Den här rapporten behandlar frågeställningen om hur man kan anpassa systemutvecklingav ett informationssystem enligt livscykelmodellen till att inkludera användbarhetstester. Frågeställningen grundar sig i att god användbarhet inte är ett explicit uttryckt mål i Andersens beskrivning av livscykelmodellen. För att besvara frågeställningen har vi utvecklat och testat ett bokningssystem åt en mindre verksamhet. Utvecklingsarbetet har bedrivits enligt en egen anpassning av livscykelmodellen. Testerna har utförts enligt metoden cooperativ evaluation.

I dagens samhälle tas miljöfrågor allt oftare upp i den allmänna och politiska debatten och ett aktivt miljöarbete är något som i allt högre grad krävs av företag från bland annat myndigheter och miljöorganisationer. Stålindustrin är inget undantag och får därför ofta kritik för att de åtgärder som vidtas inte är tillräckliga.Inom stålindustrin genomför företag ofta investeringar för att minska sin miljöpåverkan trots att avkastning på det investerade kapitalet uteblir. Den institutionella organisationsteorin förklarar dessa handlingar som direkta konsekvenser av likriktning. Det fenomen som studeras i studien är spridningen av miljömedvetenhet eftersom denna anses ligga till grund för investeringarna i miljöåtgärder inom den svenska stålindustrin. Formatet för studien är en fallstudie där den empiriska datainsamlingen skett genom tryckt material och intervjuer.Det kan konstateras att det studerade företagets miljöarbete påverkas i stor utsträckning av andra aktörer inom det organisatoriska fält som företaget tillhör.

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

The purpose of the study is to examine and analyze the relation between the existence of global companies and given support to immigrant- owned companies with large cultural difference from public services. This helps answering the question "Which affect does the existence of local dominating companies have on the establishment of small companies owned by immigrants with large cultural differences?" This has been accomplished through a field study containing twelve interviews with small companies in two different cities and two interviews with the community officials in each city. The research was thereby narrowed to only treat the two cities in Sweden in order to examine the relation between public services support to small immigrant-owned companies and how the immigrants experience the support from them. The analyze was made due to a handful of theories such as the The network theory IP model, Hofstede's 4+1 model and the Product Life Cycle.

The Swedish business cycle is in a strong position at the moment, leading to great results and larger profits. This strong business posture has encouraged companies to increase both their liquidity and revenue. Now there is a dilemma, what actions should or could a respectable business take on these newfound liquid assets.The purpose of this paper is to deliver a clear picture of what options there are for such companies listed on the Swedish stock-market, and how the market wants them to act. To these means we have studied the basic theories linked to this subject and reviewed the cause and effects that motivates them. We have also conducted interviews with the people representing the market through their line of business.In the theory we found several options on what companies in similar situations tend to do.

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

FDI har sedan början på 80-talet växt sig allt större och blivit en av de viktigaste tillgångarna till finansiellt och fysiskt kapital i världen. FDI har enligt många studier en viktig funktion för ett lands ekonomiska utveckling, detta gäller främst för outvecklade länder men också utvecklade länder. Studiens mål var att hitta viktiga faktorer som påverkade FDI inflöde till Sub-Sahara regionen. Den empiriska analysen gjordes med hjälp av en OLS regressionsmodell och hade 42 observationer sammanlagt. Huvudvariabeln var FDI/BNP.

This thesis was performed at Zetterbergs Industri AB. Zetterbergs is designing, building and mounts body systems for trucks, including dumpers and tippers. The assignment for the thesis was to design a door hinge for a spreader gate. The spreader gate is the top of the two tailgates on a dumper or tipper and opens back and outwards when tipping the cargo. The spreader gate controls the mass flow of the material being tipped.

This thesis has been made in cooperation with the forestry machinery producerEco-Log in Söderhamn. The focus of the thesis has been to find a cheaper wayto open the large engine hood of the company?s harvesters. The goal was tofind a solution that could increase the value for the customers by being saferand simpler to use, or, at the least, keep these values at an equal level comparedto the previous solution.In order to make it possible to CE-mark the new solution, it was importantMachinery Directive that came into effect from the beginning of 2010.To begin with, a specification of requirements was set up. Thereafter, anumber of different basic concepts was retrieved and evaluated.

The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.

This study investigates whether the permanent measurement bias (PMB) has changed over time for Swedish companies listed on the Stockholm Stock exchange at least one year during 1996-2000 or 2005-2010. By using the Residual Income Valuation-model the markets' implicit value on PMB is generated through reversed engineering, as values for all variables except PMB are entered such as the market perceived them at the specific valuation date each year. This implicit value is classified into industries and then sorted by their median. Statistical tests are performed to see if there is a difference between the industry median and the accounting-based values on PMB. The difference from period one to period two is also statistically tested for.The study finds that the implicit values on PMB have changed somewhat between the periods; however the fluctuations are not statistically significant.

This article presents a retrospective case study combined with a review of the current literature concerning canine gestational diabetes. A total of 14 cases have been collected from six different clinics in Sweden. There are few previously published reports on canine gestational diabetes. Gestational diabetes is a disease that rarely occurs in pregnant bitches. The condition is due to the rise of progesterone that occurs during the estrus cycle.

Nowdays an efficient production is critical to achieve for companies competing on the market for steel cutting tools. One of such companies is Halmstad based Tooling Support Halmstad AB that manufactures threading-taps, threading-dies and parting off tools, towards a centralized warehouse in Schiedam, Holland. The large amount of different products, approximately 2500 is a big contributor to the problem along with a new order system that creates a demand of low setup times. Previously the company was forwarded orders through quarter based prognoses which enabled planning of the production over a longer time span. Currently the newer order system ZENIT is in use and the company thereby gets their orders weekly.
