This paper describes experiments with a game device that was used for early detection of delays in motor skill development in primary school children. Children play a game by bi-manual manipulation of the device which continuously collects ac- celerometer data and game state data. Features of the data are used to discriminate between normal children and children with delays. This study focused on the feature selection. Three features were compared: mean squared jerk (time domain); power spectral entropy (fourier domain) and cosine similarity measure (quality of game play). The discriminatory power of the features was tested in an experiment where 28 children played games of different levels of difficulty. The results show that jerk and cosine similarity have reasonable discriminatory power to detect fine-grained motor skill development delays especially when taking the game level into account. Duration of a game level needs to be at least 30 seconds in order to achieve good classification results.
Mexico City airport is located close to the center ofthe city and is Mexico’s busiest airport which is consideredcongested. One of the consequences of airport congestion areflight delays which in turn decrease costumer’s satisfaction. Airtraffic control has been using a ground delay program as a toolfor alleviating the congestion problems, particularly in the mostcongested slots of the airport. This paper uses a model-basedapproach for analyzing the effectiveness of the ground delayprogram and rules. The results show that however the rulesapplied seem efficient, there is still room for improvement inorder to make the traffic management more efficient.

Over the last couple of years there is a growing interest in the role of the bicycle in Western urban transport systems as an alternative to car use. Cycling not only has positive environmental impacts, but also positive health effects through increased physical activity. From the observation of the Urban Intelligence team that cycling data and information was limited, we have started the development of cycleprint. Cycleprint stands for Cycle Policy Renewal and INnovation by means of tracking Technology with the objective to enable more customer friendly cycle policy.The initial objective of Cycleprint was to translate GPS data into policy relevant insights to enable customer friendly cycle policy. The online toolkit what Cycleprint has become, answers the questions about:-route choice-speeds-delays at intersections -intensities Because of the success of Cycleprint in the Netherlands the range of features is still under development. As a result of the development of Cycleprint the Dutch organized the fietstelweek. In addition to Cycleprint the Urban Intelligence team developed the cyclescan to explore the effects of cycle network enhancement. The project is developed in direct collaboration with the Provincie Noord-Brabant and Metropoolregio Eindhoven to fulfill the ambition to become cycling region of the Netherlands in 2020.
Positive Energy Districts (PEDs) can play an important part in the energy transition by providing a year-round net positive energy balance in urban areas. In creating PEDs, new challenges emerge for decision-makers in government, businesses and for the public. This proposal aims to provide replicable strategies for improving the process of creating PEDs with a particular emphasis on stakeholder engagement, and to create replicable innovative business models for flexible energy production, consumption and storage. The project will involve stakeholders from different backgrounds by collaborating with the province, municipalities, network operators, housing associations, businesses and academia to ensure covering all necessary interests and mobilise support for the PED agenda. Two demo sites are part of the consortium to implement the lessons learnt and to bring new insights from practice to the findings of the project work packages. These are 1), Zwette VI, part of the city of Leeuwarden (NL), where local electricity congestion causes delays in building homes and small industries. And 2) Aalborg East (DK), a mixed-use neighbourhood with well-established partnerships between local stakeholders, seeking to implement green energy solutions with ambitions of moving towards net-zero emissions.
Air-to-Water (A2W) systems are innovative technologies which make possible to supply drinking water to regions without any nearby surface or ground water source. Such systems use green energy (solar, wind) to condense air humidity and provide fresh water in rather remote locations. As water production is area dependent, they operate at relatively small fluxes (few cubic meters per day, per unit), which makes them especially suitable for small isolated communities that are not supplied by municipal water supply services. Even though they have reached quite high technology redness level (TRL), in-situ, real scale, tests are still required to optimize energy performance and evaluate production at very specific meteorological conditions. In this project we propose an in-situ evaluation of the performance of a real scale A2W system produced by a Dutch company (Dutch Rain Maker, model AW-25) in the semi-arid region of Northeast Brazil. The cooperation with a HBO institute (Water Technology lectoraat, NHL Stenden) will provide the necessary analytical and technical support as well as extra expertise to conduct the tests. The project uses the opportunity given by the state government of Ceará State which built an infra-structure to provide space for in-situ tests for experts and companies who would like to test water technology solutions for arid regions. Finally, it is also intended to help establishing partnerships between European SME and Brazilian end users, i.e. municipalities of the Ceará state and small agriculture companies in the region.
