Microstructured titanium (Ti) surfaces often suffer from poor hydrophilicity which makes the realization of open microfluidic devices difficult. Here, we investigate the effect of a superficial porous titania (TiO2) layer on the hydrophilicity of microstructured surfaces. High aspect ratio Ti micropillars were micromachined from bulk Ti sheets. Porous TiO2(More)
At present RFID indoor positioning data visualization methods are simple and the visual effect is not ideal. To solve this problem, a method is put forward, which can make RFID indoor localization algorithms implement in a geographic information system. By overlaying the CAD floor plan with the outdoor maps, every indoor space positioning result has a(More)
In this paper, the intelligent optimization methods including particle swarm optimization (PSO) and modified particle swarm optimization (MPSO) are used in optimizing the project scheduling of the first mining face of the second region of the fifth Ping'an coal mine in China. The result of optimization provides essential information of management and(More)
Conditional Akaike information criterion is derived within the framework of conditional-likelihood-based method for binary response generalized linear mixed models. The criterion essentially is the asymptotically unbiased estimator of conditional Akaike information based on maximum likelihood estimator. The proposed criterion is adopted to address the model(More)
