â the prediction of maximum temperatures as one of the most important climatic parameters due to climate change, global warming and the recent drought will provide definitely more opportunity for planning and the provision of necessary arrangements for the planners. maximum temperatures are much important in management of natural and water resources, agriculture, development of pests and disea...
One of the main causes of air pollution in the arid areas of world, especially in Iran, is the increase of the PM10 concentration. The main objective of this research is to identify the most important climatic factors affecting the change of PM10 concentration near Yazd-Ardakan plain and its relation with wind erosion occurrence during the period from 2012 to 2017. For this purpose, the monthly...
Result: All patients had symmetric, natural osteotomy lines, and satisfactory facial ratios in a single-stage operation. The average relative error of VSP and post-op result on the entire skull was 0.41 ± 0.13 mm. The average new left gonial error(Go’-L Error) was 0.43 ± 0.77mm. The average new right gonial error(Go’-R Error) was 0.45 ± 0.69mm. The Average pognion error(Pg error) was 0.79 ± 1.2...
in this study, the performance of aquacrop model to predict yield production of winter wheat (roshan and gods varieties), water and solute balance of soil profile was evaluated under water and salinity stresses. field experiments were conducted with three levels of saline irrigation water including: s1, s2 and s3corresponding to 1.4, 4.5 and 9.6 ds/m, respectively, and four levels of irrigation...

Background: Magnitude, rate and frequency of the stochastic and unexpected events are of great significance and importance in hydrology. Nowadays, for economic planning of the projects, the use of analytical methods of unexpected events in hydrology is unavoidable. The aim of this study was to compare hybrid regression and multivariate regression to estimate flood peak discharge in the province...
background: municipal solid waste (msw) is the natural result of human activities. msw generation modeling is of prime importance in designing and programming municipal solid waste management system. this study tests the short-term prediction of waste generation by artificial neural network (ann) and principal component-regression analysis. methods: two forecasting techniques are presented in...
