ATECSolutions What is EMC Testing? EMC testing is the measurement of a device's immunity to RF emissions (EMI), and its RF emission levels. The device must meet IEC, MIL-STD, RTCA/DO-160, or related test standards. Product Category Groups...
a factor 3 regarding SO2 emissions in 2100. SO2 is a good marker of local (or “classical”) industrial pollution, and is a aerosol precursor, or a “climate cooler”. It’s interesting to note that the set of scenarios now used, and that were published in 2000, are...
This study reveals that the regional environmental-based technology (EBT) effect is the key curbing factor for PM2.5emissions, followed by the regional PEI effect. The curbing effect of regional EBT on PM2.5emissions is strong in East China and weak in Northeast China. The environment-oriented ...
First of all, travelling by public transportation is a great idea and effective way to reduce the carbon emission and energy waste. When we go out, we could choose to take an underground or a bus instead of driving a car. Riding a bi...

Q factor (Q) is a measure of the dissipative characteristic of an inductor. High Q inductors have low dissipation and are used to make finely-tuned, narrow-band circuits. Low Q inductors have higher dissipation that results in wideband performance.What is the Self Resonant Frequency of an ...
Learn how to determine the cause of electromagnetic coupling by understanding how it is coupled from source to receiver.
[Every body emits infrared radiation. Blackbodies absorb and emit 100% of the radiation related to their temperature. All other bodies are placed in relation to this when evaluating their radiation emission, called emissivity.
Since the introduction of first emission regulations, emission levels of NOx and PM from diesel engines have been reduced by about 2 orders of magnitude—a factor of 100. It is interesting to look back at the historical emission levels from unregulated engines and engines compliant with the ...
The first version of this post had an error in Figure 1. It has been fixed along with the associated text (7/5/2021). By Andy May The IPCC claims, in their AR5 report, that ECS, the long-term temperature change due to doubling the atmospheric CO2 concent
