Taking the maximum of system’s total throughput as a objective, the method of determining the surge bunker’s rational size is put forward. Also, the problems of rational position of surge bunker are analysesed.展开更多

The formulations were developed using the central composite rotational design and having as dependent variables specific volume, hardness, crumb color and image analysis. Statistical analysis was performed using multiple regression and response surface. The results showed that the inclusion of powdered acai and polydextrose in bread formulations reduces the specific volume and alveoli number and increases the browning and hardness of the bread. However, values of this addition （30 g/100 g） were found that did not promote significant quality reduction and the scanning electron microscopy （SEM） showed minimal damage to the gluten network at this level of incorporation.展开更多

The proposed optical transceiver consumes 0.9 W power and retains a small size of 28 mmx16 mmx3 mm. The fabrication process of the silicon substrate and the assembly process of the optical transceiver are demonstrated in details. Moreover, the optical transceiver is measured in order to verify its transmission performance. The clear eye diagrams and the low bit error rate （BER） less than 1013 at 10 Gbit/s per channel show good transmission characteristics of the designed optical transceiver.展开更多
