Summary: Ultra Wide Band (UWB) is utilized in indoor navigation/localization systems for its reliability, accuracy, and energy efficiency. However, challenges remain in addressing Non Line of Sight (NLoS) links and limited battery life of UWB beacons. To overcome these challenges, a node selection framework called DQLEL is introduced, utilizing Deep Q-Learning to optimize UWB beacon selection based on 2-D Time Difference of Arrival (TDoA). Evaluation shows that DQLEL outperforms other frameworks in link conditions, battery life deviation, location error, and cumulative rewards.

Summary: This paper presents an analysis and optimization of ultra-low-power and ultra-low-voltage CMOS voltage references using four different technologies (180 nm, 90 nm, 65 nm, and 28 nm). The paper also introduces a variability-aware CAD tool for designing these voltage references under the effects of deep-nanometer nodes. Post-layout simulation results show that the CAD tool can design voltage references with excellent Figure-of-Merit (FoM) performance, and the final remarks provide guidance on selecting the best voltage reference topology depending on the CMOS technology.

Summary: High Voltage (HV) overhead power lines are systems that transport large amounts of electrical energy over long distances. Monitoring the state variables of these power lines is crucial for optimizing real-time capability and assessing their health. This paper proposes a Wireless Sensor Network (WSN) with a maximum power point tracker (MPPT) to improve the line's ampacity and maintain operating variables within their rated values. The behavior of the MPPT is analyzed based on electromagnetic field laws and properties of magnetic materials, and validated through experimental tests. A prototype is also created and tested for real operating conditions, including harsh fault conditions.
