In this work, we study the Kuramoto model on scale-free, random and small-world networks with bimodal intrinsic frequency distributions. We consider two models: in one of them, the coupling constant of the ith oscillator is independent of the number of oscillators with which the oscillator interacts, and in the other one the coupling constant is renormalized with the number of oscillators with ...

Offshore oil/gas pipelines are usually installed unburied. Free spans in the line may occur initially by an uneven seabed or be created later due to under-scouring. Free spans are usually unfavourable spots in the submarine pipeline. They are vulnerable to vortex induced vibrations, excessive stresses in the pipe wall or may exhibit undesirable responses to strong ground excitations. In this pa...

Today, preferential and free trade agreements play an effective role in expanding trade in goods and services at the international level and as common practice in business planning and facilitating trade. The purpose of this article is to examine the trade and welfare effects of Iranchr('39')s free trade agreement with Turkey, India and Pakistan. For this purpose, using the Computable General E...

run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
