Nonlinear-Impairments- and Crosstalk-Aware Resource Allocation Schemes for Multicore-Fiber-based Flexgrid Networks

Dharmaweera, M.N.; Yan, L.; Zhao, J.; Wymeersch, H.; Agrell, E. (2016)

Abstract: In this study, we propose a novel spectrum and core allocation scheme that incorporates both intra-core physical layer impairments and inter-core crosstalk. We demonstrate that accounting for the latter increases ...
An impairment-aware resource allocation scheme for dynamic elastic optical networks

Dharmaweera, M.N.; Yan, L.; Zhao, J.; Wymeersch, H.; Agrell, E. (2017)

By using impairment-driven variable guardbands, our proposed dynamic resource allocation scheme accommodates 50% more traffic in comparison to existing fixed transmission-reach- and guardband-based algorithms.
Joint Assignment of Power, Routing, and Spectrum in Static Flexible-Grid Networks

Dharmaweera, M. N.; Yen, L.; Zhao, J.; Wymeersch, H.; Agrell, E. (2016)

This paper proposes a novel network planning strategy to jointly allocate physical layer resources together with the routing and spectrum assignment in transparent nonlinear flexible-grid optical networks with static traffic ...
Regenerator site selection in impairment-aware elastic optical networks

Dharmaweera, M. N.; Yan, L.; Zhao, J.; Karlsson, M.; Agrell, E. (2016)

We propose a novel regenerator site selection scheme for nonlinear impairment-aware elastic optical networks. The proposed scheme reduces bandwidth use by up to 40% in a realistic network by employing only 6 regenerator sites.
Centromere detection of human metaphase chromosome images using a candidate based method

Subasinghe, A.; Samarabandu, J.; Li, Y.; Wilkins, R.; Flegal, F.; Knoll, J. H. M.; Rogan, P.K. (2016)

Accurate detection of the human metaphase chromosome centromere is an critical element of cytogenetic diagnostic techniques, including chromosome enumeration, karyotyping and radiation biodosimetry. Existing image processing ...
Data assimilation in an ice-ocean coupled model to improve sea ice predictions in the Arctic Ocean

Mudunkotuwa, D.Y.; Yamaguchi, H. (2016)

We have improved the accuracy of sea ice predictions in the Arctic Ocean by assimilating sea ice variables in an ice-ocean coupled model. The model domain is 25km in resolutions. The results of the model only predictions ...
Data assimilation system to improve sea ice predictions in the Arctic Ocean using an ice-ocean coupled model

Mudunkotuwa, D.Y.; De Silva, L.W.A.; Yamaguchi, H. (2016)

With the recent changes in the Arctic climate, transportation in the Arctic Ocean has increased. It is important to accurately predict the ice conditions to navigate safely in the Arctic Ocean. In this study we have ...
Improving numerical sea ice predictions in the Arctic Ocean by data assimilation using satellite observations

Mudunkotuwa, D.Y.; De Silva, L.W.A.; Yamaguchi, H. (2016)

This study focuses on improving sea ice predictions in the Arctic Ocean by introducing data assimilation into an ice-ocean coupled Ice-POM model that is used to predict sea ice conditions in the Arctic sea routes. Ocean ...
