The paper addresses two issues: (i) modeling dynamic flows transmitted in vast TCP/IP networks and (ii) the impact of energy-saving algorithms. approach is based on fluid-flow approximation, which applies first-order differential equations to analyze evolution queues flows. We demonstrate that effective implementation this method overcomes constraints storing large data numerical solutions tran...

Many species hibernate to conserve energy during periods of low food and water availability. It has long been assumed that the optimal hibernation strategy involves long, deep bouts of torpor that minimize energy expenditure. However, hibernation has ecological (e.g. decreased predator avoidance) and physiological (e.g. sleep deprivation) costs that must be balanced with energy savings; therefo...

Energy metabolism and its relation to survival of the infective juveniles (IJ) of S. carpocapsae under anaerobic and oxygen-deficient conditions were studied by monitoring changes in survival rate, levels of key energy reserve materials, oxygen consumption, and respiratory quotient (RQ). The effects of various factors on the survival of IJ under anaerobic conditions were also investigated. Unde...

Recently, the Korean government has been carrying out projects to construct several large scale horticulture facilities. However, it is difficult for an energy supply to operate stably and economically with only a conventional fossil fuel boiler system. For this reason, several unused energy sources have become attractive and it was found that power plant waste heat has the greatest potential f...

Active participation of demand-side resources in power system control tasks, i.e., demand response, is expected to facilitate the integration of renewable energy sources in the grid. In this paper, we present a novel hierarchical control scheme to enable provision of frequency control reserves by a pool of office buildings managed by an aggregator. The reserves are provided by controlling the c...

Due to increasingly expansion of energy consumption and also decreasing and tendency towardsending fossil energy reserves, the current energy cycle needs to use alternative energy speciallywind energy, because it’s considerably cheaper than other recycling sources. The present researchinvestigates possibility of creating wind Power Station economically at Soltanieh zone of Zanajnprovince regard...

The increasing penetration of renewable energy in recent years has led to more uncertainties in power systems. In order to maintain system reliability and security, electricity market operators need to keep certain reserves in the SecurityConstrained Economic Dispatch (SCED) problems. A new concept, deliverable generation ramping reserve, is proposed in this paper. The prices of generation ramp...

As widely distributed vast reserves of emerging green energy, solar energy has gained widespread attention in recent years. Photovoltaic (PV) power generation is one the most scientific ways to use energy. In PV systems, polyethylene terephthalate (PET) chief material backsheets. It well known that backsheets will encounter various challenges, among which partial discharge (PD) these cause dete...

Thiobencarb and propanil are two of the most extensive used herbicides worldwide in rice cultivation. Especially scanty is the available information regarding the effect of herbicides on fish energy resources. In the present study, the effect of sublethal exposure to these herbicides on the energy reserves of juvenile eel Anguilla anguilla was compared. Eels were exposed to 72 h to the herbicid...

Among the many biological responses studied in ecotoxicology, energy-based biomarkers such as digestive enzyme activities and energy reserves appear to be useful predictive tools for detecting physiological disturbances in organisms. However, the use of these biological responses as biomarkers could be limited by the effects of confounding factors (biotic and abiotic) and physiological processe...
