Thermographic phosphors thermometry was used to measure engine valves and transparent piston temperatures in two dimensions as well point wise of a running, optically accessible, gasoline direct injection engine. The engine, fueled with isooctane, was operated in continuous and skip-fire mode at 1200 and 2000 rpm. A calibration of the phosphorescence lifetime and spectral properties against temper

Recently, Burger et al. (2011) developed a new 1-D SST model which allows for more realistic predictions of the sludge settling behaviour than traditional 1-D models used to date. However, the addition of a compression function in this new 1-D model complicates the model calibration. This study aims to report advances in the calibration of this novel 1-D model. Data of the evolution of the sludge

Ett av underlagen till Lunds universitets utvecklingsprojekt EQ11 utgjordes av en undersökning av samspelet mellan examensmålen för forskarutbildningen och bedömningens utformning vid ett eller flera forskarutbildningsämnen från varje fakultet/område. Undersökningen utfördes under perioden februari-april 2011 och innebar att varje fakultetsledning utsåg de ämnen som skulle ingå. Redovisningen bygg

Retrieval orientation describes the modulation in the processing of retrieval cues by the nature of the targeted material in memory. Retrieval orientation is usually investigated by analyzing the cortical responses to new (unstudied) material when different memory contents are targeted. This approach avoids confounding effects of retrieval success. We investigated the neural correlates of retrieva

The paper addresses some key problems that arise in applications of adaptive control to industrial processes, prior knowledge, design based on simplified models, initialization and start up. Different ways of solving the problems are discussed. A new technique for automatic tuning of simple control loops is presented. The method has the advantage of automatically generating test signals whose prop

The concentrations of sulfur and several more elements were measured in a network of six sites in southern Sweden. High time resolution samples were taken using a continuous filter sampler and analysed by particle induced X-ray emission (PIXE). Simultaneous increases in the sulfur concentrations were seen along the network due to the inflow of polluted air masses. High sulfur concentrations genera

In this seminar paper, I attempt an in-depth analysis of a collection of articles published in historical periodicals in Finland 1990-2000. My main interest concerns how the writers – mainly professional historians, representatives of scientific ideals of their age – discussed the idea of the Finnish nation during this decade, and how these discussions reflect a certain understanding of the work o

Problem statement. Despite their success-story, neural networks have one major disadvantage compared to other techniques: the inability to explain comprehensively how a trained neural network reaches its output; neural networks are not only (incorrectly) seen as a “magic tool” but possibly even more as a mysterious “black box” [1]. This is an important aspect of the functionality of any technology
