Konferensbidrag (refereegranskat)abstract
- The phenomenon of a “mediated cosmopolitanism” has mainly been studied from a perspective that attempts to discern the extent to which various messages of the media succeed or fail in establishing moral solidarity with “the distant other”. This perspective misses two crucial points worthy of pursuing when attempting to understand the relationship between media and cosmopolitanism. Firstly, it still remains rather unclear what sense audiences and users make of the globalizing potential of the contemporary media landscape. Secondly, cosmopolitanism cannot solely be conceptualized as a moral obligation across vast distances, but needs also to be understood as a form of capital, as social fields become increasingly transnational. By understanding users and audiences of potentially global media as contextualized social agents we engage with the relationship between cosmopolitanism and the media from a new vantage point. In departing from the media-centric tendencies in the research area, we turn to the question of how classified social agents classify the contemporary media landscape as gateways to the wider world. What emerges in our qualitative and quantitative data is a pattern of social reproduction – agents strong on cultural capital are particularly prone to approach the media landscape as an avenue for the generation of cosmopolitan capital. There is thus reason to question the universalizing rhetoric pertaining to notions of a “mediated cosmopolitanism” and study the ways in which agents’ orientations in the media landscape are part of strategies of social reproduction.

(Mediated) cosmopolitanism as symbolic violence
- 2014
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The notions of a “mediated cosmopolitanism”, a “global imagined community” and an “imagined cosmopolitanism” speak of a cosmopolitan opportunism gaining ground in contemporary media and communication studies. This line of research tends to epistemologically situate human beings exclusively as users or audiences of media. The risk by such a media-centric focus is to confine oneself to the question of “what the media does to people”. By understanding users and audiences of potentially global media as contextualized social agents we engage with the relationship between cosmopolitanism and the media from a different vantage point. Our media sociological perspective insists on accounting for social context, and so we turn to the question of how classified social agents classify the contemporary media landscape as gateways to the wider world. What emerges in our qualitative and quantitative data is a pattern of social reproduction by way of cultural distinction – agents strong on cultural capital is particularly prone to approach the media landscape as an avenue for cosmopolitan socialization. There is thus reason to question the universalizing rhetoric pertaining to notions of a “mediated cosmopolitanism”.

Trading cultural capital for cosmopolitan capital : media practice as reconversion work in a globalizing world
- 2016
-
Konferensbidrag (refereegranskat)abstract
- Various media allow people to build transnational networks, learn about the world and meet people from other cultures. In other words, media may allow one to cultivate a cosmopolitan capital. However, far from everyone is recognizing this potential. This study argues that cosmopolitan ‘readings’ of the contemporary media landscape should be understood in relation to cultural capital. Analyses from a national survey and in-depth interviews, conducted in Sweden, disclose a tendency among those in possession of cultural capital to recognize and exploit cosmopolitan capital in their media practices. Those in dispossession of cultural capital are significantly less prone to approach the media in this way. Relying on various media practices in order to exchange one capital for another exemplifies what Bourdieu called reconversion strategies. As social fields become more global, media offer opportunities for those occupying positions of relative (cultural) privilege to remain privileged – to change in order to conserve.

- Conformance testing is a formal and structured approach to verifying system correctness. We propose a conformance testing algorithm for cyber-physical systems, based on the notion of hybrid conformance by Abbas and Fainekos. We show how the dynamics of system specification and the sampling rate play an essential role in making sound verdicts. We specify and prove error bounds that lead to sound test-suites for a given specification and a given sampling rate. © 2016 IEEE.

Towards an Approximate Conformance Relation for Hybrid I/O Automata
- 2016

Ingår i: Proceedings of the The First Workshop on Verification and Validation of Cyber-Physical Systems. - Sydney : Open Publishing Association. ; , s. 53-64
-
Konferensbidrag (refereegranskat)abstract
- Several notions of conformance have been proposed for checking the behavior of cyber-physical systems against their hybrid systems models. In this paper, we explore the initial idea of a notion of approximate conformance that allows for comparison of both observable discrete actions and (sampled) continuous trajectories. As such, this notion will consolidate two earlier notions, namely the notion of Hybrid Input-Output Conformance (HIOCO) by M. van Osch and the notion of Hybrid Conformance by H. Abbas and G.E. Fainekos. We prove that our proposed notion of conformance satisfies a semi-transitivity property, which makes it suitable for a step-wise proof of conformance or refinement.

Avoidance of resonances in a semi-guy-wired vertical axis wind turbine
- 2014
-
Ingår i: Proceedings of EWEA 2014 - Annual Event (Conference), Barcelona, 10-13 March 2014.
-
Konferensbidrag (refereegranskat)abstract
- Resonance analysis for a vertical axis wind turbine is performed. The turbine may be described as semi-guy wired, being bolted stiffly to the ground as well as supported by guy wires. The influence of the first mode eigen frequency of the guy wires and how it is affected by wind load is examined. Using beam theory, an analytical model for calculating the first mode eigen frequency of the guy wire for different wind loads is derived. The analytical model is verified with FEM-simulations and then used to assemble a diagram showing how to combine the wire size, inclination angle and pre-tension for an eigen frequency range over the 3P load for nominal rotational speed and for a certain effective spring force acting on the tower. This diagram, here called an EA-T diagram, may be used as a quick tool for comparing wire setups and a similar diagram can be used for other guy wired structures.

Noise directivity from a vertical axis wind turbine
- 2015

Ingår i: Proceedings of the 6th International Conference on Wind Turbine Noise. - New Brighton, UK : INCE/Europe.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The directivity of wind turbine noise is of widespread interest and has received attention over an extended period. The reason for this is partly that noise optimization procedures can be implemented in order to increase the efficiency of the power output. Although directivity of horizontal axis wind turbines (HAWTs) are well understood, the directivity pattern around vertical axis wind turbines (VAWTs) are less well investigated.This paper presents measurements of directivity on a 200 kW VAWT, a so called H-rotor, with variable speed and a tower height of 40 m. The turbine, which is situated in a flat agricultural landscape close to Falkenberg at the Swedish west coast, is one of the world’s largest today operational VAWTs. Experimental results as well as a theoretical model based on the turbulent-boundary-layer trailing-edge (TBL-TE) noise suggest higher noise levels upwind of the rotor and the lowest noise levels in the perpendicular directions. Moreover, modulation analysis of the measurements indicates the presence of modulations but the results are inconclusive.

Noise Propagation from a Vertical Axis Wind Turbine

Konferensbidrag (refereegranskat)abstract
- Initial noise measurements were performed on a 200kW vertical axis wind turbine (VAWT) and results were compared to that of a Vestas V27, a similar size horizontal axis wind turbine (HAWT). Multiple recording units were placed in line downwind of the turbine to investigate noise propagation. The frequency distribution of the noise were analyzed indicating that the VAWT has lower relative levels for frequencies under 3000 Hz, especially within 600-1200 Hz. Furthermore, VAWT noise seems to occur more around the same frequencies as the natural background noise, increasing masking probability. Results from propagation measurements seemed to indicate that noise declines more rapidly with distance for the VAWT then for the reference HAWT, possibly explained by the lower levels at low frequencies. Further investigation is needed to establish these differences and the 200 kW VAWT creates an opportunity doing so utilizing arguably the largest operational VAWT existing today.
