About

The Laboratory for Advanced Collaboration (LAC) was founded in October 2003, as a joint venture between LES (Laboratório de Engenharia de Software, or Software Engineering Laboratory) and TecGraf — both from PUC-Rio — and, since then, LAC has had Prof. Markus Endler as its Head and Principal Investigator. Originally, it was conceived to conduct applied research and software development in distance learning and collaboration, virtual and augmented reality, as well as knowledge management and mobile and pervasive computing. Since 2005, LAC has turned its R&D focus on distributed, collaborative, context-aware and pervasive systems, with a strong emphasis on handling/supporting all sorts of mobility and wireless intermittent connectivity.

LAC’s main mission is to grow to become a center of excellence in scientific research, development, and innovation of practical distributed and mobile systems. We aim to enable and enhance the development of scalable applications that are socio-economic relevant and sustainable.

Projects

InterCity

The Future Internet will integrate large-scale systems constructed from the composition of thousands of distributed services, while interacting directly with the physical world via sensors and actuators, which compose the Internet of Things. This Future Internet will enable the realization of the Smart Cities vision, in which the urban infrastructure will be used to its fullest extent to offer a better quality of life for its citizens. Key to the ef?cient and effective realization of Smart Cities is the scienti?c and technological research covering the multiple layers that make up the Internet. This paper discusses the research challenges and initiatives related to Future Internet and Smart Cities in the scope of the InterSCity project. The challenges and initiatives are organized in three fronts: (1) Networking and High-Performance Distributed Computing; (2) Software Engineering for the Future Internet; and (3) Analysis and Mathematical Modeling for the Future Internet and Smart Cities. InterSCity aims at developing an integrated open-source platform containing all the major building blocks for the development of robust, integrated, sophisticated applications for the smart cities of the future. Index Terms—Smart Cities, Internet of Things, Future Internet, Big Data, Machine Learning, Mathematical Modeling.

ESMOCYP

As distributed IoT applications become larger and more complex, the pure processing of raw sensor and actuation data streams becomes impractical. Instead, data streams must be fused into tangible facts and these pieces of information must be combined with a background knowledge to infer new pieces of knowledge. And since many IoT applications require almost real-time reactivity to stimulus of the environment such information inference process has to de performed in a continuous, on-line manner. This paper proposes a new semantic model for data stream processing and real-time reasoning based on theconceptsofSemanticStreamandFactStream”,asa natural extensions of Complex Event Processing(CEP) and RDF (graph-based knowledge model). The main advantages of our approach are that: (a) it considers time as a key relation between pieces of information, (b) the processing of streams can be implemented using CEP and that (c) it is general enough to be applied to any Data Steam Management System (DSMS).

H 4.0

The Internet of Things (IoT) has numerous applications
in health care, from remote patient monitoring, smart
sensors, integration of smart medical devices, to improving and
optimizing the health care process. Some predictions say that
in the next few years there will be a boost of IoT adoption in
health care, both on the clinical side and the operational side.
Specifically for the complex management of hospital operations,
IoT will be able to solve well-known problems such as inefficient
coordination of health care teams, poor allocation of space, human
and material resources, and bad investment decisions. In this
line we believe that an up-to-date knowledge of the whereabouts
of patients, health care workers, and hospital equipment at all
times will transform the way modern hospitals operate and
are managed, leading to more efficient and effective businesses
based on statistical analysis and real-time alert mechanisms.
In this sense, we are developing Hospital 4.0, a distributed
IoT application that delivers real-time statistical information to
hospital administrators and the health care teams.Our solution
works by capturing signals sent by bluetooth beacons worn
by every patient and health professional (wristbands and ID
tags). We use them primarily for identifying the localization, the
timestamp of events and the co-located people. These gathered
data are used to generate statistics about resource usage and
notifications about emergency situations, which are displayed on
managerial dashboards.
