Self-powered IoT Device based on Energy Harvesting for Remote Applications
2018
In this paper, we present the design and prototype implementation of self-powered Internet of Things (IoT) device based on energy harvesting from a small solar panel of size 63mm x 63mm and 0.36W for remote applications. These IoT devices can be deployed in remote places within the range of a gateway. A complete proof of concept IoT device based on ambient energy harvesting is designed, prototyped and tested with super capacitors and Lithium cells in star topology. Based on the measurements, the IoT device can potentially last for one year with 55 seconds transmission interval with the fully charged 120mAh coin cell battery. On the other hand, a fully charged single 5F supercapacitor lasts …
Lo spazio logico della metafisica
2018
Partendo dal rapporto con il "campo dei concetti" descritto da Kant nella "Critica del giudizio", si riflette sul campo della metafisica individuato da Nicolaci come uno spazio, proprio della filosofia nel suo ruolo eminentemente critico,e come un compito specifico della metafisica
The Raising Factor, That Great Unknown. A Guided Activity for Undergraduate Students
2020
In the first years of their economics degree programs, students will face many problems successfully dealing with a range of subjects with quantitative content. Specifically, in the field of statistics, difficulties to reach some basic academic achievements have been observed. Hence, a continuing challenge for statistics teachers is how to make this subject more appealing for students through the design and implementation of new teaching methodologies. The latter tend to follow two main approaches. On the one hand, it is useful for the learning process to propose practical activities that can connect theoretical concepts with real applications in the economic context. On the other hand, we …
Barriers to women entrepreneurship. Different methods, different results?
2016
Building on research by Akehurst et al. (Serv Ind J 32:2489-2505, 2012), this study analysed internal and external factors in women entrepreneurship and linked these factors to the barriers that women face when starting businesses. To do so, two contrasting statistical techniques were used: PLS and QCA. After analysing results from each of these techniques, we observed that family duties and difficulties in obtaining financing (both internal and external) were the main factors related to barriers faced by women entrepreneurs.
Dynamics of the Selkov oscillator.
2018
A classical example of a mathematical model for oscillations in a biological system is the Selkov oscillator, which is a simple description of glycolysis. It is a system of two ordinary differential equations which, when expressed in dimensionless variables, depends on two parameters. Surprisingly it appears that no complete rigorous analysis of the dynamics of this model has ever been given. In this paper several properties of the dynamics of solutions of the model are established. With a view to studying unbounded solutions a thorough analysis of the Poincar\'e compactification of the system is given. It is proved that for any values of the parameters there are solutions which tend to inf…

Does usable research face higher obstacles within the academy?
2018
The recognition of academic research as a potential source of economic growth and social welfare has attracted the attention of both policy-makers and academics over the past decades. But emphasising the impact of research brings a new set of tensions to scientific governance processes, and raises the risk that academics who engage more with users be hindered in pursuing their research activities. In this paper, we seek to understand whether researchers that meaningfully engage with societal users in their research micro-practices face additional obstacles in their research, whether in terms of the acceptance of that research by academic communities and the absorption of that knowledge by u…
Teoría de la educación : revista interuniversitaria
2012
Family, as the first structure that receives minor, owns a big importance with regard to other educational spaces during the integral development of children. In it and through it decisive and persistent transmissions for the human being that come to realize through some parental concretes styles, take place. In this article we analyzed two approaches, from our perspective, valid for explaining the educative styles nowadays: the model of joint construction and the interactive model, with typologies and researches that have not had quite echo in other publications and those we think are outstanding to open new lines of research. Revised scientific reports are brought by Pedagogy, Psychology …
Force Concept Inventory-based multiple-choice test for investigating students’ representational consistency
2010
This study investigates students' ability to interpret multiple representations consistently (i.e., representational consistency) in the context of the force concept. For this purpose we developed the Representational Variant of the Force Concept Inventory (R-FCI), which makes use of nine items from the 1995 version of the Force Concept Inventory (FCI). These original FCI items were redesigned using various representations (such as motion map, vectorial and graphical), yielding 27 multiple-choice items concerning four central concepts underpinning the force concept: Newton's first, second, and third laws, and gravitation. We provide some evidence for the validity and reliability of the R-FC…
Beasts, Human Beings, or Gods? Human Subjectivity in Medieval Political Philosophy
2016
Human beings are not only self-conscious minds but embodied and social beings, whose subjectivity is conditioned by their social surroundings. From this point of view, it is natural to suppose that the development and existence of a subject that is distinctively human requires contact with other people. The present contribution discusses medieval ideas concerning the intersubjective constitution of human being by looking at the medieval reception of two ideas, which Aristotle presents at the beginning of his Politics: (1) human beings are political animals by nature, which means that those who live outside of political communities due to their nature are either deficient or above humanity –…
