Investigating the spatiotemporal characteristics of motion fields using three‐dimensional radar echoes to construct an ensemble nowcasting system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The process of developing and validating the ensemble nowcasting system in this study. Abstract In this study, a spatial and temporal analysis of three‐dimensional motion fields was conducted to formulate an ensemble nowcasting scheme. These motion fields were derived from radar data covering the entire volume and were analyzed across space and time ...

Lumped and distributed‐parameter pipe model framework for thermal transients: State‐space and transfer function theory and application to multi‐energy systems

IET Renewable Power Generation, Volume 17, Issue 1, Page 199-215, 6 January 2023., 2023
Abstract The accurate prediction and simulation of thermal transients in district heating networks is essential for the meaningful analysis of combined heat and power systems. For this purpose, the focus of this paper lies on the development of a consistent and comprehensive modelling framework that links diverse pipe model categories to specific ...

High‐Throughput Robotic Phenotyping for Quantifying Tomato Disease Severity Enabled by Synthetic Data and Domain‐Adaptive Semantic Segmentation

Journal of Field Robotics, EarlyView.
ABSTRACT Plant diseases cause an annual global crop loss of 20%–40%, leading to estimated economic losses of 30–50 billion dollars. Tomatoes are susceptible to more than 200 diseases. Breeding disease‐resistant cultivars is more cost‐effective and environmentally sustainable than the frequent use of pesticides.

Remote sensing image semantic segmentation network based on ENet

The Journal of Engineering, Volume 2022, Issue 12, Page 1219-1227, December 2022., 2022
Abstract The current image semantic segmentation methods cannot meet the requirements of high precision and high speed for remote sensing image analysis. The ENet network model builds a semantic segmentation network, which has the characteristics of few network parameters and fast operation speed.

A Unified Topological Representation for Robotic Fleets in Agricultural Applications

Journal of Field Robotics, EarlyView.
ABSTRACT Agricultural robots offer a viable solution to the critical challenges of productivity and sustainability of modern agriculture. The widespread deployment of agricultural robotic fleets, however, is still hindered by the overall system's complexity, requiring the integration of several nontrivial components for the operation of each robot but ...

Comparison of wind speed forecasting models for power reserve scheduling in the congested transmission network

The Journal of Engineering, Volume 2022, Issue 12, Page 1228-1238, December 2022., 2022
Abstract Due to its stochastic nature, wind energy imposes unprecedented challenges on the power grid, and a properly scheduled reserve is essential to accommodate wind power's intermittency and volatility. Many power reserve scheduling studies have considered the uncertainties of the renewable energy integration but few address how different wind ...

A Smart Camera With Integrated Deep Learning Processing for Disease Detection in Open Field Crops of Grape, Apple, and Carrot

Journal of Field Robotics, EarlyView.
ABSTRACT Downy mildew (Plasmopara), apple scab (Venturia inaequalis), and Alternaria leaf blight are endemic diseases that affect crops worldwide. The diseases can cause severe losses in grapes, apples and carrots when not detected and treated in an early stage.

Updates in SASfit for fitting analytical expressions and numerical models to small‐angle scattering patterns

Journal of Applied Crystallography, Volume 55, Issue 6, Page 1677-1688, December 2022., 2022
Recent enhancements and additions to the SASfit program are discussed, including anisotropic scattering models, flexible distributions, regularization techniques such as the expectation‐maximization method, and new structure factors, especially for ordered nano‐ and meso‐scaled material.

ROV Teleoperation in the Presence of Cross‐Currents Using Soft Haptics

Journal of Field Robotics, EarlyView.
ABSTRACT The remote operation of underwater vehicles at depth is complicated by the presence of invisible and unpredictable environmental disturbances such as cross‐currents. Communicating the presence of these disturbances to an operator on the surface is made more difficult by the nature of the disturbances and the lack of visible features to ...

Blood diamonds? Responses of open‐source software developers to the Facebook–Cambridge Analytica scandal

Strategic Management Journal, EarlyView.
Abstract Research Summary Corporate scandals often create moral struggles for ecosystem stakeholders who collaborate with scandal‐tainted firms on mutually beneficial projects. We examine how these stakeholders navigate their relationships with such firms.
