RISElemental Composition and Source Apportionment of Suspended Particulate Matters and Health Risk Assessment in Mining and Nonmining Areas of Odisha, India
Publisher: American Society of Civil Engineers
Abstract: Atmospheric particulate matter was sampled synchronously during a monitoring campaign from January–December 2010 in mining and nonmining areas in Odisha, India. In this study, 14 elements were observed in suspended particulate ...
A Car-Following Model Considering Driver’s Instantaneous Reaction Delay in Nonlane-Based Traffic Environments
Publisher: ASCE
Abstract: Reaction delay is an indispensable factor in the operation and control process of drivers in a car-following scenario. Utilizing trajectory data obtained from an instrumented vehicle, this paper proposes a data-driven ...
Planning for Better Skywalk Systems Using Perception of Pedestrians: Case Study of Mumbai, India
Publisher: ASCE
Abstract: The aim of the current study was to identify the critical factors influencing the use of pedestrian skywalk facilities in an Indian context. An interviewer-administered questionnaire survey was conducted to understand the ...
Design of Structures With Intermediate Filters
Publisher: American Society of Civil Engineers
Abstract: Until now no solution was available to determine the effect of plane drainage located anywhere between two end cutoffs of a flat floor founded on permeable soil of finite depth. An exact solution has been obtained using ...
Flux-Difference Splitting Schemes for 2D Flood Flows
Publisher: American Society of Civil Engineers
Abstract: Two numerical models for 2D flood flows are presented. One model is first-order accurate and another is second-order accurate. Roe's numerical flux is used to develop the first-order accurate model, while second-order ...
First- and Second-Order Flux Difference Splitting Schemes for Dam-Break Problem
Publisher: American Society of Civil Engineers
Abstract: The first-order flux difference splitting scheme and its second-order extensions are investigated for their applicability to dam-break problems. Roe's first-order explicit scheme is first formulated using an approximate ...
Modeling Unsteady Open‐Channel Flows—Modification to Beam and Warming Scheme
Publisher: American Society of Civil Engineers
Abstract: A modification to the well‐known Beam and Warming implicit scheme is proposed and is applied to one‐dimensional unsteady free‐surface flows. The proposed modification is based on the concept of conservative splitting of ...
A Hybrid Response Surface Methodology and Multi-Criteria Decision Making Model to Investigate the Performance and Emission Characteristics of a Diesel Engine Fueled With Phenolic Antioxidant Additive and Biodiesel Blends
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Overconsumption of fossil fuels has accelerated global warming and raised environmental air pollution levels. Recent studies have looked into the potential use of alternative, environmentally friendly fuels for diesel ...
A Sustainable Response Surface Methodology and Analytic Hierarchy Process–Weighted Aggregated Sum Product Assessment Model to Evaluate Performance and Emissions Characteristics of Diesel Engine Using Clove Oil Biodiesel Blend
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Replacing diesel with biodiesel generally results in a decrease in exhaust emissions like carbon monoxide, hydrocarbon, particulate matter, and carbon dioxide. However, nitrogen oxide emissions show increasing trends. On ...
Optimum Location of Drains in Concrete Dams
Publisher: American Society of Civil Engineers
Abstract: Hydrostatic pressures from reservoir and tail water act on the dam and occur within the dam and foundation as internal pressures in the pores, cracks, joints, and seams. Measurements in existing dams confirm that uplift ...
