Multiplexing Could Give Neural Networks a Big Boost

Just as multiplexing can help a single communication channel carry many signals at the same time, a new study reveals that multiplexing can help neural networks scan dozens of streams of data simultaneously, letting them greatly boost the rate at which they analyze information.

How Does a Data Logger Work?

If you are a fan of MadgeTech’s blogs, you probably have seen our previous article “What is a Data Logger & How to Choose the Right One” and perhaps even our educational guide “An Introduction to Data Logging”.  Both pieces of information are useful to help you decide if you need a data logger, what […]

Monitoring Arctic permafrost with satellites, supercomputers and deep learning

Permafrost is important for the planet’s climate, containing large amounts of biomass stored as methane and carbon dioxide, making tundra soil a carbon sink. However, permafrost’s innate characteristics and changing nature are not well understood. Source: What’s New in Measurement and Control?…

Temperature Studies: What is Temperature Validation?

Temperature Studies: What is Temperature Validation?

When it comes to complying with regulatory guidelines and requirements, temperature monitoring tasks can become complex. That’s why it’s important to understand the terminology and differences between temperature qualification, temperature validation, and temperature mapping.

Achievement of 0.005% combined transfer uncertainties in the NIST detector calibration facility

Improvements in a lamp-monochromator-based facility at the National Institute of Standards and Technology (NIST), the Visible near-infrared Spectral Comparator Facility (VisSCF) which is used to calibrate optical detectors for spectral radiant power responsivity from 300 nm to 1100 nm, are described. These changes include extending the VisSCF operational range down to 300 nm from 350 nm, thereby fully covering the ultraviolet-A (UVA) spectral region and partially covering the UVB range. These improvements have lowered the magnitudes of most of the components in the uncertainty budget…

Spectral irradiance scale realization and uncertainty analysis based on a 14 mm diameter WC–C fixed point blackbody from 250 nm to 2500 nm

Spectral irradiance scale in the wavelength range from 250 nm to 2500 nm was realized at National Institute of Metrology on the basis of a large area tungsten carbide–carbon (WC–C) high temperature fixed point blackbody, which is composed of a 14 mm diameter WC–C fixed point cell and a variable temperature blackbody BB3500MP as a furnace. A series of 1000 W FEL tungsten halogen lamps were used as transfer standards. The new spectral irradiance scale was compared with the scale based on a variable-temperature blackbody…

The irony of the magnet system for Kibble balances—a review

The magnet system is an essential component of the Kibble balance, a device that is used to realize the unit of mass. It is the source of the magnetic flux, and its importance is captured in the geometric factor Bl . Ironically, the Bl factor cancels out and does not appear in the final Kibble equation. Nevertheless, care must be taken to design and build the magnet system because the cancellation is perfect only if the Bl is the same in…

Detecting crop nitrogen with hyperspectral sensors on planes

The sensing technique is not only very fast, it also provides much higher spectral and spatial resolution of nitrogen status and photosynthetic capacity than similar studies using satellite imagery. Source: What’s New in Measurement and Control?…
