Evaluation of Transit Signal Priority Implementation for Bus Transit along a Major Arterial Using Microsimulation
( Elsevier B.V. , 2018 , Conference Paper)Transit Signal Priority (TSP) provides preferential treatment for public transit vehicles at signalized intersections when implemented. TSP is usually provided by interrupting the typical signal timings and extending the ... -
Evaluation of ultrafiltration and multimedia filtration as pretreatmeprocess for forward osmosis
( Desalination Publications , 2020 , Article)In order to reduce scaling in a multistage flash (MSF) desalination plant, the brine reject can be diluted using forward osmosis (FO) before recycling. In this FO process, the brine is used as the draw solution (DS) and ... -
Evaluation of Waste Engine Oil-Rejuvenated Asphalt Concrete Mixtures with High RAP Content
( Hindawi Limited , 2018 , Article)The use of large proportions of reclaimed asphalt pavement is necessary to meet the increasing demand for road construction materials in a sustainable way. One of the challenges of using a greater percentage of reclaimed ... -
Evidential Reasoning–Based Condition Assessment Model for Offshore Gas Pipelines
( American Society of Civil Engineers (ASCE) , 2016 , Article)Condition assessment of oil and gas pipelines is a significant component in pipeline operations and maintenance. Such assessments are used to ensure better decisions for repair and/or replacement to reduce pipelines’ failure ... -
Examining engineering students' perceptions of learner agency enactment in problem- and project-based learning using Q methodology
( John Wiley and Sons Inc , 2022 , Article)Background: Few studies have reported how students enact learner agency in a team setting or examined what elements of team settings students perceive as more supportive of their learning in problem- and project-based ... -
Experiences with licensing by autistic drivers: An exploratory study
( Elsevier B.V. , 2022 , Article)Autistic individuals obtain their driver's licenses significantly less or significantly later than non-autistic peers. In the past, research has been done on what problems autistic individuals experience when (learning to) ... -
