With more and more mission‐critical networking‐intensive workloads being virtualized and consolidated, virtual network performance has never been more important and relevant than today. VMware has been continuously improving the performance of its virtual network devices. VMXNET Generation 3 (VMXNET3) is the most recent virtual network device from VMware, and was designed from scratch for high ...

In this paper we present an Algebraic Language which allows us to describe probabilistic and non-deterministic processes as well as to evaluate index performances: PPNAL (Performance Probabilistic and Non-deterministic Algebraic Language). We also analyse the Alternating Bit Protocol by using this language, showing the average time to send a message , taking into account that channels may fail ...

Maintaining a headquarters is the backbone of corporate operations. The enhancement of a headquarters’ performance may significantly contribute to the performance improvement and revenue growth of the entire corporation. It is especially important to develop a performance evaluation model for headquarters in this era of profit squeeze. As the saying goes, “You can’t manage it until you can meas...

This paper is aimed at evaluating the performances of different measures which have been proposed in literature for robust matching. In particular, classical matching metrics typically employed for this task are considered together with specific approaches aiming at achieving robustness. The main aspects assessed by the proposed evaluation are robustness with respect to photometric distortions,...

An intention to adopt IP protocol for future mobile communication and subsequent extension of Internet services to the air interface calls for advanced performance modeling approaches. To provide a tool for accurate performance evaluation of IP-based applications running over the wireless channels we propose a novel cross-layer wireless channel modeling approach. We extend the small-scale propa...

Global clustering has rarely been investigated in the area of spatial dambase systems although dramatic performance improvements can be achieved by using suitable techniques. In this paper, we propose a simple approach to global clustering called cluster organization. We will demonstrate that this cluster organization leads to considerable performance improvements without any algorithmic ovedxa...

In this paper, an overview and a benchmark of some semi-active suspension control strategy performances is proposed. Based on a recent result of the authors, where the optimal semi-active performance trade-off was addressed, here, a complete benchmark to evaluate any controlled semi-active suspensions is proposed, and applied on different control approaches. The present paper aims at providing ...

control and evaluation are major secrets of an organization's survival.universities, as research and educational organizations, need to be evaluated in order to survive. the results of educational activities encompass a vast spectrum including the graduates, researchers and planners, scientific publications, as well as satisfaction of students, parents, profossors and staff (ramsden, 1996).th...

background the critical role that the board plays in governance of universities clarifies the necessity of evaluating its performance. this study was aimed to evaluate the performance of the boards of medical universities and provide solutions to enhance its performance.   methods the first phase of present study was a qualitative research in which data were collected through face-to-face semi-...
