This paper presents an experimental study of the effects of tar on the performance of SOFCs with Ni/GDC anodes. Various operating temperature levels (700, 800 and 900°C) under both dry and wet conditions were employed in this study. Polarization behavior, electrochemical impedance spectroscopy,...

Batch processing machine scheduling in uncertain environment attracts more and more attention in the last decade. This paper deals with semi-online scheduling on two parallel batch processing machines with non-decreasing processing time of job. Jobs arrive over time in the online paradigm, and...

Momentum profits are shown to be driven by the broad-market persistence of returns between the formation period and the holding period, which is measured as the slope coefficient of the regression of the cross-section returns in the holding period on the cross-section returns in the formation...
