Strong Duality for a Multiple-Good Monopolist [PDF]

, 2017
We characterize optimal mechanisms for the multiple-good monopoly problem and provide a framework to find them. We show that a mechanism is optimal if and only if a measure $\mu$ derived from the buyer's type distribution satisfies certain stochastic ...

Effect of aging temperatures on the microstructural stability and mechanical properties of Super304H steel

Journal of Materials Research and Technology
Aging tests at 650 °C and 700 °C for up to 5000 h were performed on Super304H steel tubes. The microstructural evolution during aging was observed by optical microscopy (OM) and scanning electron microscopy (SEM).
