58,105 Irish-style double jigs
- 2021
-
Konstnärligt arbete (swepub:mat_score_t)abstract
- These 58,105 tunes come from a collection of 100,001 generated by the folk-rnn (v2) model trained on tens of thousands of transcriptions of Irish traditional dance music. This subset are tunes approved by an artificial critic according to how well they exemplify characteristics of the 365 double jigs in O’Neill’s “1001” (1907) – in reference to a few rough measures. Each tune is numbered in the order of its generation by folk-rnn (v2). Two values accompanying each tune denote its “distance” from the double jigs in O’Neill’s “1001”, and the greatest number of quavers of 24 matching the double jigs in O’Neill’s “1001”. More information about this critic and these tunes can be found in: B.L.T. Sturm, “An Artificial Critic of Irish Double Jigs”, in Proc. AI Music Creativity Conference, Graz, 2021.

A Chest in the Attic
- 2019
-
Konstnärligt arbeteabstract
- When the attic of the Huseby estate house was cleaned in 2008, a large wooden chest was found. It had not been opened since being sealed in India and shipped to Sweden in 1869. Its contents reveal a world of knowledge that changes how we understand the history of colonial India and of Småland 150 years ago, and how these histories intertwine. Joseph Stephens grows up in a British family shaped by the global transformations of the nineteenth century. Joseph was born in Stockholm and, when he is 11 years old, moved to Copenhagen where his father George, folklorist and runologist, had taken up a position at the university. In 1859, at the age of 19, Joseph leaves for Bombay. This is an important port city and a world-leading metropole of trade and finance. Here, Joseph is trained to become a civil engineer under his brother-in-law, an engineer working on one of the world’s largest infrastructure projects: the railways. In the 1860s the Great Indian Peninsula Railway Company (G.I.P.R.) was constructing the trunk lines between India’s trade metropoles, Bombay and Calcutta. The large railway network will eventually interconnect the colonial economy, transporting passengers, goods and troops across the continent. Joseph soon becomes a subcontractor and mobilises labourers and material for smaller projects. After some time he set up his own firm: Joseph Stephens & Company.

A Place in Europe : Proposed project description peered by Project Anywhere
- 2017
-
Konstnärligt arbete (refereegranskat)abstract
- This is not conceived as an exclusive work but rather a demonstrably inclusive one (albeit resistant to the logic of circular reproduction). Within the process of artistic research and a developing practice, new methods might constitute another form of art. The project has been centered upon the idea of a round table at which a number of people with different competences have collaborated productively to build the project. The divergent competences that make up the project team have all contributed to the development of A Place in Europe, and moreover worked to challenge conventional practices and forms of knowledge belonging to the various fields of expertise in order to foster a spirit of experimentation and novelty. The key point of departure for all collaborators has been the value of approaching the topic from a creative base, and in doing so striving to exchange ideas in a productive manner with others, both at the site and within the process of developing the project and presentation. We have also been collectively mindful of the potentially asymmetrical power relations at play in any process during which “we” film and interact with “them”. We do not seek to speak for ”them” but rather use our collective desire to explore a more inclusive society.

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
- 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
-
Ingår i: Comptes rendus. Mathematique. - : Elsevier BV. - 1631-073X .- 1778-3569. ; 357:6, s. 545-551

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.

Action Research in Circus; Learning the Methods of Teaching the Methods of Artistic Research.
- 2011
-
Proceedings (redaktörskap) (refereegranskat)abstract
- In 2011, circus as an art form had only recently entered into the circuits of artistic education at a university level and into artistic research. A working group at the Circus department Stockholm University of the Arts, formely knows as DOCH, has been teaching, analyzing and documenting a particular course that concerned the methods of artistic exploration in circus. The purpose of the project was to address the following question: which pedagogical methods can we develop to prepare students for the methods of artistic exploration and research, specifically in circus? Or in other words: how can we learn the method of teaching the methods of artistic research in the field of circus? The described project was initiated and directed by Marie-Andrée Robitaille. This documentation was written by Camilla Damkjaer in collaboration with Marie-Andrée Robitaille and the presentation was made with the participation of circus students from the bachelor program in circus arts namely Nathalie Bertholio, Quim Giron Figuerola, Patrik Elmnert.

