Pathologic Blood Samples Tolerate Exposure to Vibration and High Turbulence in Simulated Drone Flights, but Plasma Samples Should be Centrifuged after Flight
(2021-01-30)Objective. Most of the previous studies of drone transport of blood samples examined normal blood samples transported under tranquil air conditions. We studied the effects of 1- and 2-hour drone flights using random vibration ... -
Path Planning for UGVs Based on Traversability Hybrid A*
(2021-02-01)In this letter, a new method of path planning for unmanned ground vehicles (UGVs) on terrain is developed. For UGVs moving on terrain, path traversability and collision avoidance are important factors. If traversability ... -
Changes in inoperability for interdependent industry sectors in Norway from 2012 to 2017
(2021-03)The purpose of this work has been to investigate changes in interdependencies between Norway's mainland industry sectors and how it might affect national security. To this end, the interdependencies were analysed by using ... -
Holmium-doped fiber amplifier for pumping a ZnGeP2optical parametric oscillator
