the paper presents an analysis of both energy intensity and energy demand for the italianindustrial sector. the aim of the paper is twofold: making a decomposition of energy intensity at the aggregate level and modeling energy demand at the firm level. the decomposition of energy intensity shows different patterns for the different sub-sectors in the period of interest. in the micro approach, p...

when the past observations are correlated with future observations and their correlation is significant, the time series has long memory. in this paper the contagion effect of volatilities, with consideration of long-run effect, is investigated. the basic model is bekk (1, 1) and fbekk (1,d,1), model extended long-run memory parameter (d) is considered and estimated. furthermore in this paper p...

In water- and wastewater-treatment processes, knowledge of sludge settlement behavior is a key requirement for proper design continuous clarifier or thickener. One the most robust practical tests to acquire information about rate sedimentation through execution batch settling tests. lieu conducting series various initial concentrations, it promising advantageous develop simple predictive models...
