To the Editor: A recent important study1 addressing the prevalence of cardiovascular risk factors in a rural African population, reports that ‘... most participants followed a physically inactive lifestyle’. The validity of their findings is difficult to evaluate as the study provides little information regarding the physical activity questionnaire that was used. Questionnaire validity is relev...

This paper discusses a case study of the board game of Scotland Yard from a computational perspective. Interestingly, Scotland Yard is a genuine “playgame” with imperfect information. For reasons not completely clear to me, games with imperfect information have escaped the interest of researchers in Algorithmic combinatorial gametheory. I show by means of a powerset argument, that Scotland Yard...

In this paper, a method integrating Q-learning algorithm and simulation technique is proposed to optimize the operation scheduling in container terminals. Firstly Q-learning algorithms for yard cranes and yard trailers are designed to obtain the optimal scheduling strategy of yard cranes and yard trailers. Then Q-learning is combined with simulation to develop an integrating scheduling model in...

The interaction of the dye YD2 with a cluster of (anatase-phase) TiO2 (which is utilized in dye-sensitized solar cells, DSSCs) and electron injection by the dye into the cluster were studied by performing density functional theory (DFT) calculations at the B3LYP, PBE, and TPSS levels of theory, including dispersion effects. We studied and quantified the interaction of the metallomacrocycle with...

This paper describes an integrated approach for crane automation at the Kwangyang steel works, POSCO. Unmanned cranes are composed of several technologies,which include anti-sway control, precision position control, optimal trajectory computation, and coil shape recognition. Crane position while traveling and the traverse axis are controlled by PID position controllers. In order to prevent sway...

soil is well known to support the transient or ongoing existence of kerathophilic fungi and potential sources of infection for humans and animals. fifty soil samples were collected from various areas of forests and farmyards at golestan province in the north part of iran to determine the prevalence of keratinophilic fungi and dominant species. a total of 357 fungal colonies including 13 genera ...
