A Slip of the Machinic Tongue
- 2022
-
Konstnärligt arbete (refereegranskat)abstract
- The title of the book, The Computer as Seen at the End of the Human Age, is a reference to the exhibition “The Machine as Seen at the End of the Mechanical Age”, curated by Pontus Hultén for MoMA in 1968, highlighting how technology was influencing art at a time when mechanical machines were increasingly replaced by electronic and chemical devices. Through its selection of contemporary art works the exhibition thus came to function as a recording of technological history.I never got to see the exhibition since I wasn’t born at the time, but a couple of years ago I came across a curious book with a tin cover. The book was published in connection to the exhibition, and the history recorded between its covers ends at approximately the same time that early computers start to make their way into the art world. In the fifty years that followed, art came to be marked by a digital presence. It was that book, along with an interest in dead media, and a curiosity for art aided by algorithms, that sparked the idea for The Computer as Seen at the End of the Human Age.Here you will encounter new works by a selection of artists, specifically invited to use algorithms/AI to contribute to a continuous, self-reproducing, anachronistic, machine aided recording of history. A way to preserve, revise and/or comment upon digital history from the vantage point of present-day technology or through the lens of imagined future media, perspectives and technologies.The works have been created specifically for the book. Some are based on works by other artists, made in another era, repurposed for our time and technologies. Others are based on redundant technologies, revived and given new functions. Some adopt a critical or political approach to the algorithm and its impact on society. Several utilize it as an opportunity to create unique works for each separate copy of the edition. Thousands of files eventually compiled into 200 unique books, each with a different cover and different contents – generated, aided or influenced by algorithms. Participating artists: Geraldine Juárez, Cornelia Sollfrank/Winnie Soon, Mishka Henner, Shane Hope, !Mediengruppe Bitnik, Rosa Menkman, Rosemary Lee, Olle Essvik, Evan Roth, Jonas Lund, Darsha Hewitt, Carl-Johan Rosén, Linda Hilfling Ritasdatter and Jacek Smolicki.Editor: Olle Essvik

A Slip of the Machinic Tongue : Performative Soundscape Installation
- 2022
-
Konstnärligt arbete (refereegranskat)abstract
- The performance was premiered at 'Digital Existence III: Living with Automation' an international conference at Sigtuna Foundation in Sweden, organized by BioMe project led by prof. Amanda Lagerkvist at Uppsala University and featuring Joanna Zylinska, Katherine Hayles, Nick Couldry, Sarah Pink and others. The performance is based on an essay written for a book 'The Computer as Seen at the End of the Human Age', edited by Olle Essvik (Rojal Förlag, Göteborg 2022). A dialog between several repurposed 'smart' speakers is accompanied by a spontaneously evolving soundscape generated by those devices' electromagnetic fields and micro-currents that make them operational. The piece is a component of an artistic inquiry into other, imperceptible voices and sonic realms that underlie and sustain contemporary technologies of voice recognition, synthesis and biometric capture. The project is part of BioMe: Existential Challenges and Ethical Imperatives of Bio-metric AI in Everyday Lifeworlds led by professor Amanda Lagerkvist at the Informatics and Media Department of Uppsala University.

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.

- Purpose: To determine the phenolic and flavonoid contents of R. sativus rhizome ethanol extract and the hepatoprotective effect of the extract in rats.Methods: Folin–Ciocalteau and aluminum chloride colorimetric tests were used to determine the contents of phenols and flavonoids in the R. sativus extract. Male Sprague-Dawley rats induced with CCl4 to develop hepatotoxicity were treated orally with R. sativus extract for 4 weeks. The antioxidant and anti-inflammatory effects of the extract on the liver were determined by evaluating the concentration of oxidative analytes, serum liver enzymes, and lipids, and hepatic histopathology and cytochrome P450 2E1 expression.Results: R. sativus extract significantly (p < 0.05) reduced the hepatotoxic effect of CCl4 via its antioxidant activities and protection of liver tissues from oxidative damage.Conclusion: The hepatoprotective effects of R. sativus rhizome ethanol extract are attributed to its high phenolic and flavonoid contents.

