RISUltrafast Spectroscopy of Electron Phonon Coupling in Gold
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Transient reflectance of gold was measured using ultrafast spectroscopy by varying the wavelength of the probe laser beam in the visible range. Based on the band structure of gold, the influence of the probe beam wavelength ...
Seismic Analysis of a 500-kV Power Transformer of the Type Damaged in the 2008 Wenchuan Earthquake
Publisher: American Society of Civil Engineers
Abstract: As indispensable electric power equipment in substations, high-voltage power transformers have experienced severe damage in past earthquakes. This paper illustrates an earthquake-damaged 5-kV power transformer: all three ...
Review of Study of Long-term Deflection for Long Span Prestressed Concrete Box-girder Bridge
Publisher: American Society of Civil Engineers
Abstract: The long-term deflection of Long Span Prestressed Concrete Box-girder Bridge (LSPCBB) is getting more and more serious in terms of structure safety. And there are still many ambiguous reasons as to the cause of the deflection ...
Review of Computational Models and Methods for Predicting Ultimate Capacity of Uplift Piles with Uniform Cross Section
Publisher: American Society of Civil Engineers
Abstract: To improve the application of uplift piles, the calculation method for ultimate bearing capacity is analyzed to study the significant difference between the calculation and test values of bearing capacity. The computational ...
Exploratory Experimental Study on Fatigue Prestress Loss of Prestressed Concrete Beams
Publisher: American Society of Civil Engineers
Abstract: To study the fatigue prestress loss of prestressed concrete beams, four bonded post-tensioned bonded concrete simple supported beams were designed and constructed for constant-amplitude fatigue load displacement tests. ...
Analysis of Mode and Dynamic Stability for Wind Turbine Rotating Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For large-scale offshore wind turbine rotating blades (NREL 5MW), the theoretical model of vibration due to fluid-structure interaction (FSI) is established, and the basic equations for modal analysis are given. Based on ...
Prediction of the Postfire Flexural Capacity of RC Beam Using GA-BPNN Machine Learning
Publisher: ASCE
Abstract: To accurately predict the flexural capacity of postfire RC beams is imperative for fire safety design. In this paper, the residual flexural capacity of postfire RC beams is predicted based on a back-propagation (BP) neural ...
Simulation of Fluid Flow in Fractured Rocks Based on the Discrete Fracture Network Model Optimized by Measured Information
Publisher: American Society of Civil Engineers
Abstract: The fluid flow of Jijicao block in Beishan, one of the main candidate sites for a Chinese high-level radioactive waste (HLW) repository, was studied by a simulation on the basis of the discrete fracture network (DFN) model ...
Local and Remote Impacts of Aerosol Species on Indian Summer Monsoon Rainfall in a GCM
Publisher: American Meteorological Society
Abstract: he HadGEM2 AGCM is used to determine the most important anthropogenic aerosols in the Indian monsoon using experiments in which observed trends in individual aerosol species are imposed. Sulfur dioxide (SD) emissions are ...
Contribution of Tropical Cyclones to Atmospheric Moisture Transport and Rainfall over East Asia
Publisher: American Meteorological Society
Abstract: AbstractThe coastal region of East Asia (EA) is one of the regions with the most frequent impacts from tropical cyclones (TCs). In this study, rainfall and moisture transports related to TCs are measured over EA, and the ...
