seasonal variations of climatic parameters are significant in arid and semi-arid regions and sensitivity of each parameter may differ in different seasons. no work has been done in this regard in iran. therefore, in this study, sensitivity analysis of the asce-penman-monteith grass reference evapotranspiration (eto) equation was investigated on the basis of variation of mean air temperature (tm...

Neural networks for estimation, such as the multilayer perceptron (MLP) and functional link net (FLN), are shown to approximate the minimum mean square estimator rather than the maximum likelihood estimator or others. Cramer-Rao maximum a posteriori lower bounds on estimation error can therefore be used to approximately bound network training error, when a statistical signal model is available ...

We prove new cell-probe lower bounds for dynamic data structures that maintain a subset of {1, 2, ..., n}, and compute various statistics of the set. The data structure is said to handle insertions non-adaptively if the locations of memory accessed depend only on the element being inserted, and not on the contents of the memory. For any such data structure that can compute the median of the set...

Abstract Land-atmosphere interactions play an important role in the changes of extreme climates, especially hot spots land-atmosphere coupling. One linkages is coupling between air temperature and surface energy fluxes associated with soil moisture variability, vegetation change, human water/land management. However, existing studies on are mainly based parameterized solution climate model, whi...

We report a study of the magnetoresistance (MR) of the metallic perovskite oxide LaNiO3−δ as a function of the oxygen stoichiometry δ (δ ≤ 0.14), magnetic field ( H ≤ 6T ) and temperature (1.5K ≤ T ≤ 25K). We find a strong dependence of the nature of MR on the oxygen stoichiometry. The MR at low temperatures change from positive to negative as the sample becomes more oxygen deficient ( i.e, δ i...

The paper ‘‘Mean Distance and Minimum Degree,’’ by Mekkia Kouider and Peter Winkler, JGT 25#1 (1997), 95–99 mistakenly attributes the computer program GRAFFITI to Fajtlowitz and Waller, instead of just Fajtlowitz. (Our apologies to Siemion Fajtlowitz.) Note also that one of the ‘‘flaws’’ we note for Conjecture 62 (that it was made for graphs regular of degree d, vice graphs of minimum degree d)...

BACKGROUND Although the effects of meteorological factors on the general population health are widely documented, little is known about their influence on human pregnancy and birth. The present study aims at analyzing the influence of the atmospheric conditions on premature births. METHOD One hundred and eight nine cases of premature births were included in the study, with a gestational age b...

Brown eye spot (Cercospora coffeicola) is one of the main fungal diseases coffee, leading to a significant drop in crop productivity and beverage quality Brazil. The identification potential risk areas for development disease provides promising information management pathogen. This study aimed elaborate an agroclimatic zoning incidence brown on coffee under climate change scenarios, as suggeste...
