We consider the Wright-Fisher model with exponential population growth and investigate effects of population growth on the shape of genealogy and the distributions of several test statistics of neutrality. In the limiting case as the population grows rapidly, the rapid-growth-limit genealogy is characterized. We obtained approximate expressions for expectations and variances of test statistics ...

The article presents pr ocess application of the rapi d prototyping (RP) for manufacturing of blades of aircraft turbine in monocrystallization and also directional crystallization of casting process. It is describing the method of modelling of the chosen elements of casting model kit with the usage of RP and RT system s. The article presents the analysis of additive rapid prototyping methods (...
