Half-wavelength AC transmission line has the characteristics of long distance and high voltage level, its fault are significantly different from conventional line. In order to reduce interference distributed capacitive current on half-wavelength calculation differential protection, this paper proposes a new protection scheme based Bergeron model. solve problem small located at midpoint when sho...

Background: Vaccination against COVID-19 is as a key solution to interrupt its spread. This study aimed to describe the vaccination coverage required to stop the spread of COVID-19 in Sri Lanka using a mathematical modeling strategy. Materials & Methods: This longitudinal study used age-stratified and unstratified Susceptible-Infectious-Recovered (SIR) models. Data on the population's age dist...

Differential linear network coding (DLNC) is a precoding scheme for information transmission over random linear networks. By using differential encoding and decoding, the conventional approach of lifting, required for inherent channel sounding, can be omitted and in turn higher transmission rates are supported. However, the scheme is sensitive to variations in the network topology. In this pape...

This paper aims to analyse the design techniques of differential transmission lines loaded with metamaterials. Specifically, complementary split-ring resonators (CSRRs) were etched on the ground plane of a microstrip transmission line in order to mitigate both differentialand common-mode propagation in differential signalling. Several prototypes were manufactured and characterised in printed ci...

The role of many-body interactions is experimentally and theoretically investigated near the saddle point absorption peak of graphene. The time and energy-resolved differential optical transmission measurements reveal the dominant role played by electron-acoustic phonon coupling in band structure renormalization. Using a Born approximation for electron-phonon coupling and experimental estimates...
