We constrain the deceleration-acceleration epoch, namely the transition redshift ztr, adopting model-independent techniques that utilize a calibrated Ep-Eiso correlation for gamma-ray bursts (GRBs). To do so, in addition to real data points, we employ up to 1000 simulated observational Hubble data (OHD) points. We then calibrate the Ep-Eiso correlation by means of the well-consolidate BCrossed D sign.
