The object of this work was to improve the experimental procedure of the superconducting transition lab experiment in the “Modern Physics Laboratory” course. A new method of data acquisition has been implemented. In addition, a GPIB connector has been used to communicate the multimeters with a computer, using Python programming, allowing the direct computerized registering of data, instead of m...

Until the late 1980’s electrical calibration systems used to compare primary and secondary voltages and resistance standards consisted of several different components. Systems like the Fluke 7105A and the Datron 4900 were the backbone of the majority of electrical calibration laboratories the world over. These systems were specifically combined to provide a traceable source, according to a set ...

294 Journal of Chemical Education • Vol. 82 No. 2 February 2005 • www.JCE.DivCHED.org It is scarcely possible to go into a modern laboratory and not find computers hard at work. Computer data processing enables us to perform numerous helpful operations otherwise practically impossible: baseline correction, digital differentiation and integration, convolution, to name a few (1–3). Acquiring data...

In this module we will learn the most important principles of making electrical measurements in general, i.e., to obtain voltages and currents using the appropriate instruments and connections, and to understand and minimize sources of error. Furthermore, we will discuss selected electrical measurement methods used to obtain chemical and physical information of liquids, solids, and interfaces. ...

Abstract. Recent advancements and the widespread availability of low-cost microcontrollers electronic components have created new opportunities for developing using low-cost, open-source instrumentation near-surface geophysical investigations. Geophysical methods that do not require ground contact, such as frequency-domain electromagnetics, allow one or two users to quickly acquire significant ...

This paper will discuss the hardware design of a remote monitoring system in micro-hydro power plant. The existence damage to PLTMH due fluctuating voltage causes disruption electricity supply consumers form blackouts, but this is not known by provider at location and load quite difficult achieve there are direct work priorities that do allow it be carried out any time. delay information on con...

AbstractPurpose Online and offline software products can estimate the maximum skin dose (MSD) delivered to patient during interventional cardiology procedures. The capabilities accuracy of several mapping (SDM) were assessed on X-ray systems from main manufacturers following a common protocol. Methods Skin was measured four protocol composed nine fundamental irradiati...

Unidirectional magnetoresistance (UMR) in a ferromagnetic bilayer due to the spin Hall effect (SHE) provides facile means of probing in-plane magnetization avoid complex magnetic tunnel junctions. However, UMR signal is very weak and usually requires lock-in amplifier for detection, even involving $\mathrm{Ta}$ or $\mathrm{Pt}$ with large angle (SHA). Here, we report type UMR, termed anomalous ...

GUM (Guide to the Expression of Uncertainty in Measurement) is a method used for calculating uncertainty measurements. The involves an calculation approach which also constitutes reference international ISO/IEC 17025 standard. In method, all uncertainties are expressed as standard uncertainty. An may incorporate various components where impacts from multiple sources taken into consideration. Re...
