The intensive and fast development of livestock farming with ecological pattern of raising-biogas-irrigating is widely applied in China. After anaerobic fermentation the agricultural wastes can provides clean energy. However, there is problem by lacking of land to digest the biogas slurry. Based on livestock wastewater from a dairy farming, the experiment used modified two-stage anoxic/oxic (A/O)...
In this paper, we propose an effective channel estimator by exploiting compressive sensing (CS) for multicarrier systems. Conventional linear channel estimators are considered optimal under the assumption of rich multipath, while the practical physical multipath channels tend to exhibit sparse structure. Exploiting the inherent sparsity, CS-based channel estimation can achieve higher spectral efficiency...
Emotional states are part of the information that is conveyed in many forms of network reviews. This paper presents a new sentiment polarity recognition model based on linguistic structure of emotion states-fixed sentiment terms model. The proposed method uses three types of specific collocation pattern to construct the recognition algorithm based on fixed sentiment terms. These feature term sets...
The local binary patterns statistical characteristics of the continuous wavelet transform scalogram of the aeroengine vibration signal are explored in this paper. The method is based on recognizing that certain uniform local binary patterns which are fundamental properties of local image texture and their occurrence histogram is proven to be a very powerful texture feature. Three patterns are studied...
According to the requirements of the State Grid Corporation's document and the local actual situation, this paper establishes the customer satisfaction evaluation indicator system. And it has carried on investigation in an area, and carried on the analysis of the investigation result. It proposes an appropriate customer satisfaction index structural equation model, and uses Amos software obtaining...
