Over two decades, this study analyzes drought trends in Diyala Province, Iraq, and It utilizes remote sensing data and rainfall analysis to evaluate the severity and frequency of drought in 2002, 2005, 2010, 2015, 2020, and 2022. The research maps drought distributions in Diyala Province using satellite images from Landsat 7, Landsat 8, and Landsat 9 and analyzes the vegetation health index (VHI), soil moisture index (SMI), and average rainfall data. Results showed increased drought intensity: severe drought expanded from 48% in 2005 to 50% in 2022, and arid conditions increased from 1.1% in 2002 to 17.1% in 2022, as per SMI. Moreover, rainfall analysis reveals varying patterns, with 2022 experiencing lower average rainfall (4.215 mm) an

Migraine classification is considered a complicated research area. Early detection and accurate classification help in determining the appropriate care, speeding recovery from the disease, and avoiding its effects. So, developing a migraine classification system is very necessary. The aim of this work is to suggest a migraine classification model based on a stochastic gradient-boosting ensemble algorithm.

The hidden data is embedded in a manner that remains imperceptible to human observers. In this paper, a stego image that successfully hides the secret information and renders it undetectable to others is created by embedding a hidden message into an original image. The secret message may be text (the doctor’s report of the patient’s case) or maybe a secret image (chest x-ray) or encrypted secret image to increase security and guarantee the patient’s privacy. The cover images may be brain, breast, and lung images. An enhanced LSB technique is introduced, incorporating common LSB and conditional MSB, with a

The upward continuation was used to obtain the residual RTP magnetic maps at elevations 2, 12, 16 and 22 km. These maps are processed by the Total Horizontal Derivative (THD) technique to detect the main lineaments that represent the boundary of subsurface sources or fractures. The high background of THD in the central part of the study area supports the presence of a group of faults between the western and eastern parts of the area.

Recommender systems may face many limitations and challenges, such as the cold start problem, which occurs when there is insufficient or no information about a new user or item. This leads to a decline in the performance of the recommender system. In this paper, we propose a recommendation system based on textual reviews and the deep learning method (RS-TRDL) to alleviate the user cold-start problem.
