Cone crushers and jaw crushers both work by compression, reducing materials by squeezing them until they break apart. The benefit that cone crushers offer over jaw crushers is their ability to output a more cubical product similar to impact crushers. Cone crushers have traditionally been used as secondary and sometimes tertiary crushing ...

In graph theory, we can use specific types of graphs to model a wide variety of systems in the real world. An undirected graph (left) has edges with no directionality. On the contrary, a directed graph (center) has edges with specific orientations. Finally, a weighted graph (right) has numerical assignments to each edge.

Therefore, our main goal is to consider a new graph smoothing problem which we call ℓ 1-graph smoothing. It is similar to ℓ 2-graph smoothing except that we change the norm from the ℓ 2-norm to the ℓ 1-norm. Let G= (V,E) be a given graph with at least one edge. The ℓ 1-graph smoothing problem is the following optimization problem b(G ...
