An important barrier towards the introduction of fuel cell vehicles (FCVs) running on hydrogen is the lack of widespread refueling infrastructure. The niche of buses for public transport, taxis and deliverers with a local application area might not be large enough to generate the reductions of FCV costs that are necessary for a general technology switch. Thus, fuel availability at trunk roads p...

Due to global concerns about environmental sustainability in ground logistics, there has been widespread research into alternative-fuel (alt-fuel) vehicles. Compressed natural gas buses have been successfully deployed on a commercial scale in public transportation. Also, sales for electric cars have been gradually increasing. However, uses of other alt-fuel vehicles are in their early stages be...

Historically, gasoline and diesel fuels have been used for transportation, but the possible decline of oil supplies in the future is forcing nations to consider alternative fuels. Most technically and economically feasible alternative fuels have a lower energy density than gasoline, which results in a shorter range for these vehicles. This necessitates a greater need for convenient access to re...

During their fall migration from the Arctic to South America, semipalmated sandpipers Calidris pusilla stop in the Bay of Fundy (east coast of Canada) before flying non-stop for approximately 4500 km across the ocean. Refueling birds double their body mass by feeding on Corophium volutator, an amphipod containing high amounts of n-3 polyunsaturated fatty acids (n-3 PUFA), particularly eicosapen...

The purpose of this paper is to provide an expected cost comparison for operating a transit-bus fleet on three different alternative fuels-biodiesel, compressed natural gas (CNG), and methanol. Petroleum diesel is the base fuel. Infrastructure, refueling, and maintenance costs are all part of running an urban transit bus. Additional expenditures would be needed to change fuel storage and delive...

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...

This study addresses the continuous deviation-flow refueling station location problem on a general network. Instead of having finite number candidate locations, we consider any point in network as location. In addition, vehicles are allowed to deviate from their prescribed (shortest) paths refuel. At beginning, focus single facility, which is relevant initial stages development infrastructure f...

The paper proposes a technology for automated video-based observation (VBO) of drogue-sensor in the problem aerial refueling. is based on use passive optoelectronic system and incorporates logic refueling process using algorithms automatic detection tracking drogue-sensor, methodical apparatus suboptimal linear filtering observed under conditions spatial temporary non-stationarity process, corr...

Most real world planning and scheduling domains are only partially amenable to optimized solutions due to size of the solution space and due to the impossibility of fully optimizing a problem that changes over time. In addition, even an “optimal” solution to a problem is of little use if it is not comprehensible to end users of the system. In this paper we describe the AMC Barrel Allocator, a r...
