratic Gaussian (LQG) controller with an infinite-time horizon cost functional...
The Graphplan planner has enjoyed considerable success as a planning algorithm for classical planning problems. However, it is argued that this framework is too rigid to capture the full subtlety of many real problems. Hence, a new flexible planning problem is defined and flexible planning method emerges as the times require. This paper just makes research on flexible Graphplan and applies a novel...
Since Graphplan was proposed, intelligent planning has become a research focus in AI. This paper provides a new algorithm that extends Least Committed Graphplan to handling conditional effects. Different from the previous work on it, we employ the sub-mutex relations between action components, which makes the construction of planning graph much faster. In addition, we distinguish brotherhood components...
At present, intelligent planning in the Graphplan framework is a focus of artificial intelligence. Creating or Destroying Objects Planning (CDOP) is a kind of unsolved but very important problems of this field. In this paper, we make research on such planning problems, divide them into two types and give intensive analysis respectively. We first bring forward the idea of transforming objects into...
