Biological systems can harness living cells for growth and regeneration, but engineering systems cannot -- or couldn't until now.Qiming Wang and other researchers at the University of Southern Ca...
DEEP LEARNING AND IMAGE PROCESSING FOR AUTOMATED CRACK DETECTION AND DEFECT MEASUREMENT IN UNDERGROUND STRUCTURES
Deep Learning Automated Crack Detection Photographic Tunnelling Surveys
2018/6/4
This work presents the combination of Deep-Learning (DL) and image processing to produce an automated cracks recognition and defect measurement tool for civil structures. The authors focus on tunnel c...
A COST-EFFECTIVE METHOD FOR CRACK DETECTION AND MEASUREMENT ON CONCRETE SURFACE
crack detection depth camera image processing stereovision
2018/3/6
Crack detection and measurement in the surface of concrete structures is currently carried out manually or through Non-Destructive Testing (NDT) such as imaging or scanning. The recent developments in...

2016/4/25
ach fall, monarch butterflies across Canada and the United States turn their orange, black and white-mottled wings toward the Rio Grande and migrate over 2,000 miles to the relative warmth of cen...
Existence of solutions for a higher order non-local equation appearing in crack dynamics
Hydraulic fractures Higher order equation Non-local equation Thin film equation Non-negative solutions periodic Hilbert transform
2015/10/15
In this paper, we prove the existence of non-negative solutions for a non-local higher order degenerate parabolic equation arising in the modeling of hydraulic fractures. The equation is similar to th...

Stanford biologists centuries-old mystery growth triggers cell division
2015/10/13
Cells were discovered in 1676, and almost immediately afterward scientists began wondering why cells are so perfectly small.More than three centuries later, a team of Stanford biologists have zeroed i...

2015/9/25
Since the early 19th century, scientists have worked to unravel the mystery of olfaction, the sense of smell.Olfaction is critical for the survival of species across the animal kingdom. Yet how the br...
Crack detection at concrete construction units from photogrammetric data using image processing procedures
Photogrammetry Change detection Tracing
2015/8/20
Cracks on the surface of a concrete construction are measured and evaluated by a digital photogrammetric method. Knowing these
cracks, the behaviour of the construction, especially using textile rein...
