TL;DR: Energy bandwidth modelling is proposed as the link between modelling and information and an incisive top-down view of the functions and structures of information systems in general and measurement systems in particular is achieved.

TL;DR: In this article, the authors examined the problems involved in such measurements and the standards and specifications under which they are made and concluded that some causes of error are not yet fully understood and the effects of differences in optical microscopes are not taken into account.

TL;DR: In this article, the authors consider the problem which the diversity of measurement and instrumentation science and technology poses for the teaching of the discipline and propose a design-oriented teaching approach as the solution.

TL;DR: An image processing technique for the high-speed measurement of particle-size distributions based on sampling is proposed, which can be performed in real-time processing even with a microcomputer.

TL;DR: The measuring system described can be used to record measured signals of not too high a limit frequency to enable documentation or further processing of these signals, and has proved itself in practical use for recording biosignals and for storing events.

TL;DR: In this article, it was shown that the low-temperature scale of Jan, Christian, Pearson and Templeton (1958) was in error by 0.3 μV/K above about 30 K. The measurements have all been cross checked by showing that Kelvin's S = ∫(μ/T)dT is valid for measurements on pairs of metals.

TL;DR: A new approach to the testing of digital devices is discussed which can, in many cases, save diagnostic hardware and software.

TL;DR: In this article, the laser interferometers for angle measurement in a wide range have been presented, which are the systems based on the modified Twyman-Green interferometer principle.

TL;DR: In this article, the balance beam is replaced by a system of parallel lever with elastic joints, which guide the balance pan and the force coil in a vertical path of deflection.

TL;DR: The various types of enzyme electrodes which have so far been reported are described, and some indication is given of the problems of their practical deployment.

TL;DR: In this article, the authors consider the problem of selecting an appropriate interval between interventions, because in actual operation the time elapsed before a preventive intervention is really necessary varies a great deal from one situation to another due to the different working conditions and the different lives of components.

TL;DR: A systematic method to generate tests for microprocessors using a general model for the microprocessor represented by a set of mechanisms implementing various microprocessor functions, and recommendations facilitating the test generation for the data manipulation mechanisms.

TL;DR: In this paper, basic parameters for the determination of the conversion efficiency as well as the energy loss of solar cells are described, and different methods for solar cell calibrations are presented.

TL;DR: In this article, the authors investigated the effect of the strain gauges on the measuring spring and the measuring error at low thickness of a measuring spring on the performance of a small force transducers (MFTs).

TL;DR: In this article, a highly accurate measuring equipment has been developed, using CCD camera, length-measuring instrument with He-Ne laser, electric micrometer and microcomputer system.

TL;DR: The increasing use of intelligent sensors and instrumentation in many aspects of modern life is discussed and progress reviewed.

TL;DR: The means and procedures at the present time used at IEN in providing and maintaining the units of the electrical quantities in the DC and low-frequency field are described in this article.
