Utvärdering av Transportstyrelsens flygtrafiksmodeller

The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC  will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.

Det osynliga regnbågsbarnet på förskolan : En enkätundersökning om normer, olikheter och särskiljandets betydelse

The purpose of this paper is to see how differences are handled in preschools, with a focus on children with homo- or bisexual parents. By doing this we wanted to see how the conditions for a child with homo- or bisexual parents looks like, in order to have their family conditions mirrored, confirmed and visualised in the preschool.The foundation for the discussion is a questionaire which has been answered by 229 preschool workers from 24 different preschools in the City of Stockholm. The result of the questionaire has been handled in a statistics program. Our analysis is based on the statistical numbers and the written replies to the open questions in the questionaire.As a theoretical starting point we have used Iris Marion Young?s ideas about how our society is coloured by an ideal of similarity that defines liberation as the transcendence of group difference, where the dominant group cannot see how their perspective is just one of several perspectives.

In addition we have looked at myths and connotations shown in the pictures by using a semiotic analysis. The results show that the Swedish tabloids tend to describe the contestants in relation to their performances and personalities.

Gradering av vindkraftslägen i Lerums kommun med hänsyn till infrastruktur och läge

The aim of this master thesis was to find and grade suitable sites for wind turbines in the rural district of Lerum at the reguest of Göteborg Energi. The rural district of Lerum consists of very complicated terrain which was the reason why we picked Lerum.The assignment was achieved by using the software program ArcGIS and its attendant tools. In step 1 an overall analysis was made in order to sort out the least suitable sites. Step 2 consisted of a 3D analysis in ArcScene together with a more precise analysis in ArcMap. As result we found two interesting sites, which met our demands and specific constraints.

Sensory profiling of Swedish white wines and a contextual analysis of Swedish viticulture

The aim of the study is twofold, to generate a sensory profile of Swedish wine today and to investigate the opinion of both wine producers and wine experts on viticulture in Sweden and wine from grapes grown in Sweden, achieved through a contextual analysis comprising a literature study and interviews with wine producers in Sweden and Denmark and wine experts from Sweden and Germany, and a sensory analysis at the company Ipsos. ?Mixed methods? was the chosen research strategy as the semi-structured interviews gave qualitative results and the sensory analysis would give quantitative results displayed as spider charts. There is a lack of studies investigating how the Swedish wine is perceived by consumers and consumers might be unaware that the Swedish wine, established through ?trial and error?, is increasing in quality every season, creating a need to display the sensory profile of Swedish wine to strengthening the perception of Swedish white wine. This study shows that the Swedish white wine today is a wine with a fresh, citrusy and flowery aroma and a fresh, citrusy and green apple taste, however, a sensory analysis cannot show if the attributes are those that are desired by the customer, a consumer test is necessary to conclude that. Trends point towards locally produced products, one reason why Swedish wine has great potential, yet the future needs to be secured through job opportunities and education. Creating an approval system for Swedish wine is suggested as a future improvement, it is a common procedure in most wine regions.

Systemanalys flingtork : Produktionseffektivisering

BillerudKorsnäs is a leading global provider of primary fiber-based packaging materials and on Gruvöns Bruk in Grums, they have chosen to invest millions in the boiler at the facility to increase the total capacity of the factory. This results in the Pulp Flash Dryer at Gruvön being burden more, which makes it important that it is of great reliability and can be run with a high capacity. The reliability of the Pulp Flash Dryer at Gruvön is not as good as one could hope, which leads to reduced availability and production, as well as to increased maintenance costs. There are a number of different reasons for this, but all the casual links are not known.The purpose of this project was to perform a system analysis of the Pulp Flash Dryer to identify bottlenecks and the most critical parts from a capacity- and availability perspective. Appropriate methodology for the system analysis was used and would be used in a structured way to perform the analysis with data from the process and the maintenance system.

Äktenskapet och det förändrade samhället : en kvalitativ studie om den förändrade giftermålsfrekvensen under 1900-talet

In the past, the meaning of marriage has been an agreement between two people to live together and have children in a legitimate manner. The marriage was not just to form a couple; it was also to merge two families together. From the early 1900s until today the allegation of marriage and its influence got a significant change compared to early societies which have aroused my interest to perform this into a research paper. My study is focused on marriage and social changes during the 1900s. Thoughts that arise now is that why there was a remarkable change in the marriage rate during the 1900s and whether there were any social changes had to do something with it.

The research of the essay will be about Solidarity, the Polish trade union that began to rise in the beginning of 1980. In more specific tendencies to the empirical study, it is interesting getting to know about when the free trade union was created with a view to liberate the Polish people from Communism.The essay will be studied as an empirical case study, with a qualitative text analysis. The content will also include how power is allocated to the political, economic and social aspects of the national, and international relations.

According to this, participants in social movements are able to use the most potential and most necessities of resources, just as activists tend to do in reality..

EU - en nyliberal hegemoni? En studie av den nyliberala diskursen i Fördrag om upprättandet av en konstitution för Europa

The fact that we apprehend certain phenomena as more convenient than others generate questions about what constitute and decide what we think of as normal and appropriate. The aim of this thesis is to explore the immense conception of power and authority through a narrower approach that focuses on the EU.With this in mind I examine the penetration of the neo-liberal ideology in the Treaty establishing a Constitution for Europe to see if there are any implications for hegemony. This is achieved through a discourse analysis which is strengthened with empirical cases of EU policies.The result of the discourse analysis of selected parts of the Treaty establishing a Constitution for Europe reveals that there are in fact tendencies which indicate that our society and reality is dominated by a neo-liberal hegemonic discourse. Subsequently the contemporary discourse broadly infiltrates the entire European Union, and therefore also its member states..
