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 ...

"On-Line Monitoring of Power Transformers"
IEEE Transactions on Power Apparatus and Systems, 1985A microprocessor based Transformer Monitoring System (TMS) has been developed to provide the continuous on-line monitoring and analysis of power transformer operating parameters. With the TMS, changes in the operating condition of the transformer can be determined from a historic data base and potential problems can be identified prior to becoming ...

On-line respiratory gas monitoring
Computers and Biomedical Research, 1973Abstract An automated system for monitoring vital signs and respiratory gases is described. By careful selection of analog and digital hardware, a relatively small and inexpensive system can be made to perform complex monitoring functions on a practical clinical basis.

On-line monitoring: a tutorial
Computer, 1995Online monitoring can complement formal techniques to increase application dependability. The article outlines the concepts and identifies the activities that comprise event based monitoring, describing several representative monitoring systems. It focuses on four areas: dependability, performance enhancement, correctness checking, and security. >

Journal of Electronic Testing, 1998
Sequoia‘s fault-tolerant computers were designed subject to some rather rigid constraints: No single hardware malfunction can generate an undetected error; an integrated circuit is a “black box” that can fail in arbitrary ways, affecting an arbitrary subset of input and output signals; faults can be transient or intermittent with arbitrary durations ...

Experiments in line quality monitoring
IBM Systems Journal, 1976This paper describes an experimental line quality monitoring (LQM) system, which has been in regular operation in several IBM locations. The LQM system uses a System/7 to gather information about the analog phenomena that occur on telephone data transmission lines. It gathers the information without taking the lines out of service.

On-line monitoring of computer systems
Third IEEE International Workshop on Electronic Design, Test and Applications (DELTA'06), 2006The paper deals with the problem of on-line diagnosis of computer systems. It is based on three monitoring techniques related to system event logging, performance and resource usage measurements. This approach is illustrated with practical results.

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 ...

IEEE Transactions on Systems Science and Cybernetics, 1968
This paper describes a system for monitoring a General Purpose Simulation System (GPSS) run while the run is in progress. The on-line monitor provides the ability to select and display statistics related to the GPSS entities. The IBM 2250 and the IBM 2260 display consoles are used as interface devices.

CVP Lines: Monitoring and Maintaining
The American Journal of Nursing, 1978heart function in relation to blood volume and are helpful in determining a patient's fluid volume requirements. In addition, a CVP line may be used to administer fluids and drugs. Maintaining the patency of the system, monitoring pressures accurately, and preventing infection are the primary goals in caring for patients with CVP lines.
