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.

The swedish healthcare is in many situations one of the best in the world. But still, the healthcare system includes elemnts that reduce the efficiency. Partly becouse the swedish healthcare is largely monopolized, the servicecs are not properly prized and the economic responsibility and the liability legislation is limited. The main problem this study evolves around, is how a different liability rule would change the shape of the healthcare organisation. Abouve all, how would the approach to riskmanagement and preventive and riskreducing performance change with a diffrent liability rule.

The demand for shorter lead-times and increased delivery reliability puts pressure on companies to provide more efficient logistic services. One strategy to deal with this demand is by outsourcing logistics to a third part. The development of logistics information systems enables increased control over business supply chains. This is why Green Cargo aims to create a Logistics Control Tower (LCT) solution to provide it?s customers with better information with higher availability.

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.

The focus of this thesis is primarily in electronic construction and describes the design process for a microcontroller circuit board from concept development to prototyping. The client develops test fixtures for automated testing of products within the electronics industry and needs a new controller circuit for the test fixtures that can handle controls and basic testing. An investigation into the needs of such a system is conducted and a prototype printed circuit board assembly is manufactured.The prototype is developed with focus on protection against electrostatic discharges and overvoltage. Among the functions that are included are voltage measurements, communication interfaces and control of input and output currents. Firmware for the prototype is developed and configured to communicate with a PC through USB interface for control and collecting of measurements..

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.

This study revolves around calculating the extent of appearance of both anonymously and named men and women as well as determining whether or not Yvonne Hirdman?s gender theory is applicable on two versions of a Swedish educational history textbook called Epos: historia: för gymnasieskolans kurs A (2008) and Epos [historia] 1b (2012), published for two different curriculum. Our qualitative investigation of two parts of the book?s content proves that the two principles of gender system are present in both books, although to a lesser extent in the latter version. Calculating the material, results have shown that anonymous men and women are almost equally presented in Epos 2012, which is not the case in the 2008 version.

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.

Sweden?s District councils and Country councils are in itself to a large extent responsible for the state financed welfare. Because of this, Sweden has a contribution- and adjustment system. The reason for this system is to create equal chance, for all District councils and Country councils, to be able to give the citizens service independently of their income and non-influential structural differences. The adjustment is built upon the so-called standard cost method, which contains four different parts.

It?s been noted that cows held at the section of ruminant medicine and epidemiology, Swedish University of Agricultural Sciences (IME), used for the education of veterinary students, have a lower heart rate than what is considered normal for ruminants. In this investigation the heart rates of seven lactating cows were recorded continuously during the period around drying off. The first recording took place at the farm from where the cows were bought, and then their heart rate was monitored after their arrival at IME and further on until they were completely dried off. The results were then compared to the heart rate of seven already dried off cows from the same farm.

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.
