Significant public procurement changes are forcing road construction companies to professionalise planning and control of asphalt paving projects. In an effort to outperform competitors, companies seek better control over the paving process, over the planning and scheduling of resources and work, and over performance. For the asphalt paving companies to be able to improve product and process pe...

In English, many words can be used flexibly to label artifacts, as nouns, or functional uses of those artifacts, as verbs: We can shovel snow with a shovel and comb our hair with a comb. Here, we examine whether young children form generalizations about flexibility from early in life and use such generalizations to predict new word meanings. When children learn a new word for an artifact, do th...

Truck arrival management (TAM) has been recognized as an effective solution to alleviate the gate congestion at container terminals. To further utilize TAM in improving the overall terminal performance, this study integrates TAM with the other terminal operations at a tactical level. An integrated planning model and a sequential planning model are presented to coordinate the major terminal plan...

This work presents three multi-objective heuristic algorithms based on Two-phase Pareto Local Search with VNS (2PPLS-VNS), Multi-objective Variable Neighborhood Search (MOVNS) and Non-dominated Sorting Genetic Algorithm II (NSGA-II). The algorithms were applied to the open-pit-mining operational planning problem with dynamic truck allocation (OPMOP). Approximations to Pareto sets generated by t...

For the peanut combine harvester excavation process resistance, poor soil crushing effect and reliability of problem, shovel optimization needs improvement. Firstly, a mechanical model resistance was established to investigate key factors affecting degree shovel. Next, design main parameters done determine range values EDEM software used simulate analyse explore influence law on resistance. Imp...

The Truck Factor designates the minimal number of developers that have to be hit by a truck (or quit) before a project is incapacitated. It can be seen as a measurement of the concentration of information in individual team members. We calculate the Truck Factor for 133 popular GitHub applications, in six languages. Results show that most systems have a small truck factor (46% have Truck Factor...

OBJECTIVE This study presents data from a large-scale anthropometric study of U.S. truck drivers and the multivariate anthropometric models developed for the design of next-generation truck cabs. BACKGROUND Up-to-date anthropometric information of the U.S. truck driver population is needed for the design of safe and ergonomically efficient truck cabs. METHOD We collected 35 anthropometric d...

Mining of copper and gold at Kansanshi is done in the Main North West pits using hydraulic excavators a mining fleet haul trucks. In recent past, there has been reduced truck deployment, increased shovel waiting time, production grade/quality ore delivered to crushers. Therefore, need improve productivity optimise operations mining, loading hauling. This paper focuses on use High Precision (HPM...

To examine the relationship of ramp design to truck accident rates, this paper presents an analysis of truck accidents in Washington State, plus a comparison to limited data from Colorado and California. We group freeway truck accidents by ramp type, accident type, and by four conflict areas of each merge or diverge ramp. We then compare these groups on the basis of truck accidents per location...
