RISStudy of Factors Influencing Quality of Life through Matches between Demand and Satisfaction of Cultural Services in Urban Parks
Publisher: ASCE
Abstract: Quality of life is increasingly a concern for city dwellers, and it is widely accepted that it can bring benefits to urban developments. As the only natural element in modern cities, urban parks can provide cultural services ...
Degradation of p-Nitrophenol by Nanoscale Zero-Valent Iron Produced by Microwave-Assisted Ball Milling
Publisher: American Society of Civil Engineers
Abstract: The applicability of microwave-assisted ball milling for the treatment of p-nitrophenol (PNP) was investigated in this study. The degradation process of PNP was studied by using UV-vis (ultraviolet-visible) spectra, total ...
Numerical Modeling Approach for Steel Catenary Riser Behavior at Touchdown Zone
Publisher: ASCE
Abstract: This paper introduces a new numerical approach in the analysis of the dynamic interaction between the steel catenary riser (SCR) and seabed in the vicinity of the touchdown zone (TDZ). The interaction between the SCR and ...
Phase-Locked Impact of the 11-Year Solar Cycle on Tropical Pacific Decadal Variability
Publisher: American Meteorological Society
Abstract: As an important external forcing, the effect of the 11-yr solar cycle on the tropical Pacific decadal variability is an interesting question. Here, we systematically investigate the phase-locking of the atmosphere and ocean ...
Hydrodynamics of Gravity Currents Down a Ramp in Linearly Stratified Environments
Publisher: American Society of Civil Engineers
Abstract: Gravity currents play an important role in many aspects of natural processes and engineering practice. This paper presents a systematic lock-exchange experimental study to investigate the influence of linearly stratified ...
Sampling-Based Stochastic Sensitivity Analysis Using Score Functions for RBDO Problems With Correlated Random Variables
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents a methodology for computing stochastic sensitivities with respect to the design variables, which are the mean values of the input correlated random variables. Assuming that ...
Capacity of Caissons in Dense Sand under Combined Loading
Publisher: ASCE
Abstract: This paper presents the development of an improved plasticity model to define the combined vertical and horizontal capacity of suction caisson in sand under low vertical loads, conditions relevant for foundations of offshore ...
Performance of Parallel, Interdigitated, and Serpentine Flow Field PEM Fuel Cells with Straight or Wavelike Channels
Publisher: ASCE
Abstract: This work used a three-dimensional, two-phase, and nonisothermal model to compare performances of proton exchange membrane (PEM) fuel cells with a parallel, interdigitated, or serpentine flow field when wavelike gas channels ...
A Practical Numerical Model of Embedded Mooring Chains in Clayey Soils
Publisher: American Society of Civil Engineers
Abstract: Interactions between mooring chains and the seabed are crucial in the estimation of the capacities of mooring anchors for floating facilities in deep water. This paper presents a computationally efficient numerical approach ...
Transformation Mechanism of Organic Matter in the Treatment of Petroleum-Based Drilling Cuttings by the Hammermill Thermal Desorption Cutting Treatment System
Publisher: American Society of Civil Engineers
Abstract: Petroleum-based drilling cuttings (PBDCs), as hazardous waste, are characterized by high petroleum pollutant contents and complex compositions and must be properly treated. Their treatment by a hammermill thermal desorption ...
