1. Economically optimal farmer supervision of crop robots

Author:
Elias Maritan; James Lowenberg-DeBoer; Karl Behrendt; Kit Franklin

Smart agricultural technology 2023 v.3 pp. 100110
ISSN:
2772-3755
Subject:
farm management; farmers; humans; models; technology; California
Abstract:
... One of the key issues in regulation of crop robots is the need for human supervision. Economic analysis indicates that autonomous farming potentially reduces agricultural production costs, but such costs may often become higher than conventional when constant on-site human supervision is required by law. However, there are cases where a higher level of crop robot supervision helps maximise profits ...

Subject:
Bayesian theory; data collection; electroencephalography; models; spectral analysis; time series analysis; wind speed; California
Abstract:
... Spectral analysis discovers trends, periodic and other characteristics of a time series by representing these features in the frequency domain. However, when multivariate time series are considered, and the number of components increases, the size of the spectral density matrix grows quadratically, making estimation and inference rather challenging. The proposed novel Bayesian framework considers ...

Abstract:
... Biodiversity plays important roles in nature's contributions to people (i.e., ecosystem services), but the critical details of how biodiversity contributes are challenging to determine. Efforts to identify the components of an ecosystem that provide services have improved our understanding of which species, functional groups, population, or habitats directly provide services. However, species do n ...

However, archaeological and ethnographic evidence suggests that for millennia, co ...
