The injury risk for bus passengers is low compared to car users. However, bus passengers also run the risk of sustaining injuries as vulnerable road users: as pedestrians or cyclists to and from the bus stop. Among vulnerable road users, seniors are a particularly important group. Hitherto, injury data have mainly been based on police-reported accidents. These accidents reveal bus occupant safety,
With a broad approach it is possible to see the importance of the many parts in the whole, and to grasp the cultural situations that surround reading in combination with travel. Interaction and co-production are of great importance. Fiction influences reality, which in turn influences the fiction, which in turn… and so on. Fiction can function as an optical lens for reality. The difference between
The lidar group in Lund has performed many DIAL measurements with a mobile lidar system that was first described in 1987. The lidar system is based on a Nd: YAG-pumped dye laser. During the last few years the lidar group has focused on fluorescence imaging and mercury measurements in the troposphere. In 1994 we performed two campaigns: one fluorescence imaging measurement campaign outside A vignon
Popular Abstract in Swedish Många har frågat mig vad mitt doktorandprojekt egentligen handlar om. Mitt svar brukar variera beroende på hur insatt personen ifråga är. Normal brukar jag börja med ungefär följande förklaring: I våra kroppar finns proteiner som hjälper till att utföra och reglera kemin som krävs för att hålla de biologiska processerna igång. Att förstå denna kemi kan vara till hjälp Accurate calculation of energies for protein reactions is a hard problem. There are many reasons for wanting to calculate these energies, e.g. ligand design and the study of enzyme reactions. There are two major problem involved in these kinds of calculations. First, the large number of local minima in proteins introduces uncertainties when studying single structures. Second, the size of proteins
Many problems in computer vision, such as stereo, segmentation and denoising can be formulated as pseudo-boolean optimization problems. Over the last decade, graphs cuts have become a standard tool for solving such problems. The last couple of years have seen a great advancement in the methods used to minimize pseudoboolean functions of higher order than quadratic. In this paper, we give an overvi
