ACM BuildSys 2017 Call for Paper
by Polly Huang 07 May '17

07 May '17

-- Our sincere apologies if you receive duplicates of the call -- ============================================== Dear Colleagues, Please see below the Call for Papers for ACM BuildSys 2017. We enthusiastically look forward to your submissions on advancements in systems for any aspect of the built environment. Our sincere apologies if you receive multiple copies of this email. BuildSys has established itself as the premier conference for researchers and practitioners working to develop and optimize smart infrastructure systems that are driven by sensing, computing, and control functions. The review process is very thorough, and publications are considered to have the same value as journal publications in engineering fields. November 8-9, 2017 Delft, The Netherlands | co-located with ACM SenSys 2017 http://buildsys.acm.org/2017/ Important Dates: Abstract Registration: June 9, 2017 (11:59 PM AoE) Paper Submission Deadline: June 16, 2017 (11:59 PM AoE) Acceptance Notification: August 18, 2017 Camera-Ready Deadline: September, 2017 Conference Dates: November 8-9, 2017 ** For the abstract registration, you only need to enter the title of the paper, the list of authors and their email addresses, the PC conflicts, and a brief abstract (~150-250 words). After registering the paper's abstract, you will have an additional week to upload the PDF file of the paper (either a 10-page Full paper or a 4-page Notes paper). Advances in the effective integration of networked sensors, building controls, and physical infrastructure are transforming our society, allowing the formation of unprecedented built environments and interlocking physical, social, cyber challenges. Built environments, including buildings and critical urban infrastructure, account for over half of society’s energy consumption and are the mainstay of our nation’s economy, security and health. As a result, there is a broad recognition that systems optimizing explicitly for the built environment are particularly important in improving our society, e.g., by increasing its sustainability and enhancing people’s quality-of-life. These systems represent the foundation for emerging “smart cities”. The 4th ACM International Conference on Systems for Energy-Efficient Built Environments (BuildSys 2017) will be held November 8-9, 2017 at Delft, The Netherlands. We invite original contributions in the areas of intelligent systems and applications for the built environment. BuildSys particularly emphasizes approaches that improve energy efficiency, reduce costs, increase performance, and add novel functionality for improving users’ comfort and experience. BuildSys’ scope is broad, encompassing all systems within the built environment of the urban fabric, including not only buildings but also critical infrastructure systems, such as water, power, lighting, communications, and transportation that will make up the “smart cities” of the future. Submission Types: We solicit three types of original submissions: * Regular papers for oral presentation (10 pages) * Notes papers for oral presentation (4 pages) * Technical posters and demos will be solicited via a separate call (2 pages) Topics: Papers are invited in all emerging aspects of information-driven systems for the built environment. Topics of interest include but are not limited to the following: · Applications in smart and connected communities; · Sensing and control for urban infrastructure systems; · Novel sensor methodologies, techniques, and tools; · Sensing and control of electrical, gas, and water loads; · Improved user interfaces to built infrastructure; · Modeling, simulation, optimization, and control of heating, cooling, lighting, ventilation, water usage and other resource flows in built environments; · Sensor systems and applications that enhance energy efficiency, energy reliability, durability and comfort; · Systems that integrate infrastructure with the smart grid to offer demand response and ancillary services; · Distributed generation, alternative energy, renewable sources, and energy storage in buildings; · Emerging standards for data collection, energy control, or interoperability of disparate devices or systems; · Sensing, modeling, and predicting the urban heartbeat including sounds, movements, and radio spectrum; · Human in the loop sensing and control for efficient usage of electricity, gas, heating, water; · Sensor systems for reliable occupancy counting; · Long-lived and energy harvesting sensor systems; · Scalable indoor localization and contextual computing; · Security, privacy, safety, and reliability in built systems; · Empirical studies of city-scale wireless communications.

RIPE 74 call for late submissions, LTs, and one tutorial and BoF
by Benno Overeinder 14 Apr '17

14 Apr '17

Dear colleagues, Brief version: The RIPE PC invites submissions for plenary, tutorial, BoF and Lightning Talks. Longer version: As distinct from previous RIPE meetings, the RIPE Programme Committee decided to keep two plenary slots open for so-called “late submission”. These plenary slots gives the community the opportunity to submit presentations that report on recent developments, issues, security incidents, etc., that are relevant to the RIPE audience. Independent from the realisation of late submissions, the PC has received a fair amount of high-quality submissions for the first deadline on March 12th. From these submissions, we have selected 14 presentations to complete the RIPE 74 plenary programme and no second CFP with a deadline in April was required. For the tutorials and BoFs we have one slot for each available: - Monday morning, 2 hour tutorial slot - evening, 1 hour BoF slot Also please consider to submit Lightning Talks for the Monday plenary. During the week of the RIPE meeting we will accept LTs for Tuesday and Friday. Please submit your plenary “late submission”, tutorial or BoF submission via the PC submission system, https://ripe74.ripe.net/submit-topic/submission-form/. The deadline for the submissions is *April 26th*. Kind regards, Benno Overeinder RIPE PC Chair https://ripe74.ripe.net/programme/ripe-pc/ -------------------->>><<<-------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. RIPE 74 will take place from 8-12 May 2017 in Budapest, Hungary. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 74. See the full descriptions of the different presentation formats, https://ripe74.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 26 April 2017. Proposals submitted after this date will be considered depending on the remaining available space in the programme. The PC is looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange - Connected Things (aka. Internet of Things - IoT) Submissions RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour - Lightning talks: 10 minutes total for both presentation and any discussion The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe74.ripe.net/submit-topic/submission-form/. - Lightning talks should also be submitted using the meeting submission system (https://ripe74.ripe.net/submit-topic/submission-form/) and can be submitted any time up to and including the meeting week. Allocation of lightning talks will start a few days before the meeting, and will continue throughout the meeting. During the meeting, they may be announced on the day before the talk or even on the same day as the talk. - Lightning talks should also be submitted using the meeting submission system (https://ripe74.ripe.net/submit-topic/submission-form/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice, in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. - Due to potential technical issues, presenters/panellists should be physically present at the RIPE Meeting. If you have any questions or requests concerning content submissions, please email pc [at] ripe [dot] net. -- Benno J. Overeinder NLnet Labs http://www.nlnetlabs.nl/
