Metoder för trust : Hur praktiker arbetar för att bygga förtroende till knowledge management-system
This thesis examines how knowledge management professionals use trust as a component in the creation of knowledge management systems, and what methods they use for building trust.Adopting a grounded theory approach, interviews with 8 knowledge management professionals active in different industries served as the base for an analysis that identified trust to be the single most important common factor in the data. The concept of trust used by the informants was identified as relating to the knowledge management system itself, rather than other users, employees or groups in an organisation.Building trust, the KM-professionals mainly focused on three methods: simple solutions, system superiority, and implementation security. Using these methods, the KM-professionals seek to ensure system trust by creating opportunities for users to obtain positive experiences of using the system, and thereby generate a foundation for a trust-based relationship between the user and the system..
AUSTERS 1:61 - ett fritidshus på Gotland
A few hundred metres from the beach on Fårö, Gotland, is a small lot with pine trees, green moss and wild fl owers situated, owned by my brother and sister. Eventually they would like tobuild a summerhouse here, in close proximity to their relatives. My project is a proposal for the summerhouse at the site, within the restrictions of 61 m² building area, with focus on interior,exterior and the environment.My proposal is a house close to the surrounding nature, with reference to the the building tratition on the island and with local materials. Orientation to the sun, road and neighbours hasall infl uenced my ideas of this house and the relation between inside and outdoor living, were important in my creative work. The aim was to create a house made for the family and theirholiday lifestyle and allowed consideration for the possibility of a growing family with more children.
Energieffektivisering och solenergi i en universitetsbyggnad : Undervisningshuset och Biblioteket i Uppsala
Akademiska hus is a real estate company that specializes in providing Swedish universities with housing facilities for educational and research purposes. The company strives to reduce its use of energy by 40% between the years 2000 and 2025. The aim of this thesis is to determine which measures can be taken to reduce the need of purchased energy in a building that is used by theSwedishUniversityof Agricultural Sciences inUppsala.In order to determine the results of various changes to the building envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity or heat on site, using solar energy.Results show that economically viable measures include upgrading windows and faucets, adjusting control systems for ventilation and lighting, and installing roof mounted solar panels for power production.
Konstruktion av efterbehandlare
The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.
Den mobila prefabriceringsfabriken : Ett nytt produktionskoncept
This is an investigation of a mobile prefabrication factory´s competitiveness and profitability which also will result in a suggestion for a design of the factory. The mobile prefabrication factory is an idea of a new concept for production which is meant to be used in the manufacture of slab. The main intention with this concept is that by using a fast established prefabrication factory to produce elements near the construction site, thus avoiding transport from the factory to the building site. This means not only an environmental and economic gain, but also that you can avoid risking damage the elements which often occur during transportation. The contractor is owner of the mobile prefabrication factory and can thus avoid long waiting times and cyclicality.
Utfackningsvägg av lättbetongblock i passivhus
AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

Kommunala strategier för kulturhistoriskt intressanta miljöer
The main purpose of this essay was to understand and discuss the problems the Swedishmunicipalities have when missing the profession in cultural preservation area. I have madetwo case studies where competence has been present in one and absent in the other. FurtherI intend to find out what material the Swedish municipalities needs in their work with theconservation of built environment.The first case describes Vallentunas main intersection and the adjustments needed toseparate it from the local rail road. It identifies what the municipality deems importantsuch as sight lines and access to the old church area. The ability to illuminate these itemshad not been possible without the knowledge and early participation of an expert in thefield of cultural resource management.The second case revolves around an old croft in Österåker that was subject for a plannedresidential area.
Utvärdering av VAV i nybyggt kontorshus
VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.
Metod för användning av Geografiska Informations System vid långsiktig vägplanering : en studie genomförd på Sveaskogs marker i Norrbotten
The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas.
The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.
Undersökning av en industrifastighets material och resurshantering enligt miljöcertifieringssystemet LEED
Miljöcertifieringssystemet för byggnader, LEED (Leadership in Energy &
Environmental Design) lanserades 1998 i USA av USGBC (United States Green
Building Council). USGBC är en icke vinstdrivande organisation, vars mål är att
bidra till utökat hållbart byggande. Skanskas första byggnad som certifierades
enligt LEED färdigställdes 2001 i den amerikanska delstaten North Carolina. I
slutet av februari 2009 offentliggjordes det att Skanska skall införa systemet i sin
Nordiska organisation.
Undersökningen som genomförts handlar om ett av LEED New Constructions sex
delområden, Materials & Resources. Materialhanteringen för ett byggprojekt som
Skanska uppfört har analyserats för att avgöra huruvida det skulle kunna erhålla
poäng vid en certifiering enligt LEED.
Konstruktion och design av hjul
The task given to us was to develop an industrial wheel with new thinking in terms of fresh design and construction, with the ability to brake. While the produced wheels of today only own the property of total braking, a wish was made to integrate the ability of directional locking.The time spent working with the project has been filled with multiple sketches of ideas and function analysis.Choices of material and ways of construction have been verified by calculations, tests and prototype building. The goal of this thesis has been to develop a unique caster with well thought-out design that would be adaptable to different areas of applications.The result was a hubless wheel with the ability of directional locking before total braking.A prototype of the wheel has been made to show the design and functions..
