OBJECTIVES The aim of this article was to identify and prospectively investigate simulated ultrasound-guided targeted liver biopsy performance metrics as differentiators between levels of expertise in interventional radiology. METHODS Task analysis produced detailed procedural step documentation allowing identification of critical procedure steps and performance metrics for use in a virtual r...

Wireless Intrusion Detection System (IDS) performance metrics are used to measure the ability of a wireless IDS to perform a particular task and to fit within the performance constraints. These metrics measure and evaluate the parameters that impact the performance of a wireless IDS. Wireless IDS analyze wireless specific traffic including scanning for external users trying to connect to the ne...

This document lays out a framework by which defensible performance metrics for oil spill response can be developed in an analytic-deliberative process that includes a broad range of stakeholders and is informed by high quality scientific knowledge. Performance metrics can be used to: improve oil spill response planning, promote institutional learning post-response, support public communication ...

The Telecollaboration (TC) business system, an important class of emerging applications that is spawning new challenges to achieving the desired levels of performance. One important implication in identifying and characterizing the properties of TC system implementations is that performance evaluation should no longer be isolated and viewed as a separate analytic activity. Instead, we require a...

In multihop wireless networks experience frequent link failure caused by channel interference, dynamic obstacles, and bandwidth demands. Because of this degradation the wireless networks require expensive manual network management recovery. This paper presents an autonomous network reconfiguration system (ARS) using AOMDV protocol and acknowledgement reception .The ARS enables the multi radio, ...

Providing Quality of Service (QoS) is a major challenge in wireless networks. In this paper we propose a distributed call admission control protocol (DCAC) to do both bandwidth and delay guaranteed call admission for multihop wireless mesh backbone networks, by exploiting the multi-channel multi-radio (mc-mr) feature. We propose a novel routing metric for route setup, and present an efficient d...

Workflows provide an expressive programming model for fine-grained control of large-scale applications in distributed computing environments. Accurate estimates of complex workflow execution metrics on large-scale machines have several key advantages. The performance of scheduling algorithms that rely on estimates of execution metrics degrades when the accuracy of predicted execution metrics de...

Metrics and measures for physical phenomena are precisely defined and widely accepted. However, metrics and measures for intelligent systems are as yet vaguely defined and controversial. Even the definition of intelligence is not widely agreed upon. A number of metrics and measures have been developed for measuring human performance in scholastic aptitude, athletic ability, and task performance...

We present a learning framework for fusion-based video retrieval system, which explicitly optimizes given performance metrics. Real-world computer vision systems serve sophisticated user needs, and domain-specific performance metrics are used to monitor the success of such systems. However, the conventional approach for learning under such circumstances is to blindly minimize standard error rat...
