چکیده

Sensor webs are networks of sensors that can operate in a coordinated fashion, for example throughcentralized or decentralized control centers. The controller can command the sensor nodes to modify their measurement schedule or configuration in response to environmental factors or to achieve certain measurement goals. Sensor webs are envisioned as a means of providing spatially and temporally adaptive in-situ measurements for validation of remote sensing observations.

Preface: Research Topics in Semantic Sensor Networks

Semantic technologies are often proposed as important components of complex , cross-jurisdictional, heterogeneous, dynamic information systems. The needs and opportunities arising from the rapidly growing capabilities of networked sensing devices are a challenging case. It is estimated that today there are 4 billion mobile devices that can act as sensors, including active and passive RFID tags....

Acetone sensing properties of hierarchical WO3 core-shell microspheres in comparison with commercial nanoparticles

In this work, hierarchical WO3 core-shell microspheres were synthesized via a facile template-free precipitation method. Gas sensing properties of the synthesized powder to acetone and some other volatile organic compounds were comparatively investigated with commercial WO3 nanoparticles. The synthesized and commercial powders were characterized by X-ray diffraction, scanning electron microscop...
