the experiment was investigated to survey of yield and yield components of sunflower cultivars under drought stress in 2012 in kabootatabad of esfahan farm. an experiment was conducted in split plot and was designed in randomized complete block with three replications. irrigation was as main plots in 3 levels (control (normal irrigation), irrigation of 130 mm evaporation from pan evaporation, i...

Electric vehicles introduce new problems in vehicle route planning. Due to limited battery capacity the fastest route from origin to destination is not always feasible. Existing techniques compute the energy optimal route, however this route is often too conservative in terms of travel time. Optimizing both energy consumption and travel time may allow us to identify routes which are both fast a...

The term ‘Master Data’ brings up different interpretations and connotations, especially with vendors espousing the “single version of the truth”. Is there a single version of the truth? Practical realities suggest that we need to continue to live with existing versions – at least until the “single version” is reached. So how do we handle the co-existence of “multiple versions” of the truth? Thi...

The percepts known variously as the line motion illusion, motion induction, and transformational apparent motion have attracted a great deal of experimental interest, since they sensitively probe interactions between preattentive and attentive vision processes. The present article develops a neural model that qualitatively explains essentially all the data reported thus far, and quantitatively ...

PASM 2004: Performance models for master/slave parallel programs – p.1/22

We present a model based on an O(3) flavor symmetry and a minimal extension of the scalar sector to induce hierarchical breaking, O(3) → O(2) → SO(2) →nothing. The model naturally accounts for all the known lepton parameters and yields various interesting predictions for others: (i) Neutrinos are nearly degenerate, mν ∼ 0.1 eV; (ii) The solar neutrino problem is solved by the MSW small mixing a...

A diastereoselective ring contraction of the diastereomixture of 2,4-disubstituted 1,3-dioxepins to 2,5-cis-2,3,5-trisubstituted tetrahydrofurans was achieved using TfOH in DMF. The reaction appears to proceed via a chair-like transition state, in which stereomutation of the oxocarbenium occurred, followed by an aldol-type cyclization.
