On the dependence of the laser-induced incandescence (LII) signal on soot volume fraction for variations in particle size

“The laser-induced incandescence (LII) signal is proportional to soot volume fraction” is an often used statement in scientific papers, and it has – within experimental uncertainties – been validated in comparisons with other diagnostic techniques in several investigations. In 1984 it was shown theoretically in a paper by Melton that there is a deviation from this statement in that the presence of

Investigation of the Effects of Leaching on the Scaling Resistance of Concrete

Damage to the concrete surface can be observed at the waterline of hydraulic structures in fresh water bodies in cold climates. Gradual deterioration of the concrete surface leads to exposure of coarse aggregate. Superficial damage at the waterline is commonly assumed to be caused by drifting ice floes. However, deterioration of concrete at the waterline may also involve leaching and frost action.

Hopp, trots allt

This article discusses the German-Swedish author Peter Weiss and his book "Die Ästhetik des Widerstandes" (The Aesthetic of Resistance), and argues for hope, after all.

Template-Based Design Analysis – An Alternative Approach for the Engineering Designer to Perform Computer-Based Design Analysis

Popular Abstract in Swedish Vid framtagning av nya produkter måste man utgå ifrån de behov som den blivande kunden ställer i form av krav och önskemål på produkten för att den ska vara intressant att inhandla och använda. För att säkerställa att den blivande produkten har de egenskaper som efterfrågas, används idag omfattande simuleringar av den blivande produktens egenskaper. Simuleringar består The current trend in industry to encourage engineering designers to take an active part in the analysis of their own design solutions is apparent in many companies today, domestically as well as abroad. From a research project with the objective to develop a computer-based design system for the design of lightweight grippers, one of the major difficulties was to overcome the system users’ lack of
