Inom styr- och reglerteknik är hantering av larm en viktig fråga, speciellt då fastighetsbranschen mer och mer börjat automatisera driften av fastigheterna. Det finns ett antal system på marknaden som erbjuder larmdistribution via en mängd olika transportsystem. Syftet med projektet är att undersöka om det finns alternativ till dessa som erbjuder mer flexibilitet, samt att designa en prototyp till ett system som använder denna alternativa metod. Två befintliga system analyserades och en kravspecifikation baserad på analysen upprättades. Utifrån denna designades en prototyp som sköter distributionen över Internet och en enkel implementation av en del av designen har gjorts.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

Detta examensarbete är det avlutande momentet på civilingenjörsutbildningen Ergonomisk design och produktion vid Luleå tekniska universitet. Målet med projektet är att designa en helt ny skotermodell exteriört. Tyngdpunkten i projektet är utseendet men även andra aspekter behandlas, så som ergonomi, materialval och tekniska lösningar. En Internetbaserad enkätundersökning, marknadsundersökning samt systematisk problembehandling ligger till grund för designen av fyra grundkoncept. Dessa undersöks genom strukturerat konceptval samt samråd med uppdragsgivaren.

Den pågående utvecklingen med informationssystem och den ökade tillgången till information via dessa system ökar kraven på den militära personalen att hantera denna stora mängd information.Information om aktörer i ett stridsområde samt den terräng aktörerna befinner sig i är en förutsättning för att genomföra militära operationer. Som följd av denna informationsmängd behöver informationssystemen utvecklas för att kunna ge bättre beslutsunderlag.Syftet med uppsatsen är att undersöka vilken militär nytta man skulle kunna uppnå med ett geografiskt informationssystem (GIS) för beslutsfattarna i en militär insats. Dessutom skall uppsatsen undersöka hur ett GIS bör vara utformat för att stödja personalen med beslutsfattande.Undersökningen sker genom både komparativ litteraturstudie och beskrivning av teorier och metoder.Resultatet pekar på att GIS bör kunna bidra till den militära nyttan med att möjliggöra ett informationsöverläge gentemot en motståndare. Vidare pekar resultaten på att rätt design på GIS underlättar för användaren men att det ändå krävs utbildning för att nyttja GIS fullt ut..

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

Detta arbete är utfört hos Videum AB i Växjö i syfte att visa på skillnader i energiförbrukning mellan deras ventilationssystem samt hur lång tid det skulle ta för en möjlig investering i ett nytt ventilationssystem att återbetala sig.För att uppnå detta utfördes beräkningar på olika faktor som bidrar till den totala energianvändningen hos ventilationssystemet. I denna undersökning behandlas fläktar, golvaggregat och värmeförluster genom ventilation. Den största påverkande faktorn i den totala energiförbrukningen är värmeförluster genom ventilation.Resultatet av vår undersökning visar att det är billigare att använda i VAV-system än ett CAV-system under rådande förhållanden enligt våra beräkningar. En årlig besparing på 29465 kronor per våning vid byte från CAV-system till VAV-system uppnås. Det är värt att byta ventilationssystem även fast att investeringskostnaden inte sparar in sig under dess livstid.

In Sweden the breeding organization for the Swedish Warmblood horse uses a traditional scoring system when evaluating horses. The horse is scored subjectively in relation to how good each trait is in relation to the breeding objective. Other countries, for example the Netherlands, instead use a linear scoring system. The linear scoring system evaluates the horse on a scale between two, for the breed, biological extremes which makes the evaluation more objective since the judges personal values does not influence as much. The breeding organization for the Swedish Warmblood is today planning a change towards a linear scoring system.

The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..

The objective of this Bachelor?s thesis is to investigate how the public library in Luleå has set about implementing an alternative classification system for its children's books section and to explore why this was done. We wanted to investigate both how they have adapted the new system to the children's own way of seeking information and the library personnel's experience of using the new shelving system. We have done seven interviews to answer these questions and our choice of literature is intended to put the process of change into a wider context. The answers show that the library was dissatisfied with the former system and have instead expressed a desire to shift the focus of their classification system to their users.

Bakgrund och problemdiskussion: Under årens gång har det inträffat flera företagsskandaler. Det har sett bra ut på ytan men insidan har visat motsatsen. Fasaden kollapsar till följd av bristande kontroll. Intern styrning och kontroll och COSO:s Internal Controll ? Integrated Framework blir allt mer aktuellt för att få ordning och reda.

The purpose of this essay is to examine wage-earners' investment funds from the ideological point of view. Were they in any way an integrated part of social democratical democratic socialism and reformism? I emphasize Olof Palme´s ideological idea of democratic socialism and reformism, and how he handled the issue. How did the question of these funds correspondent with the basic ideological points of view, and what was the standpoint of Palme in this issue.My method is built upon a deep study and analyses of SAP board of party and the standing committees protocol in the light of Olof Palme´s and SAP's ideology. I even use information from literature, inquiries and dissertations.

This study focuses on the politics around ecological sustainable development in Sweden today, with emphasis on urban development, building and living. The starting-point for this study is the environmental adapted city district of Stockholm, Hammarby Sjöstad. The primary focus of the study is to investigate what means of control the environmental investment in Hammarby Sjöstad is expressing, and to elucidate their ideological, political and social implications. The empirical material is primarily based up on the local Hammarby Sjöstad environmental program along with qualitative in-depth interviews with citizens of this district. The study is based on critical discourse analysis The result of this study is that the ecological investment in Hammarby Sjöstad partly constitutes a hidden exercise of power, taking shape as built-in physical measures in the dwellings and the neighbouring surroundings.

The purpose of the study was to investigate how inventories of suspected polluted areas as a part of the planned control of existing companies cab be designed in order to achieve as great effect as possible. The study was conducted in cooperation with Piteå municipality. An analysis of regional inventory projects, local municipal strategies and a pilot study in Piteå was conducted. The experience from both the regional projects and the pilot study was that in order to achieve an effective control a number of factors were inportant: an efficient selection of companies, a good dialogue between the controlling agency and the companies, sufficient resources, education of municipal inspectors and guidance for decisionmaking. Another inportant result was that the municipal planning can prevent an efficient inventory if the control of city development projects is allowed to take time from the planned control.

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.