When the climate apocalypse comes I’ll make it : 16 yr old Hampus' survival month in the forest

- When the climate apocalypse comes I’ll make it: 16 year old Hampus Andersson’s survival month living off the lands and waters in the forests of Norrbotten, Sweden. There is a lot of talk of crisis and apocalypse, due to war, to climate change. Young people worried about their future go on school strike and manifest, around the world. But, when the climate or any other crisis happens, how are these young (and adult) protesters prepared to fend for themselves? How long can you survive without electricity and water in the tap, with access to food in the supermarket? Thinking about all of this, 16 year old Hampus Andersson decided to try to live off the lands and waters for a full month, on his own. If there is such a crisis, would he make it on his own? From mid July to mid August 2019, the experiment went on. He made sure to learn from more experienced and older reindeer herders and others with experience from the forests. Hampus is not completely unaware on how to get access to food in the forest. His father is a Sámi reindeer herder, and his mother’s family are an agriculture family. But until this day he had never done such an experiment. How would he find food, water, shelter? What would be the hardest? Some things that he had never even thought about turned out to be harder than expected. During the stay Hampus documented his everyday life with photos and short films, and posted on his Facebook page and Instagram. This is a film made from those photos and videos, along with an interview by film maker Petri Storlöpare, Slowfilm AB. Hampus speaks of his experiences, thoughts and ideas on how to continue this experiment. Will he try the same in the Arctic winter, with temperatures down to minus 40 Celsius? The film project is supported by Dálkke: Indigenous Climate Change Studies, led by Dr. May-Britt Öhman, Centre for Multidisciplinary Studies on Racism, CEMFOR, Uppsala University.

Working the Aisles: A Life in Consumption
- 2014
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Working the Aisles takes the reader on tumultuous driving trips across the United States and France, on phone sex escapades in San Francisco, on banking battles in Sweden, and many other adventures – including, of course, on trips to supermarkets, where the author has had to ‘work the aisles’. Moving back and forth through time, like a novelist, indeed in something of a memoirist tour de force, the book develops the story of struggle, of poverty and depression, but also of gaiety and desire, of a will to live in spite of it all, and to keep working the aisles. It moves the reader through highs and lows, through episodes of ecstasy and thoughts about suicide, and tells how this particular Everyman ended up sane but sorry.

Characterizations of ground flashes from tropic to northern region
- 2014
-
Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- This thesis portrays new information concerning the cloud-to-ground (CG) lightning flashes or ground flashes produced by thunderclouds. It emphasizes the importance of characterizing lightning studies as the relationship between lightning mechanisms, and of incorporating the influence of geographical location, latitude and storm type. Sweden, Malaysia and USA were chosen as the main locations for field experiments in 2009 to 2011 to gather a significant number of negative and positive CG flashes. This work provided data on a total of 1792 CG lightning flashes (1685 negative and 107 positive ones) from a total of 53 thunderstorms by monitoring both the slow and the fast electric field and the narrowband radiation field at 3 and 30 MHz signals simultaneously. This thesis is comprised of: (i) the relationship of the Low Positive Charge Region (LPCR) and Preliminary Breakdown Pulse (PBP) trains to the occurrence of negative CG, (ii) slow field changes generated by preliminary breakdown processes in positive and negative ground flashes, and (iii) the occurrence of positive and negative ground flashes. It was revealed that the PBP train appeared have a higher strength in the in Sweden. The strength of the PBP train was caused by the LPCR; in contrast, weak PBP trains were characteristic in tropical countries constituting insignificant LPCR and needing little energy to break the “blocking” agent to allow the flash to propagate downward to the ground. The second contribution concerns the characteristics of the PBP train mentioned; this includes novel information for Malaysia. Further, it is stated that there are some different characteristics in the PBP trains in Johor, Malaysia and Florida, USA. The studies of slow field changes generated by preliminary breakdown processes clarifies unclear features concerning the starting position of slow field changes generated by preliminary breakdown processes in positive and negative ground flashes. It was found that the slow field changes did not occur before the initial process of the commencement of preliminary breakdown. Single-station electric field measurements incorporating narrowband radiation field measurement and high resolution transient recording (12 bits) with an accuracy of several nanoseconds, allows one to distinguish between the intracloud activities and the preceding processes of ground flashes. The results for the interstroke intervals, amplitude distribution of subsequent return-stroke (SRS) and the number of strokes per flash in the tropics, subtropics and northern regions were similar. Finally, a significant number of positive return-stroke (RS) electric fields provided statistically significant information on the characteristics of these strokes.

Electric field changes generated by preliminary breakdown pulse for positive lightning ground flashes in Sweden
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- This is the new study of the electric field changes generated by the preliminary breakdown for positive cloud-to-ground flashes which concerning on the association of slow field changes in preliminary breakdown process. In this study, a 107 positive cloud-to-ground lightning flashes recorded from the total of 14 thunderstorms generated by the whole flash were examined. The electric fields were measured with nanosecond resolution by using the slow electric field, fast electric field and narrowband radiation field at 3 and 30 MHz signals simultaneously. Our result shows that there is a pre-starting time, i.e. the duration between the first preliminary breakdown pulse and slow field changes starting point, which is found to be after the first preliminary breakdown pulse. The pre-starting time has the arithmetic mean – 3.0 ms and geometric mean – 1.8 ms, ranging from 0.3 to 21.7 ms. This study is consistent with the latest finding for the slow field changes in negative ground flashes where the slow field changes never start before the preliminary breakdown process.
