An Analytical Thermal Model for Coaxial Magnetic Gears Considering Eddy Current Losses

Modelling
This work presents an analytical 2D model for estimating eddy current losses in the permanent magnets (PMs) of a coaxial magnetic gear (CMG), with a focus on loss minimization through magnet segmentation.

Deep Learning Approaches for Classifying Crack States With Overload and Predicting Fatigue Parameters in a Titanium Alloy

Advanced Intelligent Systems, EarlyView.
This study proposes a deep learning approach to evaluate the fatigue crack behavior in metals under overload conditions. Using digital image correlation to capture the strain near crack tips, convolutional neural networks classify crack states as normal, overload, or recovery, and accurately predict fatigue parameters.

Intelligent Operator‐Independent Flexibility in Robotic Non‐Destructive Evaluation

Advanced Intelligent Systems, EarlyView.
Non‐destructive evaluation of high‐value components remains a manufacturing bottleneck due to rigid robotic calibration and fixturing. This study presents a flexible, adaptable system integrating 3D vision and force‐position control with a collaborative KUKA LBR robot. The geometry‐agnostic system enables pose‐independent ultrasonic inspection, detects

A high‐fat diet with vitamin D and propylthiouracil produces a pro‐atherogenic phenotype in rats

Animal Models and Experimental Medicine, EarlyView.
Male Sprague–Dawley rats received a cholesterol‐rich high‐fat diet supplemented with vitamin D and propylthiouracil for 11 weeks. The model induced dyslipidemia (increased total cholesterol/low‐density lipoprotein, decreased triglycerides), inflammation (increased interleukin‐6 and serum amyloid A), hypercalcemia, and reduced circulating endothelial ...

Energy Loss of Magnetic Coupling for Pump

Energies
To investigate the energy loss characteristics of magnetic pumps, an experimental setup for magnetic transmission in pumps was constructed. Through experiments, the impact of various factors on the eddy current loss of the magnetic coupling was examined,

Individualized Atrophy‐Based Prediction of Dementia Progression in Familial Frontotemporal Lobar Degeneration With Bayesian Linear Mixed‐Effects Modeling

Annals of Neurology, EarlyView.
Objective Age of symptom onset is highly variable in familial frontotemporal lobar degeneration (f‐FTLD). Accurate prediction of onset would inform clinical management and trial enrollment. Prior studies indicate that individualized maps of brain atrophy can predict conversion to dementia in f‐FTLD.

Temporal Modeling of Amyloid and Tau Trajectories in Alzheimer's Disease Using PET and Plasma Biomarkers

Annals of Neurology, EarlyView.
Objective This study aimed to compare positron emission tomography (PET) and plasma‐based temporal modeling of amyloid and tau biomarkers in Alzheimer's disease. Methods Longitudinal amyloid PET (n = 1,097, mean age ± SD = 72.5 ± 7.38 year, 51.4% male), 18F‐flortaucipir tau‐PET (n = 230, 74.3 ± 7.18 year, 52.2% female), and Fujirebio Lumipulse plasma p‐

Eddy current losses in transformer windings

, 2020
Målet med denne masteroppgaven er å undersøke en semi-analytisk tapberegningsmetode, spesielt når man tar hensyn til virvelstrømstap i transformatorviklinger. Dette gjøres gjennom sammenligninger mellom simulerte og målte resultater, og gjennom sammenligninger av målte og nominell data fra produsenten.
