Precision yield estimation and mapping in manual strawberry harvesting with instrumented picking carts and a robust data processing pipeline
Uddhav Bhattarai, Rajkishan Arikapudi, Chen Peng +3
High-resolution yield maps for manually harvested crops are impractical to generate on commercial scales because yield monitors are available only for mechanical harvesters. Howeve…
Data-Driven Worker Activity Recognition and Efficiency Estimation in Manual Fruit Harvesting
Uddhav Bhattarai, Rajkishan Arikapudi, Steven A. Fennimore +2
Manual fruit harvesting is common in agriculture, but the amount of time pickers spend on non-productive activities can make it very inefficient. Accurately identifying picking vs.…
Self-supervised Learning for Panoptic Segmentation of Multiple Fruit Flower Species
Abubakar Siddique, Amy Tabb, Henry Medeiros
Convolutional neural networks trained using manually generated labels are commonly used for semantic or instance segmentation. In precision agriculture, automated flower detection…
Comparison of downscaling techniques for high resolution soil moisture mapping
Sabah Sabaghy, Jeffrey Walker, Luigi Renzullo +19
Soil moisture impacts exchanges of water, energy and carbon fluxes between the land surface and the atmosphere. Passive microwave remote sensing at L-band can capture spatial and t…
A framework to evaluate whether to pool or separate behaviors in a multilayer network
Annemarie van der Marel, Sanjay Prasher, Chelsea Carminito +4
A multilayer network approach combines different network layers, which are connected by interlayer edges, to create a single mathematical object. These networks can contain a varie…
Comments on "An evaluation of hurricane superintensity in axisymmetric numerical models" by Raphaël Rousseau-Rizzi and Kerry Emanuel
Anastassia M. Makarieva, Andrei V. Nefiodov, Douglas Sheil +4
In a recent paper Rousseau-Rizzi and Emanuel (2019) presented a derivation of an upper limit on maximum hurricane velocity at the surface. This derivation was based on a considerat…
How to model honeybee population dynamics: stage structure and seasonality
Jun Chen, Komi Messan, Marisabel Rodriguez Messan +3
Western honeybees (Apis Mellifera) serve extremely important roles in our ecosystem and economics as they are responsible for pollinating $ 215 billion dollars annually over the wo…
Population dynamics of Varroa mite and honeybee: Effects of parasitism with age structure and seasonality
Komi Messan, Marisabel Rodriguez Messan, Jun Chen +2
Honeybees play an important role in the production of many agricultural crops and in sustaining plant diversity in undisturbed ecosystems. The rapid decline of honeybee populations…
Peanut Maturity Classification using Hyperspectral Imagery
Sheng Zou, Yu-Chien Tseng, Alina Zare +3
Seed maturity in peanut (Arachis hypogaea L.) determines economic return to a producer because of its impact on seed weight (yield), and critically influences seed vigor and other…
The Use of Agricultural Robots in Orchard Management
Qin Zhang, Manoj Karkee, Amy Tabb
Book chapter that summarizes recent research on agricultural robotics in orchard management, including Robotic pruning, Robotic thinning, Robotic spraying, Robotic harvesting, Robo…
Solving the Robot-World Hand-Eye(s) Calibration Problem with Iterative Methods
Amy Tabb, Khalil M. Ahmad Yousef
Robot-world, hand-eye calibration is the problem of determining the transformation between the robot end-effector and a camera, as well as the transformation between the robot base…
Multispecies fruit flower detection using a refined semantic segmentation network
Philipe A. Dias, Amy Tabb, Henry Medeiros
In fruit production, critical crop management decisions are guided by bloom intensity, i.e., the number of flowers present in an orchard. Despite its importance, bloom intensity is…
Apple Flower Detection using Deep Convolutional Networks
Philipe A. Dias, Amy Tabb, Henry Medeiros
To optimize fruit production, a portion of the flowers and fruitlets of apple trees must be removed early in the growing season. The proportion to be removed is determined by the b…
Automatic segmentation of trees in dynamic outdoor environments
Amy Tabb, Henry Medeiros
Segmentation in dynamic outdoor environments can be difficult when the illumination levels and other aspects of the scene cannot be controlled. Specifically in orchard and vineyard…
Two-strain competition in quasi-neutral stochastic disease dynamics
Oleg Kogan, Michael Khasin, Baruch Meerson +2
We develop a new perturbation method for studying quasi-neutral competition in a broad class of stochastic competition models, and apply it to the analysis of fixation of competing…
Worldwide Patterns of Ancestry, Divergence, and Admixture in Domesticated Cattle
Jared E. Decker, Stephanie D. McKay, Megan M. Rolf +17
The domestication and development of cattle has considerably impacted human societies, but the histories of cattle breeds have been poorly understood especially for African, Asian,…
The genomic impacts of drift and selection for hybrid performance in maize
Justin P. Gerke, Jode W. Edwards, Katherine E. Guill +2
Modern maize breeding relies upon selection in inbreeding populations to improve the performance of cross-population hybrids. The United States Department of Agriculture - Agricult…
Adjusting for Misclassification: A Three-Phase Sampling Approach
Hailin Sang, Kenneth K. Lopiano, Denise A. Abreu +3
The United States Department of Agriculture's National Agricultural Statistics Service (NASS) conducts the June Agricultural Survey (JAS) annually. Substantial misclassification oc…
The rise and fall of the Phytophthora infestans lineage that triggered the Irish potato famine
Kentaro Yoshida, Verena J. Schuenemann, Liliana M. Cano +10
Phytophthora infestans, the cause of potato late blight, is infamous for having triggered the Irish Great Famine in the 1840s. Until the late 1970s, P. infestans diversity outside…
Epidemic fronts in complex networks with metapopulation structure
Jason Hindes, Sarabjeet Singh, Christopher R. Myers +1
Infection dynamics have been studied extensively on complex networks, yielding insight into the effects of heterogeneity in contact patterns on disease spread. Somewhat separately,…
The Genomic Signature of Crop-Wild Introgression in Maize
Matthew B. Hufford, Pesach Lubinksy, Tanja Pyhäjärvi +3
The evolutionary significance of hybridization and subsequent introgression has long been appreciated, but evaluation of the genome-wide effects of these phenomena has only recentl…
