This paper explores the current trajectory of multilateral governance for climate change adaptation in S. Korea, which is characterised by vertical and horizontal adaptation governance. This article highlights that the characteristics of adaptation governance can be realised more effectively through grassroot activities at both metropolitan and local(More)
This paper describes a time delay estimation (TDE) technique using compressive sensing (CS) off the grid, which estimates the channel impulse response in a continuous time domain. The TDE can be formulated into a sparse signal reconstruction problem where the CS technique can be applied. Previous works have used standard finite dimensional CS with evenly(More)

We present a time delay estimation method for sparse translation-invariant signals, off the grid. We enforce sparsity by imposing penalties based on an atomic norm to consider signals in a continuous domain. Our formulation leads to an atomic norm minimization problem. A number of recent theoretical results demonstrate that an atomic norm minimization can(More)
