Performance Evaluation of the Dylos Particulate Matter Sensor: A Systematic Review

open access: yesJournal of Sensors, Volume 2026, Issue 1, 2026.
Low‐cost particulate matter (PM) sensors (LCPMSs) are increasingly used to enhance air quality (AQ) monitoring due to their affordability, portability, and high temporal resolution. Among these devices, the Dylos particle counter has been widely applied in research, indoor monitoring, and community‐based studies; however, evidence of its performance ...

Pedestrian dead reckoning with wearable sensors: a systematic review [PDF]

open access: yes, 2020
Pedestrian Dead Reckoning (PDR) is the process of calculating one’s current location by using the previously known position, and advancing that position over time using established or estimated speeds and trajectories (or alternatively stride lengths and

Epidemic Patterns of Foot and Mouth Disease in the Lao People’s Democratic Republic

open access: yesTransboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Smallholder livestock farming underpins food security and rural livelihoods in Lao PDR, yet the sector is threatened by endemic infectious diseases such as foot and mouth disease (FMD). Despite significant vaccination campaigns, FMD continues to circulate widely, driven by systemic challenges including limited resources, under‐reporting and unregulated

An Indoor Localization Method for Pedestrians Base on Combined UWB/PDR/Floor Map

open access: yesSensors, 2019
This paper propose a scheme for indoor pedestrian location, based on UWB (Ultra Wideband)/PDR (Pedestrian Dead Reckoning) and Floor Map data. Firstly, a robust algorithm that uses Tukey weight factor and a pathological parameter for UWB positioning is ...
