Software configuration management (SCM) is a key element of the software development process. A number of new configuration management techniques in commercial SCM tools and environments with SCM capabilities have been observed. This report illustrates some of the advances in SCM concepts by example of a particular commercial system: the Sun Network Software Environment (NSE). NSE embodies a tr...

In this work, the shaft furnace reactor of the MIDREX® process is simulated. This is a counter current gas-solid reactor, which transforms iron ore pellets into sponge iron. Simultaneous mass and energy balance along the reactor leads to a set of ordinary differential equation with two points boundary conditions. The iron ore reduction kinetics was modelated with the unreacted shrinking core mo...
