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.

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

On November 1st 2010 the obligatory audit was removed in Sweden for small companies. What factors influence such companies to have their financial reports audited, and what factors exert the strongest influence. Purpose: The authors would like to investigate factors that affect companies with voluntary audits in Skåne län to continue with the audit. The authors also wish to examine the factors that have the strongest impact on the choice to adopt auditing. Method: A quantitative study has been conducted in which aquestionnaire was sent to companies in Skåne Län Conclusion: The factors that affect smaller companies to continue with audit are as follows: Accounting quality, cost, creditors (loans), suppliers / customers, the tax office and distort competition.

The inherited education and the (un)free choice?- A comparative survey between five different programs on University of ÖrebroThe aim with this paper has been to examine and to report for different sociocultural background factors (class property, the parents' level of education, the parents' income) importance for the choice of type of education and to see if there is any differences between different university courses with respect to class property. Our issues were following:1. What/which sociocultural factors have had most importance for the choice of programs on universities?2.

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 aim of this study was to investigate how four families in the Stockholm area reason, what kind of preconception they have and what their horizon of expectations is when they make the choice between sending their children to the profile class of municipal/free schools and sending them to the general classes in those schools. The main research questions asked were:What kind of preconception do the parents have about profile classes?What reasons do the interviewed parents have to send their children to a profile class?What are the interviewed parent?s expectations of the profile class choice?The study is built on qualitative interviews with the parents of the families. The empirical data has been analyzed using a framework of theories drawing on the theory of reproduction, the forms of social capital, the ideas created from the word profile and elite and the horizon of expectations. The results show that the parents of the families have a similar degree of preconception about profile classes.

This study examines if there are any behavioural differences in-store between consumers who choose a healthy product and consumers who choose a regular product. 540 observations were conducted were different variables were studied. Tthe results indicate that there are some variables that show a significant difference in behaviour at the point of choice between consumer who choose healthy products and those who choose regular products..

The aim of this paper is to examine how The Swedish Library Classification System, also known as the ?SAB-system?, has classified popular music. The investigation is limited to the classification category of ?Yx Jazz, Rock and Popular Music? within the SAB-system. The development of this category is studied.

Denna explorativa studie beskriver hur den interna kontrollen i organisationer kan påverkas under implementeringen av ett ERP system. Intern kontroll är en del av organisationens ekonomistyrning och består av organisationens rutiner och aktiviteter för att undvika risker och säkerställa att organisationens mål uppfylls. Eftersom implementeringen av ett ERP system är en riskfylld process är det viktigt att förstå hur den interna kontrollen påverkas. För att undersöka detta används i studien ramverket Internal Control - Integrated framework. Datainsamlig genomfördes på en stor IT-organisation där ERP systemet Navision 2009 implementeras och 10 respondenter från olika avdelningar intervjuades.

Sekretessbelagd.

Det pågår en transformering av svenska stridskrafter till följd av en förändradomvärldsbild och en teknisk utveckling. Obemannade farkoster studeras och bedömskunna tillföra värdefulla förmågor.Syftet med uppsatsen är att undersöka nyttan med små UAV-system för bataljonsnivånvid en internationell militär operation. De fyra utvalda basfunktionerna ledning,underrättelser, verkan och skydd utgör analysfaktorer.Uppsatsens resultat omfattar en kontextuell del och en teknisk del. Den omfattar även envärdering av små UAV-system i ett typfall, strid i bebyggelse. Uppsatsen visar att detfinns ett flertal uppgifter inom basfunktionerna, som små UAV-system kan lösa medvarierad förmåga.
