Numerical Weather Prediction (NWP) and hybrid ARMA/ANN model to predict global radiation
We propose in this paper an original technique to predict global radiation
using a hybrid ARMA/ANN model and data issued from a numerical weather
prediction model (ALADIN). We particularly look at the Multi-Layer Perceptron.
After optimizing our architecture with ALADIN and endogenous data previously
made stationary and using an innovative pre-input layer selection method, we
combined it to an ARMA model from a rule based on the analysis of hourly data
series. This model has been used to forecast the hourly global radiation for
five places in Mediterranean area. Our technique outperforms classical models
for all the places. The nRMSE for our hybrid model ANN/ARMA is 14.9% compared
to 26.2% for the na\"ive persistence predictor. Note that in the stand alone
ANN case the nRMSE is 18.4%. Finally, in order to discuss the reliability of
the forecaster outputs, a complementary study concerning the confidence
interval of each prediction is proposedComment: Energy (2012)
About the Impossibility of Absolute State Sovereignty. The Modern Era and the Early Legal Positivist Claim
State sovereignty is often thought to be and seen as absolute, unlimited. However, there is no such a thing as absolute state sovereignty. Indeed, absolute or unlimited sovereignty is impossible because all sovereignty is necessarily underpinned by its conditions of possibility. The present chapter consists of two main parts. Firstly, and in order to show more clearly how sovereignty is limited, two kinds of agents are introduced: (a) individuals; and (b) states. The aim is to demonstrate how different sorts of constraints or limitations operate in relation to individuals and states without diminishing their respective sovereignties. Secondly, the chapter identifies specific theorists that take sovereignty to be absolute in the modern era, focusing in particular on two bodies of literature that constitute the roots for current legal positivism—i.e. Jean Bodin and Thomas Hobbes—and argues that in both cases they introduce conceptual, substantial, and contextual limitations. I argue that the modern era starts with a relative essence of sovereignty that has its origin in the working logic of fragmented regulatory governance. With this early and disjointed background of a national and transnational plurality of sources both Bodin and Hobbes aim to bring together these heterogeneous elements under the contextualisation of the paradox of sovereignty. The implications of understanding state sovereignty as limited rather than absolute are several, both directly and indirectly. A main immediate consequence is that sovereign states can cooperate together, limit their sovereignty and still be considered sovereign
