Sistema polÃtico y movimientos indÃgenas: el caso del EZLN
El presente artÃculo analiza la vinculación del EZLN con la situación miserable en que se encuentran millones de indÃgenas en México contra la ingobernabilidad neoliberal. Presentamos posibles soluciones al conflicto EZLN, y resumimos los logros alcanzados por los grupos étnicos en materia de democracia dentro del Estado mexicano
Testing Hybrid Natural Inflation with BICEP2
We analyse Hybrid Natural Inflation in view of the recent results for the
tensor index reported by BICEP2. We find that it predicts a large running of
the scalar spectrum which is potentially detectable by large scale structure
and observations. The running of the running is also
relatively large becoming close to . Along the way, we find general
consistency relations at which observables are subject if the slow-roll
approximation is imposed. Failure to satisfy these equations by the values
obtained for the observables in surveys would be a failure of the slow-roll
approximation itself.Comment: V3: Published versio
Dispa-SET 2.0: unit commitment and power dispatch model
Most analyses of the future European energy system conclude that in order to achieve energy and climate change policy goals it will be necessary to ramp up the use of renewable energy sources.
The stochastic nature of those energies, together with other sources of short- and long-term uncertainty, already have significant impacts in current energy systems operation and planning, and it is expected that future energy systems will be forced to become increasingly flexible in order to cope with these challenges. Therefore, policy makers need to consider issues such as the effects of intermittent energy sources on the reliability and adequacy of the energy system, the impacts of rules governing the curtailment or storage of energy, or how much backup dispatchable capacity may be required to guarantee that energy demand is safely met.
Many of these questions are typically addressed by detailed models of the electric power sector with a high level of technological and temporal resolution. This report describes one of such models developed by the JRC's Institute for Energy and Transport: Dispa-SET 2.0, a unit commitment and dispatch model of the European power system aimed at representing with a high level of detail the short-term operation of large-scale power systems. The new model is an updated version of Dispa-SET 1.0, in use at the JRC since 2009.JRC.F.6-Energy Technology Policy Outloo
Integrated modelling of future EU power and heat systems: The Dispa-SET v2.2 open-source model
This report describes the implementation of the Dispa-SET model version 2.2. It extensively describes the model equations, the model inputs, and the resolution process. This version of Dispa-SET focuses more specifically on the inclusion of the heating sector, with a new dedicated module. It allows simulating the potential interactions between heat and power and the exploitation of thermal storage as a flexible resource. The model is an open-source tool and comes with an open dataset for testing purposes. It can therefore be freely re-used or modified to fit the needs of a particular case study.JRC.C.7-Knowledge for the Energy Unio
