wind power generation is variable and uncertain. in the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. in this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via monte carlo simulation ...

The effect of sugar feeding on egg-batch size in Aedes aegypti was examined in a way that would distinguish between the roles of a recent sugar meal (full vs. empty crop) and of repeated sugar feeding and digestion (high vs. low energy reserves). Egg numbers of females representing the four combinations of these characteristics (full crop/high reserves, full crop/low reserves, empty crop/high r...

due to easy availability of cheaper raw material and increase in new applications, the use of polyolefins in variousindustries is becoming a major priority. the middle east region, on account of its vast oil and gas reserves has,in the last decade or so, been developing many new petrochemical complexes with their expansion into colossalpolyolefin production capacities. the predictions are that ...

Nonfeeding postlarval pueruli of spiny lobsters migrate tens of kilometers across the continental shelf to settle in coastal waters. A model that analyzes hydrodynamic forces during swimming in the puerulus of Jasus edwardsii is described. The model calculates the speed at which forward propulsion balances drag. Calculated speeds agree with observed puerulus behavior. The computed mechanical wo...

Indonesia has vast solar energy potential, far more than needed to meet all its requirements without the use of fossil fuels. This remains true after per capita consumption rises match developed countries, and most functions are electrified minimize Because relatively small potential from hydro, wind, biomass, geothermal ocean energy, it will rely mostly on for sustainable needs. Thus, require ...

We fed broad-tailed hummingbirds (Selasphorus platycercus) diets of contrasting carbon isotope composition and measured changes in the delta(13)C of expired breath through time. By measuring the delta(13)C in the breath of fed and fasted birds we were able to quantify the fraction of metabolism fueled by assimilated sugars and endogenous energy reserves. These measurements also allowed us to es...
