Optimizing miniature phase change cells for in-process self-validating thermocouples

J. Pearce¹, D. Tucker¹, P. Williams², P. Cowley², T. Ford²
¹National Physical Laboratory
²CCPI Europe

Thermocouples are widely used in industry for process temperature measurement. Calibration drift is a well-known problem which adversely affects process control, particularly in harsh environments (e.g. high temperature). To overcome this, a mechanism for self-calibration of ... En savoir plus

Bridge Scour Detection of the Feather River Bridge in Yuba City, CA through the use of Finite Element Modeling and Infrasound

A. Jordan [1], D. Whitlow [1], S. McComas [1], M. H. McKenna [1],
[1] U.S. Army Engineer Research and Development Center, Vicksburg, MS, USA

Ongoing studies by the US Army Engineer Research and Development Center (ERDC) are investigating infrasound as a means of persistent monitoring and scour detection at bridges through analysis of the frequency change of the structure caused by altered boundary conditions. Bridges ... En savoir plus

Physics-Based Modeling of Lithium Plating on Graphite Anode of Commercial Lithium-Ion Batteries

Sina Navidi¹, Benjamin Nowacki¹, Aidan Lawlor¹, Jun Xu ², Chao Hu¹
¹School of Mechanical, Aerospace, and Manufacturing Engineering, University of Connecticut, Storrs, CT, USA
²Department of Mechanical Engineering, University of Delaware, Newark, DE, USA

Lithium plating on the graphite anode is a significant factor contributing to the degradation of cell capacity, initiation of internal short circuits, and escalation of thermal runaway in lithium-ion batteries. Non-intrusive detection methods for lithium plating are critical for the safe ... En savoir plus

Electro-Thermal Modeling of a Gated-Graphene Device

A. Paniz¹, A. Moschettini¹, F. Van Veen¹, M. L. Perrin¹
¹EMPA (ETH Zürich), Dübendorf, ZH, Switzerland

The thermoelectric response of a nanoscale device can be characterized by measuring either the open-circuit thermovoltage or the closed-circuit thermocurrent. While theoretically equivalent through the device's conductance, the thermocurrent measurement offers significant practical ... En savoir plus

COMSOL Simulation of Transcutaneous O₂ Transport for Accurate Personalized Respiratory Monitoring

Mohammed Almatrood¹, Bige Unluturk¹
¹Michigan State University, East Lansing, MI, USA

Accurate, real-time measurement of arterial oxygen partial pressure (PaO₂) is essential for managing respiratory diseases and critical care conditions. Traditional arterial blood sampling for PaO₂ is invasive, painful, and provides intermittent snapshots rather than continuous ... En savoir plus

Modeling of a Hybrid-Integrated Moving Magnet Drive for a Quasi-Static 2D-MEMS Vector Scanner

Klemens Birnbaum¹, Martin Blasl², Benjamin Mustin², Thilo Sandner²
¹Institute of Automation, Faculty of Electrical and Computer Engineering, TUD Dresden University of Technology, 01062 Dresden, Germany
²Fraunhofer Institute for Photonic Microsystems, Maria-Reiche-Str. 2, 01109 Dresden, Germany

Quasi-static 2D-MEMS vector scanners are micro-opto-electro-mechanical systems (MOEMS) made of monocrystalline silicon. The primary application for these controllable micromirrors is the high dynamic and precise deflection of laser beams, for example in light detection and ranging ... En savoir plus

Non Destructive Evaluation Division, Metallurgy and Materials Group, Indira Gandhi Centre for Atomic Research, Kalpakkam Tamil Nadu, India

Three-dimensional finite element (FE) modeling of magnetic flux leakage (MFL) technique has been performed using COMSOL 3.4 for prediction of leakage fields from surface and sub-surface defects in a 12 mm thick carbon steel plate. The tangential and normal components of leakage fields ... En savoir plus

Towards Magnetic Induction Tomography of low conductivity: A COMSOL Multiphysics simulation

Julen Eccleston Etxeberria¹, Thomas Smith¹, Alister Davis¹, Christopher Morley¹, Adam Taylor¹, Mark Fromhold¹, Niall Holmes¹
¹University of Nottingham

Background: Magnetic Induction Tomography (MIT) is an electromagnetic imaging technique that maps a material's electrical conductivity by inducing eddy currents via a primary oscillating magnetic field. The resulting secondary magnetic fields from the eddy currents are measured for image ... En savoir plus
