| 1 | Dynamics and Predictive Control of Gas Phase Propylene Polymerization in Fluidized Bed Reactors显示文摘A two-phase dynamic model,describing gas phase propylene polymerization in a fluidized bed reactor,was used to explore the dynamic behavior and process control of the polypropylene production rate and reactor temperature.The open loop analysis revealed the nonlinear behavior of the polypropylene fluidized bed reactor,justifying the use of an advanced control algorithm for efficient control of the process variables.In this case,a centralized model predictive control(MPC) technique was implemented to control the polypropylene production rate and reactor temperature by manipulating the catalyst feed rate and cooling water flow rate respectively.The corresponding MPC controller was able to track changes in the setpoint smoothly for the reactor temperature and production rate while the setpoint tracking of the conventional proportional-integral(PI) controller was oscillatory with overshoots and obvious interaction between the reactor temperature and production rate loops.The MPC was able to produce controller moves which not only were well within the specified input constraints for both control variables,but also non-aggressive and sufficiently smooth for practical implementations.Furthermore,the closed loop dynamic simulations indicated that the speed of rejecting the process disturbances for the MPC controller were also acceptable for both controlled variables. | Ahmad Shamiri Mohamed azlan Hussain Farouq sabri Mjalli Navid Mostoufi Seyedahmad Hajimolana~ | 2013 | Chinese Journal of Chemical Engineering2013，21，9： | 4 |

| 10 | Emerging Trends in Social Networking Systems and Generation Gap with Neutrosophic Crisp Soft Mapping显示文摘This paper aims to introduce the novel concept of neutrosophic crisp soft set(NCSS),including various types of neutrosophic crisp soft sets(NCSSs)and their fundamental operations.We define NCS-mapping and its inverse NCS-mapping between two NCS-classes.We develop a robust mathematical modeling with the help of NCS-mapping to analyze the emerging trends in social networking systems(SNSs)for our various generations.We investigate the advantages,disadvantages,and natural aspects of SNSs for five generations.With the changing of the generations,it is analyzed that emerging trends and the benefits of SNSs are increasing day by day.The suggested modeling with NCS-mapping is applicable in solving various decision-making problems. | Muhammad Riaz Masooma Raza Hashmi Faruk Karaaslan Aslıhan Sezgin Mohammed M.Ali Al Shamiri Mohammed M.Khalaf | 2023 | Computer Modeling in Engineering & Sciences2023，，8： | 0 |
