Water Birds: Compositional collaboration with clarinets, wireless sensors, and RTcmix
No full text"Water Birds" is an interactive composition for Bb and bass clarinet, computer music and wireless sensor system by Mara Helmuth and Rebecca Danard. A wireless sensor network with infra-red sensors responds to the clarinetist’s movements, and sends data into MaxMSP for signal processing control. The wireless sensor configuration was developed by Jung Hyun Jun, Talmai Oliveira, Amitabh Mishra, Ahmad Mostafa and Dharma Agrawal, and extended for this project in collaboration with Helmuth. MaxMSP Mxj Java objects were created to receive data from the programmed tmote sensors. Helmuth’s score consists of four sound-generating ideas. Her Max patch and RTcmix scripts process the clarinet sound with spectral delays through the rtcmix~ plugin for Max5. Danard created a working score solidifying her decisions about materials played and order of events. Helmuth and Danard’s interactive compositional process allowed to piece to evolve organically into a work commenting on the interaction of people, nature and technology.Conference PaperPre-prin
Eccentricity and Vulnerability: Helmuth Plessner’s Philosophical and Political Anthropology
No full textThis text is a written and extended version of the lecture I gave on 7 November 2017 at the First Spanish-Serbian Workshop on Philosophy and Social Theory, ‘Engaging Vulnerability and Exclusion. Rethinking the Subject in the 21st Century’. On that occasion, I focused on Helmuth Plessner’s conception of the individual and underlined the connection between the notions of ‘eccentricity’ and ‘vulnerability’ from that point of view. The present version also explores at the very end that same connection from the perspective of relations between nations and peoples as it is thematized by Plessner himself in the last chapter of his 1931 book Macht und menschliche Natur. In this way, I try to contribute to the revitalization of the reception of Plessner’s philosophical and political anthropology, which I have been working on during recent years, as well as to reclaim the importance of the so-called ‘continental philosophy’ with regard to the discourse on the vulnerability issue.This chapter will focus on "Macht und menschliche Natur", Plessner’s last book of the Weimar period, published just two years before the collapse of the Republic and the content of which is related to another two major figures of German intellectuality during this epoch of upheaval: the author of "Sein und Zeit", Martin Heidegger, and Carl Schmitt. I will examine the affinities and discrepancies which may be found between Schmitt and Plessner regarding the meaning which the conceptual pair friend-enemy acquires according to both authors. Schmitt understood it as the difference which determines human groupings, whereas Plessner comprehended it as a relation which does not institute identity and has not only to do with groups, but also with individuals.Depto. de Filosofía y SociedadFac. de FilosofíaFALSEpu

Frequency Domain Multiplexing for Large-Scale Bolometer Arrays
No full textAbstract The development of planar fabrication techniques for superconducting transition-edge sensors has brought large-scale arrays of 1000 pixels or more to the realm of practicality. This raises the problem of reading out a large number of sensors with a tractable number of connections. A possible solution is frequency-domain multiplexing. I summarize basic principles, present various circuit topologies, and discuss design tradeoffs, noise performance, cross-talk and dynamic range. The design of a practical device and its readout system is described with a discussion of fabrication issues, practical limits and future prospects
