-------- Original-Nachricht -------- Betreff: MTAP (Springer) Special Issue - last call Datum: Tue, 30 Jan 2007 13:32:29 +0100 (CET) Von: Marco Roccetti <roccetti(a)cs.unibo.it> An: multicomm(a)comsoc.org CC: Marco Roccetti <roccetti(a)cs.unibo.it> CALL FOR PAPERS Multimedia Tools and Applications (Springer) Special Issue on New Achievements in Pervasive and Interactive Multimedia Systems and Applications Recent technological advancements have transformed almost any computer, electronic device and appliance into concrete multimedia systems. From a simple laptop to the hype iPod, from wearable computers to wireless sensors, from RFID tags to cell phones, those systems have pervasively got into our homes, offices and places where we have fun, deeply revolutionizing our lifestyle and common habits. Whats really new here is that, surprisingly, not only we can use these devices in a passive way, to listen to music or watch TV for example, but we can use them to customize and adapt all the information we want to receive: We are about to spend our days in an environment saturated with computing and communication devices able to produce and/or adapt a lot of multimedia contents, based on a set of sophisticated interactions these systems carry out with us, as well as with the environment surrounding us. One of the key issue is how to structure this universe of devices and applications, without bothering users with an explicit awareness of the underlying communications and computing technologies, while guaranteeing to them a full control on the results. To this aim, new technical challenges include several different aspects, ranging from the underlying network (is the client-server communication model adequate to support all this?) to the human computer interaction interface (how can a human being simply interact with an embedded system or an RFID tag?) and to the privacy/security mechanisms (how can we ensure privacy in such a pervasive environment?). The goal of this special issue is to collate and disseminate recent and relevant contributions in the area of Pervasive and Interactive Multimedia Systems and Applications including content representation, customization, indexing, access, protection and transmission. Papers are solicited that cover the topics including but not limited to: * Pervasive and interactive multimedia systems including mobile systems, pervasive gaming, and digital TV * Techniques and architectures for streaming media * Multimedia delivery to wireless embedded devices * Mobile content distribution networks * Multimedia QoS support for wired and wireless networks * MAC protocols with multimedia QoS support in wireless networks * Multimedia QoS in peer-to-peer and overlay networks * Online gaming (Service, architecture, protocol, and security) * Privacy and Security Issues * Distributed services middleware and systems for multimedia communications (e.g. Open Service Interfaces) * TV-centric home networks, DTV, and home networked entertainment and games * Information hiding and watermarking * Multimedia Standards, formats and models for multi-channel content distribution * GRID and distributed systems for content production * Web services for content distribution; distribution with P2P architectures * Legal aspects related to digital content (e.g., digital rights management); business, payment and transaction models Only original and unpublished research papers will be considered. Prospective contributors should submit papers in A4/US letter, single column, double space format, up to 30 pages long including figures, tables and references. Authors should submit a pdf version of their manuscript (which should be compressed if the file size exceeds 1 MB) according to the following timetable, directly to the e-mail address of Marco Roccetti: roccetti(a)cs.unibo.it. Camera-ready papers will have to conform to the manuscript style of the target journal (www.springer.com/journal/11042/about). Timetable: Manuscript Submission: February 15, 2007 Acceptance Notification: May 1, 2007 Final Manuscript Due: July 1, 2007 Publication Date: First available issue Guest editors: Marco Roccetti (University of Bologna, IT) Marco Furini (University of Piemonte Orientale, IT) Xiao-Ping Zhang (Ryerson University, Canada) Zhu Liu (AT&T Research Labs, USA) Heather Yu (Panasonic, USA)

