New sensing method: Japanese scientists demonstrated a fiber-optic strain sensor that reads interference patterns in the electrical spectrum instead of using optical analyzers. Why it matters: The ...

An interlaboratory comparison across nine metrology institutes found generally good agreement in solar cell calibration under ...

Decoupling ultrasonic flowmeter calibration from spool fabrication can recover weeks — often significantly more — from ...

👉 Learn how to solve for an unknown variable using parallel lines and a transversal theorems. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Traditional DP flow measurement is focused on volume, not mass. Historical equation development was complicated and iterative. Rather than correcting deviations from theory, the Energy Correlation ...

In the past two decades, impact evaluation has become an unavoidable topic in the social sector. Yet beyond the discourse on how to measure social impact lies a structural problem: We are not ...

Telomeres are nucleoprotein complexes at chromosome ends, composed of tandemly repeated specific DNA sequences along with associated proteins. In somatic cells, telomeres progressively shorten with ...

Abstract: Defects are inevitable on fabric surfaces during the weaving process, and their size is the primary criterion for fabric quality rating. Existing methods primarily rely on computer vision ...

Parking is not always an easy task. Sometimes spots are too tight, too small or positioned strangely — not to mention the potential obstacles hindering your perfect parking, like other vehicles, trees ...

Have you ever wondered how a robot navigates a cluttered room or how a drone maintains its altitude with pinpoint accuracy? The secret lies in the tools used to measure distance, an often-overlooked ...

A new method for quantifying grandeur is reshuffling the pecking order of the planet’s most impressive peaks. Turns out Everest has steep competition. Mount Everest, left, tops out at 29,032 feet ...
