Mixed-Integer Chance-Constrained Models for Ground-Water Remediation
Publisher: American Society of Civil Engineers
Abstract: Ground-water remediation optimization models were formulated using a statistical optimization methodology, chance-constrained programming (CCP), to account for uncertainty in the coefficients of the models. Several models ...
Tribological Properties of Hot-Pressed SrSO4 Ceramic at Elevated Temperatures in Dry Sliding Against Alumina Ball
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: SrSO4 ceramic was prepared by hot-pressed sintering and its friction behavior was investigated against the Al2O3 ball under the dry sliding condition from room temperature to 800 °C. From room temperature to 400 °C, the ...
On the Influence of Lubricant Supply Conditions and Bearing Configuration to the Performance of (Semi) Floating Ring Bearing Systems for Turbochargers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engine oil-lubricated (semi) floating ring bearing ((S)FRB) systems in passenger vehicle turbochargers (TC) operate at temperatures well above ambient and must withstand large temperature gradients that can lead to severe ...
Tribological Properties of Spark Plasma Sintered NiCr–Cr2AlC Composites at Elevated Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, layered ternary Cr2AlC powders with high purity and a size of 0.5–1 μm were synthesized by solid-state reaction method. NiCr–Cr2AlC composites have been prepared by spark plasma sintering (SPS) process. The ...
