     Global food demand is rising exponentially as the population is increasing.  Protected farming is becoming increasingly popular among the farming communities for fast growing vine crops round the year.  Consideration of crop growing parameters while designing and maintaining a protected farm is very important for optimal crop growth and profit.  Many farmers does not consider all the crop growing parameters and does not know the importance of all factors in the optimal crop growth.  In this paper, an attempt has been made to prioritize 12 crops growing parameters using fuzzy approach.  12 crop growing parameters were selected from the literature and scored by four different evaluation methods viz., food consumer importance, expert’s importance, farmer importance and food dealer importance.  The results revealed that the descending order of relative importance of the 12 crop factors are water quality, light intensity, nutrient availability, crop cultivar, substrate media, daylight length, moisture availability, crop spacing, temperature, air freshness, air circulation and relative humidity respectively.  Priority for crop growing factors must be considered while designing and maintaining a protected farm for optimal crop growth and net return

    Challenges for engineering students working with authentic complex problems

    Engineers are important participants in solving societal, environmental and technical problems. However, due to an increasing complexity in relation to these problems new interdisciplinary competences are needed in engineering. Instead of students working with monodisciplinary problems, a situation where students work with authentic complex problems in interdisciplinary teams together with a company may scaffold development of new competences. The question is: What are the challenges for students structuring the work on authentic interdisciplinary problems? This study explores a three-day event where 7 students from Aalborg University (AAU) from four different faculties and one student from University College North Denmark (UCN), (6th-10th semester), worked in two groups at a large Danish company, solving authentic complex problems. The event was structured as a Hackathon where the students for three days worked with problem identification, problem analysis and finalizing with a pitch competition presenting their findings. During the event the students had workshops to support the work and they had the opportunity to use employees from the company as facilitators. It was an extracurricular activity during the summer holiday season. The methodology used for data collection was qualitative both in terms of observations and participants’ reflection reports. The students were observed during the whole event. Findings from this part of a larger study indicated, that students experience inability to transfer and transform project competences from their previous disciplinary experiences to an interdisciplinary setting

    Exploring the practical use of a collaborative robot for academic purposes

    This article presents a set of experiences related to the setup and exploration of potential educational uses of a collaborative robot (cobot). The basic principles that have guided the work carried out have been three. First and foremost, study of all the functionalities offered by the robot and exploration of its potential academic uses both in subjects focused on industrial robotics and in subjects of related disciplines (automation, communications, computer vision). Second, achieve the total integration of the cobot at the laboratory, seeking not only independent uses of it but also seeking for applications (laboratory practices) in which the cobot interacts with some of the other devices already existing at the laboratory (other industrial robots and a flexible manufacturing system). Third, reuse of some available components and minimization of the number and associated cost of required new components. The experiences, carried out following a project-based learning methodology under the framework of bachelor and master subjects and thesis, have focused on the integration of mechanical, electronic and programming aspects in new design solutions (end effector, cooperative workspace, artificial vision system integration) and case studies (advanced task programming, cybersecure communication, remote access). These experiences have consolidated the students' acquisition of skills in the transition to professional life by having the close collaboration of the university faculty with the experts of the robotics company.Postprint (published version
