RISA Fuzzy Random Chance-Constrained Programming for Water Distribution System under Uncertainty
Publisher: American Society of Civil Engineers
Abstract: In this paper, a model with integration of interval programming (IP), chance-constrained programming (CCP), and fuzzy random variables (FRVs), termed as an inexact fuzzy random chance-constrained programming (IFRCCP) model, ...
Application of Interval Type-2 Fuzzy Linear Programming to Chlorine Injection in a Water Distribution System
Publisher: American Society of Civil Engineers
Abstract: In this paper, an interval type-2 fuzzy linear programming (IT2FLP) model was proposed to deal with uncertainty in booster optimization of a water distribution system (WDS). The IT2FLP model was applied to two cases to ...
Multifrequency Back-Calculation of Pavement-Layer Moduli
Publisher: American Society of Civil Engineers
Abstract: This paper introduces a frequency-domain back-calculation program, BKGREEN, that can be used to determine the elastic modulus for each pavement layer. The pavement is modeled as a layered elastic system resting over a rigid ...
Hydraulic and Water Quality Reliability of Water Distribution System under Uncertain Conditions
Publisher: ASCE
Abstract: Reliability assessment plays a significant role in the planning, design, and operation of water distribution systems (WDS). Herein, pressure, flow, chlorine concentration, and water age are simulated by continuity, energy, ...

The Dynamic Response of the Hurricane Wind Field to Spiral Rainband Heating
Publisher: American Meteorological Society
Abstract: The response of the hurricane wind field to spiral rainband heating is examined by using a three-dimensional, nonhydrostatic, linear model of the vortex?anelastic equations. Diabatic heat sources, which are designed in ...
Do Gravity Waves Transport Angular Momentum away from Tropical Cyclones?
Publisher: American Meteorological Society
Abstract: Previous studies have suggested that gravity waves can transport a significantly large amount of angular momentum away from tropical cyclones, as much as 10% of the core angular momentum per hour. These previous studies ...
Spiral Rainbands in a Numerical Simulation of Hurricane Bill (2009). Part I: Structures and Comparisons to Observations
Publisher: American Meteorological Society
Abstract: his study examines spiral rainbands in a numerical simulation of Hurricane Bill (2009). This paper, the first part of the study, evaluates the structures of spiral rainbands and compares them to previous observations. Four ...
Spiral Rainbands in a Numerical Simulation of Hurricane Bill (2009). Part II: Propagation of Inner Rainbands
Publisher: American Meteorological Society
Abstract: his is the second part of a study that examines spiral rainbands in a numerical simulation of Hurricane Bill (2009). This paper evaluates whether the propagation of inner rainbands in the Hurricane Bill simulation is ...
Practical Issues for the Application of High-Performance Concrete to Highway Structures
Publisher: American Society of Civil Engineers
Abstract: In recent years, the advantages of high-performance concrete (HPC) have been well documented. Among others, these advantages include enhanced design flexibility and improved durability performance that results in reduced ...
