Effect of corrosion damage on the flexural performance of RC beams strengthened with FRCM composites
( Elsevier Ltd , 2017 , Article)This paper reports on the flexural behavior of corrosion-damaged reinforced concrete (RC) beams strengthened with different fabric-reinforced cementitious matrix (FRCM) composites. Three groups of beams were subjected to ... -
Effect of ageing on asphalt binders in the State of Qatar: a case study
( Taylor and Francis Ltd. , 2017 , Article)Ageing of asphalt binders has a significant impact on the rheological properties of asphalt binders and thus affects the performance of asphalt pavements. The rate of binder ageing is accelerated at high temperatures. This ... -
Cost based Value Stream Mapping as a sustainable construction tool for undergraound pipeline construction projects
( MDPI AG , 2017 , Article)This paper deals with application of Value Stream Mapping (VSM) as a sustainable construction tool on a real construction project of installation of underground pipelines. VSM was adapted to reduce the high percentage of ... -
Sustainable riverscape preservation strategy framework using goal-oriented method: Case of historical heritage cities in Malaysia
( Elsevier B.V. , 2017 , Article)Rapid development and transformation are the main causes for declining urban natural landscapes as well as its physical and environmental qualities. Currently, rehabilitation and preservation actions cause tough pressures ... -
Modeling and Parametric Study of the Reanchorage of Ruptured Tendons in Bonded Posttensioned Concrete
( American Society of Civil Engineers (ASCE) , 2017 , Article)The contribution of ruptured tendons to the residual strength of bonded posttensioned concrete structures is currently assessed based on pretensioned concrete bond models. However, this approach is inaccurate due to the ... -
Synthesis and characterization of cobalt hydroxide carbonate nanostructures
( Royal Society of Chemistry , 2017 , Article)Battery-type electrodes of three-dimensional (3D) hierarchical cobalt hydroxide carbonate arrays on Ni foam were fabricated using a hydrothermal method for use in supercapacitors. X-ray diffraction analysis, scanning ... -
Temporal variation in walking behavior: An empirical study
( Elsevier Ltd , 2017 , Article)This study provides a baseline for understanding the variation in walking behavior with respect to seasonal conditions in a hot weather country in the Arabian Gulf region. A busy neighborhood with different land-use patterns ... -
Ground-borne vibrations due to railway traffic in urbanized areas: A numerical study about traffic in trench cross-sections
( National Technical University of Athens , 2017 , Conference)Modern cities require efficient mass transportation systems like subway and railway networks. Due to the lack of available space and also due to environmental concerns, it is usually preferable to use the underground space ... -
Reveal the hidden layer via entity embedding in traffic prediction
( Elsevier B.V. , 2019 , Conference)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)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 ... -
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 ... -
Gas driven fracture during gas production using 3D synchrotron computed tomography
( Springer Verlag , 2019 , Conference)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 ... -
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 thermal integrity method for pile anomaly detection
( DEStech Publications Inc. , 2019 , Conference)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 ... -
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 ... -
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 ... -
Tensile characterization of multi-ply fabric-reinforced cementitious matrix strengthening systems
