Abstract: A generalized predictive control with adaptive fuzzy estimator (GPC-AFE) is proposed for spacecraft. Model uncertainties and mismatch disturbances are considered in the process of controller design. For the attitude ...

Abstract: Gas injection displacement is a widely used technique to enhance the recovery of coal methane (CH4) or oil reservoirs. Additionally, this method plays a crucial role in effectively developing CH4 resources in a closed goaf. ...

Abstract: The perforated rib shear [Perfobond Leiste in German (PBL)] connector is a type of shear connector used in some steel–concrete composite bridges as a main load-transfer element between the concrete roadway and the supporting ...

Abstract: Excessive greenhouse gas emissions, primarily CO2, are a principal cause of global warming. China’s extensive abandoned mines and goafs present a unique opportunity for CO2 storage, offering a dual benefit of reducing ...

Abstract: This paper will present a comparative study of tsunami-induced forces on box girder and T-girder bridges, which will be based on component level analysis. Component level analysis can explain the overall loading behavior ...

Abstract: In this paper, the solitary wave forces on coastal bridge superstructures with box girders are discussed numerically. Although there are some empirical equations for wave forces on typical bridge superstructures, no relation ...
