The development of software-intensive systems is driven by their requirements. Traditional requirements engineering (RE) methods focus on resolving ambiguities in requirements and advocate specifying requirements in sufficient detail so that the implementation can be checked against them for conformance. In an ideal world, this way of thinking can be very effective. Requirements can be specifie...

The small-scale industries (SSIs) have a direct relevance for national and local socioeconomic development. However, SSIs that use fossil fuels also contribute not only local pollution, but also greenhouse gas (GHGs) emissions that are associated with the global problem of climate change. Select cleaner technologies can help not only in reducing local pollution and GHG emissions, but also provi...

Cleaner organisms exhibit a remarkable natural behaviour where they consume ectoparasites attached to "client" organisms. While this behaviour can be utilized as a natural method of parasitic disease control (or biocontrol), it is not known whether cleaner organisms can also limit reinfection from parasite eggs and larvae within the environment. Here we show that cleaner shrimp, Lysmata amboine...

A novel air-cleaner with a coil-shape photocatalysis-plasma synergistic reactor was developed. The air-cleaner showed 95% ± 1% reduction of a TVOCs concentration in tobacco smoke at “single-pass” condition. Air-purification activity of the air-cleaner was stably-maintained after the treatment of 12,000 cigarettes of tobacco smoke.

In this paper we report our study on the user experience of robot vacuum cleaner behaviour. How do people want to experience this new type of cleaning appliance? Interviews were conducted to elicit a desired robot vacuum cleaner personality. With this knowledge in mind, behaviour was designed for a future robot vacuum cleaner. A video prototype was used to evaluate how people experienced the be...
