RISTwo-Dimensional Visual Tracking in Construction Scenarios: A Comparative Study
Publisher: American Society of Civil Engineers
Abstract: The tracking of construction resources (e.g., workforce and equipment) in videos, i.e., two-dimensional (2D) visual tracking, has gained significant interest in construction industries. Many studies have relied ...
Novel Nanocomposite Fiber-Laden Viscoelastic Fracturing Fluid for Coal Bed Methane Reservoir Stimulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As coal has strong adsorption characteristics and well-developed natural fracture systems, an improper choice of fracturing fluid can result in significant challenges for coal bed methane exploitation, including damage to ...
A Numerical Study of the Contact Mechanics and Sub-Surface Stress Effects Experienced Over a Range of Machined Surface Coatings in Rough Surface Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper employs a rough-surface numerical elastic contact method designed to analyze Hertzian elastic contact effects of surface coatings. In particular the paper explores the differences in ...
Investigation on a Type of Flow Control to Weaken Unsteady Separated Flows by Unsteady Excitation in Axial Flow Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By solving unsteady Reynolds-averaged Navier-Stokes equations discretized by a high-order scheme, the results showed that the disordered unsteady separated flow could be effectively controlled by ...
Breakage Characteristics and Crushing Mechanism of Cement Materials Using Point-Loading Tests and the Discrete-Element Method
Publisher: American Society of Civil Engineers
Abstract: A point-loading device was used to research the breakage characteristics of single particles and to study their crushing mechanism. A series of point-loading tests were completed on the basis of cement ellipsoid particles ...
Analysis of Seismic Active Earth Pressure on Retaining Walls Based on Pseudo-dynamic Method
Publisher: American Society of Civil Engineers
Abstract: To examine the seismic active pressure on retaining walls, the pseudo-dynamic method is adopted in deducing the formulas of seismic active earth pressure. The critical rupture angle is analytically solved on the basis of ...
Modeling and Cycle Parameter Matching of a High-Speed Variable Cycle Turbofan-Ramjet Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Variable cycle turbofan-ramjet (VCTR) engine is a promising propulsion system candidate for future Mach 4+ vehicles. Compared with conventional turbine engines, the VCTR engine has a higher thrust-to-weight ratio, a smaller ...
Analytical Solutions to the Axisymmetrical Consolidation of Unsaturated Soils
Publisher: American Society of Civil Engineers
Abstract: In this study, analytical solutions are presented for the axisymmetrical consolidation of an unsaturated soil stratum on the basis of Fredlund and Hasan’s one-dimensional consolidation theory. Two different loading conditions, ...
Curing-Induced Debonding and Its Influence on Strength of Adhesively Bonded Joints of Dissimilar Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Adhesive bonding is thought to be a suitable method for joining dissimilar materials, such as aluminum to steel in multimaterial car-body manufacturing, but when it is combined with other joining methods, such as spot ...
Experimental Test of Properties of KCl–MgCl2 Eutectic Molten Salt for Heat Transfer and Thermal Storage Fluid in Concentrated Solar Power Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The eutectic mixture of MgCl2–KCl molten salt is a high temperature heat transfer and thermal storage fluid able to be used at temperatures up to 800 °C in concentrating solar thermal power systems. The molten salt ...
