Vacuum Tube Plus MOSFET Equals Vacuum Transistor
IEEE Spectrum recently sent out a “Tech Alert” that included an article about vacuum transistors, which combine vacuum tubes and metal oxide semiconductor field-effect transistors (MOSFETs). The article suggests that this technology may wind up replacing traditional silicon transistors.
Converting the High Flux Isotope Reactor to LEU Fuel
Under an initiative by the National Nuclear Security Administration (NNSA), nuclear research reactors currently using highly enriched uranium (HEU) fuel must be converted to low enriched uranium (LEU) fuel with a goal to help prevent the spread of material that can be used to create nuclear weapons. Nuclear engineers at Oak Ridge National Laboratory have turned to multiphysics simulation in order to precisely and accurately explore new designs for the safe conversion of the ORNL High Flux Isotope Reactor.
Automatically Handling Selections in COMSOL Multiphysics®
This is Part 3 of a blog series on how to handle selections and entity numbers when using LiveLink™ for MATLAB® and the COMSOL® Application Programming Interface (API). In this section, I’ll discuss how the internal handling of selections and entity numbers in COMSOL Multiphysics® simulation software is performed and how you can utilize these methods when setting up your own models.
How to Join Solutions in COMSOL Multiphysics
In engineering analysis, the need to compare solutions obtained under different circumstances frequently arises. Some possible scenarios include comparing the effect of different load or parameter configurations, and enveloping results to find the worst or best case at each point of the domain. In each of these and other similar cases, you need access to more than one data set. Here’s how to accomplish such tasks using COMSOL Multiphysics.
FIRST® Robotics at PTC® Live Global 2014
A couple of weeks ago, we exhibited at PTC® Live Global. In addition to manning the exhibition booth and learning about PTC® Creo® Parametric™ 3.0, we were introduced to a fantastic program called FIRST®, which gets kids involved in science and technology.
Getting the Most out of Client-Server Mode
When using COMSOL Multiphysics on a Floating Network License, it is possible to use the Client-Server mode of operation to access remote computing resources for solving large models, while still using the graphics card on a local machine to display graphics. This can have some significant advantages, so let’s look at Client-Server mode in more detail.
Studying Sonar Systems on a Component Level
Sound Navigation and Ranging (SoNaR, more commonly written in all lowercase as “sonar”) technology can be used for investigating and communicating underwater. To improve the sonar system, you need to optimize the design at a component level. A major component of sonar is the electro-acoustic transducer.
Seas of Change for Wind Turbines
Wind turbine noise is a (hotly disputed) topic that we’ve mentioned on the blog before. While research into noise production by wind farms is still being debated among researchers, one way we’ve found to overcome these noisy turbine troubles is to place turbines offshore where they can’t be heard and, conveniently, high winds with more regularity make energy production more effective. However, a question that comes to mind is: What impact do offshore wind farms have on marine life?
