Modellering och verifikation av hjulupphängning för ett ultralätt elfordon

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Analys och kontroll av hållfasthet på grenställsarm

The thesis was done in collaboration with EAB situated in Smålandsstenar. In the initial discussion faze on doing a thesis with them there was a need to analyze and ensure the strength of an existing product, cantilever racks. This included performing FEM calculations on a model and comparing the results with physical tests.EAB has two models of cantilever racks, a light duty and a heavy duty. Within the heavy duty model series there are five product variants that differ in both size and load capacity. We will be working with the product variant with a load capacity of 1000 kg/arm which is the variant that is in the middle of the series.When we started work on the thesis we did a literature study and couldn?t find any well defined methodology that integrates both product development and computer aided design analysis.

Kalkyler i vården: en översikt och ett praktikfall

This thesis investigates management accounting systems in a Swedish health care environment. Through a qualitative case study of an activity-based cost accounting system that was introduced in 1994 at S:t Görans Sjukhus, a large Stockholm hospital, the following questions are addressed: What benefits can an activity-based cost accounting system offer the Swedish health care providers? What are the potential problems impeding the implementation of such a system? Main findings: an activity-based cost accounting system can improve the understanding of where costs are generated in the production processes. Comparisons between alternative production processes are improved, and the data may serve as a basis for internal pricing measures. Concerning the second question, difficulty in reconciliating the principles of economic control with the culture present in a hospital is identified as the main obstacle to a new management accounting system..

IT och HR varför så krångligt? : En kvalitativ undersökning av ett personaladministrationssystem i ett landsting

IT exist and are needed in larger organisations today, this creates possibilities for new applications. It has become more frequent with IT within HRM which has developed new concepts like e-HRM and HRIS which links IT and HRM together. We have through qualitative content analysis of interviews investigated how IT-tools affect HR-workmanship. The purpose is to create a basis for describing how employees experience their work with HR within a PA-system. The basis of the PA-system will then answer if it contributes or limits the employees and their activities.

Läs: spela!

Abstract Svanvik, Robin (2013). Läs: spela! En jämförande studie av elevers uppfattningar om datorspel, skönlitteratur och lärande. Svanvik, Robin (2013). It Reads: Play! A comparative study of students' beliefs about computer games, fiction reading and learning. This essay is part of a masters degree of pedagogy and investigates the experiences of 10 high-school students concerning playing computer-games-off-the-shelf (COTS) on the one hand, and reading fictional, printed novels on the other. The aim of this study was to learn more about the students' thoughts about playing COTS and reading novels; also, what differences and similarities there might be between these activities. Furthermore, I wanted to know what they thought they might learn from these activities. The theoretical point of departure for the study is twofold: Firstly, a theory of learning as expressed by Illeris (2007) and, secondly, a sociocultural perspective on learning, represented by Säljö (2000, 2005/2010) which includes the educational benifit of both playing COTS, represented by Gee (2007), and reading fiction, represented by Probst (1990) and Langer (1995). The method used in this study is mainly qualitative by nature.

Ideologisk inverkan på SAB:s klassificering av arkeologiavdelning J

The Swedish Library Classification System, known as the SAB-system, can be viewed as a product of the cultural and social norms and values in Sweden during the time in which it was created and subsequently reviewed. The main purpose of this master?s thesis is to examine the archaeology section J in the SAB-system, in order to observe if values and norms within this discipline had any impact on the Swedish Library classification system. Our intention is therefore to verify any correspondence between the choice of topics and hierarchical structure of that section, and the values and norms that ruled the Swedish society during the 20th century at large but with particular emphasis to the academic discipline of Archaeology. At the present, Archaeology is often disputed as a value-free interpretive science.

Soft Softer Sopho : Utformning av ett användbart användargränssnitt för mjukvarutelefoner

Internet is the future and VoIP (Voice over Internet Protocol) is growing in use. Companies are starting to realise the benefits with VoIP. Skype is the number one soft phone on the market but it doesn't satisfy the needs of companies (e.g. transfer calls, redirects calls and so forth) and leaves therefore a gap. The purpose of this master thesis is to provide Objektor AB (thesis initiator) with tips on how to design a usable soft phone that they know is based on relevant human computer interaction research.The method used in the thesis has been iterative development.

Geoenergilager Xylem : Visualisering och lönsamhet

Inom svensk process- och tillverkningsindustri finns det stora mängder spillvärme som sällan kommer till användning. Att hitta olika tekniska lösningar för att effektivt tillvarata denna spillvärme skapar både nytta ur ett hållbart perspektiv samt ur ett ekonomiskt perspektiv för företaget.I denna rapport presenteras en utarbetad beräkningsmodell i Excel. Beräkningsmodellen används för att uppskatta lönsamheten för anläggning av ett högtemperaturlager i berggrunden. Excel-filen ska kunna användas för företag som en första uppskattning om ett borrhålslager är ett alternativ för tillvaratagande av spillvärme. Utformningen av beräkningsmallen utgick från Xylems högtemperaturlager i Emmaboda.Beräkningsmallen testades på Xylems borrhålslager.

Förstudie för kvalitetssäkringav glidande förband vid Hissmoforsvattenkraftsstation : -Specifikt för aggregat G6 och G7

Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..

Underhållskostnader på rundbalspressar :

Costs of maintenance on agriculture machines is something that many farmers has a low knowledge of, it can depend on low interest or that the farmer don?t have enough time. To make it easier for the farmers they can use many computer programs which are available on the market. In this program they can calculate their costs of maintaince on their agriculture machines, for example STANK and JTI machine calculation program. Most of this program is using Svensson (1987) costs model whish was made in Sweden in the middle of 80 decade in a large study.

Utvärdering av energieffektiviseringsåtgärder på Bokelundskolan i Växjö

The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.
