- Collaborative tools in higher education: the use of Wikis by industrial and mechanical engineering studentsPublication . Gaspar, Marcelo; Celorrio-Barragué, Luis; Pikkarainen, Ari; Glavan, Dan OvidiuContinuous technological advances keep challenging current and future engineers to anticipate and adapt to the new trends and paradigms that are expected to take place in a near future. One of such paradigms is the Industry 4.0 that encompasses the promise of a new industrial revolution based on the interconnectivity of people and systems to communicate, analyse and use information related to industrial processes. New challenges, as well as new opportunities, will rise in this digital landscape, demanding from future engineers the ability to adapt and grow in such ground-breaking environments. With such dynamic changes taking place in the current and future industries, engineering education has to adapt and prepare future graduates to work and function in these demanding environments. The set of skills envisaged to be held by future engineers is the ability to work and collaborate using digital means of participation as well as the ability to effectively use intercultural communicative skills. To this end, an exploratory study was conducted among different European Higher Education Engineering Schools to integrate a project with common aims and goals, resulting in various collaborative engineering activities that were designed to be carried out by undergraduate industrial and mechanical engineering students to further improve their learning outcomes and to acquire, or improve on, dedicated intercultural, communicative and colaborative skills. Following both quantitative and qualitative approaches, this study combined different types of data and methods of analysis in order to provide an exploratory account of the envisaged findings.
- Online learning environment tools in higher education : contributions to their integration in engineering coursesPublication . Gaspar, Marcelo; Pikkarainen, Ari; Celorrio-Barragué, Luis; Glavan, Dan OvidiuIn order to understand the potential of Online Learning Environment tools and resources in Engineering Education, a project on the use of dedicated educational strategies has been carried-out in various European Schools of Engineering to improve students’ engagement on different forms of participation and to enhance their learning outcomes. This study focuses on the use of Web 2.0 tools while teaching Manufacturing Processes to Industrial Engineering students of a Higher Education Portuguese Polytechnic Institute during a full semester. Cumulatively to students’ perceptions, data was collected and assessed to infer about two main research questions: “Are engineering students able to use efficiently online learning tools to enhance their autonomous learning process?” and “Can engineering students work collaboratively using online tools towards achieving common learning goals?”. Preliminary findings showed that students managed to efficiently use the proposed online collaborative learning tools during the course. However, students preferred the individual learning tools and processes to working and learning collaboratively from and with each other.
- Study on the influence of supplying compressed air channels and evicting channels on pneumatical oscillation systems for vibromooshingPublication . Glavan, Dan Ovidiu; Radu, I.; Babanatsas, T.; Babanatis Merce, R.M.; Kiss, I.; Gaspar, MarceloThe paper presents a pneumatic system with two oscillating masses. The system is composed of a cylinder (framework) with mass m1, which has a piston with mass m2 inside. The cylinder (framework system) has one supplying channel for compressed air and one evicting channel for each work chamber (left and right of the piston). Functionality of the piston position comparatively with the cylinder (framework) is possible through the supplying or evicting of compressed air. The variable force that keeps the movement depends on variation of the pressure that is changing depending on the piston position according to the cylinder (framework) and to the section form that is supplying and evicting channels with compressed air. The paper presents the physical model/pattern, the mathematical model/pattern (differential equations) and numerical solution of the differential equations in hypothesis with the section form of supplying and evicting channels with compressed air is rectangular (variation linear) or circular (variation nonlinear).
