Create publication ready figures with Matplotlib and TikZ

 September 29, 2019   5 min read
Figures in scientific papers often look less than professional, and sometimes this can even get in the way of understanding the figure. In this blog post we show how to use matplotlib and tikzplotlib to make publication ready figures that look great and can be styled from the document preamble. Beautiful and understandable figures can possibly lead to higher publication acceptance rate, at least I hope so…

He makes intelligent systems even smarter

 October 12, 2018   ~1 min read
In the future, different intelligent systems will need to share data and experiences with each other to become good enough for certain tasks. RISE Industrial PhD student Martin Isaksson’s research is an important step on the way. This area is highly relevant for Ericsson and the development of its 5G but lessons learned along the way might open for many more solutions.

Predicting strongest cell on secondary carrier using primary carrier data

 April 1, 2018   ~1 min read
There is a rapid evolution in telecommunication with denser networks and systems operating on an increasing number of frequency bands. Also in the next generation 5G networks, even further densification is needed to be able to reach the tight requirements, implying more nodes on each carrier. Denser networks and more frequencies makes it challenging to ensure the best possible cell and frequency carrier assignment to a User Equipment (UE), without the UE needing to perform an excessive amount of inter-frequency measurements and reporting. In this paper, we propose a procedure of predicting the strongest cell of a secondary carrier, and the procedure is exemplified in a UE load-balancing use case. The prediction is based on only measurements on the primary carrier cells, avoiding costly inter-frequency measurements. Simulations of a realistic network deployment show that a UE selection based on the proposed secondary carrier prediction is significantly better than a random UE selection for load balancing.

The F Pie Initiative

Sometimes, when I come across a Powerpoint presentation with multiple multi-slice pie charts on a single slide my head hurts and I have to go air-poop for half-an-hour. Now I have decided to take action!

Washing apparatus ready detection (WARD)

Using a PocketLab put on the top of a washing machine, we measure the magnetic field generated by the motor. The magnitude of this vector is used to detect if the motor is on, and when the motor has been off for some time, we say that the cycle is finished.
