Popular Abstract in Swedish Nästa år är det 400 år sedan Galileo Galilei för första gången riktade ett teleskop mot objekt på himlen. Allt sedan dess har teleskopet varit det viktigaste instrumentet för astronomins utveckling och med dess hjälp har vår kunskap om universum revolutionerats. Tack vare utvecklingen av teleskopet under dessa århundraden har allt ljussvagare objekt kunnat studeras, ochThis thesis presents the work on the design of, construction of, and finally observations with, an experimental setup comprising a small telescope equipped with adaptive optics. The facility has been assembled at Lund Observatory, where also observations on the sky have been made. The aim of this project was to gain hands-on knowledge in the development of a real adaptive optics system and eventua

Disturbances on utilities, such as steam and cooling water, often cause large revenue losses at industrial sites. These disturbances are often hard to handle, since they commonly are plant-wide disturbances that affect more than one production area at the site. Also, the production areas of the site are often dependent on other production areas because of the flow of product through the site, whic

Abstract in UndeterminedNanoindentation has recently gained attention as a characterization technique for mechanical properties of biological tissues, such as bone, on the sub-micron level. However, optimal methods to characterize viscoelastic properties of bones are yet to be established. This study aimed to compare the time-dependent viscoelastic properties of bone tissue obtained with different

A number of techniques have been proposed to provide run- time performance guarantees while minimizing power consumption. One drawback of existing approaches is that they work only on a fixed set of components (or actuators) that must be specified at design time. If new components become available, these management systems must be redesigned and reimplemented. In this paper, we propose PTRADE, a n

There are many reasons why heat transfer and heat exchangers play a key role in the development of sustainable energy systems as well as in the reduction of emissions and pollutants. In general, all attempts to achieve processes and thermodynamic cycles with high efficiency, low emissions, low costs include heat transfer and heat exchangers to a large extent. It is known that sustainable energy de

The benefits of integrating a real-time oriented language for description of control algorithms, PAL, into a package for computer aided control system design, SIMART, are investigated. An anti-wind-up partial state model reference controller, designed and validated in this environment, has been successfully tested in real-time on a double tank system.
