Hydrogen and Carbon Production via Methane Thermal Decomposition: Effects of Temperature and Residence Time [PDF]
Methane thermal decomposition is a promising technology for producing CO2-free hydrogen. This study experimentally examines how temperature (1,000–1,400oC) and residence time affect methane decomposition in a ceramic tubular reactor.

Lumped time-delay compensation scheme for coding synchronization in the nonlinear spectral quantization-based all-optical analog-to-digital conversion [PDF]
In this paper, we propose a novel lumped time-delay compensation scheme for the all-optical analog-to-digital conversion based on soliton self-frequency shift and optical interconnection techniques.

Understanding How People Rate Their Conversations
User ratings play a significant role in spoken dialogue systems. Typically, such ratings tend to be averaged across all users and then utilized as feedback to improve the system or personalize its behavior. While this method can be useful to understand broad, general issues with the system and its behavior, it does not take into account differences ...
