Performance monitoring systems are becoming increasingly important in providing Quality-of-Service (QoS) based services and service guarantees. Performance monitoring can occur at different levels and different timescales. Either passive measurements and active measurements can be employed. Currently, a large amount of work has gone into developing mechanisms and protocols for performance and t...

Research suggests that abnormal performance-monitoring contributes to the etiology and maintenance of anxious pathology. Moreover, the anxiety-performance monitoring relationship appears to be specific to the worry dimension of anxiety. Given that anxiety (and worry in particular) is twice as prevalent in women as men, and most studies to date have employed small samples which are underpowered ...

This paper studies the characteristics and behavior of AntNet routing algorithm and introduces two complementary strategies to improve its adaptability and robustness particularly under unpredicted traffic conditions such as network failure or sudden burst of network traffic. Both of the proposed strategies use the knowledge of backward ants with undesirable trip times called Dead Ants to balan...

Whereas several studies have demonstrated that core self-evaluations (CSE)-or one's appraisals about one's own self-worth, capabilities, and competences-relate to job outcomes, less is known about the mechanisms underlying these relationships. In the present study, we address this issue by examining the role of within- and between-person variation in CSE in the relationship between work pressur...

In this article, a new traffic sensing and monitoring technique is introduced which works based on the emitted RF noise from the vehicles. In comparison with the current traffic sensing systems, our light-weight technique has simpler structure in both terms of hardware and software. An antenna installed to the roadside or the inside of a car receives the signal generated during electrical activ...

in many statistical process control applications, the quality of a process is characterized by a profile. a profile is a function in terms of one or more explanatory variables. in profile monitoring, one is interested to monitor the performance of a process or product using this functional relationship. control charts for monitoring nonparametric profiles are useful when the relationship is too...

Aluminium-coated micromirrors driven by electrothermal and electromagnetic actuations have been demonstrated for 3-D variable optical attenuation applications. Three types of attenuation schemes based on electrothermal, electromagnetic and hybrid, i.e. combination of electrothermal and electromagnetic, actuations have been developed. In addition, two different designs have been fabricated and c...

Many novel spatio-temporal applications deal with moving objects. In such environments, a database typically maintains the initial position and the moving function for each object. Instead of updating the database whenever an object position changes (which is not manageable), updates are issued whenever a function parameter (velocity, direction, etc.) changes. For simplicity, we assume that obj...

Distributed applications require timely network measurements so that they can adapt to changing network conditions and make efficient use of grid resources. One of the key issues in obtaining network measurements is the intrusiveness of the measurements themselves—how much network performance is “wasted” taking the measurements? Our goal is to combine active and passive monitoring techniques to...

To support creation of nimble applications for computational grids, the authors believe one must eliminate the barrier that separates program creation from execution and post-mortem optimization. This paper outlines an approach to dynamic performance adaptation and distributed optimization in the grid environment based on a suite of performance instrumentation, analysis, and presentation tools ...
