RISAnisotropy of Surface Morphology Characteristics of Rock Discontinuity and Its Evaluation Method
Publisher: ASCE
Abstract: The mechanical and hydraulic properties of rock discontinuity are anisotropic, and the main reason resides in the anisotropy of surface morphology. This study delved systematically into the anisotropic characteristics of ...
An Intelligent Control Method Based on Fuzzy Logic for a Robotic Testing System for the Human Spine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In previous biomechanical studies of the human spine, we implemented a hybrid controller to investigate load-displacement characteristics. We found that measurement errors in both position and ...
Explicit Non-linear Numerical Analysis of Dynamic Compaction
Publisher: American Society of Civil Engineers
Abstract: Dynamic compaction is an efficient ground improvement technique. The collision process of dynamic compaction (DC) was studied using nonlinear explicit dynamic finite element. In this study many characters were taken into ...
Predicting Gas Leakage in the Rotary Engine—Part II: Side Seals and Summary
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Wankel rotary engine offers a greater power density than piston engines, but higher fuel consumption and hydrocarbon emissions, in large part due to poor gas sealing. This paper presents a model for the deformable ...
Predicting Gas Leakage in the Rotary Engine—Part I: Apex and Corner Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Wankel rotary engine offers a greater power density than piston engines, but higher fuel consumption and higher hydrocarbon emissions, in large part due to poor gas sealing. This paper presents a modeling approach to ...
Eurasian Cold Air Outbreaks under Different Arctic Stratospheric Polar Vortex Strengths
Publisher: American Meteorological Society
Abstract: AbstractThis study analyzes the differences and similarities of Eurasian cold air outbreaks (CAOs) under the weak (CAOW), strong (CAOS), and neutral (CAON) stratospheric polar vortex states and examines the potential links ...
Uncertainty Analysis of the Dynamic Responses of a Transmission Tower-Line System Subjected to Cable Rupture
Publisher: ASCE
Abstract: Because transmission tower-line systems are always exposed to the natural environment, such structures are vulnerable to various meteorological conditions, and the rupture of a transmission line is a particularly serious ...
Experimental Study on the Performance of a Sand Filtration Method and Device by Using Natural Soils and Subsurface PVC Drainage Pipes
Publisher: ASCE
Abstract: Drip irrigation is an efficient water-saving irrigation technique. However, the clogging of emitters is a major problem for drip irrigation systems that adversely affects the uniformity of water distribution and lowers the ...
Optimizing Task Scheduling for Efficient and Ergonomic Human–Robot Collaboration in Construction Tasks
Publisher: American Society of Civil Engineers
Abstract: Abstract Human–robot collaboration (HRC) offers transformative potential in construction to
mitigate labor shortages and enhance productivity. Effective task scheduling between
human workers and robots is essential for ...
Contact Analysis of Regular Patterned Rough Surfaces in Magnetic Recording
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The contact of regular patterned rough surface in magnetic recording was analyzed to predict the contact area, meniscus force and permissible load under thin-film lubricated conditions. The contact ...
