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 urban land management is an l part of the urban management. In some countries such as Iran, there is no integrated urban land management and providing municipal services is assigned to nationwide organisations. This means urban management is offered by the municipality or subsidiaries of the aforementioned organisations such dispersion has occurred during serval decades. It is considered as...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
an improved model of mud dispersion has been introduced in this work. the advantages of this model consist of a new analytical correlation for dispersivity by using resistivity log data and using a new aspect of capacitance dispersion model. mathematical formulations were expressed, solved by numerical model taking advantage of actual log and formation data. achieved results yielded reasonable ...
nowadays, air pollution is one of the main challenges worldwide. there have been significant improvements in air quality dispersion modelling. aermod is one of these models which is based upon the gaussian model. however, aermod has some limitations in terms of data input and output. therefore improving this model as well as developing new models adopted to our country is required to be address...
EXTENDED ABSTRACT The end user requirement for this development is to be able to assess the impact of land use changes on groundwater quality, specifically that due to nitrate leaching from agriculture. Implementation will be for alluvial plains at scales up to about 2000 km. GIS databases provide information on land use and soils. This information, at individual field and farm scale, enables m...
over-exploitation of groundwater resources in Chaharmahal va Bakhtiari province led to prohibition of some plains in this province. One of these plains is Sefiddasht aquifer. Artificial recharge can be an effective method to raise the groundwater table and resolve the groundwater crisis in this province. The most important step for successful accomplishment of artificial recharge is locating su...
