Addressing the shortfall in process control systems
There is a shortfall or imbalance between the steady increase in the complexity of process-related technologies, and the much slower rate of increase in the sophistication of process control systems. This paper explores two avenues along which this imbalance can be attacked. The first would more aggressively exploit opportunities for incremental instrumental improvements, while the second ...

Energy consumption model for wastewater treatment process control
Wastewater treatment must satisfy discharge requirements under specified constraints and have minimal operating costs (OC). The operating results of wastewater treatment processes (WWTPs) have significantly focused on both the energy consumption (EC) and effluent quality (EQ). To reflect the relationship between the EC and EQ of WWTPs directly, an extended Elman neural network-based energy ...

Schedule performance measurement based on statistical process control charts
In a job–shop environment, achieving a schedule that is on target is difficult due to the dynamism of factors affecting the system. In this paper the Shewart's Individuals control chart is applied to a scheduling process for the purpose of measuring schedule performance. The charts are applied to monitor the deviations of actual from scheduled process times for jobs on a process machine. Data ...

Implementation of a process internal control to monitor the performance of real-time PCR assays for the detection of
Vibrio cholerae in waterThe process control utilised in this study was an Escherichia coli (E. coli-GFP) strain carrying a chromosomally integrated copy of the green fluorescent protein (gfp) gene of the jelly fish Aequorea victoria. Application of the process control involved spiking samples with the E. coli-GFP containing cells and detecting gfp using real-time polymerase chain reaction (PCR). The process control ...

Cycle-time determination and process control of sequencing batch membrane bioreactors
In this paper a method to determine the cycle time for sequencing batch membrane bioreactors (SBMBRs) is introduced. One of the advantages of SBMBRs is the simplicity of adapting them to varying wastewater composition. The benefit of this flexibility can only be fully utilised if the cycle times are optimised for the specific inlet load conditions. This requires either proactive and ongoing ...

Teron SL670e and Teron SL670e XP: EUV Reticle Quality Control
Extreme ultraviolet (EUV) lithography is a key technology inflection for the semiconductor industry. While shifting the scanner wavelength to EUV has enabled printing of the smaller pattern features required for ≤5nm design node chips, it has also added tremendous complexity to the equipment, reticles, resists and other infrastructure required to support EUV lithography. New defect mechanisms ...

Identification for process control and bioengineering: open loop frequency domain estimation
A previous paper has outlined a novel method for estimation of the parameters (including the time delay) of a general Single Input, Single Output (SISO) process model from an appropriate number of arbitrarily specified points on the process frequency response. The method involved combining an analytical approach with a least squares approach using a gradient algorithm, to provide accurate ...
