Reducing fossil energy resources and increasing greenhouse gases necessitate the need of clean sources of energy. One of the sources of renewable energy is wind power which has been developed in recent years. Sometimes, wind power in peak hours does not respond. Hence, a storage system and backup power for such power plants seem necessary. In this study, a hybrid system, consisting of electroly...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
In order to minimize the social and environmental concerns arising from the use of traditional energy resources such as fossil fuels and nuclear energy, the South Korean government has attempted to develop alternative energy resources. In particular, the large educational institutes and islands in South Korea—which have the motivation and potential to provide electrical services—are required to...
on this project we try to calculated power of hydrogen on dycarbonil compound in different ways ; the first way is shoster way , for sain power of hydrogen notice the different power between central conforms on it and main conform that’s didn’t have hydrogen joint . or in other way different of energy between open and close form. second way, is average way? this is for way that studied conf...
Bondan Hamlet is a hamlet in Kampung Laut District, Cilacap. One of the community's problems lack clean water and PLN electricity network. In 2020, desalination facility named Sidesi Mas will be built with capacity 240 liters/hour using reverse osmosis principle. The energy source for uses solar power plant (PLTS). Desalination management requires economic analysis, especially determining selli...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
چکیده نمایشگاه های جهانی یا اکسپو عنوانی ست که از سال 1851 میلادی در لندن توسط همسر ملکه انگلستان شکل گرفت ، هدف اولیه این نمایشگاه ها نمایش دستاورد های صنعتی بود، اما در طول 165 سال که این نمایشگاه های برگزار گردیدند ، رویکرد آنها تغییر کرده است . در هر دوره به یک شعار که در واقع دغدغه اصلی جهان، در آن زمان بوده است ، پاسخ داده شده و راه حل کشور های مختلف در مورد آن موضوع به نمایش گذارده شد...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...
