The power that utilities generate (or buy) to service a region is based on a rough estimate made 24 hours earlier of how much power a particular geography will need based on average monthly energy use from the previous year.
Based on average weekly energy expenditure, participants were categorized as sedentary (<1000 kcal/week), moderately active, (1000 1999 kcal/week), and active (≥2000 kcal/week) [ 22].
Physical activity was assessed based on average daily energy expenditure in leisure time physical activities (kcal/kg/day) in the past 3 months, and were categorized as inactive (0 1.5), moderate (1.5 3), and active (≥3).
Finally, the concept of cooperative binding is analyzed in order to underline the limitations of the pure additive calculation method based on average binding energies.
Ecologic studies, while providing weaker evidence, also have been largely consistent in showing a negative correlation between breast cancer risk and potential UV exposure, based on average ground-level solar energy (Garland et al. 1990; Gorham et al. 1990), latitude (Grant 2010), or acid haze (Gorham et al. 1989).
Traditionally, the impact of intermittency has not been taken into account, but rather theories were based on average values of the rate of kinetic energy dissipation, velocity fluctuations, rates of strain, turbulent stresses, etc.
Based on average capacity factors of 0.15 for solar, 0.25 for wind and 0.75 for geyser-derived geothermal, that represents a total average 'renewable energy' power (excluding biomass) of 40 GW, globally, in 2008.
A similar analysis based on the average energy of each query has been conducted for the QbE STD systems and results are presented in Table 12.
The CC2420, which has become the de facto IEEE 802.15.4 radio chip, measures the RSSI based on the average energy level of eight symbols of the incoming packet.
