Image Navigation for the FY2 Geosynchronous Meteorological Satellite
Publisher: American Meteorological Society
Abstract: An automatic image navigation algorithm for Feng Yun 2 (FY2) spin-stabilized geosynchronous meteorological satellites was determined at the National Satellite Meteorological Center (NSMC) of the China Meteorological ...
Use of the Failure Assessment Diagram to Evaluate the Safety of the Reactor Pressure Vessel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Analysis of multiple failure modes is the key element of the integrity evaluation of the nuclear reactor pressure vessel (RPV). While the simple singlecriterion failure code provides the guidance for structural integrity, ...
P-Δ Effect on Probabilistic Ductility Demand and Cumulative Dissipated Energy of Hysteretic System under Bidirectional Seismic Excitations
Publisher: American Society of Civil Engineers
Abstract: This study quantitatively investigates the influences of the
Stress Corrections After Necking Using a Two-Parameter Equation for the Radius of Curvature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Uniaxial tensile tests were conducted at room temperature, 100 °C and 150 °C, for obtaining necking-corrected stress–strain curves until fracture. The necking correction is based on specimen contours estimated from images ...
Life Cycle Performance Estimation and In Flight Health Monitoring for Gas Turbine Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A longterm gaspath fault diagnosis and its rapid prototype system are presented for online monitoring of a gas turbine engine. Toward this end, a nonlinear hybrid modelbased performance estimation and abnormal detection ...
Introducing the new generation of Chinese geostationary weather satellites – FengYun 4 (FY-4)
Publisher: American Meteorological Society
Abstract: hina is developing a new generation of geostationary meteorological satellites called FengYun-4 (FY-4) which is planned for launch beginning in the 2016 timeframe. Following upon the current FY-2 satellite series, FY-4 ...
Safety Evaluation of Branch Pipe in Hydropower Station Using Elastic Modulus Reduction Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The high pressure branch pipe in hydropower station (BPHS) is usually composed by different materials in different parts and has complicated geometric configurations. The accurate and efficient ...
Mesoscale Damage Detection and Surface Deterioration of Freeze–Thawed Concrete Cores Using 3D CT Scanning and Roughness Quantification
Publisher: ASCE
Abstract: The durability of bridges plays a vital role in their regular operation and transportation, particularly as service life increases. The ability of a bridge to reach its expected service life is closely linked to its ...
Effects of Environment and Fatigue on the Piezoresistivity of Carbon Nanotube–Cement Composite
Publisher: American Society of Civil Engineers
Abstract: The effects of environment and fatigue on the electrical resistance and piezoresistivity of the carbon nanotube–cement composite is investigated under a service environment using a four-probe method. The main influencing ...
