In the last sunday (09/02/18), the HackMobility2018 event took place in downtown São Paulo.
The hack day event hosted 21 participants, all women, and aimed to analyze data related to urban mobility in São Paulo to propose solutions that contribute to a more accessible city for pedestrians and cyclists. For this purpose, the participants had access to several datasets of city departments, such as the Health Secretariat, the Traffic Engineering Company (CET), São Paulo Transportation department (SPTrans), among others. These datasets include information such as traffic accidents, traffic tickets, hospital care and deaths.
The event was conceived and organized by USPCodeLab , the Ciclocidade and InterSCity, and was supported by Yellow . The HackMobility2018 happened in the São Paulo’s Laboratory of Innovation in Mobility (MobiLab).
During the 10 hours of the event, the participants, organized into 5 teams, developed their ideas and solutions for mobility. Most of the teams focused on public safety issues, which shows that this is one of the main concerns related to mobility in São Paulo, especially for women.
At the end of the event, the teams presented their proposals and were evaluated by a judging committee composed of Ana Carolina Nunes, director of Cidadeapé, Haydee Svab, researcher in Urban Mobility and Graziela Tonin, professor and researcher in Software Engineering at the Federal University of the Border South.
The winning proposal was the Friend Tip app, proposed by Iara Pereira, Jéssica Rocha, Lais Aguiar, Michelle Tanaka and Nataly Gonçalves. Friend Tip traces safer routes for cyclists. In addition, the app identifies users who make similar routes to suggest friends for group travels. Friend Tip uses data of accidents in São Paulo and the São Paulo cycling routes to identify the most dangerous routes. The winning team members received R$ 200.00 in credits for using Yellow bikes, while the other participants received credits of R$ 50.00 each one.

Abstract: In Brazil and around the world, there are millions of people with various deficiencies. Besides, an aging population is a worldwide tendency, which implies a growing number of seniors in society, with diverse kinds of functional and cognitive limitations. Finally, women in the final stages of pregnancy, small children, or people without deficiencies but with temporary limitations, all benefit from Accessibility. But what is Accessibility? In this presentation, we explore this subject and investigate how Information Technology may be used to help people study, work, or simply leave their homes.

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.
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.

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.

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).
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.

On August 25th, 2017, Eduardo Santana presented the first version of InterSCSimulator, a Smart Cities open code, extensible and large scale simulator. The seminar may be watched on YouTube
Resumo: Um simulador de Cidades Inteligentes necessitará representar um grande número de atores, como carros, edifícios e linhas de transmissão de energia. Nessa versão já é possível simular cenários de trânsito, inclusive com transporte público, com milhões de atores em um mapa real de uma grande cidade.
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.
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.
