In this paper, a wireless body area network comprised of heterogeneous sensors is developed for wearable health monitoring applications. The ultimate application space is in the context of pediatric obesity. The specific task examined herein is activity detection based on heart rate monitor and accelerometer data. Based on statistical analysis of(More)
In regions of adult neurogenesis, neural progenitor cells (NPCs) are found in close proximity to blood vessels within a so-called 'vascular niche'. Neurogenesis is linked to angiogenesis via certain growth factors. We propose that angiopoietin-1 (Ang1), which is similar to VEGF, has a unique role in neurogenesis independent of its role in angiogenesis. In(More)
Wireless sensor network technology is very suitable for distributed data collecting and monitoring in tough environments such as greenhouse or cropland. This paper presents a wireless sensor network prototype with two-part framework for greenhouses. In the first part, several sensor nodes were used to measure temperature, light and soil moisture. A sink(More)
Wireless sensor network technology can provide optimal and integrated solution for distributed data collecting, delivering and analyzing in tough croplands environment. A wireless sensor network for cropland environmental monitoring is designed according to cropland application requirements. It consists of a set of sensor nodes for data sensing, a sink node(More)
Sensor nodes placement is especially important for farmland environmental monitoring applications, in which crop growing causes non-static environment for radio propagation. In order to make sure of reliable communication performance, we have conducted radio propagation experiments in crop field. The results showed pass loss of radio propagation over a(More)
Wireless sensor network can act as a distributed sampling system in precision farming applications which aim at estimating the spatiotemporal variability. Sensor nodes should be deployed referring to the communication range r c and the sampling range r s instead of the sensing range. In this paper, a kind of systematic random deployment based on three(More)
Theperformanceoftheglobalnavigationsatellitesystem(GNSS)canbeenhancedsignificantly by introducing the inter-satellite links (ISL) of a navigation constellation. In particular, the improvement of the position, velocity, and time accuracy, and the realization of autonomous functions require the ISL distance measurement data as the original input. For building(More)
