Adaptive Variable Threshold Event-Triggered Control for Trajectory Tracking of Autonomous Underwater Vehicles with Actuator Saturation
Publisher: American Meteorological Society
Abstract: This article develops a novel event-triggered sliding mode control (ETSMC) approach with variable threshold to deal with trajectory tracking matters of autonomous underwater vehicles (AUVs) accompanied by actuator saturation ...
Development of Nailed Wood Joint Element in ABAQUS
Publisher: American Society of Civil Engineers
Abstract: Testing showed that the hysteretic behavior of nailed wood joints governs the response of many wood systems when subjected to lateral loadings. Unfortunately, commercially available software does not have the appropriate ...
Development of a Wood-Frame Shear Wall Model in ABAQUS
Publisher: American Society of Civil Engineers
Abstract: After modifications, the Bouc-Wen-Barber-Wen (BWBN) model was used in simulating the hysteretic behavior of wood light-frame shear walls. A complete shear wall model is composed of boundary framing members and two-diagonal ...
Geometrical Design and Investigation of a New Profile of the Three Screw Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new edge blunting method of the three screw pump rotor with an elliptic arc and equations of the rotor profile after edge blunting. Through comparisons of different ...
Shear Strength and Mesoscopic Characteristics of Basalt Fiber–Reinforced Loess after Dry–Wet Cycles
Publisher: ASCE
Abstract: Frequent dry–wet cycles induced uneven settlement and slope failure of transportation infrastructures in the Loess Plateau of China. Fiber reinforcement provides a method for solving these problems. In this study, a digital ...
Microscale Property Evaluation of the Interface between Cement Emulsified Asphalt and Aged Asphalt in Emulsified Asphalt Cold Recycled Mixture
Publisher: ASCE
Abstract: To study the microscale properties of the interface between cement emulsified asphalt and aged asphalt in the emulsified asphalt cold recycled mixture, the PeakForce quantitative nano mechanics (PF-QNM) technology of atomic ...
Disturbed State Concept–Based Model for the Uniaxial Strain-Softening Behavior of Fiber-Reinforced Soil
Publisher: ASCE
Abstract: A uniaxial strain-softening constitutive model for fiber-reinforced soils is developed based on the disturbed state concept (DSC). The response in the relatively intact state is assumed to satisfy the Duncan–Chang model ...
Variability Investigation of Reclaimed Asphalt Pavement Materials
Publisher: ASCE
Abstract: The maximum permissible content of reclaimed asphalt pavement (RAP) is restricted due to its negative effect on the stability of hot mix asphalt with RAP (HMA-RAP) performance. To address this problem, characteristics of ...
Morphology of Asphalt Mixture Rheological Master Curves
Publisher: American Society of Civil Engineers
Abstract: Most asphalt mixture rheology studies were limited to condition tests and condition-evaluation indices, which cannot describe the changes in mechanical properties along with changing external conditions. The full-tempera ...
