The dramatic increase in man-made radio frequency (RF) fields in the environment during the last few decades has led to public health concerns in many parts of the world. Specifically, questions have been raised on the safety of exposure to RF energy emitted from radar, television and radio communication systems, microwave ovens, video display terminals, and most recently, mobile telephones and base stations, Wi-Fi, LTE, and 5G. Wearable RF gadgets are prevailing. Wireless power transmission is a newer subject, which can involve high intensity exposures. The IEEE EMF database now has more than 6800 original, peer-reviewed papers useful for public health risk assessment of RF exposure. Even there has been 70 years of research, and WHO indicated that scientific knowledge in this area is now more extensive than for most chemicals and current evidence does not confirm the existence of any health consequences from exposure to low level electromagnetic fields, controversy on RF safety continues. Both biological and engineering complexities make the validity of many studies questionable. In this presentation, research, standards, regulation and risk communication concerning RF safety will be addressed.

Issues in Digital Audio That Persist To This Day   With Speakers James J. (JJ) Johnston and Bob Smith   Presented by AES Pacific Northwest Section and IEEE Seattle SPS (SeaSiPS)   There has been a lot of argument, dispute, complaining, and shouting about tracks being too loud or too close to digital maximum. In this talk, we will show: what happens to your signal, its spectrum, and its loudness (remember, loudness is a perceived quantity) how this affects the ability to be transmitted via bit-rate reduction systems how it affects standard "lossless" codecs using graphics and audio clips, what happens to your music when you clip it digitally, cause intersample overs, and/or hypercompress in the name of LOUD how this sort of clipping causes aliasing of other clipping byproducts and how intersample overs make a DAC fall apart in a different way how a pleasant sound can become something else altogether using a variety of statistics on particular clips taken directly from their intended digital delivery streams, exhibiting clipping, what one might call enlightened clipping, level compression, intersample overs, changes in loudness over a track, and how much spectral dynamic range there is in a variety of digital streams that encoding/decoding such streams, especially with lossy codecs can create MORE clipping and MORE intersample overs, forcing both more distortion and higher required data rates for the reduced-rate music. We are not going to talk about artistic judgements that are supposed to be LOUD, but rather about what happens after mastering when a clip has been pushed beyond reason. KEEP IT DOWN A BIT. If you want to clip, do leave some headroom. That way, rather than having a delivered result that depends entirely on the actual DAC the listener is using, you can guarantee your market a consistent experience.

  Utilities need to know the grid topology and loads to perform any meaningful grid optimization task. Rather than passively collecting data from sensors and meters, this talk puts forth an active data acquisition scheme termed grid probing. The idea is to leverage smart inverters to probe an electric grid and record its voltage response at probed buses, with the purpose of grid learning. Grid probing can be performed by commanding inverters to perturb their power injections. Multiple probing actions can be induced within a few tens of seconds. We will explain how probing can be used to infer: a) non-metered loads; and b) feeder topologies. For non-metered loads, we assume the topology to be known and that non-metered loads do not change significantly during probing. By coupling the power flow equations across time, we are able to identify non-metered loads under specific placement conditions, which can be easily checked beforehand. Our analysis and solvers can handle phasor and/or magnitude-only voltage data. We have also designed inverter injections to improve load recovery and ensure safe feeder operation. Grid probing can be also used for recovering grid topologies even without knowing the loads at non-probing buses: Probing all terminal buses on a radial feeder and measuring voltages at all buses, the topology and line impedances can be uniquely recovered. If voltages are recorded only at probing buses, then a reduced grid bearing several similarities to the original grid can be recovered. Speaker(s): Vasesilis, Location: Seattle, Washington
