TL;DR: By adopting Self-Determination Theory as a theoretical framework to model these student needs, this work aims to investigate the impact of FCM-enhanced blended learning environments not only on students' cognitive learning outcomes, but more importantly on their internal dispositions and needs for competence, autonomy and relatedness.

TL;DR: In this paper, the authors investigated the magnitude of the solidification induced residual strains in FDM fabricated parts using different processing parameters, such as layer thickness and deposition orientation, and recorded the developed residual strains at the end of the fabrication process using an optical sensor with a short fiber Bragg grating (FBG) embedded at the midplane of FDM built specimens.

TL;DR: The proposed protocol aims at minimizing the overall network overhead and energy expenditure associated with the multihop data retrieval process while also ensuring balanced energy consumption among SNs and prolonged network lifetime.
Abstract: A large class of Wireless Sensor Networks (WSN) applications involve a set of isolated urban areas (e.g., urban parks or building blocks) covered by sensor nodes (SNs) monitoring environmental parameters. Mobile sinks (MSs) mounted upon urban vehicles with fixed trajectories (e.g., buses) provide the ideal infrastructure to effectively retrieve sensory data from such isolated WSN fields. Existing approaches involve either single-hop transfer of data from SNs that lie within the MS's range or heavy involvement of network periphery nodes in data retrieval, processing, buffering, and delivering tasks. These nodes run the risk of rapid energy exhaustion resulting in loss of network connectivity and decreased network lifetime. Our proposed protocol aims at minimizing the overall network overhead and energy expenditure associated with the multihop data retrieval process while also ensuring balanced energy consumption among SNs and prolonged network lifetime. This is achieved through building cluster structures consisted of member nodes that route their measured data to their assigned cluster head (CH). CHs perform data filtering upon raw data exploiting potential spatial-temporal data redundancy and forward the filtered information to appropriate end nodes with sufficient residual energy, located in proximity to the MS's trajectory. Simulation results confirm the effectiveness of our approach against as well as its performance gain over alternative methods.
