On Line Monitoring of Acrylamide Formation
2006A system to monitor the formation of acrylamide in model systems and from real food products under controlled conditions of temperature, time and moisture content has been developed. By humidifying the gas that flows through the sample, some control over moisture content can be affected. Results are presented to show the validity and reproducibility of

CORROSION 1973, 1973
The need for on-line corrosion monitoring has become increasingly important to the chemical process industry for several reasons. New plants are trending toward large, single-line process units which must achieve long continuity of operation to be economical. The new plant may be an enlarged old process with some innovations, or it may be a new process

On-line voltage stability monitoring
IEEE Transactions on Power Systems, 2000This paper presents a new methodology for online voltage stability assessment, consisting of two steps. Firstly, the time evolution of the power system operating state is modeled with the help of a forecasting-aided state estimator; secondly the voltage collapse point is determined through an extrapolation technique based on tangent vector behavior ...

On-Line Voltage Stability Monitoring
2018 IEEE International Symposium on Circuits and Systems (ISCAS), 2018This paper reviews the basic assumptions of real-time voltage instability monitoring, based on impedance matching and compares it with a new method based on either phasor measurement units (PMU), or distance relays. It is shown that the limitations associated with impedance matching assumptions are overcome by the proposed method, which can accurately ...

On-line particulate emission monitor
Powder Technology, 2003Abstract The design and development of a coaxial capacitance transducer for on-line measurement of particulates in air is described. The system's performance is evaluated in response to changes in a number of operating parameters including relative humidity (8–78%), temperature (20–100 °C) and flow velocity (6.5–15 m/s).

On-Line Monitoring and Identification of Bioaerosols
Analytical Chemistry, 2006Fast analysis of bioaerosols in clean room environments is necessary in order to prevent contamination of pharmaceutical products, minimize machine downtimes, or both. The detection and identification of microbes will be carried out in several steps: After impaction of the aerosol on a surface, the particles are presorted with glancing light ...

Conductivity: On-Line Monitoring of Dialysis Adequacy
The International Journal of Artificial Organs, 1998Cardiovascular disease and the inadequacy of delivered dialysis are the main factors determining morbidity and mortality in dialysis patients. We have already demonstrated that a conductivity kinetic model makes it possible to match interdialytic sodium loading and intradialytic sodium removal (the main factor determining cardiovascular morbidity ...

On-line biomass monitoring by capacitance measurement
Journal of Biotechnology, 1992An in-situ, steam-sterilizable capacitance probe was used to follow the biomass concentration on-line, in bioreactors from 20 to 2000 l total volume. Microbial cultures of Saccharomyces cerevisiae, Pichia pastoris and Streptomyces virginiae were grown in batch and fed-batch culture in both defined and complex media in order to demonstrate the wide ...
