Street lighting, as the most essential and universal component of urban lighting system, accounts for a large portion public electricity usage. Therefore, improving street lamps working efficiency is vital energy savings. This paper demonstrates design smart system supported by combination NB-IoT LoRa communication technology. By adopting an optimized lamp control algorithm, can realize automat...
In this study, the impact of technological improvement and depletion in upstream sector on the average cost of oil and gas production in Iran is studied in 1967-2017. For this purpose, global technology diffusion trend is calculated, so five variables that have had the most effect on global upstream is considered. Using acquired trend for technology and taking other related determinants into ac...
Biofloc technology (BFT) is a relatively new biotechnological means to support high density culture, maintain water quality, biosecurity, reduce the need for water exchange, reutilize the feed and reduce the production cost. This technology is mainly based on the principle of waste nutrients recycling (particularly nitrogen) into microbial biomass that can be used in situ by the cultured animal...
this paper presents an economic evaluation of gas to liquids (gtl) project using “south-pars” gas field of iran based on the latest actual performing gtl projects. iran has the world’s largest reserves of natural gas and can satisfy the projected long-term market demand of gtl products which have lower pollution and higher quality than refinery products. the results of cost-benefit analysis sho...
introduction: intraoperative radiation therapy device (iort) is one of the several options for partial breast irradiation. iort is sent to the tumor bed during surgery and can be replaced with conventional standard therapy (ebrt). the aim of this study was to evaluate the safety and effectiveness of iort machine compared with ebrt and to determine the dominant option in terms of the cost-effect...
background: eos is a 2d/3d muscle skeletal diagnostic imaging system. the device has been developed to produce a high quality 2d, full body radiographs in standing, sitting and squatting positions. three dimensional images can be reconstructed via stereos software. this health technology assessment study aimed to investigate efficacy, effectiveness and cost-effectiveness of new emerged eos imag...
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...
