Sparse signal and image recovery from Compressive Samples [PDF]
, 2007 In this paper we present an introduction to Compressive Sampling (CS), an emerging model-based framework for data acquisition and signal recovery based on the premise that a signal having a sparse representation in one basis can be reconstructed from

Generalized small-signal modelling of dual active bridge DC/DC converter [PDF]
, 2018 this paper presents a novel generalised approach of the small-signal modelling of dual active bridge (DAB) DC/DC converter. The adopted analysis is based on a per-unit fundamental frequency representation of the DAB. The outcome of the proposed modelling

Discrete Optimization Methods for Group Model Selection in Compressed Sensing
, 2020 In this article we study the problem of signal recovery for group models. More precisely for a given set of groups, each containing a small subset of indices, and for given linear sketches of the true signal vector which is known to be group-sparse in ...

Active Damping of VSC-MTDC Grid Equipped With Interline Power Flow Controller
IEEE Access, 2022 To ensure the secure operation of a multiterminal high-voltage DC (MTDC) grid, power flow controllers (PFCs) are deployed to regulate current distribution among different transmission lines. Besides power flow management, PFCs are envisioned to provide a
