a novel low noise trans-impedance amplifier is proposed using low cost 0.18 µm cmos technology. a resistive-capacitive feedback is used to extend the bandwidth of the amplifier. as the structure is inductor less, it is suitable for low cost integrated optical interconnects. in this paper improved particle swarm optimization have applied to determine optimal trans-resistance and noise of propose...

transaction cost economics (williamson, 1985) is a theory of the firm in new institutional economics that has been applied for analysing economic transaction; especially, make-or-buy decisions or vertical mergers in firms. the contribution of this paper is applying this theory for a political issue that is party formation. transaction cost economics links the party formation to the transaction ...

Algae-based fuel are considered a promising sources of clean energy, and because it has many advantages over traditional biofuel, research and business ventures have driven into developing and producing Algal-biofuel. But its production stages create a cost structure that it is not competitive with traditional fuels. Therefore, cost becomes the main obstacle in commercial production purpose. Ho...
