In this paper we present a modification of the Dual Priority Scheduling Algorithm to work on shared memory multiprocessor systems improving the average-case schedulability. The proposal deals with global fixedpriority preemptive scheduling of periodic tasks on identical processors. The algorithm allows to schedule hard real-time periodic tasks using task migration between different processors. ...

Interhemispheric interaction in mathematically gifted (MG) adolescents, average-ability (AA) youth, and college students (CS) was examined by presenting hierarchical letter pairs in 3 viewing conditions: (a) unilaterally to the right hemisphere (RH), (b) unilaterally to the left hemisphere (LH), or (c) bilaterally, with 1 member of the pair presented to each hemisphere simultaneously. Participa...

Since air temperature records are readily available around the world, the models based on air temperature for estimating solar radiation have been widely accepted. In this paper, a new model based on Hargreaves and Samani (HS) method for estimating monthly average daily global solar radiation is proposed. With statistical error tests, the performance of the new model is validated by comparing w...

Given a constraint satisfaction problem (CSP) on n variables, x1, x2, . . . , xn ∈ {±1}, and m constraints, a global cardinality constraint has the form of ∑n i=1 xi = (1−2p)n, where p ∈ (Ω(1), 1−Ω(1)) and pn is an integer. Let AV G be the expected number of constraints satisfied by randomly choosing an assignment to x1, x2, . . . , xn, complying with the global cardinality constraint. The CSP ...

[1] Model results and observations both indicate warming of the world ocean from 1955 to 2003. Forced by reanalysis data, the model also shows that the warming of the arctic ice–ocean system is faster than the global average since the 1960s; there is a small but widespread increase in heat content of the Arctic Ocean’s waters and a larger increase of latent heat embodied in the ocean’s decreasi...

AIMS To make quantitative estimates on a global basis of exposure of disease-relevant dimensions of alcohol consumption, i.e. average volume of alcohol consumption and patterns of drinking. DESIGN Secondary data analysis. MEASUREMENTS Level of average volume of drinking was estimated by a triangulation of data on per capita consumption and from general population surveys. Patterns of drinki...

The Water and Global Change (WATCH) project evaluation of the terrestrial water cycle involves using land surface models and general hydrological models to assess hydrologically important variables including evaporation, soil moisture, and runoff. Such models require meteorological forcing data, and this paper describes the creation of the WATCH Forcing Data for 1958–2001 based on the 40-yr ECM...