-------- Original-Nachricht -------- Betreff: [Tccc] Call for Papers: IEEE/WoWMoM EXPONWIRELESS 2007 (Extended deadline: Feb. 11, 2007) Datum: Mon, 29 Jan 2007 23:12:03 -0600 Von: Yonghe Liu <yonghe(a)cse.uta.edu> An: <tccc(a)cs.columbia.edu> ========================================================= My Best Wishes for a Happy, Healthy, and Successful 2007 and apologies if you receive multiple copies of this message ========================================================= 2nd IEEE Workshop on advanced EXPerimental activities ON WIRELESS networks & systems EXPONWIRELESS - 2007 http://www.ics.forth.gr/EXPONWIRELESS07 18 June, Helsinki, Finland in conjunction with IEEE WoWMoM 2007 (http://ieee-wowmom.tml.hut.fi/) CALL FOR PAPERS Wireless networks represent a challenging and ever growing research area. In these systems the interactions among the different network layers are very complex and their effects on the overall performance are not easy to accurately identify. Additionally, many simplifying assumptions considered in analytical studies do not hold in practise. Experimental activities involving the development of systems and device prototypes and the collection and analysis of measurements from actual networks can provide insight on the behaviour of such systems in realistic environments, which can be beneficial for understanding how cross-layer interactions impact in practise the overall performance, for deriving realistic simulation models, for analyzing particular phenomena and evaluating algorithms and protocols, and for exploring the design choices in building actual wireless networks. Such activities are pivotal for researchers, developers, service managers and providers, as well as for end users involved in the evolution of these networks. After a successful first event last year, EXPONWIRELESS 2007 aims to again bring together all the aspects related to experimental activities on wireless networks, creating a forum where researchers, vendors, providers and users can exchange ideas on past experience, current requirements, and future visions, that are important for the development of new protocols, algorithms, devices and systems. High quality papers discussing original and innovative experimental activities on wireless networks are solicited for submission. The main topics of the workshop are (but are not limited to): * Device prototypes for wireless BANs, PANs, LANs, and MANs * Prototype implementation of wireless/mobile networks and systems * Deployment and experience with multi-hop multi-radio wireless mesh networks * QoS for real-time voice/video in wireless networks * Differentiated services in wireless multimedia networks * Systems and methods for collecting and analyzing measurements in wireless networks * Power control and channel assignment * Algorithms for self-configuration and self-management of beyond-3G systems * Seamless internetworking and architectures for beyond-3G systems * Handoff and mobility management in beyond-3G systems * Energy-efficient protocols and power management algorithms * Wireless security * Wireless vehicular networks * Wireless/Mobile applications and services * Middleware platforms for wireless/mobile environments * Mobility models * Location services * Positioning and tracking technologies PAPER SUBMISSION AND PUBLICATION Submitted manuscripts should adhere to the IEEE double-column standard format with 10pt font size for texts. Authors should use only standard fonts, i.e., Times Roman, Courier, Symbol, and Helvetica, or equivalent. The maximum length of the manuscript is 6 pages. This limit includes figures, appendix, bibliography, etc. Papers significantly exceeding this limit will be automatically rejected. All papers must be submitted in PDF format to the address exponw(a)ics.forth.gr. Accepted papers will be published by the IEEE in the combined WoWMoM 2007 workshop proceedings.

-------- Original-Nachricht -------- Betreff: [Tccc] STREAM 2007 || First International Workshop on Data Stream Processing || July 1-6, 2007 - Silicon Valley || Datum: Sun, 28 Jan 2007 16:35:13 -0500 (EST) Von: andy(a)confpromo.com An: tccc(a)cs.columbia.edu CC: pdini(a)cisco.com Invitation, Please consider to contribute and distribute to the appropriate groups the following: CALL FOR PAPERS The First International Workshop on Data Stream Processing STREAM 2007 July 1-6, 2007 - Silicon Valley, USA see: http://www.iaria.org/conferences2007/STREAM.html in conjunction with The Second International Conference on Digital Telecommunications ICDT 2007 see: http://www.iaria.org/conferences2007/ICDT07.html Important deadlines: Submission deadline: February 20, 2007 Notification of acceptance: March 10, 2007 Registration/camera ready: March 31, 2007 On online monitoring applications, in which continuous queries operate in near real-time over rapid and unbounded "streams" of data such as telephone call records, sensor readings, web usage logs, network packet traces, are fundamentally different from traditional data management. The difference is induced by the fact that in applications such as network monitoring, telecommunications data management, manufacturing, sensor networks, and others, data takes the form of continuous data streams rather than finite stored data sets. As a result, clients require long-running continuous queries as opposed to one-time queries. These requirements lead to reconsider data management and processing of complex and numerous continuous queries over data streams, as current database systems and data processing methods are nit suitable. Event stream processing is a new paradigm of computing that supports the processing of multiple streams of event data with the goal of identifying the meaningful events within those streams The International Workshop on Data Stream Processing, STREAM 2007, brings together practitioners and researchers for discussion and work on the emerging aspects pertaining to new algorithms for data stream processing, optimization, and system design methodologies using these techniques. TOPICS OF SPECIAL INTEREST (but not limited to): Fundamentals on data stream processing Data stream processing and event stream processing Continuous query languages Time management in data stream systems Aggregated queries support Query processing with multiple, continuous, rapid, time-varying data streams Processing frequent item set discovery queries Real-time stream data processing Network-aware operator placement for stream-processing systems Integrating database queries and Web searches Scalable Distributed Stream Processing Optimization of data stream processing Performance and overhead in data stream processing QoS adaptation in data stream systems Adaptive query processing in data stream Interactive distributed data stream processing and mining Data stream management systems Control theory on stream processing Processing high-speed data streams Stream processing in production-to-business software Multi-site cooperative data stream analysis Grid-based data stream processing Hyper databases for P2P data stream processing Sensor data stream processing in health monitoring Processing and sharing data streams in Grid-based P2P infrastructures INSTRUCTIONS FOR THE AUTHORS The STREAM 2007 Proceedings will be published by IEEE Computer Society Press, posted on IEEE Xplore Digital Library, and indexed with major indexes. Regular papers Only .pdf or .doc files will be accepted for paper submission. Every submission will receive an ID from the EDAS system.

