Sampling Continuous-time Sparse Signals: A Frequency-domain Perspective

We address the problem of sampling and reconstruction of sparse signals with finite rate of innovation. We derive general conditions under which perfect reconstruction is possible for sampling kernels satisfying Strang-Fix conditions. Previous results on t ...

Hybrid organizations influence on market competitive dynamics: the Azorean case

Joana Rodrigues Pereira

Hybrid organizations are an increasing phenomenon in pluralistic environments of modern societies. As this phenomenon grows, it has become more and more common that hybrids and non-hybrids compete and interact in the same market. This paper aims at investi ...

The DEMO wall load challenge

Ambrogio Fasoli, Jonathan Graves, Jan Horacek, David Pfefferlé, Samuel Lanthaler, Bernhard Sieglin, Hartmut Zohm

For several reasons the challenge to keep the loads to the first wall within engineering limits is substantially higher in DEMO compared to ITER. Therefore the pre-conceptual design development for DEMO that is currently ongoing in Europe needs to be based ...

Non-linear dynamics of compound sawteeth in tokamaks

Compound sawteeth is studied with the XTOR-2F code. Non-linear full 3D magnetohydrodynamic simulations show that the plasma hot core is radially displaced and rotates during the partial crash, but is not fully expelled out of the q = 1 surface. Partial cra ...

Producer cooperatives influence on competitive dynamics: the Azorean case

Joana Rodrigues Pereira

The aim of this paper is twofold: first, I aim at understanding how producer cooperatives compete in the factor markets; and second, I analyse how producer cooperatives influence the competitive dynamics of the markets where they compete. With this paper w ...

Competition of two Sulfurospirillum populations for tetrachloroethene

Géraldine Florence Buttet

Tetrachloroethene (PCE) represents a major groundwater pollutant. Some bacteria are able to use PCE as electron acceptor in an anaerobic respiration process called organohalide respiration (OHR). An anaerobic enrichment culture (named SL2-PCEb) consisting ...
