RISTo Outer Space on a Tether
Publisher: American Society of Civil Engineers
Abstract: The apogee of the Moon is 405,500 km and the perigee is 363,300 km. If there is a tethered satellite launched from SINUS MEDII on the Moon in the direction of the Earth, and the length of the tether is 355,154 km, then the ...
Modeling Springback of Metal-Polymer-Metal Laminates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Metal-polymer-metal laminate is an emerging material that has many potential applications. The laminated structure consists of two outer layers of sheet metal and a polymeric center core. The ...
Color Component–Based Road Feature Extraction from Airborne Lidar and Imaging Data Sets
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new framework of road feature extraction from color component–based data fusion of aerial imagery and lidar data. The proposed framework consists of six procedures: (1) removal of elevated objects ...
Improving Cost Estimates of Construction Projects Using Phased Cost Factors
Publisher: American Society of Civil Engineers
Abstract: Central to cost-based competition is the capability to accurately predict the cost of delivering a project. Most literature on cost estimation focuses on specific estimation methods as generic techniques and little attention ...
Effects of Silane-Coupling Agent Pretreatment on Basalt Fibers: Analyzing the Impact on Interfacial Properties and Road Performance
Publisher: ASCE
Abstract: Given the application characteristics and shortcomings of basalt fiber in road engineering, improvements to its reinforcing effect in asphalt mixture, such as reinforcing, toughening, and bridging, are needed. A silane-coupling ...
Macromodeling of SFRC Flexural Behavior and Impact of Fiber Characteristics on Flexural Behavior
Publisher: ASCE
Abstract: With advances in materials science, the performance of concrete materials has continued to improve, especially its compression strength. However, increases in compression strength often result in ductility decreases and ...
Contamination Source Identification in Water Distribution Systems Using an Adaptive Dynamic Optimization Procedure
Publisher: American Society of Civil Engineers
Abstract: Contamination source identification involves the characterization of the contaminant source based on observations that stream from a set of sensors in a water distribution system (WDS). The streaming data can be processed ...
Estimating Unfrozen Water Content in Frozen Soils Based on Soil Particle Distribution
Publisher: ASCE
Abstract: The unfrozen water content is a result of soil freezing, and its variation is closely related to temperature. To study the change in unfrozen water content, a relationship between water pressure and ice pressure is built ...
Multiparameter Sensitivity Analysis of Flexural–Tensile Property of Basalt Fiber–Reinforced Asphalt Mixture
Publisher: ASCE
Abstract: To evaluate the sensitivity of basalt fiber content, length-diameter ratio, and modulus to the flexural–tensile properties of fiber-reinforced asphalt mixture, the spatial random distribution of basalt fibers was realized ...
Observer-Based Output Feedback Tracking Control for Flexible Joint Space Manipulator with Output Constraints
Publisher: ASCE
Abstract: This paper proposed an observer-based output feedback tracking controller with output constraints for the rigid-link flexible-joint space manipulator system considering the dynamic damping caused by the torque change. By ...