Once you receive the notification of paper acceptance, you will be provided by the IEEE CS Press an online author kit with all the steps an author needs to follow to submit the final version. The author kits URL will be included in the letter of acceptance. Technical marketing/business/positioning presentations The conference initiates a series of business, technical marketing, and positioning presentations on the same topics. Speakers must submit a 10-12 slide deck presentations with substantial notes accompanying the slides, in the .ppt format (.pdf-ed).

The combination of mobile and ubiquitous computing is emerging as a promising new paradigm with the goal to provide computing and communication services all the time, everywhere, transparently and invisibly to the user, using devices embedded in the surrounding physical environment. In this context, the communication devices, the objects with which they interact, or both may be mobile. The implementation of such a paradigm requires advances in wireless network technologies and devices, development of infrastructures supporting cognitive environments, and discovery and identification of ubiquitous computing applications and services. We are seeking research papers, technical reports, dissertation etc for these interdisciplinary areas. The goal of the UBICC journal is to publish the most recent results in the development of system aspects of ubiquitous computing. Researchers and practitioners working in this area are expected to take this opportunity to discuss and express their views on the current trends, challenges, and state of the art solutions addressing various issues in this area. *Topics of interest include, but are not limited to* 1.

-------- Original-Nachricht -------- Betreff: SIGOPS-ANNOUNCE supplemental posting (SASO 2007 Call for Papers) Datum: Fri, 26 Jan 2007 08:33:59 -0800 Von: Geoff Voelker <voelker(a)CS.UCSD.EDU> Antwort an: Geoff Voelker <voelker(a)CS.UCSD.EDU> An: SIGOPS-ANNOUNCE(a)LISTSERV.ACM.ORG (This CfP is sent by Hermann de Meer, University of Passau, Germany. Apologies for multiple copies.) ***************************************************************** Call for Papers SASO 2007 International Conference on Self-Adaptive and Self-Organizing Systems Boston, Mass., USA, July 9-11, 2007 http://projects.csail.mit.edu/saso2007/ Sponsored by IEEE Computer Society, Task Force on Autonomous and Autonomic Systems (approval pending) in cooperation with ACM SIGOPS (approval pending) and ISCE Research The complexity of current computer systems has led the software engineering, distributed systems and management communities to look for inspiration in diverse fields (e.g., robotics, artificial intelligence or biology) to find new ways of designing and managing networks, systems and services. In this endeavor, self-organization and self-adaptation have emerged as two promising facets of a paradigm shift. Self-adaptive systems work in a top-down manner. They evaluate their own global behavior and change it when the evaluation indicates that they are not accomplishing what they were intended to do, or when better functionality or performance is possible. Self-organizing systems work bottom-up. They are composed of a large number of components that interact locally according to simple rules. The global behavior of the system emerges from these local interactions, and it is difficult to deduce properties of the global system by studying only the local properties of its parts. This edition of SASO will focus on engineering, as opposed to speculative and conjectural visions. Contributions should present novel theoretical results, or practical experience with building systems, tools, frameworks, etc. Contributions contrasting different approaches for engineering a given family of systems, or demonstrating the applicability of a certain approach for different systems are particularly encouraged. Topics o Self-* properties: - self-organization - self-adaptiveness - self-management - self-monitoring - self-tuning - self-repair - self-configuration - etc. o Theories, frameworks and methods for self-* systems o Management and control of self-* systems o Robustness and dependability of self-* systems o Engineering and control of emergent properties in self-* systems o Biologically and socially inspired self-* systems Systems & Technologies o P2P applications o Mobile robots o Sensor networks o Mobile ad hoc networks o Grids o Embedded systems, ubiquitous computing o Autonomic computing, autonomic communications o Computer networks, telecommunication networks o Multi-agent systems o E-business systems and services o Complex adaptive systems Research Communities o Distributed artificial intelligence o Networking o Software engineering o Distributed systems o Integrated management o Robotics o Knowledge-based systems o Machine learning o Control theory o Mathematical optimization Organization General Co-Chairs: Ozalp Babaoglu, University of Bologna, Italy Howard E.

