Experimental Examination of the Heat Transfer in a High Power Eddy Current Brake with a Magneto-isotropic Material Structure

open access: yes, 2022
In this article, the heat transfer of a magnetoisotropic material structure in a water-cooled high-power eddy current brake is investigated. The aim of this work is to evaluate the maximum possible heat density and Nusselt correlation of the given ...

Multiobjective Optimization of Hydrogen‐Assisted Calophyllum inophyllum Biodiesel Operation in a Compression Ignition Engine

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 2897-2929, June 2026.
Tri‐fuel diesel–Calophyllum inophyllum biodiesel–hydrogen operation was tested over 96 points in a diesel engine. Eight performance and emission metrics feed a preference‐agnostic Bootstrapped Empirical Multiobjective Ranking and Selection methodology, revealing load‐blend‐hydrogen windows that increase efficiency, restrain smoke, and expose NOx trade ...

The Dilution Paradox in Extracellular Vesicle Flow Cytometry

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
ABSTRACT Concentrations of extracellular vesicles (EVs) can be measured by flow cytometry, which detects fluorescence and light scattering signals from single particles. To ensure single particle detection, plasma samples are diluted based on their particle concentration, which can differ 100‐fold between samples.

Analytical results for rotating and linear magnetic brakes

open access: yesAdvanced Electromagnetics, 2018
A theory of magnetic damper (eddy-current brake) which can be applied to axial-flux rotating and linear systems moving under the influence of an arbitrary arrangement of magnetic poles is derived from basic electromagnetic principles.

Parametric Study of Eddy Current Brakes for Small-Scale Household Wind Turbine Systems

open access: yesEnergies, 2021
The design and application of eddy current brakes (ECBs) should be simple; further, ECBs should be used semi-permanently. This study aimed to determine major parameters for designing an ECB that can be applied to a small-scale wind turbine generator.

Representing, Re‐presenting, or Producing the Past? Memory Work amongst Museum Employees

open access: yesJournal of Management Studies, Volume 63, Issue 4, Page 1739-1770, June 2026.
Abstract Though it is widely understood that the past can be an important resource for organizations, less is known about the micro‐level skills and choices that help to materialize different representations of the past. We understand these micro‐level skills and choices as a practice: ‘memory work’ – a banner term gathering various activities that ...

Pregnancy shifts endothelial progenitor cell morphology and function: Role of metabolism, pro‐inflammatory cytokines and fetal sex

open access: yesThe Journal of Physiology, Volume 604, Issue 11, Page 4585-4604, 1 June 2026.
Abstract figure legend We recruited non‐pregnant women (NP), women in early pregnancy (EP) and late pregnancy (LP) for isolation of endothelial colony forming cells (ECFCs) via density gradient centrifugation. Plasma supernatant was collected for analysis of markers of glucose and lipid metabolism (fasting glucose, triglycerides, cholesterol, low ...

Eddy Current Brake Design for Operation with Extreme Back-drivable Eddy Current Motor [PDF]

open access: yes, 2010
ME450 Capstone Design and Manufacturing Experience: Winter 2010Traditional electric motors have a tradeoff between high torque and low rotor inertia. The goal of this project is to eliminate using the physics of eddy currents.

Heat generation problem in the eddy current brake: a mini-review

open access: yesCogent Engineering
One of the functions of a brake system is to reduce or maintain the speed of a vehicle. The braking process generally converts kinetic energy into heat.
