Överföring av elektrisk signal och effekt med magnetisk induktion.

This report tested the possibility of using induction as a mean for transferring data and power so that it can be implemented as a communication medium between a terminal and measuring head mounted in a measuring frame. This would eliminate the need for the cable bunches that are used today. For testing, signal generators were used to generateFSK-signals and were transferred with the help of inductors to the oscilloscope for signal detection, this to see how the coils used in the tests behaved. Simulations of a PLL were performed to see how good it could handle FSK-demodulation. With the help of a PLL IC and the simulations a working FSK-demodulator could be assembled.

Framtiden för gamla Habo ullspinneri

This report presents an investigation and a new design of Habo Ullspinneris old industrial premises. It is based on the owners visions and wishes, two questionnaires and also considering of the historical value.Habo Ullspinneri was founded in 1882 by Frans August Johansson and was moved to the location it has today, near Hökån in Habo, three years later. The electricity that the machines in the industry needed was extracted from the small river that is placed under the building. In 1960 there was a fire and the result became the end of the industrial activity that had taken place in the building.There is no steady activity in the building at the moment. It is nowadays temporarily used as an agriculture museum and as a store room.

Kategorisering av brandfarliga varor med parametern FIGRA

Rapporten handlar om hur olika brandfarliga varor skall kunna kategoriseras med hjälp av parametern FIGRA. Syftet med arbetet var att kunna undersöka om det gick att använda FIGRA i ett större användningsområde. FIGRA är en förkortning som står för FIre Growth RAte och som belyser olika produkters brandtillväxt. Olika försök har genomförts med standardgods, kartonger med en bestämd kontrollvolym, brandfarliga och icke brandfarliga varor. De brandfarliga varorna var lacknafta, Hammarlack och Karlsons universalklister.

Ombyggnad av lägenheter i ett 1950-tals flerbostadshus till kontorsbyggnad

The report aim to increase awareness of factors that have a major role whenremodelling an apartment building from the 1950s to offices.The thesis can be used for future projects when remodelling apartments to offices.The report can provide ideas and inspirations on how this can be done in aneffective way, ie . A way that does not require rebuilding the supporting structure,but only non bearing walls. The thesis also gives insight on the parts that will needto be supplemented from Boverket?s requirements in terms of accessibility,acoustic and fire requirements.The methods used in this thesis are literature studies, case study and sketch work.In the literature studies, the primary sources were Boverkets byggregler BBR, andArbetsmiljöverkets föreskrift AFS 2009:2 but other literature were also used. Theprimary items were chosen from the literature studies and they were furtheranalysed in the sketch work.

Utvärdering av produktionsrapporterad volym för contorta

The background to this study is that the forest company, Holmen, has found large discrepancies between harvested volume and the measured volume at the industry. Factors like bark features, breakage, double tops, bends and stem damages was noted, and all stems were measured manually. Hypothesis testing with the method "random in pairs" were used to examine whether the harvester measured values significantly differed from the manually measured. The result of a properly calibrated harvester shows in average underestimation of the volume with Skogforsk Pine as a bark function. This means that the harvester isn´t the reason why the volume measured in the industry is lower, the fault is elsewhere. The study also indicates a need for a unique bark function for logepole pine..

Beacons & Internet of Things : A design concept for contect-aware mobile interaction with beacons

Mobile technology is developing quickly and becomming a part of daily life and communication. Bluetooth Low Energy is presented as a new way of mobile interaction. However there are not enough studies in this field on the interaction between mobile devices and the physical world. In order to understand user needs, and to encourage users to interact, we simulated an interaction process through designing and testing a prototype in a specific indoor environment. Prototype effectiveness and main characteristics for future mobile application was evaluated through a qualitative user study with 20 participants who interacted with our prototype..

