Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.

The last few decades the development in the field of electronics has been huge. The components performance gets better at the same time as the manufacturing cost decreases. Many of the design moments that have to be done, are done automatically today, but it can get better. Especially for analog circuit design.At Electronic System in Linköpings universitet, research is in progress to develop a tool that can design analog circuits in reasonable time. It means that it has to size the components (transistors, resistances, capacitances etc), so that the circuit can fulfill the performance requirements.

The purpose of this essay was to examine the different aspects of motivational work with active heroin-using clients from a social workers point of view. The further purpose of this essay is to also examine what the advancements and discouraging factors in such a motivational work might be. To attain this purpose we focused on these following questions:What might motivational work with active heroin-using clients look like?According to the social worker, what factors constitutes for a beneficial progress in the engagement of motivational work with active heroin-using clients?According to the social worker, what constitutes for discouraging factors in the engagement of motivational work with active heroin-using clients?We chose to do a qualitative study by conducting separate interviews with six social workers working in a social services agency, all of whom are working with drug-addicted adults. We then analyzed the answers by using an abductive research strategy, testing the collected empirical data against our chosen theoretical perspectives.

Den här rapporten täcker ett examensarbete som gick ut på att kartlägga och utvärdera användarfilosofin i ROS som utvecklas av Sandvik Systems Development. ROS, RåvaruOptimeringsSystem, används som stöd till produktionen på Sandvik AB:s stålverk. Det primära målet som sattes upp för arbetet var att visa om det går att skapa en koppling mellan ROS och Sandviks Active Directory för att på så sätt slippa skilda lösenord mellan systemen. Rapporten följer arbetet från att ta fram modeller av nya metoder för användarhantering till implementering av några prototyper i en testmiljö. Rapporten tar även upp vilka nya metoder och tekniker som måste skapas för att en fullständig implementation av systemlösningen ska kunna göras..

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

Being physically active is important for a healthty lifestyle, but what do the girls who have quit playing sports in an atheltic club do afterwards, or the girls who are not active within an athletic club what so ever. It is the girls who are not active in an athletic club that Karlstad municipality wants to attract to the spontaneous sports sites there are within the city limits. They also want the girls opinion on how to improve the sites in order for the girls to want to go there.The purpose with this study was to investigate this. This study used qalitative research method. The study interviewed seven girls aged 14-17 years.

De inhysningssystem som används idag möter inte alltid hästens naturliga behov. En traditionell uppstallning hindrar hästen att utföra sitt naturliga rörelsebehov. Genom att ge hästarna möjlighet till mer rörelse kan man få flera hälsomässiga fördelar. Exempel på fördelar är ett starkare skelett, starkare senor, bättre kondition och minskad stress vid uppstallning och träning. Syftet med denna studie är att ta reda på om hästar rör sig mer beroende på olika inhysningssystem som ger olika förutsättningar för rörelse.

ABSTRACTBackground: On behalf of the Orthopedic clinic, Västerås, a study has been conducted with focus on comparing the results after conservative and surgical treatment due to complete achillestendon rupture.Aim: To compare results when testing the active and passive range of motion, calf muscle endurance, estimation of pain related to the achillestendon and self-efficacy to be physically active for individuals who have undergone conservative or surgical treatment after complete achillestendon rupture.Method: 14 individuals afflicted by complete achillestendon rupture in 2010 were recruited as a purposive sample. Examination were conducted of: Ankle range of motion with a goniometer, calf muscle endurance through a toe-raise test, estimation of pain intensity related to the achillestendon by VAS and self-efficacy to be physically active through ?Exercise self-efficacy scale?. P-value and the median were calculated.Result: The results of ankle range of motion and calf muscle endurance were based on the difference between the injured and the healthy side. When testing active plantarflexion the conservative group had a median of 4 ? and the surgical group had a median of 10 ?.

The main aim of this study is to determine whether the monastery in Ny Varberg has been used as a hospital during its active years. The second aim has been to investigate weather the buried individuals at the monastery at Ny Varberg exclusively are deceased monks. Only individuals from the monastery's active years has been included in this study. A total of 16 inhumated individuals was analysed. Both men, women and children was shown to be present, as well as wide spread of children and adults.

The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.
