Polyrhythmic Organization of Coupled Nonlinear Oscillators

Baier G, Hermann T, Müller M. Polyrhythmic Organization of Coupled Nonlinear Oscillators. In: School of Computing and Mathematical Sciences (Greenwich). Department of Information Systems and Multimedia, ed. IV' 05: Proceedings of the Ninth International Conference on Information Visualisation (IV'05). Los Alamitos, CA, USA: IEEE Computer Society; 2005: 5-10.We study the rhythmic organization of coupled nonlinear oscillators. If oscillators with non-identical internal frequency are coupled, they generate a great variety of periodic and chaotic rhythmic patterns. Sonification of these patterns suggests their characterization in terms of polyrhythms: each oscillatory unit subdivides "measures" of equal or varying length differently. For the case of two coupled oscillators, the organization of these polyrhythms is exemplified as a function of the internal frequency ratio and the coupling strength. Some sonification strategies are presented which aid to detect complex rhythmic relationships between oscillators. The results may be of importance for the analysis of complex multivariate time series like human EEG

A précis of philosophy of computing and information technology

The authors recently finished a comprehensive chapter on “Philosophy of Computing and Information Technology” for the forthcoming (fall 2009) Philosophy of Technology and Engineering Sciences (Ed.: A. Meijers), Volume IX in the Elsevier series Handbook of the Philosophy of Science (Eds.: D. Gabbay, P. Thagard and J. Woods). The purpose of the chapter is to review and discuss the main developments, concepts, topics, and contributors in the intersection between philosophy and computing, as well as provide some suggestions on how to structure the many subcategories within what is loosely referred to as philosophy of computing. In this short synopsis, we will give an outline of the kinds of issues raised in this chapter

Illuminating and measuring personal development: the impact of this work on learning and teaching

This short article gives an overview of a small-scale case study research project based on a 2nd year cohort of students from the Business Information Systems area of the School of Computing, Engineering and Information Sciences at Northumbria University. The aim of this employability module is to prepare students for the recruitment process for their placement year in industry and to inculcate proper professional attitudes and behaviour. The teaching strategy uses the precepts of PDP, and an eportfolio is the vehicle for learning and assessment

Metasynthetic computing for solving open complex problems

Complex systems, in particular, open complex giant systems have become one of major challenges to many current disciplines such as system sciences, cognitive sciences, intelligence sciences, computer sciences, and information sciences. An appropriate methodology for dealing with them is the theory of qualitative-to-quantitative metasynthesis. From the perspective of engineering, we propose the concept of metasynthetic computing. This paper discusses the theoretical frame-work, problem-solving process and intelligence emergence of metasynthetic computing from both engineering and cognition perspectives. These efforts can help one understand complex systems and design effective problem-solving systems. © 2008 IEEE

Proposed Information Systems Accreditation Criteria

The time for accreditation of programs in Information Systems seems appropriate because of the demands of industry and academe. This project is funded by the National Science Foundation and has representatives appointed by the leading societies in computing, Association for Computing Machinery (ACM), IEEE Computer Society (IEEE-CS), Association for Information Systems (AIS), Association for Information Technology Professionals (AITP) and the computing Sciences Accreditation Board (CSAB)
