Remote meetings have become the norm for most students learning synchronously at a distance during the ongoing coronavirus pandemic. This has motivated the use of artificial intelligence in education (AIED) solutions to support the teaching and learning practice in these settings. However, the use of such solutions requires new research particularly with regards to the human factors that ultimately shape the future design and implementations. In this paper, we build on the emerging literature on human-centred AIED and explore students' experiences after interacting with a tool that monitors their collaboration in remote meetings (i.e., using Zoom) during 10 weeks. Using the social translucence framework, we probed into the feedback provided by twenty students regarding the design and implementation requirements of the system after their exposure to the tool in their course. The results revealed valuable insights in terms of visibility (what should be made visible to students via the system), awareness (how can this information increase students' understanding of collaboration performance), and accountability (to what extent students take responsibility of changing their behaviours based on the system's feedback); as well as the ethical and privacy aspects related to the use of collaboration analytics tools in remote meetings. This study provides key suggestions for the future design and implementations of AIED systems for remote meetings in educational settings.

Impending deadlock is difficult to detect on the track of the unified automated material handling systems in 300 mm wafer fabrications, and has been less examined. This paper proposes an impending deadlock detection model using a graphic formulation with new concepts of critical chains and shared nodes. A novel controlling method is presented to ensure critical chains have at least one empty node and sequence the OHTs' entry of the shared nodes. This method is easy to apply and features real-time operation and large-scale systems. The effectiveness and efficiency of the proposed method is confirmed by simulation experiments.
