Cross sensitivity of Ionic concentration on Admittance type measurement

An attempt has been made to study theoretically electrical admittance type level measurement and its cross sensitivity with ionic concentration of liquid. The analysis has been made for single and double electrodes and found there is significant cross sensitivity which varies with the ionic concentration of the liquid. This study will help further to design and develop continuous level measurement transmitter in Boiler drum.

SENSITIVITY ANALYSIS OF HIERARCHICAL HYBRID FUZZY - NEURAL NETWORK

To identify the important attributes of complex system, which is high-dimensional and contain both discrete and continuous variables, this paper proposes a sensitivity analysis method of hierarchical hybrid fuzzy - neural network. We derive the sensitivity indexes of discrete and continuous variables through the differential method. To verify the effectiveness of our method, this study employed a man-made example and a remote sensing image classification example to test the performance of our

CO2 sensing characteristics of Sm1-xBaxCoO3 (x = 0, 0.1, 0.15, 0.2) nanostructured thick film

SmCoO3 gas sensor has been developed with high sensitivity for CO2 gas by doping Ba. Nanostructured SmCoO3 and Sm1-xBaxCoO3 (x = 0, 0.1, 0.15, 0.2) were obtained by EDTAGlycol method. The operation temperature falls and sensitivity increases from 425 to 370OC when Ba concentration in SmCoO3 changes from x = 0 to x = 0.1. Ag impregnation over Sm0.9Ba0.1CoO3 sensor, on exposure to CO2 at about 360OC showed an increased sensitivity as well as the response time also decreases. The possible CO2

REFRACTIVE INDEX SENSITIVITY IN THINNED UV AND ARC INDUCED LONG-PERIOD GRATINGS:
A COMPARATIVE STUDY

In this work, a comparative study aimed to investigate the effects of cladding stripping on the external refractive index sensitivity in tapered and UV long period gratings is presented. Here, wet chemical etching combined with microscopic analysis allow us to identify the experimental dependence of the surrounding refractive index (SRI) sensitivity on the cladding radius for both grating types. The experimental results reveal that although in both cases a sensitivity enhancement is achieved by

New approaches for improving selectivity and sensitivity of resistive gas sensors: A review

Resistive gas sensors are very popular and reliable but suffer from low selectivity and sensitivity. Various methods have been suggested to improve both features without increasing the number of sensors in gas detection systems. Fluctuation enhanced gas sensing was proposed to improve gas detection efficiency by analyzing low-frequency resistance fluctuations, and noise parameters can be more informative than the single DC resistance and can advance gas detection systems by improving detection

Effect of TiO2 nano-overlays deposited with atomic layer deposition on refractive index sensitivity of long-period gratings

This paper we discusses an effect of coating longperiod gratings (LPGs) with a thin titanium dioxide (TiO2) overlays on refractive index (RI) sensitivity of the LPG. The overlays have been obtained using atomic layer deposition (ALD) method. The method allows for deposition well-controlled in thickness, well defined in optical properties, high-RI and very conformal thin films as required for optical fiber sensors. For the investigated LPGs we obtained sensitivity of 3490 to 6471 nm per RI unit

EFFECTS OF PLACEMENT ERRORS ON PERFORMANCE OF VLF METAL DETECTOR HEADS

Metal-detector performance depends heavily on the sensor head. Errors in coil placement within the head can lead to degradation in detector performance. Electromagnetic modelling of typical very-low-frequency detector heads shows the effect of coil placement errors on detector sensitivity. Provided the bucking coil ‘tracks’ the receive coil, required error corrections can remain small. A correctly-aligned head could detect a gold ring target at a range of about 12 cm.

Calibration Method for the Wavelength and Uniformity of Pixel Response in Photodetector Arrays

to obtain optical measurements with this cameras. However, digital cameras can also be used as optical measuring instruments knowing their features in depth. Therefore, in this paper is proposed a calibration method for monochrome digital camera using a monochromator and an automatic rotation system. In this way, the uniformity of the pixels response is verified, bad pixels are detected, and the sensitivity curve is obtained. The results show the advantages of the method to find regions of pixels

A MEASURE FOR REGIONAL RESILIENCE TO ECONOMIC CRISIS

The purpose of the study (presented in this article) was to develop a measure of resilience to crisis, one that may be applied to regional data. In principle, such measure can take either positive or negative values. A positive value confirms resilience to crisis, whereas a negative one confirms the absence of resilience (sensitivity/vulnerability). The measure uses growth rates referred to the previous year under the assumption that crisis results in a slowdown in growth, or even in a decline

Molecular Characterization of the cry Gene profile of Bacillus thuringiensis Isolated from a Caribbean Region of Colombia

32.1% of the 28 isolates analyzed, respectively. Surprisingly, reduced lengths of cry4B gene segments were detected in 28.6% of B. thuringiensis samples. The presence of cry10 or cyt1 was not detected in any of the 28 samples of B. thuringiensis, despite the high sensitivity of the assays used. The results show that B. thuringiensis samples from the Colombian Caribbean have atypical characteristics compared to those of Latin America and elsewhere in the world, which is consistent with the idea that

Comparison of voiding cystourethrography and urosonography with second-generation contrast agents in simultaneous prospective study

-generation ultrasound contrast agents and voiding cystourethrography. Methods: From April 2013 to May 2014, 83 children (37 female and 46 male), mean age 3.5 years, age range from 1 month to 17.5 years, underwent prospective simultaneous assessment by contrast enhanced voiding urosonography and voiding cystourethrography, with a total of 166 uretero-renal units evaluated. Results: The sensitivity of voiding cystourethrography and contrast enhanced voiding urosonography were comparable, amounting to
