Ip-telefoni med Skype som ett alternativ till PSTN för privatanvändare
The project is a practical and theoretical test of IP telephony with Skype in
order to form a base for a comparison between IP-Telephony with Skype and the
Public Switched Telephony Network (PSTN). PSTN is the common standard that most
of us use for telephony today. The objective for the study is to simplify the
choice between PSTN and IP-Telephony for the Swedish private customer user
group.
The project is supposed to answer the following questions.
- How easy is it to start using IP-telephony with Skype?
- How is the quality of IP-telephony compared to PSTN?
- Are all services provided by PSTN available and accessible using the
IP-solution?
- How are the usability and the availability of support with IP telephony?
- Is IP-telephony a cheaper solution and in that case under which circumstances?
Within the project a collection of practical and theoretical tests have been
performed to be able to form an opinion on the IP-solution in the following
areas, installation, function, quality, usability, costs, accessibility and
security.
In order to study usability, a test group of ten persons have been used to
evaluate the usability of the system.

Flygvapnets Transformation : Fallstudie i flygutbildningens omtvistade placering
The transformation among armed forces in Europe is a consequence due to shifted security perspective and the growth of international security actors, such as NATO and the EU. Sweden has played an active role in EU to ensure its influence in forming the security policy for the organisation. Some studies mean it´s because of Sweden?s interest in strengthen EUs roll as a security actor they transformed their own armed forces to be able to take part in international operations. This transformation led to what can be called ?the Swedish defence dismantle? and some studies mean that it has led to the point where Sweden completely lacks the ability to defence themselves.The question is if the ambition to become an active member in these security organisations can explain all the decisions made throughout the Swedish defence-transformation, or if some decisions were made due to other factors?By studying the decision process leading up to the decision to locate the flight education to Malmen in Linköping this study seeks to answer why the decision was made.
Riktlinjer för implementering av ISO 17799
An ongoing concern within the Intellectual Technological world is the issue of security.

Språkstöd i distanslaboratoriet på BTH
To study and laborate at distance, its necessary that the coursematerial is
accessible via internet.
Teaching at more languages than swedish bocomes more common,
why the information of courses needs to exist at several languages.
As teacher, you need a way to publish and edit material of a course. It also
has to be easy for the students to find the information. The distance
laboratory have developed an administrative websystem that handles programme,
courses and students, but misses the possibility for teachers to change content
at the webpages and publish new coursematerial on a way..

Elektronisk signering ? Kommer användaracceptansen att påverkas inom 24-timmars myndigheten?
Utvecklingen av medborgare samt företags användande av Internet har ökat
dramatiskt under de senaste fem åren. Det ökande Internetanvändandet ledde till
att statskontoret 1999 fick i uppdrag av regeringen att ta fram olika förslag
samt underlag som skulle ligga till grund för begreppet 24-timmars myndigheten.
Tjänsten är beräknad att tas tillbruk i Sverige år 2005. 24-timmars myndigheten
kommer tillämpa ett antal olika säkerhetslösningar, därav elektronisk
signering. Denna utredning skall belysa hur stort inflytande säkerhetslösningen
elektronisk signering kommer att ha på användaracceptansen av denna tjänst.
