Abstract: A boundary-layer survey has been conducted on a rough plate consisting of uniform spherical particles arranged in a random and compact fashion. Strong turbulent mixing was observed in a region ...

Abstract: It is a general practice to treat the flow in alluvial channels in two scales: the microscale over bed materials (sand grains), and the macroscale over bed forms. Contrary to common thinking, the flow over bed materials ...

Abstract: Results from investigations on airflows over sand were compiled to show two interesting characteristics of these flows. The minimum friction velocity for the inception of wind erosion is shown to be 16 cm/s. The tendency ...

Abstract: Industry Foundation Classes (IFC) is widely accepted as the future of building information modeling (BIM) to take on the challenge of BIM interoperability and enable its support of various automation tasks. However, it is ...

Abstract: Acrylic emulsion polymer–modified mortar (AEPM) is widely used for repairing and maintaining the surface of existing concrete structures. In this study, the durability of AEPM was improved by using slag and fly ash. ...

Abstract: The vertical displacement of pavement concrete slab end at the joint is prone to emerge in its long-term service. It would lead to the occurrence of the joint faulting and other diseases, bringing safety hazards to the ...

Abstract: Fully automated building code compliance checking (ACC) requires accurate information extraction from both building information models (BIMs) and building code chapters, and equally (if not more) importantly, a precise ...

Abstract: Drag reduction caused by ejecting additive solutions from a slot into a pure-water boundary layer on a flat plate has been systematically studied. Results include drag measurements for a plane ...
