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.
Skönhet kommer från Photoshop - En studie om effekter av retuscherade modeller i reklam
There are widespread discussions about the use of retouched models in media, ranging from bloggers to legal decision-makers. Research shows that there are negative psychological effects on especially females being exposed to idealized, retouched model images. The purpose of this paper is to explore the effects of using retouched models in advertising from a marketing perspective, based on attitudes, perceived quality and purchase intentions.Based on theories about attractiveness, halo-effects and social comparison, an experimental study was done, investigating the different responses on above mentioned parameters to advertisements showing either retouched model images or non-retouched model images. Initially it was also tested if the retouched models were seen as more attractive than the non-retouched models. The results showed almost no differences between the reactions to the advertisements with retouched models compared to the advertisements with non-retouched models, when all respondent groups were analyzed together.

Simulering av hydrauliska dämpare i borrslagverk
This master thesis consists of the creation of shock absorber models for percussive rock drills. A model of the rock was also developed. These models were connected to existing models of the rock drill to create a complete simulation of the rock drilling process.When the models had been created the rock model was evaluated by comparison with measured values from lab tests. The verified rock model was then used to evaluate the shock absorber models.Four new shock absorber concepts have been developed. Three of these have been modelled, while the fourth have only been sketched and described.The evaluation of the models showed the following:? Simulations of the single shock absorber don?t correlate to reality very well.
Evaluation and Comparison of Ecological Models Simulating Nitrogen Processes in Treatment Wetlands,Implemented in Modelica
Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).
Investeringsprocesser i storbanker : en undersökning på tre svenska storbanker
There are no general working processes that can stand for how all the investment process is preceded in the organization of major Swedish banks. It is not a question of investment process but rather a question of, investment processes. How these investment processes operates depends totally on the type and size of the current investment, which unit that is operating the processes and what situation the bank currently finds itself in. There is a written form that describes how the different processes should be operated and which capital budget models that should be used but the usage of these forms can be questioned..
Is less more?
Back in the 1950s Marilyn Monroe and her hourglass shaped body was the aesthetic ideal for how models were to look like. Nowadays, the tide has turned. Research has shown that female models are becoming increasingly taller, narrower and straighter. This trend has occurred despite the fact that both men and women (still) prefer medium sized women with curvy bodies. This essay examines if this trend can be justified from a marketer's perspective.
Etik, öppenhet och relationer : Svenska PR-konsulters syn på sitt arbete
This essay concerns PR-consultants and their view on their work. The purpose was to find out which type of communication they use in contact with the target. By target, we mean the group of people the employer wants to reach with help of the PR-consultant. For example: Jägarförbundet wants to get help from a PR-consultant to influence someone in the government so that Swedish hunters can shoot more wolves, than the target group is the one in the government. We also wanted to find out if the PR-consultants are aware of the image the public have of them and if they are trying to change it into a more positive one, by using more ethics, openness and to have more focus on the relations aspect. PR in the future with new social media (like Internet) was also a subject, where we wanted to know how much they involve social media in their work. Our main questions were:How do PR-consultants relate to openness in communication, ethics and social media?Which one of Grunig?s PR-models is most occuring in the PR-consultants work? We made a qualitative study where we carried out interviews with six PR-consultants.
Högerpopulism i Europa : En studie av tre högerpopulistiska partier och deras egenskaper
The aim of this study is to describe the characteristics of right-wing populist parties in Europe. The three parties included in the study are the Swedish Democrats (SD), the British National Party (BNP) and the National Front (NF) in France. The study includes a definition of right-wing populism based on previous research and from that an ideal type of a right-wing populist party has been created. The material used in the study to verify how well the parties were consistent to the ideal type and what similarities and differences the parties in the study have are the parties? political programs and policies.
Den indiska tigern - En studie av implementeringen av Indiens ekonomiska reformer
The aim of this thesis is to analyze and examine India's economic reforms which the country introduced on the government's own initiative in the early 1990s after decades of practicing isolationism. The analysis entails a thorough systematic examination of possible factors that determined the decision to implement the reforms. These factors are derived from two models developed by scholars within the field of foreign policy.The research is performed through an examination where the possible factors for the reforms have been examined on a three-level basis; system-, state- and individual level. It is a qualitative case study that seeks to explain not only why the Indian government implemented the reforms but also to evaluate the validity of the models to the extent that they stand in accordance with the case of India.The conclusion presented in this thesis is that one model works better for explaining the case of India. The model lie emphasis on structural changes, a crisis and political entrepreneurs committed to a certain type of reforms as a prerequisite for policy change to take place.

Five models were constructed after which they were analysed and compared. The construction of these models were supported by data from the real estate agency Erik Olsson.
A foreign aid dilemma : a study of budget support versus project aid
Foreign aid is a very debated and controversial topic. The most recent studies have focused more on GDP growth and foreign aid correlation, however not much of the debate has focused on what kind of foreign aid should be given. The most common foreign aid is budget support, often a bilateral funds transfer between two countries. This kind of foreign aid can be both conditional and unconditional from the donors? perspective.

Diagnostisering av projekt : En studie med utgångspunkt från SPA-ramverket
The work in project has been around since humans began to hunt in groups, building bridges or building of the Great Wall of China. In 1960- and 70´s, the word project got their value it has today. A project means a work done during a decided time, with decided economy and non-recurring nature (Jansson and Ljung 2004). The projects had a general analytical model. It was used for all projects the organization engaged.
