FAIR data as an enabler for research-led education

As part of my duties as a Norwegian member of EUA’s Open Science Expert Group, I was asked to write an “expert voice” on how to think about FAIR data from an educational perspective. Below is a copy of my short article. How Findable, Accessible, Interoperable and Reusable data enables research-led education FAIR data is an essential component of the open research ecosystem. In this article, Alexander Refsum Jensenius argues that “FAIRification” can also benefit research-based and research-led education, providing opportunities to bring together different university missions....

Which image format should I use?

Many image file formats exist, but which ones are better for what task? Here is a quick overview in my little series of PhD advice blog posts (the previous being tips on dissertation writing and the public PhD defense). Two different image types When choosing a file format for your image, the first thing is to figure out whether you are dealing with a raster image (photos) or a vector image (line illustrations)....

Reflections on Open Innovation

I have been challenged to talk about innovation in the light of Open Research today. This blog post is a write-up of some ideas as I prepare my slides. Looking at my blog, I have only written about innovation once in the past, in connection to a presentation in Brussels about Open Innovation. Then, I highlighted how my fundamental music research led to developing a medical tool. That is an example of “classic” innovation, developing software that solves a problem....

Tips for a public PhD defense

Yesterday, I gave some PhD dissertation advice. Today, I will present some tips for PhD candidates ready for public defense. In Norway, the public defense is a formal event with colleagues, friends, and family present—we typically also stream them on YouTube. The good thing is that when you are ready for the defense, the dissertation has already been accepted. Now it is time to show lecturing skills in the trial lecture and the ability to engage with peers in the disputation....

What should a PhD dissertation look like?

I am supervising several PhD fellows at the moment and have found that I repeat myself in the one-to-one meetings. So I will write blog posts summarizing general advice I give everyone. This post deals with what a PhD dissertation should look like. The classic Ph.D. dissertation Dear PhD fellow (in Norway, PhD fellows are employees, not students): All dissertations are different, yours included. You can write it however you want as long as it is good!...

Making image parts transparent in Python

As part of my year-long StillStanding project, I post an average image of the spherical video recordings on Mastodon daily. Average images The average image is similar to an “open shutter” technique in photography; it overlays all the frames in a video. The result is an image that shows the most prominent parts of the video recording. This is ideal for my StillStanding recordings, because the technique effectively “removes” objects that appear in the recording for a short period of time....

Finding duration and pixel dimensions for a bunch of video files

As part of my #StillStanding project I need to handle a lot of video files on a daily basis. Today, I wanted to check the duration and pixel dimensions of a bunch of files in different folders. As always, I turned to FFmpeg, or more specifically FFprobe, for help. However, figuring out all the details of how to get out the right information is tricky. So I decided to ask ChatGPT for help....

A note is not a tone

I often come across texts that confuse the concepts of notes and tones. Thus this little blog post that I can refer people when explaining the difference. While the terms “note” and “tone” may be used interchangeably in casual conversation, they have distinct meanings from a music theoretical perspective: Note: A note refers to a symbol in musical notation that tells the musician which pitch to play and for how long....

Horizontal and Vertical Averaging is not the same

For my year-long StillStanding project I am generating videograms for all the scenes. Since there is not much motion in these 10-minute recordings, they typically look like stripes. Looking at today’s recording of an unspectacular hotel room in Kongsberg, I noticed how different the horizontal and vertical videogram look: It is fascinating how two averages of the same video recording can be so different. The explanation is simple; they are based on averaging in two different dimensions (horizontal and vertical)....

Sound and Light vs Audio and Video

People often refer to “sound and video” as a concept pair. That is confusing because, in my thinking, “sound” and “video” refer to very different things. In this post, I will explain the difference. Sound and Audio In a previous blog post, I have written about the difference between sound and audio. The short story is that “sound” refers to the physical phenomenon of vibrating molecules, such as sound waves moving through air....
