in this paper a novel process monitoring scheme for reducing the type і and type іі error rates in the monitoring phase is proposed. first, the proposed approach uses an augmented data matrix to implement the process dynamic. then, we apply independent component analysis (ica) transformation to the augmented data matrix, and eliminate the outliers using the local outlier factor (lof) algorithm....

We present the design and implementation of Persistent Modula-3, a compiled, optimized, persistent programming language. The design allows the evaluation of performance aspects of persistent programming languages, while the implementation supports the development of compile-time mechanisms for optimizing persistent programs. We present several optimizations in detail, and outline further optimi...

In this correspondence, the linear complexity over of Lempel–Cohn–Eastman (LCE) sequences of period 1 for an odd prime is determined. For = 3 5 and 7, the exact closed-form expressions for the linear complexity over of LCE sequences of period 1 are derived. Further, the trace representations for LCE sequences of period 1 for = 3 and 5 are found by computing the values of all Fourier coefficient...

In this article, we use a genetic algorithm to obtain an economically optimal preventive maintenance frequency for different equipment, the parts inventory policy (number and type of spare parts to keep in stock), and labor allocation in process plants. To assess cost, we improved a previously published Monte Carlo simulationbased maintenance model (Nguyen et al. Ind. Eng. Chem. Res. 2008, 47(6...

Although many PID tuning approaches are available, it is not easy to find a method that does not require any engineer/operator interference. In this work, we present a fully automated approach for PID tuning based on relay feedback. This method involves sending the relay feedback test data from PLCs (Programmable Logic Controller) into a historian, analyzing the test data using a tuning applica...

Endemic goitre constitutes an important disease problem in many parts of the world. Kelly and Sneddon (1960), in an extensive review of the literature, estimated the number of goitrous subjects in the world to be about 200 million. Goitre has also been reported to be endemic in many areas of Southeast Asia including Sarawak in Malaysia (Fig. 1). Studies (Polunin, 1971; Alexander, 1979) indicate...

The Tennessee Eastman (TE) process, created by Eastman Chemical Company, is a complex nonlinear process. Many previous studies focus on the detectability of monitoring a multivariate process by using TE process as an example. Principal component analysis (PCA) is a widely used dimension-reduction tool for monitoring multivariate linear process. Recently, the kernel principal component analysis ...
