Directed graphical models such as Bayesian nets are often used to implement intelligent tutoring systems able to interact in real-time with learners in a purely automatic way. When coping with such models, keeping a bound on the number of parameters might be important for multiple reasons. First, as these models are typically based on expert knowle...

We introduce ADAPQUEST, a software tool written in Java for the development of adaptive questionnaires based on Bayesian networks. Adaptiveness is intended here as the dynamical choice of the question sequence on the basis of an evolving model of the skill level of the test taker. Bayesian networks offer a flexible and highly interpretable framewor...

A test is adaptive when the sequence and number of questions is dynamically tuned on the basis of the estimated skills of the taker. Graphical models, such as Bayesian networks, are used for adaptive tests as they allow to model the uncertainty about the questions and the skills in an explainable fashion, especially when coping with multiple skills...

Nowadays, most people carry around a powerful smartphone which is well suited to constantly monitor the location and sometimes even the activity of its user. This makes tracking prevalent and leads to a large number of projects concerned with trajectory data. One area of particular interest is transport and mobility, where data is important for urb...

Nowadays, most people own a smartphone which is well suited to constantly record the movement of its user. One use of the gathered mobility data is to provide users with feedback and suggestions for personal behavior change. Such eco-feedback on mobility patterns may stimulate users to adopt more energy-efficient mobility choices. In this paper, we...

EDM (Electric Discharge Machining) drilling is a widely used machining process to create holes in hard to machine materials, such as cooling holes in turbine blades and diesel injectors. In such production applications where a large number of holes are machined, productivity is of high importance, which can be achieved through process optimisation....

GoEco! is one of several smartphone applications that perform automatic mobility tracking. In contrast to many others, it uses the tracked movement data to compute possible behavioral improvements of its users, and provides this assessment as eco-feedback in various forms. These include booklets detailing user journeys and possible alternatives in...

Conference Paper
An adaptive test is a computer-based testing technique which adjusts the sequence of questions on the basis of the estimated ability level of the test taker. We suggest the use of credal networks, a generalization of Bayesian networks based on sets of probability mass functions, to implement adaptive tests exploiting the knowledge of the test devel...

The project GoEco! takes advantage of the wide availability of smartphones, in order to overcome the traditional awareness-raising approach used to foster sustainable mobility and exploit eco-feedback, social norms and peer pressure elements in an ICT-based motivation system. In particular, it uses a smartphone app to analyze how we can encourage p...
Conference Paper

The diffusion of electric vehicles is one of the most promising opportunities to reduce dependency on fossil fuels and to pave the way for the transition to a more sustainable mobility. However, apart for the main barrier still represented by the purchase cost, the adoption of electric vehicles is still hindered by other barriers, such as autonomy,...

... Trackintel 8 is a library for the analysis of spatio-temporal tracking data with a focus on human mobility. The core of Trackintel is the hierarchical data model for movement data [4] that is widely adopted in GIScience [9], transport planning [13] and related fields [45]. We provide easy-to-use and efficient functionalities for the full life-cycle of human mobility data analysis, including import and export of tracking data of various types (e.g, GPS trackpoints, location-based social network (LBSN) check-ins, call detail records), data model generation and preprocessing, analysis, and visualization. ...
... The second type noticed as an evolution of ACS in WEDM use digital control of stochastic model reference or fuzzy control strategy [21]. With stochastic approach Maradia, Benavoli [93] shown that it offers a quick response due to control parameters adjusted online with the process. However, as pointed by Yan and Liao [21], difficulties in predicting transient behaviour and machining stability are the main drawbacks of this technic. ...
... This parameter, however, greatly depends on the chosen mode of transport, e.g., for walking activities the tracking resolution is much higher (the app saves battery by only recording GPS trackpoints if the accelerometer patterns change, which frequently happens while walking). In addition, locations where users spent longer than a certain amount of time were automatically identified as staypoints [59]. As the GoEco! ...
... Overall, sixteen families, for a total of twenty-seven users, took part in the living lab; seven of these families were EAs, while nine of them were MCs. Details regarding their socio-economic conditions were provided in Cellina et al. (2015). They all lived in the Lugano area: a conurbation of around 135'000 inhabitants characterized by heavy urban sprawl, where people has a strong tendency to use the private car for the majority of their trips (OFS-ARE (2012)). ...
