Waveform and Frequency Spectrum Property of Ground-Penetrating Radar for Coarse-Grained Weak Sulfuric Acid Saline Soil Subgrade
Publisher: ASCE
Abstract: To accurately obtain the waveform and spectral characteristics of saline soil subgrade, on the basis of the provincial highway widening project of Ruoqiang-Weili county in Sinkiang, the field detection of coarse-grained ...
Sensitivity-Based Parameterization for Aerodynamic Shape Global Optimization
Publisher: ASCE
Abstract: For aerodynamic shape design using gradient-free searching algorithms, which can be applied more flexibly than gradient-based ones, computing costs increase dramatically with dimensionality. Rational design variables are ...
Effects of Microbial Carbonate Precipitation on Transport Properties of Fiber Cement Composites
Publisher: American Society of Civil Engineers
Abstract: Fibers have been used to improve the mechanical and physical properties of cement-based material since the late 1960s. The inclusion of high-dosage and high-aspect ratio microfibers, however, introduces new interfaces ...

Abstract: Fibers have been used to improve the mechanical and physical properties of cement-based material since the late 1960s. The inclusion of high-dosage and high-aspect ratio microfibers, however, introduces new interfaces ...
Compressive Stress–Strain Relationship of Concrete Containing Coarse Recycled Concrete Aggregate at Elevated Temperatures
Publisher: American Society of Civil Engineers
Abstract: This study investigated the compressive stress-strain curves of concrete produced with coarse recycled concrete aggregate (RCA) at temperatures in the range of 20°C to 800°C. Three concrete series were produced with coarse ...
Dynamic Model and Numerical Simulation for Synchronal Rotary Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The synchronal rotary compressor (SRC) has been developed to resolve high friction and severe wear that usually occur in conventional rotary compressors due to the high relative velocity between ...
Method for Improving the Natural Lateral-Directional Stability of Flying Wings
Publisher: American Society of Civil Engineers
Abstract: Poor lateral-directional flight quality is a critical technical problem in flying wing aircraft design. This paper proposes an approach to achieve lateral-directional dynamic stability of flying wing aircraft. This approach ...
Micromechanics-Based Optimization of Pigmentable Strain-Hardening Cementitious Composites
Publisher: American Society of Civil Engineers
Abstract: Architectural and decorative concrete (ADC) has become an enormously popular product for both building interiors and exteriors, combining an aesthetic finish with structural capabilities. Cracking and chipping of ADC product ...
Optimal Strategy for Enhancing Probabilistic Small-Signal Stability in a Power System with Wind-PV-Thermal Bundled Transmission
Publisher: American Society of Civil Engineers
Abstract: To address the challenges of integrating ever-increasing renewable energy generation such as wind power and photovoltaic (PV) to the power system concerned, the wind-PV-thermal-bundled (WPTB) transmission mode could be ...
