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.

Välgrundat och nyanserat? : Tolkning och användning av de nya kunskapskraven för Sh 1b i Gy 11
The purpose of this study is to gain a deeper understanding of women's violence against men in intimate relationships, get an idea of ??what forms of expression that this type of violence has and to highlight the men's experiences of violence.There is little scientific research in the field in Sweden. Crime Prevention Council has determined that eight percent of all complaints involving domestic violence in 2010, reported by men over 18 years.

The international studies highlight that the abused men feel ashamed of having been subjected to violence by a female partner.I have been based this essay on two theoretical premises, Per Isdal theory of "violence perspective" and Elaine Bergqvist's definition of the suppression technique.The study was conducted through a qualitative content analysis.
Uppfyller lagstiftningen kaninens beteendebehov?
Rabbits today are used for different reasons. They are often held as pet rabbits but they also can be found at zoos, in laboratories and as a producing animal where their meat, fur or wool are used.
All rabbits in Sweden are protected by the Swedish animal welfare legislation. For rabbits held as pets, in laboratories or at zoos there are more detailed rules or regulations that defines for example how much space the rabbit must have or how the cage should be enriched. For rabbits in the production there is no detailed legislation, which is a problem because their welfare could be hard to secure when the producers do not have any guidelines to follow.
Rabbits are social animals and therefore they should have the company from either one other rabbit, or from the owner.
Jämförelsestudie för tre olika metoder att beräkna genomstansning i betong : Skillnader i genomstansningskapacitet för metoderna i BBK04, EK2 och BHB
Before the European construction standards were introduced in January 2011, it was mainly themethod in BBK04 that was used for calculating punching capacity in concrete structures, and in lesscommon cases the method in BHB. The method of BBK04 is easy to use and have had the samestructure since the first was published in 1979. The Concrete handbook method (BHB) where usuallyonly used when a higher punching capacity was needed and the cross-sectional height where fixed,calculations using this method entails more work, but will in return usually give a higher capacity. Italso allows the use of shear reinforcement to increase the cross-section capacity. The method ofcalculating punching shear in EC2 differs largely from the methods of BBK04 and BHB.

The scientific research consists of two types of methods.

The purpose of the present study is to investigate mindfulness as a New Age phenomenon in the modern western society. Since a religious phenomenon does not exist in a vacuum, but is dependent on its historical and cultural context, my aim is to give a broad depiction of mindfulness and New Age in its wider context, the historical background and the societal implications of common values, themes and concepts that are frequent in the literature, how mindfulness is presented by the authors of popular literature and also how it is presented in science. In order to bring forward a deeper understanding of New Age and mindfulness? role in the modern western society, my intention is to see how the authors of mindfulness claim validity of their doctrines in the discourse. Mindfulness attracts a wide range of perpetrators and is used in many areas in the society today.
