Användarinvolvering i ett systemutvecklingsprojekt -Är det effektivt?
In most software engineering project, users are only involved in the beginning of the project as a help to design the requirements specification but users can be involved after this phase too, but is it effective to do so? With this report we would like to investigate how effective it is to involve users after the requirements specification has been written and approved. To find out how effective it is to involve the users we try some fast and simple involvement techniques on a quite far gone project. These techniques include ethnographic studies, prototypes and surveys. We also interviewed a couple of people who work with usability and finally delivered a report with our results to them to find out if they found our result relevant.
Persontäthet vid utrymningsberäkningar : Köpcentrums persontätheter
The aim of this study is to evaluate whether the value of occupant load is over or under estimated when the Swedish general value for department stores, 0,5 person/m2, is used for dimensioning shopping centers. The data that was analyzed derives from seven shopping centers and one department store. A conservative method was used to calculate the occupant load factor. The analysis shows that two groups can be discerned: one group that is characterized by a lower occupant load factor that does not exceed 0,3 person/m2, and one group with a higher occupant load factor. Shopping centers with a higher occupant load factor are located centrally in large urban areas.
Risk analysis and a study of risk awareness and risk communication at LEAF Gävle concerning dust explosions
The purpose of this report is to study the risk of dust explosions at the candy manufacturing plant Leaf Sverige in Gävle, Sweden. The risk analysis was conducted with a preliminary hazard analysis, PHA and event trees. The analysis focuses only on the risk posed to employees and material damages at the plant. No third person injuries have been considered. Another purpose of this report is to study risk awareness and risk communication concerning dust explosions.
Självkompakterande betong vid platsgjutning av anläggningskonstruktioner
By using modern methods of casting concrete, cast in place can get more effective and industrialized. A modern method is self compacting concrete. By using this type of concrete, advantages like improved working environment and rationalized construction can be reached. Because the concrete doesn?t need to be vibrated, the amount of staff on site and the noise can be reduced.
Tryggare kan ingen vara? En studie om den danska flexicurity-modellens lämplighet för Sverige
This paper discuss the possibilities to transfer the Danish labour market policy, called flexicurity, to Sweden. There are two main purposes of this essay. The first purpose is to discuss the reasons why the Danish labour market policy could be interesting for Sweden. The second purpose is to investigate which obstacles that might occur during the transfer. For guidance I have used two startingpoints which highlights the Danish flexicurity's pros and cons.

HAVECA-modellen - En metod för att fortlöpande säkra ett internt nätverk mot tredjepart
This thesis will address a problem concerning availability of information
systems at an enterprise within the financial sector and its external
suppliers, so called trusted third party. The information system resides on the
internal network of the enterprise and must be available to both employees of
the enterprise and the trusted third party simultaneously. This contradicts the
company policy which
disallows third parties access to the internal network. The HAVECA-model
introduced in this thesis provides a framework of methods, each solving a sub
problem identified in the model. The identified methods are hardening,
verification, control and assurance, together supplying a method for
continuously securing the internal network against a trusted third party.
Stadsdelsförnyelse i Norra Björksätra, Sandviken
The housing estates in the outskirts of Sandviken, consist of relatively large scale apartment buildings. This report, that is a B.A. thesis at 10 Swedish university points, aims to investigate and describe the opportunities to improve safety and security for inhabitants in Norra Björksätra. The purpose with this report is to make Norra Björksätra to a more attractive place to live in, by changing the negative trends in the area. Since demolition of at least some of the houses could be of current interest in some years; the purpose is also to investigate whether demolition or renewal of the area is the best solution.
Dolt i det öppna
Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.
En studie av zero knowledge-identifikationsprotokoll för smarta kort
Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

RO hantering på ABB, TPE
Arbetet har utförts på ABB i Ludvika med avsikt att förbättra revisionsprocessenför kontroll och skydd. En revision är en ändring på ett godkänt och klarmarkeratobjekt. Då objektet i fråga redan kan vara levererat till kund och man behöver göraen ändring krävs en strukturerad process för att utföra denna ändring. Processen föratt göra detta är i dagsläget komplicerad och kräver en hel del administrativt arbete.Processen använder sig utav ett antal program för lagring och databaser så som,Lotus Notes, HiDraw Studio, och HiDra32.Avdelningen för kontroll och skydd är i fasen att övergå till ett annat elCADsystem, Engineering Base. Detta är också en av anledningarna att man önskar en nyprocess för revisionshantering.Arbetet bestod till en början av inlärning av den dåvarande processen.
Ledningens skådespel: Hur tolkar aktieanalytiker bolagsledningars framföranden?
There has been an increase in the importance and amount of information concerning publicly traded stocks in recent years. When analyzing and valuing stocks finding new ways of collecting information has therefore increased in importance. This thesis aims to explore how meetings with management can impact the stock valuation done by the security analysts. Furthermore the case study examines what kind of information analysts can receive by interpreting management at these meetings. This case study of ten Swedish security analysts show that the analyst?s stock valuation is directly or indirectly affected by the meetings.

Farmers mainly culture rice, and raise pigs, cattle and poultry as well. During two months, a minor field study was performed in Cambodia. The main purpose was to evaluate the impact of contributions done by projects that started in 2005 and were managed by the local organization CelAgrid.
Om solidaritet och ansvarstagande i världen : en diskursanalytisk studie kring internationaliseringen av svensk försvars- och säkerhetspolitik
The world is increasingly coalescing, ecologically, economically and culturally. Many problems can no longer be solved within the own state borders and the limitation of the territorial state is obvious. Jürgen Habermas means that a world domestic politic without a world government is what this progress need. Therefore it is important that national interests become less central and the solidarity between people is given priority in international relations. The focus of this thesis is therefore a critical discourse analysis of the current position of the internationalisation of Swedish security and defence policy.
