uPATO applies social network analysis to team sports


on 06-05-2018

... Developed by a research team from IT in Covilhã, the uPATO - Ultimate Performance Analysis Tool is a software tool for social network analysis applied to team sports. There are other software tools available but normally they are not free, or they do not have all the metrics need. For example, the metrics that used the geodesic distance sometimes are not available in some tools.

To do a social network analysis it is necessary a representation of the network (i.e. a graph or a digraph). Thus, a first module was developed to allow codifying the network, which in the case of team sports is given by the sequences of interactions between teammates. This module, for example, allows the user to codify a sequence of passes during a match and to generate an adjacency matrix, which represents the weighted digraph.

A second module of the tool involved the programming of all metrics available for network analysis applied to team sports based on adjacency matrix. The metrics were codified for all network possibilities, i.e. for graphs and digraphs, weighted or not. This means that uPATO tool can be applied for social network analysis in team sports, but also for any network that can be represented by an adjacency matrix (e.g., a computer network or a telecommunication network, etc.). Thus, the metrics are divided into three types: individual metrics, sub-group metrics, and team metrics. These make possible to compute different network measures, providing scores to classify the collective and individual performance over the network.

It also does the graphical representation of the graph or digraph (weighted or not) allowing an easier understanding of which nodes in the network (i.e. the players in case of team sports) are more important.

In the future, the uPATO tool will have an additional module for geolocation data processing. Currently, some teams use GPS devices to have the position of the players during the match (e.g., FieldWiz and TraXports formats will be supported). Thus, uPATO will have a set of metrics based on geolocation data of players. This new functionality extends the uPATO capacities for team sports analysis but also for other activities where GPS data is available. However, it does not consider yet the possibility of the ball with a GPS device.

Project BEACON brings high-speed internet to flight passengers


on 02-05-2018

... Who among us has never wished for a faster internet connection during a flight? IT is part of the international consortium working on the European R&D project “Beacon”, that may have found the solution for this problem. Based on a flexible photonic architecture - patented by IT -, this project prepared a new generation of telecommunications satellites, that stands out for their greater capacity of data transmission. The photonic technology also allows reducing the energy consumption, weight and launch cost.

This research emerges from a context where the demand for high-speed broadband bandwidth has been exponentially increasing, a process that requires the development of satellites that guarantee an even greater high-speed connectivity and a wide coverage. However, currently - and despite operators pushing for a 10x increase in broadband capacity - weight, size and power limitations still represent significant challenges.

The international consortium that worked in project Beacon – recently concluded - includes companies from the United Kingdom (Airbus Defense and Space, Gooch & Housego and aXenic), Germany (IHP GmbH) and Poland (INPhotech). In Portugal, the participation was assured by IT in Aveiro and the startup Watgrid
