abstract due to limited water resources in agriculture, application of each strategy to economize water use and increase area under cultivation is very important. one such strategy is deficit irrigation. for optimal planning of deficit irrigation, it is necessary to determine different sensitive stages of plant water shortages. in this study the effect of deficit irrigation on growth and yield ...

abstract icssdom is a mathematical synthetic model that was written with fortran77 and in which used sa simulation annealing algorithm like an internal loop in basic structure of icss hydrodynamic simulation model. this model presented by mohseni movahed in 1381. this model is able assess current performance and present optimal operation considering downstream requirement of turnout in real con...

background: we aimed to assess the high-risk group for suicide using different classification methods includinglogistic regression (lr), decision tree (dt), artificial neural network (ann), and support vector machine (svm). methods: we used the dataset of a study conducted to predict risk factors of completed suicide in hamadan province, the west of iran, in 2010. to evaluate the high-risk grou...

introduction: detection of caries lesions on approximal surfaces of posterior teeth is difficult, since wide contact points hamper direct visual inspection. due to the importance of the early detection of dental caries, the aim of this study is to compare the performance of different methods (visual, bitewing radiography and diagnodent) in detecting approximal caries in primary molars. methods:...

In this study, we construct a transcription start site (TSS) prediction model using the logitlinear model and the genomic context features mined in promoter regions. We also develop a computational program named ProKey that is able to accurately predict TSSs in long DNA sequences. Performance evaluation results on the whole human genome show that ProKey could achieve 71.2% sensitivity and 76.3%...

Digital computing devices have a finite precision. Hence when digital controllers are implemented, there is rounding on the variables and parameters resulting in the various finite-word-length effects on the closed-loop stability and performance of the system. In this paper we concentrate on the coefficient sensitivity problem. That is: to determine the controller realization that minimizes the...

sensitivity analysis to determine variations in evapotranspiration is much important considering a known variation in one of climatic variables. in this study, sensitivity of evapotranspiration from penmann-mantith, penmann-kimberly (1996), penman-kimberly (1972) and penmann (1984)  and hargrivs (1985) approaches to three climatic variations (maximum temperature, wind speed, solar radiation) wa...
