چکیده
The ‘nanotechnology’ concept first captured the world’s attention when the Nobel Prize winner Richard Feynman advocated the possibility of widespread nanotechnology research by delivering his famous speech, “There’s Plenty of Room at the Bottom” just half a century ago. The emerging nanotechnology field comprises one of the fastestgrowing research and development (R&D) areas in the world (National Science and Technology Council, 2006). Developed countries, as well as many developing countries, have prioritized nanotechnology as a core scientific and technological research agenda since the early 2000s. R&D activities in nanotechnology have been strengthened worldwide recently to provide a foundation for technological advancement, since governments of many countries have invested aggressively in the relevant research through academic funds and subsidies for private ABStrAct

متن کاملComparison of Artificial Neural Network, Decision Tree and Bayesian Network Models in Regional Flood Frequency Analysis using L-moments and Maximum Likelihood Methods in Karkheh and Karun Watersheds
Proper flood discharge forecasting is significant for the design of hydraulic structures, reducing the risk of failure, and minimizing downstream environmental damage. The objective of this study was to investigate the application of machine learning methods in Regional Flood Frequency Analysis (RFFA). To achieve this goal, 18 physiographic, climatic, lithological, and land use parameters were ...
متن کاملAnalyzing Iran’s Local and Regional Droughts Using the Theory of Runs and Standardized Precipitation Index (SPI)
The primary objective of the present study is the investigation of the various properties of Iran’s local and regional droughts based on the theory of runs and standardized precipitation index (SPI). Thus, in order to accomplish this goal, the annual precipitation data of 63 synoptic stations were procured from Iran’s meteorological organization for a 30-year period (1986-2015).. First, based o...
متن کاملتخمین دبی سیل با تناوب مختلف در حوضه آبخیز زاینده رود طبق روش منطقه ای هیبرید
Designers of hydraulic structures are often faced with the problem of estimating flood frequencies at stream sites, where little or no flow information is available. A regional regression model is widely used which relates physical and climatological parameters to flow characteristics. In this study, a new method is used which is based on the station-year technique and combined records for seve...

متن کاملAn Investigation and Comparison of Road Transport Indicators among the Provinces of Iran
One of the major obstacles in the process of national development, is the disruption in regional balance construct. As has been noted in some studies the existence of regional inequity leads to domination of some regions to surrounding regions and causing political and economic challenges in developing countries. And given that transportation is one of the components of region, undoubtedly equi...
