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.

Den här studien syftar till att klargöra hur gymnasieelevers inlärningsstrategier är relaterade till deras förmågor. Förmågorna synliggjordes som intelligensprofiler baserat på Gardners teori om multipla intelligenser. Att åka med logiktåget definieras som att förstå logik så att det i varje nytt avsnitt i matematik eller fysik endast är den nya logiken som behöver förstås. Studien genomfördes med en enkätundersökning samt med uppföljande intervjuer. Resultaten visar att elever med lägre logisk-matematisk intelligens än lingvistisk intelligens använder ytinlärning eller procedurmemorering och därmed missar delar av logiken i matematik och fysik.

The “peer to peer” (P2P) is a technology of downloading and filesharing between online - Internet - users by the mean of specified software. Since June 1999, the Napster software has made the happiness of millions of individuals who used it to obtain and share free audio files Mp3. Rapidly, the major recording companies have prosecuted the Napster Company and managed to force it to close down. They were arguing against it for it is supporting the development on a large scale traffic of files protected by copyright and thus was threatening the whole music and movies economic world. Since fast Internet connections multiplied, "peer to peer" software and networks improved, so that this mode of exchange became an unprecedented success. Today all cultural products, in particular films and music, are concerned with this free –of– charge distribution without any financial counterpart for the copyright holders. Two tools hold today the top ranks and concentrate large traffic: eDonkey and eMule.

The main purpose in this degree thesis is to investigate changes in performance when introducing a newly produced Real-Time database in one of CC Systems products, the Diagnostic Runtime Engine, DRE. The thesis is a collaboration between CC Systems, creator of DRE, and Mimer AB, developer of the Real-Time database.The result reveals that the time spent on database access is considerably lesscompared to the originally used database. The research has lead to several additional requirements on the real-time database and these are presented as part of the result in this thesis. The additional features will help making the product more suitable for DRE and similar applications.Additional research is required to be able to recommend the use of this product or not. Primarily the performance in another operating system, Windows CE, but also the introduction of additional features should be investigated.

The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..

The purpose of this study was to investigate if female and male reporters and interviewees get the same amount of time in the news feature in the Swedish news programs TV4-Nyheterna and SVT 1 Rapport. The aim of this study was also to investigate if there is a breakdown of the reporting lines between male and female reporters, that is, if they are reporting on various topics. In our study we also determined if the two television channels in any way are different when it comes to gender.Our main theory was that men are overrepresented both among reporters and interviewees and that they are dominant in both hard and soft news. We thought that SVT 1Rapport would have a better gender balance than TV4-Nyheterna because SVT 1 has been working on gender issues for a long time.We were using a quantitative content analysis to examine the 19:30 news on SVT 1 Rapport and 22:00 news on TV4-Nyheterna for two weeks in November 2010. We examined domestic and foreign news and determined how much time each sex got.

Bakgrund: Cirka 60 % av alla människor upplever ryggsmärtor med eller utan ischiasproblem under sin livstid. En buktande disk kan orsaka svår smärta. Den kliniska diskbråcksdiagnostiken är god och behandlingen oftast konservativ. Trots det är radiologiska undersökningar med MRT vid diskbråcksdiagnostik mycket vanligt förekommande.Syfte: Syftet är att undersöka nyttan med en magnetisk resonanstomografiundersökning vid diskbråcksdiagnostik.Frågeställningar: Stämmer fynden, funna vid en MRT undersökning med den kliniska bilden hos diskbråckspatienter? Vilken ytterligare information ger den radiologiska, MRT undersökningen utöver den kliniska undersökningen vid diskbråcksdiagnostik? Metod: Detta är en litteraturstudie som inkluderar tolv, vetenskapliga artiklar.

During 2010, 1446 people committed suicide in Sweden. Research shows that groups that are less favored in society have an increased risk of suicide. Social services often encounter groups of people that have a high risk of suicide, for instance welfare recipients or substance abusers. The purpose of this study was to shed light on how social workers talk about suicide and how this might affect interactions with suicidal clients. The study is based on qualitative interviews with five social workers in Stockholm.

This master thesis was done for a company called BRUKS which is active in woodprocessing,bio-energy and bulk material handling industry. The idea for the master thesis wasto develop a new reclaiming method for silos where wood chips are being stored. A mediumsegment of between 1000 ? 5000 m3was defined as the segment with the most sales potential.Two different concepts were produced, one for new constructions and one for rebuildingalready existing silos.In the beginning of the master thesis a lot of time was spent on visiting different BRUKSoffices and customers to get an overview of the industry and the product. This informationwas the basis when the idea generating phase began.
