Optimization of measurement processes under metrological provision for complex technological systems

A dynamic problem of optimizing a selection of measured quantities and measuring devices is formulated. For a class of linear dynamic objects, an optimal controller of the measurement processes is designed. An example of solving an optimization problem for metrological provision of a testing equipment is presented.Translated from Izmeritel'naya Tekhnika, No. 8, pp. 3–5, August, 1994.     

Optimization of planning for the metrological servicing of working standards for measurement technology laboratories

A method is developed for managing the sequence of a metrological service for working standards of verification laboratories based on considering invariant-group models of the evolution of metrological characteristics.Translated from Izmeritelnaya Tekhnika, No. 11, pp. 58–63, November, 2004.

Design and metrological applications of a low noise, high electrical isolation measurement unit

A digitally controlled voltage generation and measurement unit optimised for high-precision electrical metrology is described. It is optically isolated from the controlling computer and contains specially constructed isolated power supplies allowing continuous operation without the need to recharge batteries. The source has a simple microcontroller that is pre-programmed with firmware to control operation and to carry out simple repetitive measurement tasks, such as generation and quantisation of signals using uniform sampling. The merits of the developed unit are demonstrated by three example applications: (i) the application of the unit to control a Josephson voltage standard, (ii) the implementation of a transfer standard for the calibration of the electronic instrumentation of fatigue testing machines traceable to the primary electrical standards and (iii) the force measurement of an ion thruster traceable to the primary electrical standards at the industrial user level.     

Performance evaluation for mobile metrological suites

Performance estimation is considered for mobile metrological suites. Two general performance parameters are introduced. A method is described for determining the effects of groups, subgroups, and individual influencing factors on the performance.

Working tubes for metrological constriction devices

To improve the accuracy in flow measurement, the tubes connecting to the constriction are turned to exact diameters on a lathe. The internal diameter is used in designing the constriction device. Translated from Izmeritel'naya Tekhnika, No. 6, pp. 60–62, June, 2000.
