RISOn the Distributions of Swamee
Publisher: American Society of Civil Engineers
Abstract: It is pointed out that the hydrological models introduced in recent papers by Swamee are contained by at least two families of distributions known since the 1940s. Some elementary statistical properties, history, and related ...
Discussion of “Sampling Techniques for Halphen Distributions” by S. El Adlouni and B. Bobée
Publisher: American Society of Civil Engineers
Development of Innovative Foundation Configuration for Tall Wind Turbines Inspired by Tree Root System
Publisher: ASCE
Abstract: This study presents a simplified analytical design and numerical modeling of the pile group foundation for a wind turbine tower on multilayered soil. The pile group foundation obtained from the analytical design is modified ...
Constrained Adjoint Based Aerodynamic Shape Optimization of a Single Stage Transonic Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper develops a discrete adjoint formulation for the constrained aerodynamic shape optimization in a multistage turbomachinery environment. The adjoint approach for viscous internal flow problems and the corresponding ...
Optimum Shape Design for Multirow Turbomachinery Configurations Using a Discrete Adjoint Approach and an Efficient Radial Basis Function Deformation Scheme for Complex Multiblock Grids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a framework for fully automatic gradientbased constrained aerodynamic shape optimization in a multirow turbomachinery environment. The concept of adjointbased gradient calculation is discussed and the ...
The Intrusion Depth of Density Currents Flowing into Stratified Water Bodies
Publisher: American Meteorological Society
Abstract: Theory and laboratory experiments are presented describing the depth at which a density current intrudes into a linearly stratified water column, as a function of the entrainment ratio E, the buoyancy flux in the dense ...
Design of Shallow Foundation considering Site-Specific Rainfall and Water Table Data: Theoretical Framework and Application
Publisher: American Society of Civil Engineers
Abstract: The increase of significant hydrological events, such as heavy rainfall and flooding, in recent years has adversely impacted the performance of many structures, particularly the foundations that transfer the superstructure ...
Stability and Deformation Responses of Earth Slopes Subjected to Multiple Natural and Manmade Hazards
Publisher: ASCE
Abstract: Multiple hazards such as rainfall, earthquake, and excavation may occur simultaneously, and the stability (factor of safety) and deformation (movement) behaviors must be investigated to prevent loss of life and properties. ...
New Soil-Water Characteristic Curve and Its Performance in the Finite-Element Simulation of Unsaturated Soils
Publisher: American Society of Civil Engineers
Abstract: Among the many constitutive equations, the moisture-suction relationship, also known as the soil-water characteristic curve (SWCC), is one of the important relationships needed for modeling the dynamics of unsaturated soils ...
Effect of Deformation-Induced Suction in the Behavior of Unsaturated Fine-Grained Soils Using Simplified Finite-Element Model
Publisher: American Society of Civil Engineers
Abstract: Matric suction is one of the important variables used to characterize the deformation behavior of unsaturated soil. The stress-strain relationship and the governing differential equations are the two elements in which ...
