The position and orientation estimation problem for mobile robots is approached by fusing measurements from inertial sensors, wheel encoders, and a camera. The sensor fusion approach is based on the standard extended Kalman filter, which is modified to handle measurements from the camera with unknown prior delay. A real-time implementation is done on a four-wheeled omni-directional mobile robot, u

In this paper a novel method to make reconstruction from any number of uncalibrated cameras is presented. The novelty lies in the fact that the algorithm relies only on subspace methods, which implies that it is independent of the chosen coordinate system in the images. Furthermore, it does not distinguish between the dioeerent points in each image and can deal with any number of images and points

An intuitive and appealing way to characterize problem solving is as the application of constraints which reduce the problem-solution space. Any advantage offered by interdisciplinary problem solving would then plausi- bly derive from the integration of constraints from the fields involved. We propose an account of interdisciplinary problem solving which treats the integration of constraints as an

Respiration in animals, plants and many bacteria is dependent on heme A, which functions as a prosthetic group in a-type cytochromes (terminal energy-transducing oxidases in the electron transport chain that reduce molecular oxygen to water). Heme A synthase catalyses a chemically very demanding reaction, the conversion of one specific methyl side-group of heme O to a formyl group of heme A. This

Kartellbekämpningsutredningen lämnar i delbetänkandet förslag beträffande villkor och former för nersättning av konkurrensskadeavgift, ökat sekretesskydd, kriminalisering och rättegångskostnader i konkurrensärenden. Utredningens förslag om villkor för nersättning av konkurrensskadeavgift är väl avvägda, överensstämmer med internationell praxis på ett till svenska förhållande anpassat sätt. Fakulte

In a joint project between the Swedish Civil Aviation Administration (SCAA) and Lund University, questions concerning organizational aspects - such as organizational climate, team climate, situational leadership, psychosocial working environment - and safety culture are under study. A team-based organization has recently been introduced and a new air traffic control system will soon be installed a

The legislated goals for Master of Science in Engineering educations include goals like having the ability to critically, independently and creatively identify, formulate and handle complex problems as well as participate in research and development work and thus contribute to knowledge development. One might therefore argue that these educations are required to promote a deep approach to learning
