The measurement of the current in industrial electrical devices is often carried out by current transformers. The reliability of these devices is compromised when the measured current is higher than the nominal value, due to the saturation and hysteresis effects of the magnetic core. In this paper, a nonlinear model of the current transformer is identified by means of a separable least squares ...

The Measure Components feature of the MSA (Transmission mode, menu AnalysisMeasure Components) is intended for measuring values of resistors, capacitors and inductors. The MSA automatically chooses an appropriate frequency between 100 kHz and 40 MHz for the measurement. This is not as complete or precise as graphing the component value in Reflection mode, which can show the behavior of the com...

A beam-energy-spread monitor is under development in order to control and stabilize the energy spread of highcurrent single-bunch electron beams for producing a sufficient number of positrons. The author has proposed a new monitor using multi-stripline electrodes in order to reinforce this purpose. This report describes the basic design of the monitor based on a numerical analysis. The analysis...

With the increasing penetration of renewable energy resources, power systems face a new challenge in balancing power supply and demand and maintaining the nominal frequency. This paper studies load control to handle this challenge. In particular, a fully distributed automatic load control algorithm, which only needs local measurement and local communication, is proposed. We prove that the contr...

 This paper presents a comparison of different techniques to capture nominal data for its use in later verification and kinematic parameter identification procedures for articulated arm coordinate measuring machines (AACMM). By using four different probing systems (passive spherical probe, active spherical probe, self-centering passive probe and selfcentering active probe) the accuracy and rep...

We analyse the relationship between nominal algebra and nominal rewriting, giving a new and concise presentation of equational deduction in nominal theories. With some new results, we characterise a subclass of equational theories for which nominal rewriting provides a complete procedure to check nominal algebra equality. This subclass includes specifications of lambda-calculus and first-order ...

previous research has identified the nominal group as the most distinctive feature of the research article title. in contrast, the findings reported in this paper suggest theme/rheme is the dominant structure in title text. theme/rheme structures order and tie nominal groups in titles. when a title starts with a methodological term the first position nominal group acts as a theme marker. thus, ...
