Substitution of Ni for Zn on microstructure and mechanical properties of Mg–Gd–Y–Zn–Mn alloy
Journal of Magnesium and Alloys, 2017 This study analyzes the effect of substitution of Ni for Zn on microstructure and mechanical properties of Mg–Gd–Y–Zn–Mn alloy. Our results show that the volume fraction of Mg5(Gd, Y) and (Mg, Zn)3RE phase decreased and LPSO phase increased with more ...

Effect of heat treatment on LPSO morphology and mechanical properties of Mg–Zn–Y–Gd alloys
Journal of Magnesium and Alloys, 2020 The mechanical properties and microstructure were investigated under different Zn content and heat treatment conditions in a Mg–Zn–Y–Gd cast alloy. A part of the long period stacking order (LPSO) phases transformed to W-Mg3Zn3RE2 phases with an increase ...

Adaptive particle swarm optimization [PDF]
, 2009 An adaptive particle swarm optimization (APSO) that features better search efficiency than classical particle swarm optimization (PSO) is presented. More importantly, it can perform a global search over the entire search space with faster convergence ...

Indexation Of Unemployment Benefits To Previous Earnings, Employment And Wages [PDF]
In most OECD countries, unemployment benefits are tied to individual previous labor earnings. We study the progressivity of this indexation with regard to its effects on employment, output and wages in four equilibrinin models of the labor market keeping

Optimal Workfare in Unemployment Insurance [PDF]
Most workers are only partially insured against unemployment. One reason is that high unemployment compensation creates a free rider problem when monitoring of job search behavior is limited; people who do not seek employment (non-workers) may ...

(SUB-)Optimal entry fees [PDF]
, 2002 We extend Myerson's (1981) model by allowing for uncertainty about the number of bidders. In such extension the Revenue Equivalence Theorem still holds and the optimal allocation rule remains the same.
