RISA Novel Input Ripple Current Suppressing Topology Configuration and Controller for Residential Fuel Cell Power Conditioning System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Proton exchange membrane fuel cell (PEMFC)’s power conditioning system (PCS) for residential application always contains two stage converter configuration of the dc-dc converter and the power grid ...
Mapping Extent of Floods: What We Have Learned and How We Can Do Better
Publisher: American Society of Civil Engineers
Abstract: Much attention has been given to mapping the extent of a flood by using optical, radar, digital elevation model (DEM), and river gauge data. The mapped extent is often supported and verified by ground observations. The ...
Comparison of Light Detection and Ranging and National Elevation Dataset Digital Elevation Model on Floodplains of North Carolina
Publisher: American Society of Civil Engineers
Abstract: USGS national elevation dataset (NED) digital elevation model (DEM) data and four sets of light detection and ranging (LIDAR) DEMs were compared for Pitt County, North Carolina. The NED DEM has a spatial resolution of
Robust Station-Keeping Control of Sun-Earth/Moon Libration Point Orbits Using Electric Propulsion
Publisher: American Society of Civil Engineers
Abstract: A novel strategy combining an extended state observer (ESO) and a backstepping sliding mode (BSM) controller is proposed for station-keeping of unstable collinear libration point orbits (LPOs) in the Sun-Earth/Moon system. ...
Strength Behavior of Temperature-Dependent MICP-Treated Soil
Publisher: ASCE
Abstract: Microbially induced carbonate precipitation (MICP) is a novel soil-strengthening technique that involves a biogeochemical process. Temperature plays a crucial role in influencing the biological and chemical processes ...
Effect of Temperature on Strength and Elastic Modulus of High-Strength Steel
Publisher: American Society of Civil Engineers
Abstract: This paper presents the effect of temperature on the mechanical properties of high-strength alloy structural Q460 steel. The strength and stiffness properties of steel degrade with temperature and this deterioration has ...
Evaluation of Properties of Concrete Incorporating Fly Ash or Slag Using a Hydration Model
Publisher: American Society of Civil Engineers
Abstract: Granulated slag from metal industries and fly ash from the combustion of coal are industrial by-products that have been used widely as mineral admixtures in normal and high-strength concrete. Because of the reaction between ...
Vibration Reduction of Bucket Foundation Platform with Fixed Ice-Breaking Cone in the Bohai Sea
Publisher: American Society of Civil Engineers
Abstract: The bucket foundation platform is an important engineering design alternative in oil/gas field developments in the Bohai Sea because of its economic and structural characteristics. Severe ice-induced vibrations were observed ...
Study of the Suitability of Existing Deterioration Models for Water Mains
Publisher: American Society of Civil Engineers
Abstract: Deterioration of water mains causes serious problems in major urban communities worldwide. This paper presents the findings of a recent study conducted on pipe-break data in an effort to identify and categorize the key ...
Prediction Models for Annual Break Rates of Water Mains
Publisher: American Society of Civil Engineers
Abstract: Annual break rates are often used by municipalities as one of the most important criteria in rating the condition of water mains. This paper presents the development of deterioration models that predict the annual break ...
