Level density and level density parameter in medium heavy nuclei including thermal and quantal fluctuation effects Abstract In a realistic application of the SPA + RPA theory for calculation of the nuclear level densities we find that quantal fluctuation corrections (RPA) are important even up to temperature T = 2.0 M eV. This leads to a good agreement between calculated numbers and the availab...

Today’s motivation for autonomous systems research stems out of the fact that networked environments have reached a level of complexity and heterogeneity that make their control and management by solely human administrators more and more difficult. The optimisation of performance metrics for the air traffic management system, like in other networked system, has become more complex with increasi...

As software production achieves a growing importance in the embedded systems world, quality evaluation of embedded software and its impact on physical properties of embedded systems becomes increasingly relevant. Although there are tools for embedded software design that improve software specification and verification, we are still short of a tool that supports the designer’s decisions on the b...

System performance analysis is typically conducted by collecting structured data in the form of metrics or by examining unstructured data in the form of logs. Tools currently available either analyze the structured data or the unstructured data, but not both. In some settings, this is not enough to make meaningful statements about the performance of the system. In this work, we explore alternat...

The widely-used automatic evaluation metrics cannot adequately reflect the fluency of the translations. The n-grambased metrics, like BLEU, limit the maximum length of matched fragments to n and cannot catch the matched fragments longer than n, so they can only reflect the fluency indirectly. METEOR, which is not limited by n-gram, uses the number of matched chunks but it does not consider the ...

1 This research was supported in part by the DARPA Next Generation Internet (NGI) program and the NSF Information Technology Research (ITR) grant no. 0121546. Abstract Out of order arrival of packets is an inevitable phenomenon on the Internet. Application performance can degrade to a great extent due to out-of-order arrival of packets. Metrics to characterize the degree of re-ordering will pro...

Detecting the densest subgraph is one of the most important problems in graph mining and has a variety of applications. Although there are many possible metrics for subgraph density, there is no consensus on which density metric we should use. In this paper, we provide formal guidelines to choose an appropriate density metric using four axioms. These axioms capture the necessary conditions any ...

Cloud computing is a promising concept for the implementation of scalable on-demand computing infrastructures, where resources are provided in a self-managing manner based on predefined customers requirements. A Service Level Agreement (SLA), which is established between a Cloud provider and a customer, specifies these requirements. It includes terms like required memory consumption, bandwidth ...
