Artificial Neural Networks for Gas Turbine Monitoring

Due to the deregulation of the electricity market the power producers are forced to continuously investigate various means of maintaining/increasing their profits. Improving the electrical efficiency through hardware upgrades is probably the most commonly employed measure, although the interest for enhancements with regard to plant operation is on the rise. Plant operation improvement is often m

Sverige måste bli bättre på att kontrollera dricksvattnet

Styvmoderligt behandlat område. Undersökningar visar att vart tredje svenskt grundvattenprov är förorenat av växtskyddsmedel. Ändå övervakas bara fjorton procent av de svenska grundvattenförekomsterna. Sverige måste agera nu för att få kontroll över situationen, skriver nio forskare och experter.

Raytracing in the compensation of the peripheral optics of the eye

Abstract Background: Many people with a visual impairment have only peripheral vision. However, there is limited knowledge of the peripheral optics of the eye and only some measurements are available in this field. Methods: We simulated the paths of peripheral rays through the eye by means of raytracing. Five programs were compared. The OSLO raytracing software proved to be not only the best one

The solution for Israelis and Palestinians: a parallel state structure

Growing US-Israeli tension over continued East Jerusalem settlement construction – which the White House appears unable to stop – underscores a deeper reality: The two-state solution is no longer possible. What are the alternatives? For the past few years, the idea of a “parallel states” structure has been discussed, suggesting a scenario with a two-states structure on the same land, both states c

The mobile Oracle: a tool for early user involvement

This paper describes a novel tool for eliciting user requirements early in the design process of mobile applications. The "Mobile Oracle", as we have called it, is intended to help developers and designers obtain a better understanding of what the user wants at different points in space and time. It is an extension of a lo-fi version of the well-established Wizard of Oz technique, but it adds an "
