However, using the same set of features for multiple activities can be suboptimal per activity and not take into account the diversity of kinematic movements that could be captured by diverse features.
DOPPLER RADAR ATLANTA PLUS
A common approach in activity classification attempts to find the algorithm (features plus classifier) that can deal with multiple activities analysed in one study such as walking, sitting, drinking and crawling.
Radar-based classification of human activities and gait have attracted significant attention with a large number of approaches proposed in terms of features and classification algorithms. It was demonstrated that the value of the fundamental cadence frequency increases with increasing dynamic movement of people and simultaneously the possibility of its extraction is proportional to the degree of synchronization movements of persons in the group. While the central Doppler frequency can be determined using the autocor-relation and the spectrogram, the extraction of the funda-mental cadence frequency using the autocorrelation is unreliable when the target is in the clutter presence. It was demonstrated that the human motion signature extrac-tion is better using spectrogram analysis. The motion of arms and legs induces modulation on the returned radar signal and generates sidebands around the central Dop-pler frequency, referred to as micro-Doppler signatures. The main contribution comes from the torso which causes the central Doppler frequency of target. Moving parts of the body causes the characteristic Doppler signa-ture. When a radar signal falls on the human target which is moving toward or from the radar, the signals reflected from different parts of his body produce a Doppler shift that is proportional to the velocity of those parts. One way you can always stay hydrated is to keep a water bottle on you.This paper presents the results of time (autocor-relation) and time-frequency (spectrogram) analyses of radar signals returned from the moving human targets. This will also keep you hydrated when it’s hot and humid. Regardless of the season, a person should drink about eight 8oz glasses of water a day on average. How Much Water Should You Drink In Summer? That’s why it’s a good idea to keep a water bottle or jug with you at all times. Humid conditions will make you perspire even more. This fluid needs to be replenished by taking in water. When you’re outside in the heat, your body will sweat. If you have elderly neighbors or loved ones, check on them frequently to make sure they are staying out of the heat.

If you’re wondering how to do that, this article will show you how. It’s in your best interest to stay safe by staying cool.
The summer heat is cooking outside right now.
