RISGround and Sieved Bio Ash versus Coal Fly Ash: Comparative Analysis of Pozzolanic Reactivity
Publisher: ASCE
Abstract: Due to the declining availability of coal fly ash, there is a need to identify alternative sources of supplementary cementitious materials (SCMs). This article presents an investigation on the reactivity of ground and ...
Analytical Solutions of ADE with Temporal Coefficients for Continuous Source in Infinite and Semi-Infinite Media
Publisher: American Society of Civil Engineers
Abstract: In the present technical note, two aspects commonly used to obtain the analytical solution of advection–diffusion equation (ADE) with time-dependent coefficients describing solute transport due to a continuous source in ...
Optimization of the Process Parameters for Hydrotreating Used Cooking Oil by the Taguchi Method and Fuzzy Logic
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydrotreating process is an alternate approach for producing diesel hydrocarbons from the biomass-based oils. In the present study, used cooking oil was selected for the hydrotreating process due to its high abundance. A ...
Impact of Mixed Convective and Radiative Heat Transfer in Spiral-Coiled Tubes
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Spiral-coiled tube heat exchangers (SCTHE) have higher heat transfer as compared to the conventional heat transfer devices and are extensively used to extract heat from exhaust gases in the chemical processing industries ...
Automated Constructibility Analysis of Work-Zone Traffic-Control Planning
Publisher: American Society of Civil Engineers
Abstract: Constructibility, in simple words, is the ability to construct effectively. This study involved the development of a prototype system to perform highway constructibility analysis of traffic-control planning (TCP). The ...
Design and Preliminary Validation of Grasp Assistive Device for an Industrial Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Carpal tunnel syndrome and tendonitis are two common upper extremity cumulative trauma disorders (CTD) related to repetitive and forceful activities in industrial environments. Reducing the muscular force during activities ...
A Framework for Assessing Models that Rank Highway-Rail Grade Crossings for Improvement
Publisher: American Society of Civil Engineers
Abstract: In the Midwest, three states in recent years have re-examined their grade crossing model. Illinois conducted a study that developed a new model, the expected accident frequency formula, using a nonlinear regression analysis ...
Using Advanced Inspection Technologies to Support Investments in Maintenance and Repair of Transportation Infrastructure Facilities
Publisher: American Society of Civil Engineers
Abstract: We present a statistically rigorous and computationally efficient framework that can exploit the extensive capabilities of advanced inspection technologies to support investment decisions in maintenance and repair of ...
One-Dimensional Pollutant’s Advective-Diffusive Transport from a Varying Pulse-Type Point Source through a Medium of Linear Heterogeneity
Publisher: American Society of Civil Engineers
Abstract: Analytical solutions of one-dimensional (1D) advection-diffusion equations (ADE) are obtained subject to an initially pollutant-free domain and varying pulse-type input conditions. The medium is considered heterogeneous ...
Effects of Solar Loading on Infrared Imaging of Subsurface Features in Concrete
Publisher: American Society of Civil Engineers
Abstract: This paper addresses the effect of solar loading on thermal imaging for the detection of subsurface deterioration in concrete bridge components. The deterioration of the concrete resulting from corrosion of embedded mild ...
