The guide refers to the probability theory, as the most known and used mathematical tool to deal with distributions of values. However, the probability theory is not the only tool to deal with distributions of values and is not the most suitable one when the values do not distribute in a totally random way. A more general theory, the theory of the evidence should be considered that encompasses the probability theory and the possibility theory. This paper recalls the fundamentals of the theory of the evidence and shows how the random-fuzzy variables can be framed within this theory and usefully employed to represent the result of a measurement together with its associated uncertainty. Mathematics is defined on the random-fuzzy variables, so that the uncertainty can be processed and simple examples are given showing the effectiveness of these variables in expressing the result of a measurement and its uncertainty in full agreement with the spirit of the IEC-ISO Guide.","PeriodicalId":135321,"journal":{"name":"Proceedings of the 20th IEEE Instrumentation Technology Conference (Cat.

This paper describes a method to create very pure signals, such as sine waves, dual-tones or multi-tones, using only power measurements. The signals are generated with an arbitrary waveform generator (AWG). Any unwanted spectral line is removed, independent of its exact origin. This allows to apply the correct signal to the ADC under test, even if the signal source is not perfect or is followed by filters or amplifiers with a small non-linear distortion. Measurements are used to demonstrate the capabilities of the method.","PeriodicalId":135321,"journal":{"name":"Proceedings of the 20th IEEE Instrumentation Technology Conference (Cat.

The objective is to develop ultrasonic sensors that 1) can be attached permanently to a pipeline wall, possibly as a spool piece inserted into the line, and 2) can clamp onto an existing pipeline wall and be movable to another location. Two examples of systems based on pulse-echo and transmission signal analysis are used to illustrate some of the capabilities of ultrasonic online measurements with technologies that have applications in the nuclear, petrochemical, and food processing industries.","PeriodicalId":135321,"journal":{"name":"Proceedings of the 20th IEEE Instrumentation Technology Conference (Cat.

Such analysis describes both the timing errors imposed by random clock-jitter and fixed periodic clock-skew.

In this paper we discuss the advantages of broadband time-domain preliminary compliance measurement techniques applied to all types of electromagnetic interferences. The digital signal processing of electromagnetic interference measurements allows emulating in real-time the various modes of conventional analogous equipment, e.g., peak, average, root mean square, and quasi-peak detector mode. Since time-domain techniques allow processing the whole amplitude spectrum in parallel, the measurement time may be reduced by at least one order of magnitude. Compliance measurement results for conducted and radiated emissions obtained with the time-domain electromagnetic interference (TDEMI) system are shown. The TDEMI system has a real-time bandwidth of 1.5 GHz. Measurement techniques for nonstationary signals and single events are discussed.","PeriodicalId":135321,"journal":{"name":"Proceedings of the 20th IEEE Instrumentation Technology Conference (Cat.
