This paper presents some forecasting techniques for energy demand and price prediction, one day ahead. These techniques combine wavelet transform (WT) with fixed and adaptive machine learning/time series models (multi-layer perceptron (MLP), radial basis functions, linear regression, or GARCH)....

In recent years, computer has become powerful tool for prediction of economical and financial variables. Different techniques of topics related to artificial intelligence, machine learning, and expert systems extended their place in the economic and financial issues that among these issues can...

The new paradigms and latest developments in the Electrical Grid are based on the introduction of distributed intelligence at several stages of its physical layer, giving birth to concepts such as <i>Smart Grids</i>, <i>Virtual Power Plants</i>, <i>microgrids</i>, <i>Smart Buildings</i> and <i>Smart Environments</i>. <i>Distributed...</i>

A study was made on samples from one core collected immediately after the December 2004 Asian tsunami to know the geochemical nature of the offshore tsunami sediments. The core sample was analyzed for sediment grain size, CaCO<Subscript>3</Subscript>, organic carbon (OC) and major elements (SiO<Subscript>2</Subscript>, TiO<Subscript>2</Subscript>, Al<Subscript>2</Subscript>O<Subscript>3</Subscript>, Fe<Subscript>2</Subscript>O<Subscript>3</Subscript>,...</subscript></subscript></subscript></subscript></subscript></subscript></subscript>

This paper has two main aims: (i) to criticize the diagnosis about the research performance of the EU contained in the so-called “European Paradox”, according to which Europe plays a leading world role in terms of scientific excellence, but lacks the entrepreneurial capacity of the U.S. to...
