In the last years, environmental monitoring was shown to be a major application field of modern signal processing and machine learning techniques. In particular, it provides some interesting problems for which specific signal methods were proposed. In this session, we aim to review some recent advances in this topic. We propose a taxonomy of the major trends in environmental surveillance accord...

The San Andreas Fault Observatory at Depth provides the most comprehensive set of data on the structure and dynamics of the San Andreas fault. We use two independent experiments recorded by the seismometer arrays of the SAFOD Pilot and Main Holes to resolve the localized structure of the San Andreas fault zone and of an intermediate fault zone at depth. From Pilot Hole recordings of the drillin...

A combinatorial hydrothermal reaction has been used to prepare pure and additive (Sb, Cu, Nb, Pd, and Ni)-loaded In2O3 hollow spheres for gas sensor applications. The operation of Pd- and Cu-loaded In2O3 sensors at 371 °C leads to selective H2S detection. Selective detection of CO and NH3 was achieved by the Ni-In2O3 sensor at sensing temperatures of 371 and 440 °C, respectively. The gas respon...

wireless sensor networks (wsns) have many applications in the areas of commercial, military and environmental requirements. regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. a basic approach for preparing a secure wireless communication in wsns, is to propose an efficient cryptographic key management protocol be...

Background and Aim: Secondary caries are a common challenge for dentists. Many researchers have evaluated the accuracy of digital radiographic systems in the detection of secondary caries and have reported controversial results. Therefore, the aim of this in vivo study was to determine the diagnostic accuracy of digital radiography in the detection of secondary caries in anterior teeth. Mate...

The designer of a sensor network protocol needs to address several low-level details such as message collisions, message losses, and resource limitations. Also, the designer needs to solve several high-level problems such as routing, leader election, and diffusing computation that are already considered in distributed systems and traditional networking. Therefore, to simplify the design of sens...

Sensor networks have been regarded as one of the emerging technologies of the 21 century and have great future scope. They have been widely used in mission critical applications like military, health as well as civilian applications. The focus of this paper is on a security of sensor networks in various fields. Security is the major concern of a wireless sensor network especially in unattended ...

Activation of voltage-gated sodium (Na(v)) channels initiates and propagates action potentials in electrically excitable cells. β-Scorpion toxins, including toxin IV from Centruroides suffusus suffusus (CssIV), enhance activation of Na(V) channels. CssIV stabilizes the voltage sensor in domain II in its activated state via a voltage-sensor trapping mechanism. Amino acid residues required for th...
