In our exciting world of pervasive computing and always-available mobile internet, meeting the educational needs of students has seen a growing trend toward collaborative electronic and mobile learning systems that build on the vision of Web 2.0. However, other trends relevant to modern students must not be ignored, including data freedom, brokerage and interconnectivity. Such factors are associated...
We propose a new compressive sensing scheme, based on codes of graphs, that allows for joint design of sensing matrices and low complexity reconstruction algorithms. The compressive sensing matrices can be shown to offer asymptotically optimal performance when used in combination with OMP methods. For more elaborate greedy reconstruction schemes, we propose a new family of list decoding and multiple-basis...
A new design to realise travelling-wave electro-optic modulators, which utilise a non-periodically polarisation-reversed structure to produce an arbitrary frequency response, is proposed. A flat and broadband electro-optic modulator compensated for both velocity mismatch and degradation by microwave loss is presented.
