This paper describes several experiments performed by our research group to show the use of smartphones in physics teaching. We document our work on the development of apps for smartphones and on how to use recorded sensor data. As a final result, some interesting outcomes are obtained from the surveys conducted on the students about the use of these(More)
The use of mobile technologies is reshaping how we teach and learn. In this paper we describe our research on the use of these technologies to teach physics. On the one hand we develop mobile applications to complement the traditional learning and to help students learn anytime and anywhere. The use of this applications has proved to have very positive(More)
The Raven's Progressive Matrices (RPM) test is a commonly used test of intelligence. The literature suggests a variety of problem-solving methods for addressing RPM problems. For a graduate-level artificial intelligence class in Fall 2014, we asked students to develop intelligent agents that could address 123 RPM-inspired problems, essentially crowdsourcing(More)
In vitro chromosome doubling techniques have been used to produce polyploids in several species, including table grapes, but limited research in this field has been performed using winegrapes. An efficient procedure was established to induce tetraploid grapevine plants by colchicine treatment of embryogenic cell aggregates (ECAs) grown in winegrape cultivar(More)
INTRODUCTION Facial emotional expression constitutes a basic guide in the social interaction and, thus, the alterations in its expression or recognition imply an important limitation for the communication. On the other hand, cognitive impairment and the presence of depressive symptoms, which are commonly found in patients with multiple sclerosis, it is(More)
Physics is a subject that for a complete teaching and learning requires both theoretical discussions and practical experimentation. In this work we describe how mobile applications can turn smartphones into versatile measurement devices for broad fields of physics. Different physics experiments performed using our own developed applications, both in the(More)
Embryogenic suspension cultures are suitable for EMS mutagenesis in grapevine, and HRM prescreening of EMS-treated somatic embryo clusters allows rapid detection of point mutations before plant regeneration. Somatic embryogenesis is an excellent system for induced mutagenesis and clonal propagation in woody plants. Our work was focused on establishing a(More)
