In this paper, we consider energy management algorithms for scheduling jobs in power-scare scenarios such as embedded computer systems and sensor networks. We focus on investigating the impact of buffer resources in minimizing the total energy cost in an online setting. The online algorithms do not have any assumptions on job arrivals; their worst-case performance is measured in term of competi...

 Taxation is one of the significant phenomena in any economy as it not only generates revenues for existing government, but also serves as a fiscal tool and stabilization policy. One of the main types of taxation is the petroleum tax which accounts for more than 30% of revenue for developed countries and more than 85% for developing economies. This work focuses on petroleum producing giants in ...

the limitation of energy resources and its considerable consumption growth in iran has doubled the necessity of optimization and conservation of energy in the country compared to the average consumption rate of energy in the world and also because of high consumption rate's adverse effects in the environment. heating systems are among the main consumers of energy and using a high efficienc...

Power consumption in IP-over-WDM networks has become a major concern, more so due to rapidly evolving data intensive applications. Increasing power consumption also increases the environmental cost (carbon emission). Carbon emissions are the result of power generation using non-renewable (traditional hydrocarbons) energy resources. Usage of non-renewable energy resources (such as hydrocarbons, ...

According to the energy crisis in the world, optimization of energy consumption is indispensable. Technological advances in constructions and application of renewable energy resources demand saving energy. Atrium, as one of the construction elements, catches sufficient daylight and acts as a passive solar element and results in a decline of energy consumption. This research seeks to evalu...

energy and mass transfer investigations in thermal processing of fruits serve as a breakthrough in the design and scale up of drying systems. diffusivity characteristics and specific energy consumption for drying of fig fruit in a laboratory scale microwave dryer were assessed. several intervals for microwave power intensity including 0.5, 1, 1.5, 2, and 2.5 w g-1, and 6 levels of power on-off ...

jujube (zizyphus jujube mill), a valuable medicinal plant, is consumed either as fresh fruit or dried product in iran. drying jujube guarantees a longer shelf time while preserving its quality to be used in medical and pharmaceutical industries. in this research paper, the influence of several drying conditions on the effective moisture diffusivity, activation energy, energy consumption and req...

the rice conversion process is an agricultural transformative industry that consumes a great deal of fossil fuel and electricity. in this study, the effect of different factors on energy consumption, energy consumption index and whitening index were investigated. the experimental design was a split plot design with four whitening periods (15, 30, 45, 60s) (main plot), three rice varieties (khaz...

In this study, the energy consumption of Nasirabad Industrial Park (NIP) treatment plant was evaluated. A combination of up-flow anaerobic baffled reactor (UABR) and aerobic integrated fixed-bed activated sludge (IFAS) processes were employed in NIP. To find out the average electrical energy use per m3 influent wastewater, the rate of energy usage of the plant was calculated by data ...

Integrating natural resources and ecological services in the production process is crucial to implement sustainable agriculture. However, the measurement of natural resource efficiency remains difficult. This paper aims at contributing to this issue, by investigating French farms’ use and excess (slack) of energy resources through Data Envelopment Analyses (DEA). Results show that disentangling...
