The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.

The title of this thesis is ?The preconditions of the acquisition guarantee- hard to design working political reforms?. The acquisition guarantee (förvärvsgaranti) is a form of credit guarantee issued by the Swedish government to credit institutes that give out housing loans to debtors with poor credit history. The reform hasn´t been used in any substantial extent.The purpose of the study is to investigate whether you could identify any problems with the preconditions that the governmental agency BKN was given to implement the acquisition guarantee, and if so describe which these problems are.Two questions are answered:1.      What preconditions for a working implementation of the guarantee, in the form of rules, objectives and directives was offered by the government in their steering of BKN?2.      How did the structural preconditions for a working implementation of the guarantee look like?By doing a text analysis of central documents I find that the lack of outcome could to some extent be related to weaknesses in how the reform was formulated.

The purpose of this study was to investigate the effects ofparticipation in an integrated intensive stuttering program (IST) on stutteringbehavior, intelligibility and communication attitude, at individual and grouplevels. Five children aged eight to twelve years participated in the study.Stuttering behavior and intelligibility were judged by two independentstudents in speech and language pathology based on a total of eight videorecordings, before, during and after therapy. Communication attitude wasmeasured by the Swedish version of the self-report questionnaireCommunication Attitude Test (CAT-S). At an individual level, the initialstuttering profile and the changes shown during and after the IST varied. Ata group level, a significant decrease in stuttering frequency and asignificantly higher level of intelligibility were found, after as compared tobefore therapy.

The purpose of this essay was to describe how individual members of the self-help group Al-Anon discuss the importance and the influence the group has/have concerning their own lifestyle and self-image. To find answer to this I carried out qualitative interviews with five female members of a local Al-Anon group and later on analyzed the interviews using various concepts based upon the symbolic interactionism. I have mainly used concepts as; role-taking, significant symbols and referencegroup. Through the analysis of the interviews I have seen that the respondents self-image and thereby also their self-esteem has changed since they became a part of their local Al-Anon group. I have also noticed changes in their behaviors in their way of life.

AimThe aim of this essay is to investigate the possibility to exercise climbing within the framework of the physical education in the obligatory school. We investigated how physical education teachers think about exercising climbing in school and how the Swedish Climbing Association is working to reach out to schools.MethodA questionnaire was sent out to 81 schools (Idrottshögskolans partner schools) in suburban Stockholm, which corresponds to 10% of the total amount of schools in that area. A mail interview was also made with a representative for the Swedish Climbing Association who also represented a local climbing association, to collect information about how they worked with schools and youth.ResultsWe have not found anything in the steering documents against exercising climbing during physical education. There are obstacles for exercising climbing during physical education, a wall for climbing is very expensive and the schools have a lack of space for this wall. The results from the questionnaire showed that 76% of all the schools that did not have a wall for climbing wanted to have one.

The purpose of this Master Thesis is to investigate the quality of the library service at the City Library of Uddevalla. In particular this thesis will examine the quality of the library service to people who are disabled. This applies particularly to the service to people with reduced ability to move or to see, which also includes people with infirmities due to old age. We also have investigated how well the library itself is adapted to the disabled. In order to get more information about the library service to people who are disabled, we have studied literature on this subject and the Master Thesis contains a summary of those documents.

In a world of ?formal organizations?, which is constantly exposed for institutionalized super standards and ideas of a what a modern orgnization should be like, the pressure for changes are strong. This is the environment in which Lund University finds itself. Ideas in the beginning of the 21-century is concerning a stronger emfasis on steering, centralisation, re-hieriarchyzation, standardised processes and a new regulation concerning internal control. Through theories of new institutionalism, with conceptions as organizational identity and the expectations of adapting to new ideas, can you track the translation and adaptation that the ideas go through at the university- a decentralised organization where not only freedom has been a concept for the academic parts, but also for the administration.

In recent years, more and more people have started to live double lives. Blogs, Facebook, YouTube and Twitter have created conditions so that we increasingly live virtual lives on the Internet. The gathering of people in this way entails both risks and opportunities for businesses. This study aims to explain how the phenomenon of social media has affected trade and service companies in a marketing and communication perspective. The idea for the essay came to us after we had observed how different behaviors in companies? concerning social media could vary a lot, and how we felt that this affected our personal view of the brands.

This essay will analyse how Asperger?s syndrome and autism spectrum disorder is made in two municipal high schools. I have interviewed school personnel and analysed the schools? policy documents and diagnostic manuals. In this essay AS and ASD are being deconstructed as political and ideological object and I analyse techniques in school, that makes these objects to subjects.The school?s mission is to foster and educate pupils to become desirable citizens and at the same time its aim is to provide an equivalent school.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

The purpose of this study is to investigate the effect of using more promotion material to enhance the in-store communication of sales promotion. In the retail industry today the research regarding the benefits from using various in-store promotion materials is limited, thus this study was carried out to bring clarity to this subject. The study is carried out in two pharmacies and the design of the study was to add more promotion materials to one store, while keeping the other store in its normal condition and then let the stores change conditions after one week e.g. latin-square design. The data collection of this study consists of four different methods: sales data, a questionnaire with 182 customers, an observation study of 300 consumers and an eye-tracking experiment with 41 participants.

This field study examines how politically active radical feminists have reached their position in a group called Sällskapet. The aim of the study is to examine different paths, with the purpose to gain understanding of how to become a politically active radical feminist. Also, processes of social recognition on the field are examined; what is recognized and what taste preferences and behaviors gain a lower value? The different paths to the feminist position have been examined through a qualitative method consisting of a mixture of interviews and participant observations. The question if the position in Sällskapet requires specific experiences has been analyzed through Pierre Bourdieu?s theoretical framework, with a particular emphasis on the concept of habitus, symbolic- and cultural capital.

The ever-growing e-commerce brings many opportunities for society's consumers and businesses. Digitization has strongly contributed to these opportunities and has, among other things, facilitated the search for information and increased the range for the customer. While the opportunities are many, the increased consumption has also brought consequences. The increase in consumption contributes, among other things, to quantities of deliveries and returns as well as increased waste, all of which results in environmental destruction. The issue of sustainability is very topical today and is influenced by almost everything today. In connection with the markets changing, the consumers' behaviors and expectations also change.

Abstract PurposeThis thesis aims to focus on how master students administer scholarly articles after they have found them. The purpose of the study is to detect how and to what extent people administer their articles from a personal information management-perspective (PIM).MethodTo answer the research questions, a web-based questionnaire survey was distributed which was announced to around 2,000 master students from different universities in Sweden. Most of the items in the survey focused on individual storage methods. The respondents were asked to rate the frequency of their different information administration behaviors on a seven level Likert-type-scale. Subsequently, items concerning specific information administration behaviors were posed, followed by questions on the respondent's sociodemographic status.

To create a more accessible environment for disabled people, the Swedish government, in the year of 2001, made the national act of easily eliminated obstacles valid. This national act states that all easily eliminated obstacles in the municipalities, in places and in premises that are public, shall be removed before the end of 2010, no matter if the owner of the place or premise is private or public. According to Boverket, most of the municipalities are not going to be able to reach that goal, why? The aim of this thesis is to compare the two municipalities Kalmar and Karlskrona in their way of implementing this national act, to see where it went wrong and why. By using implementation theories and qualitative empirical data in the form of interwievs with the total of eight people from different administrations in both of the municipalities, the subject was analyzed and discussed.
