Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.

The purpose of this study was to evaluate the effect of bilateral repetitive transcranial magnetic stimulation (rTMS) on language ability in eight participants with aphasia. All participants underwent two periods of treatment and five periods of evaluation. During one treatment period high frequency stimulation was given to the left hemisphere and low frequency stimulation to the right and in one other period placebo stimulation was given. Boston Naming Test and Token Test were used to assess the effects of treatment on naming ability and language comprehension. Results showed that no significant effects were found on group level.

As EU?s authority increased the number of lobbies in Brussels grew. Today there are approximately 15 000 lobbyists in Brussels. EU decisions and EU directives can have a huge impact on companies and organizations. They can however influence these decisions and directives through lobbying.

This study examines the effects of a person's appearence on grading. 80 teachers in Swedish have assessed a text, illustrated with a picture of the supposed author. The pictures were varied by attractiveness, personality in looks, and gender. Furthermore, a text illustrated by a drawing and an unillustrated text were also used in the study. The texts were sent to the teachers by e-mail and assessed on a scale from 1-10 and the Swedish grading scale IG-MVG (Did not pass ? Passed ? Passed with credit - Passed with great credit).

Free play is a term that often common in educational activities. The definition of the term is difficult, but it is about the children themselves decides the scope, content and process in their play. On an after-school, this may mean that it is the children are given the opportunity to freely choose their own activity in the leisure constraints. Free play can be an alternative to other, more controlled activities where adults control framework. The purpose of this study is to investigate the variations in how some children perceive and experience the phenomenon of free play in the after-school and how the children perceive the teacher´s role in the free game.

In Trollhättan municipality approximately 700 school bus stops are in service. To ensure high quality of the performance of school bus operations, with focus on traffic safety, it was decided to conduct a survey of bus stops including assessments of risks.This master thesis aims to identify the factors affecting road safety at bus stops and pedestrian connections, and to conduct an inventory and analysis of selected sites in Trollhättan municipality. The work also aims to show examples of how risk assessment should be performed in future studies. A risk analysis model provided by the Swedish Transport Administration is supplemented and used in a field study. The risk assessment is based on, inter alia, traffic flow, visibility distance, lighting, speed of traffic and the presence of bus shelter.

This study aimed to evaluate the levels of formaldehyde and organic acids that can build up within enclosed spaces. Another goal was to compare two types of paints that can be used as coating barriers within showcases and in turn compare them to the modern, and by many highly recommended, material of Marveseal®. A low volatile waterborne alkyd/acrylate paint and a two component polyurethane paint was compared to Marveseal® in two series of experiments. One series measured the level of formaldehyde, and thus the effectiveness of the three chosen barriers, and the other series measured the level of volatile organic acids, both the acids emitted from the paint itself, and that of the wood. One box in each series were not treated at all and was used as a reference.The fact that different types of materials emit volatile organic compounds have long been known.

We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.

Recently, the IASB and the FASB initiated a joint project to determine which companies that could be defined as investment entities and thus subject to an exception from IFRS 10 Consolidated Financial Statements. The first draft, ED/2011/4 Investment Entities, was published in 2011 and included six criteria that a company must meet in order to be classified as an investment entity. Based on academic theory, the fact that the IASB and the FASB published a joint proposal is interesting for several reasons. Traditional accounting theory tends to distinguish between two different approaches in standard setting: principles- and rules-based. The IASB is considered to have a principles-based approach, while the FASB is considered to have a rules-based approach.

In 1994 a new Forestry Act was accepted in Sweden. One of the aims of the law is to raise consideration forpreservation of biodiversity. Since the new law got accepted and some time has passed, there now lie someinterest in examining whether the law has been effective towards its purpose. Methods suitable for analysishave been examined during this study. The content of this pilot study is based around five parameters whichcan be used to validate the effects of the new law.

AbstractThe purpose of this study has been to provide a deeper understanding of how companies in the travel industry works with social media and electronic Word-of-mouth (eWOM) by analyzing and investigating social media and eWOM and how it effects customers? expectations on the companies service quality. In connection with the purpose we have chosen the following research questions: 1. In which way can companies in the travel industry interact with their customers participation on the Internet through social media. 2.

Diagnosis of adhd, the cause and consequence. A study about the teachers thought about it.The purpose of this study was to examine teachers experience and views about children diagnosed with adhd, and what implication and effects it gives to the pedagogy strategies in the classroom.This is a qualitative study based on the experience of six teachers from primary school. My results have been compiled and compared to special educational research about adhd, from three different perspectives.The results showed that the teachers who have been working as teachers for a longer period, think that the problems of adhd occur primarily due to environmental causes, but then also say that they think the individual causes matters. It is also these teachers that talks very well about medication as a treatment to cure adhd symptoms. The teachers who have worked the shortest time, most of them have some special education from the teacher education.

Today the school is a given place for preventing social problems. The school struggles continuously to live up to the expectations of balancing preventive social work with pedagogy in a satisfactory way.The purpose of this essay is to get a picture of priorities of social work in school. I want to know what it is that affects and controls the principal's decision about what kind of social project they will accept and be a part of.This essay shows that only one of the eleven principals interviewed apply projects based on evidence when they decide about participation in a social project. Instead, the decisions are based on references from other schools. The reason why the principals do not base their judgement on projects which are based on evidence is because they consider the search for results too time consuming.When there is no requirement that a certain part of the social work in a school must be based on evidence, it leads to the children taking part in different social projects which we can not guarantee are good for them.One solution can be to guide the principals through a national social teachingplan, which can assure that social work based on evidence are being applied in the municipality schools as well as the independent schools..

Background and problem discussionThe temporary employment industry has grown extensively during the past two decades since the market was deregulated. Companies today need to be flexible to meet fluctuating demand and economic climate in society which has made the market expand. When using employees not directly employed by the company there is a risk that long term effects appears that the companies have not thought of.Aim of studyTo create a model of what negative aspects companies should consider when making the decision to use temporary employees.Methodological frameworkThe study performed through an abdicative literature study and with an empirical data collection method of a qualitative approach where we interviewed five hiring companies and one temporary agency on the decision of hiring temporary employees.Frame of referenceProblem areas with the use of temporary employments were identified through four perspectives of the organization; the structural, human resource, symbolic and political perspective. The problem areas we address are organizational learning, motivation, risk of eroding human capital, belongingness and conflicts. These will be described and presented together with management control to counter the problems.EmpiricsThe empirics are focused on what aspects the companies of the study considered when making the decision to use temporary employment, what the companies? different reasons for using temporary employment are and what they do to minimize possible negative effects.Analysis and conclusionsCompanies use temporary employees mostly to become more flexible, both numerically and in their competence.

The concept of national security has been a matter for debate during recent years, especially in academic fields. Criticism has surfaced since the end of the cold war, directed towards the traditional perspective's dogmatic focus on armed threats and interstate war. Questions concerning an oncoming paradigm shift have been raised, regarding a widening of the security agenda among national states to also include alternative threats, such as environmental hazards. In this thesis, the focus lies on the effects that climate changes have caused in the Swedish national security agenda during the last 15 years. Swedish policy documents show that there have been some major changes, not only the widening of the security agenda but the entire security domain seems to have changed.
