Ska jag, ska jag inte?: - En studie av hur intentionen till eget företagande i Norrbotten påverkas av strukturfonderna samt Ikeas etablering i länet

Title: Shall I, shall I not? ? A study of how the intention to engage in entrepreneurial behaviour in Norrbotten is influenced by the financial support from the Structural Funds and the establishment of Ikea in the city of Haparanda. Author: Erica Carlson Tutor: Professor Carin Holmquist/ Docent Monica Lindgren Purpose:The purpose of this thesis is to study what aspects that cause the intention to start a company. Therefore this thesis will look at two different situations, the Structural Funds and the establishment of Ikea in Norrbotten, to try to find out if and how these two situations affect the intention among potential entrepreneurs to engage in entrepreneurial behaviour. Method: A qualitative method is used, since this thesis aims at getting an understanding of a specific phenomena; the intention to entrepreneurial behaviour.

Säkerhet i Wireless Local Area Networks : En studie i säkerhetslösningar utförd på uppdrag av Saab Bofors Dynamics AB.

Saab Bofors Dynamics AB is looking for ways to let the employees work wireless in the future. The security in Wireless Local Area Networks (WLAN) has not been considered very reliable, but new standards and protocols have been developed to enhance the security in WLAN. Since most wireless components soon will have built in support for wireless communication, it is important to have a model to deal with secure wireless communication ready. This is necessary because it is important to protect the company?s information related systems, ensure contingency in the daily work and maintaining the trust of the market and the authorities.

Whispers in the forest : a field study about communication within Vi-agroforestry

The purpose of this study is to explore and understand the social and structural dynamics of an organization working with questions regarding development. The organization in question is Vi-agroforestry, a Swedish based NGO that works around the lake Victoria basin and the focus will be on their office in Rwanda. I have used a qualitative approach and conducted participatory observation as well as semi-structured interviews to gather data. I have emanated from the individuals in the organization by using a theory of microsociological organisationperspecive to understand how the employees create and is created by the existing social structures. (Blomberg, 2003) Even though the office in Rwanda only is a relatively small part of Vi-agroforestry?s operations it is still highly individual and independent from the rest of the organization.

Kylning och torkning av ett högtryckskompressorinlopp

Examensarbetet utfördes på University of Florida vid Department of Mechanical and AerospaceEngineering i deras Energy and Gas Dynamics Systems Laboratory. Laboratoriet forskar på enny gasturbincykel som producerar kraft, värme, kyla och vatten. Cykeln är kallad High PressureRegenerative Turbine Engine (HPRTE) och kombinerat med gasturbincykeln är ettabsorptionskylsystem (VARS). Kylsystemet drivs av spillvärme från avgaser som cirkuleras igasturbinen, den producerade kylan används för att kyla ned högtryckskompressorinloppet.Syftet med det här examensarbetet är att undersöka möjligheten till att kyla ned inloppet tillkompressorn till temperaturer långt under fryspunkten för vattnet i den fuktiga gasen. Om gasenskall kylas till nivåer under fryspunkten måste vattnet föras bort från gasen.

Kvinnlig chef i byggbranchen : faktorer som utgör hinder till avancemang

Background: Studies that have been made in male-dominated organisations shows that only few women have succeeded in advancing to the higher positions in all businesses. Statistics shows that merely 4 % of the managers in all building companies are female. The manager role has earlier always been classified as most suitable for men resulting in barriers for women who strive for management positions. This problem is now very renowned and is called the glass ceiling. To improve the current situation, both the organization's structure and culture, have to be modernized for more women to succeed and get the courage to get into the industry.

Marknadsinriktad Requirements Engineering : kännetecken och centrala aktiviteter

Denna rapport behandlar den marknadsinriktade Requirements Engineering (RE) processen. Allt fler företag väljer idag att implementera standardsystem i sina verksamheter. Den situation som ett standardsystem utvecklas i är annorlunda jämfört med den som ett kundspecifikt system utvecklas i. Detta innebär att den traditionella RE-processen inte är anpassad till dessa nya förhållanden.Syftet med denna rapport är därför att utreda vad som kännetecknar en marknadsinriktad RE-process som stödjer kravhanteringsarbetet vid utvecklingen av ett standardsystem. Rapporten avser även att undersöka hur RE tillämpas av marknadsinriktade systemtillverkare i praktiken.

Jämförelser av olika former av QRA och andra metoder för riskanalys av processindustrier

When performing a QRA you have to consider a number of accident scenarios. How many scenarios you choose often determines the time and resources needed to perform the QRA. The report investigates the possibility that a QRA can be performed using only a few representative scenarios. Further it presents a discussion on how these scenarios should be constructed..

Veingeskolan F - Undersökning av inomhusmiljön samt en konstruktionsmässig utvärdering

Title: Veingeskolan F - Investigation of the indoor environment and a structural analysisMethod: Complete analysis of structural drawings to determine if the school have been constructed correctly. In my teorethical studies of the drawings I must seek out points that may have been damaged from moisture, this contains a full survey of the foundation, walls and ceiling. To strenghten the data collected from the drawings I must visit the school and do field investigations to find out if the school has any problems with the indoor environment.Analysis: I determined that we had some damages on specific places, these damages was caused by leaking roofs, a carpet that was tarnished by strong sunlight in connection with some type of glue and also the ventilation that may have been drawing malodorous air from a shaft in the foundation.Conclusion: I was able to see that the decision to demolish the school was quite drastic, if the county would have done continuous fixups on the construcion when the employes had complained maybe the action to the tear the school down would have been unnecessary. The lack of communication between the two parts lead up to the decision to demolish and build a complete new school..

Framtagning av beräkningshjälpmedel för tvärkraftbelastade förband med förbindare av metall.

The governing set of regulations for structural engineering in Sweden used to be Boverket, BKR. However in the beginning of the 21st century a changeover to new regulations, the Eurocodes, started.The transition was completed in year 2011 when the Eurocodes became the mandatory design work policy for all countries within the European Union. The Eurocodes were implemented to simplify and remove potential barriers to trade that may exist when countries have different design rules.  Since the changeover it has been important for all construction companies to update their knowledge base and their design software.When comparing the two calculation processes they seem similar, but there are a couple of differences worth noting.  With the new regulations, engineers will find that the process when designing joints in timber structures has changed.  What used to be a fairly easy and straight forward calculation procedure has now become tedious and time consuming.The objective of this degree project is to present a product, a dimensioning tool that will help structural engineers when computing lateral load carrying joints in timber structures.The degree project is made up of two parts where the first part is the written report describing the background and theory behind load carrying computations. The second part of the project is the actual dimensioning tool which includes several worksheets in Microsoft Excel. The program treats single and double shear connections of the following:Nail jointsScrew jointsSteel plates (thick and thin types) The user can edit the following parameters:Type of plate/ number of shearsStrength class of timber membersMember and plate sizeType of fastenerDiameter of fastenerLength of fastenerYield moment of fastenerkmod and partial factors for design load carrying capacityThe dimensioning tool was created and developed in collaboration with structural engineers at the company Byggteknik AB.
