Dyadic pulsations as a signature of sustainability in correspondence networks

In this paper, we introduce the concept of dyadic pulsations as a measure of sustainability in online discussion groups. Dyadic pulsations correspond to new communication exchanges occurring between two participants in a discussion group. A group that continuously integrates new participants in the on-going conversation is characterized by a steady dyadic pulsation rhythm. On the contrary, groups that either pursue close conversation or unilateral communication have no or very little dyadic pulsations. We show on two examples taken from Usenet discussion groups, that dyadic pulsations permit to anticipate future bursts in response delay time which are signs of group discussion collapses. We discuss ways of making this measure resilient to spam and other common algorithmic production that pollutes real discussion

EURAU18 Alicante: Retroactive Research: Congress Proceedings

An interdisciplinary research of architecture is something that society demands from our profession. Furthermore, in many countries that are currently immersed in a recessive economic process, it is the only possible solution. In that context, it is urgent to clarify the scope of our projects: Those whose ultimate goal consists of going beyond the limits of other disciplines through the application of architecture. Starting with Architecture’s capacity to learn from other disciplines and to follow their guidelines and techniques, we will build and offer new specific tools. With these new tools, our research will provide the opportunity to challenge and expand the boundaries of those original disciplines. Traditionally, architecture supported itself by various branches of knowledge to advance its proposals: Economic Changes Social organizations Environmental Crisis and Natural Catastrophes Structural Knowledge Artistic Trends New Materials Technological Advances Political positions and Conflicts. While the resulting architectures are excellent examples of applying these areas of knowledge, our interest lies in the reverse process: how the discipline of architecture can cause changes in others. It is an applied research that extends its scope to a prior discourse that originated in the past. That is to say, becomes a Retroactive Research. In the end, the architectural project is an effective document that not only establishes a program but also defines the author as an entrepreneur, understanding this quality as a position that opens the door to different types of practices that architects can exercise: from running a professional architecture office, to teach, to do interior and furniture design, to write, to design digital scenarios, to work in social associations, to collaborate with research centres

Using MapReduce Streaming for Distributed Life Simulation on the Cloud

Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conway’s life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MR’s applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithms’ performance on Amazon’s Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp
