A new approach for the robotic exploration of Mars is detailed in this paper: the use of small, ultralightweight, autonomous rotary-wing aerial platforms. Missions based on robotic rotorcraft could make excellent candidates for NASA Mars Scout program. The paper details the work to date and future planning required for the development of such ‘Mars rotorcraft.’

Soil moisture sensors (SMSs) are a useful tool that aid in data-driven water management decisions. However, default factory calibrations can be inaccurate and soil-specific often required to obtain higher accuracy the determination of soil storage plant available water. In this study, we conducted lab calibration for Field Scout TDR 300, which is popular SMS used turfgrass industry. Five soils ...

Numerous particle swarm optimization (PSO) algorithms have been developed for solving numerical problems in recent years. However, most of existing PSO only one search phase. There is no strengthened phase the well-performed particles, and also re-initialization exhausted particles. These issues may still restrict performance complex problems. In this paper, inspired by bee-foraging mechanism a...

Phytotoxicity of aluminum is characterized by a rapid inhibition of root elongation at micromolar concentrations, however, the mechanisms primarily responsible for this response are not well understood. We investigated the effect of Al on the viscosity and elasticity parameters of root cell wall by a creep-extension analysis in two cultivars of wheat (Triticum aestivum L.) differing in Al resis...
