RISDevelopment of Sketch Based 3 D Modeling System for Rapid Generation and Evaluation of Automotive Seat Shape Using Reference Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Seat style designers transform their ideas into 3D forms using creative, iterative modeling processes to quickly evolve their designs from concept to reality, while refining the design details of the seat shape. Although ...
Investigation of a Bridge Pier Scour Prediction Model for Safe Design and Inspection
Publisher: American Society of Civil Engineers
Abstract: A novel bridge scour estimation approach that comprises advantages of both empirical and data-driven models is developed here. Results from the new approach are compared with existing approaches. Two field datasets from ...
Dynamic Modeling of Directional Drillstring: A Linearized Model Considering Well Profile
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Drillstring vibration can cause fatigue failure of the drill pipe, premature wear of the bit, and a decreased drilling efficiency; therefore, it is important to accurately model the drillstring and bottomhole assembly (BHA) ...
An Analysis of Mixed Lubrication in Chemical Mechanical Polishing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure and shear flow factors (Patir and Cheng, 1978) were used to take into account the roughness of the pad surface in the modeling of the interfacial fluid pressure during chemical ...
Experimental Investigation of System-Identification-Based Damage Assessment on Structures
Publisher: American Society of Civil Engineers
Abstract: Damage assessment algorithms based on the system identification (SI) method are examined through laboratory experiments. The SI method considered herein identifies structural parameters in a finite-element model by minimizing ...
Statistical Damage Assessment of Framed Structures from Static Responses
Publisher: American Society of Civil Engineers
Abstract: This paper presents a damage assessment algorithm for framed structures based on a system identification scheme with a regularization technique. The regularization technique is introduced to alleviate the ill-posedness of ...
Isolation System for Vibration Control of Stay Cables
Publisher: American Society of Civil Engineers
Abstract: Rain-wind induced cable vibration can cause serious problems in cable-stayed bridges. Externally attached dampers have been used to provide an effective means to suppress the vibration of relatively short stay cables. For ...
Developing and Evaluating a Classification Model for Construction Defect Control: A Text Mining and Ensemble Learning Approach
Publisher: American Society of Civil Engineers
Abstract: In the construction industry, customer satisfaction is of paramount importance, as it significantly impacts company success and reputation. In Korea’s competitive apartment market, customer satisfaction—particularly feedback ...
Pad Soaking Effect on Interfacial Fluid Pressure Measurements During CMP
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Prior work has shown that there exist a sub-ambient fluid pressure at the interface between a rigid flat and the polishing pad during chemical mechanical polishing (CMP). This sub-ambient fluid ...
Tilt and Interfacial Fluid Pressure Measurements of a Disk Sliding on a Polymeric Pad
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous experimental work has shown that negative fluid pressure does develop at the disk/pad interface during chemical mechanical polishing. However, these studies dealt with one-dimensional ...
