Vibration analysis and control in linear switched reluctance motor

Vibration is one of the major drawbacks of Linear Switched Reluctance Motor (LSRM). Two design techniques to reduce vibration in the LSRM are proposed. A detailed mathematical approach for calculating natural frequency has been outlined. Different techniques to predict the vibration frequencies are analyzed using ANSYS software. The analyzed structures are compared by using experimental and simulation results

Prefigurative politics between ethical practice and absent promise

'Prefigurative politics' has become a popular term for social movements' ethos of unity between means and ends, but its conceptual genealogy has escaped attention. This article disentangles two components: an ethical revolutionary practice, chiefly indebted to the anarchist tradition, which fights domination while directly constructing alternatives; and prefiguration as a recursive temporal framing, unknowingly drawn from Christianity, in which a future radiates backwards on its past. Tracing prefiguration from the Church Fathers to politicised re-surfacings in the Diggers and the New Left, I associate it with Koselleck's 'process of reassurance' in a pre-ordained historical path. Contrasted to recursive prefiguration are the generative temporal framings couching defences of means-ends unity in the anarchist tradition. These emphasised the path dependency of revolutionary social transformation and the ethical underpinnings of anti-authoritarian politics. Misplaced recursive terminology, I argue, today conveniently distracts from the generative framing of means-ends unity, as the promise of revolution is replaced by that of environmental and industrial collapse. Instead of prefiguration, I suggest conceiving of means-ends unity in terms of Bloch's 'concrete utopia', and associating it with 'anxious' and 'catastrophic' forms of hope

Caring for the collective: biopower and agential subjectification in wildlife conservation

types: ArticleCopyright © 2014 PionPost Print. Srinivasan, K. 2014. The definitive, peer-reviewed and edited version of this article is published in Environment and Planning D: Society and Space, Vol. 32, Issue 3, pp. 501 – 517 DOI:10.1068/d13101pThis paper explores turtle conservation in Odisha, India, to map the complicated ways in which animal well-being is pursued in the contemporary world. Using insights from Foucault’s work on biopolitics, it offers an account of conservation as population politics, questioning the entanglement of harm and care that infuses this space of more-than-human social change. In doing this, the paper elaborates the concept of agential subjectification in order to track the mechanisms that underlie the asymmetric circulation of biopower in human–animal interactions and to develop Foucauldian scholarship for the examination of present-day manifestations of the ‘will to improve’.RGS‑IBGCulture and Animals Foundatio

Concentration or representation : the struggle for popular sovereignty

There is a tension in the notion of popular sovereignty, and the notion of democracy associated with it, that is both older than our terms for these notions themselves and more fundamental than the apparently consensual way we tend to use them today. After a review of the competing conceptions of 'the people' that underlie two very different understandings of democracy, this article will defend what might be called a 'neo-Jacobin' commitment to popular sovereignty, understood as the formulation and imposition of a shared political will. A people's egalitarian capacity to concentrate both its collective intelligence and force, from this perspective, takes priority over concerns about how best to represent the full variety of positions and interests that differentiate and divide a community
