Faktoranalys av EU: s strukturella indikatorer
This paper describes a factor analysis applied at the data of the European Union structural indicators. These are the official indicators for wealth and economic development in the European Union with main use to evaluate the outcomes of the year 2000 Lisbon goals for making the European Union the world?s strongest economy by 2010. The purpose of the data is to serve for comparing and ?learning by doing?-policies, but have, due to size and format, so far been hard to use for a good compare between member countries.
Design av jolleindragare
This project has been about making a design suggestion for a boat accessory that adjuststhe distance between a sail-or motorboat and the dinghy, which is connected by a rope inthe stern. Today this is all done by hand and can lead to problems when it comes tostressful situations such as harbors and narrow passages.A company called Sailsafe came up with the idea and the construction, which they alsohave tested. I found them through an acquaintance at Dacat AB where I did an internshipin the fall of 2010.Using sketching as the primary tool I?ve worked in an almost-real design project with theaim to develop my skills and give the company a relevant design suggestion. Dacat thenhelped me with a 3d model in Alias, which was printed in 3d and painted in thepaintworkshop at school..
E-handel : Vilka faktorer styr konsumentens köp över Internet och då med fokus på hälsokostbranschen?
In today?s IT-community, consumers use the internet in a increasing rate to find information or to purchase products and services. This has led to a growth in the market, but also a greater competition between e-stores and web shops. To separate yourself from the masses has become more important, the question is; what strategy should the IT-salesman use? The meaning of this scientific study is to find and focus on witch the primary factors/aspects are, that controls and is the very foundation for the consumer making a purchase, by using the internet.
Bestämning av ammoniumhalt i Sobackens biogasreaktor
Uppgiften för examensarbetet har varit att göra en bestämning av ammoniumhalten ibiogasslurry med hjälp av jonkromatografi. Resultatet från analysen har sedan jämförtsstatistiskt för att bland annat se repeterbarheten för metoden. Metoden har även jämförts medden spektrofotometriska metoden som finns på Sobacken, så kallad Langemetoden.Ammoniumhalten är en parameter som påverkar biogasbildningen i rötkammaren och det ärdärför viktigt att denna hålls låg.Jonkromatografi är en separtionsmetod som bygger på jonbyteskromatografi. En separationsker i en kolonn innehållande en stationär fas och genom den flödar den mobila fasen ochäven provet. Den stationära fasen och eleuenten har olika laddningar, för katjonkolonnen ärden stationära fasen negativ och den mobila positiv.
Anställningsformers betydelse för häla
The subject of this study was to research whether or not different forms of employment contracts had any effect on self reported health. Whether or not any difference between these forms could be explained through the use of employee health care was also a given point of interest. To achieve this, data from the national Swedish institute of health (FHI) was used, with 6465 of the 12 166 that participated in the study. Logistic regression was the primary statistical method.Initial Chi2-analyzation found no significant difference between the two main employment forms present in Sweden. However, when the variables age, sex and level of education were held constant through logistic regression, a difference of odds at 22% between the two employment forms could be identified.

It´s a project made during the spring 2014 in collaboration with Alutrade AB and ScanBox Thermo Products AB.The assignment is to develop a new transportation trolley for ScanBox. The aim is to complement their range with a product that opens up to new markets. That set new demands for materials and also manufacturing- and assembly methods.
Årstidsdynamik för kvicksilver i ett sövattensediment :
The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment.
The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake.
Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.
Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.
Gymnasiereformer - en jämförelse av politiska argument : En jämförelse mellan gymnasiereformerna 1963 och 2009
The purpose of this paper is to examine witch factors lays behind political decisions when reforming upper secondary school. Three major factors are used: political, economical and structural. These factors become visible by comparing the school reforms 1965 and the coming one in 2009. An analytical scheme is used to find the factors in the primary information. The study is based both political inquiries and on debate articles from newspapers and political papers.The results show that two factors are more visible than the third, and that is the ideological and structural.

Lån utan säkerhet
The Swedish market for unsecured loans has frequently been attacked by media and government officials. Some actors have been accused of exploiting customers and charging inappropriately high interest rates. Despite the public interest very little academic work has been published on the topic. Therefore it is our purpose to investigate why the prices can differ so much between the different actors. Further, we also aim to conduct a market overview as a secondary purpose which will help us in reaching our primary purpose.
Trådlös energiöverföring via elektromagnetisk induktion
This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..

När ett företag ska kommunicera : En explorativ fallstudie kring hur en kravspecifikation tas fram i syfte att välja ett internkommunikationssystem
The importance of internal communication within companies has increased in recent years. However, there are still a number of companies that are not adapted to the modern world and the new modes of communication the Internet provides. This study evaluates the internal communication of a medium sized company by holding semistructured interviews with the employees. The goal of the interviews was to develop a requirement specification. This requirement specification was later used as the basis to analyze possible aids for the internal communication of the company.
