Enstudie om lågtempererat värmesystem i vägg : -Fokus på inomhusklimatet och energianvändning
Today the human being see energy as a matter of course but the resources that is used for extract energy is today not enough for the world demand. Of all the energy that is used in Sweden today approximately 40 % goes to the building stock. This number will most likely increase if not necessary actions will be made on the already existing building stock since new houses constantly are built which will be added up on the already existing energy supply. This takes cause of action on the already existing building stocks, to fulfill the demands of the future use of energy that has been set by the authority. At the same time the thermal conditions cannot be influenced by the necessary changes that must be made.
Produktionseffektivisering av arbetsmoment inom byggsektorn En tidsstudie för standardisering av arbetssätt
Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.
Energieffektivisering i ett verkstadsföretag : En analys av energibesparande åtgärder samt uppvärmnings- och kylsystems driftkostnader och koldioxidutsläpp
The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.
Produktutveckling av koncept för isbanesystem
Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.
Validering av Alberta Context Tool (ACT) för bruk inom svensk kommunal äldrevård : Ett verktyg för implementering av evidensbaserad vård
The aim of this study was to conduct an instrument test of the Canadian questionnaire Alberta Context Tool (ACT) version Long-Term care for Swedish conditions. ACT is designed in order to measure the context in the care environment and different behaviours related to the changes in clinical practice. In total, 159 Licensed Practical Nurses (LPNs) and Registered Nurses (RNs) within municipality care of the elderly were included in the survey. The test included the instrument's reliability and face validity.The reliability test was implemented through calculation of Cronbach´s Alpha, and showed internal consistency for five of the scales of the ACT-instrument with Cronbach´s Alpha values ranging between 0,728 and 0,873. However, three dimensions got lower values (0,558 - 0,683).The analysis was carried out with content analysis and carried out for LPNs and RNs in separate groups.

Competence Portals are software tools that are intended to make it easier for persons that have had no previous contact to find and contact each other. The portals can address areas ranging from finding an expert within an organisation to the marketing of the competence of a region or a research centre to other organisations. The purpose of the thesis is to examine the necessity of Competence Portals in research-intensive organisations. Important characteristics of the information in such portals have been identified and used as a basis for recommendations regarding how Competence Portals could be designed. Furthermore, the thesis focuses on the task of finding a source of knowledge within an organisation.

This thesis has been performed at International Aluminum Casting AB in Eskilstuna,Sweden.International Aluminum Casting is currently working with a number of improvementsin their production in order to achieve their vision of being the leading aluminum foundry in Sweden. As a step in their improvement efforts, focus was directed ondeveloping the company's fixtures for machining.Efforts were focused on two main objectives: to develop a complete proposal on afixture which leads to a more rational use of an assigned part and also form general design advice for development of fixtures in the future.During the work progress, discussions have been made with experts at International Aluminum Casting within the field of fixture design. The objective was to obtain sufficient knowledge about the underlying problems with the current fixture for the part. At this stage of the thesis, a number of essential criteria for fixture design were produced. Information and inspiration were obtained by examining the company?s currently developed fixtures.After gathering the necessary information the process of developing three different fixture concepts started.
Riskkapital : Roller, Involvering och Värdeskapande
In order to drive innovation and growth in a nation is it important to have innovative companies. Many of those innovative companies are smaller companies, which are in need of capital injections for expansion of its operations or to be able to produce a commercial product. In many cases the banks will not lend because they believe there is too great a risk that they will not get their money back. It is in this situation venture capital becomes interesting. Venture capitalists? see the potential the product and/or entrepreneur possesses and are therefore more willing to take the risk in investing in these companies.
Kreativitet : Mål eller medel i gymnasieskolans designämnen
This degree project deals with the concept of creativity and the creative output based on howSwedish upper-secondary design teachers within the Technical Engineering Programexperience this from a student's perspective. The project discusses how the concept creativityis interpreted and how the creative output is regarded by educationalists and professionaldesigners and how this then can be related to literature on the subject and in the steeringdocuments. The purpose of this degree project is to visualize the interviewees' viewpoint oncreativity and the significance of experience, skills, and environment for the creative outputand within the field of design. This in order to, in the pedagogic and didactic situation, enablethe improvement of teaching so that creativity and its output come to show. Moreover, theproject aims to create a ground for discussion of the view of the importance of these skills inthe pedagogic/didactic situation.In order to reach this aim, I have read literature on creativity from several perspectives andcarried out eight qualitative structured interviews: both with three educationalists withoutexperience within the design profession, and with two educationalists who are or have beenactive within the design profession, as well as with three professional designers.
Inventering av tillgängligheten i Bilbergska huset.
Akademiska Hus owns and manages the university facilities in most university towns in Sweden. Bilbergska house in Örebro was built in 2008 by Akademiska Hus, and designed by White Architects.
