A cosmic ray muon detection system is proposed for stability monitoring in the field of civil engineering, in particular for the static monitoring of historical buildings, where conservation constraints are severe and the time evolution of the deformation phenomena under study may be of the order of months or years. The stability monitoring of the wooden vaulted roof of the Palazzo della Loggia, located in the town of Brescia, Italy, has been considered as a case study. The feasibility, as well as the performance and limitations of a stability monitoring system based on cosmic ray tracking have been studied by Monte Carlo simulations. A study of possible systematic uncertainties is presented along with a realistic design for the construction of a measurement system prototype.
In engineering colleges, first-year students come from different kinds of high school and have different technical backgrounds. In engineering graphics courses, the weaker students are the ones entering with a lower technical background. Such students are less motivated and have generally difficulties in keeping high their attention level during the lessons. In this study, the use of a webcomics structured in graphic novels was experimented as a motivational support in an engineering graphics course. Sixty nine students of a class taught by using webcomics as support and 47 students of a class taught traditionally were classified according to the kind of their high school of provenience: technical; scientific; non-technical and non-scientific. The findings showed that in the class where webcomics were used, students from non-technical and non-scientific high school scored a higher level of attention compared to others. The teacher who used the webcomics commented it an effective tool to encourage and stimulate weaker learners to actively participate to the lessons and the majority of students agreed such tool was stimulating. At the same time, some students considered the webcomics representation of engineering graphics topics as too far from the reality. It is concluded that the use of webcomics structured in graphic novels is a proficient way to better motivate weaker students to arouse and keep their attention at a high level during engineering graphics lessons.

This work presents the development of an integrated framework and related tools for innovation and improvement in the teaching of Technical Drawing. This framework is based on the “Technical Drawing Evaluation Grid—TDEG.” This grid is currently used, by the authors, for the definition and the development of different kinds of tools for supporting both teaching and learning and for the evaluation of Technical Drawing and engineering graphics topics knowledge in general. In particular, this paper focuses on the problems related to knowledge evaluation and assessment of Technical Drawing using online tests. Then, the LaMoo project which is a tool under development for the structured construction of questions for online tests in Moodle environment is presented.
