Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...

Cloud computing offers on-demand, elastic resource provisioning that allows an enterprise to provide services to their customers at an acceptable quality while consuming only the requisite computing resources as a utility. Since cloud computing resources scale elastically, utilizing cloud computing reduces the risk of over-provisioning, wasting resources during non-peak hours, and reduces the r...

In this paper we introduce a Resource Access Management (RAM) framework for resource utilities that facilitates Class of Service (CoS) based automated resource management. The framework may be used to offer resources on demand to enterprise applications that have time varying resource needs. The classes of service include guaranteed, predictable best effort, and best effort. The analytical appa...

in this paper, the residential demand for electricity equation is specified and then this equation is estimated using a pooling data for period 1983-90. the results of study for different regions of province show that the demand is less elastic with respect to average price of electricity and residential area, .but it is more elastic with respect to income and average number of households. thes...

Cloud computing provides the illusion of a seamless, infinite resource pool with flexible on-demand accessibility. However, behind this illusion there are thousands of servers and peta-bytes of storage, running tens of thousands of applications accessed by millions of users. The management of such systems is non-trivial because they face elastic demand, have heterogeneous resources, must fulfil...
