This research is motivated by the extraordinary increase in the use of intermodal shipments in recent years for both domestic and global movement of freight. Three mathematical models, which explore the dynamics of intermodal hub-and-spoke networks, are presented. These models use transportation costs, fixed location costs, modal connectivity costs, modal transit times and service time requirem...

Background Telestroke network can provide rapid access to specialized treatment and improves on‐site management of acute stroke patients through the “hub‐and‐spoke” model. In northern part Okayama Prefecture, there has been a regional gap care due shortage specialists facilities. addition, novel coronavirus disease 2019 (COVID‐19), it is required reduce unnecessary contact with from other hosp...

The CSR Development and Evaluation Spokes data collection task yielded 4435 development test utterances fr~n 30 speakers and 4878 evaluation test utterances from a different set of 30 speakers. The development test data covered eight different spoke conditions, each of which had its own distinct combination of subject, prompt text, microphone and recording environment requirements. Similarly, t...

A sustainable alternative to fossil fuels is biomass. The design of cost-efficient biomass networks necessary compete with nonrenewable resources. creation integrated supply chain (BSC) network models and solution procedures can contribute the achievement this goal. In particular, emerging bioenergy industry must take advantage economies scale in transportation minimize final product’s cost. Hu...

This document describes the framework of the Softwire "Hub and Spoke" solution with the Layer Two Tunneling Protocol version 2 (L2TPv2). The implementation details specified in this document should be followed to achieve interoperability among different vendor implementations. Table of

hub location problems are among the extensions ofclassical location problems that have numerous applications in designingtransportation, postal, and telecommunication networks. despite the evidentattention of researchers to these problems, there are few studies on designinghub networks under uncertainty and disruption. in this study, the capacitatedsingle allocation hub location problem under d...
