to identify important attributes/factors that contribute to grain and biological yields of wheat, 9912 sets of diverse data from field studies were extracted, and supervised attribute-weighting models were employed. results showed that when biological yield was the output, grain yield, nitrogen applied, rainfall, irrigation regime, and organic content were the most important factors/attributes,...

A method is presented for the statistical analysis of sets of data which are assembled from multiple experiments. The analysis recognizes the existence of both within group and between group variabilities, and calculates appropriate weighting factors based on the observed variability for each group. The weighting factors are used to calculate a "best" consensus value from the overall experiment...

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...

Weighting in life cycle assessment (LCA) is a controversial subject due to its dependence upon value judgements. One of the issues that has to be dealt with is whose values that shall be reflected. In a democratic society, a fair candidate to put forward would be the government. In environmental economics taxes and fees set up by governments to protect natural resources and the environment are ...

the aim of this study preparation of the predicted soil maps by using kriging and inverse distance weighting methods in east rangeland of semnan. sampling was done within each unit of sampling parallel transects and 1 vertical transect with 750m length. soil samples were taken from 0-20 cm in starting and ending points of each transect. there were used kriging and inverse distance weighting met...

This paper presents an extended version of Partial Parallel Interference Cancellation (PPIC) called Variance reduced Partial Parallel Interference Cancellation (VRPPIC) for multicarrier code division multiple access uplink systems. The combination of PPIC receiver and new bit estimator is called VRPPIC detector. This realization is derived for the main PPIC operation and soft decision (SD) from...
