Ultrasound (US) examination plays a important role in diagnosis process. The goal is to improve the efficiency of US in West China Hospital of Sichuan University. This paper presents results from the use of sub-period appointment. At first, process mapping was used to identify the flow of examination and the bottleneck of it. Then the flow was modeled by the latest simulation platform-simio. Different...
In recent years, few Chinese hospitals introduced operation mode named day surgery, This paper concerns that the introduction of day surgery has an impact on patients, we put forward a question whether carrying out day surgery will reduce waiting time for admission. This paper put forward a hypothesis: carrying out day surgery reduces waiting time for admission. We collect datum related to Laparoscopic...
This paper studies off-line control and on-line control based on Adaptive Dynamical Programming and proposes an optimal adaptive algorithm with the combination of off-line and on-line training; The method using off-line value iteration algorithm gets off-line opitical controller, then using on-line policy iteration algorithm of Q learning improves the off-line opitical controller. Simulation results...
The success of ecological recovery depends on the plants selection. The thirty-one typical sample plots were selected along Wushen road at different elevation in this article. The trees, shrubs, and grasses of the thirty-one typical sample plots were investigated in winter and spring detailedly. And the main plant kinds were obtained. The composition of plants and common plants were analyzed at different...
In this paper, a numerical method (termed, E47 algorithm) based on linear variational inequalities (LVI) is presented and investigated to solve quadratic programming (QP) problems which are simultaneously subject to linear equality, inequality and bound constraints. Note that such constrained QP problems can be equivalent to linear variational inequalities and then to piecewise-linear projection equations...
This paper discussed the design of the test model of leakage monitoring based on the distributed optical fiber temperature sensing technology, including the choice of filling and test condition. This model test can better simulate the practicable leakage of dam and canal. Through analyzing the influence level of key factors, four main factors including initial temperature, heating power, filling type...
