WebMost of powder compaction techniques lead to green compacts require sintering in order to gain high density and strength of the product. By using dynamic compaction systems, it is possible to attain a density very close to the theoretical density of the material without needs to sintering process [1–4 ]. WebUrban density refers to how many people live in a square mile of land. It is used as a variable in evaluating how livable a city design is. The optimal urban density for compact cities is high enough to keep residents close to community amenities but low enough to allow residents access to green spaces, reasonable privacy, and acceptable views.
