A DNN learning architecture is proposed by Mohsen et al. to classify brain tumors using MRIs.
Jemimma et al. introduced a Local Directional Pattern (LDP) based deep learning classification technique that extracts features from image data segments using a probabilistic fuzzy C-means clustering (PFC) algorithm.
A brain tumor grading system is being proposed by Sajjad et al., which first do segmentation of the tumor region by using deep learning-based architecture namely Input Cascade CNN and then implemented augmentation (rotation, filliping, skewness, and shears for geometrical changes) to increase the dataset size to feed neural architecture to get satisfactory results.

Abstract.
Materials and Methods The corrosion test was done using three-electrode-cell system with platinum as the counter electrode, Ag/AgCl (3M KCl) as the reference electrode and the aluminum (Al-6061) specimen as the working electrode.

This analysis is based on own work [9] and that of Lentz et al. [10].
Comparison of stability maps Lentz et al. [10] applied the concepts of Prasad et al. [1,11,12] using the instability parameter defined by Eq. (9) to construct a instability map for the magnesium alloy WE54 at e=0.5.
For comparison, we first determine the Garofalo parameters according to our model RCR [13] and then we constructed stability maps by means of our stability equations, Eqs. (11) and (13), but using Lentz el al. data.
These parameters do not differ much from those obtained by Lentz et al. [10]: A=3.5 E14, Q=224 kJ/mol, n=3.2, a=0.014.
Stability maps using Lentz et al. [10] data for the WE54, a) 1st Lyapunov criterion, b) 2nd Lyapunov criterion.

The solar pond at El Paso, Texas, was the first solar pond in the world to provide heating for the industrial purposes, and the first solar pond in the USA used in the electricity generation applications.
The automated instrumentation system at El Paso Solar Pond employed a sensor head which was driven by a computer controlled stepper motor.
