Algorithmic Reflections on Choreography
ISSN: 1795-6889 www.humantechnology.jyu.fi Volume 12(2), November 2016, 252–288 ALGORITHMIC REFLECTIONS ON CHOREOGRAPHY Pablo Ventura Daniel Bisig Ventura Dance Company Zurich University of the Arts Switzerland Switzerland Abstract: In 1996, Pablo Ventura turned his attention to the choreography software Life Forms to find out whether the then-revolutionary new tool could lead to new possibilities of expression in contemporary dance. During the next 2 decades, he devised choreographic techniques and custom software to create dance works that highlight the operational logic of computers, accompanied by computer-generated dance and media elements. This article provides a firsthand account of how Ventura’s engagement with algorithmic concepts guided and transformed his choreographic practice. The text describes the methods that were developed to create computer-aided dance choreographies. Furthermore, the text illustrates how choreography techniques can be applied to correlate formal and aesthetic aspects of movement, music, and video. Finally, the text emphasizes how Ventura’s interest in the wider conceptual context has led him to explore with choreographic means fundamental issues concerning the characteristics of humans and machines and their increasingly profound interdependencies. Keywords: computer-aided choreography, breaking of aesthetic and bodily habits, human– machine relationships, computer-generated and interactive media. © 2016 Pablo Ventura & Daniel Bisig, and the Agora Center, University of Jyväskylä DOI: http://dx.doi.org/10.17011/ht/urn.201611174656 This work is licensed under a Creative Commons Attribution-Noncommercial 4.0 International License. 252 Algorithmic Reflections on Choreography INTRODUCTION The purpose of this article is to provide a first-hand account of how a thorough artistic engagement with functional and conceptual aspects of software can guide and transform choreographic practice.

Development of a novel combined catalyst and sorbent for hydrocarbon reforming Abstract A combined catalyst and sorbent was prepared and utilized for steam reforming methane and propane in laboratory-scale systems. The am terial was prepared in the form of small spherical pellets having a layered structure such that each pellet consisted of a highly reactive lime or dolime core enclosed within a porous but strong protective shell made of alumina in which a nickel catalyst was loaded. The am terial served two functions by catalyzing the reaction of hydrocarbons with steam to produce hydrogen while simultaneously absorbing carbon dioxide formed by the reaction. The in situ er moval of CO 2 shifted the reaction equilibrium toward increased H 2 concentration and production.

Web Development Frameworks Ruby on Rails VS Google Web Toolkit
Bachelor thesis Web Development Frameworks Ruby on Rails VS Google Web Toolkit Author: Carlos Gallardo Adrián Extremera Supervisor: Welf Löwe Semester: Spring 2011 Course code: 2DV00E SE-391 82 Kalmar / SE-351 95 Växjö Tel +46 (0)772-28 80 00 [email protected] Lnu.se/dfm Abstract Web programming is getting more and more important every day and as a consequence, many new tools are created in order to help developers design and construct applications quicker, easier and better structured. Apart from different IDEs and Technologies, nowadays Web Frameworks are gaining popularity amongst users since they offer a large range of methods, classes, etc. that allow programmers to create and maintain solid Web systems. This research focuses on two different Web Frameworks: Ruby on Rails and Google Web Toolkit and within this document we will examine some of the most important differences between them during a Web development.
