Hydrogeologic characterization of a glacial aquifer contaminated by crude oil near Bemidji, Minnesota [PDF]
, 1992 This study investigates the hydrogeology of a glacial sand and gravel aquifer contaminated by crude oil near Bemidji, Minnesota. The goal of this study is to obtain an understanding of the effect of local flow phenomena, glacial stratigraphy, and ...

Coverage Performance of UAV-powered Sensors for Energy-neutral Networks with Recharging Stations [PDF]
arXiv, 2023 The projected number of Internet of Things (IoT) sensors makes battery maintenance a challenging task. Although battery-less IoT is technologically viable, the sensors should be somehow energized, either locally or remotely. Unmanned aerial vehicles (UAVs) can respond to this quest via wireless power transfer (WPT).

A Saint-Venant shallow water model for overland flows with precipitation and recharge [PDF]
Mathematical and Computational Applications (2021) (published
online 29 Dec 2020), 2017 We propose a one-dimensional Saint-Venant (open channel) model overland flows including a water input--output source term modelling recharge via rainfall and infiltration (or exfiltration). We derive the model via asymptotic reduction from the two-dimensional Navier--Stokes equations under the shallow water assumption, with boundary conditions ...

An Enhanced RRT based Algorithm for Dynamic Path Planning and Energy Management of a Mobile Robot [PDF]
arXiv, 2023 Mobile robots often have limited battery life and need to recharge periodically. This paper presents an RRT- based path-planning algorithm that addresses battery power management. A path is generated continuously from the robot's current position to its recharging station. The robot decides if a recharge is needed based on the energy required to travel

Hydrology and Earth System Sciences, 2023 . Understanding groundwater recharge processes is important for sustainable water resource management. Experimental approaches to study recharge in karst areas often focus on analysing the aquifer response using a disintegration of its outlet signals ...
