Företag kan använda sig av olika strategier för underhåll. Det kan vara avhjälpande underhåll som utförs först när ett fel uppkommer eller förebyggande underhåll. Ofta används en kombination av båda. Det förebyggande underhållet kan vara förutbestämt eller tillståndsbaserat. Fördelar med att använda sig av tillståndsbaserat underhåll är exempelvis att utbyte av enheter inte behöver ske i onödan utan först när en observation visar att ett fel är på väg att ske.

Denna rapport bygger på den kommande solcellsfasaden på kvarteret Frodeparken i centrala Uppsala. Projektet genomförs genom ett partneringavtal mellan Skanska Sverige AB och Uppsalahem. Syftet med detta examensarbete var att skapa en underhållsplan samt en investeringskalkyl för projektet. En teknisk bakgrund för solcellsanläggningar har sammanställts för att förstå hur systemet fungerar. Underhållsplanen grundas på fakta från solcellsleverantören och uppgifter från referensobjekt. Det har visat sig att solcellsanläggningar kräver väldigt lite underhåll. För att få en bred syn på investeringen har ett antal simuleringar på investeringskalkylen genomförts.

The paper evaluates two housing proposals with Space syntax as method. The proposals are very different in a topological sense but are in a configural sense almost the same. This effect is because both proposals connect themselves to the existing configural structure of the city in the same way. Neither of them takes advantages of the most integrated streets in the existing structure and use them to concentrate pedestrian and car flows to the streets or points which are intended to be the most urban areas. The knowledge of Space syntax and this evaluation puts focus on the pour understanding among architects and planners of what effect urban design proposals will have..

Site fidelity, the behaviour of animals to return to areas where they have been before is a common trait in many species. The Scandinavian moose is known to show fidelity to its range, but to what extent, is little known. The landscape in Sweden changes in a predictable and unpredictable way and hence gives the opportunity to test the existence of fidelity. I used the kernel Brownian bridge method to estimate the home ranges of individual moose over consecutive years and estimated the overlap at the home range level. I also used Euclidian distance to look on calving site fidelity.

There are few legally protected gardens in Sweden, and those that are protected are mainly from the 17th and 18th centuries. All time periods have the same value and more modern gardens therefore needs to be protected. Evaluating parks is, however, complicated since it do not exist any methods. One environment from the 1960?s that has not been protected is Televerket in Farsta, Stockholm. The facility has been classified as worthy of preservation by Stockholm City Museum and has received the Kasper Salin Prize.

The essay's aim was to see which attitudes county council's and municipality representatives had about themes like: collaboration and competence in the work around double diagnosed persons. Its objective was to zero in on the attitudes of the representatives regarding a coallocated collaboration project in Stockholm. Also, it sought to find out what attitudes the representatives had about the other representatives attitudes concerning the above mentioned themes. A number of attitudes were presented during the qualitative interviews with the representatives, highlighting which attitudes seemed strongest. Then the interviews were analyzed using meaning condensation and then set against the theory of social representations.The analysis showed that before work with the target group starts, there?s a need for synchronization of the different representatives involved in the collaboration project.

Title:The issue of unplanned stoppages caused by failure in medical technology equipment ? A study within the hospital of Kalmar with a focus on manage-ment, security and quality Author:Anna Förster, Ambika Linder, Sandra Nyqvist Tutor:Thomas Karlsson Institution:Linnaeus School of Business and Economics - Linnaeus University Kalmar Date:2011-01-14 Purpose:The purpose of this study was to examine unplanned stoppages caused by medical technology equipment failure in the healthcare operation within the hospital of Kalmar. Our study is based on a number of specifically selected incidents which show the consequences these disruptions cause in management, security and quality within the operation. Our intention was also to examine what role the medical technology department of the hospital plays in the care production operation during these unplanned stoppages. Method:Through a qualitative study we have generated material from a number of interviews with staff working in the hospital of Kalmar.

In today?s society more and more activities are digitalized. This means that everyone has to be able to use information and communication tools (ICT) in order to take part in the digital world, otherwise they will be left out of the digital community. There is a so called digital gap between for instance elderly and young people, where elderly do not know how to use the tools and there for cannot gain access to the digital society. What happens when people, not only grow old, but also have a communication disorder, such as aphasia? How are they included? The purpose of this study is to investigate whether or not surf pads are good tools for bridging the digital gap for people with aphasia, and which activities and situations that encourages people with aphasia to work with the surf pad.

The purpose of this study is to describe the All inclusive concept and to what extent it can be described as sustainable from economic, social and environmental aspects. The empirical study is based mainly on qualitative interviews with four respondents. Two of the informants find the All inclusive concept to be sustainable while the other two are critical to the concept. In the discussion the essay writers argues around the empirical results of the study and how the All inclusive concept possibly could become sustainable. To consider the All Inclusive concept to be sustainable, it is important that the economic, social and environmental aspects are integrated with each other at the destination..

