Predicting How Long Coffee Stays Warm in a Vacuum Flask
Do you use a vacuum flask to keep your coffee or tea warm? Try simulating the natural convection cooling in one of these containers to see exactly how long your beverage will stay warm.
Analyzing Time-Domain Reflectometry for 2 Electrical Designs
Here are 2 examples of analyzing the signal integrity and time domain reflectometry in electrical devices: a high-speed interconnect and a set of parallel microstrip lines.
Simulating Extraordinary Optical Transmission at Terahertz Frequencies
One potential approach to improving medical imaging, quality assurance, and other terahertz applications is extraordinary optical transmission, a process that can be studied with RF simulation.
Multiparameter Optimization with a Least-Squares Objective
Learn how to estimate parameters using multiparameter optimization, which will automatically adjust your model based on an underlying data file of experimental parameters.
Designing an Ultrasensitive Imaging System Based on Mantis Shrimp
Mantis shrimp have one of the most advanced visual systems. Researchers used these organisms as inspiration for a medical imaging method that could help improve cancer detection.
When Stars Align (and Collide): A Historic Gravitational Wave Discovery
Imagine going from only reading textbooks with no pictures to seeing a 3D movie. Thanks to a 2017 discovery, astrophysicists experienced a comparable improvement in how they see the universe.
What Is the Physics Behind a Counterweight Trebuchet?
A counterweight trebuchet, a siege weapon commonly seen in movies set in the Middle Ages and fantasy worlds, also happen to be an interesting multibody dynamics problem.
Modeling Surface Reactions in Porous Media and Reactive Pellet Beds
