Robust Indoor Sensor Localization Using Signatures of Received Signal Strength

International Journal of Distributed Sensor Networks, 2013
Indoor localization based on the received signal strength (RSS) values of the wireless sensors has recently received a lot of attention. However, due to the interference of other wireless devices and human activities, the RSS value varies significantly ...

Characterization of Received Signal Strength Perturbations Using Allan Variance [PDF]

IEEE Transactions on Aerospace and Electronic Systems, 2018
The received signal strength (RSS) of wireless signals conveys important information that has been widely used in wireless communications, localization, and tracking. Traditional RSS-based research and applications model the RSS signal using a deterministic component plus a white noise term. This paper investigates the assumption of white noise to have

Received Signal Strength Based Gait Authentication [PDF]

IEEE Sensors Journal, 2018
Expansion of wireless body area networks applications, such as health-care, m-banking, and others has lead to vulnerability of privacy and personal data. An effective and unobtrusive natural method of authentication is therefore a necessity in such applications. Accelerometer-based gait recognition has become an attractive solution, however, continuous

A Three-State Received Signal Strength Model for Device-Free Localization [PDF]

IEEE Transactions on Vehicular Technology, 2017
The indoor radio propagation channel is typically modeled as a two-state time-variant process where one of the states represents the channel when the environment is static, whereas the other state characterizes the medium when it is altered by people. In this paper, the aforementioned process is augmented with an additional state.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
