A computer-aided on-line monitoring system was established and applied for plant cell bioprocesses, with Perillafrutescens as a model cell [86]. The cell concentration was successfully measured on-fine and in situ with a laser turbidi-... 

The analysis of cell components and cell characteristics gives information on the metabolic and physiological states of the microorganisms that could be valuable for process monitoring and control. Unfortunately, on-line monitoring systems for cell components or cell characteristics are rare.

In this paper, we have presented a new on-line monitoring system to help oil and gas companies monitor the performance and availability of their machines. This helps in reducing down time and preventing trips. The article presents rules to monitor the performance of the axial compressor and output of the machine, as well as a rule to monitor fuel consumption, which is also applicable at part load conditions. Physics-based availability rules to monitor the wheelspace temperatures and combustion process were also shown. Vibration rules based on a correlation with key parameters as well as a new rule to measure natural frequencies were also introduced. 

Recent developments in extmsion equipment include the increased use of microprocessor control systems and a variety of on-line monitoring systems for product quality assurance. 

On-line monitor system of the time profile of optical reflectivity was installed to check the phase-change condition of the DVD sample. As shown in Fig. 7, a He-Ne laser beam was guided through the transp>arent substrate onto the backside of the sample, since the...

From the presented review, it is apparent that at present we do not have at our disposal a reliable and effective electrochemical technique enabling rapid and accurate determination of the corrosion current of metals in cathodic polarization conditions, although achievement of the assumed aim seems much closer. At present, there is a significant demand for such types of methods, which could be the basis of modem on-line monitoring systems of corrosion of polarized structures, and would introduce an expected technological breakthrough in the control of the effectiveness of electrochemical protection. 

Work is being carried out on new on-line monitoring systems of CP effectiveness. The start of production by some firms of complicated portable apparatus for electrochemical investigations, allowing measurements in field conditions, should be mentioned. The SOLARTRON SI 1280 corrosion monitor and Gamry Instruments apparatus can be mentioned here. The development of apparatus in this direction holds...
