RISAdaptive Output Feedback Control of Spacecraft Formation Flying Using Chebyshev Neural Networks
Publisher: American Society of Civil Engineers
Abstract: This paper proposes two adaptive neural controllers, termed adaptive NN controller-I and adaptive NN controller-II, for the output feedback control of spacecraft formation flying in the presence of structured and unstructured ...
Performance Evaluation of RAP Concrete in Aggressive Environment
Publisher: American Society of Civil Engineers
Abstract: In this study, the feasibility of coarse (RC) and fine (RF) reclaimed asphalt pavement (RAP) inclusive concrete for sulfuric acid and hydrochloric acid environments is assessed. Moreover, the efficacy of mineral admixtures ...
Cost Models for Preliminary Economic Evaluation of Sprinkler Irrigation Systems
Publisher: American Society of Civil Engineers
Abstract: Cost models that provide a preliminary evaluation of the economic feasibility of portable pipe, traveling gun, and center‐pivot irrigation systems on a site‐specific basis are presented. The models require limited input ...
Performance of Fine RAP Concrete Containing Flyash, Silica Fume, and Bagasse Ash
Publisher: American Society of Civil Engineers
Abstract: In the present study, the adverse effect of dust on the properties of concrete containing 75% fine reclaimed asphalt pavement (RAP) (75F) (obtained using an uncontrolled milling technique) is minimized by using higher doses ...
On Predicting Nucleation of Microcracks Due to Slip-Twin Interactions at Grain Boundaries in Duplex Near γ-TiAl
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: (2003, “ A Factor to Predict Microcrack Nucleation at Gamma-Gamma Grain Boundaries in TiAl,” Scr. Mater., 49(2), 149–154) proposed a relationship for predicting crack initiation in γ-TiAl in a ...
