A WDM-based PCN architecture

GLOBECOM 97. IEEE Global Telecommunications Conference. Conference Record, 2002
A WDM-based PCN architecture is proposed. Based on the broadcast nature of WDM star couplers, this WDM-based architecture gains several advantages over the current prominent ATM-based PCN architecture: (1) a fast hand-off scheme for roaming terminals, (2) an easy multicast routing implementation for mobile environment, and (3) a less number of ...

Phosphanyl Cyanophosphide Salts: Versatile PCN Building Blocks

Angewandte Chemie International Edition, 2019
AbstractThe facile preparation of alkali salts of phosphanyl cyanophosphides [NHP‐PCN]− (NHP=N‐heterocyclic phosphenium) is reported. Their formation is achieved by isoelectronic replacement of O for [N]− in the phosphaketenes NHP‐PCO using alkaline hexamethyldisilazide M[N(SiMe3)2] (M=Na, K) as reagent.

Leaping from the barricades (PCN)

IEEE Communications Magazine, 1992
Following extensive discussion between the US Federal Communications Commission (FCC) and private industry on competing personal communication system (PCS) technologies and regulatory policies, the FCC took a concrete step to address, in a notice of proposed rulemaking released in February 1992, the most critical issue to PCS development: spectrum ...

PCN: the probabilistic convergent network

Proceedings of ICNN'95 - International Conference on Neural Networks, 2002
A new architecture for networks constructed from RAM-based neurons is presented which, whilst retaining learning and generalisation properties possessed by existing RAM-based network architectures, allows for a regular treatment of specialisation and generalisation with the additional property of providing information regarding the relative probability

Proceso de Comunidades Negras (PCN)

2008
The thesis is written from a post-developmental perspective and attempts to determine if Proceso de Comunidades Negras (PCN) can be considered an embodiment of post-developmental ideas, as many scholars who study and analyzed this social movement attest. The thesis has two theoretical poles.
