The Network Simulator-3 (ns-3) is rapidly developing into a flexible and easy-to-use tool suitable for wireless network simulation. Since energy consumption is a key issue for wireless devices, wireless network researchers often need to investigate the energy consumption at a battery powered node or in the overall network, while running network simulations. This requires the underlying simulato...

steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...

Background: Car wash wastewater contains several contaminants such as organic matter, oil, grease, detergents and phosphates, all of which are harmful for the environment. In this study, the application of electrocoagulation (EC) to treat car wash wastewater has been studied, and the operating parameters optimized. The electro-Fenton (EF) for further contaminant removal was also investigated. ...

in this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between t6 and l2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. all subjects walked at their preferred speed on a figureof- eight track. normal subjects also walked at slower and faster speeds. oxygen consumption, heart rate and rating of perceived exertion were measured. in norm...

this paper investigates the possibility of both linear and nonlinear effects of energy consumption on economic growth in iran, using data for the period of 1959–2007 based on threshold regression. some previous studies support the view that energy consumption may promote economic growth. however, the conclusion drawn from this study suggests that such relationship exists only where there is a l...

in the recent years, renewable energy sources are an important component of world energy consumption. gdp is one of the main measures of a country’s economic activity. most of the studies examine the impact of renewable energy consumption on gdp with single equation model and the others use dynamic panel data. since the granger causality analysis’s findings of this paper establish bidirectional...

today, one of the biggest problems that gripped the banking sphere, the high cost of implementing advanced technologies and the efficient use of the hardware. cloud computing is the use of shared services on the internet provides a large role in developing the banking system, without the need for operating expenses including staffing, equipment, hardware and software reducing the cost of implem...

these days, limited energy resources, and also the cost of investment in new and renewable energy is very costly and uneconomical. in the industrial sector, especially energy-intensive industries such as steel, finding appropriate solutions to update the technology, production and reduce energy consumption in this sector is very important. the main aim of this study is the identification and ra...

sustainability in 19 different arab countries has been studied through investigating the relationship between economic development and energy consumption. data collected has been studied as a whole (total countries data) and as segregated data (oil exporting and oil importing countries data) i.e. three categories. the regression model used measures the effect of independent and control variable...

energy consumption has been essential to societies; because societies depend on the rising provisions of energy to meet their requirements for goods and services and endorse sustainable development. the major source of energy nowadays is oil; oil consumption is dependent on oil availability, production and price. several arab countries are considered as major suppliers of oil in the world; cons...
