the hop-normalized metric is better able to route real time traffic away from congested links thus providing better performance to satisfy real time services requirements.

Scalability and performance are critical quality attributes of applications developed for the cloud. Many of these applications have to support hundreds or thousands of concurrent users with strongly fluctuating workloads. Existing approaches for software performance evaluation do not address the new challenges that arise for applications executed in cloud computing environments. The effects of...

Images and videos are subject to a wide variety of distortions during acquisition, digitizing, processing, restoration, compression, storage, transmission and reproduction, any of which may result in degradation in visual quality. That is why image quality assessment plays a major role in many image processing applications. Image and video quality metrics can be classified by using a number of ...

This paper proposes a simulation framework called the loading region for the performance evaluation of admission control policies for high speed networks. The loading region provides a means to assess the performance characteristics of an admission control policy in terms of its sensitivity to traac mix, traf-c characteristics, cell loss constraints, and cell delay constraints. The loading regi...

We propose the use of clustering methods in order to discover the quality of each element in a training set to be subsequently fed to a regression algorithm. The paper shows that these methods, used in combination with regression algorithms taking into account the additional information conveyed by this kind of quality, allow the attainment of higher performances than those obtained through sta...

the effect of different levels of wood betony (wb), stachys lavandulifolia extract, as complement in feed, on the performance of common carp, cyprinus carpio was evaluated. the fish (44±0.62 g) was assigned to four treatments, three replicates each. the fish was fed on normal diet with no wb (control) vs. diet containing 2, 4 and 8% of wb extract. fish were successively fed on the diet, 2% live...

this study had been performed to analyzing relationship between performance management and service quality because of develop the banks service quality by means of improve specific sides of the performance management. the pma method was used for analyzing the performance management at isfahan melli bank and the systra-sq scale was used for assessing the service quality at there. in order to rel...

conclusions regarding the study findings, there was a significant difference between family function dimensions and quality of life among addicts and non-addicts. results the study revealed that some disorders in family function dimensions were higher in the addicts compared to non-addicts. addicts have a quality of life lower than non-addicts (p < 0.05). there was a relationship between differ...

in the first experiment, the chemical composition, apparent metabolizable energy (ame), ame corrected for nitrogen (amen), true metabolizable energy (tme), tme corrected for nitrogen (tmen) values of the sweet almond meal were determined in adult leghorn cockerels. the second experiment was performed to evaluate the effects of different levels of sweet almond meal at 0, 100, 200 and 300 g/kg on...
