Universities provide subsidies to students with economic hardship every year. However, the traditional method cannot accurately find those who really need help. Recently, students often use e-cards to consume in campus, and the consumption data from e-cards reflect the students' behaviours. In this paper, a data-driven method which combines statistical methods with machine learning classification algorithms (SM2L) is proposed to identify students with economic hardship by using consumption data. First, SM2L extracts seven features about meals and bath and excludes some abnormal consumption individuals according to consumption time and amount. Second, three classification algorithms are used to classify students and get different numbers of students with economic hardship by adjusting the parameters. Third, output the intersection of the result from phase 2 and the students who consume more in school. Experiments show that SM2L can accurately identify students with economic hardship.

This paper derives the throughput of wireless communications using reconfigurable intelligent surfaces (RIS) when the source harvests power from wind, radio frequency (RF) signals and the sun. The harvested power from wind is proportional to the power of three of wind speed and depends also on rotor radius r and air density. The harvested power from RF signals is proportional to the squared absolute value of channel coefficient. The harvested power from the sun uses a photo voltaic (PV) system and is proportional to radiation intensity. The radiation intensity is Gaussian and takes into account weather effects such as cloud occlusion. We show that hybrid energy harvesting using both the wind, RF signal, and solar energy offers the largest throughput.

Wireless body area network (WBAN) is becoming increasingly popular among researchers and patients due to its real-time healthcare services. Mobile-edge computing (MEC) can play a major role to satisfy the latency requirements of WBAN's healthcare applications. The development of a suitable computation offloading and energy savings scheme is critical for MEC-enabled WBANs due to different priorities of WBAN tasks, QoS, resource availability, and contention delay. To improve the end-to-end latency, this paper proposes a fast data transfer, emergency timeslot, processing node allocation, and energy-saving-based task execution strategy (FETES) considering WBAN user's task priority, multiple tasks, resources, availability, different delays, network connectivity, and processing devices for computation offloading. The FETES scheme supports energy-saving for sensors, hubs, and network access devices. To evaluate the delay, throughput, and energy dissipation performance of the proposed FETES scheme, a comprehensive analytical model is presented. The evaluation results show the efficacy of the proposed FETES scheme.
