[CfP SASO'2015] 21-25 September 2015 - Boston Massachusetts
by Frédéric Armetta Feb. 13, 2015

Feb. 13, 2015

****************************************************************************************** CALL FOR PAPERS The Ninth IEEE International Conference on Self-Adaptive and Self-Organizing Systems (SASO 2015) Boston Massachusetts; 21-25 September 2015 https://saso2015.mit.edu/ ****************************************************************************************** Part of FAS* - Foundation and Applications of Self* Computing Conferences Collocated with: The International Conference on Cloud and Autonomic Computing (CAC 2015) The 15th IEEE Peer-to-Peer Computing Conference (P2P 2015) ------------------- Aims and Scope ------------------- The aim of the Self-Adaptive and Self-Organizing systems conference series (SASO) is to provide a forum for the foundations of a principled approach to engineering systems, networks and services based on self-adaptation and self-organization. The complexity of current and emerging networks, software and services, especially in dealing with dynamics in the environment and problem domain, has led the software engineering, distributed systems and management communities to look for inspiration in diverse fields (e.g., complex systems, control theory, artificial intelligence, sociology, and biology) to find new ways of designing and managing such computing systems. In this endeavor, self-organization and self-adaptation have emerged as two promising interrelated approaches. They form the basis for many other self-* properties, such as self-configuration, self-healing, or self-optimization. Systems exhibiting such properties are often referred to as self-* systems. The ninth edition of the SASO conference embraces the inter-disciplinarity and the scientific, empirical, and application dimensions of self-* systems and welcomes novel results on both self-adaptive and self-organizing systems research. The topics of interest include, but are not limited to: - Self-* systems theory: theoretical frameworks and models; biologically- and socially-inspired paradigms; inter-operation of self-* mechanisms; - Self-* systems engineering: reusable mechanisms, design patterns, architectures, methodologies; software and middleware development frameworks and methods, platforms and toolkits; hardware; self-* materials; - Self-* system properties: robustness, resilience and stability; emergence; computational awareness and self-awareness; reflection; - Self-* cyber-physical and socio-technical systems: human factors and visualization; self-* social computers; crowdsourcing and collective awareness; human-in-the-loop; - Applications and experiences of self-* systems: cyber security, transportation, computational sustainability, big data and creative commons, power systems; swarm systems and robotics. - Self-* in education: experience reports; curricula; innovative course concepts; methodological aspects of self-* systems education Contributions must present novel theoretical or experimental results; novel design patterns, mechanisms, system architectures, frameworks or tools; or practical approaches and experiences in building or deploying real-world systems and applications. Contributions contrasting different approaches for engineering a given family of systems, or demonstrating the applicability of a certain approach for different systems, are equally encouraged. Likewise, papers describing substantial innovation or insights in the use and communication of self-* systems in the classroom are welcome. Where relevant and appropriate, accepted papers will also be encouraged to participate in the Demo or Poster Sessions. -------------------- Important Dates -------------------- Abstract submission: May 8, 2015 Paper submission: May 22, 2015 (There will be no extensions of this deadline!) Notification: June 30, 2015 Camera ready copy due: July 17, 2015 Conference: September 21-25, 2015 ---------------------------- Submission Instructions ---------------------------- All submissions should be 10 pages and formatted according to the IEEE Computer Society Press proceedings style guide and submitted electronically in PDF format. Please register as authors and submit your papers using the SASO 2015 conference management system that will be announced on the website. The proceedings will be published by IEEE Computer Society Press, and made available as a part of the IEEE Digital Library. Note that a separate Call for Poster Submissions will also be issued. --------------------- Review Criteria --------------------- Papers should present novel ideas in the cross-disciplinary research context described in this call, clearly motivated by problems from current practice or applied research. We expect both theoretical and empirical contributions to be clearly stated, substantiated by formal analysis, simulation, experimental evaluations, comparative studies, and so on. Appropriate reference must be made to related work. Because SASO is a cross-disciplinary conference, papers must be intelligible and relevant to researchers who are not members of the same specialized sub-field. Authors are also encouraged to submit papers describing applications. Application papers are expected to provide an indication of the real world relevance of the problem that is solved, including a description of the deployment domain, and some form of evaluation of performance, usability, or comparison to alternative approaches. Experience papers are also welcome but they must clearly state the insight into any aspect of design, implementation or management of self-* systems which is of benefit to practitioners and the SASO community. ------------------------------- Conference General Chairs ------------------------------- Howard E Shrobe MIT CSAIL, Cambridge, MA, USA Julie A McCann Imperial College London, UK -------------------- Program Chairs -------------------- Emma Hart Edinburgh Napier University Gregory Sullivan BAE Systems AIT Jan-Philipp Steghöfer University of Gothenburg, Sweden

Re: [Comp-neuro] New computational neuroscience paper on human postural control system in PLoS Comput Biol.
by André Fabio Kohn Feb. 12, 2015

Feb. 12, 2015

Mesoscale neural model of human spinal cord, muscle receptors, muscle dynamics and standing control biomechanics. This recently published paper starts from neuronal ionic channels to model spinal cord neurons and ends at studying human postural control during quiet stance. It represents a closed loop system, with feedback achieved through appropriate muscle spindle and Golgi tendon organ models. It is a mesoscale model and it was successfully validated both at the individual level and the overall behavior level. Spinal cord neurons (motoneurons and excitatory and inhibitory interneurons) are modeled based on ionic channel dynamics, synapses have dynamic properties, afferent and efferent axons introduce delays, muscles and tendons are modeled based on human data, appropriate models of muscle spindles and Golgi tendon organs provide sensory feedback to the spinal cord. Brain commands on the spinal cord are modeled through Gamma point processes with appropriate parameters. >From an overall theoretical view, the system is composed of nonlinear elements, it is stochastic and has delays and is described by approximately 5000 differential equations. Among its many new results, one is that a mixture of intermittent and continuous motor control may arise from the overall dynamics of the closed loop system, without influence from the brain.
