The problem of the research is that the level of performance of wrestling players is not at the required level, and from the researcher's point of view, he believes that one of the reasons for this is due to the weakness of the player's response speed, since wrestling requires a quick reaction, through which the wrestler's level of skill performance can improve. The research aimed to prepare special exercises and know their effect on the speed of motor response and performance of the snatch skill for wrestling players aged under (16) years old. It was assumed that there are statistically significant differences between the experimental and control groups in the post-tests in both the speed of motor response and the level of performance o

Digital image manipulation has become increasingly prevalent due to the widespread availability of sophisticated image editing tools. In copy-move forgery, a portion of an image is copied and pasted into another area within the same image. The proposed methodology begins with extracting the image's Local Binary Pattern (LBP) algorithm features. Two main statistical functions, Stander Deviation (STD) and Angler Second Moment (ASM), are computed for each LBP feature, capturing additional statistical information about the local textures. Next, a multi-level LBP feature selection is applied to select the most relevant features. This process involves performing LBP computation at multiple scales or levels, capturing textures

Reservoir pressure plays a significant role in all reservoir and production engineering studies. It is crucial to characterize petroleum reservoirs: by detecting fluid movement, computing oil in place, and calculating the recovery factor. Knowledge of reservoir pressure is essential for predicting future production rates, optimizing well performance, or planning enhanced oil recovery strategies. However, applying the methods to investigate reservoir pressure performance is challenging because reservoirs are large, complex systems with irregular geometries in subsurface formations with numerous uncertainties and limited information about the reservoir's structure and behavior. Furthermore, many computational techniques, both numerical and
