Students experimental competences are of most importance in engineering courses. However in post-Bologna courses, the number of contact hours and the actual extent of hands-on lab work were substantially reduced. Online resources usage (simulators and remote labs) has been growing up in the last decades, as more complex and versatile tools are being developed. Unfortunately, several of these usages reported in literature do not show the didactical backing that support these implementations. This work is a step forward, explaining how a teacher implemented a combination of online resources in order to develop experimental competences. The results show significant correlations between students' usage of these resources and their calculus competences and final achievements.

This paper discusses aspects of Information and Communications Technologies and how they have influenced our daily lives, especially our educational models. Despite the technological advances, the lack of interest of young people for science and technology careers increases and it is even more worsened by the fact that an extremely small number of schools have science and computer labs in Brazil. Moreover, some educational models have emerged in last decades contributing to teaching and learning process, and we discuss especially those which include remote experimentation and 3D virtual worlds, whose goal is to provide immersive learning environment with real experiments for students.

This work describes a Demo to be presented in the Demo Session at exp.at'15, related with an experiment that can be used either as hands-on or as a remote setup. In this way, after lab sessions students may use a totally familiar experiment any time they need to go back to the experimental topic. The electronics and the web server functionality are based on microcontrollers' capabilities and the sensing system is based on simple and homemade sensing devices. The prototype allows students to compare the mechanical properties of two different materials or offers a more complete investigation by analyzing and comparing results from distinct specimens - materials and/or beam geometries. It also permits to understand easily the concept of stiffness and its relation with Young Modulus and the specimen dimensions.

Coal has been for centuries a central energy source to fulfill industrial and domestic needs. Its large scale extraction produced huge amount of debris that were piled in the neighboring of the mines, quite often going into combustion triggered by events like forest fires or lightning. When in this state it can continue for years, releasing substantial emissions of toxic and greenhouse gases with recognized impact in the environment and, more serious in the short term, in the life quality of the populations located nearby. Continuous monitoring of combustion temperature and emission levels of certain gases opens the possibility to plan corrective actions to minimize their negative impact. Optical fiber technology is well-suited to this purpose and here it is described the main attributes of a fiber optic sensing system projected to gather data on distributed temperature and gas emission in these harsh environments.

Designed to visually illustrate the impact of internode communication on high performance computing, this model supercomputer integrates the major architectural components of modern heterogeneous machines. Using inexpensive compute nodes the machine supports major supercomputing development tools including OpenMP, MPI, and Nvidia's CUDA. These capabilities make it an accessible tool for illustrating parallel computing to a variety of classes.

The primary goal of this project is the development of a low cost track side system able to detect wheel defect impacts and to weigh the train in motion. Such a monitoring system may facilitate the infrastructure manager task of evaluating if the load applied to the tracks caused by passing trains, complies with the regulations. In this paper, the main technical aspects of this system are presented.

Teaching analog and digital electronic subjects is not a trivial task because is necessary to use opposite methodologies. The electronic design in the digital field is centered in the use of microprocessor and FPGA based circuits using high level programing/configuring languages. The counterpart analog design is traditionally based in the use of elementary components associated with macroblocks such operational amplifiers in order to built-up the wanted mission circuit. Some few components, as the FPAA, are analogically configurable in a similar manner already used with the FPGA. However the use of this kind of components is not straightforward once is necessary to acquire some concepts not taught in the traditionally analog electronic classes. The current work presents an innovative remote lab to support teaching of the FPAAs.

The paper describes two dynamic monitoring systems installed in civil engineering structures, a footbridge and a suspended stadium roof. These systems are used for characterization of environmental and operational effects and, in the limit, for the early detection of damage. Some examples of collected data and results are presented.
