SammanfattningExamensarbetet har syftat till att undersöka möjligheten att utrusta Husqvarnas autonomagräsklippare med avståndssensorer. Dessa ska hindra gräsklipparen från att kollidera med hinder i sinomgivning. Gräsklipparen arbetar i en miljö där väder, temperatur, ljusförhållanden och underlagvarierar kraftigt. Detta innebär att kravet på sensorerna är högt.Av de sensorer som undersökts har det visat sig att ultraljud och ?structured light? är de system sombäst skulle kunna uppfylla all dessa krav till ett rimligt pris.I examensarbetet undersöks därför ultraljudssensorer från företaget Maxbotix närmare ochimplementeras i en prototyp.

Background: Investors use companies? credit ratings as a base in their buy and sell decisions. Companies? credit ratings are also used as indicators of safety in the legislation. This means that credit rating agencies have an important role in the society because they communicate the company?s credit rating to investors and other actors in the society.

Diet and lifestyle are closely interrelated and believed to have a significant influence on four major public diseases - cardiovascular disease, cancer, hypertension and obesity, but also affects functional deficiencies like gluten- and lactose intolerance. Health added-value foods are thought to reduce health-related risks or delay the onset of these major diseases. Therefore, interest among scientists, researchers and the public in general has been growing remarkably over the last decade regarding these special foods. The Swedish market seems to be a good target for health added-values food. However, as there are many risks and cost factors involved for companies to enter the market or invest in R&D, it is important to take a step back and analyze the current market situation.

This study focuses on the use of animals in social work from the perspective of social workers. The purpose of this study is to examine social workers? experiences of animal assisted social work and how social workers view the integration of animals in various fields of social work. The research is based on a qualitative method and four semi-structured interviews were conducted with social workers. The theories incorporated in the study are Attachment Theory and Sense of Coherence (SOC).The following results are presented: Social workers are considered to have a more comprehensive understanding of clients compared to their associates who do not hold a degree in Social Work.

The conservation of great apes faces many challenges, one of which is the threat of infectious disease outbreaks. Zoonotic transmission of respiratory diseases from humans to wild great apes has recently been confirmed. Since respiratory disease is one of the major causes of death in both gorillas and chimpanzees, this gives reason for major concern. Little is known about the risks of disease transmission from humans to great apes in natural environments, and there is a need for systematic risk evaluation. Researchers, conservation staff and tourists spend time in very close proximity of wild great apes, sometimes during long time periods, which poses a potential risk of disease spillover. However, the presence of researchers and tourists has been shown to decrease the risk of poaching, making the matter increasingly complex.

The market of today consist of products/services who resemble each other, the differences are small. Their for it?s necessary for the companies to provide added values to the product so it will stand out from the rest of the products and lead to purchase. A well used strategy in the fashion industry is marketing with celebrities, this is considered successful because it brings attention and strengthening to the brand. Because of this, the strategy also branch out to other industries, but the question is if it?s as successful there? There?s also a serious down-side with the strategy and that is that there?s a great risk with using celebrities.

This essay deals with the complexity that I perceive in the collaboration processes between preschool and parents. In the essay I present my interpretation of two self-perceived situations where my experience has been that the cooperation has not worked satisfactorily for either part. As a basis for my conclusions I use different theories and studies within the domain. My own experiences - both from ten years of working in preschool as well as from an eight-year experience of being a parent also comes into use. The purpose of my essay is to investigate how different horizons of understanding can come into collision, and how limitations in our own understanding of the perspectives of others can complicate collaboration between educators and parents.In the first story I discuss a situation where, in my professional role, I go into a conflict with a parent about how we have chosen to implement some changes.

The advantages with product placement in blogs compared to traditional media is shown in earlier empirical findings where consumers found blog posts more credible and informative than a corresponding article in a web paper. It can therefore be argued that the informal structure and personal tonality of the blog reinforces the effects of product placement on brand attitude and intention to buy as the consumer has no persuasion knowledge and does not detect the rewriting of the product as commercial.This paper?s overall aim is to provide concrete implications for how to manage product placement on fashion blogs. The purpose of the essay is therefore to investigate the communicative effects of product placement in fashion blogs as well as to examine if a revelation of commercial interest behind a blog posts about a certain brand effects the consumers? attitude towards the blog and/or brand attitude and intention to buy.

