Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.

The object of this thesis is to discuss the limits of the hypertext concept. The issue is whether the concept of hypertext necessarily depends on the conditions of the electronic media and www, or if the concept of hypertext more likely is founded on certain textual structures and strategies. In the light of contributions to hypertext theory during the 1990s, this thesis compares different views on hypertext, and concludes with an evaluation. The poem it the authors own translation of the original Danish title det, written in 1969 by the system-poet Inger Christensen, is the object of this case study. The poem is analysed with respect to its structural organisation and literary composition.

The present essay concerns Walter Benjamin´s engagement with the concept of critique in four of his early writings from 1916-1928. It revolves around three main themes, or objects of interest: the critique of language [Sprache], the critique of the work [das Werk] and the critique of history [Geschichte]. The main objective of this study is to show how we can understand Benjamin?s conception of critique and how he develops it in regard to language, the work and history. The essay argues that this is a vital part to understand his philosophy in general as well as his later philosophy of history in particular.

The paper contains comment, clarification and criticism, even constructive criticism, of some theses that have been put forward by Laurence Bonjour in his In Defense of Pure Reason.It presents a concept of experience that deals with the relation between cognizer and object of experience that has a great similarity to that of Bonjour. Through analysis it is shown that the concept of a priori entails that Bonjour has two concepts of a priori, a narrow and a broad one. The narrow one is, in my own words: According to moderate rationalism a proposition p is a priori justified if and only if you apprehend that p must be true in every possible world. This doesn?t mean that Bonjour doesn?t believe in an epistemological, metaphysical and semantic realm.

Abstrakt Sound branding är i dag ett begrepp som är välkänt bland marknadsförare. Fördelarna med en unik och genomarbetad ljudidentitet har dock inte nått fram till många svenska företag och varumärken. Vi ämnar med detta kandidatarbete att utforska ljudets funktion för varumärkesbyggande samt skapa förståelse för vilka faktorer som är avgörande gällande ljuddesignen i reklamsammanhang. Genom tidigare forskning samt produktion av sonic logos och musik, åt olika beställare, har vi försökt besvara frågeställningen: Hur ger man verksamheter och varumärken en ljudidentitet? Abstract Sound branding today, is a well-known concept amongst marketers.

Travelling children is the topic of my work. Children who commute between more than one home. Society is rapidly changing and so is the concept â familyâ . The nuclear family is no longer the most common one. Children are now travelling more frequently than ever.

Detta examensarbete behandlar hur individers mål, ståndpunkter och attityder kring ett föremål kan användas i föremålets design för att individerna lättare skall kunna identifiera sig med föremålet ifråga samt betrakta det som eget och/eller vänligt sinnat. Denna metod för design av föremål testades genom design och modellering av ett stridsfordon, vilket sedan utvärderades i en enkätundersökning tillsammans med ett redan existerande västerländskt stridsfordon. Syftet med undersökningen var att undersöka vilket av stridsfordonen som målgruppen ansåg vara lättast att identifiera sig med/framstod mest som egen.Undersökningen visade att stridsfordonet som designats med tanke på målgruppens  mål, ståndpunkter och attityder också i större utsträckning upplevdes  som vänligt sinnat/egen..

This essay set out to propose a problematic interpretation of the socio-cultural perspective on learning. Its purpose is to show how the socio-cultural perspective on learning defines the concept of knowledge in an incomplete way. The aim becomes then that of giving a more comprehensive description of this concept, and, to this end, to construct a new, broader pedagogic discourse. The investigation starts with a deconstructive analysis of Roger Säljö?s socio-cultural text in order to point out the incompleteness of the concept of knowledge.

Det pågår stora förändringar i världen gällande begreppet design och rapporter har kommit både iSverige och Europa om hur design kan lösa samhällsproblem. Design kan användas som ettverktyg för problemlösning i en arbetsprocess eller som konkurrensfördel i en strategi för attutveckla produkter och tjänster utifrån användarens behov.Forskning finns om hur privata vinstdrivna företag använder design som konkurrensmedel.Syftet med vår studie är att undersöka hur vi med hjälp av design kan skapa en strategi för enorganisation i den offentliga sektorn som kan lösa kommunikationsproblem med fokus påkundtillfredsställelse. Undersökningen syftar till att svara på hur den offentliga sektorn arbetarmed design och hur en designstrategi inom den offentliga sektorn kan se ut, samt om det finnsnågra hinder vid implementering av design.Studien baseras på en kvalitativ metod i form av djupintervjuer, samt en kvantitativenkätundersökning utifrån en fallstudie på Arbetsförmedlingen. Datainsamling av det empiriskamaterialet har gjorts på fallföretaget samt på tre ytterligare tjänsteorienterade organisationer somär finansierade av staten och ett produktorienterat företag. Empirin har analyserats utifrånföretagsekonomiska teorier samt designteorier och den privata sektorn har ställts mot denoffentliga sektorn för att hitta likheter och skillnader dem emellan.Resultatet av studien visar på att design används inom den offentliga sektorn och resultatet visaratt det inte finns några hinder för den offentliga sektorn att jobba med design, men att det iblandkan vara mer svårimplementerat på grund av komplexa organisationer och en målgrupp som ärhela den svenska befolkningen.

This essay focuses on the term usability while conducting a user centred system design. Usabilitymeans to what extent a user can use a product to achieve effectiveness, efficiency and satisfaction.Development using a user centered system design means that knowledge about the end-users andit?s opinions becomes a crucial part of the development process. The question of this essay is if usinguser centred system design will lead to good usability.We used methods from a user centered system design point of view while developing an applicationfor a Swedish bookstore company called Bokia AB. This included user and task analysis following by aclose relationship between the developers and end-users by using sketches and showing themprototypes of the system while collecting feedback.After concluding our case study we determined that using methods from user centered systemdesign could be used as a great tool to further improve the usability and to improve an applicationssuccess chances..

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

The objective with this project was to design a new lifting aid connected to toilet chair.A questionnaire distributed at three homes for aged people indicated that there was an interest in a mechatronic lifting device.Since existing products have limited tilting functionality, the new design was chosen to introduce lifting by motorised tilting of the sitting platform. The mechanical construction was analyzed based on a maximum load caused by a person with weight 160 kg. Two linear actuators were used to control the tilting/lifting of the sit ?place, making standing-up easer.Finally, 28 persons tested the new lifting device and gave their impressions. Many appreciated the safe, stable lifting speed.

This diploma work has been conducted for the consulting company Ramböll inUppsala, Sweden with the purpose to perform a study with the calculation programFEM Design 9.0 made by Strusoft. The aim has been to find out if it is possible to gainadvantage by utilizing more advanced 3D software for design calculations, instead ofthe traditional methods currently used in construction works.The method of approach has been to model an existing warehouse building with theprogram FEM Design, and then compare the results with those attained with FrameAnalysis and hand calculations. These results are then analyzed. An evaluation is maderegarding to what benefits can be achieved using a more advanced 3D-model.The results of the study show that the differences between the methods are not ofany significance with regard to the design of the steel frame. However in morecomplex materials such as reinforced concrete, the differences become more notable.The conclusions drawn by the authors of this study into FEM Design are that theeducation requirements of the program are higher than for simpler programs, whosepurpose are solving predetermined problems.
