Using the MATLAB™ platform, groundwater quality in Jilin, China, is evaluated by employing integrated- and automation-type models. Genetic algorithm (GA), particle swarm optimisation, and support vector machine (SVM) theory are coupled in the model to form two-layer loop nesting. By using a GA, the surrounding loop enters the inner loop by choosing some factors from all measured evaluation factors...
In order to take the effective measure to jam the enemy's navigation system, GPS jamming shells, as the latest type of the jamming equipment, is widely used recently. In the process of the application of navigation interference, a number of GPS jamming shells are usually distributed to cover the target area without any vacancy, but it's a complex problem to distribute the shells to use the least quantities...
The Crane-umbrella Communication Jammer has become an important communication jamming equipment. During the interference process, the single jammer can cover a circular area and multiple jammers can be distributed to cover the target area without any vacancy, but it's a complex problem to distribute the jammers to use the least quantities of jammers, cover the maximal area and receive the signals...
The multi-source network coding problem, in which multiple multicast sessions with independent data share a network, is an open challenge. This paper proposes an approach to implement multi-source multicast sessions with linear network coding. We divide the original network into several sub-graphs, and each sub-graph contains a source node and its corresponding sink nodes. Links belonging to different...
