Seaport terminals recognise the need to change current practices in order to improve regional air quality while enhancing their terminals’ competitiveness. One area that terminals can do better at is to improve their yard crane operations and in turn reduce the trucks in-terminal delay. This study examines various container rehandling strategies by the yard cranes with the goal of improving the...

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 present investigation was laid out in Completely Randomized design (CRD) with nine treatments and each replicated thrice. treatment T2 i.e., Soil + Sand Perlite Farm yard manure 1:1:1:1) reported significantly better Performance terms of Growth parameters like plant height (60.50 cm), Number leaves per (64.00), spread (27.80 leaf length (7.60 cm); Flowering days to first flower bud appearan...

A field experiment was carried out in Zaid 2022 at the Department of Agronomy's Agricultural Research Farm Prayagraj (Uttar Pradesh). There are three planting geometries used 30 cm x 10 cm, 40 and 50 cm. nitrogen management treatments 50% Recommended Dose Nitrogen (RDN) through inorganic fertilizer, RDN th rough fertilizer combination with provided yard manure Azotobacter seed inoculation, fert...

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...
