Remote classification of images using the new fuzzy clustering algorithm based on the weight

Fuzzy clustering model is an essential tool to find the proper cluster structure of given data sets in pattern and image classification. In this paper, a new weighted fuzzy C-Means (NW-FCM) algorithm is proposed to improve the performance of NW-FCM models for high-dimensional multiclass pattern recognition problems and its result has been compared with the results of FCM, NFCC, and NW-FCM fuzzy clustering algorithm. The methodology used in NW-FCM is the concept of weighted mean from the ...

Ammonia sensor using N-doped graphene quantum dots/polyaniline composite

The present study investigated a resistive ammonia (NH3) gas sensorfabricated using polyaniline (PANI) and N- doped graphene quantumdots (N-GQDs) dopant on a transparent and flexible substrate withinterdigitated electrodes. The sensing response of the PANI to NH3increased from 9.12 to 86.91 at 1500 ppm with the addition of 50 wt%N-GQDs. This shows that sensing response of N-GQDs/PANI sensorfor NH3 detection is enhanced by the N-GQDs added into PANI. It canbe attributed to the pi;- pi; ...

Prediction of Water Quality of Ajichay River using developed Artificial Neural Network and Supporting Vector Machine Models

International efforts have been launched to save the endangered Urmia Lake as one of the largest natural lake worldwide. Ajichay River located in East Azarbaijan province, Iran, is one of the main rivers discharging into this lake and, thus, its water quality can directly affect the Urmia Lake ecosystem and life. In this research, we develop and propose two new numerical packages on the basis of Artificial Neural Network (ANN) and Supporting Vector Machine (SVM) models to estimate the monthly ...
