Monitoring Source Areas of Post‐Fire Geomorphic Processes Using an In Situ Multi‐Sensor System

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Geomorphic processes that occur after wildfires in mountainous areas require a deep understanding due to complex interactions of fire effects with the landscape surface. In situ monitoring systems can support this task, even if some limitations that affect traditional sensors can hamper their action. The current work presents an advanced multi‐

A Drone‐Borne GPR System for Lake and River Ice Thickness Monitoring

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Monitoring ice on water is critical to study global and regional environmental change. However, accurate ice thickness mapping over a water body like a lake is still challenging. In this study, we first develop a drone‐borne ground penetrating radar (GPR) system for ice thickness monitoring.

Determining the Direction of Radio Wave Reception for Maximum Radiation Using Genetic Algorithm and RF to DC Conversion Efficiency Analysis

Engineering Reports, Volume 7, Issue 9, September 2025.
In this study, a new plan for routing radio transmitters is presented using an algorithm compatible with RFEH. The proposed algorithm is based on the genetic algorithm (GA), and in an innovation, using the HPBW in the GA creates a population for initial sampling dependent on the receiver antenna.