[Fwd: ACF-Members: CFP 1st International Workshop on Policy-based Computing (PBAC 2007)]
by Lars Wolf 26 Jan '07

26 Jan '07

-------- Original-Nachricht -------- Betreff: ACF-Members: CFP 1st International Workshop on Policy-based Computing (PBAC 2007) Datum: Fri, 26 Jan 2007 04:53:11 -0000 Von: Duncan Johnston Watt <Duncan(a)enigmatec.net> An: <acf-members(a)autonomic-communication-forum.org> Call for papers 1st International Workshop on Policy-Based Autonomic Computing- PBAC 2007 http://cms1.gre.ac.uk/conferences/pbac2007 Sponsors: IEEE and ACM A one-day workshop to be held at: The 4th IEEE International Conference on Autonomic Computing (ICAC 2007 - http://www.acis.ufl.edu/~icac2007/index.shtm) June 11-15, 2007, Jacksonville, Florida, USA The theme and scope of the workshop Policy-based computing is one of many techniques used to implement autonomic computer systems. The business function is expressed in terms of workflow (logic + actions) or behavioural rules to be performed in response to certain situations, which is decoupled from the implementation mechanism. The mechanisms are fixed at design time, but the actual run-time behaviour is decided by the policy. This facilitates contextual awareness as the policy may take account of various environmental inputs from sensors and external software systems. Policy-based mechanisms are also very useful in specifying system behaviour – such as when specifying Service Level Agreements, and subsequently monitoring whether these agreements have been adhered to. Policy-based configuration is highly versatile and generally applicable across a very wide application space. When compared with other autonomics techniques, policies represent one of the lowest risk and lowest cost solutions; because there is relatively low complexity. The workshop intends to discuss all aspects of using policies in the context of autonomic computing. We invite papers reporting novel contributions to policy-based computing within an autonomics context. Submissions must describe original work that has not been published, accepted or submitted for publication elsewhere. Indicative keywords and themes Policy languages and tools Policy languages and semantics. Policy frameworks for autonomic computing. Platforms and tools to aid the development of policies and policy-based systems. Visualisation tools - for policy configuration and also for policy execution traces. Policy-autonomics concepts Multiple-policy systems. Combining policy-based computing with other autonomics techniques. Dynamic adaptation / evolution of policy configuration. Automated evaluation of policies. Models of policy negotiation and collaboration. Policy-based applications Development and verification of policy-based applications. Autonomic applications of policy-based computing. Feasibility and requirements for the deployment of policy-based solutions. Policy-based virtualisation tools. Context and environmental awareness in policy systems Context-aware privacy policies. Policies for dealing with trust and risk in autonomic systems. Policy conflict management. Please note that the keywords and themes are indicative and we welcome submissions in other relevant areas. However, it is intended that the workshop will have an empirical / experiential emphasis, and thus preference will be given to papers that are supported by an implementation, prototypes and/or simulations. Also of interest are theoretical approaches to the study of policy languages and semantics with a view towards exploitation in an autonomics context. Target audience Policy-based computing in autonomics is equally relevant and important to industry, research and academia. The workshop will be of great interest to a practitioner audience although no particular level of expertise is expected and we welcome multi-disciplinary contributions. We intend that the workshop will provide a forum for focussed discussion of policy-based computing as a technique for implementing autonomic systems, and hope that delegates will be able to exchange ideas concerning ways in which policies can be developed and deployed. The workshop is expected to have the effect of promoting the use of policies and encouraging further research in this area. Submissions Full papers of up to 10 pages should be formatted in the standard IEEE two-column conference proceedings format. Shorter work-in-progress papers (up to 4 pages) will also be considered based on individual merit. Actual submission will be via on-line upload to the website. Publication The workshop proceedings will be published in the Whitestein Series on Software Agent Technologies and Autonomic Computing. In addition, authors of selected papers from the workshop will be invited to submit expanded versions of their papers for inclusion in a forthcoming ACM Transactions on Autonomous and Adaptive Systems (TAAS) special issue on Policy-based Autonomic Computing.
