This paper presents industrial case studies of the performance evaluation of two industrial multivariate MPC-based controllers at the Mitsubishi chemical complex in Mizushima, Japan: 1) a 6-output, 6-input Para-Xylene(PX) production process with 6 measured disturbance variables that are used for feedforward control; and 2) a multivariate MPC controller for a 6-output, 5 input poly-propylene spl...

PID controllers have become the most predominant control element for industrial process control . Programs used for industrial process control are written in many software tools but this paper focuses on MATLAB simulation . In this paper, an optimal method for tuning PID controllers for first order plus time delay systems is presented using dimensional analysis and numerical optimization techni...

Data on carbon emissions, industrial output growth, population growth and FDI inflows are used for Bangladesh, Nepal and Maldives over 1972 – 2008. Time series data on all variables are nonstationary in terms of both ADF and KPSS tests with different orders of integration. As a result, ARDL model and VECM are estimated. There are evidences of cointegrating relationship among the variables, long...

Input variable scaling is one of the most important steps in statistical modeling. However, it has not been actively investigated, and autoscaling is mostly used. This paper proposes two input variable scaling methods for improving the accuracy of soft sensors. One method statistically derives the input variable scaling factors; the other one uses spectroscopic data of a material whose content ...

Isomerization of the glucose content of high fructose corn syrup (HFCS) into fructose needs to be strictly controlled in order to obtain a balanced product for sweetness and solubility, creating a non-trival problem. This work presents an approach to modelling of a real industrial isomerization reactor by artificial neural networks (ANN) pre-processed with principal component analysis (PCA). Th...

N O T E . Charles Gilbert directed the 2002 revision and, along with Kimberly Bayard, William Cleveland, and Dixon Tranum, prepared the revised estimates of industrial production. Norman Morin and John Stevens prepared the revised estimates of capacity and capacity utilization. In late 2002, the Federal Reserve published a revision of its index of industrial production (IP) and the related meas...

In earlier research we developed a theory for predicting the reliability of conventional sequential programs based on an estimate of residual faults. This paper describes how the theory was applied to a realistic industrial example containing a known number of faults. The industrial example was implemented in a PLC application language where the program is represented by a network of logic gate...

This paper develops a primitive gas recognition system for discriminating between industrial gas species. The system under investigation consists of an array of eight micro-hotplate-based SnO2 thin film gas sensors with different selectivity patterns. The output signals are processed through a signal conditioning and analyzing system. These signals feed a decision-making classifier, which is ob...

This paper simulates the effect of a carbon tariff on China’s trade of industrial products and emission reduction through the GTAP 8.0 model, when the European Union, the United States, and Japan impose a carbon tariff simultaneously or respectively. The conclusions indicate: (1) a carbon tariff will cause a decrease in exports for high-carbon industries and generate an increase in exports for ...

Suitable landfill site selection is a significant step in the integrated management of solid waste. Because of some dangerous industrial waste, landfill site selection is more important. The selection process should be considered different criteria. The purpose of this study was to determine the appropriate location of industrial waste landfill Razi complex by using Analytical Hierarchy Process...
