Investigation of purge time in cathodic dead-end mode PEMFC
Recently, special type of fuel cells has been developed that operates in a Dead End mode. Working in this condition, the Dead-End fuel cell is supplied withhydrogen almost at the same rate of consumption. It is noteworthy to mention thatall of the water transport mechanisms have been considered in this simulation.Water accumulation that is directly proportional to the cell current is of a grea...
متن کاملAppropriate energy window width for gamma camera [Persian]
Introduction: Scatter radiation is one of the major sources of error in nuclear medicine data processing. Different methods of scatter correction have been introduced in order to improve the quality of data. However the best method is to avoid recording of scatter photons in acquisition. The only difference between scattered and non-scattered photons is the energy. Pulse height analyzer i...

متن کاملA low energy dual-mode adder
VLSI designs are typically data-independent and as such, they must produce the correct result even for the worst-case inputs. Adders in particular assume that addition must be completed within prescribed number of clock cycles, independently of the operands. While the longest carry propagation of an n-bit adder is n bits, its expected length is only O(log2n) bits. We present a novel dual-mode a...