This thesis is a case studie of a newly arrived student placed in a regular class in a P-9 school in a suburb south of Stockholm. The purpose of this study is to investigate how the class teacher for the regular class and the Swedish as a second language teacher are working with this student. The research questions are:What are the basic ideas behind the placement of newly arrived students in regular classes with no previous language skills?How is the language development for the newly arrived student according to the teacher of the selected class?What methods and materials are used by the teacher in her teaching to benefit the newly arrived student?s language development?The purpose of my study has been to investigate the teachers and the headmaster?s perspective on how the integration of newly arrived students into the regular class can be done and the decisions context for the placement of newly arrived students into the regular class. The study is based on interviews with two teachers and the school headmaster.

Evaluations of open Ditch status and function, with an assessment of suitability of a conversion to a two stage ditch as a low maintenance alternative. To illustrate Swedish drainage problems this work focused on two agricultural drainage associations assessed in detail with a new method called MADRAS (Minnesota Agricultural Ditch Reach Assessment for Stability). With the assessment of the MADRAS method estimates were made to conclude the ditches operating problems. This was made through measurements of sediment depths, mass bank failures etc. in order to quantify ditch problems and propose practical actions for improved ditch stability and water quality. The MADRAS surveys were conducted in two main ditches that drains 2900 hectares of land on the northern shores of Mälaren. In the study measurements of the ditch cross-sections were also conducted to compare actual profiles with the original map profiles. The evaluation showed that parts of the studied ditch sections were operatively poor; main reason was mass bank failure, undercut channel banks, sediment aggregations and narrowed ditches. The profile survey shows that a majority of the profiles 80 % has sediment accumulations there remains only 64 % of the original profile from the map.

The objective of this study is to investigate a new pedagogical material called 4DFrame, how it is experienced by informants and how suitable it is in education - in particular mathematics. Socioculturalperspective has a central role in this study when students are given opportunities for linguistic and social interaction during the experiment with the new pedagogical material. The methodology for this study has been visits, interviews, and observations. The study reveals that there are different views on the didactic potential for mathematics of the new teaching material, though no conclusions can be drawn regarding whether this material is more or less suitable in teaching since no research have been found that compares this with other pedagogical materials. Both national and international studies show the need to find alternative and better ways to make mathematic education meaningful.

Under litteraturstudierna fick författarna en uppfattning om att järnvägsbranschen är präglad av en hel del problematik som visat sig i ett flertal brister. Flera större omorganiseringar hade skapat en bransch med otydliga ansvarsgränser och otydliga roller med en mängd utdragna rättsliga tvister mellan beställare och entreprenörer som följd. Stämningen beskrevs som dyster och kompromisser mellan järnvägsaktörer förekom inte i den mån som behövdes, utan aktörerna tänkte mest på sin egen verksamhet. En ändring behövdes.Rapporten är begränsad till tre nyckelaktörer med koppling till järnvägsunderhåll: beställare, entreprenör och trafikutövare. Fokus har lagts på det alltför förekommande avhjälpande underhållet, som visar sig i form av trafikstörningar och trafikstopp.

A method for measuring the total impulse from a multi hole diesel injector, introduced inprevious thesis work, ?Development of a method and a device for measuring the momentumrate of fuel sprays?, by Mikael Lindström, has been further developed and tested. The conceptis to simultaneously deflect all sprays from a multi hole diesel injector by using a bell shapeddeflector. The fuel sprays are deflected straight down from their initial umbrella angle, andthe resulting deflection force is measured in a thin strained section of the load cell. The strainis given by three strain gauges, with quarter-bridge circuitry for each gauge.

How the renovation of the vast Swedish existing building stock with renovation needs will be performed is considered as decisive in order to achieve the target set by the Swedish government of reducing the energy use by 20 percent by 2020. Consequently, the challenge of the building sector consists in reducing the energy use in the existing building stock but at the same time ensuring that the indoor environmental quality is improved and the cultural values are maintained.So far, there have been a few renovation projects which strongly have reduced the energy use and at the same time have taken into account the environmental aspects and the cultural values. The main reasons are that there have been few incentives and a lack of routines in order to steer efficiently a ?sustainable renovation?.The participants in a Nordic project on sustainable renovation thought that it would be a strong advantage to link the concept of sustainable renovation to the Miljöbyggnad certification system. Indeed it is trusted by the Swedish building and construction sectors and can provide sustainability targets in order to steer renovation processes.The objective of the master thesis is to show how the Miljöbyggnad certification system could be integrated in practice in the renovation process of Riksbyggen, an organization which administers housing associations (Bostadsrättsföreningar) and build houses.
