Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

Det finns många olika Data Mining-processer som kan tillämpas i ett Data Mining-projekt. Fördelen med att använda en Data Mining-process är att projektet blir strukturerat, processen kan hjälpa till att minska risker som annars kan uppstå och kan medföra att projektmålet förändras. Data Mining-processen som studien har undersökt är generell och studien försöker därmed precisera olika faser av processen, för att anpassas till ett prognostiseringsprojekt.Studien utvärderar den preciserade prognostiseringsprocessen genom att följa och dokumentera ett prognostiseringsprojekt på en tillverkningsindustri. Studien analyserar teoretiskt vilka implikationer tillverkningsindustrin kan möta och även om studiens framtagna process är tillämpningsbar i detta fall. Studien visar att det på en teoretisk nivå går att genomföra studiens preciserade Data Mining-process och visar även vilka risker som kan uppkomma om ett prognostiseringsprojekt inte följer en Data Mining-process..

Vi har skapat en inspirationsbok. En inspirationsbok som egentligen består av två böcker i samma paket. Från ena hållet är det en bok fylld med illustrationer och konstverk som vi anser motiverar och inspirerar. Från det andra hållet är boken fylld av slumpbilder för att hjälpa unga kreatörer, designstuderande och allmänt den yngre formintresserade skaran med att komma bort från hjärnans logiska tänkande under en idéprocess. I denna textsamling kommer ni att kunna läsa om våran process.

The purpose of this Master's thesis is to contribute to a betterunderstanding of children's free time reading book practices by studyingpupils in the school library and their processes of finding and borrowingbooks for themselves to read silently in the classroom, so called free timereading books. The study also includes observations of the staff's role,particularly the school librarian's in supporting pupil's book selection.The empirical material consists of field notes from an etnographic studywhere pupils in 4th grade (aged 10-11) and staff were observed duringthree school library visits. The theoretical framework is inspired byLennart Björneborn's concepts of information practices in libraries:serendipity, integrative library interface, mediation flow and affordancespaces.The study shows that pupils' search for free time reading books in theschool library is relatively routine-based at the same time as it isspontaneous. The process is an interplay with factors such as time,display and interaction in the integrative library interface. In the presenceof adults, finding books becomes an imposed task for the pupils.

När ett IT-företag ska utveckla ett system behöver de en systemutvecklingsmetod. Denna metod används för att de personer som arbetar i ett projekt ska ha en mall för hur de ska utföra sitt arbete. Vad som enligt litteratur verkar vara ett problem idag är att företagen har en metod men använder den inte på ett bra sätt eller inte alls. Detta leder till ostrukturerade projekt utan sammanhang. Om någon slutar i projektet är det svårt för någon ny att sätta sig in i det arbete som gjorts.

 This thesis is based upon the assumption that in Swedish school today it is a wide gap regarding the information flow when pupils are switching school. This was one of the reasons Skolverket published a report clearly stating that this is the case. The purpose of this thesis is to examine and describe how teachers are working in a teacher team at transitions to see and understand what their work may mean individually, in a group and to the school as an organisation. The questions at issue is to see how the teachers cooperate during transitions and how they notice students in need of extra support and students level of knowledge during transitions. The two last questions at issue is first to see how teachers approach parent?s expectations on the school and the teachers, secondly it is to examine what implications their work will have on the school.

Det finns ett behov av personer som klarar av att generera en mängd fräscha, slitstarka och kreativa idéer under press. Denna undersökning omfattar hur mångsidiga Art directors kan arbeta för att framställa och producera material som håller hög standard. Fyra Art directors har intervjuats och givit sin åsikt i ämnet. Utifrån resultaten av intervjuerna och en mängd kreativa tekniker har vi utfört en grundläggande idéprocess. Resultatet av denna process är en konstutställning där vi har skapat ett koncept med fokus på miljö och framtid. - There is a need for people who can generate a large amount of fresh, durable and creative idéas under pressure. This investigation concerns how versatile Art directors work to manufacture and produce material of high standards. Four Art directors have been interviewed and given us their opinion on the subject.

The objective of this study is to understand how people with psychiatric diseases who are enrolled at a psychiatric clinic experience the recovery process and which internal motivations and external factors influence the process. The study is based on interviews with five people who have been enrolled at a psychiatric clinic. Another aim of the study is to understand how the importance of the outpatient care for the personal recovery and the improvement opportunities of the support from the rehabilitation unit that the interviewees see. The study is qualitative and abductive approach was chosen. This means that the study is based on empirical data supported by established theories.

In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).

Motives and reasons behind a decision to change the asylum process in Sweden are the central concern for this thesis. A symbolic political perspective will be applied in order to elucidate the symbolic factors that have influenced the decision process.The Aliens Appeal Board in Sweden will close down at the end of March 2006 and all pending and future cases will henceforth be decided by three administrative courts. This will be done in order to enhance the principles of legal certainty by making the process more transparent and oral. It is an extensive reform, but since very few amendments are made to the applicable substantive law it raises questions about the actual motives behind the change.One reason that seems to have had a major impact on the decision to close down the Aliens Appeal Board is the fact that the board is perceived as a symbol for an inhuman asylum policy. Transferring the process to the courts might ease the attempt to increase the legitimacy of the asylum process.

This is a graduation project in Innovation Management, which seeks to enlighten new theories within the major subject ? the multi?faceted innovation process.The reader is hereby invited to an insight in the more complex perspectives of these types of theories than what has previously been explained in simplified ways.We have conducted research on a company within the cleantech market; Cellkraft AB. The company develops and produces fuel cells amongst other products, which have emerged during their research and development in the fuel cell technology. Cellkraft works in a high?tech frontline market where innovation is key.

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.

Efficiency has become an important objective for many providers of welfare services. Among Swedish schools, both private and public, increased administrative demands seemingly influence operations, and affect teachers negatively through perceived stress. Simultaneously, Swedish students scored an all-time low in the latest PISA survey, and are now performing below the OECD-average in science, mathematics and reading. A central administrative task in the Swedish elementary school is the parent-teacher conference, which is an important activity in supporting the development of the student's knowledge and social skills. Lean is a well-established operations framework, which has proven successful in order to improve process efficiency.

This thesis investigates how web agencys in Stockholm use, value and incoroprate the terms usability, user experience and interaction design in their work process. The purpose of this study is to investigate how creative professionals works with the notions of usability, user experience and interaction design with focus on the end user. Our definition of creative professionals is every employee at a web agency involved in the work process of developing digital artefacts in any capacity. We wanted to investigate how these notions are considered, consciously or unconsciously, during the workprocess. Semi-structured interviews were conducted at three different web agencys with eight different employees.
