The emerging edge-hub-cloud paradigm has enabled the development of innovative latency-critical cyber-physical applications in the edge-cloud continuum. However, this paradigm poses multiple challenges due to the heterogeneity of the devices at the edge of the network, their limited computational, communication, and energy capacities, as well as their different sensing and actuating capabilities. To address these issues, we propose an optimal scheduling approach to minimize the overall latency of a workflow application in an edge-hub-cloud cyber-physical system. We consider multiple edge devices cooperating with a hub device and a cloud server. All devices feature heterogeneous multicore processors and various sensing, actuating, or other specialized capabilities. We present a comprehensive formulation based on continuous-time mixed integer linear programming, encapsulating multiple constraints often overlooked by existing approaches. We conduct a comparative experimental evaluation between our method and a well-established and effective scheduling heuristic, which we enhanced to consider the constraints of the specific problem. The results reveal that our technique outperforms the heuristic, achieving an average latency improvement of 13.54% in a relevant real-world use case, under varied system configurations. In addition, the results demonstrate the scalability of our method under synthetic workflows of varying sizes, attaining a 33.03% average latency decrease compared to the heuristic.

In the status quo, traffic control systems operate on predetermined patterns and instructions devised from past data. While this method functions effectively for traffic under normal conditions, it becomes heavily congested and inefficient during instances of high traffic, which leads to a multitude of temporal, economic, health, and environmental harms. However, by combining traditional traffic controllers with modern technologies such as Internet of Things devices and computer vision, these issues can be effectively addressed. This research presents a novel, affordable Artificial Intelligence of Things traffic control system that enables accurate real-time vehicle detection and signal control. This work is split into two sections: (1) an AIoT physical system that can scan traffic conditions in real-time and (2) a realistic traffic simulator with a custom optimization algorithm. Combined, this research provides up to 35% greater throughput, 50% reduced waiting time, and 50% reduction in greenhouse gas emission reductions in comparison to non-optimized algorithms used in the status quo. The implementation of this work leads to various temporal, economic, environmental, and health benefits;in addition to providing comparable emission reduction as the complete replacement of all internal combustion engine vehicles with battery electric vehicles, while significantly reducing vehicle travel time, systems installation time, and cost.

Contextualization in education connects learning material to students' experiences and background knowledge to make it relevant and meaningful. It involves placing content in a real-world context to show students the practical applications and relevance of the concepts they are learning. Contextualizing is an important pedagogical strategy. In order to support teachers in this effort, it is necessary to understand what contexts to provide for teachers to make relevant instruction in certain situations. In this paper, we aim to explore: In what context do teachers need students' everyday life experiences to make the class more relevant to students? We conducted focus groups with teachers who shared their contextualizing experiences. The context for contextualizing refers to the information used to characterize the situation in the classroom and the experiences of the students. The results of this research include the three categories of context information, time, activity, and location, that are relevant to the lesson and the students' prior experiences related to these factors. Design implications are discussed in this paper to illustrate how adaptive teacher support systems can provide relevant and meaningful information to the teachers by considering context information and students' prior experiences.
