TL;DR: In this paper, the authors analyze the possibility that measurement science, and therefore measurement itself, can be properly founded, given the common assumption that measurement plays an important role in the foundation of science.

TL;DR: In this article, the authors proposed a method to correct the noise bias for the roughness parameter Rq which is equivalent to the standard deviation by considering the decrease in Rq once an average over multiple measurements is made, an unbiased value for Rq is estimated by extrapolation.

TL;DR: In this paper, an implementation of artificial neural networks for multi-frequency eddy current testing on conducting layers (aluminum, copper and ferrous tubes) has been presented, which is a fast and effective method for detecting and sizing most of the flaws in conducting materials.

TL;DR: In this paper, a free active cylinder bulk-modulus and the birefringence effect on a fiber Bragg grating (FBG) is implemented by demodulating fiber BRG peak splitting caused by transverse stress differences in the core of a single mode fiber, which is bonded on the exterior surface of the cylinder.

TL;DR: In this article, a software package that measures the dimensions and numbers of checks in scanned images of weathered wood surfaces has been described, and a black-and-white image is then produced in which checks are shown black on a white background.

TL;DR: In this paper, the temperature influence of surfaces surrounding a sample on its emitted and reflected radiation during high temperature pyrometry (T ǫ>900 K) was investigated.

TL;DR: In this paper, an improved BP algorithm and ANN data fusion architecture have been presented to improve learning speed and avoid local minimum points in error curve, which can be used in many different fields, such as battlefield surveillance, traffic monitoring, law enforcement and so on.

TL;DR: A new method has been developed where white light interferometry (WLI) is used to study the progression of dental erosions in vivo, which opens the possibility of following the progress of dental enamel progression in vivo.

TL;DR: In this paper, the authors propose a shared interpretation of the information given to them by recognising that in either case p is the proportion of independent intervals calculated over time that contain their respective measurands.

TL;DR: A prototype telemedicine system, which provides human electrocardiogram signals transferring via telephone network, has properties, which covers the management of electronic records of patient and access to hospital’s data base system.

TL;DR: In this article, it is shown that it is possible to determine properties of wood using microwave scanning techniques using the measured values from a microwave imaging sensor, and the purpose of this study was to verify the measured value from a microwaved imaging sensor.

TL;DR: In this paper, a fast stereometric system has been developed to measure free-form surfaces of railway concrete sleepers and calculate track and rail seat dimensional tolerances, which allows non-contact measurement of soft parts to make possible efficient inspection of post-stressed production before curing of the concrete, and speed up the digitizing process reducing some difficulties associated with stereo vision.

TL;DR: In this article, a fuzzy sensor for measuring the average temperature of the air leaving the mixing box of an air-handling unit is presented. But the measurement of the mixed air temperature is notoriously difficult because of spatial variations in the air temperature and velocity immediately downstream of the mixing-box.

TL;DR: In this article, a novel electromagnetic force sensor has been proposed, where a couple of fiber Bragg gratings (FBGs) are mounted at either side of the cantilever.

TL;DR: Based on the principle of operation of self-excitation vibrating-wire sensors, the experimental results of the designed excitation circuit are reported in this article, where the proposed model is implemented by an 8-bit microcontroller while maintaining the intrinsic characteristics of the vibratingwire sensors.

TL;DR: In this article, an analytical and experimental results are presented on the fluxgate magnetometers that adopt a time readout technique based on the characterization of the times spent by the core magnetization in each of the two stable equilibrium states of the potential function, that underpins the dynamic of a typical ferromagnetic core, when a (carefully configured) periodic excitation signal is applied.

TL;DR: In this paper, the authors describe a set-up which allows the measurement of the temperature field in the depth of injection moldings throughout the length of the injection molding cycles and after ejection as well.

TL;DR: In this article, an electronic conditioning circuit is presented which converts electric conductivity into a value of continuous voltage, and a hardware solution is proposed to do the conductivity temperature compensation.

TL;DR: Experimental results show that the proposed method exploiting the texture features of ultrasonic images has potential utility for computer-aided diagnosis of myocardial heart disease.

TL;DR: This procedure uses the standard deviation as a measure of precision and assures, based on the Sheppard correction, that rounding increases the standard deviations of the series of rounded values only slightly due to rounding.
