Today, my second visit at LiU in short time. Maryam presents her work and fingers crossed for another PhD within an hour or two.

A lot of smörgåstårta at the new ELDA group these days.

Today I visited goto 10 Mjärdevi Science Park and listened to LicEng Johan Melander from SICK IVP. His talk was about CMOS image sensors. Interesting historical overview.

Paper alert:

Christel Sundberg, Mats Persson, J. Jacob Wikner, Mats Danielsson,,Timing resolution in double-sided silicon photon-counting computed tomography detectors, J. Med. Imag. 10(2), 023502 (2023), doi: 10.1117/1.JMI.10.2.023502.

PurposeOur purpose is to investigate the timing resolution in edge-on silicon strip detectors for photon-counting spectral computed tomography. Today, the timing for detection of individual x-rays is not measured, but in the future, timing information can be valuable to accurately reconstruct the in...

hmm, March sunlight makes the reflection of the Loch Ness monster appear on our office wall.

"old" vs "new". why is it so hard to scribble formulae and solving equations on the computer? pen and paper are superior, still.

Of course I can use a symbolic solver for the tedious work and I can use latex to present them neatly.

But manipulate, grasp, and solve... pen is the thing. Unless you have some good tips on a handy tool (no, not wolphram) ...

(a good tip is acheived with the sharpener)

32 years later.

now, the final exams are marked, the last thesis up for presentation, the last courses handed over to the next lucky guy.

Note to self: do not crush the tip of your longest finger if you have scheduled time for wafer probing this week.

And why did I program my password into my muscle memory.

On the plus side though, I can give everyone the middle finger without having to excuse my self.

a bit of python and enjoying the fire makes hacking enjoyable. I might opt for some skill code too today.

ok... so now what? How am I going to install that PDK... reminds me of Leonard Cohen though.