A/B-testning av Mikrotransaktioner

Mikrotransaktioner är en stor del av dagens internethandel. Det används flitigt på både websidor och i datorspel. Denna rapport tar upp hur ett företag eller en privatperson kan, genom A/B-testning, testa vilken transaktionstyp som är bäst för just deras applikation. Problemet är att det finns många olika transaktionstyper att välja mellan och att det inte finns något bra sätt att få fram vilket som är det bästa för just din applikation. För att försöka hitta den optimala transaktionstypen utnyttjades en testapplikation med olika transaktionstyper.

Therefore, many userrelated activities were implemented in the study: eg. personas, scenarios, sketching and user testing. The project resulted in digital wireframes for an iPhone application using embedded GPS to identify and locate environmentally friendly businesses.

End of line test : En studie av företaget Emotrons linjetestning i produktionen

Emotron is a company specialised in developing, producing and marketing equipment to con-trol, monitor and protect processes and machinery driven by electric motors, with an applica-tion focus. Examples of uses for their products are fans, pumps, lifts and cranes.The project is to look at Emotrons end of line test. The company has seen that at the final test-ing there is a bottleneck that restricts the outflow and prevents an increase in the number of tested products.The purpose of this project is to review how Emotrons end-of-line test works today and if there is a possibility to make the test more efficient in such a way that the quality is not at risk, while increasing the outflow of tested products.The projects first step is to look at and analyse what is causing the bottleneck at the end-of-line. When the analysis is complete, the next step is to review whether there is a possibility to solve the bottleneck and if so in what way can this be done. Emotrons most overall objective of the project is to increase the outflow of the number of tested products without jeopardizing the quality.An analysis has been made on frequency inverters, soft starters and shaft power monitors.

Klinikers Perspektiv på Negativa Effekter av Psykologisk Behandling

Formålet med denne undersøgelse er at undersøge om svenske gymnasieelever føler sig som en del af et nordiskt sprogfællesskab. Dette gennem at undersøge hvilken interaktion eleverne har med de nordiske sprog, hvilke sprog de mener at de forstår, hvad læreplanen siger om Norden og de nordiske sprog, samt at undersøge elevernes holdning til de nordiske sprog. 20 elever opdelt i fire fokusgrupper er blevet interviewet, og læreplanen for grundskolen och gymnasiet, samt læreplanen for faget svensk, er blevet analyseret. Læreplanen opfylder ikke de mål og avtaler som findes omkring den samnordiske sprogpolitik, og resultatet fra samtalerne med fokusgrupperne viser at eleverne først og fremmest kommer i kontakt med de skandinaviske sprog, hvilket viser at fællesskabet primært handler om et skandinaviskt sprogfællesskab. Eleverne opfatter norsk som et smukt og let sprog, hvorimod dansk anses være et grimt og svært sprog.

Teknisk utredning för anslutning av vindkraftverk till elektriskt nät

The city of Kalmar has a desire that their 3D maps of the city should come to a greater use and get residents more involved in Kalmar city. The purpose of this report is to show one way to work with these 3D maps when it comes to presenting information about Kalmar for its residents and tourists in a specific area.  The report also includes information about advantages and disadvantages with the use of 2D and 3D maps in different environments. Various reports and other sources indicate an interest in 3D and a use for this, but even that 2D is still seen as a natural way to read a map.

Delat ansvar för ett enat Sri Lanka: asymmetriska relationers påverkan på fredsprocessen

Since 1983 the people of Sri Lanka has endured an ongoing Civil war, however the intencity has varied over the years. The aim of this theses is to examine what influence the asymmetric relationship between the Sri Lankan goverment and the Liberation Tigers of Tamil Eelam (LTTE) has on the process of negotiating a solution to the civil war. I am also examining whether the asymmetical relationship has changed over time and if these changes have had any effect on the process.To analyze the asymmetries I divide them into material and non-material. I measure the material asymmetries in economic and military resourses, and to measure the non-material I use indicators such as commitment, alternative, controll and legitimacy.The results show that the asymmetrical relations between the parties in Sri Lanka have changed since the 1990s. Factors like 9/11 and the recurrent suicide bombings by the LTTE has had a great influence on the singalese-tamil relationsship.
