The Model Matching Problem for Max-Plus Linear Systems: a Geometric Approach

Linear systems over the max-plus algebra provide a suitable formalism to model discrete event systems where synchronization, without competition, is involved. In this paper, we consider a formulation of the model matching problem for systems of such class, in which the output of a given system, called the plant, is forced, by a suitable input, to track exactly that of a given model. A necessary and sufficient condition for its solvability is obtained by making a suitable use of geometric methods in the framework of systems over the max-plus algebra

Attention Capture by Direct Gaze is Robust to Context and Task Demands

The final publication is available at Springer via https://dx.doi.org/10.1007/s10919-011-0128-z.Eye-tracking was used to investigate whether gaze direction would influence the visual scanning of faces, when presented in the context of a full character, in different social settings, and with different task demands. Participants viewed individual computer agents against either a blank background or a bar scene setting, during both a free-viewing task and an attractiveness rating task for each character. Faces with a direct gaze were viewed longer than faces with an averted gaze regardless of body context, social settings, and task demands. Additionally, participants evaluated characters with a direct gaze as more attractive than characters with an averted gaze. These results, obtained with pictures of computer agents rather than real people, suggest that direct gaze is a powerful attention grabbing stimulus that is robust to background context or task demands.103305-1/Canadian Institutes of Health Research89822-1/Canadian Institutes of Health Research103305-1/PHS HHS/United States89822-1/PHS HHS/United State

Learning robotics: a review

Purpose of Review: With the growing interest for STEM/STEAM, new robotic platforms are being created with different characteristics, extras and options. There are so many diverse solutions, that it is difficult for a teacher/student to choose the ideal one. This paper intends to provide an analysis to the most common robotic platforms existent on the market. The same is happening regarding robotic events all around the world, with objectives so distinctive, and with complexity from easy to very difficult. This paper also describes some of those events which occur in many countries. Recent Findings: As the literature is showing, there has been a visible effort from schools and educators to teach robotics from very young ages, not only because robotics is the future, but also as a tool to teach STEM/STEAM areas. But as time progresses, the options for the right platforms also evolves making difficult to choose among them. Some authors opt to first choose a robotic platform and carry on from there. Others choose first a development environment and then look for which robots can be programmed from it. Summary: An actual review on learning robotics is here presented, firstly showing some literature background on history and trends of robotic platforms used in education in general, the different development environments for robotics and finishing on competitions and events. A comprehensive characterization list of robotic platforms along with robotic competitions and events is also shown

Adaptive control for non-linear test bench dynamometer systems

Engine-in-the-loop (EiL) setups need accurate and fast dynamometer control systems. An accurate test bench model is a demand approach that also offers a significant potential to provide an excellent reproducibility of test runs. The paper presents a novel EiL approach for ASM (Asynchronous Machine) automotive test bench applications. The non-linearity of an ASM is treated with advanced control techniques defining specific parameters to control and model the machine. The integration of adaptive control on the vehicle under test strongly increases the accuracy of each test. The results demonstrate the improved performance obtained with EiL approach and the significant benefits regarding adaptive control

Escape from Tolentino During an Earthquake Saving as Many Lives and Cultural Objects as You Can

In the last five years, the Italian Ministry of Education has placed its focus on digital skills, recognizing them as fundamental and indispensable for the growth of future citizens in the information age. It has thus backed projects aimed at developing computational thinking and digital creativity at school. One of the highest-funded of such projects is “Più vicini al nostro territorio—Valorizziamo i monumenti di Tolentino … giocando con Scratch e App Inventor” (Closer to our territory—appreciating the value of Tolentino’s monuments … while playing on Scratch and App Inventor). In this paper we describe this project, its vertical path, and the results of the first activities, which have already taken place in a primary school. These results show the progression of the skills and competences defined in the National Operational Programme document “For school 2014–2020” (Axis I Education, Objective 10.2, Improving students’ key competences), and those set out in the National Plan for Digital Education

GPS data integration to reduce driving emissions of MHEVs in real operating conditions

Increasingly emission reduction requests and environmental pollution cut require improved optimization of current transportations. Control strategies and latest vehicles technologies developed in the automotive industry must be optimized, taking into account more information is possible from cars sensors to save energy and reduce emissions. The paper presents a possible strategy for reducing emissions with integration of GPS data in a Mild Hybrid Electric Vehicle simulator. In this study, real GPS data are evaluated to improve the system and introduce real environmental conditions in the system. The data obtained are analysed selectively in the paper. This paper is aimed to investigate the impact of real conditions on fuel consumption. Through theoretical analysis, the conclusion will be drawn that GPS technology is attractive to reduction of emissions
