Modeling Logical Interdependencies: Quantifying Systemic Risk From Rule‐Governed Actions

Risk Analysis, Volume 46, Issue 11, November 2026.
ABSTRACT Systemic risk in critical infrastructure is often analyzed through physical, geographic, and cyber interdependencies. Yet infrastructures are also interdependent through the governing rules that organize human action. These rule‐mediated connections are a form of logical interdependency, and breakdowns in rule‐governed action can create ...

Investigation on MIMO channels in subway tunnels

IEEE Journal on Selected Areas in Communications, 2003
The purpose of this paper is to examine the possibilities of increasing the channel capacity in tunnels, and particularly in railway tunnels, due to the use of multiple-input-multiple-output techniques. Many measurement campaigns have been carried out, considering the complicated geometric structure of these tunnels.

Two Methods for the Optimization of Subway Tunnel Profiles

2006 Canadian Conference on Electrical and Computer Engineering, 2006
This paper describes the energy minimization process of the longitudinal profile between two metro station platforms. Two algorithms are discussed: the genetic algorithms (GAs) with the profile coding process, and the Hook and Jeeves (H&J) direct search algorithm. GAs are a novelty for subway tunnel profile optimization.
