Two approaches to experimentally observe the hysteresis relation are discussed in detail. Advanced data analysis methods are also illustrated. A theoretical analysis of the process that couples heat to turbulence is also addressed.}, title = {Approaches to Hysteresis of Transport Relations in Toroidal Plasmas}, volume = {11}, year = {2016} }
