We examine a general model for the Fisher-KPP (FKPP) equation with nonlocal advection. The main interpretation of this is as describing diffusing and logistically growing population that also influenced by intraspecific attraction or repulsion. For particular choice parameters, specializes to Keller-Segel-Fisher chemotaxis. Our interest in effect chemotaxis on speed traveling waves. prove there...

The key motions of land and water are analyzed for a designed amphibious carrier robot. On land, based on the characteristics multi-joint crawler, robot has planned two gaits climbing steps land. kinematic models established gaits, maximum height that can climb is obtained based, Based laws dynamics, stability equation under strong transient impact to obtain conditions maintain its own when dur...

Using ant colony algorithm to solve TSP (traveling salesman problem) has some disadvantages as easily plunging into local minimum, slow convergence speed and so on. In order to find the optimal path accurately and rapidly, an improved ant colony algorithm is proposed. Experimental results show that the improved ant colony algorithm has better effectiveness for TSP problems solutions.
