The need for calculating actions has been emerged everywhere and in any time, by advancing of information technology. Cloud computing is the latest response to such needs. Prominent popularity has recently been created for Cloud computing systems. Increasing cloud efficiency is an important subject of consideration. Heterogeneity and diversity among different resources and requests of users in ...

We will present progress on work to add cloud condensate control variable to a 4D-VAR analysis system at ECMWF. First, in 4D-VAR the linear physics scheme needs prognostic cloud variables to be able to use additional cloud information from observations, and in the current phase of our development the additional prognostic variable is cloud condensate (cloud liquid water and ice). Second, it is ...

We present new observations of a 2 field in the north-eastern spiral arm of M31. In the 0.8 × 3.6 kpc mosaicked region, we have detected six distinct, large complexes of molecular gas, most of which lie along the spiral arm dust lane or in the vicinity of HII regions. The mean properties of these complexes are as follows: D∼57±13 pc, ∆V∼ 6.5±1.2 km s, MCO∼3.0±1.6 ×10 5 M⊙, peak brightness tempe...

The use of radiative kernels to diagnose climate feedbacks is a recent development that may be applied to existing climate change simulations. We apply the radiative kernel technique to transient simulations from a multithousand member perturbed physics ensemble of coupled atmosphere-ocean general circulation models, comparing distributions of model feedbacks with those taken from the CMIP-3 mu...

in this work, we developed a simple and selective method for separation and spectrophotometric determination of trace amounts of cetylpyridinium chloride (cpc) in pharmaceutical products using cloud point extraction (cpe) technique. the method is based on cloud point extraction of the cpc in alkali conditions using of nonionic surfactant triton x-114. under selected conditions, the calibration ...

cloud computing is the latest technology that involves distributed computation over the internet. it meets the needs of users through sharing resources and using virtual technology. the workflow user applications refer to a set of tasks to be processed within the cloud environment. scheduling algorithms have a lot to do with the efficiency of cloud computing environments through selection of su...