The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.

Just how far is it possible to make learning of new parts for recognition and robot picking autonomous? This thesis initially gives the prerequisites for the steps in learning and calibration that are to be automated. Among these tasks are to select a suitable part model from numerous candidates with the help of a new part segmenter, as well as computing the spatial extent of this part, facilitating robotic collision handling. Other tasks are to analyze the part model in order to highlight correct and suitable edge segments for increasing pattern matching certainty, and to choose appropriate acceptance levels for pattern matching. Furthermore, tasks deal with simplifying camera calibration by analyzing the calibration pattern, as well as compensating for differences in perspective at great depth variations, by calculating the centre of perspective of the image.

Problem and purpose: The authors were interested in studying how large Swedish banks managed liquidity risks when facing the financial crisis of 2008 and whether the implementation of Basel II framework had an impact on the major Swedish banks' capital adequacy. Furthermore, the authors intend to examine how, based on the analysis of the implementation of Basel II, the introduction of Basel III will affect major Swedish banks' liquidity in the future.Method: The essay is written from a quantitative approach and has a deductive perspective. Data was collected from the annual reports of the selected banks to later use relevant theories to analyze the work.Theory: This part of the essay presents relevant theories, a detailed description of the Basel regulatory framework and its requirements, rules for capital adequacy and to relevant key to achieve the Basel regulatory requirements are considered. Furthermore the authors present criticism of the Basel framework and a summary of the key theoretical points to be used for analyzing empirical data.Empirical: In this chapter the data collected from selected banks is presented and processed.Conclusion: The essay authors present the deficiencies and weaknesses that make the Basel II regulatory framework inadequate for the Swedish financial market. Essay authors also present their opinions regarding how the latest form of the Basel regulations could have a more significant influence on the long-term stability of Swedish banks and how this may increase protection against potential liquidity risks..

Branding is becoming increasingly important to companies within the B2B-sector and they put a lot of effort and capital to develop and strengthen their brands. One way of working with brands is through ingredient branding. An ingredient brand is an alliance between two brands where the ingredient brand is applied on a host brand and works as an ingredient on the product. The purpose of ingredient branding is to create competiveness, differentiation and to create quality associations. Ingredient brands can be divided into emotional and functional categories.

Social media provides, as many points out, new possibilities for marketing. Marketing in social media requires a two way communication, rather than the traditional marketing where the communication model is typically sender ? receiver.To create a marketing campaign that is suitable for a two way communication model has its difficulties and risks as well as its opportunities. Opportunities in the sense that the campaign can become a viral, a Word of mouth and create a Buzz, which will reach potential customers, to a bigger quantity for lower costs, with a message that will make a different impact from the types of commercial messages we are used to. Risks in the sense that the message, if not properly aimed and phrased, can be turned overnight into something that humiliates the company and possibly harm its brand.The difficulties in creating such a campaign is to create something that will catch people?s attention, discuss and forward it, while at the same time avoid getting hurt.We aim to describe the internet from a cultural context, and from that point of view explore the types of misunderstandings which often seem to happen when a corporate message is created and sent out in social media, how to avoid putting the image of a company in danger when doing this, and examine if there is ways to know how the message will be received.

Yahtzee is a game based on luck. Yet there are algorithms designed to give an optimal result and succeeds in doing so. This report compares the end result of an optimal algorithm to an algorithm that has been modified for the multiplayer scenario. The modified algorithm tries to win over the optimal algorithm through taking greater risks in its decisions when falling behind in points. The results show that it is not favorable to do so.

The aim of this study is to, from a child?s family relations, describe the usage of terms relating to factors of risk and safety in science and in investigations concerning children in need of protection. It is also of importance in what way the terms are used when the Social Services suggest that measures should be taken, and in which way the children have been heard in the investigations.The issues raised in this study are: (a) How is the current life situation and life quality of the children discussed? (b) The value of factors concerning risks and protection. (c) How is the children?s own descriptions taken in to consideration? (d) Is gender issues considered? (e) How is Lagerberg?s model (Lagerberg, 1998) useful in investigations?The method of analysis is mainly qualitative however it is combined with analysis of literature relevant to the study.
