Nonlinear analysis of a two-degree-of-freedom energy harvester

  • Frizzell R.

In recent years the use of Wireless Sensor Networks (WSNs) has increased rapidly, enabled by the development of small and ultra-low power electronics. The majority of these sensors are battery powered, and this can lead to high maintenance costs when batteries have to be replaced. A practical solution to power ...

TCP congestion control is the primary enabler for the coexistence of multiple application flows on a single link. It is designed to achieve long-term fairness between the multiplexed flows in a fully distributed manner. However, long-term fairness between TCP flows does not always translate into Quality-of-Experience (QoE) fairness between the ...

Detailed numerical investigation of self-seeded colorless ONU transmitter using quantum dot (QD) SOA as the intensity modulator for symmetric 40 Gb/s TWDM-PON has been developed. It is shown that the QD SOA-based intensity modulator is able to support 10 Gb/s OOK upstream signal transmission with an optical extinction ratio of ...

VLS4: Valiant Load Balanced Segment Routing

  • Hao F.
  • Kodialam M.
  • Lakshman T.

With the rapid rise in the number of diverse Internetbased applications, it is to be expected that network traffic patterns will vary widely. Significant traffic fluctuations from what is predicted may require corresponding routing adaptations to avoid congestion. Valiant Load Balancing (VLB), or equivalently two-phase routing, is a scheme that ...

The proof-of-concepts (PoC) in FANTASTIC-5G target is to implement key technical components developed within the project. The demonstration aims at validating the feasibility and the superiority of the different components of the foreseen 5G air interface. For this activity, several platforms are being developed in FANTASTIC-5G. The planned demonstrations are ...

A National Space Weather Service.

There are strong economic and "quality of life" reasons for developing a full-service, state-of-the-science National Space Weather Service. At present the nation's space weather services, as their operators acknowledge, fall short of providing forecasts with the reliability, accuracy, and specificity that customers desire. The technological, scientific, and infrastructural resources exist, ...

Birefringent multimode fibres have been found to preserve polarisation except for one mode near cutoff. Experimental observations and theoretical considerations show that polarisation ratios better than 20 dB are possible, offering the potential for building polarisation-sensitive multimode fibre components.

A technique for producing low-loss splices in single-mode fibres has been developed and evaluated. The splices are made by sandwiching the fibre butt-joint ends between a glass V-groove block and a flat glass plate, both of which are made by fibre-drawing techniques. A new splice-loss measuring technique is described. The ...
