Prior research has shown the potential of device-free WiFi sensing for human activity recognition. In this paper, we show first time signals can also be used to uniquely identify people. There is strong evidence that suggests all humans have a unique gait. An individual's gait will thus create perturbations in spectrum. We propose system called WiFi-ID analyses channel state information extract features are representative walking style individual and allow us person. implement on commercial...
Remote sensing observations have shown that the far side of Moon (lunar farside) has different geology and rock composition to those nearside, including abundances potassium, rare earth elements, phosphorus (collectively known as KREEP). The Chang’e-6 (CE-6) spacecraft collected samples from South Pole–Aitken (SPA) basin on farside brought them Earth. We used lead-lead rubidium-strontium isotope systems date low-titanium basalt in a CE-6 sample, finding consistent age 2830 (±5) million...
A large proportion of ores in magmatic sulfide deposits consist mixtures cumulus silicate minerals, liquid, and melt, with characteristic textural relationships that provide essential clues to their origin. Within silicate-sulfide cumulates, there is a range abundance magmatic-textured between up about five modal percent sulfides, called “disseminated ores,” “net-textured” (or “matrix”) containing 30 70 forming continuous networks enclosing silicates. Disseminated cumulates have various...
Recent research has devoted significant efforts on the utilization of WiFi signals to recognize various human activities. An individual's limb motions in coverage area could interfere with wireless signal propagation, that manifested as unique patterns for activity recognition. Existing approaches though yielding reasonable performance certain cases, are ignorant two major challenges. The performed activities individual normally have inconsistent speed different situations and time. Besides...
Abstract Systems of sensor human activity recognition are becoming increasingly popular in diverse fields such as healthcare and security. Yet, developing systems poses inherent challenges due to the variations complexity behaviors during performance physical activities. Recurrent neural networks, particularly long short-term memory have achieved promising results on numerous sequential learning problems, including recognition. However, parallelization is inhibited recurrent networks...
Phishing websites distribute unsolicited content and are frequently used to commit email internet fraud; detecting them before any user information is submitted critical. Several efforts have been made detect these phishing in recent years. Most existing approaches use hand-crafted lexical statistical features from a website's textual train classification models web pages. However, detection few challenges, including 1) the tediousness of extracting features, which require specialized domain...
The ~216 Ma Hongqiling No. 7 intrusion is located in the southern margin of Central Asian orogenic belt, northeastern China.
