Abstract This paper addresses the multi-objective optimization for road–rail intermodal routing problem that aims to minimize total costs and carbon dioxide emissions of routes. To achieve high timeliness entire transportation process, pickup delivery services are simultaneously improved based on employment fuzzy soft time windows measure their service levels. The modeling considers fixed sched...
The purpose of this study was to determine the range of optimum intermodal delay values for coordinated auditory and haptic reproduction of brief impact events. Indirect psychophysical methods were used to find the intermodal delay that would be most likely to generate the response of perceived synchrony between acoustic and structural vibration components of those events. A recording of a repr...
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...
We present a comprehensive study of an in-line Mach-Zehnder intermodal interferometer fabricated in a boron-doped two-mode highly birefringent microstructured fiber. We observed different interference signals at the output of the interferometer, related to the intermodal interference of the fundamental and the first order modes of the orthogonal polarizations and a beating of the polarimetric s...
Speaking faces, baking bread, speeding cars—the world provides a richly structured, continuously changing stream of stimulation to all of our senses. Intermodal perception (also called intersensory or multimodal perception) refers to perception of information from objects or events available to multiple senses simultaneously. Because most objects and events can be seen, heard, and touched, ever...
Numerous studies have demonstrated effects of spatial attention within single sensory modalities (within-modal spatial attention) and the effect of directing attention to one sense compared with the other senses (intermodal attention) on cortical neuronal activity. Furthermore, recent studies have been revealing that the effects of spatial attention directed to a certain location in a certain s...
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...
Grain supply chain transportation problem is a nontrivial and intractable issue for many developing countries. as bulk commodity usually transported by carriers. By taking into account the special condition of Ukraine, we proposed containerized grain optimization problem. In this problem, sustainable system delivers grains in containers among primary elevators, intermodal yards, port container ...
Degenerate four-wave mixing is considered in large mode area hybrid photonic crystal fibers, combining photonic bandgap guidance and index guidance. Co- and orthogonally polarized pump, signal and idler fields are considered numerically by calculating the parametric gain and experimentally by spontaneous degenerate four-wave mixing. Intermodal and birefringence assisted intramodal phase matchin...
The exponential growth of the flow of goods and passengers, fragility of certain products and the need for the optimization of transport costs impose on carriers to use more and more multimodal transport. In addition, the need for intermodal transport policy has been strongly driven by environmental concerns and to benefit from the combination of different modes of transport to cope with the in...
