Although of little use to professional users, the features of analogue instruments are covered in this chapter because students are quite likely to meet these when doing practical work associated with their course. As far as digital oscilloscopes are concerned, the basic type of instrument used is...
Conclusions and future work This paper proposed a new method for fault diagnosis of building electrical systems based on the combination of VMD-MDI and QGA-SVM. Firstly, the resistance fault signal is collected by the building electrical experimental platform MA2067 and the instrument Eurotest 61577...
In this work, we overcome these challenges by introducing a hybrid magnetic-mechanical-electrical (MME) core-sheath fiber that is patterned using a one-step coaxial printing method. The MME fiber is composed of a liquid metal core and a soft magnetoactive composite sheath that together enable pr...
In this work, a rapid and selective method was successfully developed using the magnetic molecularly imprinted polymer (MMIP) as sorbent for the extraction... X Zhang,L Chen,X Yang,... - 《Journal of Chromatography B Analytical Technologies in the Biomedical & Life Sciences》 被引量: 91发表...
gold card holder (typically an Installation Electrician holding a Registered Electrician status). The criteria for the assessment are based around safe working of electrotechnical allied trades carrying out associated installation works with an emphasis on when to make sure electrical installation work is...
SiC-based nonlinear resistive grading materials have been used for end turn stress grading of form-wound rotating electrical machines, such as high voltage motors and turbine generators, over a long period. Although these materials work well under power frequency, the electric field and local heating...
Another significant problem affecting conductivity is the homogeneity and anisotropy of the sample. Up to now, there are four physical forms forMOFsamples, and they are closely related to the electrical conductivity measurements, including microcrystalline pellets, polycrystalline films/membranes, single dom...
The highest peak position of g+−, with its heavy tail, is at ∼5 Å, indicating the solutions are predominantly in discrete ionic form. Meanwhile, the heights of the first and second peaks gradually decrease with decreasing temperature, which is consistent with the previous work by Yoon...
The current work is mainly devoted to the synthesis, structural, electrical, and magnetic characterization of Sr1−XLaXFe12O19 (X = 0.2–0.8) (SLFO) nanoparticles synthesized via the hydrothermal technique. The hexagonal peaks were determined using X-ray diffraction analysis. The obtained re...
and the relative humidity was set to ≥90%. The fermentation cycle of black tea is usually 3 to 4 hours. In order to improve the generalization of the predicted model, the fermentation cycle was extended to 6 hours so that the sample set can cover different fermentation stages (slightly...
