the aim of this paper is to project extreme precipitation events in an arid and a semiarid station. in order to project climate change based on general circulation models (gcms), we have applied lars-wg[1] downscaling tool. this stochastic weather generator down-scaled the climate of two synoptic stations using hadcm3 model and a2 emission scenario for 2040. we extracted extreme precipitation e...

We propose an incentive pay scheme for educators that links educator compensation to the ranks of their students within appropriately defined comparison sets. Because this scheme employs only ordinal information, it allows education authorities to employ new assessments at each testing date without ever having to equate various assessment forms. Thus, our scheme mitigates incentives for teacher...

Four algorithms for percentile filtering are compared. The ways they can be implemented in hardware and software, their flexibility and their speed are taken into account.
