Project reports

Reports and other presentations I've done for different research projects and courses, sorted by subject/field/area. Having the reports on the WWW, instead of as presentation slides and/or dokuments saves me a lot of time replying to questions and redistributing lost material.

Synchronous Communication

My Licentiate degree (halfway between MSc. and Ph.D) work proposal, with the topic "How to meet the user requirements of room-based videoconferencing". The work has so far resulted in a technical report with the same title that can be found from my publications page.

As a sidetrack of the licentiate work, I developed a Prototype implementation and participated in the standardization of the RTP Payload Format for DV Format Video in the AVT WG of the IETF.

I've done evaluations of different tools for synchronous communication:

Media servers

In 1997 I did a survey over Multimedia Server-related technology for the MERCI project.

I have also built a videoconference session recorder for the SSVLNet and a minimal streaming server for the Internet Multicast module of the Specialization Course (finger course) in Telesystems 1999 using experiences from the Multimedia Server survey.

Asynchronous Communication

I was supervising two Master's Thesis students on Computer support for asynchronous communication in distance learning.
More info on that can be found on the SunTREC at KTH Home Page.

Another result from their work is a web-based groupware tool for asynchronous collaboration called Tobbe

I have done an evaluation of Applix Anyware Java Office by courtesy of Agenda.
The result is in a technical report with the title Evaluation of a Java-based Office-package that can be found from my publications page.

Call handling etc.

Once upon a time I was part of an effort to convert Sun's Montage, a groupware application for quick calls and informal chat between distributed working groups, to Java. At that time there was no real-time support in Java so the project didn't achieve it's goal. However, we had a lot of discussions that finally led George Drapeau to develop some Java Rolodex service compliant with VCard. No idea what happened to it later.

In parallell with the Montage porting, I worked on an idea of a combined information broker, call handling and translation system that I called SPOC (Single Point Of Contact).

Computer Networks

I have done a lot of network-building and -repairing ranging from simple serial connections to machines without display devices through Ethernet wiring, ATM-switching, IP routing, IP multicast routing and a few other things up to analog video and audio.

Distributed Graduate Schools

Here's a little map for you who, like me, easily get lost in the administrative djungle.
