RISInfluence of Compressibility and Hardening on Cavitation
Publisher: American Society of Civil Engineers
Abstract: This paper examines the effect of material compressibility and material hardening on the phenomenon of internal rupture. Specifically, a bifurcation problem for a solid circular cylinder composed of a particular class of ...
Structures with Semiactive Variable Stiffness Single/Multiple Tuned Mass Dampers
Publisher: American Society of Civil Engineers
Abstract: This paper proposes application of single and multiple semiactive variable stiffness tuned mass dampers (STMD/SMTMD) for response control of multistory structures under several types of excitation. A new semiactive control ...
Use of Vehicle-Collected Data to Calculate Existing Roadway Geometry
Publisher: American Society of Civil Engineers
Abstract: The Federal Highway Administration has designated Highway Design Practices and Criteria as a high-priority research and development area. New design standards need to be developed to provide quantitative guidance on alignment ...
Experimental Study of Horizontal Barrier Formation by Colloidal Silica
Publisher: American Society of Civil Engineers
Abstract: Migration of non-aqueous-phase liquids (NAPLs) such as trichloroethylene or gasoline can be controlled by barrier systems. The research presented in this paper aims to form a horizontal layer by injecting gelling liquids ...
Closure to “Landfill Settlement with Decomposition and Gas Generation” by Ertan Durmusoglu, M. Yavuz Corapcioglu, and Kagan Tuncay
Publisher: American Society of Civil Engineers
Landfill Settlement with Decomposition and Gas Generation
Publisher: American Society of Civil Engineers
Abstract: A one-dimensional multiphase numerical model is developed to simulate the vertical settlement involving liquid and gas flows in a deformable (settling) municipal solid waste (MSW) landfill. MSW is represented by a chemical ...
Modeling of Settlement in Saturated and Unsaturated Municipal Landfills
Publisher: American Society of Civil Engineers
Abstract: Municipal solid waste (MSW) landfills are not only used to dispose the refuse in most economical way but also utilized as a viable land in today’s waste management strategy. Settlement prediction is an important issue in ...
Development and Testing of a Low NOx Hydrogen Combustion System for Heavy Duty Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Interest in hydrogen as a primary fuel stream in heavyduty gas turbine engines has increased as precombustion carbon capture and sequestration (CCS) has become a viable option for integrated gasification combined cycle ...
A Quantitative Comparison of Mechanical Blood Damage Parameters in Rotary Ventricular Assist Devices: Shear Stress, Exposure Time and Hemolysis Index
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ventricular assist devices (VADs) have already helped many patients with heart failure but have the potential to assist more patients if current problems with blood damage (hemolysis, platelet ...
Design Optimization of a Wearable Artificial Pump-Lung Device With Computational Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The heart-lung machine has commonly been used to replace the functions of both the heart and lungs during open heart surgeries or implemented as extracorporeal membrane oxygenation (ECMO) to ...
