The effectiveness of the proposed method is confirmed by testing its performance in processing an industrial dataset. The intended dataset contains 4479 X-ray images and belongs to six groups: cavity, cracks, inclusion slag, lack of fusion, shape defects, and normal defects. The devised ...
From this dataset, specific tomogram slices were selected to highlight the crack propagation within the material. After the specimens were scanned, they were heat tinted and broken open. Fractured surfaces of the C(T) specimens were observed using optical techniques, SEM secondary electron imaging ...
The low evaporation field of the precipitates changes the local magnification factor resulting in a focusing of matrix atoms into the precipitate region on the detector and is signaled by higher than physical atom densities in the reconstructed dataset32,33,34,35,36,37. These artifacts can result ...
For X-ray weld defect detection, this paper proposes AF-RCNN object detection framework with the application of attention mechanism because defect images have too many small defects, and feature information of small defects are more likely to be missing during the convolution. First of all, the ...
This study primarily investigates the natural radioactivity level in alkaline rocks collected from the Wadi El-Dib ring complex (WDRC) in North Eastern Desert of Egypt, and assesses potential health risks associated with their use as decorative building
In addition, it is possible to perform high-speed scanning not only of stationary targets but also of fast-moving targets. In contrast to the harmful radiation effects of techniques such as X-ray imaging, IRT is radiation-free and suitable for long-term and repeated use. Figure 1 illustrates...

The intended dataset contains 4479 X-ray images and belongs to six groups: cavity, cracks, inclusion slag, lack of fusion, shape defects, and normal defects. The devised technique...
Oxford PV has announced a five year research project with the University of Oxford to develop a thin-film multi-junction perovskite solar cell, with a target 37% efficiency and long term stability. The GBP 5 million ... Raynergy Tek sets new world record for OPV power conversion efficiency ...
Figure 1. The framework of the proposed model used to predict the UTS. 3.1. Dataset Preparation The data utilized for this study consisted of three datasets. The first dataset was used by [34]. The other two datasets constitute the dataset generated in this study. These datasets contain nine...
To this end, we evaluate these NMS methods on a dataset of steel surface defects using the well-known object detection models YOLOv7 and EfficientDet. The details of the datasets and the hyperparameters of the models are described in the later sections. 3.1. Dataset Description In this paper...
