Study on typical hole defects in AZ91D magnesium alloy prepared by low pressure lost foam casting [PDF]
China Foundry, 2013 The hole defects can easily occur in magnesium alloy castings that are prepared by low pressure lost foam casting (LP-LFC) process when the process parameters such as vacuum, pouring temperature and filling velocity are not properly selected.

A depth image restoration algorithm based on WMF-ACA
上海师范大学学报. 自然科学版, 2021 To solve the problem of holes and noise in the depth image due to the limitation of RGBD camera hardware, a color imageguided method for filling holes in depth image was proposed. Firstly, for the boundary area of the depth image, a weighted mode filter (

An Improved Depth Image Based Virtual View Synthesis Method for Interactive 3D Video
IEEE Access, 2019 Depth image-based rendering (DIBR) is one of the main techniques in interactive 3D video systems. But a critical problem of DIBR is that how to eliminate the holes appearing in virtual view images.

Filling polygonal holes with bicubic patches [PDF]
Computer Aided Geometric Design, 1994 The authors study the problem of filling a polygonal hole in a surface given by \(C^ 1\) data on the boundary of the hole with a \(C^ 1\) surface patch. They give an explicit algorithm that works well for triangular holes but in general does not fit the boundary data and shows undesirable flutter for boundaries that are piecewise curvilinear \(n ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Mechanical properties and energy evolutions of burst-prone coal samples with holes and fillings
International Journal of Coal Science & TechnologyDuring the mining process of impact-prone coal seams, drilling pressure relief can reduce the impact propensity of the coal seam, but it also reduces the integrity and strength of the coal mass at the side of the roadway.

Association Between Motor Pathway Damage and Motor Deficit in Upper and Lower Limb in People With MS
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Corticospinal tract damage is common in people with MS, but the degree of clinical symptoms varies. We hypothesize that corticospinal tract lesions are more extensive and severe in people with MS with motor impairments in both upper and lower limbs.
