LSD - Hallucination eller flödeseffektiv innovation
Increased competition in the IT industry has sparked a need for developing faster innovation processes with more predictable output. One of the biggest issues when it comes to achieving a faster flow through the innovation process lies in managing its high degree of variation. Proposing a solution to this problem, Lean Software Development (LSD), was developed to provide a framework for how IT companies should organize its software development process to achieve increased speed and quality. This study examines to which extent LSD, as a set of values, principles, methods and tools, can be used to improve flow efficiency in the innovation process. A case study of a multinational IT company was made by conducting ten semi-structured interviews with current employees.
Utvärdering och åtgärdsförslag av energianvändning i kontorsbyggnad
AbstractEmbla 5 is an office building which has done a large improvement. The clients of this building has made an order of WSP and the student Anders Kempe to calculate the use of energy for the building, and after that result proposing further measures which can decrease the energy use of Embla 5.The ground for this report is when calculation of the present energy use of the building is stated. To make that information of a number of parameters such as envelope, the heating system and ventilation has been located and set in to the simulation program IDA ICE which calculate the energy use.To improve the energy use further this project has been concentrated to change the system of ventilation. Today the ventilation system is of the kind CAV (constant air volume) and the air flow is dimensioned for after recommendations from BBR and Arbetsmiljöverket in the office spaces. Consider that Embla 5 is an office building where the people only staying for 8-10 hours/day so was the ide to see how much energy saving if the air flow is reduced the time people not being in the building.

Öppenhet och rymd i det tidiga 2000-talets villaarkitektur
The aim of this Master´s thesis in Art History and Visual Studies is to examine the existence and theexpressions of openness and interior space in the contemporary Swedish architecture of singlefamilyhouses. Research has focused on open-plan housing with open connections between kitchenand living areas, large windows, walls of glass, high ceiling heights and entresol or loft levels, usingtwo case studies and analyses of seven reference objects. Interpretation is based onphenomenological theoretical perspectives.Houses that are more or less transparent permit views from both the inside and the outside. Adiscussion of this potential dilemma is supported by sociological perspectives on identity, life-style,self-presentation, privacy and publicity..
Vetenskaplig publicering i förändring ? En fallstudie av en svensk högskolas implementering av ett öppet digitalt arkiv
Since the beginning of the 21st century the Open Access-movement, which advocates free online distribution of scholarly information, has gained momentum. Authors can provide Open Access to their work in two main ways: by depositing a copy of their research output in an e-print archive and by publishing in Open Access journals. During the past few years, universities and other research institutions throughout the world have established institutional repositories to manage, preserve and provide access to the intellectual output of the university/research institution. The purpose of this master?s thesis is to describe the implementation of an institutional repository at the Swedish University College of Borås.
?Så snart som möjligt? ? En jämförande studie av Open Access-policyer i Skandinavien
Open access (OA) is a publishing model aimed at increasingthe access to academic research results. The object of thisstudy was to contrast nine colleges and four fundingorganizations in Scandinavia with mandatory OA-policies,and to study how they put OA into practice.Inspired by the Open Access Spectrum (OAS), a tool used toappreciate the OA of academic journals, the aim was tograde the policy documents of the colleges using the OASmodel.The study also compares how the colleges implementtheir OA-policies as well as how, and if, the demands fromthe funding organizations are reflected in the policies of thecolleges.The findings show that the OAS is not a tool designed forgreen OA and that all the information needed for the scale tofunction was not found in the policy documents we studied.A selection of the colleges has some demands in theirpolicies, although most of them allow exceptions to be madefrom the mandatory policy. This is shown to be mainly aquestion of academic freedom, and copyright, or rather thanthe degree to which the scientist and the publisher can cometo an agreement on allowing the information to be accessiblethrough OA.The study proposes that the way to change this may be toincrease the demands on OA in the policies, and that the bestsolution might be in stipulations within the employmentcontracts between the individual colleges and scientist..
Utformning & placering av vädringskanaler i ett passivhus, drivet av naturliga krafter
A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.
Sanning med modifikation : En kvalitativ studie om Polisens förtroendearbete på Facebook
The purpose of our study is to see how an organization, and also a administrative authority, communicates by using social media. The organization in this case is the Swedish Police, because of their paradoxical problem with confidentiality versus openness and transparency. The Police has over a hundred Facebook-accounts, where they try to have a open dialogue with their publics without breaking the law of secrecy. Our general purpose of the study is also to see what the pros and cons are of having a own media channel, instead of the traditional media and their often anticipation twists.The result of the study showed that the three different police precincts, which we investigated in our essay, are working in three different ways. The gap may affect their overall reputation and trust gained by their publics.

Elevers förståelse av fotosyntesen och dess koppling till andra organismer
The effects of the deregulation of the electricity market 1996 in Sweden on short-term hydropower regulation are unknown. This report investigates patterns in subdaily regulation in the Ångerman River Basin during the period 1993-2011. Differences in subdaily flows and zero flow events between the periods 1993-1995 and 1996-2011 were studied by analyzing hourly data from 8 regulated and 8 unregulated locations with four subdaily flow variation indices. No correlations between the market deregulation and the regulation intensity in the Ångerman River basin were detected. The number of days natural ranges of variability were exceeded and the magnitude of subdaily variation were significantly higher at regulated locations.
Modellering av ett bränslesystem i Modelica : tillämpat på ett obemannat flygplan
Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.
Opera i Stockholm : Stadsgårdskajen
The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

Sweden AB.
This report will give the reader a description of principles how to measure the
abrasive mass flow in a waterjet cutting system.
The work began with a visit to Water Jet Sweden AB to get a closer look at the
problem. When the analysis of the problem was done the criteria were defined in
the form of demands and desires. The main task of the criteria was to guide the
search for the solution. The work proceeded with an extensive search for
abrasive flow meters along with obtaining information about flow measurement in
general. When the search for abrasive flow meters resulted in nothing all the
efforts were concentrated on finding a principle of measurement that could cope
with the criteria.
Mozilla Open Badges för motivering av lärande på miljöområdet
Idag är det inte bara genom traditionella utbildningar som värdefulla förmågor kan erhållas, utan detta kan även ske genom internet, samt på andra fysiska platser utanför skolan. Dessvärre finns det inte något allmänt accepterat sätt att redovisa denna informella kompetens. För att lösa detta problem har den amerikanska stiftelsen Mozilla Foundation, känd för att ha utvecklat webbläsaren ?Mozilla Firefox?, skapat ?Open Badges?. Open Badges är en typ av e-utmärkelse, dvs.
