Almost all the natural or human made systems can be understood and controlled using complex networks. This is a difficult problem due to the very large number of elements in such networks, on the order of billions and higher, which makes it impossibl...

When dealing with networks, performance management through conventional quality of service (QoS)-based methods becomes difficult and is often ineffective. In fact, quality emerges as an end-to-end factor, for it is particularly sensitive to the end-u... Read More about Resilience of Video Streaming Services to Network Impairments.

Intermodal freight terminals: a life cycle governance framework. (2016)
Book
Monios, J., & Bergqvist, R. (2016). Intermodal freight terminals: a life cycle governance framework. Ashgate Publishing

Much work has been done on port governance yet little has addressed intermodal terminal governance, despite the clear similarities. This book fills that gap by establishing a governance framework for situating analysis of intermodal terminals through...
