With liquids density is affected very little by changes in pressure until the pressure is reduced sufficiently for bubbles of vapour to form (which has a much lower density than liquids). The density of gases varies greatly with pressure, in regions where gases behave in a near ideal fashion, the density is approximately proportional to [...]

Attenuation is the process of diluting the starting ingredient to the point that it is nothing but water. Potency is how diluted it is. X means diluted to one tenth strength 10X means diluted to one tenth strength TEN TIMES, or 1 part ingredient, ten billion parts water. C means diluted to one one hundredth [...]

I cannot find much information on this. Any help/links to detailed information would be appreciated. In medical sonography, artifacts can be classified into three categories: 1: Those related to instrument problems, e.g. signals and patterns you might see on a screen that are caused when the instruments are not working properly, or perhaps nearby equipment [...]

I just installed iOS 4 on an iPhone 3GS – and it has the SAME EXACT ISSUE as the iPhone 4. But the iPhone 3GS does not have an external antenna but yet suffers when held the same way as an iPhone 4! This NEVER happened when iOS 3.1.3 was installed. This has to be [...]

Line of sight, atmospheric conditions are the main factors.

Passive probes are the standard probe provided with most oscilloscopes. Typical passive probes provide a 10:1 attenuation and feature a high input resistance of 10 M?. This high input resistance means that passive probes are the ideal tool for low frequency signals since circuit loading at these frequencies is minimized. Passive probes are designed to [...]

I’m not certain if company’s mean 20 log(ratio) or log(ratio). If the first surely the insertion loss is very high, much higher than i’d expect? I have very limited experience of RF/UHF splitters but in general, insertion loss specifies the ratio between how much power is delivered into the device/system and how much is delivered [...]

Clip 3 of 3. Dr. Yousef Bozorgnia of PEER discusses the development of the NGA relationships and future studies being funded by the California Earthquake Authority (CEA) at EQECAT’s 2010 Conference in San Francisco, CA.
