—Energy efficiency (EE) maximization in MIMO systems has received much attention in next generation wireless communications. Within recent years, a lot of great works have been proposed to improve EE dramatically by power allocation and/or antenna selection. However, the systems significantly exploiting multiuser diversity were not considered in these(More)
The exact inner 3D microstructure of the human peripheral nerve has been a mystery for decades. Therefore, it has been difficult to solve several problems regarding peripheral nerve injury and repair. We used high-resolution X-ray computed microtomography (microCT) to scan a freeze-dried human acellular nerve allograft (hANA). The microCT images were then(More)
Application of latent Dirichlet allocation (LDA) in text analysis has received much attention because it is capable of characterizing the hidden topics of the documents within the Bayesian framework. In this paper, we train the LDA model with financial research reports to predict the most correlated industries of the financial news among the 24 first-level(More)
Energy efficiency (EE) maximization for OFDM transceiver has received much attention in next generation wireless communication systems. Recently, there have been a lot of works on EE maximization by balancing the transmission rate and the holistic power consumption. However, how to maximize EE in OFDM systems by joint power allocation and subcarrier(More)
Capturing CO2 from the flue gas of a power plant based on chemical absorption method is an effective way to cut down the emission of CO2. However, the principal components in the solvent are very difficult to be measured online. Therefore an online measurement and control system was designed for the process of capturing CO2 by MEA chemical absorption. The(More)
