Konstruktion av 6:e axel på 5-axligportalfräsmaskin

During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..

I tid och rum : en upplevelseanalys av Kärnan

In 2005 Gunhild Eriksdotter published Behind The Facades in which she analyses the ways of approaching historical buildings in archaeology. Eriksdotter emphasizes that the archaeology of buildings is in dire need of renewal videlicet the traditional outlook on buildings as two-dimensional objects need to change. She develops a method of analysing the spatial dimensions in a three-dimensional world. By fusing theories and methods in excavating archaeology and architecture, she is able to give us a new way of approaching buildings. Her method includes the analysing of a buildings material, spatiality and use.

Matematiksvårigheter : Värför och vad kan vi göra

During my practical training period I observed that many of the students have a negative attitude against mathematics. I also observed that these students have a difficulty reaching the goals in the subject. In my opinion there are different factors that can be the reason to why these students experiences mathematics as a difficult subject in school. This is the reason why I wanted to find out which factors that lies behind the difficulties and how the pedagogues work to support these students. It is also significant that every single student get their rights to develop a positive attitude against mathematics and that the pedagogue supports the students in their development.The point with this degree project is to find out, with the help of three pedagogues, which factors that could lead to difficulties in mathematics with students.

För gull och för edela kransar : en identifiering av 22 nyfunna ballader

In February 2005, a collection predominantly containing medieval ballads was found in the library of Växjö. The collectors were mainly George Stephens, originally from Scotland, and Gunnar Olof Hyltén-Cavallius, both active in Småland in the nineteenth century. In connection with an intital inventory of the material, Magnus Gustafsson, ethnomusicologist at Smålands Musikarkiv, marked ballads of uncertain origin with a question mark.The purpose of this essay is to investigate 22 of these marked ballads. To be able to compare them with other material we have developed a method to identify differences. By means of the method both the text and the melody are compared and in addition the differences in terms of quality and quantity are assessed.

Smartphones som undersökningsinstrument

As the number of people owning a smartphone rapidly increases so too does the opportunity for various researchers to exploit this technology. The possibility to recruit people to participate in research studies improves and with it the chance to get more diversified target groups in terms of age, socio-economic status, geographical location, etc.In this essay, I argue that the opportunities smartphones offer in terms of collecting research material is vastly underestimated in several areas, bearing in mind the advantages they present. In order to support my argument, I shall present a case study carried out in the research area of happiness ? an area where the use of smartphones has provided significant opportunities for research.In order to gather the advantages and disadvantages of this method of study from the participants? perspective, I have followed a happiness research study which is a collaboration between Umeå University and The University of Stockholm. I have interviewed the participants of this study in order to assess the advantages and opportunities that smartphones offer in research programs.Overall, the participants? opinion of this research method was generally positive and it was considered to be quite easy to participate in the study and respond to the questions asked.

Teoretisk och experimentell utvärdering av Lättelement AB:s takinfästning

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.

Soldriven kylning i Sverige

This thesis has been performed at the system development company Verendus System AB, together with the home care company Basic Care Unit (BCU).The thesis has consisted of developing a web based informationsystem for BCU in which they can administrate their business. At the time of writing this thesis, BCU was using a windows-application to administrate their activities, which was both costly aswell as resulting in an unnecessary burden. The aim the thesis has thus been to create a platform-independent information system that simplifies and streamlines BCUs work by being user-friendly aswell as imposing some simplifying features.The students has been developing the system by the help of a work method they themselves developed. The method consisted of working in several iterations that each had several milestones. The method resulted in the students knowing easily when each iteration was finished or not.The thesis resulted in a working platform independent prototype.

Röhsska Backstage : är publika arbetsmetoder nästa steg framåt?

The Röhsska museum in Gothenburg has recently launched a new work method, Backstage, that is studied and paralleled to the museums permanent exhibition on Japanese design. In Backstage the museums routine work is executed in full view of the museums visitors in an exhibition area. The study has focused on the museums intentions and the visitors? interpretations in Backstage and Japanese design, as well as the staff?s experience of the work method?s public aspects. The study?s empirical material has been collected through interviews with the museum staff as well as observations and interviews with visitors in both Backstage and Japanese design.

Frysa livsmedelsrester eller kassera dem för biogasproduktion : En studie, ur livscykelperspektiv, av energianvändning och växthusgasutsläpp

Food is widely consumed and in 2011 an average American devoured approximately one ton of food. The production of these goods requires large amounts of energy and contributes to 22-31 % of all greenhouse gas emissions occurring in Europe. More than one third of the produced food is discarded instead of consumed, and food waste make up about 30 % of the waste generated by households. 60 % of this food waste could be avoided if the eatables were handled in a better way.Avoidable food waste arises partly because residues from food are not taken care of, and because the food is not stored in a way that optimise its durability. Residues arises part- ly because of the contradictory and complex demands of everyday life and are, because of our busy lifestyle, difficult to avoid.

Avgränsning av tillrinningsområden till grundvattenmagasin : vilken information ger berggrundens överyta?

Delineation of recharge areas for aquifers is performed in the groundwater mapping process at the Swedish geological survey, SGU. This work is time consuming and performed manually. It is therefore desirable to develop a more general and repeatable method for defining recharge areas for aquifers.The purpose of this study was to investigate two other possible methods to delineate recharge areas for aquifers. The first method was to examine the possibility of using the topography of the bedrock to define the recharge areas for aquifers. To enable this, a method for generating the topography of the bedrock was developed.

E-learning ? en utbildningsmetod och dess nytta

Companies that invest in e-learning have different expectations regarding the outcome of the investment. According to literature and articles it is common that companies see reduction of costs as the primary benefit with e-learning. Therefore we ask ourselves the question if companies have attained the expected benefit of the investment in e-learning and to what extent cost reduction have been a determining factor in the investments? The purpose of the thesis is to examine if companies that invest in e-learning have attained the expected benefits. We also want to examine what the reason for investing in e-learning is and if cost reduction is the primary reason for investing. The study is founded on a qualitative method that is based on a case study in eight companies.

Fotodynamisk terapi vid behandling av skivepitelskarcinom hos katt :

Photodynamic therapy is a relatively new treatment for superficial squamous cell carcinoma in cats. There are no publications indicating that the method is being used in veterinary practice in Sweden at the present time. The method uses the interaction between a photosensitive agent which has been administered to the tumor area, light of a wavelength that can be absorbed by the photosensitiser and the presence of oxygen. In this study photodynamic treatments were performed at the Queen?s Veterinary School Hopital of Cambridge University between 1998 and 2002.

ABC-kalylering i grossistföretag -modelldesign och effekter

Background: A large number of companies works as a link between manufacturers and final users. These companies buys and stores goods to be able to deliver when a need comes up later in the chain. The storage could have a negative effect on profitability and therefore places great demands on the management control systems. ABC as a method has been used with some success in manufacturing for over ten years. In wholesale companies the method is not frequently used.
