Xanthii Fructus (XF) has been used for treatment of allergic rhinitis (AR), but its pharmacological mechanism of action remains unclear. We aimed to explore the potential mechanism of XF in treatment of AR by using a network pharmacology approach combined with in vivo verification experiments in this study. We identified 945 AR‐related pathogenic genes, 11 active components in XF and 178 targets of...
Beer fermentation process has the characteristics of nonlinear, time varvine and pure lae. Since tradition PID control and fuzzv PID control are difficult to satisfy the control reauirements, an improved variable universe fuzzv PID control method is proposed. The variable universe fuzzv controller is improved bv adapting scale partition method. PID control, fuzzv PID control and imnroved variable...
Intelligent control has been greatly developed and theoretically researched, but it is usually limited to the off-line simulation research. In order to put advanced control algorithms into practice, using a reliable OPC (OLE for Process Control) technology to connect the field process and control equipment, and to realize the data reading in real time, the specific implementations way to achieve real-time...
The fuzzy PID controller can adapt to the change of the controlled object, so as to realizing the control requirement of chlorine flow in the chloroacetic acid reaction kettle. Theoretical analysis and MATLAB simulation results show that fuzzy self-adaptive PID control has better control performance than conventional PID control.
In addition to the traditional analog filter circuit, an intelligent filter chip MAX260 that can track signals with a certain frequency, and keep their amplitude and phase constant but attenuate signals with other frequencies as the microchip controller part's filter is added after the pre-processing circuit. Combining MAX260 and digital filtering arithmetic, the anti-disturbance of the conditioning...
As the enrollment expansion of Independent College, the demand for teachers has increased dramatically. Taking the analysis of the characters of the students, cultivation purpose and the teaching faculty construction as the point of departure, this paper focuses on analyzing the problem existed in the teaching team construction in Independent College, and some improvement measures are proposed for...
According to the characteristics of control special and the society's demand, the reform idea is proposed based on the combination of computer and the control class curriculum group. Based on the reform principle, it carries on the exploration and practice in the teaching goal, the course content, the educational model, the practice teaching and so on. From the practice result it shows that it not...
According to the characters of relatively weak cultural foundation though the overall quality relatively high of independent college students, the “Automatic Control Theory” teaching reform ideas and methods are proposed combining with long-term teaching experience and the application of network and information technology. The curriculum reform includes many aspects such as teaching content, teaching...
Some problems of traditional experimental teaching in colleges are analyzed in this paper, then a three layers experimental system is put forward based on reforming and innovating the mode of talent training as fundamentality and development and reconstruction of new experimental equipment and experimental platform. In practice, focusing on the connection between knowledge, creating a new context,...
Coagulant dosing process is an important part in water treatment plan, it directly affects the water quality and operating costs of production. It is very difficult to set up its mathematical model accurately basing on its reactive mechanism at present. Factors that affect the coagulation effect are analyzed in this paper, then a BP neural network prediction model of coagulant dosage is established...

At the end of the paper, it gives the specific content of high quality teaching...
Crystallization process control system is a complex system with time variable parameters. Temperature rising rate requirement in each running stage is deferent. In this paper it is introduced a nonlinear scaling factors fuzzy control scheme, which can tune and optimize the parameters of scaling factors based on genetic algorithm(GA). From the simulation result, it shows that control system has the...
The output of ultrasonic object-location meter changes with the environmental temperature. In order to eliminate such a situation, a new information fusion algorithm based on neural network is presented. A virtual ultrasonic object-location measurement temperature compensation system is realized based on a method of the hybrid programming of MATLAB and LabVIEW with MATLAB Script node. A improved BP...
