7. Layered optical networks : implications to switching and transmission
Abstract : With the aim of supporting and enhancing high-capacitycommunication networks, such as telephony, Internet and others,this work has investigated:· transmission gains withtime-slotted optical communication, · performance ofoptical add/drop multiplexers (OADMs) and optical crossconnects(OXCs), · OXC networks serving Internet Protocol(IP)-routers, · packet hop reductions in IP-controlledoptical networks, · a simple optical neighbour discoverymethod, · economics of complementing a client network withan optical express layer.Time-slotting was shown to enable bi-directionaltransmission at the same frequency and multiwavelengthtransmission over dispersion-shifted fibre.

8. Energy Saving vs. Performance: Trade-offs in Optical Networks
Abstract : The energy consumption of communication networks is continuously growing. Many energy saving approaches have been proposed at the device, system, and network level. The most promising way to address this problem is to utilize photonic technologies as much as possible thanks to their low energy consumption per bit performance. READ MORE

9. Investigations of Issues Relevant to the Application of Photon Echoes in Information Technology
Abstract : Photon echoes have been studied both experimentally and theoretically, with the main part of the work centred around the concept of using photon echoes for all-optical data storage and processing. The four basic Boolean operators, AND, OR, NOT and XOR have been experimentally demonstrated using photon echoes. READ MORE

10. Distributions Of Fiber Characteristics As A Tool To Evaluate Mechanical Pulps
Abstract : Mechanical pulps are used in paper products such as magazine or news grade printing papers or paperboard. Mechanical pulping gives a high yield; nearly everything in the tree except the bark is used in the paper. This means that mechanical pulping consumes much less wood than chemical pulping, especially to produce a unit area of printing surface. READ MORE