Distributed thermal response tests : New insights on U-pipe and Coaxial heat exchangers in groundwater-filled boreholes
- 2013
-
Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- U-pipe Borehole Heat Exchangers (BHE) are widely used today in ground source heating and cooling systems in spite of their less than optimal performance. This thesis provides a better understanding on the function of U-pipe BHEs and Investigates alternative methods to reduce the temperature difference between the circulating fluid and the borehole wall, including one thermosyphon and three different types of coaxial BHEs.Field tests are performed using distributed temperature measurements along U-pipe and coaxial heat exchangers installed in groundwater filled boreholes. The measurements are carried out during heat injection thermal response tests and during short heat extraction periods using heat pumps. Temperatures are measured inside the secondary fluid path, in the groundwater, and at the borehole wall. These type of temperature measurements were until now missing.A new method for testing borehole heat exchangers, Distributed Thermal Response Test (DTRT), has been proposed and demonstrated in U-pipe, pipe-in-pipe, and multi-pipe BHE designs. The method allows the quantification of the BHE performance at a local level.The operation of a U-pipe thermosyphon BHE consisting of an insulated down-comer and a larger riser pipe using CO2 as a secondary fluid has been demonstrated in a groundwater filled borehole, 70 m deep. It was found that the CO2 may be sub-cooled at the bottom and that it flows upwards through the riser in liquid state until about 30 m depth, where it starts to evaporate.Various power levels and different volumetric flow rates have been imposed to the tested BHEs and used to calculate local ground thermal conductivities and thermal resistances. The local ground thermal conductivities, preferably evaluated at thermal recovery conditions during DTRTs, were found to vary with depth. Local and effective borehole thermal resistances in most heat exchangers have been calculated, and their differences have been discussed in an effort to suggest better methods for interpretation of data from field tests.Large thermal shunt flow between down- and up-going flow channels was identified in all heat exchanger types, particularly at low volumetric flow rates, except in a multi-pipe BHE having an insulated central pipe where the thermal contact between down- and up-coming fluid was almost eliminated.At relatively high volumetric flow rates, U-pipe BHEs show a nearly even distribution of the heat transfer between the ground and the secondary fluid along the depth. The same applies to all coaxial BHEs as long as the flow travels downwards through the central pipe. In the opposite flow direction, an uneven power distribution was measured in multi-chamber and multi-pipe BHEs.Pipe-in-pipe and multi-pipe coaxial heat exchangers show significantly lower local borehole resistances than U-pipes, ranging in average between 0.015 and 0.040 Km/W. These heat exchangers can significantly decrease the temperature difference between the secondary fluid and the ground and may allow the use of plain water as secondary fluid, an alternative to typical antifreeze aqueous solutions. The latter was demonstrated in a pipe-in-pipe BHE having an effective resistance of about 0.030 Km/W.Forced convection in the groundwater achieved by injecting nitrogen bubbles was found to reduce the local thermal resistance in U-pipe BHEs by about 30% during heat injection conditions. The temperatures inside the groundwater are homogenized while injecting the N2, and no radial temperature gradients are then identified. The fluid to groundwater thermal resistance during forced convection was measured to be 0.036 Km/W. This resistance varied between this value and 0.072 Km/W during natural convection conditions in the groundwater, being highest during heat pump operation at temperatures close to the water density maximum.

Distributed thermal response tests on pipe-in-pipe borehole heat exchangers
- 2013

Ingår i: Applied Energy. - : Elsevier BV. - 0306-2619 .- 1872-9118. ; 109:SI, s. 312-320

Tidskriftsartikel (refereegranskat)abstract
- Borehole Thermal Energy Storage systems typically use U-pipe Borehole Heat Exchangers (BHE) having borehole thermal resistances of at least 0.06 K m/W. Obviously, there is room for improvement in the U-pipe design to decrease these values. Additionally, there is a need for methods of getting more detailed knowledge about the performance of BHEs. Performing Distributed Thermal Response Tests (DTRT) on new proposed designs helps to fill this gap, as the ground thermal conductivity and thermal resistances in a BHE can be determined at many instances in the borehole thanks to distributed temperature measurements along the depth. In this paper, results from three heat injection DTRTs carried out on two coaxial pipe-in-pipe BHEs at different flow rates are presented for the first time. The tested pipe-in-pipe geometry consists of a central tube inserted into a larger external flexible pipe, forming an annular space between them. The external pipe is pressed to the borehole wall by applying a slight overpressure at the inside, resulting in good thermal contact and at the same time opening up for a novel method for measuring the borehole wall temperature in situ, by squeezing a fiber optic cable between the external pipe and the borehole wall. A reflection about how to calculate borehole thermal resistance in pipe-in-pipe BHEs is presented. Detailed fluid and borehole wall temperatures along the depth during the whole duration of the DTRTs allowed to calculate local and effective borehole thermal resistances and ground thermal conductivities. Local thermal resistances were found to be almost negligible as compared to U-pipe BHEs, and the effective borehole resistance equal to about 0.03 K m/W. The injected power was found to be almost evenly distributed along the depth.
