Railways: Halted Multilateral Cooperation, Valid Multilateral Agreements

open access: yes, 2022
On the eve of the war, international rail exchanges were governed by numerous conventions and international organisations established during their first century of existence. How did this framework evolve and function during the war? Were other mechanisms planned or implemented to complement or replace it in Europe, possibly bridging post-war ...

An Effective PSO-Based Node Localization Scheme for Wireless Sensor Networks [PDF]

open access: yes
[[abstract]]Wireless sensor networks (WSNs) usually employ different ranging techniques to measure the distance between an unknown node and its neighboring anchor nodes, and based on the measured distance to estimate the position of the unknown node ...

Distributed on-line multidimensional scaling for self-localization in wireless sensor networks

open access: yes, 2015
The present work considers the localization problem in wireless sensor networks formed by fixed nodes. Each node seeks to estimate its own position based on noisy measurements of the relative distance to other nodes.
