Seminar in partnership with INES 2.0: Energy Efficient Wavelength Dimensioning and Placement of Virtualized BaseBand Processing Functions in Cloud-Fog RAN over TWDM-PON for the Support of 5G Internet

November 30, 2017 4:32 pm

When: Friday, December 15h, 2017, 3:00 PM.

Speaker: Rodrigo Izidoro Tinini (IME/USP).

Abstract: In the context of future Cloud Radio Access Networks (CRAN), optical networks will play an important role to provide the required transport capacity between cell-sites and processing pools, especially for future 5G scenarios. For instance, using CPRI fronthaul technologies a single antenna element can generate data up to 24.3Gbps even with current configurations of radio transmissions, and it is expected to generate up to Tbps with the advance of technology. So, the transport segment of a 5G network needs to be accurately planned to accomodate all the generated traffic. In this work, we propose the use of a Passive Optical Network jointly with the emergent paradigms of Fog Computing and NFV to energy-efficiently support the high traffic transported in emergent mobile networks in an hybrid architecture called Cloud/Fog RAN (CF-RAN) that allows local and remote baseband processing. We introduce an Integer Linear Programming (ILP) model to schedule the processing of CPRI demands among the processing nodes of the network and turn on or off processing functions on demand. Our approach is able to accomodate demands on the nodes of the network in the most energy efficient way. We compare our results with CRAN and distributed architectures (DRAN) and show that an energy efficient planning can achieve considerable gains in energy consumption.

Painel: Ética em IA e Cidades Inteligentes

November 6, 2017 11:09 pm
A pesquisa em Cidades Inteligentes, que compreende a utilização de Tecnologia da Informação para a melhoria da qualidade de vida nas cidades, possui um enorme potencial para contribuir positivamente com as nossas cidades e seus cidadãos. Dentre as tecnologias que terão um enorme impacto em nossas vidas nas próximas décadas, encontram-se o monitoramento em tempo-real e a Inteligência Artificial (IA). No entanto, essas mesmas tecnologias podem trazer sérios problemas à privacidade e segurança desses mesmos cidadãos e, caso não aplicadas corretamente, podem exacerbar ao invés de diminuir as desigualdades sociais e os preconceitos já existentes na sociedade.
 
INCT da Internet do Futuro para Cidades Inteligentes, traz 5 especialistas para discutir aspectos éticos das Cidades Inteligentes e da IA no IME-USP. Contamos com a sua presença ou e-presença!
 
Quando: Sexta-feira, 10 de Novembro, das 15:00 às 16:30.

Image-based information visualization (or how to unify SciVis and InfoVis)

September 27, 2017 3:48 pm

Prof. Alex Telea offered a presentation on how to unify scientific visualization (SciVis) and information visualization (InfoVis).

When: Thursday, September 28th, 2017, 2:00 PM.

Where: Auditório Jacy Monteiro, IME- USP.

Abstract: For decades, scientific visualization (SciVis) and information visualization (InfoVis) have been related, but still distinctly separated disciplines. Methods and techniques in the two areas have developed relatively separately, causing an arguably unnecessarily separation in the visualization field. Attempts for unification exist, but are largely based on heuristics, and subject to critique from both the SciVis and InfoVis angles. In this talk, we argue that this separation is not necessary, and, up to large extents, artificial. More specifically, we argue that the difference between SciVis and InfoVis is not a matter of design decisions only, but, more centrally, a matter of representing the structure of large data collections by means of smooth, continuous, encodings. We present a way to cast InfoVis along the same principles as the more classical SciVis, based on a continuous, multiscale, spatial representation of data. Putting it simply, we argue that visualizing large amounts of InfoVis data can use encoding techniques which share the same continuity and multiscale principles as most classical spatial SciVis (or image processing) methods use. In turn, we show how this is possible by means of defining appropriate similarity metrics and encoding principles for InfoVis data. This leverages a wealth of data simplification, encoding, and perception principles, since long available for SciVis data, for the richer realm of InfoVis data. We demonstrate our image-based paradigm by examples covering the visualization of relational, multidimensional, and time-dependent InfoVis data.

Mini-bio: Prof. Alex Telea has obtained his PhD in data visualization at the University of Eindhoven in 2000, where he worked next as assistant professor in the same field until 2007. Since then, he is full professor of multiscale visual analytics at the University of Groningen, the Netherlands. His research interests are at the crossroads of multiscale image and shape processing and information visualization and visual analytics. He has published over 200 papers on the above topics, and is the author of the textbook ‘Data Visualization — Principles and Practice’ (CRC Press, 2008, 2014).

Seminar in partnership with INES 2.0: REFlex Water

September 27, 2017 3:39 pm

On September 29th, 2017, Ricardo Massa Ferreira Lima presented the REFlex Water engine.

Abstract: This project proposes the conception of a novel water management framework, called REFlex Water, that uses declarative business processes to specify the management policies and to control the actions of water managers. The main component of REFlex Water is the REFlex Rule Engine, which analyzes the rules of the declarative business process to identify inconsistencies or threats to the correct execution of the process. The engine controls the process execution, avoiding conflicts (deadlocks or livelocks) and the state space explosion observed in the existing engines. The REFlex Water framework integrates three main technologies: (1) IoT infrastructure for water management systems; (2) the REFlex Rule Engine for executing declarative processes; (3) CEP (Complex Event Process) Engine for interpreting great amount of sensors data in real time. Many works has addressed the first technology. This project innovates in integrating these three technologies into a single water management framework. We believe that declarative processes can provide the desired freedom the water managers need to perform their daily controlling activities, which relies mostly on their experience, but keeping the control over strict water policies. Likewise, the CEP engine brings the capacity for compiling signals from a complex network of sensors into a contextual water management information in real-time. Therefore, we expect to produce a complete solution for the efficient and safe management of complex water systems.

Mini-bio: Ricardo Massa Ferreira Lima is an assistant professor at Informatics Center of the Federal University of Pernambuco. Ricardo received his PhD degree in computer science from Federal University of Pernambuco, in 2000. He was a post-doc in the formal methods group at Chalmers University of Technology, Sweden, in 2001. Since 2010, Ricardo has been investigating the development of efficient and safe engines for executing declarative business processes as well as the application this technology in industrial scenarios. He supervised 2 PhD thesis and 3 MSc dissertation on these topics. Currently, four PhD students are working on themes related to the REFlex Water project.
