Estimating the subjective, human-perceived quality of an image can be very useful. For example, with an accurate measure of how interesting and attractive each photo from an event is we could create high quality, automated slideshows and summaries. Often people take multiple pictures of the same scene, and these quality metrics could also be used for deduplication: once duplicate images have be...

The proliferation of non-linear and time-variant loads is causing a number of disturbances on the electric network, from a more and more significant distortion of both currents and voltages, to transient disturbances on the supply voltage. In this respect the electric network behaves as an "healthy carrier" of disturbances, so that a disturbance generated by one customer can be distributed to o...

This paper analyses our ability to measure software quality. The analysis is based on the representational theory of measurement. We analyse three assumptions on software quality measurement and recommend an increased measurement focus on establishing empirical relational systems (models of what we measure) in software quality related work. Applying measurement theory on the measurement of soft...

Measurement is the basis for assessing potential improvements in healthcare quality. Measures may be classified into four categories: volume, structure, outcome, and process (VSOP). Measures of each type should be used with a full understanding of their cost and benefit. Although volume and structure measures are easily collected, impact on healthcare results is not always clear. Process measur...

Maintenance costs of Information Systems (ISs) are high today and are growing. Part of the costs come from low software quality. The software quality can be measured when it is maintained. By improving the quality of maintenance prone modules future maintenance costs may be curtailed. In this article we will discuss how to measure software quality and we will also present a prototype that has b...

A qualitative assessment of indoors air quality is presented, by the use of an electronic nose consisting of a gas sensor array, a data acquisition system and a pattern recognition system. The gas sensors are sensitive to gases polluting the indoors air but they are sensitive to indoors temperature and humidity as well. The data acquisition system overtakes the sensors specific response and out...
