Abstract

With the propagation of sensor devices applied in smart home, activity recognition has ignited huge interest and most existing works assume that there is only one habitant. While in reality, there are generally multiple residents at home, which brings greater challenge to recognize activities. In addition, many conventional approaches rely on manual time series data segmentation ignoring the inherent characteristics of events and their heuristic hand-crafted feature generation algorithms are difficult to exploit distinctive features to accurately classify different activities. To address these issues, we propose an end-to-end Tree-Structure Convolutional neural network based framework for Multi-Resident Activity Recognition (TSC-MRAR). First, we treat each sample as an event and obtain the current event embedding through the previous sensor readings in the sliding window without splitting the time series data. Then, in order to automatically generate the temporal features, a tree-structure network is designed to derive the temporal dependence of nearby readings. The extracted features are fed into the fully connected layer, which can jointly learn the residents labels and the activity labels simultaneously. Finally, experiments on CASAS datasets demonstrate the high performance in multi-resident activity recognition of our model compared to state-of-the-art techniques., Comment: 12 pages, 4 figures

Abstract

In northern China, clove is a common plant. Its extracted eugenol exhibits a variety of biological properties, including antioxidant and antibacterial effects. This study looked at eugenol's antioxidant potential and its impact on the flora in the intestinal tract of humans. Eugenol's ability to scavenge superoxide anions and 2,2-biphenyl-1-picrylhydrazyl (DPPH) radicals, as well as its impact on the growth of common intestinal bacteria Lactobacillus and Escherichia coli, were studied at various eugenol concentrations. The results showed that different optimal antioxidant concentrations of eugenol existed for different free radicals, and the optimal antioxidant concentrations for DPPH and superoxide anion were 0.16 μL/mL and 0.04 μL/mL, respectively. Low concentrations of eugenol had no significant inhibitory effect on Lactobacillus but a significant inhibitory effect on E. coli. This research is anticipated to offer a theoretical reference for the use of eugenol in specialized dietary food applications.
