Gas driven fracture during gas production using 3D synchrotron computed tomography
( Springer Verlag , 2019 , Conference Paper)During methane gas production from hydrate bearing sandy sediments, fine particles can migrate or clog the pores of sediments. Fines clogging induces a change in pressure gradient which affects the gas flow pattern and ... -
Prediction and sensitivity analysis of CNTs-modified asphalt's adhesion force using a radial basis neural network model
( Taylor and Francis Ltd. , 2019 , Article)The expected longer service life of modified asphalt can be jeopardized by different environmental factors, such as moisture, oxidation, etc. which affect the desired properties by altering the adhesive property. An insight ... -
Retarding aging of asphalt binders using antioxidant additives and copolymers
( Taylor and Francis Ltd. , 2019 , Article)The rheological properties of asphalt binders change with aging. Aging is accelerated at elevated temperatures due to binder oxidation, leading to fatigue cracking and eventually pavement failure under heavy and repeated ... -
Severity analysis of red-light-running-related crashes using structural equation modeling
( Taylor and Francis Inc. , 2019 , Article)The study investigated factors affecting the severity of red-light-running (RLR) -related crashes by means of crash records from the State of Florida (US). Previous studies have attempted to incorporate road, driver, and ... -
Reveal the hidden layer via entity embedding in traffic prediction
( Elsevier B.V. , 2019 , Conference Paper)The neural network-based models have been widely used in traffic prediction. They have improved accuracy and efficiency in traffic flow, speed, passenger flow, and delay. Many variables are considered to predict traffic ... -
Using pavements to generate electricity
( Elsevier B.V. , 2019 , Conference Paper)As part of developing a safe, efficient, and sustainable transportation infrastructure, health monitoring of pavements and bridges, as well as the monitoring of real-time roadway conditions for safety, have become increasingly ... -
A new thermal integrity method for pile anomaly detection
( DEStech Publications Inc. , 2019 , Conference Paper)Anomaly detection is a hot topic in pile construction which is a complex one due to the intrinsic nature of underground structures, such as limited accessibility, large depth and complex soil profile. Several traditional ... -
Characterization of Cellobiohydrolases from Schizophyllum commune KMJ820
( Springer , 2019 , Article)A novel cellobiohydrolase (CBH)-generating fungi have been isolated and categorized as Schizophyllum commune KMJ820 based on morphology and rDNA gene sequence. Cellulose powder was used as carbon source, the total enzyme ... -
A New Framework for Addressing High-level Decisions Related to Sustainable Transportation Development
( Taylor and Francis Ltd. , 2019 , Article)Stakeholders in the transportation industry have been concerned with sustainability. However, transportation decision makers have had difficulty in incorporating sustainability into transportation infrastructure decisions ... -
Tensile characterization of multi-ply fabric-reinforced cementitious matrix strengthening systems
( Wiley-Blackwell , 2019 , Article)Fabric reinforced cementitious matrix (FRCM) is a composite consisted of high-strength fibers impregnated in a cement-based mortar, and is commonly used for strengthening reinforced concrete and masonry structures. ... -
Microstructure investigation of seawater vs. Freshwater cement pastes
( ISEC Press , 2019 , Conference Paper)Recently, seawater has emerged as viable mixing water for concrete, especially in the case of non-reinforced concrete applications or with the use of non-corrosive reinforcement. Previous studies concerning seawater-mixed ... -
Modelling of Asphalt's Adhesive Behaviour Using Classification and Regression Tree (CART) Analysis
( Hindawi Limited , 2019 , Article)The modification by polymers and nanomaterials can significantly improve different properties of asphalt. However, during the service life, the oxidation affects the constituents of modified asphalt and subsequently results ... -
Revealing the hidden features in traffic prediction via entity embedding
( Springer London , 2019 , Article)Models based on neural networks (NN) have been used widely and successfully in traffic prediction resulting in improved accuracy and efficiency in traffic flow, speed, passenger flow, and delay. Input data include continuous ... -
