Seminar in partnership with INES 2.0: Energy Consumption on Android – A comparison of different approaches of development

April 25, 2018 6:54 pm
When: Friday, May 4th, 2018, 3:00 PM.

Speaker: Wellington Oliveira (CIN/UFPE).

Abstract: Mobile devices have become ubiquitous in the recent years, but the complaints about energy consumption are almost universal. On Android, the developer can choose among several different approaches to develop an app. This presentation shows our investigation on the impact of some of the most popular development approaches on the energy consumption of Android apps. Our study used a testbed of 33 different benchmarks and 4 applications on 5 different devices to compare the energy efficiency and performance of the most commonly used approaches to develop apps on Android: Java, JavaScript, and C/C++. In our experiments, Javascript was more energy-efficient in 75% of all benchmarks, while their Java counterparts consume up to 36.27x more energy. On the other hand, both Java and C++ outperformed JavaScript in most of the benchmarks. Since most Android apps are written solely in Java, the results of this study indicate that leveraging a combination of approaches may lead to non-negligible improvements in energy-efficiency and performance.

Short-bio: Wellington de Oliveira Júnior is a PhD student at the Federal University of Pernambuco, being advised by Prof. Fernando Castor. He is member of SPG (Software Productivity Group) and is currently researching in the field of green computing. More specifically, on ways to optimize the energy efficiency of mobile devices through modifications in the application source code. His ongoing researches are investigating what impact different collections and concurrency abstractions have on energy consumption of an Android app.




Seminar in partnership with INES 2.0: Social Housing and Sprawl – The Minha Casa Minha Vida Case

April 20, 2018 3:17 pm

When: Monday, May 14th, 2018, 10:00 AM.

Where: Auditório do CCSL-IME/USP.

Speaker: Ciro Biderman (FGV-SP)

Abstract: We analyze the impacts on the urban form of a large Brazilian public housing program—Programa Minha Casa Minha Vida (PMCMV). Our aim in this paper is to determine whether the program impacts urban sprawl and its trend.  We analyze 18 metropolitan areas using satellite images and other datasets to compare municipalities where the program was more intense with municipalities where the program produces housing below the median. First, we compare the urban footprint in 2005 and 2015. Second, we compare the trend from 1995 to 2005 with that from 2005 to 2015. The conclusion is that the program itself has no significant impact on urban sprawl. However, the number of units built does have an impact on the spatial pattern of the urban footprint. Cities were infilling faster before the program was implemented. The program is currently under revision and we suggest that it can be improved by shifting the incentives to converge to more centralized development of the land leading to more compact cities.


The Plug & Network paradigm: a new way of designing networks

March 22, 2018 5:53 pm

When: Friday, March 23th, 2018, 9:00 AM.

Where: Sala H-312C, GTA/UFRJ.

The objective of this presentation is to introduce the new paradigm that will be used from 2020:  the “Plug &Network” concept. This concept allows to derive new network architectures ranging from a completely centralized architecture to a fully distributed solution. We will examine the pros and cons of these different architectures to try to imagine architectures that should be deployed in the 2020s.

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.

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.

Seminar in partnership with INES 2.0: O ecossistema da plataforma InterSCity

June 28, 2017 4:05 pm

On June 26th, 2017, InterSCity and INES 2.0 had another issue of their periodic joint seminar when Arthur Del Esposte discussed the InterSCity platform. The seminar was transmitted in realtime and may be watched on YouTube.

Resumo: Apesar dos vários avanços nas tecnologias de middleware para suporte às Cidades Inteligentes do futuro, ainda não existem plataformas amplamente aceitas. A maioria das soluções existentes não oferece a flexibilidade necessária para serem compartilhadas entre as cidades. Além disso, o vasto uso e o desenvolvimento de software proprietário levam a problemas de interoperabilidade e limitam a colaboração entre os grupos de P&D. Neste seminário, apresentaremos as principais linhas de pesquisa atualmente desenvolvidas pelo grupo do IME/USP no contexto do INCT da Internet do Futuro para Cidades Inteligentes. Mais espeficamente, apresentaremos a Plataforma InterSCity, uma plataforma de código aberto cujo objetivo é facilitar o desenvolvimento de pesquisas, aplicações e serviços sofisticados para Cidades Inteligentes. Dentre outros tópicos, iremos abordar a sua arquitetura de microsserviços, aplicações e sua integração com o Simulador de Cidades Inteligentes também desenvolvido no IME-USP.

Presentation at USP: Tecnologias de participação: introdução aos requisitos de informação para políticas públicas

June 28, 2017 3:59 pm

On May 15th, 2017, André Leirner has offered a presentation at USP on how to leverage citizen participation in public administration.

Resumo: Cidades inteligentes pressupõe serviços públicos efetivos e responsivos ás demandas sociais. Mas como colher essas informações? Como garantir que um ambiente inteligente seja assistivo invés de manipulativo? Como identificar demandas prioritárias especificas invés de orientar-se pela demanda majoritária? Para investigar essas questões vamos observar um caso crítico, que é o da representação no contexto democrático. Vamos conhecer os dilemas da representação democrática, o ciclo das politicas publicas e examinar quatro modelos concretos de uso da tecnologia para tomada de decisão nesse contexto. Dentre esses modelos, observaremos com maior cuidado um modelo desenvolvido a partir das atividades do LAB-XP, do IME, já operacional.

Mini-bio: Andre Leirner é arquiteto pela FAU-USP, possui mestrado em Design Experimental pela Architectural Association de Londres e mestrado em Administração Pública e Governo pela FGV-EAESP. É atualmente pesquisador do Núcleo de Democracia e Ação Coletiva do CEBRAP, Centro Brasileiro de Análise e Planejamento e professor convidado da Oficina Municipal. Desempenhou também atividades de pesquisa e desenvolvimento na disciplina LAB-XP do IME-USP.
