Automation methods for huge amount of computations in grid environment and their applications in Ukrainian National Grid (UNG) are described. Proposed methods are based on asynchronous job submission and control. Methods has solved the problems of job data staging in, description preparing, job submission, job status monitoring and staging out results.(More)

We demonstrate that chimera behavior can be observed in small networks consisting of three identical oscillators, with mutual all-to-all coupling. Three different types of chimeras, characterized by the coexistence of two coherent oscillators and one incoherent oscillator (i.e., rotating with another frequency) have been identified, where the oscillators(More)
