“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

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.

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.

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

I skönlitterär prosa förekommer det strängt taget enbart tre olika temporala texttyper: narration (berättande text, relation), citat (alltså dialog) och berättarens nutid (dvs. passager där en berättare talar i egen sak), och det finns bara två finita tempus att välja emellan: presens och preteritum. Det kan tyckas som om de skönlitterära författarna har ett snävt spelrum att operera inom. Men det

A Vernier Gate-Ring-Oscillator (GRO) Time to Digital Converter (TDC) is proposed and implemented in 90-nm CMOS process technology. It utilizes two GRO chains as the delay lines. The time resolution is determined by the difference between two delays, so not limited by the process. Moreover, the quantization noise can be first-order shaped by the gated behavior in the oscillators, which further impr

Within the framework of a Swedish national experiment with different types of Intelligent Speed Adaptation, 300 vehicles are being equipped with an active gas pedal in the city of Lund. The active gas pedal provides drivers with counter-force whenever they try to exceed the pre-set speed limit. During the experiment the equipment will be continuously set on the actual speed limit. The vehicles wil

Untripped sport utility vehicle rollovers are dangerous and possibly lethal accidents. A new kinetic energy based measure, that indicates an imminent wheel lift-off, is introduced. This measure is used by a gain scheduled linear quadratic (LQ) controller to prevent wheel lift-off. The LQ controller outputs the desired changes of the forces acting on the chassis. These force changes are mapped to b
