Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- In this paper I aim to remind a brief projection about the inseparable difference between mental and physical space. This projection intends to thicken the aesthetics of sustainability by rejecting social Darwinism as the normalization of chaos and the irrational by way of evolutionary teleology and technocratic domination. To do so, I describe a mannerist recurrence in cultural production and how I hope it may inform a revitalized movement beyond an age of mass industrialization, beyond claims of Parametricism. I argue that this move can be activated by revising Charles Peirce’s Infinite Community of Inquiry, and Gerald Raunig’s notion of Abstract Machines, as vehicles for anthropocentric cybernetics and contemporary ecology. This is not about metaphorical relations between the visual arts and the hard sciences, but to set forth a topological heuristic, an ongoing inquiry to further categorize aspects between the human and non-human worlds, reflecting through Nietzsche's idea of 'gay science.'

Chemical Studies on Uranium Extraction from Concentrated Phosphoric Acid by Using PC88A and DBBP Mixture.

Tidskriftsartikel (refereegranskat)abstract
- Liquid–liquid extraction of U (VI) from concentrated phosphoric acid by using (2-ethyl hexyl) phosphonic acid, mono (2-ethyl hexyl) ester (PC88A) and di-butyl butyl phosphonate (DBBP) has been investigated. The effect of different factors affecting the extraction process (PC88A concentration, DBBP concentration, shaking time, aqueous/organic phase ratio, phosphoric acid concentration and effect of diluents) have been investigated. The obtained data of temperature on the extraction showed that the enthalpy change is −17.15 kJ mol−1. Uranium was extracted from the strip liquor by using di (2-ethylhexyl) phosphoric acid and tri-octyl phosphine oxide mixture and finally converted to a high purity UO3 product using precipitation with hydrogen peroxide and heat treatment at 365 °C.

Exponential decay of the resonance error in numerical homogenization via parabolic and elliptic cell problems
- 2019

Tidskriftsartikel (refereegranskat)abstract
- This paper presents two new approaches for finding the homogenized coefficients of multiscale elliptic PDEs. Standard approaches for computing the homogenized coefficients suffer from the so-called resonance error, originating from a mismatch between the true and the computational boundary conditions. Our new methods, based on solutions of parabolic and elliptic cell problems, result in an exponential decay of the resonance error.

Pitch-Informed Instrument Assignment using a Deep Convolutional Network with Multiple Kernel Shapes
- 2021
-
Konferensbidrag (refereegranskat)abstract
- This paper proposes a deep convolutional neural network for performing note-level instrument assignment. Given a polyphonic multi-instrumental music signal along with its ground truth or predicted notes, the objective is to assign an instrumental source for each note. This problem is addressed as a pitch-informed classification task where each note is analysed individually. We also propose to utilise several kernel shapes in the convolutional layers in order to facilitate learning of timbre-discriminative feature maps. Experiments on the MusicNet dataset using 7 instrument classes show that our approach is able to achieve an average F-score of 0.904 when the original multi-pitch annotations are used as the pitch information for the system, and that it also excels if the note information is provided using third-party multi-pitch estimation algorithms. We also include ablation studies investigating the effects of the use of multiple kernel shapes and comparing different input representations for the audio and the note-related information.

Architecture as a regular expresion
- 2020
-
Konstnärligt arbete (mjukvara/multimedium)abstract
- A small experiment about formal languages and architectural representation. Besides the generation and translation of a binary string into a raster, and then into an architectural shape, it includes a basic WebGL framework with GLSL and JavaScript code for calculating stencil buffer shadows, based on that by Mikola Lysenko. The code in this repository has been developed as part of Sense Without Meaning, a research project on code and architecture sponsored by Vetenskapsrådet, the Swedish Research Institute. You can see the code running here.

Arktiska spår : Natur och kultur i rörelse
- 2020
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- Arktiska spår: Natur och kultur är en mångvetenskaplig antologi om förändringsprocesser i världens mest nordliga delar. Samtidigt är det en rikt illustrerad, närmast bilddriven, publikation som ger fördjupning kring en utställning: Arktis - medan isen smälter (Nordiska museet 2019-20). I boken medverkar över fyrtio skribenter från olika fakulteter och även konstnärer och andra experter. De längre artiklarna har genomgått granskning av extern läsare, i samverkan med Journal of Northern Studies. Huvudteman som blir belysta ur olika ämnens perspektiv är Arktis som tid och rum, Isens dynamik (ur maringeologiskt djuptidsperspektiv) och historisk antropologi samt Arktis som resurslandskap. Nordiska museets och andra museers samlingar dras in i den mångvetenskapliga undersökningen av spår och rörelser, i ett antal korta essäer om föremål och arkivalier.

Andra världar : Vårt sökande efter extrasolära planeter
- 2018
-
Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- For thousands of years, mankind thought that this was the centre of the Universe. Thanks to our curiosity, imagination and urge to explore, we now know that planets like our Earth are nothing special in the cosmos. The Sun is just one ordinary star among hundreds of billions in our galaxy, the Milky Way.With the world’s most powerful telescopes, we are able to explore more and more of the Universe. What we have found so far has surpassed even the wildest expectations of scientists as well as authors of science fiction. Most stars have planets — it turns out they are more common than we thought. A huge diversity of different worlds is out there, just waiting to be discovered. But, despite all these discoveries, one question remains unanswered: Is there life out there?

Asteroider
- 2017
-
Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- The asteroid 3122 Florence flew past the Earth in early September 2017 and astronomers managed to capture images showing that it had two moons in orbit around it.In this planetarium show we discuss the asteroids in our Solar System, what we know about them, how large they are, how many there are and what we could do if we discovered one on a collision course with Earth.
