RISInfluence of Strain History on Postliquefaction Deformation Characteristics of Sands
Publisher: American Society of Civil Engineers
Abstract: An experimental study aimed at improving the understanding of the role of maximum
cyclic strain during earthquake loading on the subsequent response of liquefied
sands is presented. ...
Homotopy Perturbation Method for Nonlinear Vibration Analysis of Functionally Graded Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the Homotopy perturbation method (HPM) is used to analysis the geometrically nonlinear vibrations of thin rectangular laminated functionally graded material (FGM) plates. The Von Karman's straindisplacement ...
Prediction Flutter Boundaries of Laminated Cylindrical Shells Using Scaling Laws
Publisher: American Society of Civil Engineers
Abstract: In this paper, the necessary scaling laws for flutter speeds of laminated cylindrical shells are developed using the similitude theory. To consider the effect of mode shape factor, the characteristic equation of the system ...
Copula-Based Performance Assessment of Online and Offline Detention Ponds for Urban Stormwater Management
Publisher: American Society of Civil Engineers
Abstract: Detention ponds are known as an efficient low-impact development (LID) strategy for reducing the negative impacts of urban floods. Their performance in flood peak attenuation is directly related to the size, location, and ...
Prediction of Elastic Modulus of Concrete Using Support Vector Committee Method
Publisher: American Society of Civil Engineers
Abstract: Knowledge about concrete properties is of utmost importance in engineering materials, and elastic modulus is one of concrete’s most important properties that is used in the calculation of deformation of structures. For ...
Calibration of Soil Model Parameters Using Particle Swarm Optimization
Publisher: American Society of Civil Engineers
Abstract: In this paper, a neuro-fuzzy model in conjunction with particle swarm optimization (PSO) are used for calibration of soil parameters used within a linear elastic-hardening plastic constitutive model with the Drucker-Prager ...
Investigation on the Effect of Data Imbalance on Prediction of Liquefaction
Publisher: American Society of Civil Engineers
Abstract: Data imbalance causes learning bias in class identification techniques. A major cause for limited success in the prediction of liquefaction potential by various pattern recognition techniques is because of a liquefaction ...

Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigated the feasibility of harvesting algae biomass using an original and novel method that uses low-grade waste heat with an integrated heat exchanger, evaporation tank, and reservoir system. Several ...
Stabilization of Biped Walking Robot Using the Energy Shaping Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The biped walking robot demonstrates a stable limit cycle on shallow slopes. In previous researches, this passive gait was shown to be sensitive to ground slope and initial conditions. In this ...
Intelligent Pump Operation and River Diversion Systems for Urban Storm Management
Publisher: American Society of Civil Engineers
Abstract: Large-scale networks of sewer pipes, control gates, and pump stations are the primary facilities of urban drainage systems for mitigating flood risks. During flooding periods, cooperation of pumps and control gates plays ...
