Activity monitoring is a technique for assessing the physical activity that person undertakes over some time. Index (AI) metric summarizes raw measurements from tri-axial accelerometers, often used measuring activity. Our research compared different groups and hand usage [1]. We also tested this as classification feature, how data acquisition segmentation parameter configurations influence accu...

in this study, the quaternary deformation and tectonic activity of saeedabad-chai drainage basin, are assessed using geomorphic approach. this drainage basin is located in northern slope of sahand mountain. north tabriz fault (ntf), is passing from the saeedabad-chai basin. variation in the morphology of mountain front provied the basis for geomorphic assessment of tectonic activity. therefore,...

Chiral media exhibit optical activity, which manifests itself as differential retardation and attenuation of circularly polarized electromagnetic waves opposite handedness. This effect can be described by different refractive indices for left- right-handed yields a negative index in extreme cases. Here, active control chirality, is demonstrated. These phenomena are observed terahertz metamateri...
