In this paper, we present a novel classification model which combines the convolutional sparse coding framework with the classification strategy. In the training phase, the proposed model trained a convolutional filter bank by all images of each class. In the test phase, the label of test image is determined by all convolutional filter banks. Compared with canonical sparse representation and dictionary...
In the coal-fired generating units, the primary air that used to dry and carry coal dust had a direct effect on the burning operation mode in boiler furnace. Too large or too small air-coal ratio would affect the formal combustion of coal dust in the boiler. A high primary air flow which could lead to a high wind pressure had an adverse effect on the primary air tube and burner wear. Moreover, when...
Cognitive radio has been recognized as one of the most promising technologies dealing with the scarcity of the radio spectrum. In cognitive radio system, with spectrum sensing, secondary users are allowed to utilize the frequency bands of primary users when the bands are idle. Hence, how to accurately detect the idle frequency bands has attracted many researchers' eyes. Energy detection is the common...
