Quantifying ambiguities in images using fuzzy set theory has been of utmost interest to researchers the field image processing. In this paper, we present use rough and its certain generalizations for quantifying compare it theory. We propose classes entropy measures based on generalizations, perform rigorous theoretical analysis provide some properties which they satisfy. Grayness spatial are then quantified proposed measures. demonstrate utility effectiveness by considering elementary...
This study reports on high-quality, crystalline, nanostructured TiO2 thin films with large-area coverage prepared by the sol–gel process using PMMA (poly(methyl methacrylate)) as an additive for applications in visible-blind photodetection. The Si/TiO2 p–n junction photodiodes, fabricated through inexpensive yet simple addition of PMMA, exhibit superior characteristics, making them excellent candidates photodetectors operational UV and NIR ranges. to solution significantly enhances...

A neural network model for rainfall retrieval over ocean from remotely sensed microwave (MW) brightness temperature (BT) is proposed. BT data are obtained the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI). The values different channels of TMI Pacific Ocean (163/spl deg/ to 177/spl deg/W and 18/spl 34/spl deg/S) input features. near-surface rate Precipitation Radar (PR) considered as a target. proposed consists with online feature selection (FS) clustering techniques....
Non-destructive evaluation of rope improves the reliability initial identification location significant degradation along a rope. Magnetic flaw detectors, which measure loss metallic area (LMA) and detect local faults (LF) such as broken wires other in ropes, are used to determine wearing. In present paper, non-destructive has been carried out for comparison condition different haulage ropes seven mono-cable aerial ropeway installations through case study over period 1 ½ years.
Abstract Local mapping of piezoelectric response across grains with different crystal planes is crucial to enhance the level understanding behavior wurtzite hexagonal (WH) AlN thin films. To investigate this phenomenon, polycrystalline WH-AlN films were deposited by pulsed-DC magnetron sputtering using a mixture argon (Ar) and nitrogen (N 2 ) varying N content as 5%, 10%, 20% in form AlN/Ti/Si (100) heterostructure. Piezo force microscopy (PFM) was used establish correlation among...
In this paper, a neural network-based method of wire rope fault prediction in system is proposed. This developed based on past observations various parameters for lock coil rope, example number used the system, period test, faults, etc. To capture data from systems, with view to improving accuracy, we have designed multi-layer perceptron network (MLP) realise better performance.
A novel Web surfer model, where the transitions between pages are fuzzy quantities, is proposed in this article. Such a model appropriate when links imprecise. The theoretical aspects of modeling uncertainty associated with discussed. advantages and limitations methodology, which based on theory Markov chains, described. Situations models compared to existing highlighted.
Disadvantages of the coherent technique optical beam scanning, viz., requirements narrow linewidth lasers and variable delays, have been overcome through use a modified PLL principle phase distribution in coupled oscillator.
