Social networks have surpassed their intermediary role and become gatekeepers of online content traffic. This transformation has favored the spread information disorders. The situation is especially alarming in Spain, where 57% Spaniards at some moment believed false news. Since 2016, First Draft promoted several collaborative verification projects that brought together newsrooms to fact-check ...

In industrial engineering, transportation planning, vehicle routing problem, warehousing, inventory management, and customer service are logistics problems. Graph theory algorithms provide solutions to problems such as the shortest path, minimum spanning tree, a company system with branches transfer centers which affiliated, if sorting process is carried out in centers, deliveries collected fro...

By adding a proper term to the Lagrangian density of a real non-linear KG system with a proposed non-topological unstable solitary wave solution, its stability guaranteed appreciably. This additional term in the new modified Lagrangian density behaves like a strong internal force which stands against any arbitrary small deformation in the proposed non-topological solitary wave solution.

this study is devoted to the formulation of the network design problem of one-way streets and the application of simulated annealing (sa) algorithm to solve this problem for a large real network. it discusses some points of views on one-way street networks, the objective function used for design, the way in which design constraints may be considered, and the traffic problems concerning one-way ...
