RISPerspective: The Experimentalist and the Problem of Turbulence in the Age of Supercomputers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the rising capabilities of computational fluid mechanics (CFD), the role of the experimentalist in solving the problem of turbulence has come under serious question. However, after much ...
Supply Chain Performance Evaluation With Rough Two-Stage Data Envelopment Analysis Model: Noncooperative Stackelberg Game Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rapidly changing environment has affected organizations' ability to maintain viability. As a result, various criteria and uncertain situations in a complex environment encounter problems when using the traditional performance ...
Satellite Neuro-PD Three-Axis Stabilization Based on Three Reaction Wheels
Publisher: American Society of Civil Engineers
Abstract: In this paper, a neuro-proportional derivative (PD) method is presented to stabilize a satellite with respect to the gravity gradient. Three reaction wheels are employed to produce the necessary torque in the axes of the ...
Experimental and Numerical Study of Micropiles to Reinforce High Railway Embankments
Publisher: American Society of Civil Engineers
Abstract: The construction of railway embankments on loose beds using reinforcing elements results in a modification of the embankments slope, which significantly reduces the amount of earthworks. In addition, reinforcement of both ...
Optical and Thermal Simulations of Photovoltaic Modules With and Without Sun Tracking System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The experimental method is extensively used to determine the temperature of a photovoltaic (PV) module at different hours of a day. In this method, the module temperature is measured using a temperature sensor mounted on ...
Effect of Atomization Method on the Morphology of Spray-Generated Particles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Effect of various atomization methods and solute concentration on the morphology of spray dried magnesium sulphate particles is investigated. Four types of atomizers are characterized and tested ...
Intrinsic Relation between Soil Water Retention and Cation Exchange Capacity
Publisher: American Society of Civil Engineers
Quantification of Exchangeable Cations Using Soil Water Retention Curve
Publisher: American Society of Civil Engineers
Abstract: The amount of exchangeable cation (EC) and cation types play important roles in fundamental soil behavior such as mechanical, hydraulic, chemical transport, and soil water retention (SWR). A methodology is proposed for the ...
Mechanisms for Soil-Water Retention and Hysteresis at High Suction Range
Publisher: American Society of Civil Engineers
Abstract: Conventional conceptual mechanisms for the hysteresis of soil-water retention are the ink-bottle pore neck and the solid–liquid–air-contact angle. However, these mechanisms fail to explain hydraulic hysteresis for matric ...
Determination of Cation Exchange Capacity from Soil Water Retention Curve
Publisher: American Society of Civil Engineers
Abstract: Cation exchange capacity (CEC) has a significant influence on the physical and chemical behavior of soil. Quantification of the CEC is an essential yet challenging task. A new methodology for the determination of the CECs ...
