An Envelope Method for Analyzing Sequential Pattern Formation
نویسندگان
چکیده
We examine sequential spatial pattern formation in a tissue interaction model for skin organ morphogenesis. Pattern formation occurs as a front sweeps across the domain leaving in its wake a steady state spatial pattern. Extensive numerical simulations show that these fronts travel with constant wave speed. By considering the envelope of the solution profile we present a novel method of calculating its wave speed.

Combined mining is a technique for analyzing object relations and pattern relations, and for extracting and constructing actionable complex knowledge (patterns or exceptions) in complex situations. Although combined patterns can be built within a single method, such as combined sequential patterns by aggregating relevant frequent sequences, this knowledge is composed of multiple constituent com...

متن کاملDevelopment of Hydrate Formation Phase Envelope: An Experimental Approach in One of the Iranian Gas Reservoirs
Iran's proved natural gas reserves are the world's second largest reserves. Mainly, because of different climate changes and different reservoirs characterizations, studying the behavior of producing outcome fluids and their transportation, is of major interest. One of the main problems occur in the gas reservoirs is related to the hydrate formation while producing from a well, either in produc...
