RISPreliminary Aerodynamic Design Strategy for Prop-Rotors Based on Multifidelity Methods
Publisher: ASCE
Abstract: A design strategy to provide suitable baseline prop-rotors for sophisticated applications is presented. Unlike those approaches aimed at improving the aerodynamic performance of an already refined blade by high-fidelity ...
Development and Validation of A C0–C7 FE Complex for Biomechanical Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the digitized geometrical data of the embalmed skull and vertebrae (C0–C7) of a 68-year old male cadaver were processed to develop a comprehensive, geometrically accurate, nonlinear ...
Intelligent Detection of Sealed Crack with 2D Asphalt Pavement Images
Publisher: American Society of Civil Engineers
Abstract: Accurately identifying sealed cracks on asphalt pavement surfaces is of significant importance to pavement management. This paper proposes an efficient semantic segmentation model called Parallel-TDNet for pixel-level ...
Impact Model Tests and Simplified Analysis for Flexible Pile-Supported Protective Structures Withstanding Vessel Collisions
Publisher: American Society of Civil Engineers
Abstract: Flexible pile-supported protective structures have been used extensively in the protection of bridge piers against vessel collisions. Their success is dependent on their ability to absorb impact energy through large ...
Measuring Route Travel Time Reliability in an Urban Rail Transit Network
Publisher: American Society of Civil Engineers
Abstract: Different from an urban road traffic system, an urban rail transit (URT) system operates on a relatively punctual schedule. However, as urban rail transit networks (URTNs) expand and become increasingly complex, the ...
Automated Detection of Pavement Manhole on Asphalt Pavements with an Improved YOLOX
Publisher: ASCE
Abstract: Accurate recognition and location of pavement manholes are of great significance for pavement maintenance. This paper proposes an improved You only look once X (YOLOX) for automated detection of manholes on asphalt pavements. ...
Pixel-Level Detection of Cracks Based on Loop Semantic Diffusion Integration
Publisher: American Society of Civil Engineers
Abstract: Precise crack identification on intricate asphalt pavements poses a significant challenge for intelligent pavement distress detection. This paper proposes the CellNet, a deep learning model designed to offer an effective ...
Dynamic Characteristics of Freezing–Thawing Aeolian Soil under Intermittent Cyclic Loading
Publisher: ASCE
Abstract: To investigate the dynamic characteristics of the soil in seasonally frozen areas under intermittent cyclic loading, a series of dynamic triaxial tests on frozen–thawed aeolian soil were conducted by using the global digital ...
Characterization of Volumetric Crack Rate and Its Influence on Unconfined Compressive Strength of Red Clay
Publisher: ASCE
Abstract: Desiccation cracking is a common phenomenon for red clay due to alternating wet and dry weathers. The presence of cracks definitely affects the strength of the soil; however, characterizing the development of desiccation ...
