Global Alfven Eigenmodes in the H-1 heliac [PDF]

, 2017
Recent upgrades in H-1 power supplies have enabled the operation of the H-1 experiment at higher heating powers than previously attainable. A heating power scan in mixed hydrogen/helium plasmas reveals a change in mode activity with increasing heating ...

Predicting Mechanical Properties of FDM‐Produced Parts Using Machine Learning Approaches

Journal of Applied Polymer Science, Volume 142, Issue 20, May 20, 2025.
ABSTRACT Additive manufacturing (AM), especially fused deposition modeling (FDM), has been widely used in industrial production processes in recent years. The mechanical properties of parts produced by FDM can be predicted through the correct selection of printing parameters.

Development of high-performance long-pulse discharge in KSTAR

Nuclear Fusion, 2023
High-performance long-pulse plasma operation is essential for producing economically viable fusion energy in tokamak devices. To achieve such discharges in KSTAR, firstly, the rapid increase in the temperature of plasma-facing components was mitigated ...

Wall conditioning and ELM mitigation with boron nitride powder injection in KSTAR

Nuclear Materials and Energy, 2021
Results from KSTAR powder injection experiments, in which tens of milligrams of boron nitride (BN) were dropped into low-power H-mode plasmas, show an improvement in wall conditions in subsequent discharges and, in some cases, a reduction or elimination ...

Application of an Electronic Nose as a New Technology for Rapid Detection of Adulteration in Honey

Applied Sciences, 2023
This work demonstrates the application of an electronic nose (e-nose) for discrimination between authentic and adulterated honey. The developed e-nose is based on electrodes covered with ionogel (ionic liquid + gelatin + Fe3O4 nanoparticle) films ...

Yield prediction models for some wheat varieties with satellite‐based drought indices and machine learning algorithms

Irrigation and Drainage, Volume 74, Issue 1, Page 237-250, February 2025.
Abstract In recent years, frequent drought events in Konya, one of Türkiye's most important cereal production centres, have led to increased pressure on water and soil resources, resulting in yield losses, particularly in wheat production. Alternative yield prediction models, especially those that play a crucial role in agricultural import–export ...
