输水管线阀门操作水流稳定时间研究

输水管线在运行时,有时需要进行流量调节,常用的调节手段是阀门操作。大口径的输水管线为防止产生破坏性的水锤,常采用分级逐步对阀门操作,在两次阀门操作之间,需等待水力条件稳定后再进行下一次的阀门操作,因此两次阀门操作之间的水流稳定时间是重要的影响因素。通过对达西公式的分析,确定阀门操作水流稳定时间,在水流稳定后再进行下一步的阀门动作,可保证水力状态不叠加,不会产生因水锤致使管线爆管的事故。

Deadlock control of autonomous vehicle storage and retrieval systems via coloured timed Petri nets and digraph tools

This paper addresses the deadlock control problem for the autonomous vehicle storage and retrieval system (AVS/RS). For an AVS/RS with several autonomous vehicles running in bi-direction, deadlock control is one of the key issues in the implementation of AVS/RS. The cycle-deadlock is the main type of deadlock in AVS/RS. In the paper, the dynamic model of AVS/RS is investigated by using coloured timed Petri nets (CTPN). Based on the CTPN model, a route digraph is built to detect cycle-deadlock in AVS/RS with digraph tools; the necessary and sufficient conditions of deadlock-free are established. Moreover deadlock-free control policies are proposed, the critical state in deadlock free is also identified and FCFS policy is applied to solve it. Finally, a case study is given to validate the policies.     

Design of a timed and controlled release osmotic pump system of atenolol

The objective of the article was to design a novel timed and controlled release osmotic pump (TCOP) containing atenolol as an active pharmaceutical ingredient and compare with a bilayer-core osmotic pump (BCOP) of atenolol. Different from BCOP, a modulating barrier was added to delay the drug release and obtain desired lag time (T_lag). The influences of the amount of pore-forming agent and modulating barrier, coating weight gain on the lag time (T_lag) and drug release rate (R_t) of TCOP were investigated. The central composite design-response surface methodology (RSM) was applied to optimize the formulation. Rhodamine B was added to modulating barrier to determine the release process of modulating barrier. A method used to correct the release profiles with a certain lag time by ΔT_lag and interpolating was applied to compare TCOP with BCOP. T_lag was directly proportional to the amount of modulating barrier and coating weight gain, but inversely related to the amount of pore forming agent, which were contrary to the effects on R_t. The optimal formulation including 60?mg PEO WSR N80, 3?g PEG 4000 and 6% coating weight gain could obtain a 3.59-h T_lag. According to the release of Rhodamine B, the modulating barrier was completely pushed out at ～5.0?h, longer than 3.59?h, therefore, atenolol along with remaining modulating barrier was released together between 3.59 and 5.0?h. By comparing with BCOP, the release profiles subtracting the part of lag time had no significant difference, yet R_t of TCOP presented a slight decrease.

Investigation of the phase formation wave in the model of solid state amorphization

Computation results of the model of solid state amorphization (SSA) based on a general approach to non-equilibrium phase transitions are reported. The model takes into account the mutual interaction of the structural elements of the amorphous phase via a deformation field. For the experimental parameters, corresponding to semiconductors undergoing amorphization by high-pressure treatment, a family of self-sustaining autowave solutions in the form of a traveling front, a traveling pulse and a series of pulses associated with the traveling front was obtained. The relation of these solutions with the expected morphology of amorphous samples produced by SSA is discussed.

Maximum-likelihood mixture factor analysis model and its application for process monitoring

In the present paper, a mixture form of the factor analysis model is developed under the maximum-likelihood framework. In this new model structure, different noise levels of process variables have been considered. Afterward, the developed mixture factor analysis model is utilized for process monitoring. To enhance the monitoring performance, a soft combination strategy is then proposed to integrate different local monitoring results into a single monitoring chart, which is based on the Bayesian inference method. To test the modeling and monitoring performance of the proposed mixture factor analysis method, a numerical example and the Tennessee Eastman (TE) benchmark case studies are provided.
