Currently there are a dozen or so of new vaccine candidates in clinical trials for prevention of tuberculosis (TB) and each formulation attempts to elicit protection by enhancement of cell-mediated immunity (CMI). In contrast, most approved vaccines against other bacterial pathogens are believed to mediate protection by eliciting antibody responses.(More)
A supercritical fluid extraction (SFE) method with an online solid collection trap has been developed for the quantitative analysis of 16 polycyclic aromatic hydrocarbons (PAHs) and 15 typical PAH derivatives in solid matrix. Compared with liquid trapping and C18 solid-phase trapping, multi-walled carbon nanotubes (CNTs) were proved to be the most efficient(More)
Since conventional cross–validation bandwidth selection methods don't work for the case where the data considered are dependent time series, alternative bandwidth selection methods are needed. In recent years, Bayesian based global bandwidth selection methods have been proposed. Our experience shows that the use of a global bandwidth is however less(More)
Bandwidth plays an important role in determining the performance of local linear es-timators. In this paper, we propose a Bayesian approach to bandwidth selection for local linear estimation of time–varying coefficient time series models, where the errors are assumed to follow the Gaussian kernel error density. A Markov chain Monte Carlo algorithm is(More)
Since conventional cross–validation bandwidth selection methods do not work for the case where the data considered are serially dependent, alternative bandwidth selection methods are needed. In recent years, Bayesian based global bandwidth selection methods have been proposed. Our experience shows that the use of a global bandwidth is however less suitable(More)
With regard to the over-segmentation of the traditional watershed transform, the paper proposes an algorithm using watershed transform based on optimized grid for color image segmentation. The algorithm transforms RGB color space to Lab color space and quantifys the color channels a and b in accordance with the grid-required. The watershed transform(More)
In reality, most economic entities are hierarchical organizations. But in the hierarchical organizations tacit knowledge can be transferred across different hierarchies even across different departments. By use of complex networks technology, a hierarchical organization's framework is modeled in this paper. Through quantifying a number of technical datas we(More)
To conduct real-time and accurate positioning of the forklifts (people) and goods in the warehouse is an effective means for improving warehouse management efficiency. To this end, this article puts forward the active positioning system with the forklift installed with RFID reader and the ground passageway embedded with RFID tag. In the running process, the(More)
This paper investigates the optimal model predictive control for the path tracking of an autonomous vehicle. For the control algorithm of an autonomous vehicle following pre-calculated path, two indices must be considered: 1. The performance index including the path tracking error and the energy consumed in control process. 2. The computational cost. In(More)
