The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

Abstract In the contemporary world of information technology you find a multitude of applications and systems covering a broad spectrum of areas of need in different companies. One effect of this multitude of programs is the difficulty to make them exchange information with each other or to collaborate, since they are developed by different programming languages for different platforms, with different standards and different data formats. Our aim with this work is to describe how it is possible to tie these programs together to make them actually communicate with each other in order to exchange information, share their native methods and also to become a part of the overall business processes. In this integration task you will, among other things, find different levels of application integration such as data level, method level, application interface level and user interface level integration. Application integration also involves hardware components, called middleware, that facilitate the physical connection between applications.

Syftet med den här studien var att undersöka hur pedagoger anser att de arbetar med IKT, information- och kommunikations teknik, i förskolan. Syftet var även att undersöka om pedagogerna på något sätt skulle vilja utveckla arbetet med IKT. I denna studie riktas intresset in på surfplattor. Metoden som använts för att få svar på undersökningens frågeställningar är kvalitativa intervjuer, intervjuerna har genomförts med åtta pedagoger från två förskolor. I resultatet av studien blir det synligt att pedagogerna arbetar på olika sätt och att de har olika visioner om hur de vill utveckla arbetet med dessa surfplattor. Resultatet visar att alla medverkande pedagoger i studien använder surfplattan som ett verktyg för att utveckla barnens språk, det ser däremot olika ut bland pedagogerna hur den används till exempel för dokumentation och spel med mera.

The purpose of this study is to exam how two environmental organizations reason about the loss of biodiversity. The research questions are; what is the view in these organizations regarding biodiversity? What are the underlying environmental discourses behind their reasoning, and how do they reason about the risks associated with the loss of biodiversity? As a first part of this thesis a thorough review of existing literature and online resources about the actions of environmental organizations was conducted. Two organizations were interviewed, World Wildlife Fund (WWF) and Naturskyddsforeningen. The questions for the study were analyzed in light of Dryzek´s (1997) reasoning about environmental discourses and using the concept of risk by Beck (1998).

This paper reports a study in how interaction design and graphic design is affected in the process of developing an mobile application to complement the use of an existing webbsite. The paper also ask how developers are affected in this process by the use of designpatterns. The purpous of the report was to see how designpatterns affects the development of mobile applications and how the interaction and graphic design differs between various company webbsites and their related application. A study was conducted by comparing three diffrent webbsites with three related applications to find material for our thesis. Interviews were conducted on three diffrent companys that work professionaly with creating mobile applications.

Information security is an essential part of all information systems; especially in large organizations and companies dealing with classified material. Every large information system has an architecture that includes many parts that together form an Enterprise Architecture. The aim of this thesis is to study how to describe several security functions in an Enterprise Architecture and also how to ensure accountability between requirements and the implementation of the security functions. The description is for stakeholders on a conceptual level rather than a technical level. The study has been carried out by comparing the theoretical framework that has been formed by a study of the literature, and the empirical framework that has been formed by a group discussion and interviews with Information Security Consultants from Combitech AB.

The use of information technology (IT) is exploding. Today, it is in our daily routines to use some kind of information technology. The increase of users increases the number of cyber crimes, ie, crimes that in some way involve IT. As the cyber crimes grow in numbers, the workload for technical investigator increases, these are called digital crime investigators. The thesis is about how police digital crime investigators work and what problems they may encounter during an investigation.

Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.

The aim of the study was to examine both 1) how aware teachers in a specific area are about ICT tools in teaching ; and 2) how likely teachers are to use ICT tools to reverse the trend of unmotivated students and low achievement scores . I will look for answers through the following questions:How extensive is the knowledge of the teachers on digital and social media in education? How have teachers in the past year used various social media in their teaching? In what grade does ICT-supported teaching lead to higher motivation, participation and achievement? Is there a difference between the sexes, different stages (1-3, 4-6, 7-9) and number of years in the profession in knowledge of and openness to the use of ICT in education?The method used is a questionnaire in which a number of respondents have answered a number of questions about ICT tools in teaching. Validity of the study can be said to be high when the survey has measured what it intended to measure, however, I need to be careful in draw full account of the result as the response rate is low with only 39%. In summary, the results show that there is low awareness among respondents about the methods and the digital and social tools I lift in the survey.Mainly the respondents use some of the methods and the digital and social tools in preparation for the lesson.

The aim of this thesis is to research if and in that case how, marketing of Swedish public libraries is used as a possible work method in a time when they are marked by changes in the form of cut backs and technical innovations. With a strive to get an overview by the possible debate I have chosen to do a closer exam of 20 texts published in five of the biggest Swedish library publications during a period of 20 years. My research is based mainly upon Philip Kotler?s marketing theories regarding non-profit organization as well as Eileen Elliot de Saéz interpretations of these to a library context. The first part of the essay therefore consists of an introduction of these, as well as a rendering of their method of work, which shows the width of the conception of marketing.
