The aim of this study is to describe the market for Digital Signage in Sweden and give the reader an increased insight and understanding of the problems that suppliers and buyers of Digital Signage may encounter. The study is abductive and based on a number of qualitative interviews with representatives from potential buyers, an existing user, a supplier and a number of companies with insight into Digital Signage. Our findings show that the companies in this study have not yet reached the stage of being ready to invest in a system for Digital Signage, since the effects on for instance increased sales and potential savings on marketing communication have not yet been clearly proven. Furthermore the study shows that it is important that a supplier has a fundamental understanding of the business model of the buyer. In addition to this, service, support and IT-related issues are of great importance for the potential buyers.

The study's purpose is to describe students' experiences of help and support in mathematics. To investigate this, I adopted the questions: What does it mean, according to the students, to get "help and support in mathematics?" Are there differences in the description of help and support depending on the age of the students? What different kinds of help and support do students feel that they get from their math teachers? What different kinds of help and support would they like to have? The study is based on a qualitative method, group interviews, with three groups of students, one from each stage of primary school in one municipality in Sweden. The students were at the time of the interview in grade 3, 5 and 8. The interviews were analysed from a sociocultural perspective. The results show that what the students primarily consider as the meaning of help and support it is to get individual support from their teacher.

The purpose of this study was to determine if and how the city district of Södra Innerstaden in Malmö, by using the Skärholms model, demand their client to reciprocate. The first problem set was to see how the demand was shown in the social service act from year 1998. From there the motives behind the introduction of the Skärholms model in city district of Södra Innerstaden were researched and also if there were a demand on reciprocity in city district of Södra Innerstaden public administration. The study was conducted in an exploratory way. The method used was to describe the idea behind Skärholms model after examining documents from the public administration.

This study will examine if caregivers, working with people with dementia problems, is in need of support and in what way they see how the support should be designed. Previous research shows that there are many factors in elderly care that affect all of the caregivers. Working with people in this sort if dependence, requires a lot of the caregivers, both mentally and physically. To study if the caregivers consider themselves to be in need of support, and in what way they see how the support should be designed, the study employs a qualitative approach using to types of interviews, one focus group with four assistant nurses, and two individual in-depth interviews with the administrative personnel and one nurse. The results show that the need for support for the caregivers exists. Caregivers working with people with dementia problems, daily face difficulties, some more difficult to handle than others.

In order to facilitate trade between EU members, the European Committee has created regulations that will govern supervision of organic products. Every regulatory agency shall, according to the European Committees regulations, carry out a risk classification of each organic producer they regulate. This study for The National Food Administration compares regulation of Swedish organic products with other countries, and aims to produce a simplified model based on risk that can be the beginning of the risk classification model that Sweden in the current situation don?t have. The thesis is based on three questions: 1) What criteria should we use for assigning organic food producers? 2) How do selected European countries and frontrunners rate organic producers and what can Sweden learn from them? 3) How might a national classification model of organic production look in order to ensure an equivalent level of regulation and prevent competition among private inspection bodies? A review of information gathered from the different countries gave differing results.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

Arbetets struktur kan påverka individens hälsa i både positiv och negativ bemärkelse. Syftet med denna studie var att undersöka den psykosociala arbetsmiljön på Ängdala Skolor. En kvantitativ metod har använts där 50 ut av 55 anställda som under våren 2009 arbetade på Ängdala Skolor har besvarat en validerad enkät. Resultatet analyserades utifrån Karaseks och Theorells krav-kontroll- stöd modell som teoretisk referensram tillsammans med teorier kring socialt stöd och stress på arbetsplatsen. Då populationen var liten har resultatet även till viss del jämförts med en tidigare studie inom samma område, utförd av Region Skåne.

Control of a diesel engine equipped with Variable Geometry Turbine (VGT) and Exhaust Gas Recirculation (EGR) requires a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way.

A degree project has been carried out at Motion Control, Västerås. The degreeproject ?Grafisk Skärm för Inbyggda System? have developed a first prototype of anembedded system with a display, a graphical user interface with touchscreen andpossibilities to communicate with external units.The work initiated with surveys of critical components. A technical specification forthe desired end product was developed. With the technical specification as support,design specifications for hardware and firmware were developed.After the specifications were done, a circuit diagram was developed and a circuitboard was made.

This report describes the work of developing a specification of requirements for Waste Heat Recovery Units. The main part of the paper describes how the work with the specification of requirements has been performed. One specific question to be answered is:What are the customer?s demands in case of properties for the Waste Heat Recovery Units and how is that information collected as an order documentation to suit the business area Oil & Gas?The report begins with a description of the assignment and continues with the aim and background. A theoretical part describes the different areas and methods that have been important during the process.

This thesis explores the changing prerequisites for accountability in terms of Swedish arms export. The study aims to uncover what has happened with the conditions for accountability in Sweden since the responsibility for export control was transferred from the government to the public administration. By investigating how the term ?accountability? has been used in the literature of democratic theory, an abstract ideal model is being created.  Comparing the changed structural arrangements, with each other and the ideal model, it is concluded that the prerequisites for accountability now seems to be in a worse state than they were before..

The purpose of this essay was to examine pupils who leave the Swedish nine-year compulsory school system without reaching the requirements for the Swedish senior high school, and then to compare with those who reach the requirements. I used the following questions to help me reach this purpose:- Where in life are those pupils who reached the requirements for the Swedish senior high school?- Where in life are those pupils who did not reach the requirements for the Swedish senior high school?- What differences are noticeable between these two groups?The method that I used to examine these questions was to send out a questionnaire to the pupils. I also tried to make an explanation to the results with the help of Erwin Goffmanns theories.The result of this essay shows that there is not a big difference between the two groups. They both did equally well after they finished the Swedish nine-year compulsory school..

The purpose of this thesis is to explore the situation for ebooksin Swedish public libraries. The background is anincreasing lending of e-books in public libraries, with anacquisition model formed when e-books were more of anexperiment in a few libraries. The debate has escalated in therecent years and in this thesis I aim to investigate thelibraries? experience with e-books and the current pricemodel. The empirical material comes from interviews witheight head of public libraries in the Västra Götaland region.As theoretical background, I have used Michael Buckland?sfour roles of collections and price models from Lee andBoyle.My results show ambivalence with the price model.

SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational. The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.

This is a qualitative study based on two focus group interviews with a total of six social workers who work with assessing financial aid in two municipalities. The study aims to examine how the social workers experience and handle their ambiguous professional role, on the basis that they are expected to support and control the client. The theoretical framework is the theory about discretion and role theory. The results show that social workers find it difficult to combine these different approaches. Two different groups of strategies that social workers use to manage their professional role have been distinguished, the first is used to combine the different approaches (combination strategies), which are: empathy, to be distinct and to "blame" the organization.
