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 ...

because of the role of climate parameters in climate change and improve the efficiency of climate and rainfall prediction models, the study of these parameters are very important in the world. the study of clouds have special important, because the clouds make connection between the synoptic patters and surface climate conditions and any change in its properties, can start a chain reaction in o...

cloud computing refers to services that run in a distributed network and are accessible through common internet protocols. it merges a lot of physical resources and offers them to users as services according to service level agreement. therefore, resource management alongside with task scheduling has direct influence on cloud networks’ performance and efficiency. presenting a proper scheduling ...

Infrastructure-as-a-Service is the most flexible form of cloud computing and provides great opportunities to acquire and release computing resources as necessary. However, consumers face an increasingly opaque market due to growing number of providers and tariff options. As an approach to aid consumers finding the right tariff matching their needs, we suggest a broker model as an intermediate b...

in this article cloud-point extraction (cpe) was used with chelating agent to extract uranium from aqueous solutions. the methodology used is based on the formation of metal complexes soluble in a micellar phase of surfactant. the metal ions complexes are then extracted into the surfactant-rich phase at a temperature above the cloud-point temperature. the effect of type of surfactants and ligan...

The ability to measure the energy consumed by cloud infrastructure is a crucial step towards the development of energy efficiency policies in the cloud infrastructure. There are hardware-based and software-based methods of measuring energy usage in cloud infrastructure. However, most hardware-based energy measurement methods measure the energy consumed system-wide - including the energy lost in...
