In higher education, as in other levels of education, there are different teaching strategies (expository with interaction, use of technological resources, problem-solving, project-based, game-based, etc.) in which success always depends on the involvement of students, the commitment of teachers, and much of the interaction between them in the task of contributing together so that the teaching-learning process is as fruitful as possible for the student. This task is not always easy for the teacher, because they have to divide the teaching activity with other tasks, because the number of students in charge is large, because each student has different characteristics and competences, etc. Correctly monitoring the different learning speeds of each student requires frequent collection of appropriate information, metrics and respective analysis. In this context, continuous assessment is a good approach, but it requires tools that, without consuming too much useful class time, allow the teacher to collect information about the perception and retention of knowledge by the students, and through the analysis of this information, allows them to adapt the strategies in order to reinforce the matters in which there are more difficulties or to increase the teaching pace in the case of matters already assimilated. It is also important that the collection of this information during class is done in a non-intrusive and in a motivating way, exploring the means currently available to students, namely in terms of technology. With the tool presented in this paper, the teacher has at their disposal the means to check if at a given moment their students are assimilating the material taught, what percentage of them are having learning difficulties, if in a period of time they have evolved in terms of knowledge acquired, if students still remember what they have learned since a past period, etc. In this way, the syllabus planning and execution of a given subject can be improved in terms of focus and time slots for explanation of certain topics, reinforcement of exercises, evaluation emphasis, etc. With this tool, it is possible to simplify the sampling of the learning progress, and thus adopt strategies that bring gains in agility to the teaching-learning process.

The use of rubber aggregates, steel and textile fibres recycled from tires in concrete is a solution that it is being studied by several authors around the world. A few works have been carried out at room temperature but very scarce at high temperatures. This paper presents the results of a research with the aim to evaluate the behaviour at high temperatures of a concrete made with different amounts of recycled textile and steel fibres from tires. The study considered five concrete compositions, with the same water/cement ratio (W/C=0.43), differing only in the type and quantity of fibers incorporated in the mixture. Thus, a reference composition (0% fiber), two compositions with 30 and 70kg/m3 of steel fibers and a composition with 2 and 4kg/m3 of textile fibers from tires were tested. The concrete was tested for a load level of 0.5fcd and different maximum temperature levels (20, 300, 500 and 700ºC).

This paper presents the performance evaluation of a wireless sensor mesh network, for monitoring temperature and humidity in horticultural products when transported in truck galleys. For this purpose a software solution was proposed using ESP8266 devices powered by batteries. The mesh network was managed by the painlessMesh library. The proposed solution aims to minimize the energy consumption of the sensor nodes. The validation of the solution was performed in an area simulating a galley of a truck, where five sensor nodes and a root node were distributed. The tests were developed considering four different models involving variations in messages delivery confirmation, number of attempts until successful delivery and duty cycle duration of the nodes. The performance evaluation of the solution aimed to determine, connectivity rate, sending rate after connection and delivery rates of the first and second attempts. The results obtained show that the message delivery confirmation does not bring added value to the solution, contributing only to increase energy consumption. The use of synchronous duty cycles also showed worse results than the asynchronous use. These results allow the creation of a knowledge base for the use of this solution in a real context.
Every technical novelty brought new hopes for education. Nowadays we are witnessing and we also feel a huge pressure to use e-Learning platforms. It is consensual that e-learning can introduce different ways to teach and learn because new approaches can be introduced within the educational context. But e-learning can only be just a new and different technological device… Virtual communities are important in this new educational environment because it is very easy to exchange information and data. However, its growth and maintenance will require from teachers and students new ways of working. It is possible to argue that e-learning may promote real «knowledge transaction» among the members of the virtual communities? This paper aims to reflect and discuss the main advantages, difficulties and limitations of e-learning in order to promote and adequate an efficient use under a strong pedagogical approach.
