Application of image analysis in the fungal fermentation of Trichoderma reesei RUT‐C30
Biotechnology Progress, 2011AbstractTrichoderma reesei was grown in a stirred‐tank bioreactor (STB) and a reciprocating plate bioreactor (RPB) at four different agitation speeds. A semiautomatic image analysis protocol that was developed to characterize the mycelium morphology during the fermentation process based on four morphological types (unbranched, branched, entangled, and ...

A new method for automatic detection of rut feature based on road laser images
SPIE Proceedings, 2009There are some disadvantages existing in traditional artificial method of detecting road rut feature, such as consuming time, consuming energy, low accuracy and danger. In order to solve those problems listed above, a new method of detecting features automatically based on the laser image processing technology is proposed. The first step is to start

Estimation of water film depth for rutting pavement using IMU and 3D laser imaging data
International Journal of Pavement Engineering, 2019Rutting is a kind of pavement structural damage caused by repeated traffic loads, which is served as ‘reservoir’ in rainy days, and ponding water would bring in potential hydroplaning issues.

Profiling of external deformation in asphalt pavement rutting using image analysis method
2013 IEEE 9th International Colloquium on Signal Processing and its Applications, 2013The quality of road surface exerts a great influence on the road safety. Characterization of the asphalt surface structure using two-dimensional (2-D) imaging techniques is an economically efficient approach. The present research focused on introducing a more elaborate method of characterization of external structure, and proposing new index to relate ...

Abstract The contact structure of asphalt mixtures has been considered as an important micromechanical mixture property related to the rutting performance. In this study, a two-dimensional (2D) image acquisition and processing procedure was utilized to acquire the contact structure of asphalt mixtures with varying compactness, gradation types ...

This paper systematically investigates the changes in asphalt concrete (AC) microstructure caused by full-scale accelerated pavement testing with a heavy vehicle simulator (HVS), using X-ray computed tomography images taken before and after HVS rutting tests. A viscoelastic micromechanical finite element modeling was also used to investigate effects of

Permanent deformation is known as one of the most critical distresses observed in asphalt pavements, and is known to depend on asphalt binder, aggregates and voids, which are the components of asphalt mixture. This study is an effort to investigate the effect of asphalt binder modification type and aggregate structure on rutting resistance through ...
