Article Synopsis
- Tensile tests on electroplated copper (Cu) films revealed that the strength of these films is closely linked to the density of their nano-twin grain structures, with higher densities resulting in greater fracture strength.
- The density of the nano-twin structure can be controlled by adjusting the concentration of gelatin in the Cu-sulfate electrolyte solution.
- Analysis showed that plastic deformation in these nano-twinned films is primarily caused by a de-twinning mechanism activated during necking, involving the formation and collapse of ledges due to dislocation interactions with twin boundaries.
The introduction of beam intensity control concept in current radiotherapy techniques has increased treatment planning complexity. Thus, small-field dose measurement has become increasingly vital. Polymer gel dosimetry method is widely studied.

Fingerprint evidence plays an important role in solving criminal problems. However, defective (lacking information needed for completeness) or contaminated (undesirable information included) fingerprint patterns make identifying and recognizing processes difficult. Unfortunately.

This method provides an efficient solution to normalize skew distorted vehicle license plate images. The Hough transform is used to estimate the license plate position and the normalization angle.
