Many address lookup methods for an IP router have been recently proposed to improve a packet forwarding capability, but their performance prediction is very limited because of lack of considering actual traffic characteristics. It is necessary to consider actual traffic to predict more realistic performances on routers, specially in case of layers 3 and 4 switches whose performances are more in...

The aim of this study was to track and analyze the 200-m Freestyle performance stability throughout elite swimmer’s career. 29 Portuguese male top-50 were analyzed for seven consecutive seasons between 12 and 18 years old. Best performances were collected from ranking tables. Longitudinal assessment was performed based on two approaches: (i) mean stability was analyzed by descriptive statistics...

One human factors challenge is predicting operator performance in novel situations. Approaches such as drawing on relevant previous experience, and developing computational models to predict operator performance in complex situations, offer potential methods to address this challenge. A few concerns with modeling operator performance are that models need to realistic, and they need to be tested...

—One of the key features of the Media Independent Handover (MIH) framework, introduced by the IEEE 802.21 standard, is the support for events, including network degradation events which can be triggered based on link layer metrics and propagated to upper layer mobility protocols. As a framework, MIH does not provide specifics on how these events are triggered. Typically events are triggered whe...

MOTIVATION Optimizing HIV therapies is crucial since the virus rapidly develops mutations to evade drug pressure. Recent studies have shown that genotypic information might not be sufficient for the design of therapies and that other clinical and demographical factors may play a role in therapy failure. This study is designed to assess the improvement in prediction achieved when such informatio...

In this paper, we describe a compilation system that automates much of the process of performance tuning that is currently done manually by application programmers interested in high performance. Due to the growing complexity of accurate performance prediction, our system incorporates empirical techniques to execute variants of code segments with representative data on the target architecture. ...

In this paper, we introduce a hierarchical framework for the quantitative performance evaluation of mobile-agent middleware platforms. This framework is established upon an abstraction of the typical structure of mobile-agent systems and is implemented through a set of benchmarks, metrics, and experimental parameters. We implement these benchmarks on three mobile agent platforms (Aglets, Concor...

In Intelligent Tutoring Systems, adaptive sequencers can take past student performances into account to select the next task which best fits the student’s learning needs. In order to do so, the system has to assess student skills and match them to the required skills and difficulties of available tasks. In this scenario two problems arise: (i) Tagging tasks with required skills and difficulties...

The World Wide Web displays characteristics that make accurate performance prediction impossible. This paper relates performance engineering concepts and practice to an HCI notion of temporal response. In particular, it explores the notion of temporal interaction error and attuning, and presents two examples that serve as a vehicle for the exploration of this domain. The paper concludes with pr...

Media Independent Handover (MIH) is an emerging standard which supports the communication of network-critical events to upper layer mobility protocols. One of the key features of MIH is the event service, which supports predictive network degradation events that are triggered based on link layer metrics. For set route vehicles, the constrained nature of movement enables a degree of network perf...
