Hand Depth Image Denoising and Superresolution via Noise-Aware Dictionaries by Huayang Li, Dehui Kong, Shaofan Wang, Baocai Yin

“…Compared with traditional OMP, NAOMP adds a residual reduction step which effectively weakens the noise term within the residual during the residual decomposition in terms of atoms. Experimental results demonstrate that the bilateral phase and the NAOMP-based learning dictionaries phase corporately denoise both virtual and real depth images effectively.…”

Computational fracture and thermal analysis of glass-ceramics using ReaxFF reactive molecular dynamics simulations by Domenica Rodriguez, Hyung Sub Sim, Eungyo Choi, Sung-Yup Kim, Jinsu Nam, Seungho Kim, Sungwook Leo Hong

“…To address this, we utilized reactive molecular dynamics (RMD) simulations to fundamentally investigate the behaviors of various glass-ceramic materials at the atomic scale. The RMD results provide valuable insights into the mechanical and thermal properties of glass-ceramics, demonstrating that substituting Li/Al in the base glass significantly enhances these properties, while the incorporation of crystal grains further improves the mechanical performance of the amorphous glass-ceramics. …”
