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 theoretical background in this essay made clear that the students? knowledge about physics improve, and they express a more positive attitude towards physics as a subject, when they have access to a more laboratory-based learning style. The aim of this study is to research how the placement of the lab relative to the lecture affects the students? experiences and level of knowledge. The study involved students in year eight and was carried out during four weeks.

Each year 225 million pigs are transported within the European Union (EU) for slaughter, fattening and breeding. This results in poor animal welfare due to the fact that animals are exposed to several numbers of stress factors in the vehicle during loading, transit and unloading. Animal welfare can be defined as how well the animal attempts to cope with its environment and during transport there is often severe difficulty for the pigs to cope properly. There is a growing societal concern for animal welfare. This resulted in that the European Union enacted a law called the EU-regulation with certain directives of how to improve the welfare of the animals during transport.

The aim of this study was to examine how newly qualified social workers from Linnaeus University in Kalmar feel that the school has prepared them with the professional skills to meet the demands that exist within social work. Social work education is a generalist training that will result in a professional qualification. With a qualitative approach eight newly qualified social workers were interviewed.We used the sociology of knowledge as an overall theoretical approach. We also used experience- based knowledge as a theoretical approach. One of the study's conclusion was that the graduates had difficulty linking theory to practice.

In this thesis we have tried to answer the question of whether or not the peaceorganizations working in Israel and Palestine have an impact. We have answered the question by analyzing six different organizations; three who work with children and the other three with women issues. The analysis contains a case study of each organization and then a comparison between the two groups. This study is built on theories about; grassroots organizations, women in organizations and intergroup communication. Our conclusions in this thesis show that there are some similarities between the groups as well as there are differences.

Aim: The aim of our study is to analyze and evaluate from a marketing perspective how estate agents can use facebook to strengthen their brand. Method: We have used an inductive study form where we?ve used a quality and a quantity data gathering method. The data has been gathered from an interview with Botkyrkabyggens marketing coordinator and from an internet survey based on a convience selection and a snow ball selection.Theory: SWOT, Brand Equity, Word of Mouth, Customer Relationship ManagementConclusion: Facebook can create and measure "word of mouth" effects, and also create better information management and flow of information compared to traditional marketing for an estate agent. The risks of facebook is the difficulty in educating the staff about the site and the fact that facebook dominates the policies and rules which suddenly can change.

Syftet med undersökningen var att se om lekarbetsmetoden är en effektiv metod för barn med koncentrationssvårigheter och/eller svårigheter med sociala relationer. Jag ville också få svar på om koncentrationsförmågan och förmågan till att etablera fungerande sociala relationer förbättras positivt hos barn/elever genom lekarbete. Jag undersökte pedagogers uppfattningar om och resultaten av lekarbete på några av dessa barn via intervjuer med lekpedagoger och andra pedagoger kring barnet och tog del av utvärderingar och lekschema som lekpedagoger förmedlade. Sammanfattningsvis pekade resultaten av min undersökning på att lekarbete är en effektiv metod för barn med koncentrationssvårigheter och sociala relationssvårigheter och att koncentrationsförmågan och sociala relationer i hög grad förbättrats positivt hos barnet/eleven genom lekarbete..

This project investigates how four teachers work to encourage their pupils? love of reading. The study was conducted with the focus on teachers working in grades 1?3. The teacher?s view of their own role in furthering love of reading is also considered.It is hoped that other teachers will gain inspiration and ideas about how to work to motivate their pupils to read.To ascertain the four teachers? opinions and thoughts I conducted qualitative interviews which I then analysed with the help of sentence concentration.The study shows that the teachers work in similar ways, but what they all have in common is that they further love of reading through methods that include conversation and communication with classmates and teacher.

The aim of this essay is to examine how educated immigrants from former Yugoslavia are experiencing the Swedish labor market and if they feel that there are factors that complicate their ability to establish themselves in the Swedish labor market. We have also examined whether and if so, how their status has changed in connotation with the move to Sweden. The method we have used is a qualitative interview study where we asked questions from a semi-structured interview guide. We chose to make use of both previous research and a number of analytical tools for using these to interpret inequality and discrimination that exist in the Swedish labor against educated immigrants. The results presented four factors that our respondents perceive contribute to difficulty in establishing themselves in the Swedish labor market, these are: contacts, name, validation and trainee post.

Portable IT devices such as laptops, smart phones and computer tablets are becoming ever more ubiquitous. At the same time, the population of the Western world is growing older, with aging bringing about changes with regards to individuals' physical and mental capabilities. These facts raises important questions about how well suited these devices are for use by elderly people. This study focuses on the cognitive aspects of the devices' usability, using the concept of mental models to analyze the users' understanding of a computer tablet. It also draws upon theory of graphical user interfaces in its analyses.

An inflammatory reaction is induced after release of proinflammatory mediators such asinterleukin 1 and 6 and tumour necrosis factor ?. These mediators stimulate the liver tosuppress the syntheses of albumin and endure the syntheses of acute phase protein forinstance C-reactive protein. The aim of this paper was to perform a method validation on animmune turbidimetric assay to quantify C-reactive protein in canine serum at the laboratory atSkara Animals Hospital, Skara, Sweden. The validation involved evaluation of the assaylinearity, precision, stability and recovery.The method was proved to be linear for both TruLab control and Medinor control.

Parenting is increasingly seen as a profession which requires training and support with the purpose of creating improved interaction. A central question appears to be how the concept of interaction is defined. The aim of this study is to examine how training programs, trainers and parents perceive this concept, whether they define it the same way and whether trainers succeed in reaching parents with the message of what it actually is that will improve in the area of interaction. The study uses a phenomenological approach and a qualitative method.The research subject is the parental training program Komet, a manual-based education program for parents. The goal of the program is to offer families training in methods that have strong scientific support in order to reduce conflicts and to improve the relation and interaction between children and parents.One important result of the study is that parents and trainers viewed the concept of interaction from different perspectives.

This study aims to highlight patients´ experiences about and thoughts of side effects fromelectroconvulsive therapy (ECT), a therapeutic method commonly used when having severedepressions. The framing of questions were how the respondents of this study describe theirlife before, during and after ECT-treatment, how the treatment has affected their daily life andhow these experiences may contribute to the awareness of power in professional relations.The study is based on three semi-structured narrative interviews and the main result showedthat, according to my interpretation, ECT as a treatment obliterated memories, quality of lifeand daily structure for all participants. Unfortunately they have all become subjects ofpsychiatric power and have faced considerable difficulty in getting professional recognitionaccording to their severe memory issues. The respondents have lost the ability to relate totheir past which clearly makes them struggle in their present context. A point in commonamong them is that neither of them wanted ECT but, because of the lack of communicationbetween them as patients and the health care in general, they all ended up getting it..
