Alerting systems and related decision-making automation are widely used to enhance the safety and capability of controlled processes across many applications. Traditional alerting systems use physical metrics such as temperature, distance between vehicles, or time-to-impact as bases for making alerting decisions. Threshold values on these metrics are typically derived using an iterative process...

A common set of statistical metrics has been used to summarize the performance ofmodels ormeasurements— the most widely used ones being bias, mean square error, and linear correlation coefficient. They assume linear, additive, Gaussian errors, and they are interdependent, incomplete, and incapable of directly quantifying uncertainty. The authors demonstrate that these metrics can be directly de...

Database buffering normally assumes that a proper measure of performance is the number of pages transferred. This paper justifies that the number of I/O’s is the proper unit of measure. From this we derive a buffering policy that improves over known buffering policies for nested loop joins, we derive some buffering policies for hashing joins, and we make an observation about selections and quer...

The process of engineering design involves moving through different levels of abstraction of the design problem and solution. During this cycle, the use of analogies has been shown to be a powerful mechanism for the development of a design solution. These design analogies are often drawn from systems that embody a similar function-flow-performance metric combination. Yet, most existing design t...

Applications that require a robot to cover an area can be described as complete coverage navigation tasks. Examples of this type of navigation are vacuuming, surface coating, and systematic foraging. Performance measures are often neglected in this area of research. This paper presents two metrics for measuring performance of robot coverage tasks and applied them to a real robot coverage experi...

This paper presents the area under the Receiver Operating Characteristics (ROC) curve as an alternative metric for evaluating word sense disambiguation performance. The current metrics – accuracy, precision and recall – while suitable for two-way classification, are shown to be inadequate when disambiguating between three or more senses. Specifically, these measures do not facilitate comparison...

In last few years there has been significant growth in the area of wireless communication. Quality of Service (QoS) has become an important consideration for supporting variety of applications that utilize the network resources. These applications include voice over IP, multimedia services like video streaming, video conferencing etc.. This paper aims on performance Metrics as implemented by Ad...

A statistical approach to performance prediction is applied to a system development methodology for pipelines comprised of independent parallel stages The methodology is aimed at distributed memory machines employing medium grained parallelization The target applications are continuous ow embedded systems The use of order statistics on this type of system is compared to previous practical usage...

Mobile robots navigation involves the design of navigation algorithms. There are several navigation methods for mobile robots and every time a new navigation algorithm is proposed, some comparisons with traditional algorithms are usually made, but there isn’t set of benchmarks globally accepted to assess the performance of algorithms. Despite the wide variety of studies and research on robot na...

Understanding the performance of disaster monitoring systems is a key to understanding their success, therefore; various qualitative and quantitative measures and metrics can be applied in the characterization and analysis of such systems. Through evaluation studies, problems that impede a disaster monitoring system performance can be identified. The results can be used for system control, desi...
