The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.

Renewable energy and the charging of electrical vehicles will increase in the future. Therefore the risk of outages is also increasing, partly because renewable energy is intermittent and the production amount can change fast. Charging electrical vehicles is often demanding high effect in short time, which could make faults occur. It takes more advanced technology to short the outage time. Today Övik Energi has high reliability in the power grid, but in order to maintain the reliability, it is time to prevent problems that can occur in the future. This thesis has presented a suggestion for the placement of fault detectors Protrol IPS2, in which a total of four detectors is proposed.

Syftet med studien är att få en förståelse hur förskollärare motiveras till sitt arbete. Vilka faktorer ökar respektive minskar motivation på arbetsplatsen, samt vilken betydelse har arbetets utformande för motivation och arbetstillfredsställelse? Studien utgår ifrån Herzberg (1993) tvåfaktors teori kring motivation samt Hackman och Oldmans The Job Characteristics Model (Robbins & Judge, 2007) som förklarar att arbetets upplägg kan ses som grund för hur motiverad personal är. Studien har genomförts med en kvalitativ ansats utifrån semistrukturerade intervjuer. Sex stycken förskollärare har intervjuats kring upplevelsen huruvida arbetstillfredsställelse och motivation infinner sig.

AbstractThe aim of this literature review was to describe the quality of life in stoma patients after stomasurgery. Different combinations of the keywords ?stoma?, ?Quality of Life?, ?stomasurgery? were used when searching in the databases Medline, Cinahl, Academic Search Elite and PubMed. A total of nineteen articles were used in the result. Fifteen studies had comparing design and four studies had describing design.

Aim is to investigate from a criminological perspective how the safety questionnaire in Älvsborg police district can be improved theoretically and methodologically, in order for the questionnaire to effectively measure criminal victimisation, concern about crime, safety and confidence in the police.1. What should a good questionnaire contain?- Which methodological problems are related to measuring criminal victimisation, concern about crime and confidence in the police?- Which criminological theories are interesting in this context and how can questions be designed from these theories?2. How will the themes now represented in the questionnaire be measured in the best possible way? Are there any reasons to remove, The material consists of questions from the safety questionnaire, the total analysis report and individual reports for the local authorities, as well the results and technical information from Mind Research.

This paper has evaluated a new type of prosthetic foot, X-Balance, which aim was to facilitate the performance on uneven ground for the user. This study have performed gait analyzes with three prosthetic feet, the X-Balance, Flex-Foot and assure Ottobock9192 on flat and uneven surfaces using 3D analysis system QTM (Qualisys Track Manager) and associated force plates. During the project a prototype of a design that can perform a mechanical gait were manufactured. The prototype has then been used to fulfill the purpose and objective of this study which is to make different final sets that demonstrate differences between prosthetic feet. Gait analyses of individuals have also been performed to get an idea of what normal gait is.

Objective: To see if nursing students believe that they have acquired the knowledge that the Higher Education Ordinance demand and if there is any difference between the theory learned at the University and the clinical reality in which students receive their practical training. Method: The method is quantitative and is divided into two parts, one in which the authors describe how the questionnaire was developed and how validity was strengthened. In the second part, the authors describe how the data analysis was made and how reliability of the result was strengthened. Result: The result shows that the students felt that they have achieved most of the objectives of learning demanded by the Higher Education Ordinance. But some objectives are perceived as not at all or only partly achieved.

AbstractTitle: Wikipedia as a source? Is it accepted in the studies of Media and Communications at Uppsala University? (Wikipedia som källa? Är det accepterat vid studier i ämnet medie- och kommunikationsvetenskap vid Uppsala universitet?)Number of pages: 38 (39 including enclosures)Author: Susanna SalomonTutor: Else NygrenCourse: Media and Communication Studies CPeriod: Autumn 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/ Aim: The purpose is to study whether or not the Internet encyclopedia Wikipedia is an accepted source when a student writes a paper in Media and Communications at Uppsala UniversityMaterial/ Method: Qualitative research method based on interviews with teachers and on litterature.Main results: The study shows that there is no common view within the faculty whether or not Wikipedia could be used as a source when writing a paper in Media and Communications. Some accept it, others do not. The results show that the teachers of this subject at Uppsala University have not yet decided upon how to adjust to the new large information bank wich is Wikipedia.Keywords: Wikipedia, Uppsala University, sources, reliability, objectivity, collective intelligence, the Internet.

Cardiac troponin I (cTnI) is considered a specific and a sensitive biomarker of cardiac disease, and due to a high inter-species sequence homology; human cTnI assays can often be used in veterinary medicine. The main aim of this study was to perform an initial evaluation of a human cTnI test, the Meritas Troponin I test, for measurement of equine plasma cTnI, in order to investigate whether the test could be a possible subject for a more comprehensive validation. The hypothesis was that the test could measure equine cTnI, as there is a good homology between equine cTnI and human cTnI. The evaluation included a dilution parallelism, an intra-assay precision study and measurement of plasma cTnI healthy horses. In the dilution parallelism and the intra-assay precision study, equine plasma with previously established high cTnI concentration, according to another cTnI assay, was used. In addition, cTnI concentration was measured in plasma, collected from 19 horses, without signs of disease at physical and ECG examinations. The obtained curve in the dilution parallelism was linear, indicating that the Meritas Troponin I test can be used to measure different concentrations of equine cTnI in plasma.

In today?s IT world where software is constructed in a rapid pace, testing has become a crucial area to master when testing has to be done at a greater speed. To still be able to handle the demands of high quality software, companies have to spend more resources on testing and introduce test automation. By automating test cases the testers can gain time which they can spend on doing more complex testing and thereby increase the quality of the software.In this thesis we have helped Extenda AB, who delivers systems to retail companies, to introduce test automation in one of their customer specific projects. This has been done using their own in-house ?capture/replay? tool ECP (Extenda Cashier Player).We have also derived a process that explains how Extenda can introduce test automation on other customer projects.

SammanfattningGenom denna studie ville jag utforska den agens som uppstår i mötet mellan barnen och den pedagogiska dokumentationen samt hur posthumanistiskt inspirerade analyser av re-visittillfällen kan bidra med förståelse för de yngsta barnens möjlighet till kommunikation och meningsskapande genom den pedagogiska dokumentationen. Jag observerade och filmade re-visittillfällen där en grupp yngre barn möter dokumentation för att få syn på vad som sätts igång i detta möte. Genom att använda en posthumanistisk ansats betraktas inte bara människor, utan också ickemänniskor som agentiska, de gör och genererar förändring (Lenz Taguchi, 2012:12). Tänkande, intention och kommunikation brukar betraktas som mänskliga förehavanden men i ett posthumanistiskt perspektiv betraktas det som fenomen som uppstår i intra-agerande mellan olika agenter. Analyser av filmsekvenserna gjordes utifrån Barads (2007) diffraktionsbegrepp och Lenz Taguchis (2012) begrepp om cirkulära och horisontella rörelser vilka beskriver processerna i användandet av pedagogisk dokumentation.

ABSTRACTStandardized assessment instruments have increasingly come to be used in social work. Although national studies of ASI and DOK's reliability and validity has only been examined to a limited extent. In order to improve knowledge of assessment instruments conditions, relevance and scope, this present literature study highlights the background and the application of the interview methods ASI and DOK, used in swedish abuse and dependent care. In answering the survey questions, a qualitative content analytical method has been used. ASI and DOK are multidimensional interviews which take into account that several areas affecting the client's treatment outcome.
