In Road Transportation, truck transportation is commonly being categorized into Less Than Truckload (LTL), Partial and Full (TL). The standard LTL carried out by means of consolidated freight at optimized depots designation, in the form single or multiple assignment. Nowadays, industry now facing a serious problem scarce labor force environmental concerns. One solution for that platooning. Truc...

Planning the transition period for the adoption of alternative fuel-technology powertrains is a challenging task that requires sophisticated analysis tools. In this study, a system dynamic approach was applied to analyze the bi-directional interaction between the development of the refueling station network and vehicle sales. Besides, the developed model was used to estimate the transition cost...

A novel polyaniline/Bi(2)SnTiO(7 )composite polymer was synthesized by chemical oxidation in-situ polymerization method and sol-gel method for the first time. The structural properties of novel polyaniline/Bi(2)SnTiO(7) have been characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy and X-ray spectrometry. The lattice parameter of Bi(2)SnTiO(7) was f...

n engl j med 367;24 nejm.org december 13, 2012 2265 Mississippi . . . .” We’d been told that if the electricity came back on before we hit “ten-Mississippi,” then the backup generators were working fine. A communal sigh was heaved when the count stopped short of double digits. Ventilators and intravenous (IV) pumps hummed on without a hitch. Downstairs, however, water was pouring into the basem...

This paper provides background and suggestions for safety research for the Army’s 21st Century Truck program (21T). The goal of that program is to reduce large truck related fatalities by 50 percent by the year 2010. As background for the proposed research program, this paper contrasts military and civilian trucks and their drivers. Based on that information and considerations of new technology...

The main objective of this work was to investigate the potential hydrogen and fuel cells replacing diesel internal combustion engines in ultraclass haul trucks deployed mining sector. Performance, range, durability, cost are criteria considered for comparing two fuels engine options. Fuel cell system (FCS) performance is characterized terms heat rejection, efficiency, consumption a hybrid platf...

The increasing share of light trucks in the USA has been characterized as an ‘arms race’ where individual purchases of light trucks for better self-protection nevertheless worsen traffic safety for society. This paper investigates the interrelation between traffic safety and vehicle choice by quantifying the effects of the arms race on vehicle demand, producer performance, and traffic safety. T...

The purpose of this paper is to develop a methodology to evaluate the feasibility of using landfill gas (LFG) as a liquefied natural gas (LNG) fuel source for heavy-duty refuse trucks operating on landfills. Using LFG as a vehicle fuel can make the landfills more self-sustaining, reduce their dependence on fossil fuels, and reduce emissions and greenhouse gases. Acrion Technologies Inc. in asso...

Two-dimensional Bi₂Se₃ nanosheets with hexagonal shape are synthesized by a solution synthetic route. The Bi₂Se₃ nanosheets are 120 nm in edge width and 7 nm in thickness. The size of the Bi₂Se₃ nanosheets can be controlled by choosing different kinds of reducing agents including hydroxylamine and ethylenediamine. Subsequently, we demonstrate a configuration of two-color all-optical switching b...

One of the key issues in mining is the hauling system. Truck and shovels are the most widely used transportation equipment in mines. In this paper, a two-phase simulation-based optimization is presented to maximize utilization of hauling system in the largest Iranian open-pit copper mine. In the first phase, The OptQuest for Arena software package was used to solve the optimization problem to p...
