DD Optical Systems over Dispersion-Uncompensated Links [PDF]
, 2022 We experimentally demonstrate a C band 100Gbit/s intensity modulation and direct detection entropy-loaded multi-rate Nyquist-subcarrier modulation signal over 100km dispersion-uncompensated link. A record capacity-reach of 10Tbit/s×km is achieved.

Can Generalized Poisson model replace any other count data models? An evaluation
Clinical Epidemiology and Global Health, 2021 Background: Count data represents the number of occurrences of an event within a fixed period of time. In count data modelling, overdispersion is inevitable.

Clustering over‐dispersed data with mixed feature types
Statistical Analysis and Data Mining: The ASA Data Science Journal, 2018 Despite many data clustering methods are available, most of them uncover compactness or connectivity as the intrinsic structure of unlabeled data. Very few approaches explicitly consider the cluster size distribution, especially over‐dispersed (high variance), which may represent yet another important aspect of structural information of unlabeled data.

Discrimination between Some Over Dispersed Count Distributions
ASM Science Journal, 2021 The Poisson inverse Gaussian and generalized Poisson distributions are widely used in modelling overdispersed count data which are commonly found in healthcare, insurance, engineering, econometric and ecology. The inverse trinomial distribution is a relatively new count distribution arising from a one-dimensional random walk model (Shimizu & ...

Study on Dispersion of Carbon Dioxide over the Shrubbery Region
Frontiers in Energy Research, 2021 In the carbon capture and storage (CCS) infrastructure, the risk of a high-pressure buried pipeline rupture possibly leads to catastrophic accidents due to the release of tremendous amounts of carbon dioxide (CO2).

Dispersion management in nonlinear photonic crystal fibres with nanostructured core [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 The subwavelength structure of the core of a photonic crystal fibre can modify its dispersion characteristic and significantly shift the zero dispersion wavelength.

CO2 dispersion modelling over Paris region within the CO2-MEGAPARIS project [PDF]
Atmospheric Chemistry and Physics, 2013 Accurate simulation of the spatial and temporal variability of tracer mixing ratios over urban areas is a challenging and interesting task needed to be performed in order to utilise CO2 measurements in an atmospheric inverse framework and to better ...
