A Sprayer Movement Model for Treating Reeds in Rice Irrigation System
Introduction. Rice grawing is an important branch of crop sector in Kuban, which produces about 80% of Russian rice. One of the significant factors reducing the yield of this crop is the presence of high-stemmed weeds growing in the canals and on the ...

Necessity for quantum coherence of nondegeneracy in energy flow [PDF]
In this work, we show that the quantum coherence among non-degenerate energy subspaces (CANES) is essential for the energy flow in any quantum system. CANES satisfies almost all of the requirements as a coherence measure, except that the coherence within degenerate subspaces is explicitly eliminated.We show that the energy of a system becomes frozen if

"I am the follower, also the boss": Exploring Different Levels of Autonomy and Machine Forms of Guiding Robots for the Visually Impaired [PDF]
Guiding robots, in the form of canes or cars, have recently been explored to assist blind and low vision (BLV) people. Such robots can provide full or partial autonomy when guiding. However, the pros and cons of different forms and autonomy for guiding robots remain unknown. We sought to fill this gap.

Wearable Gait Measurement System with an Instrumented Cane for Exoskeleton Control
In this research we introduce a wearable sensory system for motion intention estimation and control of exoskeleton robot. The system comprises wearable inertial motion sensors and shoe-embedded force sensors. The system utilizes an instrumented cane as a
